HOI4 Infantry Templates 2026

If you want infantry templates that consistently perform in Hearts of Iron IV, you need the right mix of doctrine, division width, and support companies. This guide covers practical setups for both offense and defense, and explains which choices matter for your country's manpower and supply situation.

Quick answer

What	Answer
Best offensive doctrine	Mass Assault, right side
Best defensive width	16 width
Must-have support companies	Field Hospitals and Logistics
Anti-air and anti-tank	Support AA and support AT
Good offensive country	Soviet Union
Key defensive tactic	Last stand micro

This page covers infantry templates only — offensive infantry for long fronts, 16-width defensive infantry, and the support companies each one wants; for widths, tank divisions and the rest of the template range, see HOI4 division templates after the Thunder at Our Gates rework.

Choose the right infantry role

Deciding whether your infantry divisions are meant for offense or defense shapes every part of your template.

Offensive infantry is designed to grind the enemy down across wide front lines. It works by pushing, draining equipment, organization, and manpower over time. Compared to tanks, it isn't as effective per combat width, but its production cost is much lower, making it ideal for countries with lots of manpower and industry and fronts stretching dozens of provinces. Aggressive battle-planning is the standard tactic — keep pressure steady, accept early losses, and wear down the opponent.

Defensive infantry, on the other hand, is mainly a stopgap. Its job is to buy time until tanks or specialized offensive units can mount a decisive breakthrough. Defensive divisions need high organization, so they stall attacks for as long as possible, letting superior firepower build up elsewhere. Templates and doctrine choices here prioritize reliability over outright destruction, using narrower divisions and support companies that improve staying power.

Infantry is most efficient on large front lines, where you can field many divisions and take advantage of sheer numbers and production efficiency. It's rarely as strong per combat width as armor or mechanized, but it is much easier to mass-produce and keep supplied.

Build offensive infantry for long-front pressure

setup required before deployment
cheap easy optional upgrades

Select Mass Assault doctrine (right side) setupUnlocks higher HP, recovery rate, reinforce rate, and reduces infantry battalion combat width. Enables you to build larger divisions without sacrificing org. Vital for offensive infantry performance 0:01
Build large (high-width) infantry divisions setupIncrease combat width to maximize HP, breakthrough, and defense. Larger divisions suffer fewer losses ('crits') and can sustain pressure longer, especially with Mass Assault's combat width reduction features. As big as supply and org will allow 1:00
Add heavy tank battalion (optional, high-IC games) cheapInclude a heavy tank battalion if rules and industry allow. This raises division armor but is not required for standard offensive infantry. For nations with exceptional industry 1:28
Add line AT only if tanks are ubiquitous cheapLine anti-tank (AT) battalions should only be added if the enemy fields tanks on nearly every tile. Otherwise, focus division setup on defeating infantry. Specialist option for tank-heavy opponents 1:36

Pick the support companies that matter most

The support companies you pick for offensive infantry will make or break your division's durability and supply flow. Here’s how the most common support options compare:

Support Company	Benefit	When to Use
Field Hospitals	+10% HP, reduces manpower and XP losses	Always. Essential for all offensive infantry templates
Logistics	Improves supply efficiency, supports larger armies	Always. Needed to keep numerous divisions supplied
Support AA	Provides anti-air, lowers enemy air superiority impact	If enemy has green air on your front
Support AT	Ensures partial tank piercing	If enemy has tanks present, especially in multiplayer
Support Artillery	Cheap soft attack boost	Flexible. Replaceable if you want other companies
Signals	Raises reinforce rate and coordination	Useful for additional reinforce; especially late-game
Military Police	Recovery rate boost	Optional
Engineers	Offensive breakthrough, terrain bonus	Optional
Rocket Artillery	Soft attack, tech-heavy option	Optional; late game, if research/IC allows

Key stats like HP, soft attack, and manpower are visible on the right panel. — The support row shows which slots are being treated as core picks versus flex options.

Tip

Aim for Field Hospitals and Logistics as core picks. Add AA and AT if your enemy has air or tanks. Signals, Engineers, Military Police, and Rocket Artillery are flex slots – adapt them to the late-game or match-up.

Use offensive infantry in the right country and situation

The best offensive infantry strategies depend heavily on your nation’s manpower pool and front size.

The Soviet Union is ideal because it has huge manpower and long front lines, making it possible to deploy dozens of divisions and sustain losses other nations could not afford. Other large countries can use the same approach if they have the industrial capacity and conscription laws to field large armies. Smaller nations can replicate the setup, but results will vary and overextension is a serious risk.

This approach requires patience: you’ll often see red battle bubbles early in the campaign, indicating losses. Stick to the plan — your goal is to force the enemy to run out of equipment and manpower before you do, not to win every individual battle immediately. Production and steady reinforcement are what matter most.

Design 16-width defensive infantry

Set division width to 16 Best organization-per-width ratio 4:53
Avoid widths below 10 Losses rise dramatically below 10 width
Choose Mass Assault doctrine if possible Provides superior organization and reinforce rate

Careful

Widths below 10 increase equipment and manpower losses significantly. Stick with 16 for balanced defense regardless of doctrine.

Fill defensive support slots by matchup

Support companies for defensive infantry depend more on your enemy and terrain than on offensive setups. Here’s a breakdown:

Support Company	Benefit	Use Case
AA	Counters air; lowers enemy air superiority effect	If enemy has air presence
AT	Pierce tanks; useful if enemy uses armor	If enemy has tanks; can be skipped if industry is tight or tanks are over-armored
Signals	Reinforce rate boost	Mandatory for non-Mass Assault doctrines to avoid reinforce penalties
Logistics	Supply efficiency	Optional; skip if front is well supplied
Engineers	Defensive terrain modifier boosts	Optional; use in rough terrain or urban/river tiles
Artillery/Support Artillery	Soft attack boost vs. soft targets	Recommended vs. special forces or AI; Asia/Japan setups especially
Rocket Artillery	Soft attack; especially effective in single-player	Optional; strong late-game for AI matchups

Matchup

AA and AT are defaults if you face air or armor. Signals compensate for reinforce rate if not using Mass Assault doctrine. Engineers and artillery shine in terrain-heavy and soft-target situations.

Use last stand and tactic preferences on defense

Preserve last stand by general micro Move a unit to another general, activate last stand, then return it. This keeps the last stand active on key bottlenecks 7:17
Keep a spare general with prepared units Positions ready for fast last stand activation at critical chokepoints 7:46
Select preferred defensive tactics in officer corps, generals, and field marshals Mobile Warfare enables Back and Blow, Mass Assault gives Guerrilla Warfare, and Superior Firepower offers Tactical Withdrawal. These modifiers stack 8:16

Timing gate

Stacking preferred defensive tactics boosts your chance to trigger the strongest combat phases for defense, especially useful on tiles where delay is crucial.

Also worth knowing

Before you commit

Micro techniques deserve a deeper follow-up. Many players want more practical control tips, especially for tanks. Consider learning advanced general and division micro beyond last stand and tactic selection.
Country-specific and terrain-specialized templates are in demand. Division design changes against special forces, river crossings, urban combat, or unique national focuses. Template details for these cases would benefit players facing specialized challenges.
Always check template relevance after updates. Strategies and optimal widths can shift after game patches. Confirm that your infantry setup is current before large campaigns.
Support AT is a budget anti-armor fix. Consider using support AT in place of recon for cheaper anti-tank coverage in standard infantry divisions — especially when industry is limited.

Frequently asked

What width should defensive infantry be in HOI4?

A strong default is 16 width. It gives a better organization-per-width tradeoff than wider defensive divisions and still keeps losses reasonable, while widths below 10 become very inefficient in practice.

Which support companies are most important for infantry?

Field hospitals and logistics are the main defaults for offensive infantry. Support AA and support AT become important when the enemy has air superiority or tanks, and signals, engineers, or artillery can be swapped in depending on the job.

What doctrine is best for infantry templates?

Mass Assault on the right side is the strongest fit for offensive infantry in this setup. For defense, the same doctrine is still recommended, but other doctrines can work if you adjust support companies and tactics properly.

What country benefits most from this infantry style?

The Soviet Union benefits the most because of its large manpower pool and long front lines. The same approach can still work for other large countries, especially in multiplayer.
