Best Breakthrough templates in Hearts of Iron IV

Four tested, ready-made templates for when the front has to be ripped open: which tanks to field, when Motorized Infantry is enough, and why a minor puts a single Medium Tank into its infantry.

How to pick a template from the list?

Template 1 — «Tanks 36 CW.» For a major, and not from 1936. Germany by 1941 can comfortably run 40–48 of these if you don't spread your factories thin. Rips the front and makes huge pockets. This is usually what top players field as a major. Too early for a minor: check the 20 CW tank template first.

Template 2 — «Tanks 20 CW.» Same idea, fewer tanks. 4 Medium Tank battalions and 6 Motorized Infantry. Crushes minors and weak majors. Against another great power's dense line it's already a bit weak. The minor's real pain is not factories, it is research slots: the tank, the trucks and the companies have to be unlocked before the war to produce these divisions in time.

Template 3 — «Motorized Infantry 20 CW.» Infantry on trucks, no tanks. Speed is huge: find a hole, punch, drive off to make a pocket. It will not crack strong enemy defense. It wants a lot of Trucks, and Rubber for building them too. From my own games I would say those same trucks are usually better handed to the 20 CW tank template.

Template 4 — «Armored Infantry 20 CW.» 9 Infantry battalions and 1 Medium Tank battalion: 50 tanks per division. The tanks move at infantry speed, so no blitzkrieg. Good for a minor before the world war: Argentina vs Brazil — yes, the USSR in 1941 — no. It is a step between «plain» infantry and real tanks.

How to pick. Unsure, but you have at least a few Military Factories on Medium Tanks — take Template 2, Combat Width 20. Template 1 if you are already a major and can feed 36 CW tanks. I rarely field tankless Motorized Infantry: Breakthrough is higher than infantry, but it's still nowhere near tanks. Template 4 if tanks are scarce and you still have to attack the neighbor.

If you are new to HoI4 and understand little here, look at the «Tanks 20 CW» division template. It does not demand insane skills but is still pretty good. Just concentrate these divisions instead of spreading them along the whole front. Now let us look at the templates themselves.

4 ready-made Breakthrough templates

Four tabs below. «Breakthrough» in the designer is a stat, not the Breakthrough line on the map (that one is a separate order). Almost all Breakthrough sits in tanks. Two or three battalions of good Medium Tanks in a mixed division often do more than a whole Motorized Infantry division without them. Combat Width is how much room a division takes in a fight. A typical tile is around 80: a 20 CW division takes a quarter, a 36 CW one almost half.

  • For a major
  • Offense
  • Tank

This is the gold standard I run as a major once you have enough factories. 8 «Medium Tank» battalions and 10 «Motorized Infantry» battalions, support companies built for attack. Supply is tight here: without a «Logistics Company» the division runs out of supply fast, and all that Breakthrough is only on paper.

Template description

Why not regular engineers? The «Assault Engineer Company» is built in HoI4 for attack, the division's main job. Without it and without the «Medium Flame Tank Company,» terrain punishes you hard, as if the tanks were made of plywood. The «Armored Recon Company» uses Light Tanks (24) and slightly softens those same terrain penalties.

The «Logistics Company» matters a lot here. A 36 CW tank template eats a huge amount of Supply. Without logistics you'll often be out of supply, and then even 400 Medium Tanks ride like a tractor with no diesel. Logistics costs 20 Armored Cars per division.

Per division: 17 900 Manpower, 1000 Infantry Equipment, 360 Trucks, 400 Medium Tanks, plus 15 Medium Flame Tanks, 24 Light Tanks for recon, 12 Towed Artillery and 40 Support Equipment.

Plenty of soldiers in it, but on the attack the division loses few of them: Breakthrough is high, and the enemy often cannot answer in time. Not an ideal defensive template, though in practice it holds well. Later you swap Motorized Infantry for «Mechanized Infantry»: the stats are a bit tougher and there are more vehicles, but it costs more too.

This is not a minor’s starting template and not «spam it by September 1939.» Mid-to-late game, a major, lots of Military Factories. No such industry — take the «Tanks 20 CW» tab.

Pros
  • Rips the front: it's very hard to hold against this division.
  • Loses little manpower on the attack.
  • Makes huge pockets if infantry closes the flanks in time.
Cons
  • Very expensive: 400 Medium Tanks per division.
  • Arrives by mid-to-late game, not by your first national focus.
  • Majors only: a minor goes bankrupt.

Verdict. A very strong template, but not everyone can feed it. For attack, for a major, around mid-to-late game. With «Mechanized Infantry» it gets even stronger. No Military Factories — do not copy it.

How to use it

Do not stretch 12 of these one-by-one across Europe. Mass them into a fist: several divisions on one tile. You break the front — straight into the rear, onto supply hubs and railways, while infantry closes the pocket. This is not a defensive wall: if the enemy counterattacks a starving wedge, the «gold standard» turns into scrap metal fast.

Comparing all the templates

Do not look at «who has the bigger number in the designer.» Look at who you are and who you're up against. A mega-major by 1941 — take Template 1, Combat Width 36. A minor that actually managed to build up Medium Tanks — Template 2, 20 CW. No tanks but Rubber is there — Template 3. Very few tanks and a weak neighbor — Template 4. You can «break through» with infantry, but it is slow, bloody and usually wasted: Breakthrough as a stat barely grows.

After the Breakthrough do not linger in the tile you broke through. Go for the rear: railways, ports and supply hubs. A pocket works when the enemy has nowhere to retreat and nothing to eat, not when you simply won one fight. The 36 CW template does it loudly, the 20 CW one more quietly, but by the same principle. Motorized Infantry can drive around if the hole is already there. Infantry with one tank widens the hole slowly and almost never closes the pocket itself.

Bottom line

If you need Breakthrough — you need tanks. Not necessarily a 36 Combat Width division right away: a minor is fine with 20 CW and several divisions on one tile. Motorized Infantry without tanks is faster than infantry, but those Trucks often feel wasted on it. One Medium Tank in infantry is a crutch until a real wedge. Field what your Military Factories can feed, and do not try to replace with infantry what tanks do in HoI4.
