The division is the basic unit depicted on the map during gameplay. The composition of each division is specified by its division template. Division templates may be created and modified by spending 陆军经验army experience.

师编制

Each country starts with one or more division templates that may be used to order recruiting and deployment of new land units. These templates may be modified by the player, or new templates created by either using the Duplicate button to make a duplicate of a template, giving it a name different from existing templates, and then making modifications to a template as described below, or by selecting the name and pressing "Create Empty". Land experience is not charged until the changes are saved using the Save button on which the total cost is also shown, so players can experiment and analyze the results of changes before making a decision. When a template is changed, all divisions that are based on that template immediately place orders for additional needed manpower and equipment and return any manpower or equipment that is now surplus to the national stockpile. It is wise to have any needed manpower and equipment ready in the national stockpile before changing the template of a division that may be expected to face combat in the near future. It may be prudent to upgrade units one at a time.

Divisions can not be divided into smaller game units, but since Patch 1.5 it is possible to merge understrength divisions of the same template in the Army window using the Consolidation button if the selected divisions are independent of any army command. Such consolidation can be extremely useful for a country low on manpower or equipment that needs to field adequately sized divisions.

The template a division uses can be changed at any time by selecting the unit helmet, tank or other unit symbol icon in the Unit Details screen when that division's template is open and choosing any of the templates available there.

Each division consists of up to five combat regiments and five support companies. In turn, each combat regiment is composed of up to five battalions. It costs 5 XP to add a battalion to a division; regardless if it is the same or new regiment. Adding a battalion of a different unit type (infantry, mobile, or armored) adds a penalty of 20 XP per additional unit type.

A division may have any number of the same unit type for battalions, but only one of each unit type for support companies.

A division template may be specified as reserve, regular, or elite. Elite divisions will be prioritized for better equipment, followed by regular divisions and finally reserves.

Each division template can receive specific types of equipment if multiple types are available. An example would be elite divisions only using the latest weapons and reserve divisions using the oldest.

Combat Battalions

Each combat regiment in a division consists entirely of a mix of battalions within a single battalion type. The three battalion types are:

  • Infantry battalions: Infantry, special forces, line (towed) artillery/anti-air/anti-tank
  • Mobile battalions: Cavalry, motorized infantry, mechanized infantry, motorized rocket artillery, motorized artillery/anti-air/anti-tank, armored cars
  • Armored battalion: Tanks, tank destroyers, self-propelled artillery/anti-air, amphibious tanks

Increasing the number of battalions in a division modifies the stats of the division: for example new combat battalions increase the HP and combat width of the division, and typically increase at least the different attack and defense statistics. Note that the division's organization is the average of the organization of the included battalions, thus it is possible that the division's (average) organization actually drops when adding new battalions. See § Sizing for more discussion on this.

For the armor, piercing and hardness stats there is a different calculation:

  • Armor: 30% * (Highest Armor of a Battalion) + 70% * (Average Armor for All Battalions and Companies) = Armor of the Division
  • Example: If there are 3 Batallions, 2 Infantry (1936), and 1 Light Tank (1934), then the calculation would look like this:
30% * [Highest Armor] + 70% * [Average]
30% * [10.0] + 70% * [3.33 ((0 + 0 + 10) / 3)]
3 + 2.31
= 5.31
  • Piercing: 40% * (Highest Piercing of a Battalion or Support Company) + 60% * (Average Piercing for All Battalions and Companies) = Piercing of the Division
  • Hardness: Average of Hardness of Line Battalions = Hardness of the Division
  • Example: If there are 4 Batallions, 2 Infantry (1936) and 2 Light Tanks (1934), then the calculations would look like this:
Average of Hardness of Line Battalions = Hardness of the Division
(80 + 80 + 0 + 0) / 4
160 / 4
= 40

Support Companies

A division may have up to five different support companies. These are referred to in doctrines and elsewhere in the game as 'integrated support', distinguished from 'dispersed support' which is an Artillery, Anti-Air or Anti-Tank type regiment included in a combat regiment column. Support company options are:

  • Support Artillery: Gives a smaller bonus to soft attack than a line regiment's artillery battalion because it has fewer guns. It does not slow the division† or affect paradrops.
  • Support Anti-Air: Gives a smaller bonus to air attack than a line regiment's anti-air battalion because it has fewer guns. It does not slow the division† or affect paradrops.
  • Support Anti-Tank: Gives a smaller bonus to hard attack and piercing than a line regiment's anti-tank battalion because it has fewer guns. It does not slow the division† or affect paradrops.
  • Support Rocket Artillery: Similar to regular support artillery but it also gives a bonus to the division's breakthrough stat, used to avoid enemy attacks when attacking.
  • Engineer Company: Increases the Entrenchment stat of the division and helps in attacking forts and river crossings.
  • Cavalry Recon Company: Increases speed in difficult terrain and the division's Reconnaissance stat, making it easier to counter enemy combat tactics in battle.
  • Motorized Recon Company: Increases speed in difficult terrain and the division's Reconnaissance stat, making it easier to counter enemy combat tactics in battle.
  • Armored Car Recon Company: Increases speed in difficult terrain and the division's Reconnaissance stat, making it easier to counter enemy combat tactics in battle.
  • Light Tank Recon Company: Increases speed in difficult terrain and the division's Reconnaissance stat, making it easier to counter enemy combat tactics in battle.
  • Military Police: Gives a bonus to the Suppression stat of its division's line battalions, helping to reduce the effects of partisans. Military Police with 2-6 minimally equipped and trained Cavalry battalions makes an efficient and effective rear-area security division.
  • Maintenance Company: Adds an equipment reliability bonus to the division, reducing equipment losses from training and combat. Advised for combat units using expensive equipment (like tanks).
  • Field Hospital: Increases Trickleback stat (returns percentage of lost manpower to the pool) and reduces experience loss from taking casualties. Advised for front-line combat divisions.
  • Logistics Company: Reduces the supply usage of the entire division. This is valuable in areas of low supply and for avoiding the need to disperse for supply reasons.
  • Signal Company: Increases the Initiative stat of the division, speeding up planning and increasing the chance of reinforcement in battle from reserves.

† Note that support companies do not affect a division's speed and do not affect combat width as they are forces that remain behind the fighting front while the "front line" combat battalions engage. Therefore a towed antitank support company does not affect the 12 kph speed of a fast division but adding a towed antitank combat battalion to the regiment lines would slow that same division to the towed anti-tank's base speed of 4 KPH. So support Artillery, Anti-Air or Anti-Tank support units can add valuable capabilities to fast divisions. An infantry division marching at 4 kph is well-matched by combat battalions marching at 4 kph as well. Additional bonuses and effects of adding a support company to overall division stats can be seen in the tooltip in the division designer. Even though these companies may historically have been much larger than company size, they are referred to as support companies to distinguish them from the battalions in line regiments.

Armored Templates

Some countries already have some tank equipment researched in 1936, and these get an armored template at the start of the game. This is usually a historic template that matches the order of battle of one or more of their starting divisions. For example, Italy ("Divisione Celere" template) and the Soviet Union ("Mekhanizirovaniy Korpus" template) are both in this situation. These templates allow you to create new armored divisions with light tanks. If you have any army experience, then you can change the historic template.

A few countries have some tank equipment already researched when the game starts, but don't actually start with any historical armoured divisions. For example, Commonwealth countries like Canada who get tank equipment researched in 1936 (shared with them by UK), though they have no armored divisions then. These countries get an armoured template at the start of the game (called "Armored-Division"), so they can create armored divisions later.

All other countries get a free template (called "Armored-Division") when you research your first tank equipment.

The free "Armored-Division" template, and those templates which some countries start with, are always light tank templates. You have to use some army experience to modify these, or modify a duplicate, for use with Medium or Heavy Tanks. As soon as you complete the research, the Division Designer will allow you to replace the Light Tank Battalions with Medium or Heavy. This costs 5 XP for each battalion.

Hardness

Hardness Bar.jpg

The Division Designer has a bar just below the stats, which shows the Hardness of the divisions created with the template.

The Hardness represents how much of your division is made up of armored or at least protected vehicles. The free "Armored-Division" template has only 35% hardness, even though it has two light tank and two cavalry battalions. You can increase the hardness by adding more tank battalions, or replacing light with medium, or medium with heavy. Or by replacing "soft" battalions (infantry or cavalry) with motorized or mechanized battalions.

For example, replacing the two light tank battalions in the default "Armored-Division" template with medium tanks, and the two cavalry with mechanized, changes the hardness from 35% to 70%. Divisions with high hardness will suffer few hits in combat from divisions with low hard attack values - such as infantry with 1936 equipment and no anti-tank equipment.

Sizing

The values of land units combine in different ways in divisions, and these values have special implications for deciding whether one should "scale up" a division template, e.g. doubling up the battlions to go from a 20 combat width to a whopping 40. Any modifications must be view in the context of the current land warfare damage system.

As mentioned previously, soft/hard attack and defense/breakthrough are additive; doubling the width of the template doubles these values. In the current system, only 10% of the attacks are considered for damage if they are covered by the other unit's defense, but 40% is considered when the attack points have exhausted the defense points. In other words, an attack point not held back by the enemy's defense is four times as good as an attack point that is held back. Although units do drain the enemy units' defense together, having a larger division in this case still allows you to more effectively drain the enemy units' defense, compared to having two smaller divisions of the same smaller size, by removing a random element and allowing the draining to be concentrated.

On the other hand, doubling the division size does not make the divisions two times more resistant to actual damage, since the organization does not scale up. Damage is two times more frequently dealt to organization instead of HP (which is additive), and defense is often easy to stack up for land units anyways. Having small divisions is additionally more versatile due to the sheer number of divisions, allowing one to run encirclements and cover up extending lines when needed; however this also takes up commanding official capabilities. Small divisions also allow more support weaponry companies to be used, many of which are more economical in their stats contribution per equipment than line companies; on the other hand, they increase the cost of non-weapon support companies, since more of them are needed to achieve the same percentage bonus.

Division unit type

The overall division unit type is indicated by its default division icon. The division unit type is determined by multiplying an internal priority score by the number of units of each type, and taking the unit with the highest score. If there are multiple units with the same weighted priority, the first (top, left) unit is used to determine the type.

Once the exemplar unit is established, the internal types of the unit as shown below determine whether military high command bonuses or commander traits apply to the division. If there are multiple bonuses of different types they all stack together additively.

Division Examples

Strategy

Stat optimizations

Often it is necessary to optimize a Division for a certain, likely battlefield or role. Doing so requires the mixing of the right Battalions and Companies.

Understrength stats

When a division is understrength its stats are reduced in the principle of how many troops are present to operate how much available equipment. When out of combat the overall "Current Fighting Strength" ratio is determined by taking the minimum of the manpower ratio and the IC-weighted equipment ratio. The stats of the division are the stats of all its battalions and companies combined in ways described above, which are calculated differently from the overall strength ratio. For each battalion (company) the equipment stats are scaled by the lower one of the manpower ratio and the unweighted equipment ratio for each type of equipment the battalion uses, and the subunit stats (including terrain modifiers but excluding organization, recovery rate, and combat width) are scaled by the manpower ratio only, unless the battalion (company) uses "essential" equipment, in which case all the stats are further scaled by the IC-weighted ratio of the respective essential equipment. All the equipment of all support companies and the mechanized battalion is essential, except that infantry equipment is not essential to the engineers company.

Organization & recovery

This is perhaps the single most important stat. And there are two groups of Battalions that are good at it: Foot Infantry and all Mobile Infantry.

Tanks, Artillery and Support companies are the parts that are lacking, sometimes severely so. So you need to bring just enough Manpower into the mix, to have an effective fighting force. However, note that a lot of doctrines actually offset those penalties for some specific Elements, allowing you to use them much more freely.

Maximum speed

If you want anything more than the 4 km/h of an Infantry Batallion, you have to limit yourself to a combination of Tank and Mobile Battalions that suits your needs. Even just a pure mobile infantry. Artillery has to be limited to support companies, and/or provided by motorized/tank variants.

Suppression

Most infantry provides 1 to 1.5, while tanks provide 2.5 and artillery/Anti-Tanks provide 0.

However, the cavalry and bicycle infantry provides 2 which can be buffed further with a Military Police Support Company. Yes, there is actually something Cavalry is good at - playing police! Do mind that they cost more supply and equipment, however. Considering that losses due to resistance are calculated by manpower factored vs (1-hardness), soft units like infantry and cavalry employed see a nation suffer higher casualties compared to light tanks or armoured cars.

Reliability

This is the average of all equipment. For a lot of cheap equipment (Infantry Gear, Support Gear, Motorized) the 80% default is enough. However mechanized and tank divisions can benefit a lot from it, as they have the most expensive equipment.

Aside from investing XP into the reliability, the Maintenance company helps.

Soft attack

Infantry already provides plenty of soft attack/width. 1 Artillery easily provides 3 Infantry Battalions worth of Soft attack for half their width. Even light tanks and Mechanized lean more towards the Hard Attack side.

Hard attack

While everything - even the Infantry equipment - has some Hard attack, usually the soft/hard ratio is in favor of killing infantry.

Tanks shift the balance more onto the side of hard, the heavier the better. Anything with Piercing will also do good Hard Attack. AA can also be somewhat effective at dealing hard attack, being half the damage of a AT Gun.

Air might also be an option.

Air attack

Obviously AA is good at this. It seems unlikely that Armor, Hardness, Defense or Breakthrough has any effect.

Breakthrough

Simply put, tanks are the best at this stat. Heavier is generally better, but the Modern beats the superheavy. Artillery also provides a decent bit, but of course mechanized Infantry the most aside from tanks.

Defense

Infantry is the top thing here. The need for mobility limits the buffs from support weapons passive research. Mechanized Infantry actually adds it's defense to the equipment derived one, easily beating 80 per Battalion.

As history has shown, tanks are not good defensive battalions (unless you can get an armor advantage).

Armor

If your armor can exceed the enemy's piercing, then relevant combat bonuses await. 30% of the armor value is determined by the single highest armor battalion, so throw in a single very high armor battalion for that. The rest depends on the average values; try going for high-level mechanized Infantry to provide a high "baseline".

Piercing

If the enemy fields heavy armor, then you need heavy piercing. Piercing works like Armor in that the highest value matters (40%), so always try to throw in one battalion of something powerful.

AT guns provide the best piercing, up until the T2 Heavy Tank becomes available (1941). The T2 heavy tank actually has better AP then contemporary AT guns, especially on the Tank Destroyer (tank hunter) variant. Still, as you can field 2 AT guns per 2 width, that might still be enough to increase the average to what you need.

The other 60% is provided by the weighted average of all battalions, and will mostly come from Infantry equipment (either Infantry gear or Mechanized). Do get the passive "Infantry Anti-Tank" upgrades, as they apply to both and can double the piercing values.

Do be careful of mixing any AT gun companies with line battalions of either AT guns or tanks. This is because AT companies have lower piercing which will lower the overall average division piercing and Organization.

Hardness rating

This is entirely based on how mechanized the army is. If you want a high value, then mix heavy tanks with higher mechanized infantry.

Forts

The Heavy Tank, Engineer Company and all Artillery except AA provides some bonuses. Super heavy tanks and to a lesser extent super heavy tank destroyers have by far the highest bonus. However, this uniquely has no penalties (as those are already rolled into the fortification mechanic itself).

Amphibious assault

Or "how to win D-Day".

As their name implies, Marines are best for the job, followed by baseline infantry. All artillery Battalions suffer penalties as do Tanks based on heaviness. The engineer Company provides a huge bonus.

You will be dependent on Support companies for many strategic needs.

Rivers

Every River is a little Amphibious assault. Units suffer half the penalty of Amphibious Assaults, but it is applied to movement as well. The only additional exception here is the Cavalry which actually performs worse than baseline infantry. Still, if an overrun is wanted, then it might be worth it.

Hill & mountain assault

The first choice of course are Mountaineers. Of the tanks, the lighter ones have a lower penalty. Mobile Battalions of all kinds also perform with lower penalties. All Infantry battalions only suffer movement penalties at worst.
