How Is a Division Template Structured?

What a division template is

In Hearts of Iron IV you do not assemble every division by hand on the map. You build a template — a recipe: which pieces go inside, how many, and in what order.

Then the game stamps out divisions from that recipe: infantry, tanks, garrisons, and so on. Change the template — every division of that template starts updating toward the new composition (you need manpower, equipment, and time to reinforce).

You open this in the division designer. On the left — the composition grid; on the right — the stats summary. Division stats are the sum of its composition (battalions, companies, regiments) plus bonuses from doctrines, commanders, and the rest.

What a division is made of

A normal combat template has three “layers” of composition. They are easy to mix up, so keep this simple picture in mind:

• Line battalions — the main grid in the center. Infantry, artillery, tanks, motorized, and so on. This is the “meat” of the division: damage, organization, combat width.
• Support Companies — a separate column on the right (the “Support Companies” tab). Engineers, Recon Companies, Field Hospital, Logistics Company, support artillery/AT/AA, and others. One company of each type per division; they do not add combat width.
• Regimental support — a row under the battalion columns. Available when that column already has enough battalions (at least 3 battalions in the column). Also no combat width.

Short version: battalions are the core of the fight, companies are buffs and special roles for the whole division, regimental support strengthens a specific column.

What battalions are

A battalion is one combat slot in the template grid. Add an infantry battalion — the division gains manpower, rifles, organization, defense, and a chunk of combat width. Add an artillery battalion — more soft attack, but usually less organization and higher supply use.

Battalions come in different roles:

• Infantry / special forces / cavalry — hold the line, provide organization and defense.
• Motorized / mechanized — move faster, often paired with tanks.
• Artillery / rocket artillery — push soft attack, burn supply, and “dilute” organization.
• Tanks / SPG / Tank Destroyers / SPAA — armor, breakthrough, hard attack, AA — the backbone of an offensive.
• Line AT / AA — when you need a lot of piercing or anti-air right in the line.

Battalions decide what the division is: infantry for holding, tanks for breakthrough, or a garrison for suppression. Without combat battalions, there is essentially no template.

What support companies are

Support Companies are not “another line of infantry”. They are a separate block in the designer: up to five slots on a normal division. Each slot is one company of its type. You usually cannot place a second copy of the same one.

Why they matter: they give the division what battalions lack, without inflating combat width. Example roles:

• Engineer Company — entrenchment, defense, rough terrain.
• Support artillery / AT / AA — a bit of damage or protection without extra width.
• Recon Company — better tactic picks by the commander in battle.
• Field Hospital — fewer permanent manpower losses.
• Logistics Company — lower supply use and better equipment reliability.
• Signal Company — initiative and how fast you enter combat / planning.

Do not mix up the names. “Support Companies” is the tab with all of these companies. “Logistics Company” is one specific company from that tab (logistics), not the name of the whole tab.

What regiments and regimental support are

In the designer, battalions sit in columns. Each column is essentially a regiment. A normal division has a maximum of 5 columns, with up to 5 battalions in each.

Regimental support is a separate slot under a column. It strengthens the division (often defense or punch), but it does not unlock right away: that column needs at least 3 battalions. Otherwise you cannot place the slot.

How it differs from support companies, in plain English:

• Support Company — one for the whole division, in the shared column on the right.
• Regimental support — tied to a column; you need the regiment “thickness” of three battalions.
• Both companies and regimental support do not add combat width.

For a beginner the rule is simple: first build a proper line of battalions, then support companies, and only then think about regimental support — if the columns are already “thick”.

How the designer grid works

Looking at the designer screen from top to bottom:

New columns and support slots cost army XP. So a template is not only “what looks neat on the grid”, but also “what XP and industry you can afford”.

On the right in the designer — the summary: organization, attacks, defense, breakthrough, armor, combat width, supply use. Change one battalion — the numbers move right away. That is how you learn to read a template: watch what went up and what dropped.

How this looks in practice

1. Open the designer and take a basic infantry template.
2. Fill combat battalions into the columns — that is the skeleton of the division and its combat width.
3. Add 2–4 support companies for the job: engineers almost always, then artillery/AT/AA/recon as needed.
4. If a column already has three or more battalions — optionally add regimental support.
5. Check the stats summary: organization should not “die”, width should fit fights, supply should not burn the country dry.

A beginner’s starter idea: “9 infantry + engineers + support artillery” — already a clear defensive division. Later you move into tanks, SPG, and fine-tuning for meta combat width.

Common mistakes and tips

• Mixing up companies and battalions. A battalion gives width and the core of the fight. A company is a booster without width.
• Mixing up “Support Companies” and “Logistics Company”. The first is the tab. The second is one company about supply and reliability.
• Stuffing regimental support into empty columns. Without three battalions in the column the slot will not open — first build the regiment’s “thickness”.
• Thinking more = better. Extra artillery and vehicles tank organization and burn supply. A template should survive in combat, not only look pretty in the numbers.
• Changing a template with no stockpiles. After an edit, divisions need manpower and equipment. Otherwise it looks top-tier on paper and holey on the map.
