With this guide, you’ll be able to assemble the most competitive multiplayer division templates in Hearts of Iron IV. You’ll find the exact layouts and equipment choices for armored breakthroughs, amphibious landings, mountaineers, marines, and mechanized forces used by top-level players, along with tips on why each setup works.
Quick answer
| What | Answer |
|---|---|
| Main tank destroyer chassis | Medium TDs and heavy TDs |
| Best amphibious count | 12 amphibious divisions |

Build medium tank destroyers first
Medium tank destroyer templates are standard for competitive multiplayer, especially early armored roles used by Germany and Russia. The design focuses on cost efficiency, versatility, and reliable hard attack.

Switch to heavy tank destroyers for tougher fronts
Heavy tank destroyers are chosen by Germany and France for landings and high-stress armor pushes. The build targets higher stats and armor, sacrificing some flexibility and cost efficiency found in medium TDs.
Germany sets up heavy TDs with the advanced high velocity cannon as the primary gun and a free turret. Three small cannons maximize firepower, though recent patches have made them harder to fit into heavy tank designs. The setup insists on 17 armor clicks and radios for added breakthrough, although running fewer radios is possible once green air is established. The new balance changes create a noticeable nerf for heavy tanks, and division designers must decide if stats or cost are more important.
For D-Day landings, heavy TDs can reliably pierce and resist enemy delay divisions, especially when anti-air is needed and terrain penalties are lighter. Heavy TDs are less effective than medium TDs in rough terrain, so their best use is in controlled, open fronts or landings.
French heavy TD builds often echo the German setup but can skip radio if air superiority is guaranteed. Some templates stack armor or swap to medium turrets for cost, occasionally using welded armor for a small bonus.
Heavy tank designs with multiple small cannons are now less optimal than in previous metas; consider checking if medium TDs fit your needs after the latest updates.
Use amphibious divisions for the first landing wave
Amphibious templates are used by the UK and USA for coastal invasions, aiming for effective landing power with limited special forces slots and high IC efficiency.
Recent game versions recommend 12 amphibious divisions as optimal for a landing wave (two per tile). If using older guides, double-check division counts before committing production.
Set up paratroopers and bar infantry for D-Day support
For supporting major operations like airborne landings or D-Day, countries such as Italy, Mexico, and the Soviet Union field specialized infantry templates built for efficiency and resilience.
Italy’s paratrooper D-Day template exhibits modded access to regimental support companies with only one battalion, which is not possible in vanilla gameplay. Paratrooper battalions offer improved defense (15), slightly higher organization, better recovery rate, increased soft attack, and lower supply use compared to standard infantry. This makes them ideal as support elements behind main attacks.
Mexico’s “Jamal” divisions are built with four light tank elements, adding substantial hard attack, crucial against armored threats but expensive to field in large numbers.
Bar infantry in Soviet and Italian setups prioritizes a 16-width template, allowing for standard deployment numbers. The build includes field hospitals for HP, signal companies, logistics companies, support anti-tank, and infantry guns—ensuring reliable defense and reinforcement.
- setup build condition
- cheap easy addition
Regimental support company access with only one battalion is not possible in vanilla Hearts of Iron IV—these templates are modded. Standard vanilla division rules apply for official play.
Build mountaineers for Japanese terrain fights
Japan fields 33-width mountaineer divisions with one line anti-tank, tailored for the mixed terrain combat in Asia and defense against Allied tanks, especially in India. The anti-tank component is mainly used where enemy armor is present, offering piercing and hard attack.
Mountaineers are also assigned garrison roles; Japanese bonuses for special forces make them strong defensive units, even compared to normal infantry. Once a naval landing passes the amphibious attack threshold, marines provide diminishing returns—a template combining half marines and half mountaineers becomes optimal. Mountaineers perform better in hilly or mountainous terrain, such as the Philippines, where geography favors their abilities.
Add mechanized support for D-Day world mech pushes
Mechanized breakthrough templates, seen from Bulgaria and Spain, use low-cost, mixed divisions for assault and support roles.
The Bulgarian variant integrates light tanks with a tank destroyer-style build, keeping production costs down while dramatically boosting hard attack and piercing. Mechanized battalions are cheap relative to their value, and light tank elements grant punch against armored targets. Spain’s version drops the light tank for lower cost but retains the basic structure.
Armor engineer companies are added for maximum entrenchment, improving resilience when holding or pushing. These templates excel at supporting large operations with reliable stats and high efficiency.
Also worth knowing
- Heavy tank builds are less favored after small cannon changes. Recent updates nerf heavy tank flexibility, so check whether medium TDs fit your needs.
- Support company access in paratrooper templates may be mod-dependent. Vanilla division designer rules prevent regimental supports with fewer than three battalions.
- Armor memes and SPAA divisions have terrain and anti-air bonuses that need more explanation. Explore their effectiveness if you plan for unconventional builds, especially in air-heavy environments.
- The campaign map appearance may differ. Screenshots show a modded map aesthetic, so visuals may vary from vanilla.
Frequently asked
What is the best amphibious template size for a D-Day landing?
A 14-division amphibious pool is enough to cover one landing wave when the goal is two amphibious divisions per tile. That count lets you spread forces across multiple coastal tiles instead of stacking everything on one point. The exact division layout can vary, but the landing pool size is the key benchmark.
Why use tank destroyers instead of only normal tanks?
Tank destroyers are built to stack high hard attack and piercing while keeping useful armor and cost efficiency. Medium TDs are used for cheaper, faster terrain-friendly templates, while heavy TDs are chosen when higher stats and armor matter more. They are especially valuable when enemy armor needs to be pierced reliably.
Why do some infantry templates stay at 16 width?
A 16-width infantry template appears as a standard defensive layout in the bar setup. It pairs with support companies like field hospitals, signal companies, logistics companies, support anti-tank, and infantry guns. The width choice is part of keeping the division efficient enough to mass in multiplayer.
Why are mountaineers used for both combat and garrison roles?
Mountaineers remain efficient special forces because they perform well in rough terrain and can be fitted into compact widths. In the Japanese setup, they are used even for garrison-style duties because the country’s mountaineer bonuses make them unusually strong. They also help when fighting in mountainous regions like India or the Philippines.
