Best Army Composition? In mid game (Level 8 - Level 14) when the supply limit averages 25-30, I use a 30 stack (16/2/12) notice infantry is approximately 150% times the artillery and by merging two 30 stacks I get a 60 stack (32/4/24) which has a formidable back line considering max combat width is 29, adequate infantry to fill the front. In terms of cavalry the major benefit is flanking, being able to attack the same units as outside regiment infantry. There is no quicker way to shred your own armies than marching into an enemy that is positioned in a mountainous province and taking a river crossing while you are at it. Cavalry depends on unique ideas(e.g. By using our Services or clicking I agree, you agree to our use of cookies. For nations without built in ICA you might want to for for 8 or 10 cavalry to utilize flanking bonuses better. If you have cavalry bonuses (especially to combat ability but cost is important as well) then you'll want to push more cavalry into your armies, usually just a bit under your tech group's maximum. Also be careful with your supply limit, going at war with a filled-up front and back row can drain your MP pretty hard until the lategame.
I can explain a lot to you since I read it in a guide myself however, it is good to read the guide yourself directly cause it is possible I miss out a few good pointers. However from the back line of combat they have a 0.5x damage multiplier, so at mil tech 15 their fire multiplier is effectively 0.7 and they have just one or two pips - imo at this point they aren't worth the money to keep aside from siege bonuses. Cavalry move faster so they can occupy far flung places a bit quicker. This allows me to break siege detachment and still have enough infantry left to not incur the cavalry ratio penalty. I strongly recommend that you read the link, but to summarize what it says: Artillery should be equal to the combat width any extra is useless, since your artillery should never take casualties. Each province can recruit one regiment at a time, though multiple regiments can be queued up in a single province. The maintenance cost is nearly prohibitive of that unless you are kebab or something OP and if you are that OP you can crush armies with shear numbers advantage. At first only attach 1-3 artillery to your stacks to help with sieges, later game (18th century onwards) you should have as much artillery as your combat width to destroy enemy in the fire phase with the first salvo. Why a 60 stack army? Hearts of Iron IV is the sequel to Paradox Development Studio's game Hearts of Iron 3. Usually I like to go with 4 cavalry when playing those two, its especially useful when invading a large country whose army you don't fear but whose territory would take a long time to occupy without splitting your troops up. Supply limit determines how big an army you can place in a province without taking attrition.
