HEARTS OF IRON DOOMSDAY

Introduction

Hearts of Iron II - Doomsday is a stand-alone expansion to Paradox Entertainment’s award-winning Hearts

of Iron II, a game where you will guide your nation to glorious victory or ignominious defeat in the World

War II era, and as a result of this expansion, through a subsequent hypothetical “Doomsday” conflict between
the emerging post-war super-powers. With several Grand Campaigns, numerous Battle Scenarios, multiplayer
capability, and your choice of the more than 70 playable countries that spanned the globe at the time, Hearts
of Iron II- Doomsday will give you countless hours of challenge and entertainment.

This is a highly complex grand strategy game, not a historical simulation or FPS. With HoI2’s nearly limitless
options and exceptional depth comes a comparable learning curve. It may take some time to become familiar
with its richness and its multitude of controls, so don’t be surprised if your first few campaigns end in disaster.
There is no “right” or “wrong” way to play HoI2, and no sure way to win. You’ll probably find that the lessons
you learn in your early defeats will be just as valuable as any that you later gain through victory. Use those
experiences and don’t be afraid to experiment or save the game and then try a variety of alternatives.

While this manual will familiarise you with most of the ins and outs of Hearts of Iron II, the most valuable
resource of all are the Paradox public forums (www.paradoxplaza.com/forums). There, you can usually find
the answer to any question you might have about the game in a matter of hours, if not minutes. It’s also a place
where tips and strategies are exchanged, where people from around the world will arrange multiplayer games,
where you can read about others’ HoI2 experiences or post your own, and where new battle scenarios and
user game modifications will often be developed. This is also where you’ll find Paradox’s latest post-release
enhancements available for download as well as a large number of FAQs and other resources.

Installation

(8Mb or more recommended) / DirectX compatible sound card / DirectX9.0 or higher (included on the CD).

Installation Procedure

Place the Hearts of Iron II- Doomsday CD in your CD-ROM drive. If you have AutoPlay enabled on this drive,
the installation screen will appear automatically. If the AutoPlay doesn’t start - or is disabled for this drive - then
click Start>Run and then type X:\Setup.exe to launch the installation program (replace “X” with the drive
designation for the CD-ROM in which you placed the Hearts of Iron II CD, which is usually D or E on most
systems). Simply follow the on-screen prompts to install the game.

Keeping Up To Date

Paradox is deeply committed to its customers, and in my experience, their product support is almost unparal­leled in the gaming industry. The developers read and frequently participate in the discussions on the public
forums and will often implement some of the best player-requested features or enhancements post-release.
They also make minor tweaks or alterations to existing features and squish the occasional bug that had previ­ously escaped detection. You can go directly to the downloads page at www.paradoxplaza.com/downloads.

Getting Started

Launching the Game

Click Start>Program Files>Paradox Entertainment>Hearts of Iron 2>HoI2 to launch Hearts of Iron II’s
opening movie. Like most Paradox titles, HoI2 tends to launch a little more slowly than some games because
Paradox leaves a large number of files in simple text format to make them easily modifiable by users who
might want to tweak unit values, write their own events, or even construct new battle scenarios on their own.
This gives the game immense flexibility, but it also means that those files must be compiled when the game
loads.

For Beginning Players

If you’re new to Hearts of Iron and Paradox games, I would recommend that you begin by reading the next
section - Key Concepts - and then work your way through the game’s tutorials. These will introduce you to the
most important parts of the interface and get you up and running fairly quickly, though they focus mostly on
“how” to do something, not “why”. Once you’re more comfortable and have done a bit of your own experi­mentation, you’ll probably want to come back to the other sections where you will find detailed descriptions
of all the controls and some of the underlying strategies and tips.

My best advice would be a mixture of “don’t panic” and “be patient”. HoI2 can seem a bit intimidating and
complex at first, but once you’ve played it for a little while, you’ll find that most of its aspects are quite intuitive.
Remember that a full grand campaign game is quite lengthy and that if you rush headlong into battle without
proper preparation, you’re likely to be as successful as you would be if you were to try to do it in real life. If you
can’t find the answer to a question you have in this manual, don’t forget that you can probably get one almost
immediately on (yep, you guessed it) the Paradox public forums.

For HoI2 Players…What’s New?

If you’re a Hearts of Iron II vet, then you’ll find that HoI2 - Doomsday is based on the same engine but with
an extended timeline that now extends to 1953. New features include an expanded technology tree that allows
construction of helicopter squads, escort carriers and tactical nuclear weapons; a whole new game element of
spying and espionage; a hypothetical World War III campaign and several new or revised scenarios; a compre­hensive scenario editor…and much, much, much, much, much more!

Key Concepts

As I said in the introduction, Hearts of Iron 2 is a game of considerable complexity. It is vital to understand
that virtually every aspect of the game is interconnected. It can and will take time to learn how each of the
game elements interacts with each other, and to gain a comfortable degree of control over the nation you are
playing. The goal of this section is to give you a broad overview of HoI2’s major components and key concepts
before moving on to the subsequent sections that detail each feature and interface in turn.

Fighting the Second World War - indeed, almost every war in history - was not purely a matter of pitting
man against man on the field of battle, nor is HoI2 merely a large digital battlefield. Simply fielding a larger
army than your enemy will not ensure victory, and neglecting your economy, the so-called “engine of war”,
can imperil your chances for survival. It is vital, then, to ensure that your nation has the necessary economic
infrastructure and political wherewithal to stand against your enemies if attacked, or to support any aggressive
moves you might wish to make.

HEARTS OF IRON DOOMSDAY

A huge army might appear invincible at first glance, but it can easily succumb to a seemingly weaker force
that is equipped with more modern weapons, is in better supply, or is superbly trained and led. Elite forces can
tip the balance in a conflict, as can employing a strategy that uses terrain or weather to your advantage. Your
ability to coordinate every element of your armed forces against your enemy will also greatly increase your
chances of winning. Armies may be held in reserve or can be used to support other actions; air forces may be
used to soften up an enemy’s defences, disrupt his troops’ organisation, hamper his supply, or even gut his
industry; and navies can actively patrol enemy waters to embargo the import of much-needed resources or
even bombard and invade his shores.

The Doomsday expansion has added a further wrinkle to the game: an active spying and espionage system
that will allow a nation to engage in clandestine activities to weaken an enemy, steal its technological secrets,
and to provide information about its force composition, capabilities and strengths. Ignore such subversive
actions at your own peril!

Victory

The ultimate goal of Hearts of Iron II is to guide your nation to victory. For those who play a conventional
game, there are a number of provinces located around the globe that have a victory point value, and there are
the three main political factions: the Axis, the Allies, and the Comintern. Each campaign game has a predeter­mined end date, usually December 30th, 1953, and the victor is the faction which controls the highest point total
worth of provinces when the scenario ends. The shorter battle scenarios may have somewhat different victory
conditions, while the Doomsday campaign encompasses the post-war years and begins after the Axis defeat.

Although this is the only measure of victory recognised by the game, you might wish to consider alternate
“personal achievement” criteria if you choose to play a “doomed” nation, or a country that is not a member
of one of the factions and remains aloof. If you are participating in a multiplayer game where it is likely that
there will be more than one player on the victorious side, you may want to establish some “house rules” about
victory. The choice is yours.

The Engine of War

While HoI2 is undeniably a game that focuses on war, it is not exclusively about war. Conflict is very costly and
can involve immense expenditures in resources and lives before a victor is declared. The engine that propels a
nation through war and ultimately leads to its success or failure is its capacity for industrial production, and it
is frequently for economic or geopolitical reasons that wars are waged in the first place.

Natural Resources

If your economy is the engine that will propel you through war, then natural resources are the fuel that pow­ers the engine. Although there were hundreds of resources that historically played key roles, HoI2 distils them
into four distinct categories: energy sources, metals, oil, and rare materials. Energy, metal and rare materials
are used on a daily basis by your factories to provide you with industrial capacity (see below), while oil is
consumed by many of your armed forces (the navy, air force, and motorised parts of the army) in order to
remain operational.

Natural resources are either drawn from provinces that are under your nation’s control, or are acquired via
trade or direct cash purchases from other nations should you lack territories where they occur naturally. Any
excesses you have may be stockpiled, sold or traded to other nations who are in need. If you lack any of these,
then your economy and your military will grind to a halt, most likely dooming your nation to failure.



HEARTS OF IRON DOOMSDAY

Industrial Capacity

To continue our analogy, industrial capacity (abbreviated throughout as “IC”) is the engine that drives your
nation’s economy. This represents your overall ability to manufacture goods and is determined by the
number of factories that you have operating in your nation. The more factories you have, the greater your
potential industrial capacity. Your IC should be thought of as an ability and not as a thing. You can’t store ICs
in the way that can stockpile natural resources. You can only use them to manufacture products, up to your
daily capacity limit.

Factories require natural resources in order to operate. In HoI2, this is abstracted such that each factory
withdraws energy, metal and rare materials from your stockpiles each day in order to run at full capacity and
generate IC. If resources are plentiful, your factories will generate their full potential IC. If you run short of a
necessary resource, some of your factories will begin to shut down until you can find a new supply, usually
through purchase or trade, or through conquest. Running out of a resource altogether is almost certain to
doom your nation unless you can resolve the situation quite rapidly, so you may wish to consider controlling
your rate of resource consumption by artificially capping your production during plentiful periods. However,
shortages of fuel may be alleviated by converting some of your energy stockpile into oil, but this is a very inef­ficient process unless you have researched advanced technologies to improve the conversion rate.

IC Allocation, Production and Gearing Bonuses

Resources are consumed by factories, who in turn generate the IC you require to manufacture the various
things that you will need in the game. You will often lack sufficient capacity to do everything you want to, so
you must decide how to carefully allocate whatever amount you have. IC is used by the assembly lines that
manufacture your tanks, warships and airplanes. It produces the ammunition and supplies needed to equip
and maintain your troops. It is also used to upgrade your existing armies and to make the various consumer
goods needed to keep your population happy. A country that lacks sufficient IC will soon find its forces in disar­ray and its population in revolt. A country with surplus IC can convert this into cash which you can use to fund
research, purchase natural resources, or to conduct certain other types of foreign diplomacy and clandestine
operations…or to stockpile supplies and prepare for war. Excess IC can also be left voluntarily unused, which
conserves natural resources that might be required in the future.

A steady flow of resources and a healthy complement of factories will be vital to your success, but, as you’d
expect, this may not be quite as simple to achieve as you might like. Some resources may have to be imported
from your distant territorial holdings or obtained through trade with other countries. Your imports will be at
risk if your enemy conquers your source or actively engages in blockade and embargo activities. Further, your
industry may be subjected to a bombing campaign if you lack control of the skies, resulting in the destruction
of factories and a drop in available capacity.

An additional consideration when deciding how to allocate IC will be whether to take advantage of a possible
gearing bonus. This reflects the efficiencies of scale that are achieved through the production of many identi­cal items over a longer period of time, but it lacks some of the flexibility and easy modernisation of a more
generalised approach to manufacturing.

Infrastructure

Without the necessary infrastructure of roads and railways, it is difficult to efficiently move men and equip­ment throughout your nation. Factories may only be built in provinces that have enough existing infrastructure
to deliver the necessary raw resources and then to transport the finished goods away from them, and the
construction rates for some provincial assets are greatly accelerated by higher levels of infrastructure. Your
armed forces will require these same assets to assist their movement and to efficiently bring supplies and fuel

HEARTS OF IRON DOOMSDAY

from regional depots to the forces on the front lines. If you have insufficient infrastructure due to poor planning
or because it is reduced by an enemy’s campaign against you, then your troops will slow to a crawl and run
short of supplies, which will greatly reduce your combat capabilities and increase your rate of attrition (loss of
troops and equipment due to illness, mechanical breakdowns, etc.).

Domestic Policies and Government

While HoI2 places you in supreme command, it would be impossible for you to govern every single aspect
of your country. Instead, each nation has a set of domestic policies that determine what type of government is
in place, what its trade practices might be, what type of army it will field, and how large a say the government
permits its population in its affairs. Democracies in particular have strict limitations on the diplomatic actions
they may take without provocation.

Domestic policies have numerous effects in the game, the most prominent of these being that they determine
who will govern your nation and who will serve in your “cabinet” to attend to the myriad of little details that
need taking care of on a day-to-day basis. They are not advisors in that they don’t make suggestions to you
as you play, but their individual characteristics will accord bonuses or penalties to your actions. Some may be
adept at foreign relations, others may provide a boost to your economy, while still others may champion mili­tary doctrines that will benefit your armed forces in certain ways. Domestic policies also have individual effects
that may affect your industry, recruitment, public sentiment, intelligence activities, and foreign interactions.

You will begin the game with a set of domestic policies that reflects your selected nation’s historical situation
at the time. During play, you may periodically make minor adjustments to your policies, which could result in
some changes to your government and the people that serve on your cabinet. However, you are generally
prohibited from making drastic or rapid policy reversals except through a few very special circumstances.

Dissent and Partisans

Depending on your domestic policies, your population may also play a prominent role in determining what
actions you may take, even to the point of making it impossible to declare war on a nation unless public
opinion is on your side. Policy settings will also influence the public’s demand for consumer goods, and failing
to meet these demands will have negative consequences by increasing dissent, which represents the popula­tion’s overall level of unhappiness. Dissent has three significant impacts: it will cause your troops to fight more
poorly; it will reduce your industrial capacity; and it will greatly increase the likelihood of your public rising in
open rebellion against you. You can control dissent by reducing it or at least mitigating it somewhat by allocat­ing a larger share of your IC to the manufacture of consumer goods, though this will reduce your ability to
meet the production and supply demands of your military. Providing excesses of consumer goods will reduce
dissent, while falling short in this area will cause dissent to increase. Dissent will also increase in response to
shortfalls in military supply. You will need to maintain a careful balance between the needs of your military and
the happiness of your subjects throughout the game.

Captive populations (the people who live in foreign provinces that you occupy) will be much less interested
in working for you and are far more likely to rebel than ones who feel that they naturally belong under your
rule. Partisans (nationalists who remain loyal to their former government and oppose your occupation) will
reduce a province’s industrial capacity and supply efficiency and may also become openly militant if you fail
to maintain sufficient forces to keep them under control. An alternative to maintaining rigid military control is
to voluntarily grant partisans their freedom, allowing them to form a new nation and establish a government
of their own. You will lose the majority of the economic benefits from provinces they are granted, but they
will generally be friendly towards you if you allow them their sovereignty; conversely, if they achieve freedom
on their own, you will lose all economic benefits and the fledging nation will actively side with your enemies
and seek to destroy you.

HEARTS OF IRON DOOMSDAY

Diplomacy and Trade

International diplomacy will also be a significant component of your success. There are many diplomatic
options available to you, including negotiating one-time exchanges of goods, arranging open-ended trade
agreements, forming alliances or declaring war, and your ability to do any of these will depend on the type
of relationship you have with the nation involved. HoI2 keeps track of evolving international relationships on
which many of its actions or its willingness to agree to diplomatic proposals are based. Fortunately, you have
some diplomatic options available to you that will help you to improve your relationship with other countries,
although any hostile actions you make will tend to undermine these efforts.

It’s rare that a nation can stand alone against the world, so you will probably wish to be part of an alliance. Al­though limited alliances are possible between almost any two or more nations, HoI2 considers the three main
historical factions to be of paramount importance: the Axis (led by Germany), the Allies (led by the United
Kingdom) and the Comintern (led by the Soviet Union). Depending on the historical situation, some nations
will begin the campaign or scenario already a member of an alliance, while others will be neutral. As the game
progresses, the factions may attempt to influence other nations to join their alliance, or neutral countries may
even petition to join an alliance if they have a good relationship with its members. Alliances may freely move
forces and trace supplies through the territories of their member nations. They will frequently supply friendly
forces and can lend divisions or even entire armies to an ally when the situation warrants that they be under
their control. Neutral territories must be respected at all times, meaning that movement and the tracing of sup­ply is prohibited unless you can negotiate military access for your troops with that nation’s government.

The other major diplomatic activity you will conduct is trade. You will probably establish a number of open­ended trade agreements where you will exchange resources, cash or goods with other countries on a daily
basis in order to meet your respective industrial needs. You can also negotiate one-time deals of this nature, or
more complex trades that involve the exchange or purchase of land or even technological blueprints. You are
also able to simply donate resources, land, blueprints or even equipment to another nation if you wish.

The success or failure of your diplomatic attempts will depend on the domestic policies, cabinets, political
leanings and size of the two nations involved. It will also vary with the attractiveness of a proposal and the
relationship that exists between them. Not surprisingly, the more harmonious two nations are, the more likely
it is that an offer will be accepted and the more balanced a deal they may be willing to negotiate. Successful
diplomacy can even be its own reward, since each successful effort will usually improve your relationship.

Intelligence

The Doomsday expansion has added another key ingredient to the mix: the ability to wage a clandestine
war where spies may be sent to other nations to engage in a variety of operations. These include stealing
technological blueprints, assassinating another nation’s ministers, engineering a foreign coup, influencing the
global opinion of that nation, sabotaging a nation’s production or research, fomenting dissent, and to create
and support partisan activities. If that nation has a nuclear arsenal you may also instruct your spies to try to
destroy those dangerous weapons.

Spies and associated intelligence technologies also provide vital information about the other nations around
the globe that would otherwise remain hidden. In order to evaluate the chances of launching a successful
campaign against an enemy, you should consider it essential to first determine the capabilities of its military,
technology and industry. Similarly, you should devote some resources to ferreting out your enemies’ spies
to prevent any similar activities within your own nation. Success or failure could easily tip the scales in any
subsequent conventional conflict.

HEARTS OF IRON DOOMSDAY

Technology

Another key domestic activity you will engage in is the research of new technologies. Some of these will
improve your industrial capabilities, but the majority of advances are designed to enhance various elements of
your armed forces. You may discover superior military doctrines, better arms and armaments, larger tanks and
naval vessels, advanced aircraft with greater range, or more subtle advances such as systems that allow better
observation of enemy movements or detection of their forces. You may even decide to pursue and deploy
atomic weaponry. Needless to say, falling behind in the arms race is not likely to be a good idea, unless you
can meet your enemy with overwhelming force, and even then, victory is not assured.

Research is conducted by funding teams of scientists to work on research projects. The number of projects
you can conduct simultaneously will depend on your overall IC (a large nation can have as many as five
projects ongoing at a time), and the nation that you select will determine the variety and calibre of your avail­able teams. You will need to assign teams to your projects with some care, since each team will usually have
a skill level and certain areas of expertise associated with it. One that excels at avionics, for instance, can be
expected to produce positive results in a new aircraft design far more rapidly than it would if you asked it to
work on finding a better hull for your submarines. The length of time it will take to research a project depends
on your teams’ abilities, their overall skill level, the project’s complexity, and your ability to maintain a steady
flow of funding to the team.

Once you have achieved a new level of technology, you will need to implement it. In most cases, existing
equipment can be improved by allocating IC to its upgrade. Major breakthroughs for technologies that haven’t
previously existed as well as significant naval model upgrades must be manufactured from scratch. You have
the option to keep as much obsolescent equipment in the field as you like, although you may also choose to
upgrade it or scrap it to recoup some of its manpower.

Preparation and Support of the Military

There are many components that must fall into place for a campaign to be successful. Armed forces must
have access to a continuous flow of supplies and ammunition if they are to remain in fighting form, and they
will need strong and capable leaders who are able to command them effectively while maintaining an overall
level of discipline and organisation. Factors such as terrain, weather, and the placement of defensive structures
will greatly influence their performance, as will their previous experience in such combat situations.

Supply, Outfitting and Transport Capacity

Your ability to supply, outfit and transport your troops will be vital to your military success. Armies require
ammunition and food (supplies) to fight. Motorized vehicles, aircraft and naval vessels will also need fuel (oil)
if they are to remain operational. For overseas engagements, you will also need to be able to move men and
equipment great distances that are too far or impossible to reach by normal means. Failure to supply your
forces will not only result in a reduction of their operational capabilities but will also increase your level of
public dissent

You will need to heed and maintain your supply chains to avoid having your armies end up in disarray and
unable to fight. Supplies are manufactured by allocating IC to their production and then are transported to your
forces along your supply chains. This can involve ground supply (using your provincial infrastructure), naval
supply (via convoys), air supply (via your airborne transports), or a combination of these, all of which can also
be disrupted by enemy actions. If your supply chains are damaged or cut by the enemy, or if you lack sufficient
oil and supplies for your military, your chances of survival are exceedingly slim.

There is also the issue of transport capacity to consider. This reflects the infrastructure such as roads, railways
and such that are in place to move large volumes of materials and men in a reasonable period of time. Each

10

11

HEARTS OF IRON DOOMSDAY

province has an infrastructure level which you can increase that will limit this volume and can be damaged or
otherwise diminished by enemy aerial bombardment. Sea supply demands that you devote enough convoys
to the task and have an available port to offload those supplies. If those convoys are left undefended, they
can quickly fall prey to enemy submarines, surface vessels and even aerial bombardment, so you will need to
provide escorts or other protection for them as well. Airborne supply tends to be very tricky and not particularly
efficient because the capacity of the aircraft is limited, they require fuel to operate, and unless you assign them
some protection, your enemy’s fighters will probably shoot them out of the skies faster than you can replace
them. Nevertheless, this is a method of keeping your troops alive until you can find an alternate means of
getting resources to them.

Don’t be surprised to find an enemy actively engaged in disrupting your supply, particularly if he enjoys naval
or aerial supremacy. Of course, you can employ similar tactics, disrupting his supply and encircling his troops
to devastating effect.

Organisation and Entrenchment

Land forces that are constantly moving don’t have much time to prepare themselves against an enemy attack
and have a tendency to become somewhat “stretched out” or disorganised. The same is true of armies that
are constantly subjected to naval barrages or aerial bombardment. HoI2 models this aspect of war using the
concepts of organisation and entrenchment.

Organisation is a measure of the cohesiveness of a force, which is a representation of how able it is to receive
and respond to orders, how well it is supplied, how competently and thoroughly its command structure has
been established, and is also an indicator of its general morale. Each of your units, be they land, naval or air,
must have a sufficient level of organisation to engage in battle, and without it they will break and retreat in
disarray. A force that is engaged in combat will begin to lose organisation, and the longer it continues to fight,
the greater the loss will be. The addition of new recruits to replace casualties will also reduce organisation
proportionally to the number of newcomers added, and if a unit finds itself without a source of supply, then
organisation will plummet rapidly.

While moving, a unit’s organisation will usually remain static unless the terrain it is traveling through cannot
support the size of the force, or if it is moving without supply. If it ceases its movement and avoids battle for a
while, then its organisation will gradually recover. The maximum organisation is determined by its leadership
and experience (see below) and can also be increased through the research of various combat doctrines and
equipment advances.

A land unit that is stationary for a time will also begin to entrench itself in a province by selecting the most
defensible ground, preparing foxholes and snipers’ nests, establishing command and aid stations, organising
munitions, and so on. This will give the unit a bonus in any subsequent defence of that province and can
make it difficult to overcome without a concerted effort on the part of an attacker. The longer a force remains
in place, the more “dug in” it will become. However, this entrenchment bonus is immediately lost if the unit
moves, and even if it later returns to the province, it must begin the process from scratch.

Command, Leadership and Experience

The effectiveness of a force relies heavily on its combat experience and on the officers that you assign to
your front-line commands. Each time a unit engages in battle, it will gain some valuable combat experience
and through the course of time and repeated conflict, it will begin performing noticeably better. The resulting
veteran units may become the backbone of your armed forces, but as they suffer casualties, their losses will be
replenished with green recruits which, not surprisingly, dilutes their effectiveness.

Individual units may be instructed to act independently, but most often you will wish to group them into
larger forces, often using a mixture of unit types to achieve the desired overall balance and combat effective-

HEARTS OF IRON DOOMSDAY

ness. Commanding larger numbers of units requires special leadership skills that are possessed by only a
handful of people, so you will need to draw from a pool of your officers, assigning someone to lead each of
your forces. Various officers will have different skills or areas of expertise, so selecting the right man for the job
can be extremely beneficial. Each officer also has his own level of combat experience which will increase as
you continue to employ him. You may find that at some point you may wish to promote him to an even higher
rank in your military, increasing the number of individual units he can command without incurring a penalty.
Junior ranked officers tend to accumulate experience more rapidly than senior ones however, so this will often
prove to be something of a balancing act.

Very large-scale operations bring an added level of complexity to the overall command. It is one thing to issue
orders to a collection of divisions all occupying the same general location, but another thing entirely to manage
multiple army groups, whole armies, or even multiple armies assembled along a front. In such instances, you
will likely need to establish special headquarters divisions, a unit unsuitable for direct combat which improves
the overall supply efficiency of large numbers of forces and gives them a greater likelihood of achieving posi­tive results. When you are considering massive offensives or the defence of an entire front, this special division
can have a dramatic effect on the overall success of your operations.

In a larger sense, however, you will always be in ultimate control of your military and it will be up to you to
plan your attacks and arrange for suitable defence of your territories. HoI2 includes some handy features that
make it as easy as possible to coordinate your forces and use them to maximum effect, and to assign long-term
missions that your officers will then proceed to carry out unless you instruct them to do otherwise. Leadership
and experience simply help to determine how effective they will be in fulfilling your orders.

Defences and Fortifications

While armed forces are required to protect your territories from the enemy’s advances, there are up to three
different defence installations that you may be able to construct to help improve your chances of defeating
an assault. If you have the required technology, you can also build radar sites to improve the effectiveness of
your aerial defences.

The construction of defences requires a commitment of IC until their production is complete. They can be
damaged by enemy attacks, requiring further allocation of resources to repair them, and they can be captured
and used against you if they fall into enemy hands. Each of these installations can be enhanced through further
IC investment, thereby increasing their size, quality and effectiveness. This is a worthwhile investment and can
become the difference between successfully warding off an enemy’s assault and succumbing to his advance.

Land fortifications are a network of bunkers, gun emplacements and minefields that you can construct in a
province to help your army repel enemy land forces. They are particularly effective in protecting your infantry
from tanks, mechanized units and artillery forces where they might otherwise be overrun or destroyed. They
also offer some shelter from aerial bombardment although they are not designed to actively counter such
attacks. A land fortification offers no resistance by itself and must be manned to have any effect.

Entrenchment bonuses are combined with land fortification bonuses, resulting in an almost insurmountable
defence if a force remains stationary for long enough in a province that has been heavily fortified. A good
example of this would be the French Maginot line at the onset of the war, an obstacle that the German high
command wisely chose not to approach with a frontal assault. The only methods of dealing with forces that
are stationed at such a defence are to bombard them over a long period of time, cut off their supply and hope
to starve them into submission, or to take your admittedly poor chances with a series of massive successive
assaults on their position. Should they be available to you, paratroopers will bypass defensive fortifications and
may be an effective component in an assault, although they incur other penalties and are usually fairly lightly
armed. Needless to say, your best bet is to use a combination of all of these strategies whenever possible.

Coastal fortifications are a similar series of trenches, gun emplacements and other devices constructed along
the shoreline of a province and must also be manned by your troops if they are to have any effect. They will
present a major obstacle to enemy troops attempting to land in the area. Even an elite marine unit will find it
hard to break through to establish a beachhead.

Anti-aircraft guns offer a third possible means of defence. Unlike land and coastal fortifications, anti-aircraft
guns do not need to be manned by your forces in order to operate, as their construction includes a manpower
component. Their function is to provide added defence against air missions flown against targets in the prov­ince and to disrupt any enemy aircraft that pass overhead. They will not in any way help to defend you against
the assault of a ground force or naval invasion. Enemy aerial attacks against factories, infrastructure, bases,
other fortifications, or any forces stationed in that province will be subjected to withering return fire from your
anti-aircraft batteries. This will not only hamper the inbound flight’s organization, thus reducing the impact and
extent of the damage from the attack, but it will also most likely inflict a number of casualties as well. Enemy
squadrons whose missions require that they fly through the region will also be subjected to fire, although to
somewhat lesser effect.

If you have researched the necessary technologies, you will also be able to build radar sites in your territories.
These stations will greatly improve any aerial defence that you mount in that province against enemy bombers
and fighters, and may also allow you to detect approaching enemy naval vessels and aircraft in an adjacent sea
zone. Radar sites do not need to be manned by your troops to be operational.

Naval and Air Basing

Military vessels and aircraft usually have special requirements that necessitate the construction of dedicated
port facilities and air fields to fully meet their needs. Hearts of Iron II simulates this by using a system called

basing.

Each squadron must be assigned to an air base that is located in a province that you control or that is friendly
to your forces, and all operations that it conducts must be launched from that base, to which it will return after
the mission has been flown. If you assign too many air wings to too small a base, then you may find that the
ground staff will have trouble maintaining and servicing all of those aircraft in a reasonable period of time. You
can either enlarge the base to increase its capacity to a predetermined maximum size, or reassign some of the
squadrons to a different base that has sufficient space for them. If there isn’t a suitable location, you can also
construct a new base to house them, although this will take some time to prepare.

Similarly, naval bases are needed to act as home ports for your fleets. Ships are assigned to them and must
return periodically to conduct minor - or not so minor - repairs. Any number of ships may use the same naval
base, although a base’s size determines how rapidly it can repair those vessels, and its location will affect
what seas your navies will be able to patrol. Existing naval bases can be enlarged with certain restrictions, and
new ones can be built. There are also many provincial ports that your fleets may use as temporary moorings;
however, those harbours lack the facilities to carry out any repairs or offer supply to your vessels.

Bases are susceptible to bombardment and can fall into enemy hands. Enemy aircraft can be given missions
to strike at your ports or crater your runways, reducing their basing capacity and forcing you to spend time
and resources to repair them. If you lose control of a province that contains a base, then any forces that used
it as “home” will find themselves out of supply and forced to rebase. What’s more, your foe will be able to
use the captured facility as a new base for his forces, once he has effected repairs to the inevitable damage it
sustains during its capture. You should pay close attention to the locations of your enemy’s bases and either
render them inoperative or consider attempting their capture, while taking precautions to prevent the enemy
from doing the same to yours.

Weather, Terrain and Time of Day

Weather and terrain played significant roles in the outcomes of historical military operations. It was the onset
of winter that did much to halt the initial German advance into Russia in 1941, and it was Burma’s inhospitable
terrain that added a heavy toll to the loss of life in that region. Most military actions also had to be conducted
during daylight hours, since target recognition was very poor in an era when human eyesight was more or less
the only available instrument. All three conditions are taken into consideration in Hearts of Iron II.

Weather is synthesized in-game according to a complex random model and will play a prominent role in
your games. Both rain and snow will have a negative effect on your military operations, reducing units’ combat
effectiveness, quite significantly in some cases. Combat resolution also includes a “visibility” component which
adverse conditions will reduce, unless specialised equipment has been discovered by your scientists and
supplied to your forces.

Certain types of terrain will also reduce movement speeds, hamper supply, and impose penalties to combat.
The effect will vary depending on the unit type, generally impacting more severely on motorised units than
on foot soldiers, and in most cases the terrain will give a defender an advantage, reflecting his ability to make
strategic defensive use of the landscape.

Hearts of Iron II is played on a global stage over a period of years and includes accurate modelling for both
local time of day and for seasonal variations in the length of a region’s daylight hours. Most units perform
very poorly in the hours between dusk and dawn when visibility is poor, so you will need to take this into
consideration when planning your attacks. Certain technological advances may mitigate this somewhat, but
you will probably have better success if you plan your large-scale operations to begin shortly after dawn during
seasons when the daylight hours are long.

Combat

Hearts of Iron 2 does not seek to model combat on a highly detailed, microscopic level. You do not control
individual soldiers, squads, platoons, companies or even battalions. In HoI2, you will issue orders to divisions
or whole armies, and your battles will represent a contest for the control of much larger regions of land such as
provinces rather than individual beachheads or buildings. The actual hand-to-hand fighting occurs behind the
scenes in your CPU and your progress is displayed using graphic and numeric feedback as combat ensues.

Movement is Attack for Land Battles

A significant change in actual battle mechanics was introduced in Hearts of Iron II. In previous Paradox games

- and many other strategy games, for that matter - a land force would be ordered to engage an enemy in a
neighbouring province, move there, and then upon its arrival, combat between the two would ensue. The loser
would then retreat from the province and the victor would remain. This is not the case in HoI2. Instead, the
game employs the concept of “movement is attack” in all land-based battles.

Combat is initiated as soon as a land force begins to move towards an enemy province that is being defended.
The battle will rage on until one of the sides has gained the upper hand, at which point either the aggressor’s
movement is discontinued if it loses, or the defending force begins to withdraw and the victorious attacker
concludes its movement into the province and assumes control. This system alleviates a number of common
issues such as being unable to tell where an enemy unit is moving until it is too late, and also offers a number
of new operational possibilities for both the attacker and the defender. Forces in adjacent provinces may sup­port the armies involved in the battle, and behind-the-lines reserves may be positioned to make a last-ditch
effort to shore up the defences. Air and naval battles, however, do not use this combat method and will contest
an air or sea zone while jointly occupying it.

Orders

If you play a larger nation, you will find that the sheer number and geographic separation of the forces you
field can make them daunting to manage. To reduce the micromanagement requirements and allow you to
focus on the zones of greatest activity, HoI2 permits you to give standing orders to most units. When you are
initiating a large-scale assault involving large numbers of units or a combination of land, naval and air forces,
you will also need to carefully coordinate these attacks to achieve maximum effect. The game’s order interface
makes this surprisingly easy to achieve.

Each unit has a useful set of orders that may be given to it beyond the basic “move here” or “attack right
now” commands. Depending on the unit type, an available option is selected on the order interface and the
force will then carry out the orders exactly as you have instructed. The specific options are detailed later in
the manual, but the concept that you should understand is that the order interface includes the ability to set a
date and time that you would like a force to begin an action, allowing you to coordinate the orders of multiple
units. In many cases, you will also be able to set a date and time or operational condition for it to discontinue
operations, or even give a unit a set of standing orders to repeat the same mission multiple times, allowing
you to focus your attention elsewhere while it goes about its business.

Air and Naval Combat

Air and naval operations do exist, of course, but are abstracted to a large degree in Hearts of Iron II; other­wise, the added level of complexity would be overwhelming to most players. You will usually assign general
orders to each air wing or flotilla, giving specific time period and other parameters that you would like it to
follow, and you may then essentially leave it to its own devices to carry out these operations until it receives
new ones or the orders expire.

Game Options

Difficulty: There are 5 levels of difficulty which apply global modifiers to most aspects of the game,
such as industry, resources, combat, movement, and more. At easy and very easy levels, the AI
nations will be handicapped and the player will be given artificial bonuses. At hard and very hard
levels, the reverse is true. You can see and even change the precise modifiers used by looking at the
difficulty.csv file in the db folder.
A.I. Aggressiveness: This adjusts how the A.I. reacts to the player’s actions during the game,
ranging from “coward” to “furious”. At furious level, the AI will tend to declare war at the slightest
provocation and will be considerably more actively militaristic, while at coward level the AI will tend
to be more conservative and generally defensive.
Game Speed: This can be set prior to starting a game or from within the game itself using the
“Ctrl” and “+” or “-” keys. In a multiplayer game, only the host may change the game speed.
Share Countries: Change this to “ON” for a multiplayer game where you wish to allow more than
one player to be able to select the same country. This option is disabled in single player games.
Autosave: This allows you to set how often the game will automatically save, which may be
changed from within the game via the options menu. In multiplayer mode, only the host computer
will save the game.
Use Counters: By default, HoI2 uses animated sprites to display your units on the map. Enthusiasts
may wish to toggle this to “ON” to have units displayed as traditional NATO counter pieces. instead.
This can also be done in-game by right-clicking on the “pause” button.

HEARTS OF IRON DOOMSDAY

This is not to say that combat won’t occur between these forces; it will, and quite frequently at times. When
this occurs, there are special rules that govern the engagements which take the types of units involved into
consideration, as well as the time of day and weather conditions. Aerial combat is further limited by the range
of the aircraft involved, as they will eventually need to break off and return to base to avoid running out of
fuel and ammunition.

It is vital to understand that neither sea zones nor the air space above provinces are subject to control in
the way that the provinces themselves are. There is no “ownership” of them, and neither aircraft nor naval
vessels are capable of capturing a province. Most often, you will use them in support of your armies, seeking
to soften up an enemy’s resistance through bombardment or to hamper or even cut off his lines of supply.
Combat between them will therefore most likely be a contest to determine whether you are able to carry out
these goals.

The Fog of War

This doesn’t refer to a weather condition, but rather to darkened regions of the map where the game will
hide things from you that you aren’t in a position to know - namely, the dispositions of other nations’ armed
forces. It is assumed that you will have sufficient reconnaissance and intelligence sources to determine some
basic information about provinces, even in your enemy’s territory, but you will be unaware of the location of
any forces that don’t belong to you and are outside your territory or beyond the sighting range of your units.
You will be aware of enemy units occupying provinces adjacent to your troops, but you will usually have
only a very vague idea of their complement and size until you engage them. You may also wish to fly several
long-range missions deep into enemy territory prior to an attack in order to gain additional information about
possible reinforcements and reserves that the fog of war will otherwise obscure. Keep in mind that some units,
particularly submarines, are able to hide their presence, but that there are also technologies you can research
to assist you in detecting and identifying them.

Connection Types

You will need either a fast Internet connection (DSL/Cable with TCP/IP protocol installed) or a con-

nection to a Local Area Network (LAN) to play HoI2 in multiplayer mode.

LAN: This connection is established automatically by searching for any hosted games on your LAN.

Either click “host” or select a detected game and click “join”.

Valkyrienet: This is a service provided at no charge by Paradox as both a meeting place for players

and a connection handler to make it easier to host or join games. HoI2 also allows the host to set a

password that guests must enter to be able to join private games.

Internet: You will need to enter the IP address of the host computer in order to join an internet

game. This can change each time the host connects to the internet if it is not a permanent con-

nection. If you are hosting a game, you can determine your IP address by establishing an internet

connection and then chose Run from your computer’s Start menu.

If you are using Win98 or WinME, type winipcfg and then click OK. Make a note of the IP Address

and then communicate it to your guests.

If you are using Win2000 or WinXP, type cmd and then click OK. In the new window that appears,

type ipconfig. Make a note of the IP address and then communicate it to your guests.

Routers and Firewalls

It is common for computers to be “behind” routers or be protected by firewalls.

Firewalls: vNet and internet multiplayer games use ports 2300-2400, 28800-29000 and 47400-

47700 for communication. You will need to make these available to host or join a game. Note that

this will result in limited exposure to malicious internet users and that you do so at your own risk.

Routers: Since there are many different routers on the market, each with unique software controls,

please consult your user manual for details. You will also need to have a network client installed in

Windows networking. If you’re having trouble, ask for help in the HoI2 Multiplayer subforum on

Paradox’s website.

Known Issue: Please be aware that there is also a known DirectX-related issue that may cause

clients to “drop out” of a multiplayer game if both the host and a client are behind a NAT-enabled

router and the game is paused for longer than 30 seconds. This issue is unresolvable through game

coding, so it is recommended that another (non-NAT) host be chosen, or that any long pauses be

avoided (try temporarily reducing the game speed to a crawl instead).

The Doomsday expansion has further extended the fog of war to reduce the certainty of your knowledge
of more general information, such as the total forces or technological position of any nation that is not part
of the same alliance. Fortunately, your allies will share all of their intelligence and force dispositions with you
as well.

Strategic Redeployment and the Force Pool

Any new military units you produce will enter your force pool and can then be deployed at your discretion
to any valid location. Naval forces and air forces have an additional deployment prerequisite: they must be
assigned to specialised bases that are constructed to house and support them. These bases are limited in the
number of units they can effectively handle, and this number can be temporarily reduced as a result of dam­age from enemy attacks.

Land units that are already in the field may be temporarily withdrawn from active service and strategically
redeployed elsewhere without the need to manage their exact movements. As long as they don’t have to cross
water, which requires the use of naval transports and thus active management, they will arrive at their new
posting after a period of time. This redeployment method is not possible for naval or air forces, which must
be rebased via conventional means.

HEARTS OF IRON DOOMSDAY

The Main Menu

To begin playing Hearts of Iron II, click Start > Programs > Paradox Interactive> Hearts of Iron 2 > HoI2 and
after a moment or two, the opening movie will play. You will then see a status screen displaying the progress
of the main game engine’s loading process, and once this has finished, you will be presented with the Launch
Menu. This gives you the options to start a single player game, start a multiplayer game, play the tutorials, view
the game credits, or exit the game.

Single Player Games

Most often, you will probably be playing
a single player game, pitting your skills
against the computer. Click “Single Play­er” on the Launch Menu and the main
menu screen will appear.

Selecting a Scenario or Save
Game

When starting a new game, you will
select from a list of available grand cam­paign games or battle scenarios (area 1).
Grand campaign games use the entire
globe and allow you to play any available
nation in the world, starting with each

date in WWII and then progressing until the end date in December 1953.

Battle scenarios are usually more limited in scope, focusing on short, specific engagements and often re­stricting the nations that may be selected and even the part of the globe that can be used. Many of these
scenarios disable some of the game’s more complex interfaces, providing the player with only scripted forces,
replacements, and resources with which to accomplish their goals, and usually have special victory conditions.
The battle scenarios are great for playing fairly short “what if” games around major offensives, or for one-time
multiplayer games. For the purposes of this manual, I will assume that you have selected a grand campaign
game and that all interfaces are available to you.

Once you have begun play, you can save your game at any time. To load a saved game, simply scroll through
the list of file names (area 2) and select the one you wish to resume.

Selecting a Nation

After you have selected a grand campaign, battle scenario or saved game, the nation selection portion of the
main menu (area 3) will display up to ten national flags. Click one of these to select that nation and to display
a brief overview of its historical situation during that era. If you don’t see the flag of the nation you wish to play,
right-click on any of the flags to display a list of additional nations and select the one you want. If you still can’t
find the desired nation, then either it doesn’t exist (it has been eliminated from the game due to conquest) or
you have selected a battle scenario where that country is not available for play.

Changing the Game Options

At the bottom of the screen (area 5) you will see three buttons. Click the Options button to change the set­tings to suit your preference (see sidebar). If you make a change, this will be displayed in the log area of the

nation’s historical position at a significant

1

1

HEARTS OF IRON DOOMSDAY

main menu (area 4). If you don’t change anything, the game will use the same settings as the last time you
played or will use the default settings if this is your first game. If you made a mistake and intended to play a
multiplayer game or tutorial, you can click the Back button to return to the start menu.

Launching the Game

Once you have selected a country and changed whatever options you wish, click the Start button to begin the

game. This button will remain greyed out until you have selected a country.

Multiplayer Games

Multiplayer games are started in much the same way that a single player game is launched; however, there
will be at least two additional steps to perform before you may begin play. One player will act as the “host” of
the game and the other players will join as “guests”. Up to nineteen additional players may join and I would
recommend that the player with the fastest and most stable connection be chosen for internet games, since
this has a greater impact on performance than the host’s computer specifications. If connection speeds are
equal, then the player who has computer with the best performance should be the host. Only the host may
select the scenario or saved game to be played, and only the host may change the game options.

When you click the Multiplayer button on the initial menu, you will be asked to specify the type of connection
you wish to use (see sidebar) and to enter your name. Type your name in the space provided and then click
the button that corresponds to the connection type you wish to use. Unless you are using Valkyrienet (vNet),
you will then be asked whether you wish to host a game or join a game as a guest. Note that all players must
be using the same version of the game, though this is checked automatically when the connection is first
established in order to ensure that there are no file discrepancies. I also recommend that you disable any non­essential software that might be running in the background on your computer as this will often affect stability.

The vNet connection will take you to a free service where players frequently meet to start new games. Since
vNet supports all of Paradox’s games, you will need to select the HoI2 channel from the channel listing which
will take you to a chat location where you can arrange a new game. Once you’ve found a few people to join,
you must designate a host. Since vNet can be busy at times and some people have expressed a desire to be
able to create “private” games, HoI2 now allows the host to set a password that must be entered to join a
game. Once you’re ready, the person who is hosting will click the Host button and type in a password. The
other players will soon see the game listed and should select it, click Join and then type in the password when
prompted. The connection will be automatically established by vNet. Note: Once you start the game, the con­nection is handed off to the host and the game will disappear from the vNet list.

Once you’ve established a connection, the main menu screen will appear, although you will notice a few
differences. Saved games will now be found at the end of the scrollable list in the game selection area (area 1)
and a listing of all players will now appear in the area at the bottom left of the screen (area 2). I hope that you
never need to use it, but the host also has the ability to ban a guest from the game by highlighting the player’s
name and clicking the Ban button. On a more positive note, you are also able to chat with other players while
viewing this screen by typing in the space below the narrow line in the log area of the screen (area 4).

The host may now select the scenario or saved game to be played. If a saved game is chosen, then there will
be a brief pause as the game is compressed and then the transfer process will begin to send the save game file
to the other players. You will see a status indicator beside each player’s name, indicating whether the transfer
is still in progress or whether it is complete. I strongly advise players to wait until everyone has completed this
transfer before selecting countries, since this is a common source of subsequent problems. Most players who
frequent vNet follow a protocol whereby all players wait until the host has confirmed that everyone has com­pleted the save game download. The host will then select a nation which signals that it is safe for the guests

HEARTS OF IRON DOOMSDAY

Message Settings

HoI2 allows you to customise the way that messages are displayed. Each type of message may be
selected and set to display in one of the following ways:

Do Not Display: Use this setting to suppress this message from displaying at all.
Display in Log Only: These messages will only display in the history log
Message Notifier: These messages display a small icon on the right side of the screen. Clicking on

it opens the message box. (This option is not available for all message types.)
Message Box: This setting is for more important information and will cause messages to appear in
a large message box as well as being recorded in the history log.
Message Box with Pause: This setting will bring up a message box and pause the game until you
click “okay” on the box. Note that in multiplayer games, the auto-pause function is disabled and this
message will simply bring up a message box.

to do so as well. I would also advise against using the Windows operating system’s Alt+Tab ability during the
download as this will almost always cause the transfer to freeze or become corrupt. With a decent connection
speed, this process shouldn’t take very long and you can safely chat with one another while waiting.

You will notice that the game options submenu now allows you to change the Share Countries setting to
“yes”. This allows more than one player to select the same nation, which is otherwise prohibited. If two or
more players up to a maximum of ten play the same nation, then each of these players will be able to use any
interface or control for that country. There are no limitations, so I would recommend you agree on areas of
responsibility ahead of time to prevent disagreements during play.

Once all players have selected their nations, the Start button will become active for the host. When the host
clicks this, the scenario or saved game will launch on each system and when all players have finished this
process, with slower systems taking longer to complete the launch, the game will begin. Another vNet custom
that I recommend for any multiplayer game is for each player to use the chat feature to type “in” or “here”
once the game has launched.

You may also chat with one another during the game by pressing the tab key, typing a message, and pressing
the enter key. You have the ability to make your chats “private” by selecting the player (or players) you wish to
have receive your communications. For your convenience, there are several preset chat filters that allow you to
quickly address messages to the people you wish. After you press the enter key, the chat message will display
on the recipient’s main game screen and be recorded in his history log.

There are a few other important differences between single player and multiplayer games. The game speed
setting may be adjusted during play using the “Ctrl” and “+” or “-” keys, but this may only be done by the host.
Any player may pause the game at any time but other players may un-pause it after a delay of 30 seconds.
Any message boxes or events that would normally cause the game to pause automatically, depending on your
message settings, will display normally but will no longer pause the game. Some of these will expire if you
don’t respond to them, disappearing after a period of time. Others will disappear if they are no longer valid.

Tutorials

If you select the Tutorial button in the Launch Menu, you can play the HoI2 tutorials. For more details, see
the Tutorial section near the end of the manual.

Credits / Exit

Click on the Credits button in the Launch Menu to see a list of the many people involved in the design,

development, production and beta-testing of Hearts of Iron II - Doomsday. The Exit button will quit the game
and return you to your Windows desktop.

The General Interface

There are very few parts of the HoI2 interface that are visible at all times. The majority of your screen will
contain a display of context-sensitive information that will change depending on the type of action you are
taking. There is one area that never changes, located at the top of the screen. This provides a quick reference to
some of the most critical pieces of game information and also gives you access to all of the principal interfaces.
There are also a few other things that aren’t directly part of any other interface but have a global impact on the
game. Taken together, these are best described as “the General Interface”.

The Top Bar

This is the area at the very top of the screen that is visible at all times and displays a quick overview of the state
of your nation. It also gives you access to each of the main, vitally important, interface screens.

Status Overview

The upper portion of the bar shows a series of icons and values to which you will frequently refer. This allows
you to quickly review your reserves of energy, metal, rare materials, oil, supplies and cash. It also displays your
manpower pool, national dissent level, and your transport and industrial capacities. Hovering your mouse over
any of these will reveal an expanding tooltip that gives you a more detailed summary of that item, particularly
your daily income and expenditures. If the daily change is a negative one, then the value will be displayed in
red. Each item is described in detail in the relevant section of the manual.

The Folder Tabs

Immediately below the status overview is a set of clickable folder tabs that give you access to the six main
HoI2 interface screens, which we’ll later discuss one by one in the manual. Everything displayed below the top
bar depends on which of these folders you’ve selected.

• View Map: Clicking this folder tab displays the interface that you’ll use most often: the Main Map Folder.

This is used to view the map of the world where you’ll find details of your provinces, examine and issue
orders to your units, deploy new units, and perform most other common in-game actions.

• Intelligence: This is the Intelligence Folder, where you will recruit new spies, manage their activities, and

review whatever intelligence has been collected about other nations’ armed forces and capabilities.

• Technology: This is the Technology Folder, where you will assign specialized teams to begin working on

research projects, and where you may review already available technologies and their effects.

• Production: This tab displays the Production Folder, where you control your national budget, initiate the

construction of new units and industrial and defensive structures for your provinces, and see a summary of
such important things as your current trade agreements, convoys and resource depots.

• Diplomacy: This tab takes you to the Diplomacy Folder, where you may set your domestic policies, conduct

diplomacy with other nations, and view diplomatic and political information about the other nations in
the world.

• Statistics: This folder provides a set of detailed charts and pie charts, allowing you to view summaries of

HEARTS OF IRON DOOMSDAY

almost all of the important information about your nation, armed forces, and the rest of the world. There
are some very handy “redundant” interfaces on these pages that allow you to make a number of similar
adjustments very rapidly, and many items are hot-linked to allow you to quickly jump to a province or unit
on the Main Map without having to search for it or use one of the other methods of locating items.

The Date/Pause Button

The current date and time are displayed in a button at the bottom right of the top bar. The time shown always
reflects Greenwich Mean Time (GMT) and, depending on what portion of the map is presently displayed,
could be significantly different from the local time. If you click on this button, the game will pause for as long
as you wish. Clicking on it again will resume play. You can also press the pause button on your keyboard to
pause and resume. Right-clicking on the button will display a menu that allows you to quickly select a new
game speed, or to toggle between sprites and counters being displayed in the Main Map folder.

The Game Management Menu Button

Immediately to the right of the date/pause button is a button labelled “Menu”. Clicking this will bring up the
Game Management menu where you may select from several options:

• Save: Allows you to save your game in its current state. The default file name will be your country, date

and time, but you may change this to whatever you like by simply typing in a new name. Once the save is
complete, you will be returned to the game.

• Options: This brings up the in-game options submenu, which is similar to the new game options. Here,

you may change the game speed, toggle between sprite icons and counters, change your autosave settings,
and adjust your sound effects and music volumes. There is also a box at the bottom of this submenu which
allows you to change your message settings.

• Hints: This turns on the hint boxes that are displayed when the game first launches.

• Surrender: This ends your current game session (we all have to sleep sometime). Your current game data

is lost when you exit, so make sure you’ve saved first.

• Return: Returns to the game.

Message Boxes

You will receive many messages informing you of things that are happening during play. These may be
notifications of foreign diplomatic offers; they could be reports from your armed forces advising you that they
have engaged in battle or arrived at a destination; they might be reports from your scientists announcing a
new technology; or they could simply be an intelligence report about your own spies’ clandestine activities or
perhaps other international affairs that are common knowledge but may not seem to directly affect you.

Most messages can be displayed in several ways, and when you first install HoI2 these will initially be set
to certain defaults which you can later change to suit your preference. The most important ones will cause a
message box to appear on the screen and will pause the game until you have acknowledged it. Ones that are
somewhat less important will be displayed in a message box but will not pause the game. Others will display
a small message notification symbol at the right edge of the screen, waiting for you to open and respond to it.
Many of these have a time limit and will blink for a short while before disappearing. Messages that are prob­ably of only minor importance will simply be written to your history log. Those that are likely to be irrelevant
to you, such as a notice of a trade agreement being signed between two nations with whom you have no ties,
will not be displayed at all.

You can change most of your game’s message settings by clicking on the top bar’s Menu button, then clicking

22

2

HEARTS OF IRON DOOMSDAY

the Options button and then selecting the Message Settings button. This will display a scrollable list of mes­sage types that you can set to any one of the display options. You may also change the notification setting for
a particular type of message in-game without entering the submenu by right-clicking on the message when it
appears, even in the history log, and then selecting the new display mode from the options box.

Events

Hearts of Iron II also incorporates a special event system. These are usually historical events of great signifi­cance that have been programmed to occur during the course of your game and that can’t easily be modelled
using the regular game engine. In some cases, there are prerequisite conditions that must be met in order
for an event to trigger, and many of them have a degree of randomisation to make the exact date of their
occurrence somewhat unpredictable. There are also a variety of recurring random events that may have very
beneficial or possibly detrimental effects.

At first glance, an event box may look somewhat similar to a message box, but there are a couple of important
distinctions. An event will always display in a box, which cannot be changed via the message settings, and will
cause a single player game to pause until you have responded to it, should the event require a response;
multiplayer games will not pause in this fashion. Most events include explanatory text to give you some details
about their historical context. Many events will offer you more than one possible response and the effects of
most events are often quite significant, although the exact implications of a choice may be hidden in a few
instances. Events may also cause an additional event to trigger, possibly for you or for another nation. It is also
possible that an event will result in changes that couldn’t be achieved otherwise during the normal course of a
game, such as huge shifts of domestic policy or dramatic changes in public opinion. An event may also cause
certain officers or cabinet members to become available, or even to be removed from the game.

Read the text carefully and hover your mouse pointer over the available response options to see an expand­ing tooltip that describes the event effects. Once you have made your decision and clicked the appropriate
response, the message box will disappear and the game will resume.

Tool Tips

Hearts of Iron II has an extensive set of expanding tooltips that should greatly reduce your need to refer to
this manual, not to mention that it will usually provide the precise numerical details that I have intentionally
omitted from this text. Most tooltips are two-tiered. If you briefly hover your mouse pointer over an object, a
context-sensitive tooltip will appear. If you leave the pointer there for about three seconds, it is quite probable
that the tooltip will further expand to give you even more detailed information.

All numerical values displayed in tooltips will use current in-game data, almost always including any ap­plicable modifiers. Exceptions to this rule are typically due to “hidden” information of which you may not be
aware. For instance, a tooltip that comes up when hovering over an enemy force will only provide as much
information as your current intelligence and technology permits you to know and could be misleading if you
have not detected the entire force.

Right-Click Menus

Many items in the game, particularly those on the Main Map Interface Screen, have context-sensitive quick
menus that may be accessed by right-clicking on the province, sprite or item. Some also require that you hold
down the control (Ctrl) key as you do so. These act as shortcuts to commonly used controls or interfaces to
make it easier for you to manage various aspects of the game. In particular, you will use the right-click and Ctrl
+ right-click unit order menus on a regular basis to set and coordinate your military activities. I have tried to

HEARTS OF IRON DOOMSDAY

include an indication in this manual of every instance where these menus are available, but when in doubt, it
isn’t a bad idea to give it a try, since doing so will never cause the game to crash or malfunction.

The Main Map Folder

Overview

This is the default starting screen and the folder that you will use most often. It is here that you will view the
map of the world, see your troops and that of your your enemy, deploy your units, issue orders to your armed
forces, monitor ongoing battles, survey provincial defences and resources, and much, much more.

You can access the main map view by clicking on the
View Map folder tab on the Top Bar. The main map inter­face screen is divided into several important sections:

1. The Main Map: The largest area of the screen, this
is where you will see a portion of the world map
and be able to view and select your provinces and
units.

2 The Hot Buttons: This is a set of six buttons that give

you quick and convenient access to your provinces,
troops and deployment queue.

3 The Information Panel : The information displayed

in this area will change depending on what you
are doing. Most actions in the Main Map interface
involve viewing and often changing something in
this panel.

4 The Mini Map: This is a small clickable map that

displays the entire globe and gives an approximate
graphical representation of the current local time of
day. It can also be useful for locating your forces

5 The Mapmode Buttons: This is a set of ten small buttons that you will click to change the information

displayed on the main map. Some will cause a fairly drastic change of the map display, while others
act more as filters.

6 The History Log: This is a scrollable running log of game messages and events.

Since the main map and accompanying context-sensitive information panel places just about everything
you’ll need at your fingertips during the course of basic play, it is important to know how to navigate it, and
how to interpret the information you see there.

around the world.

Navigating The Main Map

The world is divided into more than 2500 individual provinces and sea zones. There are far too many to
be displayed on the main map while still giving you any useful graphical information, so the main map area
displays just one small part of the globe at a time.

Sometimes, you will want to view the main map at a very high level of magnification, where only a handful of
provinces will be visible, but where it’s easy to see and select your military units. At other times you may wish

2

2

HEARTS OF IRON DOOMSDAY

to get a less detailed “big picture” of what’s going on, where you can quickly survey several hundred provinces
or look at the general location of troops along a front or in a theatre. You can zoom in and out between HoI2’s
four different levels of map resolution by clicking on the small “+” and “-” buttons located on the right edge of
the Mini Map. You can also use the “+” and “-” keys on your keyboard; both the regular keys and the number
pad keys will work.

The Main Map can be scrolled by moving your mouse pointer to any of the edges of your screen. Doing so
will cause the map to begin scrolling in that direction until you remove the pointer from the map edge. You
can also use the Mini Map to quickly jump to a different area of the world by clicking on the part of the world
that you want to view. Another method is to use the Province Hot Button, the first of the six buttons, to jump to
one of your nation’s provinces. Simply click on the button, which has a small graphic of a map, and a scrollable
list of your provinces will appear in the information panel. Click on one of these to center the map on that
province. The next four hot buttons (see below) can also be used to jump to the location of a specific land, air
or naval force, or to a combat currently being fought.

Message boxes that appear during play will often include a “goto” button that you can click to take you quickly
to the relevant area of the map. If you know the name of the province you would like to go to, you can also
press the “?” button on your keyboard and type the name of the province into the box that appears on your
screen; remember, spelling is important! Many of the pages in the Statistics Folder include a “hyperlink” that
will take you directly to a province when you double-click on its name. That’s quite a few methods…and I’m
undoubtedly forgetting some!

Provinces

Each province - and most importantly, who controls it - is the basic unit of measure for victory in HoI2. There
is a distinction between “national” provinces, “owned” provinces and “occupied” provinces. National provinces
are ones that have historically belonged to a nation for a long period of time and where the population is
generally content with being part of that nation. The only time they will become upset with their government is
when it takes actions that are not popular in the view of the public. National provinces will be the heart of your
economy and provide you with the bulk of your military recruits. Owned provinces do not share this sense of
nationality, but have been under a nation’s dominion long enough that only very small pockets of resistance
remain to fight for independence. They tend to generate only a modest economic benefit to your nation and
are usually not inclined to join your armed forces. An occupied province is one that has only recently come
under the control of a nation, almost invariably as a result of a hostile action, and where the public not only
resents its new rulers, but will usually try to actively oppose them. These provinces tend to contribute very little
to your economy and are not suitable for recruiting purposes.

Not only can provinces contribute vital natural resources or industrial ca­pacity to your nation, but they can also provide additional defences or
strategic assets for your military. Even a quick glance at a province on the
main map will reveal important information about it, particularly in con­junction with several of the different map viewing modes. Clicking any­where within a province’s borders will change the display in the informa­tion panel on the left side of the screen to provide all the essential details
about the province. This is the Province Information Panel.

Province Name

Each province’s name appears on the Main Map and in the top left corner of the Province Information panel.

HEARTS OF IRON DOOMSDAY

Hovering your mouse over the province will also display a tooltip with its name, terrain, any special weather
conditions, as well as the name of the nation that owns it and controls it. In some mapmodes, the tooltip will
also identify the area and region to which the province belongs, which can be important when issuing certain
orders for your military.

Province Ownership and Control

The flag of the nation that owns the province appears just below its name in the information panel. You can
click on the flag to open the Diplomacy Folder with this nation pre-selected. If this province is currently occu­pied by another nation, then the flag of the controlling nation will be partially superimposed over the owning
nation’s flag. It is the controlling nation that receives any assets from a province.

Victory Point Value

The victory point value of the province, if any, is displayed as a number inside the star on the information
panel. National capitals are also identified by a red circle on the main map, and non-capital provinces of par­ticular strategic importance, also known as “key provinces”, will have a red star on them when viewed using
the victory point mapmode, and it should be noted that they will not be displayed in other mapmodes. If you
have captured most of an enemy nation’s key points, then it will be far more likely to accept your terms for its
surrender. If you control all of a nation’s key points, then you may impose extremely harsh terms if you wish,
including its annexation and removal from play.

Terrain

A province’s terrain is displayed in the picture on the information panel
and is also colour-coded on the main map when using the terrain map­mode. Terrain plays an important role in combat, affecting movement
rates and supply as well as the outcome of battles. The following are the
various terrain types:

• Plains: Depicted on the map in light beige, this type of terrain is
ideal for the movement of all types of units and has no modifying
effect on combat.

• Forest: Depicted in green, forest slows down the movement of all
units. Defenders gain bonuses in combat, and attacking units with
wheels or tracks will have additional penalties reflecting the extra
difficulty of manoeuvring.

• Hills: Hilly terrain is displayed in tan and slows down the movement
of all units. Defenders gain a small bonus, while attackers, particularly
units with wheels or tracks, incur a penalty. One specialised infantry
unit, the mountaineers, ignore these penalties.

• Mountain: Mountainous regions are displayed in grey and cause
a drastic reduction to movement speed. Defenders enjoy modest
bonuses in this terrain, while attacking units are heavily penalised,
particularly wheeled or tracked units. Only the special mountaineer
units are exempt from penalties, and defending mountaineers have

• Desert: Yellow regions indicate desert terrain. This terrain is simply not very pleasant to fight in. The
performance of both sides will be noticeably and fairly equally reduced, particularly in the case of cavalry
units.

very large bonuses.

2

2

HEARTS OF IRON DOOMSDAY

• Marsh: Marshes and swampland are depicted in pale green and, as you’d expect, can have a large impact
on the movement rates of wheeled or tracked units. Attackers suffer penalties, particularly motorised units,
while defenders enjoy a modest bonus. Special marine infantry divisions tend to operate better in these
conditions.

• Jungles: Displayed in dark green, jungle terrain is very poor for movement and ideal for defence. Any
attacking units that are not on foot will be nearly useless.

• Urban: Urban areas such as large cities are depicted in a yellowish-brown colour. Defenders usually enjoy a
modest advantage, since it is assumed that they have had the opportunity to select the optimum defensive
positions. Because of winding streets and a multitude of physical obstacles, infantry generally perform
better than other unit types in an urban area.

• Water: Lakes and sea zones are displayed in blue on the map. Clicking on them will display only limited
information, since they cannot be owned and no structures can be built in them. Note that for the purposes
of HoI2, the seaway between the Great Lakes and the Gulf of St. Lawrence is considered impassable to
naval and supply vessels, even though this wasn’t strictly the case historically. There are also several nar­row bodies of water that may only be used by your ships if you control the adjacent provinces (see Naval
Combat section).

• Rivers: Rivers are displayed on the main map as blue lines between provinces and will present a challenge
for military forces that attack across them. If possible, you should try to avoid launching such an assault
if there is an alternative avenue of approach, although having engineer brigades will mitigate this penalty
to a degree.

• Beaches: While many provinces have a coastline, not all of them are suitable sites for the landing of
an invasion force on the scale of HoI2. Landing forces from a naval transport, known as invasions, are
restricted to provinces that have an additional beach icon of a beige-coloured, crescent-shaped symbol
placed on the coastline. These operations are very tricky to accomplish and are quite risky if there is much
opposition to the attack.

Weather

Not only does terrain play a role in movement and combat, but weather and weather-related conditions
can also hamper your efforts. You can check the weather conditions using the Weather mapmode, and the
prevailing conditions are also indicated in the Province Details. Most of the effects will favour the defender
over the attacker, although both forces are usually penalized, and the degree of the effect is determined by
the severity of the conditions.

• Rain: This is shown on the weather map as a rain cloud. Land forces are only slightly affected by this

weather condition. Naval units will suffer somewhat greater penalties and have difficulty locating their
targets, and air units will lose almost all of their effectiveness.

• Storm: A storm is a severe form of rain and is shown as a rain cloud with occasional flashes of lightning.

Naval vessels are severely hindered in storms and land units will generally have a fairly tough time of it as
well. Air units cannot fly missions if their base is experiencing a storm and shouldn’t bother taking off if
these conditions exist over their target, since their drastically reduced performance will make the mission
little more than a waste of fuel.

• Muddy: This terrain condition is common in certain global regions and is shown in the weather mapmode

in brown, while unaffected provinces are shown in beige. This will only affect the performance of land
units, particularly any that rely on wheels or are extremely heavy, and unlike most other weather conditions
will very strongly favour the defenders in battle.

• Snow: Snowfall tends to affect attacking ground units slightly more than defenders, and will have a very

HEARTS OF IRON DOOMSDAY

negative impact on any air missions. Naval vessels will perform poorly as well.

• Blizzard: This is extremely heavy snowfall that will make your aerial units effectively useless, and will also
ground them if there is a blizzard over their air base. It has a significant impact on all land and naval
battles, as well as movement. Blizzards are displayed as very dense clouds with thick heavy snow falling
from them.

• Frozen: Regions will become frozen at certain times of year, reflecting extremely icy and hazardous condi-
tions that will affect movement but only slightly reduce combat capabilities. Defenders have only a slight
advantage on frozen ground.

Provincial Borders and Crossing Points

Regardless of the mapmode view you use, provincial borders are shown as a black-dashed line on the Main
Map, while national boundaries are traced with red lines. Rivers are depicted as blue lines along provincial
boundaries; there are some modest geographic liberties taken with river placement for game design reasons,
and only rivers of some significance are taken into consideration. Each provincial boundary is also listed on
the right side of the information panel when a province is selected, along with an indication of the type of
connection it has with its neighbour, though the label space is limited to the first six characters of the adjacent
province’s name. A green dash indicates a border that is not impeded. A blue river icon means that there is a
river that must be crossed to move across this border and, if contested by an enemy force, an attacker will incur
a river-crossing penalty (for more details, see the Combat section). If there is a unit engaged in battle in an
adjacent province, a small red “under fire” symbol will be displayed on the provincial boundary as well. If the
boundary is considered impassable, a red line will be displayed. Clicking on one of the border names or icons
will change the display to show the Province Details in the information panel for that province instead.

Some very narrow bodies of water may be traversed without the need for naval vessels and are shown using
a blue water icon in the boundary listing. Since these crossing points are not displayed on the Main Map, you
should pay careful attention to the province boundary listing whenever you are in a province that might have
one. If a hostile fleet occupies the sea area, it will prevent you from using or attacking across that narrow strait.
If the province you are moving to contains enemy forces, then the combat will be treated as an invasion and is
subject to the same penalties as a normal amphibious invasion (see the Combat section for details).

Provincial Assets

The area immediately below the province’s picture provides detailed information about each of its assets,
such as its natural resources, industrial conditions (factories, infrastructure and partisanship), its defences, and
any other provincial improvements that have been built there. These are described in detail elsewhere, so you
may encounter some terms here that you are unfamiliar with, and may need to refer back to after you have
read the other sections.

If the province you are viewing is currently controlled by your nation, then several of the areas will be shaded
grey and act as Quick Build buttons to allow you to initiate the construction of these items in the province. All
province assets may be built using the right-click province menu as well. For province infrastructure, factories,
land fortifications and naval fortifications, these are the only two ways to initiate their production. Other assets
are built by placing a Production Order for them. This is described in detail in the Production Folder section.

Manpower: This indicates the manpower that this province contributes to its controlling nation’s na­tional manpower pool. Manpower is needed for recruiting and reinforcing your armed forces, although

it may only be drawn from core national provinces and not from owned or occupied territories.

2

2

HEARTS OF IRON DOOMSDAY

Industrial Capacity (Factories): This is the number of factories that have been built in this province,
each of which provides industrial capacity for the controlling nation. New factories may only be built in

a province that has infrastructure over 33%.

Anti-Aircraft Batteries: This is a province defence that will fire upon any enemy aircraft that venture into

the province and do not need to be manned to be operational. This icon will also be visible in the main
map, as long as there is at least one AA battery present in the province. This is the only asset that may be built
using all three ordering methods.

Land Fortifications: This is a defensive structure that helps land forces repel enemy attacks that are

launched from adjacent provinces. Its size determines how effective a defence it is, but the fortifications
must be manned by land divisions and will not assist forces against sea invasions or paratrooper attacks. As
long as at least one fort is present, this icon is also displayed on the Main Map.

Coastal Fortifications: Similar to land fortifications, this is a defensive structure that helps land forces

repel an invasion that is launched from the sea. It must be manned to be effective, and it will not provide
assistance against attacks launched from a neighbouring province or paratrooper attacks. A matching icon will
appear on the Main Map, as long as there is at least a level one fortification.

Metal: The amount of metal drawn from the province on a daily basis. This amount may be increased

by researching appropriate industrial technologies and will either be placed in the nearest resource de­pot or, if a land supply route can be traced from this province to your capital, in your national stockpile. Metal
is needed by your factories to generate IC.

Energy: The amount of energy drawn from the province on a daily basis. This amount may be also in-

creased by researching the appropriate technologies and will either be placed in the nearest resource
depot or, if possible, in your national stockpile. Energy is essential to keep your factories operational and may
be converted into oil if necessary.

Oil: This is the amount of oil drawn from the province on a daily basis. It may be increased by research-

ing appropriate industrial technologies and will either be placed in the nearest resource depot or, if a
land supply route can be traced from this province to your capital, in your national stockpile. Oil is vital, as it is
consumed as “fuel” by many units in your military. If you run short of oil, energy may be converted into oil,
though the conversion rates may be poor until you have achieve a high technological level. The amount that
you may convert on a daily basis is limited to a percentage of your national industrial capacity.

Rare Materials: The amount of rare materials drawn from the province on a daily basis. As with the

other resources, this amount can be increased with appropriate technologies and will either be placed
in the nearest resource depot or, if possible, in your national stockpile. Your factories need a modest amount
of this resource to remain operational.

Infrastructure: The roads, railways and other infrastructure in a province. Unless this value is 33% or

higher, you will not be able to construct factories here and the more infrastructure present, the faster
some provincial assets may be built. Infrastructure has a very large effect on the supply efficiency and move­ment rate of troops located in a province and insufficient levels achieved through poor planning or destruction
by enemy bombing campaigns can have devastating results.

Partisan Activity: This is the amount of partisan activity in the province. Partisans will actively seek to

hamper your industry and supply in non-national territories and may even rise in revolt if the opportu­nity arises. You will need to assign forces to anti-partisan duties to suppress their resistance efforts; garrisons
and MPs are particularly good at this.

HEARTS OF IRON DOOMSDAY

Air Base: All air units must have a base of operations. The number of individual wings that may be sta-

tioned in a province without penalty is determined by the operational size of the base, which may be
reduced as a result of enemy attack. If too many wings make simultaneous use of a base, they will experience
reduced rates of repair and upgrade and will be slow to regain organisation. On the main map, a base will be
blue if it is being used by at least one wing and grey if it is not, although this colour distinction is hidden by the
fog of war.

Ports and Naval Bases: While many provinces have a large enough port for naval vessels to temporar-

ily dock, all military vessels require larger facilities for repairs and refitting to take place. A naval base may
support any number of flotillas, but the size of the base determines how efficiently it does so. Repairs to dam­aged ships will only occur when they return to their assigned naval base. This icon will appear in two different
sizes on the main map. A small icon indicates a port, while a larger icon indicates a naval base. If either is
coloured in blue, then the port or base currently contains naval vessels, although this too will be hidden by the
fog of war. A naval base in a province that you own will remove the fog of war from an adjacent sea area, al­though it may not necessarily detect any or all enemy naval vessels that go there, since this is subject to your
technology. Ports are not displayed in the Province Details, so if you see this icon in the information panel, it
denotes that a naval base has been built here and will also indicate its size and operational condition.

Radar Station: Radar stations provide improved detection of enemy air and naval activities. The air-to-air

combat abilities of any aircraft defending the skies over that province will be improved proportionally by
the size of the radar installation. A radar site also removes the fog of war from an adjacent sea zone, although
their detection of enemy forces in that zone is limited by the number of stations and by their technology level.
You will not be able to see another nation’s radar sites in any province that is hidden by the fog of war.

Nuclear Reactor: This installation might be better described as a nuclear test facility, since it does not

provide any power that can be used on a provincial level. Instead, its function is to greatly assist in the
research of nuclear technologies and accelerate the testing and manufacture of weapons-grade materials.
Nations tend to be secretive about such projects, so these will not be visible if the province is hidden from you
by the fog of war.

Rocket Test Facility: This is the rocketry counterpart to a nuclear reactor, providing a facility for more

rapid testing and manufacturing rocket-propelled devices such as flying bombs, rocket bombers, ballistic
missiles and ICBMs. As is the case with nuclear reactors, these are hidden by the fog of war.

Context-Sensitive Information

The upper half of the remainder of the information panel, the large slate-grey area, will display one of two
things depending on whether or not you control the province you are reviewing. If you don’t control it, then
some basic but essential diplomatic information will be displayed here, as well as the controlling nation’s flag.
You may click on the flag to initiate a diplomatic action with that country. If the province is currently under your
control, then a complete list of any land, air and sea units that are currently stationed here will be displayed.
You can click on one of these list items to select the unit, though this is only one of several ways to do so, and
then view its details and issue it orders.

Quick Build Buttons

If the province you are viewing is currently under your control, some of the provincial asset values will be
displayed in grey and will also act as Quick Build buttons that allow you to quickly issue a production order
for more of that item to be built in this province. For infrastructure, factories, land fortifications and naval
fortifications, this is one of only two ways to issue a production order. I will detail this in the Production Folder

0

1

HEARTS OF IRON DOOMSDAY

section of the manual and give only brief instructions here. Click on one of the Quick Build buttons to place
a production order for this item to be built in this province. You will see the production order appear in your
national Production Queue, which is displayed in the Production Folder, and this will also be displayed in the
lower portion of the information panel for this province. You may click on the Quick Build button a number of
times to order the serial production of multiple identical units.

Right-Click Province Menu

Right-clicking in the main map area of a province you own will display a menu of all possible province
improvements that may be built, allowing you to quickly initiate construction of these in exactly the same
way as using the above hot buttons mentioned above, and also allowing you to build some of the other
improvements that aren’t included as owned-province hot buttons. Right-clicking on another nation’s province
will display several context-sensitive options that you may select to quickly initiate a diplomatic or intelligence
action with that nation. Each of these is described in detail in the relevant portions of the manual.

The Hot Buttons

The six Main Map hot buttons provide a quick means of gaining an overview and location of your provinces
and armed forces. While details about combat and armed forces will be given in the Combat section, an
overview of each is given here.

The Province Hot Button

Clicking on the province hot button displays a list of all of your currently controlled provinces in the
information panel. This allows you to conduct a very fast survey of your nation’s resources and any

recent enemy activity. To the right of each province’s name is its current industrial capacity, an indi­cation of the type of resources that have been drawn from it, as well as its manpower value. If a battle is cur­rently being fought there, or if it has very recently been attacked by enemy bombers or naval bombardment,
then a red “battle” icon will appear adjacent to its name. To the left of each province is a small symbol that will
be green if the province is one of your owned provinces, or red if the province is normally owned by another
country but is currently under your occupation. Clicking on any of the small “header” icons at the top will sort
the list in descending order. You can click the Provinces header to return to an alphabetical sorting. Clicking on
the province name will center the main map on that province and display the Province Details in the informa­tion panel.

The Land Forces Hot Button

Clicking on this button will display a list of all provinces that currently contain your land forces in the

information panel, as well as basic information about the forces stationed there, including the

number of divisions, their overall strength and organization, and the portrait of their commanding
officer. If an army is presently carrying out orders that you have given it, a summary of the orders will be dis­played here, and if it is involved in an attack, the combat icon will appear adjacent to its current strength. You
may jump quickly to the province by clicking on the province’s name in the information panel, or you may
bring up details about any army by clicking on its name in the listing, also causing the main map to jump di­rectly to that province.

The Air Forces Hot Button

Click this hot button to display summary information about your air forces. Each of your provinces

containing an air base will be listed here. To the right of the base’s name are two values: the overall

size of the base and its current operational size. If an air base has been attacked by enemy bombers,

HEARTS OF IRON DOOMSDAY

the operational size may be less than the base size. As long as you devote IC to reinforcements, the base will
gradually be repaired and will become fully operational once more. There is no restriction to the number of air
wings that may be stationed at a base, but if this number exceeds the base’s current operational size, the rate
that units regain organisation, are repaired, or are upgraded will decrease. It is possible to base your air wings
in an ally’s air base, although you are subject to the same size restrictions, at which point the ally’s province will
also appear in this listing.

Your air units will be listed immediately below their current base assignment. You will see a unit’s current
mission and location (which may be different than its base if it is flying at the time that you review the informa­tion) as well as its leader, strength and organisation. This panel can also be used to quickly issue new orders
to your air forces by clicking the order box in the lower right corner of the unit’s listing and issuing new orders.
Click on a squadron’s name to jump to its location on the map and to review detailed information about its
composition.

The Naval Forces Hot Button

The Naval Forces hot button is very similar to the Air Forces hot button. Clicking it will bring up a
complete listing of your naval bases and the various units that have been assigned to each. The base

size and current operational status are shown beside the name of the port; note that naval bases
are subject to aerial attack. Naval units are listed below their base, along with a summary of their current loca­tion, orders, commanding officer, strength and organisation. Clicking on a unit will center it on the map, and
the information panel will display more detailed information about its components. Just as with the Air Forces
hot button, you may quickly issue new orders to your naval units from this panel.

The Active Combats Hot Button

When you engage in large-scale operations, it can be easy to lose track of all of the various combat

activities that are currently underway, even though you will receive a message when each one com-

mences. The Active Combats hot button becomes an invaluable tool for quickly locating and evalu­ating the status of any battle.

When you click this hot button, you will see a complete scrollable listing of all active military engagements.
Each will feature a summary of the size and nationality of the forces involved, the portraits of the two oppos­ing commanders, and a graphic representation that shows each force’s current strength and organisation.
The attacker is always listed on the left and the defender on the right. Below them is a battle status bar that
gives an approximate idea of who is currently prevailing. If you click on any of the active combats listed in the
panel, you will jump to the location in the main map and the Combat Details, a detailed battle analysis, will be
displayed in the information panel.

In very large wars, you may have a huge number of battles in progress, so you can also filter which active
combats are shown when you click the hot button. You may choose to see a list of only the land, air, naval, or
bombing engagements by clicking on the appropriate icon at the top of the listing. Click the “all” icon to return
to a complete listing of all active combats.

The Force Pool Hot Button

The sixth hot button is used to view and deploy new units from your force pool. I will give you de­tails of how to use this interface later in the manual so it will suffice to indicate here that if you click

on the Force Pool hot button, you will be given a list of all of the available units in your force pool.
These are the new units that you have built or recruited using the production interface which are ready for
active duty and are simply waiting for you to issue them an assignment. If you have given orders for the stra­tegic redeployment of a land unit then it will appear in this list as well, along with its intended new location.

HEARTS OF IRON DOOMSDAY

You can only review - not change - a strategic redeployment order, and the force is listed here only for your
reference and convenience. Important note: Each item awaiting deployment in the force pool will tie up na­tional transport capacity as well as consuming a daily allotment of supplies. This may hurt your ability to effi­ciently supply your forces that are already on the front lines. Items in the force pool will also have very poor
organisation when first deployed and will not be upgraded with the most recent technological advances until
they have been placed in the field.

The Mini Map and Mapmode Buttons

The Mini Map has three primary uses: If you left click anywhere on the Mini Map then the main map will
move to be centered on that location, making this a quick way to jump between theatres. The Mini Map also
has a graphic representation of the approximate local time of day for any portion of the globe. A dark band will
sweep across the Mini Map, indicating which global regions are currently experiencing night. The third function
of the map is accessed by right-clicking on the Mini Map and selecting the type of force you would like to view.
Small red dots will then appear on the Mini Map, showing you the locations of all forces of that type.

On the right edge of the Mini Map are small “+” and “-” but­tons. Clicking on these will change the magnification of the main
map. You can also use the “+” and “-” buttons on your keyboard
to do the same thing. HoI2 permits four different levels of main

below the Mini Map, is a series of ten Mapmode buttons that allow you to quickly change the main map view
to provide you with important and often essential information at a glance.

Terrain Mapmode

This is the standard display mode, with provinces shown colour-coded by terrain type (see the Provinces
section above for a description of each terrain type). Province improvement symbols are shown, but the por­tions of the map that are not within visual range of your alliance’s provinces or military units will be covered
by the fog of war.

Political Mapmode

While the unit and province improvement display remains the same as the terrain mapmode, this view
colour-codes all provinces to show the controlling nation instead of the terrain.

Weather Mapmode

Click this button to view the prevailing weather trends around the world. Provinces will be coloured beige
unless the conditions are muddy (brown) or frozen (white). Animated icons will show the current weather
trends in provinces and sea zones, indicating frequent rain, storms, snow or blizzards. If you’re planning a
major offensive, check this map before you launch it.

Economic Mapmode

This mapmode provides a quick means of checking resource locations and industrial capacity. Provinces
belonging to your nation are colour-coded in light green if they contain at least one factory, or in dark green if
they belong to you but do not contribute at all to your nation’s industrial capacity. Any province that has some
type of natural resource or manpower value will contain the appropriate icon to indicate its presence. You can
also find this information in the Territorial Information summary in the Statistics folder.

map magnification. Along the base of the information panel,

HEARTS OF IRON DOOMSDAY

Supply Mapmode

This mapmode displays military units and is therefore subject to the fog of war. Each province will be colour­coded to indicate whether it is currently within allied supply. If it is currently within supply, it will be shaded in
green, and if it lies outside of an allied supply chain it will be red. The shading of each province indicates its
approximate infrastructure level. Darker shadings indicate lower infrastructure levels and lighter shadings indi­cate excellent infrastructure. Note that enemy and neutral provinces that are adjacent to allied provinces will
also usually be displayed in green, since a unit that moves there would remain in supply. Sea zones through
which either supply convoys or resource convoys will run are also indicated on the map as a clear blue colour,
rather than the standard greenish-blue tint. This only indicates that the convoy path has been created, but does
not indicate that a sufficient number of vessels have been assigned to actually carry out that duty. Supply and
convoys will be discussed in detail in the Production and Combat sections.

Partisan Mapmode

This mapmode will give you a quick indication of the risk of partisan activity in your provinces. Green shading
indicates a province which has no risk of rebellion. Various shades of red indicate provinces where partisans
are active, with darker shading indicating greater levels of activity; these should be carefully monitored. A tool­tip details all current partisan-related conditions. Partisans are discussed in detail in the Diplomacy Section.

Region and Area Mapmode

The next two buttons will display a colour-coded map of either regions (large province groupings) or areas
(somewhat smaller subdivisions of the regions, usually about 3 or 4 provinces in size). Areas and regions
are used for many of the orders that you will give to your air force or navy and do not indicate ownership or
control, so you may find these modes convenient when issuing such orders.

Diplomatic Mapmode

It is easy to lose track of who is at war with whom and who is allied with whom, so this mapmode allows
you to determine this at a glance. The map display is colour-coded and context-sensitive. Click on a province
to view the world from its controlling nation’s perspective. A dark green province is currently controlled by
that nation. A national province will also have a red dot in it to indicate its importance. A light green province
belongs to one of that nation’s allies. A red province is currently controlled by another nation with which the
nation is at war.

Victory Points Mapmode

This mapmode can be used to quickly locate provinces that have an assigned victory point value. Green
shading indicates that a member of your alliance occupies the province; orange shading indicates that a
neutral country occupies it; and red shading means that it is currently controlled by an enemy. Provinces with
very high victory point values, often national capitals, will be darker in colour than those with lower point
values. Key provinces of particular strategic importance for peace negotiations are marked with a red star in
this mapmode.

The History Log

The history log is a scrollable sequential list of the messages and events you have had during the game. In
multiplayer mode, it will also record any chat messages you send or receive. You can scroll back up through
recent messages received during your current session of play, which is also saved as a log for future refer­ence. A full log may be read using the History Log screen in the Statistics folder. If you wish, you may hide
the message log by clicking the small button at the top left corner of the log and later restore it by clicking on
the button again.

HEARTS OF IRON DOOMSDAY

The Technology Folder

Overview

Although the Intelligence folder is the next tab on the top bar, we will discuss this a little later in the manual
(after the Diplomacy section) since the concepts and functions of both are interconnected. Instead, let’s move
on the Technology folder.

Technology is an integral component of Hearts of Iron II and your degree of overall achievement will have a
significant impact on many things. Your domestic affairs will benefit from new efficiencies in extraction, conver­sion and production rates, and your military will deploy new technologies to gain a crucial edge over your
enemies. You may even begin nuclear experimentation that can lead to powerful new energy sources…and
the atomic bomb.

Unlike most things in HoI2, this does not require a direct allocation of IC. New technological advances are
gained by hiring a team of scientists, assigning them a research project to work on, and then after a period of
time, the team will announce that it has achieved this new technology. The length of time will depend on the
nature of the project and on the skills and expertise of your team. You are also limited in the number of projects
you may work on simultaneously. The maximum number of projects and the specific teams that are available
to you will depend on which nation you are playing, and on your nation’s economic strength.

Research speeds may be further improved or hindered somewhat by several of your cabinet ministers.
Your rocketry research will be greatly aided if you have built rocket test facilities in at least one province, and
your nuclear research will benefit similarly from a nuclear reactor site. The only other way to accelerate your
research is to acquire blueprints from another nation. Gaining an edge over your enemy, or at very least main­taining an approximate technological parity, will almost certainly be vital to your overall success.

Selecting Research Teams

The left side (area 1) of the Technology Folder will display up to five teams of scientists, each of whom may
be assigned a project to work on. When you first start playing, this area will be empty, waiting for you to as­sign research teams to each slot and to give them each a project to pursue. Depending on the nation you are
playing, you may have as many as five slots, or as few as one. The number of available slots is based on your
nation’s current industrial capacity.

level, the less time the team will need to complete a project, but they will have a high daily financing cost. The
small colour-coded icons indicate the team’s areas of expertise, or fields of research at which the team excels.
The number of available teams and their skill and areas of expertise will depend on the country you select and
will rarely change during play.

Click on a blank team slot to display a list of the
teams in your nation’s pool. Some of these may
be headed by individuals, while others will be
identified as companies, though there are no
benefits or penalties to selecting one over the
other. Each team will have a skill level and will
have at least one area of expertise. The skill level
is an indication of the team’s overall proficiency
and will affect both the daily cost of funding the
team and the overall rate at which it will be able
to research a new project. The higher the skill

HEARTS OF IRON DOOMSDAY

Whenever possible, try to find a team that has expertise in the fields that relate directly to the components
of the project that you intend to assign them, even if they might be less skilled overall than another team that
lacks this expertise. Each area of expertise that matches a component’s field requirement will give the team
a research bonus when working on a project, so the more fields that match, the better. A lower skill level will
also result in a reduction in the daily cost of financing the team during the course of the project. Choosing an
appropriate team is most easily done by first selecting the project you intend the team to research (see next
section) and then scrolling through the list of available teams. If a team has an area of expertise that matches
one of the project’s requirements, the icon for that field will be highlighted in green. This will allow you to
rapidly find the most suitable match.

Once you have chosen a team by clicking on it, a portrait or logo will appear in the project slot of the technol­ogy folder and you’ll see the team’s name and its areas of expertise. If you haven’t yet assigned a project for it
to work on, you will also see a comment that it is idle and that it does not currently require funding. Idle teams
may be replaced by clicking the Replace button and selecting a new team. The new team will be placed in that
project slot and the old team will be returned to the team pool.

Research Projects

Selecting and Assigning a Project

Across the top of the screen (area 2) are a set of buttons listing the various general categories of technology
in HoI2. Each category has many individual projects, each of which has its own set of component advances.
When you click on one of the category buttons, the main section of the folder (area 3) will display a colour­coded flowchart of all of the projects that are part of that category. A dark green entry indicates that you have
already completed this project; light green indicates that you have all the prerequisite advances necessary to
begin researching the project; yellow indicates that a team has already begun work on the project; and red
indicates that you lack some of the prerequisite accomplishments to begin research. The arrows in the flow
chart indicate the prerequisites for each project, making it easy to see what steps must be taken if you are
looking far into your research future.

The various secret weapons fields are a special case. There are prerequisites in other categories that must first
be completed, and at some time shortly thereafter a special “event” will fire that will unlock one or more secret
weapon projects. Until the event has triggered, you will not be able to begin research on that project even if
you satisfy the technological requirements.

Clicking on any one of the projects will display the Project Details (area 4) and its component advances.
Each component will have a difficulty rating and a specified field that is the primary discipline that relates to
the component. The overall project completion time will be reduced for each of the assigned team’s areas of
expertise that correspond to one of the components’ primary fields, but a higher difficulty rating makes for
a longer research schedule for that component. You will also see a list of the benefits you may expect upon
completion of the project. The effects will vary significantly from project to project. Some improve an aspect of
your economy; others will increase the abilities of your military; and others will make new or improved units
available to you that a less advanced nation will not be able to use.

Each project has one other factor that can play a role in determining how long it will take to research: the
historical year that it appeared. This reflects the need for other sub-components that aren’t directly included
in the technology tree’s multitude of components but nevertheless played a historical role in making scientific
advances in this area possible. If you begin researching a project before its historical time period, it will take
longer to complete since your team will need to spend additional time inventing those hypothetical subcom­ponents. Highly complex or advanced projects may be very difficult and time-consuming to complete, and it is





HEARTS OF IRON DOOMSDAY

very unlikely that a nation will be able to complete research on all of them during the course of a single game.
In fact, for many nations, it will be nearly impossible to research everything.

Progression in advanced levels of rocketry research will be nearly impossible without the construction of
appropriate test facilities to assist your scientists. If you intend to pursue this field, you should build at least
one rocket test site as soon as you are able and then increase its size whenever possible. This province im­provement will drastically reduce your research times of further rocketry advances. The same is also true of
nuclear research projects, which will progress very slowly unless you have built a nuclear reactor in at least
one of your provinces.

As mentioned earlier, a research project will take much less time if you begin with a set of blueprints for
the project. It is highly unlikely that a nation will simply give blueprints to you, although you may be able to
negotiate a one-time trade if you make an attractive enough offer during your negotiations. Your spies can also
be ordered to infiltrate an enemy and attempt to steal a set of blueprints to a technology that you don’t yet
possess. This can be a risky operation, but the rewards can be substantial. A set of blueprints for an advanced
technology does not grant you knowledge of any prerequisite advances that you might lack, nor does it give
you any bonuses when researching them. The blueprints will only be of use to you when you have reached a
point where you would normally be able to begin work on that project.

Once you have decided on a project that your team is able to research, click the Start Project button to as­sign the team to this project. The main area of the screen will then change to display the project details with
an indication of the overall progress being made on the project. Money will be withdrawn from your national
cash reserves to finance the project and as time passes, you will be able to see the team gradually researching
each of the component advances. You will also see an indicator showing the overall progress being made on
the project. If you lack sufficient funds to continue financing the team’s work on the project, research progress
will slow dramatically, the team’s skill level will temporarily be set to zero, and a large red dollar sign will be
displayed as a warning. This penalty will be removed once the team’s financing has been restored.

After all of the components have been researched, the project will be complete and you will be notified that
the team has finished its task. Whatever effects the technology provides will be immediately available, though
in many cases this will require some degree of implementation.

Cancelling and Reassigning a Project

Only one team may be assigned to a project at any one time. Should you so choose, you may cancel the
project at any time and then assign it to a different team, or abandon it and start work on something else
instead, by clicking the Cancel Project button on the project details screen. You will lose all of your progress
towards this project including any components that have been completed and all cash invested, so this should
only be done under dire circumstances.

Implementing New Technology

The effects and implementation of a new technology will vary depending on the type of project and are far
too numerous to list here. Some effects are instantaneous and require no direct action or IC allocation since
they will be implemented immediately and automatically, while other projects may have little to no immediate
effects and act more as stepping-stones along the road to a major new technological breakthrough. Many mili­tary advances will be improvements to existing technology and any units you have in the field will need to be
upgraded to take advantage of the new benefits. There are many unit types and province improvements that
will not be available until you have researched the prerequisite technologies. This includes specialised infantry
units (mountaineers, marines, paratroopers, etc.), radar sites, nuclear weapons, and many of the heavier,
larger or more advanced tank, aircraft and ship designs. You can check all of this by consulting the details of

HEARTS OF IRON DOOMSDAY

the advances in the technology folder.

Upgrades to existing units are accomplished by allocating IC to the Upgrades slider in the Production folder.
Naval advances that result in a new model type cannot be upgraded, and in such instances you will have to
manufacture a new vessel to implement the advance. You will also have to decide whether to mothball the
obsolescent vessel to recoup its manpower, or to keep it in active service and benefit from the crew’s experi­ence.

Technology Summary

Clicking the Overview button at the extreme upper right of the category buttons will display a summary of
the effects of all the technologies you currently possess. This is where you can gain a rapid overview of the
most advanced unit types that are available, the benefits enjoyed by your nation’s industry, as well as all of
the mission types that you are able to order and how effectively your forces will be able to carry them out.
Remember that some units and mission types will not become available until you have researched the neces­sary technologies and/or doctrines. If you see a mission listed as “no” or a unit type without a model listing,
then you lack one of the prerequisite technologies. For such an innocuous little button, this sure packs a wallop
from a human player’s point of view. I urge you to review it frequently!

The Production Folder

Overview

The Production Folder is the interface you will probably use most frequently, other than the Main Map Folder.
It is used for two main purposes: issuing new requisition orders and managing your economy. It is here that
you will recruit new divisions, construct new aircraft and naval vessels, and build some of your provincial
assets. You will then be able to adjust the priority that each order is given by making changes to this in the pro­duction queue. It is also the folder you will use to manage your nation’s IC allocation to meet various domestic
and military needs and will manage the disposition of your network of convoys. Failing to pay attention to your
economy will have devastating effects that can cripple your nation, including the promotion of civic unrest and
shortages in the fuel and supplies your armed forces need to operate.

The screen is divided into two sections. The left side displays the Production Orders interface and the
Production Queue, while the right side shows the vitally important Industrial Capacity Allocation sliders, a
summary of your national resources, trade agreements and convoy activity, and the location and size of your
resource depots. We’ll look at each of these in turn.

Production Orders and the Production Queue

The Production Orders interface (area 1) and Production
Queue (area 2) are displayed on the left side of your screen
in the Production Folder. Every time you wish to recruit new
forces or construct one of several province assets, you will
initiate a new production order, confirm the type and quantity
desired, and then issue the order. It will then be added to the
bottom of the scrollable Production Queue listing, where you
may subsequently review, manage or cancel it. It is also pos­sible, and mandatory in some cases, to place orders for some





HEARTS OF IRON DOOMSDAY

province assets directly from the Province Details information panel, but the priority of those orders is man­aged from the Production Queue. Let’s look at all of these controls.

Placing a Production Order

Production Orders are easy to place in Hearts of Iron II. Begin by clicking one of the dozen or so production
category buttons on the Production Orders interface to indicate the type of item you wish to build. If an item
has prerequisite technological advances that you currently lack, the button will be greyed out on the interface
until your scientists have researched them. The Division, Air Wing, Flotilla and Brigade Attachment categories
will display a slightly different Order Details interface than the others, since there are a number of possible
items that you may select from each one. The remaining categories require no further selection and will display
a “simple” Order Details interface.

Orders for “simple” items are always manufactured using the most current technology, so there is only one
type you may build. Click on the name of the item you wish to build to display the Order Details interface. If
you wish to build only one unit, then you can click the Start Production button and the order will be placed
immediately. The Order Details interface will disappear and you will see that an order for one unit has been
added to the bottom of your Production Queue, though you may need to scroll down the list to see it. If you
want to order more than one unit, you may do so by adjusting the Serial Runs or Parallel Runs values. We’ll
come back to the meaning of and distinction between those options in a few moments.

Placing orders for divisions, brigade attachments,
air wings, and flotillas is slightly different since you
will usually have a variety of available unit types,
leaving you to choose which one to manufacture.
Begin by clicking on one of these four buttons in
the Production Orders interface to display the
more “complex” version of the Order Details in­terface. Scroll through the list of available unit
types (area 3) to locate the type of unit that you
would like to build. The length of the list and the
types of units available will depend on your cur­rent technology level. Since you aren’t expected

types and then mentally apply all of the additional modifiers that your current technology might give, detailed
unit information is displayed (in area 4) when you select a name from the unit type list. The meaning of each
of these is described in detail in the Combat section of the manual, so the only note I will add here is that the
organisation and morale values shown are not the maximum values, but rather the initial deployment values
of those items.

You will also want to refer to the cost of the unit and its required production time (area 6). All military units
require not only a daily allocation of IC during their production but also an initial amount of manpower to be
withdrawn from your national manpower pool. If you lack the manpower, you may still place the order and
it will be withdrawn as soon as it becomes available, although production of the item will not begin until the
manpower becomes available. This area will also indicate whether you already have some of this type of unit
under development and, if so, how many.

Once you have decided which unit to build, you may click the Start Production button to place an order

to be able to remember all of the various unit

HEARTS OF IRON DOOMSDAY

for one unit. If you wish to order multiple units, you may adjust the serial or parallel production run values
(area 5 - which we’ll discuss in a moment). Once you’ve confirmed your order, the Production Queue will be
updated to reflect this.

All order types have a daily IC requirement that must be maintained for production to proceed at full speed. If
you fail to allocate sufficient IC to production, the manufacture of items at the bottom of the Production Queue
will not begin until you increase your IC allocation, or items with a higher priority have been completed and
the IC that they were using becomes available.

Production Runs

The Order Details interface for both simple and complex orders will provide you with options to increase the
number of units produced in a production run (serial runs) and to place multiple identical production orders
at a time (parallel runs). This is designed to make the production interface as convenient to use as possible
when you want to manufacture large numbers of the same item or have ongoing, continuous production of
a certain thing. If you want to order very large numbers, you may hold down the “Shift” key as you adjust the
quantities, which will result in the increases being in increments of 5 units.

Increase the “serial runs” value of the Order Details will issue an order for multiple, identical items to be
manufactured sequentially. When you click the Start Production button, a single order entry will be added to
the Production Queue and your factories will begin to manufacture the first unit. When production is complete,
the unit will be added to your Force Pool and your factories will then begin manufacturing the second unit.
This process will continue, with the units becoming available one by one, until your order has been filled. If
you look at the order in the Production Queue after it has been placed, you will see the total number of units
ordered as well as which of those units is currently being manufactured.

Increasing the “parallel runs” value will issue a series of identical orders and each of the units will be manu­factured at the same time. This is a quick way of placing multiple identical orders without being forced to go
through the order procedure multiple times. When you click the Start Production button, the number of
orders added to the Production Queue will be the same as the number of parallel runs you have specified in
the Order Details. If you allocate sufficient IC to production, all of the units will be manufactured simultane­ously and become available on the same date. If you use both of these controls, you will issue multiple serial
production run orders, each calling for the same number of units per run.

There are obvious advantages and disadvantages to both approaches of issuing an order for multiple units,
and a hidden one as well. Serial orders take much longer to fill but spread out the drain on manpower which,
if required, will only be subtracted as each new unit is begun. They also require a small allocation of IC, since
only one unit is being made at a time. Parallel orders will rapidly deplete your manpower, if needed, and
demand much larger IC commitments, but multiple units will be available far sooner. Serial orders for military
units are not updated as new technological advances are discovered, even for units whose production begins
after the advance has been gained, so you may find yourself being forced to upgrade or even consider dis­banding them immediately after they are deployed. Although the same is true for parallel orders, it is far less
likely to happen during the shorter time period involved. There is one huge advantage, though, that applies
only to serial orders: the gearing bonus.

The Gearing Bonus

In the “real world”, there are significant manufacturing benefits to be gained from dedicated production lines
and other efficiencies of scale. I won’t go into the underlying economic principles as there are volumes on the
subject, many of them dating from the WWII era. The heart of the idea is that if a factory or series of factories
sets up a dedicated production line and can purchase its raw materials based on a high volume of consump­tion, then the overall cost of production and length of time it takes to make each unit will decrease. In Hearts of

0

1

HEARTS OF IRON DOOMSDAY

Iron II, this is represented by something called the “gearing bonus.” To avoid making the gearing bonus unduly
complex or excessively open to player exploitation, HoI2 takes a few small liberties in the way it is implemented
and awarded. Let’s get straight to the bottom line (and please pardon the pun).

If you place a serial run Production Order - one that calls for multiple units to be manufactured in a single pro­duction run - then you will be eligible to receive a gearing bonus where each successive unit that is produced
will require slightly less time to manufacture. The first unit will take the usual length of time and require the full
allocation of IC. The next unit will require slightly less time to produce and thus a lower total IC consumption,
and the subsequent unit will require even less time. Until the order has been cancelled or completed, each
unit that you manufacture will receive a gearing bonus that increases as each is produced. There is a maximum
bonus level, though, beyond which there will be no further reductions in time.

Note, however, that if at any time during the production run there is insufficient manpower in the national
pool or insufficient allocation of IC to a serial run order, the order will not only be put on hold but the gear­ing bonus will also reset to treat the current item as though it was the first one being produced. You should
consider giving serial run orders a very high priority in your queue to avoid having this happen. Note also that
provincial assets, no matter which method of ordering them you use, do not benefit from serial run gearing
bonuses.

Building Provincial Assets and Using the “Quick Orders” Buttons

Provincial assets are the wide variety of structures that can be built to make your provinces more economi­cally productive, more defensible, or to provide an additional boost to your research in the fields of rocketry
or nuclear science. Depending on the item involved, there are three possible ways that it may be ordered,
although in most cases only two of those options will be available to you. The exception to that rule is the AA
battery, which may use all three methods.

Infrastructure, factories, land fortifications and coastal fortifications must have a province location specified at
the time that the initial order is placed for their construction. You may do this either by selecting the desired
province and then using the appropriate Quick Build button in the Province Details display, or by right-clicking
on the province on the main map and selecting the asset you wish to build. Using either method will initiate
a new production order for that item, adding it to the listing at the bottom of the Province Details information
panel, as well as to the Production Queue. If you subsequently order additional items using either method,
they will be added to your original order. All orders for these items are serial orders. The level of infrastructure
in a province will greatly affect the length of time each of these assets takes to produce, and completed assets
will automatically be deployed to the province.

All other assets may be ordered using the right-click method or by placing a simple Production Order as
described earlier in this section. The order will then be listed in the Production Queue while it is being manu­factured. If you use the right-click method, the asset will automatically deploy to the province upon completion
(which I find very convenient!). If you use the Production Order method then the asset will be “sent” to your
Force Pool to await deployment instead (see below). It will then force you to spend a bit of extra time placing
them later, but it gives you an added degree of flexibility in their location and construction.

The Production Queue

The Produc-

to quickly review and manage your current production orders. Each time you place a new order, an entry will
be added to the queue’s scrollable list. On the right side of the entry, you will see some basic details about the
unit being produced as well as an icon that shows its type and a listing of its name and basic attack and defence

tion Queue

HEARTS OF IRON DOOMSDAY

values. If you used the quick order method to requisition a provincial asset, the auto-deployment location will
be identified as well.

On the left side of each line’s entry is the estimated date and time that the unit will be ready for deployment.
Below this is the “production percentage” value, indicating whether production of this item is proceeding at full
speed, which I’ll come back to in a moment. Towards the middle of the line you will see the daily IC require­ment of the project. If you have placed an order for a production run (a serial order), you will also see two
numbers below this. The first is the number of units from this order that have already been completed, and
the second is the total number of units ordered in the production run. Each entry also has a set of four buttons
that allow you to adjust the order’s priority, and Cancel Development button (an “X”).

Manufacturing new items requires an allocation of IC to their production and many items will also require a
one-time “consumption” of manpower from your national pool. While you can still place an order for an item
that you can’t afford, its manufacture will not begin until sufficient manpower and resources become available.
Both are allocated on a priority basis in the queue, which is always sorted in order of priority, so the orders at
the top of the list will always be allocated to and manufactured first.

You can review an order’s status by looking at its production percentage. If this value is 100%, then production
is proceeding normally and you can expect it to be ready on its reported ETA date, unless something like a drop
in available IC happens to affect it in the interim. If it is less than this, production is being delayed either by a
lack of necessary IC or by insufficient manpower. Any order that isn’t at 100% production will be colour-coded
in yellow or orange to make it easy to spot when scanning the Production Queue. Yellow means that produc­tion is only proceeding at a partial rate, while orange indicates that production has halted.

Manpower is not only consumed by production orders, but is also withdrawn from your national pool when
units that have sustained casualties are being reinforced. If you lack the manpower for a new production order,
you have four alternatives. You can simply wait until you have enough manpower in your pool, at which point
the available manpower will be withdrawn automatically and production will begin. Increasing its priority in the
queue will ensure that it will receive the manpower sooner. A second option is to cancel the order by clicking
the “X” button and placing the order again once you have enough manpower in the national pool. Since man­power is withdrawn when an order is first placed, you may have other orders that are higher in the queue for
which you’ve already paid the required manpower cost. Cancelling one of these will return the full manpower
value of the order to your pool which will then be automatically applied to the next order in the queue that is
waiting for manpower. Your final option is to disband some of the units you have in the field. This places their
manpower back into the pool, but they will lose any combat experience that they have earned.

Shortfalls in IC allocation can be dealt with in a variety of ways. The simple one is to allocate more IC to pro­duction, but this will take that IC away from something else, so this may not necessarily be a viable solution.
Building more factories in your provinces will increase the total potential IC if you are suffering from a lack of
capacity and have lots of resource reserves, while finding additional sources of natural resources will increase
the actual IC if you have enough factories but they aren’t operating at full capacity due to a lack of resources.
Technological advances may enhance your factories’ IC or improve your resource extraction and conversion
rates so you might want to look at this as an alternative. Your remaining option is to change the priority of your
orders to ensure that the ones you need most are produced first, and that lower priority orders are put on the
back burner until you have an excess of IC.

The IC that you’ve allocated to production is assigned to orders based on their priority, or their position in
the queue. Orders at the top of the production queue have the highest priority and will get any new IC that
becomes available. If you cancel one or more of the orders that are currently running at a 100% production
rate, then you will lose any IC and hence the resources that have already been used by the order, leaving the

2



HEARTS OF IRON DOOMSDAY

IC to become available to the next order in the queue. You should avoid doing this too often since it wastes
valuable resources and you could lose any gearing bonuses on that order. Fortunately, there is another solu­tion: changing the priority of an order.

Click on an order’s “prioritise” buttons to assign it a new priority in the queue. Moving it to the top will ensure
that it receives any available IC and begins production immediately; however, this will also cause your other
orders to be bumped downwards in priority and will result in at least one of your other orders now stopping or
slowing in production. Any degree of progress that this bumped order has received to date will be saved and
included once production resumes, but any gearing bonus that an order is receiving will be forfeited. You may
also send an order to the bottom of the queue if it isn’t particularly urgent, or you may shuffle its position by
making smaller adjustments to move it up or down one position relative to the other orders.

Once the production of an order is complete, the order will be removed from the Production Queue and
the newly built item will appear in the Deployment Queue. If you used the quick order method for a province
improvement, it will be deployed automatically to the province instead of to the Deployment Queue. The IC
that the order was using will be applied to the next order in the queue that is currently running at less than
100% capacity. Note that if you allocate more IC to production than is currently required to fill your orders, the
excess capacity will not be used and no resources will be consumed.

Two final notes about the Production Queue: At the beginning of some games, you may discover that there
are some items already in the queue and that they require no IC allocation. This is completely normal and is
because they have been “prepaid” for you as a special bonus in the scenario’s design. The other important
note is that the IC allocation in the Production Queue and in all other information displays in the Production
Folder is only updated at midnight each day. If you are placing sizeable orders, be sure to check back once a
new day has begun.

Deploying Unassigned Provincial Assets

If you placed an order for certain province assets using the simple Production Orders method, you will
need to deploy them from the force pool once production is complete. All other province asset orders will be
deployed automatically to whatever province you have already chosen to build them in. In all cases, choose
the location carefully because provincial improvements can’t be moved after they’ve been deployed and are
vulnerable to bombardment and capture. Building up industry that is within easy striking range of enemy
bombers will likely be a waste of assets, and there is often very little point in heavily fortifying a province that
is many miles away from any likely front.

Deploying a new provincial asset is quite simple. Click on the View Map folder tab and then click on the Force
Pool hot button. This will display a list of any assets and military units that have not yet been deployed. Scroll
through the list until you see the provincial asset that you wish to deploy, then click on it. The provinces on
the main map change to a colour-coding view as soon as you do this, with green indicating that the asset can
be placed in this province. Click anywhere in one of the valid provinces and the asset will be deployed there.
Invalid locations will be ones that don’t belong to you, are already at maximum capacity, or that are completely
cut off from your capital.

Deploying Military Forces and Rockets

The deployment of new military forces and rockets is similar to the method used for province improvements,
but there are some additional options and restrictions. Please see the Combat section of the manual for
instructions on how to do this. Military forces will tie up some of your transport capacity until you deploy them
so you should usually try to do so as soon as you possibly can.

HEARTS OF IRON DOOMSDAY

National Resources

We now turn our attention to the right half of the Production Folder and will begin with the information
displayed in the upper left portion of that side of the screen: a summary of your national resources. The data
that you see displayed in the national resources area of the production screen reflects your current stockpile or
pool of each resource type, with the daily change to this value displayed in brackets. This is the same informa­tion that you can view on the top bar but saves you the trouble of using the expanding tooltips to see the daily
rate of change for each. The information displayed is updated ever day at midnight, with the exception of the
supplies stockpile, which is updated hourly, and the manpower pool which updated as soon as manpower is
used to order a new unit and also drawn from daily for any necessary reinforcements.

It is also important to note that the values reflect only your national stockpile
levels and do not include any resources that might be located at your depots. The
daily change values indicate the rate of change to the national stockpile, so the
figure you see displayed reflects any transfers that you are making to and from
your depots, and any trade agreements that you might have in place. If this is
being impeded or otherwise affected by enemy convoy raiding or a shortage of
transports, then the values may not reflect your potential rates of change or any
changes to your depot levels. This can be a fairly important consideration that
many new players overlook.

Oil

Oil is available in the form of natural petroleum reserves and can only be found
in a limited number of locations throughout the world, predominantly the south­central USA, Colombia, Caucasus and parts of the Middle East. Historically, it was

shale”, etc.), which is represented in HoI2 by the ability to convert energy resources into oil. This will be done
automatically if your stockpile of oil is low, but the amount that may be converted is based on your national
IC level and your technology. Only a small amount of energy, determined as a percentage of your national IC
value, may be transformed into oil on a daily basis, and the conversion rate you achieve will vary depending
on the advances you have researched. At the beginning of the game, this will be very poor but will improve
steadily as your scientists discover new methods of refining synthetic oil.

Oil is the fuel that powers your naval vessels, aircraft, and any other military units that are motorised (tanks,
mechanised infantry, etc.). If you lack the oil to supply them, these units will grind almost to a halt, incurring
large reductions to their movement rates and causing them to suffer large operational penalties in combat
such as a reduced organisation value. You can see a unit’s daily oil requirements by viewing the unit details
and looking at the “fuel consumption” value. Land units consume only half this amount if they are stationary
and aren’t involved in combat. Aircraft and ships that are “resting” at their assigned base will consume only a
tiny fraction of the oil they require when they are engaged in military operations.

Metal

This resource represents a variety of common metals, with iron ore being the predominant one. The largest
global reserves are found in Sweden, China, England, Japan, Ukraine, and the mid-west and south-west USA,
although additional sources are scattered throughout the world. Certain technological advances can improve
your extraction rates.

Metal is used by your factories on a daily basis and is thus a mandatory component for generating industrial





HEARTS OF IRON DOOMSDAY

capacity. One unit of realised IC consumes one unit of metal every day, and failure to have sufficient supply in
your national reserve will effectively limit manufacturing to your daily rate of intake.

IC Production

Though mentioned in several places in the manual, the formula for base IC production is:
1 IC = 2 energy + 1 metal + _ Rare Materials
The actual value available will be this base IC amount as modified by current technologies.

Energy

The energy resource represents a number of different materials that are used to generate the power that
your factories require to operate. Historically, this predominantly came from coal fire generation as well as
hydro-electric facilities, wood-burning plants, and several other sources. While this resource is well distributed
throughout the globe, the greatest concentrations may be found in Germany, England, and parts of North
America. Energy may also be converted into oil if your stockpile of the latter is low, although the rate of this
conversion will be poor unless your scientists have discovered improved methods of synthesis.

Your factories will demand a healthy supply of power, each one consuming two units of energy for every
unit of IC that it produces daily. As with metal, a lack of energy will reduce production to the level of your
daily intake.

Rare Materials

This might be thought of as HoI2’s “catch-all” for materials that were consumed on a daily basis but don’t
belong to the metal or power categories. These are natural resources or materials derived or synthesised from
natural reserves that are relatively rare or were consumed only in limited quantities. Examples might include
rubber, sulphates, gold, potash, and other such resources and may be found scattered here and there around
the globe.

Rare materials were used for various components in a large number of manufacturing processes during this
era and a reasonable supply will be vital to keep your factories running. Each factory will consume one unit of
rare materials for every two units of IC it produces.

Supplies

Supplies aren’t a natural resource that you will find lying around in a province. Instead, these are manufac­tured by allocating IC to the production of basic allotments of food and ammunition that your military forces
will need to survive. Each unit has different requirements, which can be seen by referring to the unit details’
supply consumption rate, and failure to meet these needs will result in very poor organisation values, plum­meting morale, and a high rate of attrition. Also, your domestic population will become upset if you are failing
to supply your forces, resulting in an increase in dissent. Although the details are presented later in the manual,
I’ll remind you here that simply having supplies does not ensure that they will reach your troops. You will need
to establish supply chains for that purpose and have sufficient transport capacity and infrastructure to ship
goods along them. Unlike fuel, supplies are always consumed at their full daily rate.

Money

This is cold hard cash…and it doesn’t grow on trees. Fortunately, there are several ways of increasing your
cash reserves. Any IC allocated to the manufacture of consumer goods will generate some amount of money,
and excess allocations are treated as a surplus and converted directly into cash. You may also receive money as
part of a diplomatic transaction when you negotiate either a one-time exchange or a trade agreement.

HEARTS OF IRON DOOMSDAY

Money’s three most crucial functions in your nation are to finance projects for your research teams, to hire
spies and pay for their missions, and for the multitude of diplomatic actions that have a cash cost associated
with them. Money may also be used during negotiations with other nations to purchase raw materials or sup­plies. If you have no national cash reserve, your technological progress will grind to a halt and there will be
many common intelligence operations and diplomatic options that you won’t be able to initiate.

Manpower

Manpower is a resource that is treated somewhat differently than the others. Reviewing the main map while
using the economic mapmode filter will display a variety of provinces that have a large enough population to
contribute manpower to your national pool on a daily basis. They will continue to do so until the maximum size
of the pool has been reached, with the pool also being based on the total manpower values of your provinces.
At that point, your national pool will remain constant until you draw from it either for the production of new
armed forces units or for reinforcements to replenish casualties due to combat or attrition.

Partisan and Occupation Effects on Resources and Industrial Capacity

Captive populations are reluctant workers at best, so even if you are able to prevent outright rebellion, you
should not expect the workers in owned or occupied provinces to be as productive as those who are full­fledged citizens of your nation. Owned and occupied provinces are both subject to heavy penalties to the
extraction of oil, metal, energy and rare materials from their soil (occupied province more so than owned
provinces), and these same penalties are applied to their industrial capacity. This may be modified by your
domestic policies and cabinet, and will also be affected by the efforts of partisans who will further reduce
provincial IC by the degree of their activities, unless your forces are able to suppress them. The populations of
non-national provinces do not serve in your armed forces except under very unusual circumstances and thus
any manpower values in those territories will not be added to your manpower pool. An occupied province also
reduces your transport capacity, which we’ll discuss shortly.

Industrial Capacity (IC) and IC Allocation

To the right of the National Resources summary is one of the
most important interfaces in the game: the Industrial Capacity
Allocation sliders. These are used to allocate your available indus­trial capacity to the five main areas of production, effectively con­trolling your economy.

At the top of this area are three values: your current unused IC,
your available IC, and your base IC. The base amount is simple
sum of all the factories that are in your nation. During wartime,
this amount may be reduced if your enemy conducts a bomb­ing campaign against your factories. It is important to remember
that occupied provinces contribute less than their full IC to your
economy. The available IC reflects the actual daily IC production
which is the base amount, modified by your ministers, domestic
policies and any technological bonuses you might have. If you
lack sufficient natural resources, the available IC will plummet.
Partisans also have a direct effect on available IC, with every

output by that amount. The unused IC value indicates that you are allocating more IC than necessary to at

percentage point of partisanship reducing a province’s industrial





HEARTS OF IRON DOOMSDAY

least one area of production. Having some amount of unused IC isn’t such a bad idea, because this excess IC
allocation is “ignored” for the purposes of consuming resources and provides a buffer against small fluctua­tions of your nation’s total IC production. This can be particularly important in multiplayer games where you
may have only limited time to fine-tune your allocation levels and can benefit from having this “slush fund” of
IC to temporarily offset losses until you have time to attend to them. It also allows you to conserve resources,
saving them for occasions when you really need them.

Each slider displays your current daily IC allocation to this area at its right end. Immediately above the slider
is the amount of IC that you need to allocate in order to meet your current needs. The sliders can be adjusted
by either clicking on the “+” or “-” buttons at either end (usually used for small changes) or by dragging the
indicator tab (for larger changes). Holding down the “Shift” key when clicking a button will move the slider in
a bigger step, and holding down the “Ctrl” key will make the step even larger. The sliders are always zero-sum,
so adjusting one in one direction will cause all others to adjust slightly in the opposite direction to compensate.
You can lock a slider in place to prevent it from moving when you adjust other sliders, which is very handy for
ensuring that you don’t accidentally under-allocate a slider, but you should note that if you have locked all but
one slider, you will not be able to adjust it without unlocking at least one more.

IC SLIDER LOCK

You can lock an IC allocation slider to prevent it from moving when you adjust other sliders.
Right-click or double-click on a slider to lock it, and do so again to unlock it once more.

Consumer Goods

You will need to allocate some of your industrial capacity to the manufacture of consumer goods - the various
basic commodities that your population consumes on a daily basis - and you should expect your public to
become quite upset if you fail to provide for their needs. While their demands will vary depending on your
domestic policies, your cabinet ministers, and whether you’re at war or not, failing to allocate sufficient IC to
this area will cause national dissent to rise. Dissent will reduce the performance of your military and at higher
levels it makes your nation more susceptible to foreign coup attempts and may even lead to open rebellion in
your provinces. If you allocate excess IC to consumer goods, your national dissent will gradually diminish.

Allocations to this slider also generate cash revenue. You will need that money to fund your research projects
and for many of your diplomatic and intelligence activities, so some excess allocation may be needed unless
you are selling resources to another nation and earning enough money that way.

Production

The production slider is used to allocate IC towards the manufacture of the orders in your Production Queue.
Allocation shortfalls will result in low priority orders being placed on hold until new IC becomes available and
could result in the loss of the gearing bonus for an order. Excess allocation of IC to production is ignored and
is displayed in the summary as “unused IC”. Remember: unused IC does not consume resources, so this
is an excellent means of conserving those valuable resources until you need them and for guarding against
unexpected fluctuations that may result from enemy bombing campaigns against your industrial base.

Supplies

As mentioned earlier, it is vital to ensure that you are supplying your military with a daily allotment of food
and ammunition. This is withdrawn from your national stockpile of supplies and sent out to them along your
supply chains. You can trade for supplies with other nations, but it is usually far more efficient to allocate IC
to their manufacture. Whatever quantities you manufacture will be added to your national stockpile at a rate

HEARTS OF IRON DOOMSDAY

of three units of supplies for every unit of IC that you allocate. Be warned, however: having supplies in your
national stockpile doesn’t mean that your armed forces will receive those supplies. The delivery of supplies
depends entirely on whether your supply chains are intact and unimpeded, and on supply efficiency in the
provinces where your forces are located. Failure to supply your forces will seriously hamper their combat ability
and will result in an increase in dissent throughout your nation. This slider’s sole function is to manufacture
and stockpile the necessary materials.

Reinforcements

This slider allocates industrial capacity to reinforcements and repairs. It is used to train replacements and
repair equipment for units whose strength has been reduced as a result of combat or attrition. Military forces
have a “human” component as well, so as you are reinforcing them you will also need to have sufficient man­power available in your national manpower pool to be withdrawn to meet those requirements. The necessary
amount depends on the original manpower cost of the unit and on the percentage of strength that it has lost.
This slider is also used to rebuild and repair any provincial assets (infrastructure, factories, bases, etc.) that have
been damaged as a result of enemy bombardment. Failing to allocate sufficient IC to the reinforcement slider
will reduce the rate at which all of these replenishments occur, while any excess allocations will be ignored and
included in your unused IC total, thus also conserving natural resources.

Upgrades

As you gain new military technologies, you will be able to upgrade the abilities of your existing land and air
units as well as the air groups attached to your carriers (note that naval vessels cannot be upgraded.) This
is done by allocating IC to the upgrades slider and will frequently require a prolonged investment of up to
several months to complete. Your forces will continue to operate normally at their old combat values during
this time. Insufficient allocation will increase the length of time that this upgrade will require, while excess
investment is ignored and added to your unused IC total. Air units only upgrade during the times when they
are idle and at their assigned home base, and if too many units are assigned to the same air base, this process
will take far longer.

Automating IC Allocation

Just below the sliders is a button labelled “Auto Control Window”. Clicking this button displays a sub-menu
that allows you to delegate the management of your IC allocation sliders to your AI-controlled ministers. If you
wish, you may indicate a particular area that should be optimised if you lack sufficient IC to satisfy all of your
needs. Your ministers will then take care of fine-tuning your economy on a daily basis; however, if you have
manually locked a slider,your ministers will leave it exactly where it is regardless of any shortfalls or excesses
that might result. This same submenu allows you to automate trade, which we’ll discuss shortly.

National Transport Capacity (TC)

Although your nation’s transport capacity (TC) is not displayed directly in the production folder, this is
something that is fully dependent on your nation’s Industrial Capacity. Transport capacity is an abstraction
that Hearts of Iron II uses to represent your country’s overall ability to move men, equipment and supplies
throughout each nation. It is the underlying factor that will determine whether you can get the necessary sup­plies, reinforcements and technological upgrades to your armed forces in a timely manner.

The Top Bar will always display your nation’s transport capacity and how much of it is being used. The base
amount of TC is determined by your national IC output and can be increased by researching certain technolo­gies. This total value indicates the limit of your ability to move “stuff” such as supplies, fuel, and divisions that
are either in your force pool or are being strategically redeployed. If your required TC exceeds your available





HEARTS OF IRON DOOMSDAY

TC, your ability to carry out this vital task will be reduced and your troops will move more slowly, possibly even
beginning to starve unless they are in a very favourable location. We’ll look at this again in detail when we
discuss supply and supply efficiency in the Combat section.

International Trade Summary

The method of establishing new international
trade agreements is discussed in detail in the Di­plomacy section. The Production folder also in-

since they will impact on your flow of resources. Each line item identifies the trading nation, the type of goods
being exchanged, and the current trade efficiency. Hovering your mouse over any item in this scrollable list
allows you to view the precise details of the agreement. International trade does not use convoys to transport
the goods back and forth. Instead, this is abstracted to “invisible” commercial shipping that will attempt to
ensure that the goods reach their destination. These vessels are subject to enemy disruption if either nation is
currently at war with a nation that has a navy. Any enemy vessels that are assigned to convoy raiding will auto­matically disrupt and sink some percentage of the trade goods being exchanged, resulting in a reduction of
trade efficiency. You will see a percentage value displayed at the right edge of each trade entry that indicates
the current trade efficiency. If it becomes impossible to establish a direct link with your trading partner, al­though this may be traced through friendly territory, your trade efficiency will drop to zero. Goods will con­tinue to be shipped, even though they won’t arrive at their intended destination, until one of the trading
partners cancels the agreement.

You may cancel a trade agreement by right-clicking on its listing in the trade summary and then confirming
that you wish to cancel it. You may also cancel an agreement in the Diplomacy Folder by selecting the nation,
then using the “Cancel Trade Agreement” diplomatic option and specifying the agreement to cancel.

Automating Trade

Clicking the button labelled “Auto Control Window” (the same one mentioned above for automating IC al­location) allows you to have your AI-controlled ministers manage international trade for you. You can instruct
them to initiate trade with other countries to import sufficient quantities of any raw materials you lack and
you can allow them to respond to other nations’ trade overtures for any excess resources you might have.
The ministers will only initiate and respond to trades involving material goods such as oil, metal, energy, rare
materials and supplies, and they will not trade cash, blueprints, equipment or territories. You will continue to
conduct those deals yourself, and you may also initiate your own trade goods deals over and above the ones
arranged by your ministers. This is discussed in more detail in the Diplomacy section.

cludes a summary of all active trade agreements

Convoys

Convoys are the essential vessels used to ferry natural resources from
any provinces that you control overseas back to your national stock­piles, and to send supplies and fuel to your troops abroad. Without
convoys, you will be unable to import resources from your own colo­nial possessions, if any, or to keep your supply chains open and opera­tional. HoI2’s convoy system is somewhat abstracted, relieving you of
the need to micromanage their specific actions. Rather than giving or­ders to individual ships, you will designate a route and then make spe­cial convoy and escort vessels available to traffic along and defend that

HEARTS OF IRON DOOMSDAY

route. The convoys will then go about their business and only appear as routes on the map when viewing it
using the convoy mapmode. Their assigned route is subject to enemy interference, though, with convoy ves­sels being common prey for enemy submarine packs. Escorts will attempt to fight back, defending the other­wise unarmed supply vessels, but you would be well advised to manufacture new convoy and escort vessels
on a regular basis if your economy depends heavily on imports or if your troops will be engaged in many
overseas campaigns. In any case, convoys will attempt to transport their goods using the safest route possible
between the origin and the destination and will adjust these routes periodically in response to enemy activi­ties.

The convoy section of the Production Folder allows you to quickly review your existing convoy routes. For
each one you will see the port of origin, port of destination, cargo type, and the number of convoy vessels and
escorts currently assigned to the route, shown as convoys/escorts. If this text is red, the number of transports
assigned to the route is too few to maintain it at full efficiency. If the text is white, you have a sufficient number.
Immediately below the text will be the icons of the types of resources that this convoy has been permitted
to carry (see below). This does not necessarily mean that they are being shipped, however, since the depot
may not have any of that type of resource. The actual daily transport of goods is displayed in a tooltip that
appears when you hover your mouse over the route. Limited air supply of ground forces is possible, but this
is not treated as a regular convoy so it won’t appear in this summary. See the Air Combat section for details
on air supply.

At the top of the summary area, you will see the number of transports and escorts in your convoy pool that
are currently without an assignment and are available for new routes or for the expansion of existing routes.
Click on the Convoys button to display the Convoy Management interface where you can adjust many com­mon aspects of your convoy routes. You may view and control even more details of individual convoys’ activi­ties using the Convoy Details interface, accessed by clicking on the route’s listing in either the main Production
Folder’s summary or in the Convoy Management interface.

The Convoy Management and Convoy Details Interfaces

The upper portion of the Convoy Management interface is similar to the
production folder’s basic view, providing a scrollable list of all existing con­voys and an expanding tooltip that details the goods being transported.
For each route, you will see the number of convoys and escorts currently
assigned to that route, which will be red if you have not assigned enough
vessels to the task. There are also small “+” and “-” buttons beside these
that allow you to change the quantities. Holding down the “Shift” key as
you do so will increase or decrease the numbers in larger steps. Each route
also has a prioritise button (an arrow pointing upwards) that is used to
assign the relative priorities of each route if you elect to have the route
maintained automatically for you. This indicates which routes are most
important to you, ensuring that any available convoy vessels will be as­signed to keep those goods flowing if you have an insufficient number of
vessels to maintain all of your routes at full capacity. We’ll discuss how to
use convoy automation in a moment.

You can click on a route listing either here, or in the Production folder’s

Convoy Details interface includes information about the route that the convoy is taking and allows you to set
limits on the types of materials that the convoys will carry. You cannot adjust the convoy’s route, but you can

summary to display an even more detailed interface for that convoy. The

0

specify exactly which materials are to be transported by checking or un-checking the appropriate resource
checkbox. You may also adjust the number of vessels assigned to the route, and you may cancel a route
altogether by clicking the Cancel Convoy button in the middle of the panel.

The lower section of the Convoy Details interface is the same as the Con­voy Management’s lower section and is used to create a new convoy route
and to control the level of route automation. To manually create a new
convoy route, click on the button that corresponds to the type of route you
wish to establish: a resource or a supply convoy. You will then be asked to
select a port of origin from the list of possible valid ports. This is which­ever port you want the convoy to use as its starting point. You are then
asked to select from a list of possible destination ports for your resources.
Click OK to establish the route. By default, a supply convoy will pick up
supplies and fuel if they are available and will deliver them to the destina­tion port. A resource convoy will pick up all natural resources and deliver
them to the destination port. Goods carried by a convoy to a destination
port that is directly land-linked to your capital will automatically transport
those goods to your capital and add them to your national stockpile. If this
is not possible, a new depot will be created in the destination port’s prov­ince and all inbound goods will be placed there for subsequent distribu-

from one depot to another. This is a very useful technique, particularly when supplying forces in the Pacific
theatre, since it may require fewer vessels and is somewhat less susceptible to enemy anti-convoy activities
than creating a large number of long-distance direct routes.

After you have created the convoy route, you may need to use the Convoy Details interface to make adjust­ments to the default goods being transported and to allocate convoys and escorts to protect them before it
will become active. You won’t need to do this if you have a sufficient number of unassigned vessels and have
enabled the “auto-maintain convoy” option, but you might want to adjust its priority. Once created, it will
usually require a few days of game time before you begin to see much activity along a new route since the
flow of materials will take some time to be established. You should also check the route periodically if you are
maintaining it manually to ensure that it is still active. It might cease to be functional if there are no materials
available for it to carry, or if enemy anti-convoy activities are intercepting and destroying the majority of the
vessels.

The most common error that new players make when manually establishing convoys is to forget that oil is
both a resource and a supply. If you set up a default supply convoy to a depot and a default resource convoy
to pick up from that depot and transport raw materials elsewhere, the oil that you intend to place in that depot
as fuel for your troops will be carried away by your second convoy since it’s a resource. After you’ve done this
a couple times and suffered the devastating battle consequences of being out of fuel, you’ll probably begin to
remember to set the material transport limitations.

When you are at war, you should also be sure to check the status of your convoys on a regular basis. Enemy
vessels and aircraft can be ordered to engage in convoy disruption activities that will attempt to locate and sink
a portion of your merchant marine. While escorts will help mitigate this to a degree and convoys will adjust
their routes to minimise losses, it is still probable that you will lose some percentage of your shipments and
that some of your transports and escorts will be sunk. You should make provisions to build new convoy vessels
periodically to replace these inevitable losses.

tion. Note that you can create a second convoy route to transport goods

HEARTS OF IRON DOOMSDAY

Automating Convoy Management

If all of this sounds just a little bit too complex and overwhelming, you’ll be very happy to know that you can
delegate almost all aspects of convoy management using the three buttons that appear at the bottom of both
the Convoy Management and Convoy Details interfaces. You may elect to have your “unseen assistants” estab­lish and remove resource convoys automatically for you as required. You may also have them do the same for
your supply convoys, and you may ask them to maintain the routes by assigning new transports and escorts
as they become available. If you automate convoy management you will still be responsible for ensuring that
there are a sufficient number of convoy and escort vessels for the “assistants” to work with, and for assigning
priorities to each of the routes.

Resource Depots

The lower right portion of the Production Folder is a scrollable listing of all the resource depots that you cur­rently have throughout the world. Depots will exist for one of three reasons: either it is your nation’s capital;
you have natural resources being extracted from provinces in that region but there is no direct land link to
your capital, so they are being stockpiled locally to await convoy transport to your capital; or a depot has been
established to act as a supply dump of oil and supplies for your troops in that region. I mentioned above that
you can use air transports to supply your armed forces, although this is very costly and inefficient so it should
only be done in case of emergency. This is an air mission (described in detail in the Air Combat section) and
does not appear in the convoy listing, but the depot of supplies and oil that you establish by doing this will
appear in the depot listing.

The first depot in the list will always be your national capital and will reflect the same resource stockpiles that
are reported in the Top Bar and National Resources summary. All natural resources listed as being located at
one of your other depots are not included in the National and Top Bar values and will not be available to your
factories for use until they are shipped via convoy to your capital. Generally, you will wish to move all natural
resources from your depots to your capital as soon as possible to avoid risking their capture and to make them
available to industry or international trade. In the case of a depot that is also supplying your armed forces, you
will probably want to leave some oil behind and ship some supplies to it.

The Diplomacy Folder

General Overview

While the Main Map interface screen may be your
window on the world, the Diplomacy Folder screen
is the interface that governs most of your interac­tions with it, or at least those that don’t directly in­volve bloodshed or subversion. It is here that you
will form alliances, declare wars, negotiate trade
agreements, flex your international muscles or lend
a helping hand to a friend (or would-be friend), and
generally conduct all of your diplomatic activities.
This is also the folder where you may review the

the world and, perhaps even more significantly, control your own. Let’s look at the main areas of the folder
before we go into the detailed descriptions of the information and controls available for each:

2

domestic policies and governments of the nations of



HEARTS OF IRON DOOMSDAY

1 Your Nation and Government: The top left corner of the folder will always display your nation’s flag and

name, as well as your form of government and current belligerence value. If you click on the flag, details
of your nation will be displayed in the rest of the interface.

2 World Nations: This is a scrollable list of all nations in the world. If a nation ceases to exist, it will be

removed from this list and any new nations that are formed during the game will be added to it. The
information displayed in the rest of the diplomacy folder will change depending on which nation you
have selected, as will the options available to you in the interfaces. Beside each nation’s name, you may
see one or more resource icons. This indicates that the nation currently has a daily surplus of this item and
might be interested in trading it for something else. This display is updated at midnight each day and the
icons will not be displayed until 24 hours have elapsed from the start of the game. Hovering your mouse
over a national flag will display a drop-down tooltip that includes some basic information about that
nation’s government, your relationship with them, its belligerence, as well as its available and base IC.

There are tabs at the top of this area that you can click to filter the list and display only those nations
that are members of one of the three major factions (the Axis, Allies or Comintern) or a particular part
of the world (Africa, Asia, the Americas, or Europe). Many nations will not be aligned with one of the
three major factions, especially when it’s early in the game, so you will need to locate them in the master
listing, which can be returned to by clicking the All tab. Another very quick and simple means of selecting
a nation is to click on any province on the main map that is currently controlled by that nation. Their flag
will be displayed in the information panel and clicking it will automatically bring you to the Diplomacy
Folder and pre-select that nation.

3 Selected Nation, Government Type, Relationship and Diplomatic Details: The top of this area will

display the flag and name of the country you have selected from the list; by default, it will be your nation.
Beneath the flag, you will see that nation’s form of government, your relationship with them, unless
the selected nation is yours, and that nation’s current belligerence value. All of the known details of its
diplomatic status and activities will be itemised in a scrollable list below this, including any wars that it is
engaged in, alliances it has, as well as a variety of other possible diplomatic conditions that might exist.

4 Selected Nation’s Government and Cabinet: Here you will see photographs of the selected nation’s

head of state, head of government and cabinet. If you have selected your own nation, you will see the
people that currently occupy these positions in your government and cabinet and you’ll be able click
on a portrait to change the minister if a replacement is available. Expanding tooltips will appear over
each picture, detailing that person’s traits and any bonuses or penalties these might give. Note that in
some cases, an individual may hold more than one position. In particular, the head of state and head of
government are often the same person if the type of government does not distinguish between these
positions.

5 Diplomatic Options: This area is the main diplomatic interface of the folder, allowing you to access

a variety of possible options. The actions available to you will depend on the nation selected, your
respective governments, your relationship, and any belligerence values.

6 Selected Nation’s Domestic Policies: This area displays the domestic policies of the nation you have

selected from the list. If you have selected your own nation, this will also be the interface you use to
make changes to those policies. This may rarely be done, and only within certain restrictions that are
determined by your type of government.

HEARTS OF IRON DOOMSDAY

Domestic Policy

Overview

Our detailed look at the Diplomacy Folder begins with the Domestic Policy area, displayed as seven distinct
policy sliders. Don’t be fooled by the small size of this part of the screen; it’s a deceptively important one!
Each slider has a label at either end, representing two opposing views. The slider position determines which
view the nation tends to favour, and how strongly it does so. We’ll take a closer look at the meaning of each
in a moment.

Domestic policies have far-reaching implications on a nation. Some will give bonuses or penalties in your
day-to-day activities, while others will limit or affect your diplomatic or domestic actions, or will alter the nature
and quality of your armed forces. The first two sliders determine the type of government that is in power and
will have a limiting effect on the allowable positions of some of the other sliders. Further, they determine which
ministers will serve on the cabinet and can have a significant impact on your relationship with other nations.
While you can examine any nation’s domestic policies, it is your own country’s policies that will be of greatest
interest to you. You can easily review these by clicking on your nation’s flag in the top left corner of the folder.
Hovering your mouse over any slider will give you details about the current effects that your policy setting has
on your nation, and hovering it over the small “+” or “-” buttons at either end will show the effects of changing
your policy by one step in that direction. Wait! Don’t change them quite yet…

The domestic policy of your nation can be changed by clicking on either the “+” or “-” button on the end of
a slider. Drastic policy changes are impossible and certain types of governments will place restrictions on the
allowable positions of some of the sliders. You are allowed to make only one policy change every six months,
and this is limited to adjusting only one slider by only one step. Since each slider has ten distinct steps and
it may take several of these to achieve any significant change, you should carefully consider your policies
and determine what change will benefit you most before making a change. The only other means of altering
domestic policy is through the choices you make when you receive one of the game’s special events, or as a
result of several other important game actions.

The Democratic - Authoritarian Slider

This slider represents a nation’s political pluralism - whether it is highly democratic, highly authoritarian, or
somewhere in between. When combined with the setting of your Political Left-Political Right slider, this will
determine your government type and the default ministers who will rule the nation. Your level of democracy
will have a large impact on your ability to declare war on a nation. The more democratic you are, the more
provocative or belligerent another nation must be before your public will allow you to declare war on the
offender.

The populations of democratic societies generally expect higher levels of consumer goods and are more
upset when their government plunges them into war; however, provinces that are occupied by a democratic
nation are somewhat less prone to dissent as they are given more freedom of expression.

The Political Left - Political Right Slider

This slider determines the general political leanings of your nation. When combined with the setting of the
Democratic-Authoritarian slider, this will determine your government type and the ministers who will rule the
nation. It can also have a significant impact on your relationship with other countries and may limit the allow­able settings of several of your other domestic policy sliders (see Government Types below).

The Open Society - Closed Society Slider

This slider determines the measure of freedom enjoyed by your citizens. An open society is somewhat more





HEARTS OF IRON DOOMSDAY

prone to national dissent and generally has a more difficult time countering enemy intelligence activities,
although any conquered provinces will have a lower level of partisanship. A closed society is better able
to repress partisans and counter enemy intelligence activities, but is more likely to have trouble controlling
national dissent. Scientists who work on projects for open societies also tend to require somewhat higher
levels of funding.

The Free Market - Central Planning Slider

This slider affects aspects of your economy. Free market societies enjoy reductions in the cost and time re­quired to complete production orders and upgrades, not to mention that they generate more cash from their
IC allocation to consumer goods, though demand will be higher, too. Scientists will also earn considerably
higher salaries when working on research projects. A more regulated, centrally governed economy will offer
lower salaries to their scientists but the cost and time required to complete production orders and upgrades
will be greater. While consumer demand will be lower, correspondingly less cash is generated from IC alloca­tions to consumer goods.

The Standing Army - Drafted Army Slider

This slider determines whether a country maintains a largely professional military force or whether service­men are only drafted in times of trouble. Nations who rely on drafted armies will receive a significant gearing
bonus, but the organisation of their armies will be lower and they will gain experience more slowly. They are
also more costly to upgrade to new technologies. Nations with standing armies tend to be better organised
and even their raw recruits will be more experienced and have a lower cost when being outfitted with new
technologies. However, they will not receive nearly as large a gearing bonus in the industrial sector.

The Hawk Lobby - Dove Lobby Slider

This slider indicates the relative strength of the pro-war versus the pro-peace lobby in a nation. Nations with
a strong hawk lobby will enjoy reduced production times and costs, while more peaceful nations will enjoy a
better return on all IC allocations to consumer goods and often enjoy a somewhat more accepted international
diplomatic position. You will find that a public that favours a more hawkish political stance volunteers more
readily for military service and won’t have as much dissent when their government under-funds its consumer
goods allocation.

The Interventionism - Isolationism Slider

This slider determines a nation’s interest in being part of and interfering in the larger international community.
Nations that actively involve themselves on the world stage enjoy fewer restrictions and lower costs for con­ducting diplomatic activities but are generally poorer at smoothing over any diplomatic blunders. They are very
likely to create or join alliances. Isolationist nations incur higher costs when they engage in diplomatic activities,
and in some cases, they may not be able to engage in them at all. A strongly isolationist nation will refuse to
join an alliance and cannot even be invited, cannot create an alliance, and cannot guarantee another nation’s
independence, though such nations are generally good at maintaining and repairing poor relationships. The
position of this slider will also partially determine the necessary level of belligerence that another nation must
have before you will be allowed to declare war on them. The more of an interventionist you are, the less provo­cation will be required before you may interpose and the less upset your public will be when you act on it.

Government

The position of the first two domestic policy sliders will determine the type of government that is in power
in a nation, as well as the ministers who are available to help rule it. Each government type imposes certain

This government enjoys modest international relationships with slightly
less central planning. This permits further policy flexibility for trade and the
openness of its society.

This nation is somewhat more heavily weighted towards central planning
and has some difficulties on the international scene. However, it does allow a
greater openness of society and better trade flexibility.

This government is generally poorly regarded by the international community
and tends to be more restrictive of trade and on the openness of its society.

Stalinist governments are not generally liked by other nations and are highly
committed to central planning, closed society and are very restrictive of trade.

This society is fairly flexible with regards to its internal markets, and may
be somewhat open or closed, depending on preference. Trade is somewhat
restricted, and although there is some flexibility in terms of how frequently it
intervenes in international affairs, this has little or no beneficial impact on its
relationship with other nations.

Neutrally regarded on the world scene, this government favours a free
market and is usually a very open society. Market liberals also tend to adopt
interventionist policies.

This very open society is usually far less inclined to meddle in foreign affairs
and is neither highly centrist in its planning nor highly supportive of a free
market.

Social democrats lean towards central planning and somewhat more
isolationist policies, occasionally harming their relationships with other na­tions. They do not attempt to restrict their societies, although they are never
entirely open either.

restrictions on the possible ranges of some of the other sliders. There are ten distinct forms of government
in Hearts of Iron II:

Cabinet and Ministers

These are the highest-ranking officials in a nation’s government. Unlike the various field officers who directly
command a country’s armed forces, the ministers are those who hold the highest levels of authority and carry
on their day-to-day business away from the front lines. Many ministers possess specific individual traits or
characteristics that may play a large role in certain aspects of your economy or military.

The cabinet of each nation is automatically assigned based on the prevailing domestic policy conditions,
particularly the type of government, and is formed of ten officials who will oversee its affairs. Each minister
may possess personality traits that make him ideally suited to hold that post, although in many cases there are
trade-offs between his natural expertise and his corresponding deficiencies. You can achieve amazing success





HEARTS OF IRON DOOMSDAY

simply by taking advantage of your ministers’ attributes and working to minimise or avoid the less desirable
aspects of their personalities.

Appointment of Ministers

Ministers are appointed automatically in Hearts of Iron 2 based on a nation’s domestic policies and drawn
from the available pool of potential officials in the region. Every country will appoint ten ministers to serve in
its cabinet, although in some regimes, a minister may occupy more than one cabinet position, most notably in
the case of a dictatorship, where the head of state will usually also hold the head of government post.

The ministerial files of the game not only include the names of almost every significant government official
of the era, they also contain additional “possible” ministers who did not historically occupy posts on cabinet.
During the course of play, these ministers may come to power as a result of the domestic policies you pursue,
or through civil war, dissident uprisings, an enemy-funded coup d’état, or as a result of special events. You
may also voluntarily change many of your ministers by clicking on the appropriate portrait and selecting from
the list of other available ministers. The ones that are listed will depend on your current domestic policies, so
you may find that some prospective ministers may not be available until you have made a significant change
to your policies.

It is not practical in the space available in this manual to detail each of the various ministers’ possible traits and
their effects. This information is clearly displayed in the expanding tooltips that appear when you hover your
mouse over each person’s portrait. The following is a general summary of each nation’s cabinet positions:

The Head of State

The Head of State occupies the highest position in the nation. He will often have a trait that will have a sig­nificant effect on your nation and the assigned AI character’s actions. The person that occupies this position is
usually - though not always - determined by the type of government that is in place.

The Head of Government

The Head of Government is in charge of directing the nation’s general affairs and its cabinet. He may have
any one of a number of widely varying traits that may affect the industry, diplomacy or military success of
his nation.

The Foreign Minister

The Foreign Minister is charged with conducting the majority of a nation’s international diplomacy and may
possess traits that will benefit or hinder those activities to various degrees. These traits will often give bonuses
to certain diplomatic options while incurring penalties for other types of negotiations.

The Minister of Armament

The Minister of Armament oversees all research and production in a nation. His traits will usually affect
research times, production time and costs, and resource availability, although most characteristics will involve
potential trade-offs in opposing areas.

The Minister of Security

Charged with maintaining the internal stability of a nation, the Minister of Security will usually possess traits
that will affect domestic affairs. He may be proficient at maintaining lower levels of dissent, or partisanship, or
be adept at preventing hostile intelligence activities.

The Head of Military Intelligence

The Head of Military Intelligence is the counterpart to the Minister of Security. He will direct your intelligence
efforts abroad and his agents could provide vital and timely information about your enemy’s activities or carry

HEARTS OF IRON DOOMSDAY

out clandestine operations to weaken an enemy’s position. Depending on his specific area of focus, this could
result in advanced warning of large troop build-ups, the theft of enemy technological secrets, important infor­mation about the enemy’s industrial activities, or may affect the likelihood of certain spy missions.

The Chief of Staff

The Chief of Staff is responsible for a nation’s combined armed forces and will usually subscribe to a “school”
of thought about how best to wage war. He is usually biased towards one of the three main divisions of the
armed forces (army, navy or air force) and will give that one particular group an extra edge over the others.

The Chief of the Army

The Chief of the Army directs the overall activities of a nation’s ground forces. He will usually have a combat
doctrine that provides bonuses to certain types of engagements or to a specific type of land unit that he prefers
above the others.

The Chief of the Navy

The Chief of the Navy directs the overall activities of a nation’s maritime forces. He, too, will tend to prefer a
specific doctrine that may have decisive benefits and may favour one type of vessel over all others.

The Chief of the Air Force

Like his army and navy counterparts, the Chief of the Air Force will subscribe to a doctrine that may give some
of your aerial units advantages in certain types of missions.

Other Nations’ Domestic Policies and Ministers

There is a tendency among newer players to pay very little attention to the policies and cabinets of other
countries. While it is arguably not particularly vital to review the domestic situation of smaller, more remote
nations with whom you will rarely come into contact, it can be a serious oversight to ignore the capabilities of
an enemy. You should evaluate a foe’s strengths and weaknesses, seeking to take advantage where you can
and perhaps even to tailor your own domestic affairs to either counter or exploit them.

Dissent and Partisans

Dissent is a global effect in your nation and can be thought of as a barometer of overall public satisfaction.
It affects all provinces equally, be they national, owned or occupied, and it is displayed in the Top Bar at all
times. There are two direct and important effects of allowing your nation’s dissent levels to rise: you will suffer
decreased performance from your armed forces, and you will increase the likelihood of civil disobedience.

As far as your public is concerned, the most unsettling action you can take is to plunge your nation into war
without cause or provocation. In some cases, your type of government and your domestic policies will prevent
you from going to war at all, but in those instances where you are permitted to make a declaration and choose
to do so, some portion of your public will object to this action, causing a sudden rise in dissent. The amount of
this increase will depend entirely on your “reasons” for going to war and are also modified by your domestic
policies. If you are declaring war simply to satisfy your territorial ambitions or for the sheer fun of waging war,
your public will take a very dim view of it. If you declare war as a result of a casus belli - a “just cause” - then
your public will be far more understanding. A casus belli may result from another nation having control of one
of your national provinces as displayed on the diplomacy mapmode. If you guarantee the independence of a
nation and then declare war on a third party that attacks it, your public will be quite supportive and you will
receive no increase in dissent. Dissent will also fail to rise if you find yourself at war as a result of one of your
allies declaring war, or due to a nation declaring war on you or a member of an alliance to which you belong.
Increases in dissent can also occur when you cancel a non-aggression treaty with another nation, when you





HEARTS OF IRON DOOMSDAY

liberate a state that is a puppet, or if one of your national provinces is the subject of a nuclear attack.

Dissent is not limited to foreign affairs. The most common reason for its increase is actually as a result of your
domestic failure to meet the consumer goods expectations of your public or the supply needs of your military.
If you allocate too little of your industrial capacity to consumer goods production, then dissent will begin to rise.
The demand for those goods and the rate at which dissent rises if you fail to meet that demand will depend
on your domestic policies and possibly on your cabinet ministers. Failing to provide adequate supplies for the
army, navy, and air force will also cause your public to resent this inattention to your armed forces.

As the level of dissent rises, the most immediate effect you will notice is that the performance of your armed
forces will begin to suffer. Low levels of dissent will only have a marginal impact on their combat abilities,
although higher levels may place your forces at a significant disadvantage. There is also a chance that dissent
may reach a level where your public will rise in open rebellion and seek to overthrow what they view as a
corrupt and malevolent government. They will also be far more open to accepting foreign financing of a coup
d’état, something that could have devastating consequences for your nation.

The only way to reduce public dissent is to allocate excess IC to the production of consumer goods, which
also has the side benefit of generating additional cash for your national treasury. The rate of the decrease is
determined by the extent of your over-allocation and by your domestic policies, and may be further modified
by the capabilities of your cabinet ministers. If you have suffered an increase in dissent as a result of an en­emy’s nuclear attack, you can immediately eliminate this by launching a retaliatory nuclear strike of your own,
perhaps because your population is now so utterly terrified about this escalation that they aren’t vocal about it
any longer. Note that initiating a nuclear war will not eliminate dissent caused by other actions.

Partisanship is a concern only in non-national provinces and is tracked on a province-by-province basis. Non­national owned provinces will usually have fairly low levels of militancy, while occupied provinces will generally
be much higher. In both cases, this may also be compounded by your current level of national dissent. Detailed
partisanship values are displayed in the information panel when you are reviewing a province’s details, or may
be seen as a graphic representation on the main map when you click the partisan mapmode button.

Partisanship damages the economy of a province, hampering the supply and movement of troops in that
territory, and increasing the likelihood of open rebellion. In owned provinces, this effect is slightly less than
in occupied provinces, but neither should be expected to contribute a very high percentage of their industrial
or resource potential. The risk of rebellion is represented directly by the partisanship level and will be further
modified by your national dissent values, and this same partisan percentage is also applied as a reduction to
your nation’s transport capacity. This may be overcome by maintaining a large enough standing force to sup­press their efforts; however, neither type of province will contribute to your national manpower pool except
under very unusual circumstances, and each occupied province you control will reduce your transport capacity
by at least 1 point.

The only way to reduce the level of partisanship in a province is to keep the resistance movements in check by
placing troops there to maintain order. Most land units have a suppression value. This value is subtracted from
the partisanship value when the troops are located in a province, and the value is doubled when the troops
have been specifically ordered to engage in anti-partisan activities, though we’ll look at how to do this when we
get to the Land Combat section. If the suppression value is high enough, the additional percentage effects of
partisanship may be completely eliminated, but the base reduction to resource extraction and industrial capac­ity and the minimum loss of 1 point of transport capacity in occupied territories cannot be removed.

The factor that will most heavily influence partisanship and national dissent is the degree to which your
society is open or closed. Open societies have national province populations that will be considerably more
militant about your actions, but owned and occupied populations are generally very happy to be allowed to
express their opinions and are less likely to revolt. The opposite is true of a closed society. To a lesser degree

HEARTS OF IRON DOOMSDAY

your Minister of Security, who is responsible for such domestic affairs, may be able to influence the dissent or
partisanship levels if he possesses the correct skills.

Beware! Partisans and dissidents who rise in rebellion may be heavily armed and quite difficult to defeat. Fail­ing to deal with them promptly may result in them achieving independence, forming their own government,
and establishing a new nation that will be in conflict with your own. Neighbouring provinces may even decide
to join in the rebellion and it is quite possible that other members of the international community could be
drawn into the affair.

Diplomacy - International Affairs

Overview

We now turn our attention to international affairs - your nation’s ability to engage in diplomatic activities
with the world’s other nations. The options available to you when conducting diplomacy will depend on the
relationship that exists between your country and the nation with which you are attempting to enter into dis­cussions. The overall stance is of prime importance, whether you are allied, at war with, or neutral towards one
another. Other factors may also play a pivotal role in the likely success of your negotiations: your relationship
with the nation, your cabinet and most notably your foreign minister, your respective forms of government and
domestic policies, your prior diplomatic actions, your military successes or failures, and your overall wealth.

Other Nations’ Domestic Policies and Cabinets

While you have no direct way to affect other nations’ domestic situation, you should periodically review the
domestic policies and cabinets of the other nations in the world, particularly those with whom you are at war.
This may give you an added insight into their overall strengths and weaknesses and might suggest tactics that
are more likely to be successful. This is easily done by selecting a nation’s name or flag from the list of world
nations in the Diplomacy Folder. You can also click on a nation’s flag when viewing one of its Province Details
to go directly to the Diplomacy Folder with that nation pre-selected for you.

National Relationships

Hearts of Iron II uses a diplomatic model that assumes that each nation in the world has a specific view
about every other nation in the world, and that any two nations are capable of conducting at least some level
of diplomacy. The success or failure of a diplomatic action, as well as the diplomatic options that may be avail­able, will depend on the relationship value that exists between the two nations. When you select a country in
the Diplomacy Folder, you will see your current relationship value with that nation displayed near the top of
the screen. This value indicates generally how that nation “feels” about you and can range between -200 (you
detest one another) and +200 (you’re the best of friends). Although you cannot view a nation’s relationship
values with other nations in the world, these are tracked and will modify the diplomatic activities between AI­controlled nations. If you examine the details of the diplomatic agreements that they have in place, you will get
a pretty good idea of their general leanings. Nations with similar government types will tend to be very friendly
towards one another, as will nations who are joint members of an alliance.

Your relationship with a country will affect the diplomatic options available to you and will also impact on the
likelihood of a proposal being accepted. Alliances are usually limited to nations that have a very good relation­ship, at least at the time that the alliance is first formed, and trade deals and negotiated deals are far more
likely to be met with a favourable response if your nations are on friendly terms. Some diplomatic options are
specifically designed to improve relationships between nations, while others are almost guaranteed to result in
a worsening of this value. In most cases, a relationship will improve when a diplomatic proposal is accepted,
thus opening the door to further interactions, and will worsen if it is declined. The other factor that affects

0

1

HEARTS OF IRON DOOMSDAY

international relationships is each nation’s belligerence.

Belligerence

Every nation has a belligerence value that is displayed below the relationship value. Think of this as a special
means used to measure and evaluate each nation’s actions. The more actively aggressive you are, the higher
this value will become. Entering into wars without provocation, annexing countries, being caught red-handed
when attempting espionage, and similar activities will tend to make other nations think of you as belligerent
and a danger to their continued survival. Freeing nations from oppression or even just keeping a low profile
over a significant period of time will tend to make nations think of you as being more friendly and trustworthy.
Each of these actions or inactions will alter your belligerence value and affect your diplomacy.

The most visible result of a high belligerence value is to exert a continuous downward pressure on your
relationship values with other nations. Even your closest allies will begin to view you with some degree of
suspicion, overcoming the normal bonuses that apply to that relationship. Neutral countries will tend to dislike
you rather intensely, and enemies will become committed to your destruction. If you allow your belligerence
to reach epic levels, you could even find that the entire world suddenly becomes obsessed with your destruc­tion.

A less obvious effect is that a limit is placed on democracies where they may not declare war unless the
“target” nation has a sufficiently high belligerence value and the democracy has a strong enough policy of
intervention. These factors are weighted, meaning that the more democratic a nation is and the less it leans
towards interventionism, the higher the required belligerence value of a target nation needs to be in order for
the democracy to declare war.

Other than going out of your way to free nations that you have already conquered, you can reduce your own
belligerence value by being on your best behaviour for a prolonged period of time. If you do this for long
enough, the international community will slowly forgive and forget your previous transgressions and your
belligerence value will slowly decrease.

The Three Factions - The Allies, The Axis and The Comintern

While an alliance can be formed between any two neutral nations, there are three pre-existing factions
in Hearts of Iron II that are considered to be natural and dominant alliances: the Axis, the Allies, and the
Comintern. A nation may only belong to one alliance and, upon joining, is automatically considered to be
allied with any other nation which is also a member of that alliance. A nation that is part of a “minor” alliance
(not the Allies, Axis or Comintern) may voluntarily leave that alliance and join one of the major factions, but it
may not join another minor alliance.

• The Allies: This alliance is headed by the United Kingdom and will appeal primarily to democratic nations.

In virtually all games, there are a number of nations that are already a member of this alliance, mostly
Commonwealth nations, and possibly France or the USA, depending on the game. In several of the battle
scenarios, the Allies may actually be treated as a single nation rather than as a collection of nations, using
a special flag with a green star on it as its insignia. In the Doomsday campaign, the Allies will begin the
game at war with the Comintern.

• The Axis: Germany begins the 1936 Grand Campaign game as the only member of this alliance of fascist

nations, though others may be interested in joining. For game purposes, Japan is also treated as a fascist
nation to increase the probability that they will join the Axis alliance at the outbreak of war. In the Dooms­day campaign, the Axis has been defeated and no longer exists.

• The Comintern: The Soviet Union leads the alliance of communist nations, and in most games Mongolia

and Tannu Tuva will also begin as members. Although historically the Comintern and Allies formed what
would normally be viewed as an alliance, this relationship is not established in the game setup of later

HEARTS OF IRON DOOMSDAY

campaigns to allow the player a little more freedom of diplomatic action, although both the Comintern
and the Allies will often both be at war with Germany. In the Doomsday campaign, the Comintern begins
the game at war with the Allies.

I should point out that the nations who lead these three factions are not only considered to be alliance leaders
(see below) but are also programmed to be extremely reluctant to agree to any peace terms other than the
outright annexation of a member of another alliance. You should expect any other offers of surrender to be
rebuffed when they are involved.

There is a hard-coded end to the game in 1953. Due to popular demand from players, this “cap” is removed
if two of the three major factions have been completely eliminated from the game prior to December 30th of

Spheres of Influence

Before we look at the various diplomatic options, you should be aware that there is an additional component
to diplomacy that is not readily apparent from any of the interfaces but will have an impact on the outcome
of your actions. This is termed “spheres of influence” and represents the historical situation where a number
of larger nations took a very dim view of other nations conducting diplomacy in an area that was geographi­cally close to their interests without their expressed permission. This is most easily seen by watching which
countries have their independence guaranteed by larger AI nations, since they will typically do so for any
nation in their sphere that isn’t diametrically opposed to their form of government. Be warned that stepping
on their diplomatic toes can result in no small degree of resentment, a drop in your relationship values, and
possibly even war.

Initiating Diplomacy

To initiate any diplomatic action, select the country from the listing at the left side of the Diplomatic Screen.
The Diplomacy Options area will now display a list of all available actions that you may take with this nation.
Ones that you may perform immediately are highlighted in orange, while others may be greyed out if you fail
to meet a necessary condition to initiate that action, generally a case where the relationship or belligerence
values are too high or too low. Some diplomatic options require cash to perform, so this could also prevent
you from taking an action until your national cash reserves have increased. There are also some diplomatic
options that will only appear if you are at war with a nation, or if you are on peaceful terms. There are also
options that will only be displayed if you have selected your own nation as the “target”. A tooltip will appear
when you hover over an option, briefly detailing what it means and also informing you of the cost of the action
and any prerequisites that you currently fail to meet.

Once you decide on an action, click on it. In many cases, a new interface will appear that allows you to specify
additional details, while in other cases the action may take place immediately or you may be asked to confirm
the action. If there is a cash cost for the diplomatic action, it will only be deducted when you confirm the action
and dispatch your diplomat. You will not lose the money if you change your mind and cancel the action, but
once confirmed, the money will be deducted whether or not the diplomatic offer you send is agreed to. For
instance, the cost of sending a diplomat to negotiate military access will not be returned to you if the access is
declined. The cost of a diplomatic action will fluctuate, depending on your domestic policies, your cabinet, and
the size of the nations involved, which explains why I don’t give precise costs in the sections that follow. The
tooltips will indicate the exact cost of each action.

Once you have sent a diplomatic message to a nation, you will have to wait for a period of time before you are
able to initiate any further diplomacy with that nation, although you may conduct diplomacy with other nations
if you wish. If a response is required, you will usually receive it within a day or two, although human players
may take longer to answer in multiplayer games, but you must wait a full week before another message may

2



HEARTS OF IRON DOOMSDAY

be sent to that nation. When you receive a diplomatic message that requires a response, usually a trade offer,
you will have a limited period of time to respond before it becomes invalid and disappears from your screen.
The following are the various diplomatic options that may be available to you:

Offer Trade Agreement

There are two different types of trades that can be arranged between two nations: a trade agreement and a

trade negotiation. Trade negotiations are one-time transactions that may involve a very wide range of items,

while trade agreements are open-ended deals that involve an ongoing daily exchange of resources. There is
a small cost required to propose a trade agreement. When you click on the offer trade agreement option, a
secondary interface appears.

Each of the resources, including supplies and cash,
will be represented by a slider on the interface.
There will be maximum end points set for each
slider, limiting what you may request or offer. These
endpoints are based on the daily rate of change of
each of the resources displayed on the right side for
your nation and on the left side for the nation with
which you are negotiating. If you have no daily in­crease of a resource, then you will not be able to
offer that item regardless of your stockpiles, and if
the target nation has no daily increase of an item,

this is that you may offer more than your own daily rate of change of money or supplies if you currently have
stockpiles of those items, but you cannot request them regardless of that nation’s stockpiles. You can check the
resources that a nation might be interested in bartering before you open the interface by looking at the small
resource icons adjacent to the country’s name in the diplomatic list. An icon will indicate a daily surplus of a
resource and means that you might be able to barter for it (reminder: these icons are updated at midnight
each day and will not appear until the first game day has elapsed).

To set the terms of the proposed trade agreement, simply adjust the sliders to indicate the resources you
would like to exchange. You can do this by dragging the bar with your mouse, or by using the “+” and “-” but­tons at either end of the slider. Clicking on a button while holding down the “Shift” or “Ctrl” keys will adjust the
values in greater increments; and right-clicking the slider will reset it to zero. Shifting a slider to the left of the
mid-point indicates that you are offering that resource, while shifting it to the right means that you are asking
for that resource in return. Once you are satisfied with the deal, click the OK button to send the offer. There
is a numeric display near the bottom of the interface that indicates the chance that the nation will accept your
proposal, but the accuracy of this value will depend somewhat on your minister of intelligence’s reports and
on your foreign minister’s persuasiveness. It is also affected by your belligerence value and by the relationship
between your two nations, and is further modified by both nations’ domestic policies. Don’t be too shocked
if a nation declines a trade in spite of a 100% acceptance probability, and it’s similarly possible that a nation
might agree to an offer even though the chance seems slim.

If a trade agreement is accepted, the exchange of goods will begin the next day and will continue until one
of the two nations decides to cancel the deal or is no longer able to supply that resource. However, there is
a trade efficiency factor that will modify the actual amounts that each nation receives. The efficiency reflects
the small losses in goods that may occur naturally if they must travel great distances, representing possible

you will not be able to request it. The exception to

HEARTS OF IRON DOOMSDAY

shipwrecks and such, and potentially very large losses if one or both of the nations involved is at war with an
enemy who is engaging in convoy disruption activities. The routes used by ships involved in trade agreements
are not shown on the supplies mapmode, but you must still be able to trace a line of supply through your
respective nations’ territories, or through the territories of those nations who are friendly towards you and with
whom you have a treaty of access. If you are unable to do that or if the route is heavily blockaded by enemy
vessels, none of the goods will arrive at their desired destinations and there is little point in proceeding with
the offer. Note that the full shipment of goods that you are sending will still be withdrawn daily, but you will
receive less in return.

Cancel Trade Agreement

If you have a trade agreement with another nation, you will have the option to cancel it if you wish. The most
likely reasons for doing so would be a drastic reduction in trade efficiency or a change in the availability of a
resource. When you click on this option, you will be given a list of all existing agreements that you have with
that nation. Simply select each of the agreements that you wish to cancel (an X will appear) and then click
okay. You may also cancel a trade agreement directly from the production screen by right-clicking on the trade
deal. There is no negotiation involved in cancelling an agreement, as it is cancelled automatically by this action.
However, it may damage your relationship with your former trading partner.

Open Negotiations

This diplomatic option is used to negotiate a one-time trade between your nation and any another nation
with whom you are not at war. The range of items that can be bartered may include resources, provinces
and even technological blueprints and equipment such as military forces. There is also a small cost involved
in negotiating the deal. An interface will appear when you click the open negotiations button that is divided
into two halves: the items being offered by your nation will be on the left and the items you wish to receive in
exchange will be on the right. As you assemble your offer, any provinces, blueprints, or equipment that would
be exchanged will be listed below the nations, and the amounts of any resources involved will be displayed
beside the appropriate icons towards the bottom of the interface.

Territory may be included in a deal with an ally by click­ing on the Provinces tab on the appropriate side and
then selecting the province name from the list. The
name of the province will appear at the bottom of the
screen when you click on it, and if you change your
mind you may simply click on that listing to remove it.
Note that you may only offer to buy or sell non-na­tional provinces, and the tab will be greyed out unless
you are allied.

The same techniques are used for including blueprints
or equipment in a trade. As with territorial exchanges,
this may only be done between allies, and you may
only request or offer blueprints for projects that a na­tion currently has the necessary prerequisites to begin

Resources may be offered or requested by clicking on the Resources tabs. You may only offer up to the total
amount that you have in your national stockpile, or request up to the amount that the other nation has in
its own, though again, this is an underhanded way to evaluate another nation’s resource stockpiles. As you

researching or is already researching.

HEARTS OF IRON DOOMSDAY

adjust the sliders, the amounts being offered or requested will be displayed beside the appropriate icon at the
bottom. Unlike the other three trade categories, resources may be traded between any two nations who are
not at war with one another.

As you assemble the proposal, the chance of the deal being accepted will be displayed at the bottom of the
interface. This is the base chance and is modified by the same sorts of factors as affect trade agreements, so
keep this in mind as you are putting the proposal together. The only deal that would be automatically accepted
is one where you are giving something away for free by offering something on your side of the interface while
requesting nothing in return. Once you are satisfied with your offer, click the OK button or click the cancel but­ton to abort the diplomatic action and the proposal will be sent. If the target nation accepts the deal, then the
exchange will be made. Beware! Negotiated deals are subject to the same trade efficiency modifiers as trade
agreements, so not all of the resources exchanged will necessarily reach their intended destinations; however,
provinces, equipment and blueprints are not subject to enemy embargo.

Influence Nation

This is a fairly common diplomatic action where you will send money to a nation in an attempt to improve
your relationship. There is no acceptance required for this “gift” and you will usually see at least some improve­ment in your nations’ relationship after choosing this option. The degree of change will depend on a variety of
factors, particularly the capabilities of your foreign minister and your relative government types, and will have
no additional or lasting benefits beyond this one-time boost.

Alliances - Offer Alliance/Bring to Alliance/Join Alliance

An alliance is a special relationship that exists between two or more nations, usually for protection and military
cooperation. New alliances may be formed between any two nations that are not already part of an alliance,
and whichever nation that creates the alliance will become the alliance leader. The alliance leader is the only
nation that may invite new nations to join the alliance, or accept the petition of an otherwise un-allied nation
who wishes to join. At the beginning of each campaign game, there are three pre-existing alliances: the Axis,
the Allies and the Comintern. Germany is always the alliance leader of the Axis, the United Kingdom is always
the leader of the Allies, and the Soviet Union is always the leader of the Comintern. There is a special case in
the 1936 Grand Campaign where Germany has no other allies at the beginning of the game; even if you are
the one to propose and arrange an alliance with Germany, Germany will be the alliance leader and you will
be deemed to have joined the Axis.

If you wish to form a new alliance, you cannot already be allied to any other nation and you must issue your
invitation to a nation that is also not already allied. If it is possible to create one, the offer alliance option
will be available in the list of diplomatic actions. Creating an alliance is usually a fairly expensive process and
is only likely to succeed if you have a good relationship with that nation and you have fairly similar types of
government. Larger nations will also tend to be somewhat disinclined to accept an offer made by a smaller,
weaker nation, and a nation that pursues isolationist policies is very unlikely to be interested in your offer. In
fact, unless a democratic nation with a strong isolationist policy is already at war, it cannot offer or be asked to
form an alliance, nor can it ask or be asked to join an existing alliance.

Once an alliance has been formed, the leader of the alliance may invite additional members to join, as long
as they are not already a member of another alliance, by selecting the nation and using the bring to alliance
diplomatic option. This will be a somewhat less expensive process than creating an alliance, and the likelihood
of the offer being accepted is governed by a similar set of considerations as forming alliances.

The exception to these rules is that the leader of the Allies, Axis or Comintern may invite another country who
is a member of a “minor” alliance to join the major faction. If the nation agrees, it leaves its existing alliance
even if it was formerly the alliance leader and becomes part of the major faction’s alliance.

HEARTS OF IRON DOOMSDAY

If you aren’t part of an alliance and wish to become a member of one, then you may petition the alliance
leader to allow you to join by selecting the join alliance option. This is a relatively inexpensive option and the
leader’s response is determined by the same set of preferences as has already been mentioned. If you aren’t
sure who the alliance leader is, you can select any member of the alliance and then hover your mouse over
the join alliance option. If the selected member isn’t the leader, you will see a tooltip that indicates that you
can’t ask this nation and identifies the alliance leader.

Alliances are very tight international bonds. Allies will share all of their territorial and armed forces information
with one another, removing the fog of war over those provinces for all member nations. They also share all
of the intelligence data gathered by their respective spies. If a member of an alliance declares war or is the
recipient of a declaration of war, then the entire alliance immediately becomes involved in the conflict. Alliance
members grant unconditional military access to one another. They will also provide supply for each others’
forces as required and will allow navies and squadrons to make free use of their bases.

Once an alliance is involved in a war, no member may leave that alliance until it has concluded a peace treaty
with the enemy and is no longer involved in the war. Be cautious when joining an alliance or adding new
members to it after it has been created. Only the alliance leader can ban a member nation from an alliance
and may only do so when the alliance is at peace. A particularly aggressive alliance can also be a threat to you
since all member nations are penalised equally with the belligerence cost of declaring war. An alliance leader
may decide to leave the alliance if he wishes (see below), at which point a new leader is chosen from among
the remaining alliance members. Similarly, if an alliance leader is annexed, a new leader will be appointed
from the survivors.

Alliance leaders always conduct peace treaties on behalf of the entire alliance, except for their own annexa­tion, and all terms agreed to by an alliance leader are binding on all other alliance members. Separate peace
treaties may be negotiated by non-alliance-leaders, but these are only binding on the two nations involved in
the negotiations. If an alliance leader negotiates a peace treaty with a non-alliance-leader, the terms agreed to
by the alliance leader are binding on his entire alliance, but the terms agreed to by the non-alliance-leader will
only affect his nation separately and the remaining members of that alliance will still remain at war.

Leave Alliance

If you are a member of an alliance, you may elect to disassociate yourself from it by selecting this option.
You may not leave an alliance if it is at war. The cash cost for leaving an alliance is quite steep and has a very
negative impact on your relationship with all other member countries. It goes without saying that you are not
allowed to declare war on another member of an alliance you belong to, and thus you must leave the alliance
if you wish to do so. Although it might seem odd and is admittedly very unlikely to happen, an alliance leader
is permitted to leave an alliance that he has created, as long as it is not at war.

Ban from Alliance

If you are the leader of an alliance, you may ban a member by selecting this option. You can only ban a
member if the alliance is not at war, and there may be political repercussions for doing so. At very least, your
relationship with that nation will be ruined and your actions might alarm the remaining members.

Send Expeditionary Force

This option allows you to lend a force to one of your allies. This is a free diplomatic option and relinquishes
control of one existing force to the target nation. The new national controller will then assume all responsibili­ties for issuing its orders and replenishing its losses, although it will remain under the command of the officer
you have assigned to it and cannot be disbanded. The nation you’ve lent it to may continue to use it until the
force is either eliminated or returned to you voluntarily, and you cannot request its return.





HEARTS OF IRON DOOMSDAY

When you select this option, an interface will appear that allows you to select which force to send to your
ally. Since the listing is a scrollable list of every force that you possess but doesn’t detail individual comple­ments other than total size, strength and organisation, I would recommend that you predetermine which one
you intend to send before initiating this action. If you currently control another nation’s expeditionary force
and wish to return it, click on this option in the Field Command Details menu to place it back under its home
nation’s direct control.

Assume Military Control/Relinquish Military Control

If you are allied to another nation, you may ask that nation to allow you to assume military control over its
forces. This request will cost a moderate amount of money to initiate and is likely to be accepted only if you
are significantly larger and stronger than the nation to whom you are making the request. If accepted, you
may then issue orders to that nation’s armed forces but their reinforcement and the decision as to whether to
begin production of any new units remains at their discretion. An AI nation will never agree to give you military
control of their forces if you have a lower base IC than it does.

Once you have been granted military control over a nation, you will remain in control until you return control
back to that nation via the relinquish military control diplomatic action, which has a modest cost associated
with it, or until the nation is annexed or leaves your alliance. If you grant military control to another nation,
the only way to regain control of your armed forces without being annexed and thus losing the game is to
leave the alliance.

Guarantee Independence

This is a relatively inexpensive option that allows you to guarantee the independence of a nation for the next
five years. This is a formal declaration that warns that you will take a very dim view of any hostilities that are
initiated against this nation and will very likely act in its defence. In the event that a third party declares war
on that nation, you will receive a +2 boost to your interventionism policy slider if that nation is on the same
continent as you are, and you will have a casus belli against the aggressor, allowing you to declare war without
paying a heavy domestic or international political price for that declaration. You are not required to make such
a declaration, though, nor do you suffer any ill effects for failing to do so. This is a method for a democratic
nation to bypass the normal belligerence and interventionism restrictions that would otherwise prevent it
from making a declaration of war. A highly isolationist nation is prohibited from guaranteeing another nation’s
independence.

Offer Non-Aggression Pact

This diplomatic option is used to arrange a two-year mutual non-aggression pact with another nation and
involves a moderate cost to negotiate. In essence, you are asking another nation to formally sign an agree­ment where both nations commit to remaining peaceful towards one another for the duration of the pact. If
accepted, it will usually have a positive effect on the relationship between your two nations and will incur very
hefty penalties if it is subsequently broken prior to its expiration. A nation cannot declare war on a nation with
which it has signed a non-aggression pact without first formally cancelling it, so this may offer you some degree
of security and, at very least, a minimum of a week’s advance notice before a war can occur between your two
nations. Once a pact has expired, there are no further assurances of peace, nor is there any additional penalty
if either nation subsequently declares war, beyond the penalty for the declaration of war itself.

Non-aggression pacts have a good chance of being accepted if you have a fairly competent foreign minister,
are significantly larger or more powerful than the other nation, have a fairly low belligerence factor, or enjoy a
decent relationship with the other nation.

HEARTS OF IRON DOOMSDAY

Cancel Non-Aggression Pact

This option will only be available if you have an existing non-aggression pact with a country. Although this
will severely damage your relationship, you are prohibited from making a declaration of war on a nation with
whom you have a non-aggression pact and thus you must cancel it before you will be able to declare war.
Needless to say, a country that breaks a non-aggression pact with you should be watched very closely. Further,
your population will be concerned at your flip-flopping policy so you will suffer an increase in domestic dis­sent.

Ask for Military Access/ Cancel Military Access/Revoke Military Access

This diplomatic option is a request to a nation to allow your forces to move freely through its provinces and
also to be able to trace supply through them. Without this, you are prohibited from entering or supplying
through a neutral nation’s territory. The cost to initiate this request is modest, but most nations will not be
willing to grant you access unless you enjoy a very good relationship. Allies automatically grant one another
access, so it is not necessary to arrange a special treaty unless you expect that, at some point, either you or
they might leave that alliance.

A military access treaty is not a reciprocal arrangement. A separate access treaty would have to be requested
by the other nation before it could move forces through your nation’s provinces. While an access agreement
is in place, you will be prohibited from declaring war on a nation that is granting you access. Beware! A nation
that grants you access is not under the same constraints and may declare war on you at any time and without
warning.

Military access may be revoked by either the nation at a modest cost by selecting the cancel or revoke military
access diplomatic option. If a nation does this, then it is likely that the nation is planning to declare war on
you in the near future, so you should be on your guard. Besides souring your relationship, a nation whose
access is revoked is also given a casus belli, allowing it to declare war without paying the usual domestic or
diplomatic cost.

I should point out that you are prohibited from attacking an enemy’s province using any land forces that are
located in a neutral nation’s territory, so it is pointless to arrange military access with a nation if your intent is
to try to exploit the enemy’s inability to attack you there.

Liberate Nation

This option is only available if you have selected your own nation and if you control provinces that can be­come part of a nation that does not currently exist. If you click liberate nation,n you will be asked what country
you wish to create from a list of possible nations. A tooltip will advise you of the provinces that will become part
of the new nation and cease to be considered yours. When you have selected the new nation and clicked OK,
the new independent nation will be formed and will be added to the list of nations in the world.

If you voluntarily liberate a nation, it will begin its new political life as a puppet regime and will send you a
portion of the resources it extracts from its provinces each day. It will also become a member of whatever
alliance you currently belong to, if any, and you will begin your new relationship with them at a very high
standing. The liberation of a nation will be greeted warmly by the international community, usually causing
your belligerence value to decrease.

Release Puppet

If you have a nation that is under your control as a puppet regime, you may decide to release it to its own
devices. The only immediate effect is that you will cease to receive any portion of its national income, but
this is considered a very benevolent action that is likely to improve your relationship with many parts of the
international community.

HEARTS OF IRON DOOMSDAY

Demand Territory

This option will be available if a nation owns one or more provinces that are considered to be your national
provinces, shown in dark green on the diplomatic mapmode. This is not a peace treaty option! It is a demand
that the nation return territory to you that is rightfully yours. The cost of sending your diplomats will depend on
the amount of territory involved, and although it does not increase your belligerence, it will seriously degrade
your relationship with that country regardless of whether or not it agrees to your demands.

Declare War

This option sends a formal declaration of war to another nation. Making a declaration of war without a casus
belli is a very belligerent action. Democratic nations will not even have this option available to them unless

the recipient of their declaration has either provided provocation, or has a very high belligerence value and
the democracy has a firm domestic policy of interventionism. While there is no monetary cost for declaring
war, doing so also risks civil unrest unless there is a very strong reason for the conflict. When you click on the
action, an interface will appear, informing you of the effect this will have on your national dissent level and
advising you of any allies that the target nation might have. If you wish to proceed, click the OK button. If you
change your mind, you may click Cancel.

A declaration of war will automatically plunge all allies of both nations into the conflict since they have no
choice in the matter, although they do not pay a political or domestic price for doing so. Once begun, war can
only be ended by concluding a peace treaty, or the elimination of all nations on one side of the conflict. The
subject of a declaration of war will also gain a small amount of sympathy from the international community,
resulting in a modest reduction of his belligerence value.

Democracy and Isolationism

A democratic nation with a strong domestic policy of isolationism will not be able to declare
war on another nation unless the target of the declaration has a very high belligerence value or
declares war against a nation whose independence you have guaranteed. Democratic isolation­ists will also be unable to join alliances or create new alliances unless that democracy is already

Sue for Peace

The sue for peace diplomatic option will only be
available if you are at war. There is no cash cost
to initiate this action and you may sue for peace
whether you feel that you are in a position of vic­tory, or one of defeat. When you sue for peace,
you will first be asked what type of peace you are
interested in negotiating. If you feel that you are
winning the war, select the “insist on demands”
button to assemble the terms of your enemy’s
surrender. If you are in a losing position, then you
may wish to select the “beg for peace” button to
put together a proposal of what you’d be willing
to give up to go to peace. If you would be content

with a return to the status quo before the war broke out, making neither concessions nor demands, then select

HEARTS OF IRON DOOMSDAY

the “white peace” button. Whichever option you select, a new interface will appear that will depend on what
type of peace you are pursuing.

Before we look at the options, it is important to understand the distinction between peace treaties negotiated
by an alliance leader and those that are negotiated by some other nation that is part of an alliance. This is
something that I touched on earlier when discussing alliances and bears repeating: When an alliance leader is
involved on one side of the negotiations in a peace treaty, any agreement that is reached is binding on every
member of that side’s alliance. If a nation that is not the alliance leader agrees to peace treaty, then it is only
that nation and not the alliance it belongs to that is bound by the agreement. The only peace agreement that
will end a war completely is one negotiated between the alliance leaders of the two sides that are at war. Any
other agreement will result in only a partial peace, with the extent of the peace being determined by whether
one of the nations involved in the negotiations was an alliance leader or whether neither of them was. Before
you offer terms or decide to accept an offer that is sent to you, be absolutely certain that you know what you
are agreeing to and who you’re agreeing to it with, or you could be in for a very big and potentially nasty
surprise!

When an alliance leader is involved in a peace negotiation it can arrange for one or more of its alliance mem­bers to be the beneficiary of any land being exchanged (they must currently occupy it for this to be possible),
but it can also force an alliance member to concede territories, if those provinces are occupied by the enemy.
An alliance leader cannot, however, bind an alliance member to any special peace terms such as forced disar­mament, military access, or forcing them to become a puppet of the enemy. Annexation - the worst possible
outcome of war for a nation - is not negotiated using the “sue for peace” option. It is a separate option and is
only binding on the nation that is annexed.

If you are pursuing a white peace, then you can simply click on the white peace option to send the offer. If
your enemy agrees to the proposal, all nations included in the peace will sign the truce and a peace treaty will
exist between you for the next five years. If a nation occupies any provinces that are owned by a nation that is
part of that peace treaty, these are returned to their rightful owner, but provinces owned by a nation that is still
at war will remain occupied. There will be no further compensation received by either side. I should warn you
that a white peace does not preclude a resumption of hostilities. War may be declared again by any nation at
any time, though with an added penalty for breaking the peace treaty, so this should be regarded as something
of a tenuous arrangement at best.

If you wish either to beg for peace or insist on demands, a somewhat different interface appears where you
will set the terms to which you are willing to agree. You will see a numeric evaluation of your current warscore
which reflects victories, defeats, conquered provinces and provinces lost to the enemy, and a variety of pos­sible peace conditions. Several special terms may only be included in the negotiations if you are insisting on
demands, and those terms will apply only to the nation with whom you are negotiating, not to any nations
that are part of that alliance. However, the overall interface will be generally the same in both cases. Each
peace term has a “value” and as you assemble your offer in the center area of the interface, these are tallied
at the bottom.

You can make multiple demands and can mix various types of terms to assemble your final offer. The possible
peace conditions include:

• Territory: You may specify territory whose ownership is to change hands if the peace is agreed upon. If you

are insisting on terms, you may only demand provinces that you currently occupy. If you are an alliance
leader, you may also demand provinces that are currently occupied by your allies and ownership would
transfer to your ally in that instance, and the recipient of each province that you demand is clearly indicated.
If you are begging for peace, you may also offer any provinces that you own, whether or not they are oc-

0

1

HEARTS OF IRON DOOMSDAY

cupied by the enemy. Note that all occupied provinces not included in the treaty will revert to their rightful
owners when the treaty is signed.

• Forced Disarmament: This option may only be demanded by a victor and cannot offered by a loser, and
may only be imposed upon the nation with whom you are directly negotiating and not one of his allies. If
the enemy agrees to this, he will be forced to disband his entire military.

• Military Access: This is another term that may only be demanded by a victor. If agreed to, this will give the
victor unrestricted access to move through the loser’s territory.

• Make Puppet: If you have a high enough war score, usually because you control many of the enemy’s
key provinces (identified by a red star in the victory points mapmode), you may demand that an enemy
submit to you and allow the establishment of a puppet regime in his nation that is loyal to your govern­ment. If accepted, the enemy will bequeath all territorial claims to your nation and a new government will
be installed that is of the same type as yours. The new puppet will leave any of its current alliances and
will join your alliance instead. It will automatically grant your country military access to their lands and
henceforth a portion of the puppet’s daily revenues will also be transferred to you as a sort of tribute or
war reparations. This is a fairly hostile action, although not as belligerent as outright annexation, and will
probably only be accepted if you enjoy vast military supremacy and the target nation feels that it has little
or no chance of survival otherwise.

Once you are satisfied with the terms, click the OK button to send your offer. I should caution you that an en-
emy is unlikely to agree to a proposal that is close to the exact warscore value and is much more likely to accept
it if there is large benefit to doing so. Certain nations will also be highly resistant to accepting any peace terms
beyond outright annexation with certain other nations, particularly the faction leaders. As with any diplomatic
option, it may take a day or two to receive a response and you will not be able to initiate further diplomacy
with that nation until at least one week has elapsed. If the peace is agreed upon, all nations involved in the
deal will sign the peace treaty which will be in force for the subsequent five years, but it is no more binding
that was the case with white peaces. Any territory that does not exchange ownership as the result of the terms
will be returned to its rightful owner.

Annex Nation

If you are at war with a nation and have achieved a crushing victory (you must occupy all of its key provinces
identified by a red star when viewing the main map in the victory point mapmode), the annex nation option
will become available. Annexation is the most devastating demand that you can impose and is treated as a
separate diplomatic peace option due to several special considerations related to its terms. The target nation
must lay down its arms and dissolve its government, surrendering ownership of all of its territories and for all
intents and purposes becoming part of your nation. This is always handled as separate peace, so even if the
defeated nation is an alliance leader it is in no way binding on any of its alliance members. There is no cost to
offer this “peace” but it is a demand that will remove that nation from the game unless it later reforms as a re­sult of partisan uprisings, and is considered the most hostile and belligerent action possible. Don’t expect your
demand to be accepted if the target nation still has some capacity to wage war, and if it is accepted, you should
expect other nations who are not very closely aligned with you to treat you as a pariah in the international
community for a long time afterwards. If you enjoy this high a margin of victory, you may wish to consider the
“puppet regime” peace term instead, one that will be considerably less damaging to your reputation, or some
other combination of highly punitive terms.

If an alliance leader is annexed, then a new leader will be chosen from amongst those nations that remain
and the state of war will continue to exist with that alliance. If there are no remaining alliance members, the
war will be over.

The Intelligence Folder

Overview

The Intelligence folder is a new feature, intro­duced to Hearts of Iron II with this Doomsday
expansion and is used to manage your clandes­tine operations. These include various missions of
industrial or technological espionage, fomenting
revolutions or even financing coups, the assassi­nation of prominent political figures, and other
such nefarious activities that are part and parcel
of the cloak and dagger world of the spy. It is also
your only source of information about the military
and technological capabilities of other nations.

network of spies. Some will be employed in your own nation to protect you from the efforts of enemy agents,
while others will be recruited in foreign nations to quietly gather intelligence or undertake more direct, hostile
missions. Successful actions can reap substantial rewards, but if a spy is detected, his life will be forfeit.

The layout and general interface actions of the folder are very similar to the ones used in the Diplomacy
folder.
1 Your Nation and Government: The top left corner of the folder will always display your nation’s flag and

name, as well as your form of government and current belligerence value. If you click on the flag, details
of your nation will be displayed in the rest of the interface.

2 World Nations: This is a scrollable list of all nations in the world that is almost identical to the one in

the Diplomacy folder. Beside each nation’s name, you will see a circle that indicates how many spies you
have currently operating in that country. The circle will be red if you have no spies there or if you your
spies are “sleeping” (see below), and will be green if they are “awake”. The information displayed in the
rest of the diplomacy folder will change depending on which nation you have selected from the list.

3 Selected Nation’s Diplomatic Details: This area is identical to the corresponding area in the Diplomacy

folder and will give a general diplomatic overview of the selected nation.

4 Selected Nation’s Industrial and Military Intelligence Summary: This area will display any industrial

and military intelligence that you know about the selected nation. If the nation is part of your alliance
then the information will usually be quite detailed, but if the country is neutral or an enemy, the
information will be less certain and could easily be inaccurate, out of date, or completely non-existent.
If you select your own nation, you will see a summary of the number of spies you have defending you,
and the total number of foreign spies you believe are operating within your borders.

5 Selected Nation’s Technology Intelligence Summary: This area will display any information you know

about the research projects currently underway in the selected nation. As with industrial and military
intelligence, this data will be accurate if the selected nation is your ally. If the nation is neutral or an
enemy, the information could easily be unreliable.

6 Intelligence Missions: This area contains a scrollable list of possible intelligence missions that you may

assign to your spies. The missions available to you will depend on the nation selected, and whether you
have any spies operating there.

As the game progresses, you will gradually hire a

HEARTS OF IRON DOOMSDAY

Mission Success and Detection

Whenever you attempt a spy mission, you will see an indication of the likelihood of the mission’s success.
This can depend on a large number of different factors that include the number of spies you have infiltrated
into that nation, the severity of the mission’s effects, the domestic policies of the target nation, the intel­ligence-related technology level of your respective nations, the difficulty setting of the game, and so on. If a
mission succeeds, the target nation will immediately suffer its effects. If the mission fails, one of the spies that
attempted it will be lost.

Each mission also has a chance of being “detected”. This governs whether or not the target will be able to
determine which nation attempted the action, and is checked regardless of whether the mission failed or
succeeded. It is therefore possible that you could be completely unaware that a mission has been attempted
against you or who was behind the assassination of one of your ministers. Successful detection does not kill the
spy but will usually result in a significant drop in the relationship value between the two nations. For some of
the more drastic actions such as assassinations, detection will have a global impact on the source’s relationship
with all other countries in the world, even its allies.

Gathering Intelligence

Until you have infiltrated another nation with at least one spy, you will have extremely limited information
available to you about the country unless you are part of the same alliance. Each spy you send will immediately
begin to gather intelligence data and report back with this information, and the more spies you can plant, the
more reliable and timely the data will be. The reliability is also affected by whether your spies are “sleeping”
or “awake” (see below), by various technologies, and by the domestic policy (open or closed society) of the
target nation.

Intelligence gathering is not a mission. It’s a “passive” activity that your spies will continue to do automatically
at all times. Once you have at least one spy in place, the intelligence summary areas of the folder will provide
the spy’s latest information about that nation’s military capability, its general production trends, and the tech­nologies that it is currently researching. Remember that the information could be unreliable or out of date.
Allies will accurately share most such information about their own nation to you, but they do not pass on their
intelligence data so you will need to infiltrate neutral or hostile countries with spies of your own if you want to
keep tabs on them. Remember that spies can be killed by failing a mission or as a result of counter-espionage
efforts, so your intelligence will likely fluctuate during the course of play.

Intelligence Missions

This section details the various missions that you can assign to your spies. Each mission has a cost and an
estimated chance of success associated with it, which will be reported in a pop-up confirmation box when you
select it. If you decide to proceed, the cash is immediately removed and your spies in that nation will attempt
to carry out their mission. Once your spies have attempted a mission, they will be unable to carry out any new
missions in that country for the following week.

Send Spy

Spies are recruited by selecting the nation in which you want them to work, and then choosing the “send spy”
option in the missions area of the folder. You can only send spies to neutral or enemy nations, or recruit one to
work in your own nation’s defence; you can never send one to a nation that is part of your alliance.

When hiring a spy in a neutral or enemy nation, you will be asked to confirm a one-time cost to assist the
agent to infiltrate the country, and you will be given an approximate idea of the likelihood of success. The

HEARTS OF IRON DOOMSDAY

primary factor affecting this is the domestic policy of the target nation, although this may be modified by other
things such as technologies, ministers, and whether you are at war or not. If your attempt is detected regardless
of whether it succeeds or not, your relations with that nation will suffer.

After successfully infiltrating a nation, a spy will begin to report intelligence data to you but will be unavailable
for any missions until a week has passed. He will be treated as “awake” during that week, so the intelligence
you receive will be more accurate, but he will be more vulnerable to any counter-espionage efforts.

You may also recruit spies in your own nation, an action that always succeeds. They will be your defence
against enemy agents, and can only be used for one mission: the counter-espionage attempt (see below).
They do not affect any intelligence data that enemy spies are gathering, nor do they reduce the likelihood of
an enemy mission’s success or detection. You must also wait a week before you will be able to hire another
defensive spy, or before your spies will be able to attempt any counter-espionage activities.

Sleep Spies/Wake Spies

Spies that have infiltrated another nation may either be “asleep” or “awake”. When awake, they will pro­vide far more accurate information but are much more likely to be caught by defending spies engaged in a
counter-espionage attempt. A sleeping spy is far more difficult to catch, but also provides much less reliable
intelligence. Only spies that are awake are permitted to carry out any missions, so a sleeping spy’s function is
strictly limited to gathering intelligence.

While sleeping or waking, your spies have no associated cost and are automatically successful, though a full
week must pass before they can be given a new mission. This means that if your spies are sleeping, you will
first need to wake them, then wait a week, then give them their mission, and then wait for another week until
you can order them to sleep again. During this two week period, they will be considerably more vulnerable to
counter-espionage missions.

Counter-Espionage (with Home Nation Spies)

Counter-espionage is the only mission that you can give to spies that you have recruited to defend your own
nation, and it is the only purpose for hiring them. When you issue this mission, your spies will attempt to flush
out any foreign spies that have infiltrated your country. Each of your spies will independently try to discover a
random enemy agent, and each spy that succeeds will kill one enemy spy. The number of spies doesn’t affect
the chance of killing an enemy spy; it only increases the number of attempts. If one or more of your spies
fails, you will lose one and only one spy. This means that if you have ten of your own spies at home, giving
them a counter-espionage mission could result in the death of up to ten enemy spies, at the risk of losing
only one of your own.

Success will depend primarily on whether the enemy spy is sleeping or awake, although other factors such as
your domestic policy (closed societies find it easier to catch enemy spies), intelligence technology, and your
ministers will also have an effect. Since this is an expected and normal part of national defence, there is no
effect on your relationship with other nations if your attempt is detected.

Counter-Espionage (in Foreign Nations)

The cloak and dagger game of counter-espionage can also be done by spies that you have sent to other
nations, but the mission is slightly different. In this case, your spies will make one collective attempt to kill one
of that nation’s defending spies, and the chance of success increases with the number of spies that make the
attempt. A success will kill one enemy spy, and a failure will result in the death of one of your spies and will
hurt your relationship with that nation.

HEARTS OF IRON DOOMSDAY

Sabotage Industry

This is a mission that attempts to delay an enemy’s production. If successful, one of the orders in the target’s
production queue will be set back significantly and any gearing bonus it receives will be reset to zero. A failed
attempt will cost one of your spies his life, and detection will harm your relationship with that nation.

Nuclear Sabotage

If your enemy possesses nuclear weapons, you may try to destroy one by ordering your spies to make a
nuclear sabotage attempt. If you succeed, a random nuclear weapon will be destroyed, though this won’t
cause it to detonate in its current location. Note that this does not target nuclear test facilities, and the option
will be greyed out if there is no weapon to sabotage. Failure will result in the execution of one of your spies,
and detection will have a serious impact on your relations with that nation.

Sabotage Tech Team

Instructing your spies to carry out this mission will attempt to set back one of the target nation’s research
teams’ progress on a research project. If there are several projects under way, they will generally try to disrupt
the one that is nearest completion, although there is a component of this selection that is random so the
amount of damage it will do can vary. Detection will harm your relations with that nation, and the scientists will
lynch one of your spies if the mission fails.

Steal Blueprint

This mission attempts to steal the blueprints for a technology that you have not yet researched but is known
by the selected nation. You will not know for certain that such blueprints exist, but if you have been closely
monitoring the intelligence data about their research, or you have seen other indicators such as advanced
military equipment, or perhaps a nuclear or rocket test facility that lead you to believe that they are a step
ahead of you, then it may be a very worthwhile mission to attempt. If your spies succeed, you will then be able
to use those blueprints to greatly reduce the amount of research your own teams will require to duplicate the
achievement. If they fail, you will lose one spy, and if your attempt is detected, your relationship will suffer.

Smear Campaign

Your spies may be given a mission to conduct a smear campaign in the target nation. If they succeed, the
public will believe these lies and that nation’s dissent level will rise. Detection will seriously damage your rela­tions, but will not have global repercussions. Failure will result in the death of one of your spies.

Fund Partisans

This mission instructs your spies to supply funding to any disgruntled civilians in a specified province in an
attempt to spark a local rebellion. You will be asked to specify the province where they should concentrate their
efforts and success will be affected by the existing level of dissent and partisanship in the area. It goes without
saying that this will cost a spy his life if the attempt fails, and if your nation is detected as the source of this
funding, your relationship with that country’s government will suffer a serious setback.

Assassinate Minister

This is a very dangerous mission that can have serious international repercussions if your involvement is
detected. When you issue the mission, you will be asked to specify which minister is the intended target. If
the plot succeeds, the minister will die; if it fails, one of your spies will be killed. If the attempt is detected, all
nations in the world will be appalled by your ruthlessness, although your allies will generally be more under­standing if the assassination was directed towards an enemy’s minister rather than at a neutral nation.

HEARTS OF IRON DOOMSDAY

Coup

You may issue a mission for your spies to try to engineer a coup d’état in the selected country - an effort to
overthrow that nation’s government and replace it with one that is far more sympathetic towards your own.
Success will depend largely on the domestic policies and dissent levels of the target, and detection will not
only damage your relations with that country, but can also have broader implications on any other nation that
shares the same general ideologies. As usual, if you fail, not only will you lose the rather substantial amount of
money you’ve spent, but you will also lose one of your spies.

Global Manipulation

Your spies will attempt to influence the world’s opinion of the selected nation, hoping to make it seem more
dangerous than it really is. If they succeed, the belligerence value of the target will increase for a period of
time. Failure will result in the hanging of one offender (I’m running out of different ways to say that one of
your spies will be killed) and if the attempt is detected, there can be a global backlash, including an increase
in your own belligerence level.

The Statistics Folder

Overview

The Statistics Interface is primarily a means of quickly gaining and reviewing large quantities of global informa­tion and for comparing your nation’s progress to that of others. Each table of information relates to an aspect of
the game, including: general summaries, economic information, convoy summaries, technology and military
comparisons, a complete listing of your armed forces including their locations, strengths and combat stats, and
a place where you may view the full-length version of the history log. A large number of the tables have “hot
links” allowing you to double-click to jump to a specific unit or province, or have right-click menus that allow
you to conveniently issue orders or make changes without directly going to a unit or provincial location. Due
to the number of statistics sub-folders, their fairly self-explanatory nature and the limited overall size of this
manual (for game-packaging reasons in some markets), I cannot provide details for each of the sub-folders
in this text. Remember that some of the information presented in this folder is drawn from the intelligence
reports that your spies have collected, so some data may not be not completely reliable, or could even be
absent altogether - something that was not the case with Hearts of Iron II prior to the Doomsday expansion.

Selecting and Using a Statistics Sub-Folder

Each of Hearts of Iron II’s 20+ subfolders can be accessed by paging through them using the left and right
arrows at the top of each folder. You can also jump directly to the desired folder by selecting it from the drop­down list between the arrows. They are generally grouped into five distinct categories: Summary, Economic,
Technology, Military and History.

There are some fairly common features available in the statistics subfolders. In many cases, the column head­ers can be clicked to sort the data in the tables in ascending order according to that heading, and clicking it
again will reverse the sort order. Double-clicking on an individual line in a table will usually jump directly to and
select the item in question, such as a province, unit, leader or supply route. In some cases, you can right-click
on an item to display a context-sensitive menu that allows you to take a direct action from the subfolder.

When you have finished reviewing the information and leave the Statistics Folder or use the quick-jump
feature, HoI2 will remember the last statistics subfolder that you were viewing as well as the sort category
and order that you last used for that folder. When you next open the Statistics Folder, it will return to you that
exact same view.

HEARTS OF IRON DOOMSDAY

Combat - The Art Of War

General Overview

We now (finally!) come to the part of the manual that deals with combat, a section that is designed to famil­iarise you with the various combat interfaces and to introduce you to some basic strategies that are likely to be
successful in your games. Beyond the odd one-on-one struggle that may occasionally occur, combat is one of
the most complex systems of the game and can have the most far-reaching effects. If you approach it from the
“Oh, there’s an enemy force…I’ll attack it!” standpoint without taking any other factors into consideration, you
are very likely to lose not only the battle but also the entire war. Instead, you must consider variables such as
terrain, weather, supply, leadership and the operational capabilities of your forces if you are to achieve any last­ing success. This shouldn’t come as a surprise since this is a grand strategy game, but it will probably take some
time for you to gain a full understanding of combat’s intricacies…and quite a bit more to become a master of
the art of war. I will assume for this entire section that you are familiar with the contents of the previous sec­tions of the manual, thus allowing me to avoid redundant descriptions or being forced to go off on tangents.

You will notice that I avoid giving detailed unit descriptions in this section. This is due in part to space limita­tions but is largely because the characteristics of each unit will change many times during the game to reflect
the modifiers that new technological advances will give you. An overview of the basic details can be found in
the military subfolders of the Statistics Folder, and a more thorough description is included in the unit specifica­tions in the Production Orders interface. For individual units, though, the most detailed information is shown in
the Unit Details interface. The big advantage of using in-game information is that it reflects the actual statistics
of your units, including any modifiers.

The effectiveness of most armed forces relies on the real-life principle of a chain of command, and since you
can’t be expected to issue orders to every single NCO in your army in every single theatre of war, HoI2 imple­ments a command structure to help you. As we’ve already seen in the Diplomacy section of the manual, you
will have a national Chief of Staff and three subordinates: the Chief of the Army, the Chief of the Air Force, and
the Chief of the Navy. For human-controlled nations, these individuals will sit quietly behind the scenes and
allow you to issue your own orders, their primary function being limited to giving you a few select bonuses to
certain military areas, although you could think of them as being the ones who relay your orders to the troops
and see to their supply. Your role as a player is to wear the multiple hats of the combined Joint Chiefs of Staff
and issue orders to your army, navy and air force. Each of these branches of the armed forces uses a slightly
different set of rules, and so to avoid introducing too much confusion we will examine each one in somewhat
isolated detail before we combine them again. As you read, it is worth keeping in the back of your mind that
your eventual success will probably depend on using a combination of at least two - and occasionally all three

- branches when you are planning your attacks.

We’ll begin by looking at your land forces, since they are the units over which you have the greatest degree of
control and they are the only units that are capable of conquering a province. Once we’ve thoroughly explored
their various interfaces and controls, we’ll move on to the differences and similarities of the interfaces that you
will encounter and use to control your air forces and navies.

The Land Forces

Overview of Force Structure and Field Commands

Hearts of Iron II doesn’t allow you to control individual soldiers, nor will you see any house-to-house or
even town-to-town fighting as you play the game. Combats represent large-scale offensive and defensive

HEARTS OF IRON DOOMSDAY

actions, a scale where the struggles involve large numbers of men and equipment, and where the prize is
the control of an entire province. Your job is to plan ahead, prepare and position suitable forces, ensure their
supply, and then issue the necessary orders to your field commanders and entrust them to carry them out
to your advantage.

While the precise structure and size of armies in the WWII era varied somewhat from nation to nation, HoI2
abstracts and generalises this to avoid confusion and maintain ease of play. The smallest land unit that can be
directly controlled in the game is the division, a unit that represents many thousands of men or a large assem­bly of military vehicles (i.e. tanks, trucks or half-tracks). There is, however, a smaller unit size available in HoI2:
the brigade. These are specialised units that cannot operate alone and must be “attached” to divisions to pro­vide a bonus to some aspect of the division’s performance. Due to their cost, it is unlikely that you will attach
a brigade to every division, but you are able to reassign one by detaching it from its current division and then
attaching it to another. This is a somewhat disruptive process, though, and will take some time to accomplish.

Individual divisions may operate in isolation, but more often will be grouped together to form a “corps” or
“army”. You have complete control over the way that divisions are grouped and may arrange them in more or
less any combination or number that you like. The terms “army” and “corps” are simply a semantic distinction
that the game uses when automatically assigning names to forces, in that a smaller grouping is usually called
a corps and a larger grouping is called an army, but there is no functional difference between them beyond
their sheer size. This size, however, introduces one specific issue that is of vital importance: leadership. When
you issue orders you will select a force of whatever size and composition and then tell its commanding officer
what you would like the force to do. He will then arrange for that force to carry out your orders to the best
of their ability; however, their performance will depend on a large number of factors (the individual division
types, their level of technology, the terrain, the weather, and more) and most importantly on the rank and
skills of that commanding officer.

Field Command

For the sake of clarity, I will use the term “field command” or simply “command” throughout
the remainder of the Land Combat section to refer to any force on the map that is commanded
by an officer and that you can issue an order to, regardless of whether it is a single division, a
corps or an army

Each nation begins the game with a specific set of military officers that historically served in that nation’s
armed forces and were of high enough rank that they were at some point in charge of an entire division or
more of men. Each of these officers will either be in the officer pool awaiting assignment, or be pre-assigned
to command one of the forces that are present when the game first starts. As you create new forces either by
building new ones or by combining or subdividing existing ones, officers must be assigned to lead them. You
may maintain complete control over officer assignments or you may delegate this process to the computer
to take care of; think of it as letting your Chief of the Army oversee it. Each officer has several attributes that
will affect the performance of the troops he commands: his rank, skill, experience, and possibly also a special
area of expertise. Of these, the one to pay the most direct attention to is his rank, since this is the attribute that
determines the maximum number of divisions that he is able to handle before his field command will begin
to incur a combat penalty. Whenever more than one field command is operating within the same province,
there are additional considerations that will contribute to the outcome of the battle. This becomes somewhat
more complex when an operation is staged using multiple field commands, launching their attacks from
several different provinces.





HEARTS OF IRON DOOMSDAY

At the beginning of each game, you will have a certain number of pre-existing divisions that are based on the
approximate historical order of battle of that nation. For some countries, this could be quite a large number,
while for a few others it could possibly be none at all. Some of these may have brigades attached to them and
some may already be grouped into larger commands, and each will have a pre-assigned officer. Any further
forces you require must be obtained by placing a production order and waiting until they are ready for deploy­ment. When ready, they will appear in your force pool to await deployment. Divisions that engage in battle will
gradually gain valuable combat experience which will improve their capabilities over time. Unfortunately, they
are also likely to experience casualties that will need to be replenished with reinforcements. Raw recruits will fill
those vacant positions but will also dilute a division’s experience. Officers also gain combat experience which
can lead to improvements in their skill levels and might prompt you to promote them in rank. They may also
gain new, specialised “traits” that will improve their abilities under certain circumstances or conditions. It may
take them a little while to get used to this new level of command, so there could be a period of time where
they will not perform quite as well as they did prior to their promotion. Now that you have a rough overview
of the forces, let’s look at them in greater detail…

Division Types

Your divisions are used to defend your territories from enemy attack, or to launch offensives of their own to
conquer and then occupy enemy provinces. Only land forces are able to capture and hold an enemy province,
although their efforts will often need to be supported or assisted by air and naval units. While your air force
and navy may hinder an enemy advance, neither is able to defend a province, and so you will need to deploy
your land forces to protect them.

Divisions can be of a variety of different types, each one having its own specific advantages and disadvantages
which will vary depending on terrain, weather, and even the type of enemy they are facing. While there are
more than a dozen varieties, they can be classified in three broad categories: foot soldiers, mounted troops,
and armour, each of which I’ll describe in a moment. As your technology improves, each unit’s specifications
can also be improved, provided that you allocate sufficient IC to upgrade them with your most recent ad­vances. It is also likely that not all of the division types will be available to you at the beginning of a campaign,
since many require specific advances in equipment or achievement of a particular type of army doctrine. Check
the detailed descriptions in the Technology Folder to determine what is required for their production and then
instruct your scientists to work towards that goal if you feel that you will need that type of specialised combat
force in the future.

The most numerous and versatile unit is probably the foot soldier, with the most common type being the
infantry division. While they will find themselves at a disadvantage in the open, they generally perform better
than mounted or armoured units in less hospitable or obstructed terrains. Infantry is usually fairly inexpensive
to recruit, relatively fast to train, and does not consume any of your precious oil, though of course they won’t
move as fast as the other units.

There are specialist infantry types who perform particularly well in certain roles but are more expensive and
time-consuming to prepare. Marines are particularly effective for coastal invasions, mountaineers excel in hilly
and mountainous areas, and airborne infantry are the only units that may be used to attack from air transports.
If you are in desperate need of a quick influx of troops at low cost, you might find that a militia division’s gener­ally poor performance is sufficient, at least for a while.

Mounted units perform in much the same way that infantry do. The most basic of these is the cavalry division,
an obsolescent holdover that predates the First World War, but which was still used in some parts of the world.
Not surprisingly, they tend to perform very poorly against most other units and have few advantages other
than a more rapid rate of movement than foot soldiers. The majority of your mounted units will be infantry

HEARTS OF IRON DOOMSDAY

who use motorised vehicles, primarily trucks, to move more rapidly, though they are more expensive to outfit
and will consume a quantity of fuel. Motorised infantry are much more susceptible to aerial attack and will
run into difficulties where the roads are poor or terrain becomes an obstacle. Mechanised infantry divisions,
who use armoured vehicles such as halftracks, are very expensive and consume even more fuel, and remain
easier targets for enemy tactical bombers; however, they have better attack and defence capabilities than any
other infantry unit.

Infantry and mounted infantry are no match for tank divisions when it comes to sheer firepower and the abil­ity to withstand punishment. As your technology advances, you will have the ability to build larger tanks with
heavier armaments and armour which will further increase the amount of damage that they can both inflict
and sustain. Armoured units are expensive, though, and consume fuel at an alarming rate. They also perform
very poorly when the terrain is rough or filled with obstacles.

There are two other specialised division types that merit extra attention but are detailed later in this section.
A garrison division is a special infantry unit whose sole function is to suppress the activities of partisans. They
are highly restricted in their method of movement and are utterly unsuited to combat situations, but they are
unparalleled at maintaining law and order in any enemy provinces that you might occupy. The other unit type
is the headquarters division. These act as large mobile command and control centers, assisting very highly
ranked officers (generals and field marshals) to manage larger numbers of divisions, improve supply efficiency,
and provide improved combat capabilities for any forces that are in the same province or an adjacent one.
They are, however, a division that is primarily designed for tactical and logistical support and are not heavily
armed or suited to combat themselves.

Brigade Types

There are a variety of brigades that may be attached to your divisions to enhance their abilities; however,
each division may only have a single brigade attachment. A brigade’s area of expertise is fairly self-explanatory
when you review its details in the production interface. Note that the specific values are added to the abilities
of the division they are attached to, thus usually improving their performance quite significantly, although there
sometimes is a small trade-off in another area. Brigades may range from anti-tank to anti-aircraft specialists,
or may be able to support your divisions by providing withering artillery or even rocket fire. Engineers will
improve both the defensive capabilities and movement rates of your divisions, while additional armour can be
attached to bump up the attack strengths of a force. The available brigade types will depend largely on what
technologies you have researched, as will their effectiveness.

A brigade is created in exactly the same way that a division is ordered, but they are never deployed by
themselves. Instead, brigades must always be attached to a division - which is determined at the time that
it is deployed from the force pool - although they may later be detached and returned to the force pool for
subsequent redeployment elsewhere.

Division Details

Before we look at deployment or movement, or begin assembling corps
or armies, let’s take a close look at the details of an individual division and
the meaning of each of its specifications. These can be seen for any unit
by first selecting any field command and then selecting the division that
you are interested in reviewing. Select any field command by clicking on it
on the Main Map, using the Land Forces Hot Button, or via several of the
subfolders in the Statistics Folder. The information panel will then display
the name of the commanding officer and a list of the divisions in his com­mand (we’ll come back to the Field Command Details display shortly).
Clicking on any one of the listed divisions will display the Division Details
for that unit in the information panel, as well as giving you a few options
for that specific division.

• Division Name: At the top of the information panel, you will see the
division’s name. While this is assigned automatically when the division
is first created, you can change it any time you like by clicking on the
unit name and then typing a new name.

• Division Type: Below the division name, you’ll see a picture and then a
description of the division type. The specific model represented by the
division will follow in parentheses.

• Brigade Attachment: If there is a brigade attached to this unit, the
brigade type and model names will appear immediately below the
division name. There will also be an inset picture of the brigade in the

• Commander: You will see a picture of the division’s current commanding field officer. Remember that this
officer may command a number of divisions if they are grouped together into a corps or army. Clicking on
the officer’s portrait or anywhere in this field command summary bar except the Orders Box will return you
to the Field Command Details display in the information panel.

• Command Strength and Organisation: Beside the commander’s picture is a graphic display of the per-
centage strength (orange bar) and the percentage organization (green bar) of the entire field command.
This is the average of all forces under that leader’s command, so it may be different than the individual
division’s values if it is presently part of a larger command. Again, you can click almost anywhere in this
area to return to the Field Command Details instead.

• Command Name and Size: Beside this, you will see the name and the number of divisions in the field
command.

• Command Orders Box: The command’s current mission is displayed in the Orders Box immediately be-
low its name. You may click on this box to issue new orders directly from this interface or cancel its existing
orders. Note that doing this will update the orders for all divisions in this field command.

• Location Details: Below the command bar is a second bar that indicates the current location of this division.
This is the same bar that is displayed for each province in the information panel when you click the Prov­ince Hot Button. You will see the province name, IC, resources and the total number of divisions, including
allies, presently located in this province. Clicking on this bar will close the Division Details and display the
Province Details in the Information Panel instead.

• Strength: This is a division’s current operational strength. When first built, it will be at 100% but can then
be reduced as a result of combat casualties or attrition losses. If a division is in supply, then it will gradually

lower right quarter of the division’s picture.

HEARTS OF IRON DOOMSDAY

replenish to 100% as long as you allocate some of your IC to reinforcements. If the strength ever drops to
0%, the division will be destroyed. As a division’s strength is reduced, the amount of damage it will inflict
on an enemy is also reduced by a corresponding amount. Regardless of how fantastic its other combat
values might be, a unit that is near destruction will contribute very little to a battle.

• Organisation: This is the division’s level of organisation, reflecting its internal command structure, intrinsic
cohesiveness, and readiness to fight. There are two numbers displayed: the current organisation and the
maximum organisation of the unit. Although expressed as a percentage value, it might be more appropriate
to think of it as a capped index value instead. Early in the game, the maximum achievable organisation level
of a division will rarely exceed much more than 40% or 50%, but you will be able to reach much higher
levels as your technology advances. Domestic policies and your Chief of Staff and Chief of the Army may
further increase a division’s cap, even allowing it to exceed the 100% mark. Organisation may be lost as a
result of bombardment, prolonged movement (particularly in poor terrain), and during combat. It will also
plummet if your troops are out of supply and will be fairly low when divisions are first deployed and when
they are strategically redeployed over great distances. If organisation drops below 5%, the division will lose
its ability to fight and will try to withdraw. Organisation is regained when a division is in supply and remains
stationary and out of combat for a period of time. The infrastructure of a province, which affects the ef­ficiency of supply, and the morale of a division will also have an effect on the rate of regain or loss.

• Morale: Each division has a morale value that represents its willingness to persevere in the face of adversity
and is similar in almost all respects to organisation. It, too, will rarely approach or even exceed 100% until
very late in the game, when a division’s experience and your nation’s technology will boost the maximum
level that a division may attain. As long as a division is in supply, high morale will allow it to perform better
in combat, reduces the rate at which it loses organisation during combat, and increases the rate at which
organisation is regained. Morale is slowly lost during combats and will drop rapidly if a division is out of
supply. Once it approaches or drops below 30%, it will actually cause the rate of organisation loss to ac­celerate. Should morale reach 0%, your division will break and run in utter disarray.

• Softness: Each division has a “hard” and “soft” component to its strength. The hard portion is its armour
(tanks, trucks, machinery, etc.) while the soft component is its personnel. The softness value indicates the
percentage of a division’s makeup that is considered as a soft target. This has a significant effect on the
types and degree of damage that different types of enemy units will inflict during combat. An infantry divi­sion will usually have a softness value of nearly 100%, while a tank division has a far lower value, probably
around 30%.

• Hard Attack: I’ll describe the specific meaning of attack and defence values in detail when we look at the
actual mechanics of combat, but roughly speaking, this value indicates the attack power of the division
when engaging an enemy division that has a fairly large “hard” component (i.e. a low softness value). The
higher the attack number, the more likely it is that it will inflict some damage to a “hard” target such as a
tank division.

• Soft Attack: This value indicates the general attack power of the division when engaging soft targets. A
high number here indicates that it probably do well against divisions that have a high softness component,
such as infantry divisions.

• Air Attack: When a division is attacked by aerial units, it may have the ability to fight back and inflict some
damage. The air attack value indicates how well it is able to do this and will be fairly good if the division
has an anti-air brigade attached.

• Defensiveness: The division’s defensive capabilities are divided into two components: defensiveness and
toughness. The defensiveness value is used when a division is defending a province against an attack initi­ated by an enemy. Roughly speaking, the higher the value, the better the division will be at withstanding

2



HEARTS OF IRON DOOMSDAY

enemy fire.

• Toughness: This is the second component of a division’s defensive capability and is used when the division
is launching an attack of its own against another province. A high value indicates that it can withstand more
of the enemy’s return fire as it makes this assault.

• Air Defence: This value indicates how well a division is able to defend against enemy tactical bombing
attacks. This value is mostly an indication of how difficult a target is to hit and how resilient it is. It does not
imply an ability to fight back.

• Suppression: This is an indication of a division’s basic capabilities at suppressing partisanship in a province.
The value is subtracted from the province’s partisan value, which determines partisan effects and activities,
and can be further enhanced by giving the unit orders to engage in anti-partisan activities, which doubles
the effective suppression value.

• Maximum Speed: This is the maximum speed that the unit can travel in clear, unobstructed terrain. This
will be reduced in less hospitable terrain or inclement weather.

• Supply Consumption: The supply amount that this division needs on a daily basis is listed here and will
fluctuate depending on the current strength of the unit. Note that this is the amount of supplies it requires
and is not necessarily the amount it is receiving.

• Fuel Consumption: Any division that uses vehicles of any sort will require a daily supply of fuel (oil) equal
to this value if it is currently moving or if it is engaged in combat. A stationary unit that is not engaged in
combat only uses a portion of this amount. Fuel consumption is also dependent upon the current strength
of the division.

• Experience: Each division gains combat experience whenever it engages in battle. An experienced unit will
receive combat bonuses and tends to maintain its organisation and morale far better than a division filled
with recruits. When any casualties that a division sustains are replaced through reinforcement, the newly
recruited men will dilute the division’s experience level.

• Effective Supply Efficiency: This is the division’s current rate of supply efficiency which is determined by
a large number of factors, which will be explained in the subsection on Transport Capacity and Supply
Efficiency. Roughly speaking, this indicates whether a unit is fully supplied or whether it will be subject to
some penalties for being undersupplied.

• Attach/Detach Brigade Button: If the division currently has a brigade attached to it, then clicking on this
button will detach the brigade and return it to the force pool. If the division does not have a brigade at­tached to it and a suitable one is available in the force pool, clicking on this button will allow you to select
and attach a brigade from the force pool.

• Disband Button: Clicking this button disbands the division and returns some of its manpower to your
national manpower pool.

Remember that not all units of the same type will have the same division stats, since these are dependent on
whether or not a division has been upgraded to the latest technology. Any brigade that is attached to a division
will also have its abilities added to the division’s stats reported in the information panel. Several of the division
stats will also be modified by the unit’s experience level and by the abilities of the commanding officer, the
source of yet further discrepancies between two otherwise identical divisions.

HEARTS OF IRON DOOMSDAY

Field Command Details

Corps and armies are created by grouping divisions into a larger fighting
force: a field command. Before we look at how to do this, let’s have a look
at the information you’ll see when you select a typical field command, a
summary of the divisions that make up the command and their most
critical statistics. Due to space limitations in some of the game menus, the
word “unit” is frequently used in tooltips and orders to refer to a field
command.

• Command Name: The name of the field command appears at the
top of the information panel. As was the case with individual divisions,
the command name is assigned automatically based on size and na­tion but can be changed by clicking on its name and then typing in a
new one.

• Commander: The portrait and name of the officer who is currently in
command appears just below the field command’s name. Clicking on
the officer’s portrait will allow you to select a new commander from
the pool of available leaders. Hovering you mouse over his portrait will
display the officer’s stats. Details of how to change an officer and the
meaning of his stats are described in a later subsection.

• Overall Size, Strength and Organisation: The number of divisions
of the field command is listed immediately below the commander’s
name. If this number is red, there are more divisions than the com­mander’s rank would normally permit. Divisions will suffer combat
penalties and any leadership trait advantages will be lost. In brackets
beside this is the total force strength and their average level of or-

• Current Mission: The current mission that this command is engaged in will be listed in a small box. Click-
ing here is one of several ways to change their mission. Details about missions are also described in a
later subsection.

• Current Speed: The speed that this field command can currently achieve if it moves is displayed just below
the commander’s picture. This is determined by the slowest-moving division in the group, as modified by
the current terrain and weather conditions.

• Quick Status Icons: A variety of icons may appear in the space below the mission box. Most relate to the
command’s current conditions of supply, whether they are dug in or not, and so on, with tooltips identify­ing each them.

• Supply Source: If the field command is in supply, the source of that supply will be listed. If it isn’t, you will
see a warning to this effect, as well as the location from which it is attempting to draw supplies.

• Command Location: You will see the current location of the field command. Clicking on the location box
will display the province information panel. If this field command is currently engaged in battle, this display
will change quite dramatically, showing the “Combat Quick View” summary instead. This is similar to the
summary that you will see for each battle when you click the Active Combats Hot Button.

• Effective Supply Efficiency: This is the field command’s current effective supply efficiency. Details are to
follow shortly, in the Transport Capacity subsection.

• Division Listing: The majority of the information panel below this point will display a scrollable listing
of each division that is currently part of this command. Clicking on one of the divisions will display the

ganisation.





HEARTS OF IRON DOOMSDAY

Division Details information panel, described in the previous subsection. Each division will also display the
following basic details:

• Division Type: An icon indicating the type of division (infantry, mech. infantry, etc.) and its technology
level.

• Strength Bar: A red bar that indicates the division’s approximate strength. If you hover over this bar, a
tooltip will appear that displays the exact numerical strength value.

• Organisation Bar: A green bar that indicates the division’s approximate organisation. This, too, has a tooltip
that will give the division’s exact numerical organisation value.

• Fuel Status Icon: A small oil icon below the strength and organisation bars will show the division’s fuel
supply status. This will be blue if the division is in supply and red if it isn’t.

• Division Name: The division’s name.

• Division Main Stats: Below the division name, you will see a summary of the five main division statistics

that you will refer to most often. In order, from left to right, these are the Hard Attack, Soft Attack, Air Attack,
Defensiveness, and Air Defence values.

• Brigade Icon: If there is a brigade attached to the division, there will be an icon at the right edge of the
division listing to indicate that this is the case and what type of brigade it is.

• Prioritized Button: It is possible to assign a priority to a field command to ensure that divisions in this
command are the first to receive any available reinforcements and upgrades. Click this button to toggle
between giving this field command that special priority or not.

• Reinforcement Button: You can elect whether to allow reinforcements to be sent to replace any casualties
suffered by this field command by clicking this toggle button. You might wish to do this if manpower is in
short supply, or if you don’t want to dilute this unit’s experience by adding in new recruits. Of course, this
means that any casualties will reduce its operational strength and combat potential.

• Upgrade Button: You may prevent a field command from being outfitted with any new technological
upgrades. Normally, you would do this only if you intend to scrap it soon, or if it is in danger of being
destroyed.

• Offensive Button: This allows you to allocate additional fuel and supplies to this command for a major
offensive. This boosts the supply efficiency by 25% for the next 30 days, but will consume a large amount
of supplies and fuel. Details of supply and supply efficiency are in a subsequent section.

• Load Button: This is a quick way to issue an order for the entire command to be loaded onto transport
vessels if they are present and sufficient space is available. The load button will not be displayed unless you
are in a province that contains a port or naval base.

• Reorganise: Clicking this button opens an interface that allows you to easily remove divisions from this field
command and assign them to a separate command that will be created.

HEARTS OF IRON DOOMSDAY

Field Officers

The officer that you assign to lead a field command will have a significant effect on the performance of your
troops in battle. Each nation begins with its own pool of officers that can be assigned to command its forces,
each possessing one of four possible ranks as well as his own unique characteristics. As a commander’s
forces participate in battle, he will become progressively better at his job and may eventually be suitable for
promotion.

• Skill: The skill of an officer indicates his overall performance ability. As he gains more and more combat

experience, he will gradually increase in skill level. This confers a special combat bonus on his troops that
increases as his skill increases. An officer who is overstacked cannot effectively command his troops and
any skill bonus he provides will be ignored for all of his forces. When you promote an officer, his skill is
reduced by one level. This penalty is not applied if you use the auto-promote option (see below).

• Historic Skill: There is also a value relating to each officer’s skill that is buried within the game design

(shhhh…don’t tell the designers that I told you this secret!) and reflects the individual’s historic accom­plishments. The historic skill level acts as a modifier to the rate at which he will accumulate experience. If
he is significantly below his historic levels he will tend to accumulate experience much more rapidly, and
once his skill exceeds this he will tend to be much slower in accumulating more. This is a modifier and
not a cap.

• Experience: Each time an officer commands a force in battle and is victorious, he will gain a small amount

of experience. Eventually, he will gain enough experience to increase his skill level by one point. The rate
at which an officer accumulates experience depends on his rank and how often he is in combat (and: shh­hhh!: his historic skill rating). The higher an officer’s rank, the more slowly he will gain experience.

• Trait: Each officer may have a particular doctrine or area of expertise that is listed at the bottom of his

stats. These traits, described in the next subsection, give special abilities or bonuses that are applied to any

When you select a field command, the current commanding officer will be
identified at the top of the information panel. If you hover your mouse
over his portrait, a tooltip will display his personal stats and clicking on his
portrait will show your officer pool, which contains a detailed list of all of­ficers that are currently unassigned to commands. If you click on any of­ficer in this list, he will be assigned to replace the current field commander
and the existing commander will be returned to the officer pool. Each of­ficer has five personal values:

• Rank: An officer’s rank determines how many divisions he can effec-
tively command without incurring penalties in his divisions. There are
four distinct ranks used in HoI2: Field Marshal (commands up to 12
divisions), General (9), Lt. General (3) and Maj. General (1). If he com­mands more than this number of divisions during an attack, he will be
considered to be overstacked. A field marshal or general whose army
includes an HQ division will also enjoy a large command bonus as well
as several other benefits. You can promote an officer to the next rank
if he has a skill rating of at least one. This will enable him to control
more divisions but will reduce his current skill level by one and will
reduce the rate at which he will gain further experience. This is done
by clicking the promote button. If you use the “auto-promote” option
(see below), the skill reduction penalty is waived.





HEARTS OF IRON DOOMSDAY

division that is directly under his command, unless he is overstacked, in which case they are forfeited for all
divisions. Officers may also gain new traits as a result of special game events that occur during battle.

Beware of overstacking an officer! It is probably the single most damaging thing you can do to your chances
of winning a battle. An officer who is overstacked forfeits all bonuses that his traits and skill would normally
give to the divisions under his command. Further, the “extra” divisions that are assigned to him will be subject
to an additional, severe combat penalty.

You may, if you wish, delegate the task of assigning and promoting officers by clicking the Auto-Promote
or Auto-Assign leader buttons at the bottom of the officer selection interface. If you do so, your Chief of the
Army will see to these functions as best as he is able. If you are using this function, the officer assignments are
checked and updated at midnight each day, based on the number of divisions the officer currently commands.
When using Auto-Promote, leaders do not lose one point of skill when promoted by the Chief of the Army.

If you have a very large number of field commands, it is possible that you will exhaust your pool of historical
leaders. If this happens then “generic” officers will be created as required, although they will be of very poor
quality, will not gain experience, and will “disappear” again once removed from command. In that situation,
you may need to remove a historical leader from one command, thus returning him to the pool and replacing
him with a “generic” officer, and then assign him to a new command that is in more urgent need of his abilities.
When a division is first deployed from the force pool, it will also be commanded by a generic officer unless it is
deployed directly into an existing command. Don’t forget to assign a “real” officer to any division that is likely
to see combat action as soon as possible.

Field Officer Traits

A field officer may have specific traits that will characterise his style of command or identify areas where he
possesses exceptional abilities. If he has such a trait, it will be identified in the tooltip that appears when you
hover your mouse over his portrait and will benefit any divisions under his direct command. Warning! This
bonus is lost if the officer is overstacked.

• Logistics Wizard: This officer is able to achieve impressive economies of both supply and fuel efficiency.

Divisions under his command will consume both at a reduced rate.

• Defensive Doctrine: This officer is very good at preparing his troops to defend against enemy attacks and

counter-attacks, improving their defensiveness and toughness values.

• Offensive Doctrine: This officer is very good at manoeuvring his forces to gain maximum tactical advan-

tage, giving them bonuses to all attack values.

• Winter Specialist: This officer excels at winter warfare, guiding his forces with such skill that they incur no

penalties to movement or combat in those conditions.

• Trickster: An expert at camouflage and deception, divisions under this officer’s command will always gain

the advantage of surprise, are very difficult for enemy aircraft to target, and are usually completely invisible
to enemy intelligence activities.

• Engineer: Divisions under the command of an engineer are able to cross rivers without incurring the normal

movement or attack penalties that other units will suffer.

• Fortress Buster: This officer is particularly good at assaulting enemy fortifications.

• Panzer Leader: A panzer leader is able to increase the movement speed of his forces, and if he commands

predominantly armoured divisions, he is able to improve their attack abilities and may even achieve sud­den and devastating victories by blitzing through enemy lines.

• Commando: This officer is best suited to lead mountaineers, marines or paratroopers, who receive large

bonuses to both their attack and defensive values when under his command.

• Old Guard: This officer is of the old school and not particularly imaginative. Neither he nor the divisions

HEARTS OF IRON DOOMSDAY

under his command will learn as much during combat, thus reducing the rate at which they will gain
experience.

• Desert Fox: This officer gains special bonuses to combats occurring in the desert.

• Jungle Rat: This officer gains special bonuses to combats occurring in the jungle.

• Urban Warfare - This officer gains special bonuses to combats occurring in urban provinces.

• Ranger: This officer gains special bonuses to combats occurring in the forest.

• Mountaineer: This officer gains special bonuses to combats occurring in the mountains.

• Counter-Attacker: This officer is highly adept at absorbing an attack and then making a counter-attack of

his own. This will increase the chance that a counter-attack event will occur during a battle that favours his
force. Combat events are discussed in a later section.

• Assaulter: This officer is particularly good at making direct frontal assaults. The increases the chance that an
assault event will occur for his side during a battle.

• Encircler: This officer excels at encircling an enemy, increasing the chance of this favourable combat event
firing during a battle.

• Blitzer: This officer can achieve amazing results through small-scale blitzes of the enemy position. The blitz
combat event is far more likely to occur when he is in command of a force.

• Disciplined: This officer is able to maintain discipline within his forces, greatly increasing the chance of
receiving a “delay” combat event during a battle.

Selecting and Organising Field Commands

Selecting a field command can be done in a variety of different ways:

• Click on its sprite on the Main Map. If there is more than one field command present in the province, you
will see a series of small bars appear below the sprite. Repeated clicks will cycle through the field com­mands in the province or you can click on one of the small bars to select a specific force.

• Left-click and drag your pointer to highlight a portion of the map. When you release the mouse button, any
command that is inside the highlighted area will be listed in the information panel, at which point you may
then simply click on the command to select it from the list.

• Click on a province on the Main Map to display a list of the field commands located there, then click on the
command in that list to select it.

• Click the Land Forces Hot Button and then select one of the field commands from the list of all commands.
This will also center the map on that command’s location.

• You may also use a number of the tables in the Statistics folder to select a command by double-clicking on
the unit’s name in the chart.

• Hold down the Shift key on your keyboard to select multiple field commands, which don’t have to be in the
same province. If you click on a selected command while doing this, it will be de-selected.

• Note that the "left-click and drag" method will also select multiple commands.

You can merge multiple field commands into a single new force if they are all located in the same province.
To do this, select the field commands you want to merge using one of the above methods and then click the
Merge button at the bottom of the information panel. Remember that the highest ranking officer will assume
command of this force, while all other commanders will be returned to the leader pool. If you have elected to
select your own officers, don’t forget to check that he is capable of leading the total number of divisions that
you have assembled and replace him if necessary. If you are using auto-assign for officer assignments, you
should wait until after midnight to issue orders to them. This is because your Chief of the Army will not change
officer assignments until midnight, and if a field command is currently carrying out a mission or is in the midst
of combat, he will not change the officer assignment.





HEARTS OF IRON DOOMSDAY

You can split a field command into two separate commands by selecting the force and then clicking the
Reorganise button in the information panel. A list of each division in the existing command will be displayed
in the information panel. Click the small “+” button beside any division that you would like to remove from
this command and add to the new one. If you are allowing the Chief of the Army to place leaders for you,
he will assign an appropriate officer from your leader pool to take command, who will assume command at
midnight. If you have chosen to assign your own officers, this new force will be commanded by a “generic”
leader, so don’t forget to assign a more competent leader after creating the new force, assuming one is avail­able in the officer pool.

Shortcut Keys

Hearts of Iron II allows you to assign up to ten different force selections for rapid access at a later time by us­ing a shortcut key. To set the assignment, select any division, field command or even multiple field commands
using the method described above. While they are selected, hold down the Ctrl key on your keyboard and
press any number key on your keyboard (not on your numeric keypad). You may return to that selection at any
later time by pressing the number key once more without holding down the Ctrl key; pressing the number key
a second time will center the map on that selection. You may also use this same technique for your air forces
and naval forces, and up to a total of ten such selections may be stored. If you assign a new selection to a
shortcut key that already has an assignment, the old assignment will be overwritten by the new one. While this
feature is mostly a matter of convenience, it is vital in multiplayer games where your house rules discourage or
even forbid pausing the game since you can set up these shortcut keys to allow you to quickly jump to major
theatres that are separated by a considerable distance.

Deploying Divisions from the Force Pool

When a production order has been completed, the newly created division will be placed in the force pool to
await deployment. Begin by clicking on the Force Pool Hot Button to display a list of all forces that await deploy­ment and then select the unit you wish to deploy. The main map will change to display all valid deployment
locations in green and the information panel will now display a list of any field commands to which the unit
can be added. If you click on a province on the map, the division will be placed there. If you click on a field
command, the division will be added to that command. In both cases, this happens immediately.

You should deploy new forces fairly promptly in most cases because they will not begin to gain organisation
until you do so, nor will they be upgraded to take advantage of any technologies you might have finished
researching from the time that the production order was initially placed. There is also no supply-consump­tion advantage to leaving a force in the pool, since it will consume its daily requirement whether it has been
deployed or not. It will also tie up 2 points of transport capacity (see below) until it has been deployed.

Attaching Brigades

Attaching a brigade can be done in almost the same manner as adding a new division to an existing field
command. There is one additional step, however, since you must identify which division in that command is
to receive the brigade. A second method of attaching a brigade - and the one that I would recommend for
ease of deployment - is to locate the division that you wish to attach it to first, click the attach brigade button
to display any brigades that are currently available in the force pool, and then simply click on the brigade to
attach it. You may only attach one brigade to each division, and there are limitations to the type of brigade that
a division may accept, generally requiring that they be of a similar overall type of unit.

Transport Capacity and Supply Efficiency

Now that we’ve looked at the internal details of divisions and commands and how to deploy new ones, let’s

HEARTS OF IRON DOOMSDAY

look at the next important component of a successful military venture: supply. To do this, we must first look at
the subject of your nation’s transport capacity and supply efficiency.

As you may recall from the Production section, transport capacity (TC) is an abstraction that Hearts of Iron
II uses to represent a nation’s overall ability to move goods and materials. It is the product of your nation’s
industrial capacity as modified by available technologies, and is consumed by sending supplies and fuel to
your armed forces. It is also used by any items currently awaiting deployment from your force pool and by
any divisions that are being strategically redeployed. A further drain is placed on TC by each enemy province
that you occupy. As long as you are careful to ensure that the total available transport capacity exceeds your
total use of that capacity, you should run into the fewest possible problems when it comes to supplying your
troops in the field.

Supply Efficiency at a Glance

BSE = Total TC / Used TC (up to 100%)
ESE = BSE x province infrastructure
(ESE affects movement, attrition, effective strength, and effective organisation values)

If you hover your mouse over the TC icon in the Top Bar, you’ll see a breakdown of your current TC usage
and below this you’ll see your base supply efficiency (BSE). This is the theoretical maximum efficiency that you
could achieve under ideal conditions, although this is modified by the local infrastructure for troops in the field,
representing the ability to deliver supplies to those units.. The effective supply efficiency (ESE) is therefore the
base supply efficiency modified by the amount of infrastructure in the province. This can be further reduced
if an enemy bomber force is conducting certain types of bombing campaigns against the province. These
missions are detailed in the Air Combat section.

Because of its wide-ranging effects, it would be hard to over-emphasise the importance of the effective supply
efficiency value. A division that is located in a province with low ESE will suffer increased attrition rates, reduced
movement speeds, and will take much longer to upgrade or to regain its strength and organisation. During
combat, low ESE will also tend to result in more rapid loss of morale and organisation, making it more likely
that your forces will break off their attack more quickly and will sustain higher casualty rates. When combined
with other possible modifiers due to terrain, weather, climate and enemy logistic strikes, this could easily result
in a persistent rate of loss that makes it virtually suicidal for a division to remain there.

Only two things can be used to offset this potentially devastating effect. A headquarters division has the effect
of noticeably increasing the ESE for all divisions within a one-province radius of its location. You can also use
the option of placing a field command on the offensive, which will increase their supply efficiency by 25% for
the next 30 days but will double the amount of supplies they consume.

Attrition

This is the harmful effect that a low-supply efficiency will have on your forces. Any force that is not receiving
enough supplies will begin to suffer attrition, which reduces both your troops’ strength and their organisation.
In “real life” this didn’t necessarily mean that soldiers perished, but lack of supply led to all sorts of ailments
that resulted in soldiers becoming too ill to fight or in equipment breaking down due to being used in condi­tions that exceeded their design specifications. The degree of attrition is determined by the effective supply
efficiency in a province as modified by the terrain, weather conditions and climate. All of these will take their
toll on your forces and can deal just as crippling a blow as any direct enemy attack can achieve. As a result, you
should do everything you possibly can to avoid placing your troops in a situation where attrition levels will be
high, unless there is a very large strategic advantage for doing so that cannot be achieved in any other way.

Supply Chains

Now that we’ve looked at transport capacity and supply efficiency, we can address the overriding issue
supplying your forces. In “real life”, the logistics involved in supply chain management are very complex and
time-consuming, and more importantly, it’s not one of the more interesting or entertaining roles for a player to
assume. Hearts of Iron II abstracts this using the previously described transport capacity and supply efficiency
systems. What remains - and what you must pay close attention to - is the issue of supply chains. For the sake
of clarity and convenience I’ll be using the term “supplies” in this section to refer to both the supplies and the
fuel (oil) that your divisions require to operate. You will need to concern yourself with both.

Transport Capacity at a Glance

Shipping 1 fuel uses 1 TC
Shipping 1 supplies uses 1 TC
Maintaining control of an occupied province uses 1 TC
Each unit held in the force pool uses 2 TC
Each division being strategically redeployed uses 2 TC

A supply chain is the actual path that your supplies will take in order to reach your troops. It must start at a
depot that has the necessary supplies and then follow an unbroken chain of adjacent provinces until it reaches
your divisions. If that chain is broken, the supplies will cease to reach your troops and they will begin to suffer
rather nasty attrition effects that will reduce their strength and organisation. A supply chain must be traceable
through friendly provinces - ones that you control, that your allies control, or provinces belonging to nations
with whom you have a treaty of military access. You cannot trace a path through enemy provinces, or provinces
belonging to neutral nations, unless, as just mentioned, you have a military access treaty with them. You cannot
trace supply directly across water but you can create a new depot in a coastal province that you control and
then use convoys to ship supplies to that depot from somewhere else, usually your capital.

You can also be supplied by one of your allies, provided that they have the necessary supplies in their depot.
Of course, this can put undue strain on their supply capabilities, eventually causing problems if there is a large
concentration of allied troops in an area. Keep in mind that the reverse is true as well, that your allies may
draw supply from you if they need to and they won’t ask you before they do, making this a good reason to
maintain extra supplies in a depot.

Supply chains are automatically created for you if your divisions can trace an unbroken path of provinces
to a friendly depot that has the necessary supplies. It is assumed that the necessary supplies can reach the
provincial border without much trouble, so the ESE calculation is only applied to the province that your divi­sions are currently occupying, and not to each province in the chain. This abstraction and somewhat incorrect
assumption is necessary to prevent undue CPU load that would slow the game to a crawl, and to avoid forcing
you to micromanage the exact route that every single one of your supply chains uses when there are multiple
possible paths. When the supply chain is created, it will always use the closest available source of supply first.
This could easily be an ally’s depot rather than your own, as long as it has the necessary supplies. If that depot
lacks the necessary supplies, the next closest depot will be used, and so on. As long as you or your allies have
a depot somewhere that has the supplies and can be linked, you will remain in supply.

While the Supply Mapmode will display all provinces that currently could receive supplies, this doesn’t neces-
sarily mean that the supplies are actually in place. If you become cut off from your capital or if you lack the
supplies and fuel in either your national stockpile or that of your ally, you will be in very deep trouble. The
best way to check a division’s current supply status is to select the field command and look at its status on the

HEARTS OF IRON DOOMSDAY

display. A small dot appears in the status area to indicate that the field command is in supply, and the source
of that supply is listed immediately below this. If it isn’t in supply, this will be indicated as well.

Overseas Supply

While supply chains are established automatically, overseas supply also requires that a flow of goods move
from your capital, where supplies are manufactured and collected, to whichever depot is acting as the supply
source for your forces. You can have this done automatically for you by selecting the Auto-Create/Destroy
Supply Convoys option in the Convoy Management interface, which is accessed via the Production Folder.
You may prefer to manage this yourself, using the same interface, to build up extra supplies. Don’t forget to
correctly identify the materials that this convoy should transport, and if that depot is also a collection point for
oil from local provinces, you will also need to ensure that any convoys that are shipping goods back to your
capital don’t end up taking oil away from this location.

Air Supply

In an extreme situation, your field command may become completely cut off from supply. In such a case, it
is possible to use transport aircraft to ship supplies to your encircled forces but this is extremely expensive and
very inefficient, not to mention that enemy fighters will do their best to blow your transports out of the skies.
Using air supply will create a new depot in the province that your transports are shipping to - a depot that could
subsequently be captured by the enemy, and should be considered as only a short-term emergency measure.
Details of how to assign this mission are given in the Air Combat section.

Reinforcement

Any unit that is in supply and that has sustained casualties may be reinforced back up to full strength by
allocating some of your national IC to reinforcement. The details are then automatically handled for you by
deducting the necessary manpower and IC and gradually replenishing your divisions. This can take some time,
and the newly added strength will reduce your unit’s experience a bit since these reinforcements are new
recruits and not battle-hardened veterans.

If you click the prioritise button for a field command, it will be given top priority for reinforcement but it will
still take a bit of time for the losses to be replenished. If you click the reinforcement button, you can prevent
all divisions within a field command from being reinforced.

Upgrading

New technologies will be made available to your forces as soon as the research has been completed. To
upgrade your units, you must allocate some of your national IC to this purpose, and the units must be in
supply to receive the advances. This does not dilute their experience but can take a little while to achieve. As
with reinforcements, units can be given precedence by clicking the prioritise button in the field command
information panel; conversely, they can be denied the new technology by clicking the upgrades button. Units
in the force pool are not upgraded until they have been deployed, and any units that weren’t in supply at the
time that the new technology became available will be upgraded once they are back in supply.

Disband

To disband any division, go to the division details information panel and click the disband button. This will
return some manpower to your national manpower pool if there’s room, but their experience is lost, as is the
original investment in IC that you made to produce the division. You will probably not need to do this very
often unless you are seeking to reduce your overall national force strength to conserve transport capacity, or
minimise the amount you must spend on manufacturing supplies. Remember that divisions that consume oil
do not do so unless they are moving or in combat, so oil stockpiles may be maintained by simply keeping

2



HEARTS OF IRON DOOMSDAY

those forces stationary.

Basic Army Movement

As long as no combat is involved, you can order field commands to move from one province to another
with relative ease. Select the force that you wish to move and right-click on the province to which you would
like it to move. A movement arrow will appear and the force will immediately begin to move to that province.
The colour of the arrow will always be blue if you’re moving to a friendly province, or red if you’re advancing
into enemy territory. The target province does not need to be adjacent to the province currently occupied by
the traveling unit, though it must be possible for the field command to move to the new province without
crossing water or entering a neutral country’s territory. You may only move into one of your provinces, your
allies’ provinces, a province belonging to a neutral country with which you have a treaty of military access, or
into enemy territory.

The length of time it will take to move into an adjacent province depends on the terrain and weather condi­tions of the province to which it is moving (not the province that it currently occupies), the movement rate
of the slowest division in that command, and the ESE of that province. The ETA will be displayed in the Field
Command Details display, just below the mission box and the mission will be updated to indicate that the
force is moving. If any of these movement conditions change, the ETA will be revised to reflect this. As the
movement occurs, the blue movement arrow will darken in order to give a graphic indication of its progress. If
you want to stop the unit from moving while canceling the order, select it and right-click in whatever province
it is currently located.

If you hold down the Ctrl key when you right-click on the “target” province, the Orders Interface will appear,
which will be used extensively for combat. For simple movement, you should use the “attack” mission since an
attack on a friendly province is automatically recognised as an order to move there. You will see the date and
time that the force is expected to arrive if the conditions do not change and may adjust this to any later time
or date if you wish, representing a useful means of synchronising the arrival of multiple units. The unit will not
begin to move until you click the OK button to issue the order.

When you are moving to a more distant location, the path that is chosen automatically for your force may
not be the one you wish it to use. This might be due to the terrain it must traverse, or you might wish to keep
it away from an enemy’s border to keep its presence a secret, or you may even wish to avoid a location that
is subject to frequent enemy bombardment. Whatever the reason, you may easily select the path that a force
will use by holding down the Shift key and then right-clicking on each province you wish it to use. You may
combine the use of the Shift and Ctrl keys to further refine the orders.

Transporting Troops on Ships

To move land forces across water, you must transport them using your naval transport vessels. Each naval
transport has sufficient carrying capacity to handle one full division and, if necessary, an attached brigade. To
be able to transport a field command, you must either have a sufficient number of transports or you must
reorganise your force until it is the appropriate size. Once you have done this, there are two ways to load a field
command onto a transport vessel. If the force is in a port that also contains the transports you intend them to
use, you can select the force and click the load on transports button. The force will be immediately loaded
and you can then issue orders to your transport as to where to take them. The other option for loading troops
is used when the transports are in an adjacent sea area, usually because your troops are not in a port. In this
instance, select your force and then right-click on your transports to issue an order for them to begin loading.
This process will take some time and leaves both your field command and your transports open to enemy
attack. Should this happen, the process will be halted until the enemy has been repelled, at which point the
process will resume. If your navy fails to successfully defend against the attack, the entire process is cancelled

HEARTS OF IRON DOOMSDAY

but fortunately, no portion of your field command will be damaged. Once loading has been completed, you
can select the transports and issue them their orders.

Unloading of transports will occur automatically if their destination is a port. If you wish, you may unload
your force from a transport when it is in the sea zone adjacent to a desired friendly province. To do this, select
the transports and then click unload button. This will automatically select the field command that you are
transporting, leaving you free to designate the province you want them to unload into by right-clicking. Again,
this will take some time to complete and is subject to enemy interference. Unlike the loading process, failure
here can be catastrophic if a transport is sunk since your troops will go down with the ship. As you will have
gathered from the comments above, it is much faster and safer to load and unload your troops in a friendly
port if at all possible, and to reserve “adjacency” loading and unloading only for emergencies.

Unloading troops into an adjacent province that is in enemy hands can be done by using the adjacent sea
zone unloading method or by using the naval “amphibious assault” mission. To launch such an attack, the
province must have a beach.

Transporting Paratroopers

Unlike naval transports, which can carry any type of land division, air transports are only able to carry airborne
infantry. Each air transport can carry one division of paratroopers and the method for loading and unloading is
more or less the same as it is for naval vessels. The only difference is that you must select the target province
for the paratroopers to jump into, or select an airbase for the transports to land at to deliver their troops.

Strategic Redeployment

For basic redeployment of land forces to more distant locations, it is usually easiest to issue them a strategic
redeployment order instead of physically moving them there. While this usually takes slightly longer than
marching, there are several advantages to this technique. The first is purely a matter of convenience since the
order is very simple to issue. A less obvious one is that during the course of their redeployment, they are not
subject to attrition losses or enemy attack, both of which can take their toll. Strategic redeployment will use 2
TC of your national transport capacity for each division being redeployed this way.

Issuing a strategic redeployment order is remarkably easy to do. Simply select the field command that you
wish to redeploy, hold down the Ctrl key on your keyboard and right-click on the province where you want the
force to redeploy. It must be a province that you control not one that is controlled by an ally, and there must
be a land link through friendly territory between its current and intended locations. The unit must also be in
supply. Because you are using the Ctrl and right-click combination, the order interface will be displayed, from
which you need only select the strategic redeployment option. In this instance, the exact arrival date will be
displayed though you can’t adjust it, leaving you to then click the OK button to issue the order, or Cancel if
you change your mind.

The field command will be immediately removed from the map and placed in the force pool with a nota­tion as to where it is being redeployed and the date that it will arrive. During this time, you cannot change or
abort these orders. If their destination province falls into enemy hands before they arrive, they will be placed
in the first available friendly territory that is along the route that they were taking to the originally intended
province.

Basic Land Combat

Overview

Now that we’ve looked at the details of your forces, deployment, basic movement and supply, we can finally
begin to discuss combat. To avoid throwing too many options and variations at you all at once, we’ll start by





HEARTS OF IRON DOOMSDAY

looking at what happens when one of your land forces engages an enemy’s land force - a simple one-on-one
engagement between two opposing field commands. This will introduce the basic rules that make up the core
of Hearts of Iron II’s combat system. In subsequent sections, we’ll look at more complex situations where
multiple forces are participating, and where air forces and navies get involved.

In Hearts of Iron II, combat represents the struggle for control of large provincial areas and should be thought
of as a series of engagements, rather than a single battle between two large forces. Battles can often last for
many hours, days, or even weeks, depending on the size of the forces involved and how well-prepared the
enemy is to defend the province. It will continue in a series of combat rounds until one side is either victori­ous or is ordered to disengage. If the defender is victorious or the aggressor breaks off the attack, things will
remain status quo. If the defender chooses to flee or has been forced into full retreat, the attacker will begin
to move into the province to clean up the last pockets of resistance and begin the occupation of the newly­conquered province.

Entrenchment - Digging In

Before we look at initiating combat and how it’s resolved, we need to quickly touch on two subjects: entrench­ment and provincial defences. Entrenchment is an indication of how well-prepared the defending force is to
repel an attack; it will be available after you have researched the appropriate technology to enable it. You can
check the status of your land forces by selecting the field command and looking for a small shovel icon in the
status area. A shovel indicates that your force is entrenched or “dug in” to at least some degree. If you hover
your mouse over the shovel, a tooltip will appear to show your dug-in status. The higher the number, the better
prepared they are and the greater their defensive bonus will be. A force that remains stationary in a province
for a while will become increasingly dug-in, raising their bonus until it reaches its maximum possible value. The
bonus is immediately lost if it begins to move.

While there is no way to check an enemy’s entrenched status, you could make an educated guess if you
know roughly how long they have been there. A well-entrenched enemy will be considerably harder to defeat.
Attackers do not receive a dug-in bonus, obviously, since they are moving.

Province Defensive Structures

While entrenchment can help a defender repel an attack, it is a poor substitute for a network of fixed de­fensive structures that are designed specifically for this purpose. A force that is in a province containing land
fortifications will gain an edge in combat that is proportional to the size of the fortification, in addition to any
entrenchment bonus they receive. A division that is entrenched, in supply, at full strength, and well-organised
can be an almost unbeatable opponent so it is best to find a way of reducing at least a few of those factors
before launching an assault against them.

Land fortifications only aid a defender against an attack from another province, not against one that comes
from the sea. Coastal fortifications perform the reverse function, repelling sea invasions but having no effect
against an army that is advancing from an adjacent province. Neither of these defences have any impact
unless there are forces present to man them, and neither of them are used against any paratroopers who
attack you, although paratroopers are subject to a separate combat penalty. Anti-aircraft and radar installations
require no one to man them but have no effect whatsoever on advancing land forces, though they will help
you against any supporting enemy aircraft.

HEARTS OF IRON DOOMSDAY

Initiating Basic Land Combat

All land battles in HoI2 involve two sides - an attacker and a defender.
Combat is initiated whenever a field command is ordered to move into an
adjacent province that contains an enemy field command. The defender is
always the force that occupies the province and is attempting to hold it;
the attacker is always the force that is attempting to capture the province.
When you order a field command to move into an undefended enemy­controlled province, there will be no combat and a movement arrow will
appear. The arrow will be red to indicate that the command is moving to
occupy an enemy province.

Whenever the target province is defended, right-clicking on a it will auto­matically display the Orders interface, so there is no need to hold down
the Ctrl key as you do so, though it isn’t a bad habit to use the Ctrl key

field command is able to perform, and the attack option will be pre-selected. The interface will also indicate
the date and time that the attack is to begin, and will typically indicate the current date and time. This won’t
always be the case because the game tracks your recent orders, and if it seems appropriate, the default time
will be set to coincide with the others. It might take a little getting used to but this feature is an incredible time­saver, and the default attack time can easily be overridden by adjusting the values using the “+” and “-” but­tons. To simply go ahead and launch the attack, click the OK button. The Orders interface will

information panel. Depending on your current message settings, you may get a pop-up message box to inform
you that battle has been joined. The easiest way to view battle locations is to click on the Active Combats Hot
Button which will display the combat quick view (see below) for any battle or provincial occupation that is
currently underway.

close and the field command’s orders panel will be updated to reflect its
new mission. If the attack is to begin immediately, the red movement ar­row will also appear on the map if the unit is still selected. If you have set
a delay on the timing, the arrow will not appear until the attack actually
begins.

As soon as the combat begins, a variety of game interfaces will also be
updated to reflect the fact that a battle is taking place. In any interface
where the field command is listed (i.e. if you click on the Land Forces Hot
Button), you will see a small red battle symbol at the right edge of the
display. If you click the Province Hot Button, you will see the same symbol

Timing Your Attack

It is usually best to launch an attack that is timed to begin at daybreak or at least during daylight hours, since
most forces don’t fight very well at night. This is easily done on the Orders Interface where you can adjust the
exact date and time that you would like the attack to begin. The time displayed in the Orders Interface is always
GMT, not local time, and a small symbol in the interface will indicate whether this will be a daytime or night
time attack. In more advanced combats, you will frequently use this interface to time the various components
of your attack (i.e. to conduct preliminary aerial bombardment to soften up the enemy before your land forces
begin to advance) or to gradually escalate the scale of the conflict.

Basic Combat Resolution

As soon as battle is initiated, you will notice that the Field Command details in the information panel changes
to display a “combat quick view” at the top in place of the usual province details. The mission box will display
the unit’s current orders, such as “Attack” if it is the aggressor, and below this will be a brief graphical summary
of the current status of the battle with the province name and battle icon in the center. On either side, you’ll
see the portraits of the opposing commanding officers, their current strength and organisation, the number of
divisions involved on both sides, and their nationalities. The attacker will always be listed at the left side of the
summary and the defender at the right. Below this is a bar that stretches from left to right across the bottom of
the battle summary, indicating which side currently seems to hold the advantage. If this is mostly red, the at­tacker seems likely to win. If it’s green, the defender would seem to be prevailing. This status is not a guarantee
of victory, however, since many things may happen during the course of a battle that could tip the balance.

This same combat quick view also appears in the list that is displayed when you click on the Active Combats
Hot Button; remember that you can also filter this list to display only a particular type of battle. If you click
anywhere on the combat quick view display on either interface, the information panel will change to display
the combat details view. As is the case with the quick view, the attacker is always listed on the left side of the
display and the defender on the right.

The name of the province that the two forces are vying for is listed at the
top. The portrait of each commander will be displayed below his national
flag, along with two numbers: the number of divisions that he currently
commands, and the maximum number of divisions that he is able to com­mand. If the first number is smaller than the second, the commander’s
capabilities are not being exceeded; if the first number is greater, he is
commanding too many divisions and is deemed overstacked. The severe
penalties received for overstacking are detailed later in this section.

There is a small “event box” just below this that stretches between the
two leaders’ portraits. It will normally be empty, though there are special
combat events that may occur during the course of battle. These are far
more likely to be in your favour if you have a high-ranking leader who
commands an HQ division somewhere in the vicinity. If an event occurs,
it will be listed here. Details on combat events may be found a little later
in this section.

In the next section of the information panel, you’ll see a series of symbols
that will change as the battle progresses as well as the same red-green
battle status bar that appears in the quick view. The symbols that appear
in this area will indicate various special combat conditions that are af-

river crossing, overstacking, weather conditions and more. Each of these will have an effect on how combat
is resolved and are shown as quick visual “clues” as to what factors might be influencing the battle. Details
concerning the exact bonus or penalty will vary somewhat depending on a unit’s type and technology, so the
precise values of the modifiers are not displayed here, but are incorporated into the next part of the informa­tion screen.

fecting the battle, conditions such as entrenchment, night time combat,

HEARTS OF IRON DOOMSDAY

The balance of the information panel displays a complete scrollable list
of the units involved on both sides of the conflict as well as a graphic
representation of each one’s remaining strength and organisation. An ex­panding tooltip is available for each division that contains precise details
about the various bonuses and penalties that it is receiving to its combat
values, along with a calculated total indicating its current attack and de-

values shown in the tooltip include all of the various modifiers that are listed below them. These will frequently
change, as they are updated on an hourly basis as the combat progresses.

A combat can last for as little as a few hours or possibly for as long as a few weeks, though the majority will
probably be waged for a matter of days. Battles are subdivided into “rounds”, with each round lasting one
hour. During each round, a variety of things will occur:

• There is a chance that a combat event may occur at the beginning of the round, representing a special

advantage that one side has managed to achieve over the other. The likelihood of one happening that
favours your side is determined by the land doctrines that you have researched, which may increase the
odds of a specific event occurring. This is also considerably more likely if you have an active HQ division
in a province that is adjacent to the battle or involved in the battle; to be active, it must be commanded by
a general or by a field marshal. Several of the officer traits will also increase the chance of a specific type of
combat event being fired. If an event occurs, its effects will remain active for eight hours, represented over
the next 8 rounds, and no other combat event can occur until it has expired.

• The attackers will inflict some damage to whatever provincial assets exist in the province. If the defenders

have a land fortification, or a coastal fortification in the case of an amphibious assault, it will sustain some
direct, intentional damage. The amount of damage is tripled for divisions with an engineer brigade attached
to them. There will also be some collateral damage to infrastructure, factories, and other structures that will
reduce their operational conditions until the damage has been repaired.

• The combatants will exchange fire, with each side likely sustaining some level of casualties and probably

experiencing a slight reduction in organisation and morale.

• Both combatants will also draw a measure of supplies and oil to sustain them for the next combat round.

This will be at a somewhat higher rate than their normal hourly consumption, and if there is a lack of either,
their combat organisation and morale will begin to drop quite sharply. Running out of supplies or fuel is
a sure way to lose a combat.

• At the end of each round, the operational status of each division is checked to see whether it is able to con-

tinue fighting. A division that has sustained enough casualties to reduce its operational strength to zero will
be eliminated. More often, though, a division will reach a point where its organisation has been reduced to
a level where it cannot continue to fight (below 5%) and will begin to withdraw. It may still be fired upon
and will try to defend itself but it will no longer attempt to inflict casualties on its enemy.

This cycle will repeat each hour that the combat continues until either one side has been completely elimi­nated, which is quite rare unless the battle is very lopsided, or until at least 50% of a side’s divisions are in the
process of withdrawing from battle. However, you may elect to disengage from combat at any time if you feel
that your chances of winning are slim and you would like to preserve as much of your force as possible. If you
are the attacker, you can do this by selecting the field command and right-clicking in the province that they
currently occupy. In the case of a defender, you can select the force and then right-click anywhere, since there
are special rules that govern retreat from a province.

HEARTS OF IRON DOOMSDAY

Exchanging Fire

In the above description, I simply indicated that the two sides “exchange fire” each hour. This is actually a
very complex process whose precise mechanics are embedded in the game engine, but you need to have at
least some idea of how it works in order to be able to make an informed decision about whether to initiate
a combat and what forces might be useful for you to build, deploy, and order into the battle. Here’s roughly
what happens…

The firing phase of the combat is subdivided into a number of “shots”, such as shot 1, shot 2, shot 3, shot 4,
and so on until all possible shots have been fired. For each of those shooting rounds, each division on both
sides will randomly select an enemy division to fire at and then will target either its hard or its soft component.
The likelihood of it picking a soft target is equal to the enemy division’s softness value, so if your division is
shooting at an enemy division with a softness of 70%, there’s a 70% chance that it will target the soft compo­nent and a 30% chance it will target the hard component.

Your division then checks whether it is “allowed” to shoot by checking its hard or soft attack value. Whether
a division is allowed to shoot depends on what shot number it is and on the attack value it has against the
target type it has selected. Example: If it chooses a hard target and has a hard attack value of 5, it will be
allowed to shoot if it is presently shot #5 or earlier. If it’s shot #6 or later, it is not permitted to shoot.
That doesn’t necessarily mean that its attack is over for this round of combat, because if it happens to have a
soft attack value that is higher, it might still select a soft target for a later shot at which point it will be able to
shoot. Example: If that a division has a soft attack value of 12, it will be allowed to shoot if it happens to

select a soft target any time up to round #12.

If a division will shoot if it is allowed to do so, but the target division will also have a chance to avoid being
hit. Whether the target is able to avoid the shot is determined by either its defensiveness value or its toughness
value, depending on whether it is the defender or the attacker in the overall combat. If it is defending a prov­ince, it uses its defensiveness value; if it is a division on the attacking side, it will use its toughness value. This
value is the number of times that it may attempt to avoid being hit during each full combat round. Example:

An attacking division that has a toughness value of 10 may attempt to avoid being hit on the first ten
times that it is targeted by defending divisions during each combat round. If it is targeted by 5 enemy
divisions in the first shot, 4 divisions in the second shot and 4 divisions in the third shot, it can only at­tempt to avoid 10 of those 12 shots. It would not be able to avoid any subsequent shots that were fired
at it until the start of the next combat round. In normal combat situations, a division will be able to avoid

a majority of the shots directed towards it, so it is unlikely to sustain significant damage unless its avoidance
opportunities have been exhausted while its enemy still has additional shots remaining.

A shot that successfully hits its target will inflict damage on the target division. The extent of that damage de­pends on the type of the division that fired the shot and on the type of target it selected. Foot soldiers (infantry,
marines, militia, etc.), cavalry and motorised infantry will generally inflict a bit more damage to a soft target
than a mechanised infantry or armoured division will achieve, though the latter are more effective against hard
targets than their “weaker” brothers in arms. There is also a strength component to the damage, with the per­centage of strength that the shooting division has lost being applied to the amount of damage it can inflict.

But wait…there’s one more twist! You might have been wondering what the tooltip values of “attack effective­ness” and “defence effectiveness” mean and then guessed - incorrectly as it turns out - that these values might
represent your chances of hitting a target or avoiding getting hit. They don’t. The attack effectiveness modifies
your division’s soft and hard attack values by that percentage, while the defence effectiveness is applied to your
defensiveness or toughness value, depending on whether you are the attacker or defender. This means that
they will increase or decrease the number of shots that each division may fire in each round, and the number
of shots that they might be able to avoid when they are targeted. Attack and defence values must be whole

HEARTS OF IRON DOOMSDAY

numbers because you can’t partially shoot or partially defend, so any fractions that result from the effectiveness
modifiers are ignored. That means that a soft attack value of 5.99999 would restrict a division to firing at a soft
target only during the first 5 shots of the round, and that a defensiveness of 5.99999 would allow you to try
avoiding a shot only five times during that round.

All of the above occurs every combat round until the battle is over, and is thus repeated on an hourly basis,
with some likelihood to change to at least some degree. What will therefore tend to have the greatest impact
on a battle is the quality of the forces that you employ and the modifiers that come into play during the course
of the engagement.

Modifiers That Affect Battle

There are a great many factors that will play a role in the outcome of a battle. Almost all of these are modifiers
that are applied to the attack and defence effectiveness values, thus altering the number of possible shots you
can fire or avoid each round. Some of these, like terrain modifiers, will remain constant throughout the course
of a battle while others may have shorter durations, such as night time penalties, or changing weather effects.
It isn’t practical to list them all here, and many have already been mentioned earlier in the manual, so I will
only highlight a few of the more significant ones.

Leadership will have a very large impact on the effectiveness of your forces. Some officers have traits that
will give significant bonuses that can offset other penalties or give certain types of divisions an advantage, and
an officer with high levels of skill can also give a substantial boost to these values. The biggest issue you’ll en­counter, though, will be the nearly catastrophic penalties incurred if your leader is overstacked. As you’ll recall,
each leader has a rank and this rank will determine how many divisions he can command without penalty.
This number is doubled when an officer is within a one-province radius of an active HQ division. If he exceeds
his limit, all of the divisions under his command will forfeit any bonuses that his trait or skills would normally
have given them. Worse still, the “excess” divisions will receive a 75% penalty to both their attack and defence
effectiveness values. This will make them very easy for the enemy to hit and also means that they aren’t likely
to be able to shoot very many times during a round. When we move on to look at more complex combats, we
will discuss the effects of having multiple officers participating on one side of a battle.

Beyond the possible weather and terrain modifiers - which, as detailed earlier, can occasionally be nasty

- there is a large penalty applied to night time attacks and, to a somewhat lesser degree, defence. Making an
amphibious landing, crossing a river or parachuting out of the sky will also limit your effectiveness, although
the latter has the benefit of avoiding the very substantial penalties incurred for attacking a fortification.

National dissent will also impose a noticeable penalty on your forces if you allow it to rise. At low levels, it
may only hamper your forces slightly, but the higher it rises, the more painful its effects will become. If you
expect to be involved in many combats, you would be very well advised to deal with your domestic situation
as rapidly as possible…or face the consequences.

There are a host of modifiers supplied by various technological advances, particularly by combat doctrines,
as well as by such things as your current ESE, the experience of your forces, and so on. While it might seem
that most large modifiers favour the defender, and that is actually the case for simple battles such as the ones
we’re considering here, this can easily be offset in more complex combats by an envelopment factor, which
is applied when the attack is launched across multiple provincial borders. It will take some time to become
familiar with all of the possible situations and resulting modifiers, so my advice to you is to play the game,
try various alternatives, and learn from experience. Pay close attention to the tooltip details during combat as
you’re learning, and you may want to pause periodically to spend some time reviewing them for each division
if a combat isn’t going quite the way that you think it should.
