Hearts of Iron IV Best Division Templates & Meta Guide (2026)

2026-06-09·Builds

Key Takeaways

  • The 9/2 (9 infantry, 2 artillery) at 21 width has replaced the old 7/2 as the standard infantry template due to combat width changes in the latest patches.
  • Tank divisions need at least 30 organization to be viable. A 10 tank / 5 motorized template hits this threshold and has enough breakthrough to punch through any line.
  • Marines with Amphibious Tank support are the only way to land on defended ports. Regular infantry dies on the beach — always use specialized invasion divisions.
  • Width optimization matters: plains = 70 width, forests = 84, urban = 64. Design templates that fit cleanly into the most common terrain you'll fight in.

Infantry Templates

Standard Line Infantry (9/2)

BattalionCountCombat Width
-------------------------------
Infantry918
Artillery26
Total24 width

SupportPurpose
------------------
ArtilleryExtra soft attack
EngineersEntrenchment + terrain
Anti-AirIf you can't contest air

Best for: Holding the line, most nations, 90% of situations.

Defensive Line Holder (10/0 + AA)

BattalionCountCombat Width
-------------------------------
Infantry1020
Anti-Air (support)10

Best for: Nations that can't afford artillery, port garrison, suppressing resistance.

Mountaineer Specialist

BattalionCountCombat Width
-------------------------------
Mountaineers816
Artillery26
Total22 width

Best for: Mountain fighting (Alps, Caucasus, Andes). Mountaineers get +40% attack in mountains.

Tank Templates

Medium Tank Breakthrough (10/5)

BattalionCountPurpose
---------------------------
Medium Tank10Breakthrough, armor, hard attack
Motorized Infantry5Organization, HP

Stats: ~30 Org, 500+ Breakthrough. This is the standard offensive template for major nations.

Light Tank Rush (Early Game)

BattalionCountPurpose
---------------------------
Light Tank6Speed, breakthrough vs early infantry
Motorized Infantry4Organization

Best for: Early wars (1937-39) before medium tanks are researched. Light tanks outrun infantry — use them to encircle, not to fight.

Specialized Templates

Marine Invasion (Naval Landing)

BattalionCountPurpose
---------------------------
Marines8No naval landing penalty
Artillery2Soft attack on beach
Support: Amphibious Tank1+40% naval invasion speed
Support: Engineer1+25% naval invasion attack
Support: Signal1Faster planning

Never invade with regular infantry. They take a -70% attack penalty on naval landings.

Paratrooper Disruption

BattalionCount
------------------
Paratroopers3 (keep small, they'll die anyway)
Support: Engineer1

Paratroopers are disposable. Drop them behind enemy lines to disrupt supply, capture undefended victory points, or hold bridges for 24 hours until your main force arrives.

Garrison / Resistance Suppression

BattalionCount
------------------
Cavalry1 (literally one battalion)
Support: Military Police1

Cavalry has the highest suppression per cost in the game. A 1-battalion cavalry + MP template suppresses resistance for minimal equipment and manpower.

Template Design Rules

1. Organization must be >30. Below 30, your division retreats before dealing meaningful damage.

2. Combat width should be ~20-24. Fits cleanly into most terrain types.

3. Never mix tanks in infantry divisions. The speed is wasted, and mixing reduces both templates' effectiveness.

4. Upgrade templates during peacetime only. Changing a template mid-war drains division experience.

FAQ

Q: 7/2 or 9/2?

A: 9/2 for 2026 meta. Width changes made 20-width less optimal. 9/2 gives 24 width and better stats.

Q: When should I switch from infantry to tanks?

A: When you have 50+ MILs on tanks AND enough fuel production. For most minors, never — infantry + air is sufficient.

Q: Best template for China?

A: Pure infantry (mass mobilization). China can't afford artillery. Quantity over quality — 200 divisions of 10/0 beats 50 divisions of 9/2.
