Combat Width Redesigned

Combat Width Redesigned breaks the tyranny of 20w/40w divisions and allows you to design historical or interesting division templates without being unduly punished. All while still respecting game balance.

  • The penalty for going over width is now 1% per point rather than 2%. This means that the amount of stats your divisions lose when going over width is directly proportional to how much you go over. If you go 10% over width, your divisions lose 10% of their stats.

  • Base combat width is set to 96 and attacking from another direction adds a further 48. This means more/larger divisions can enter combat and makes the more historical 24 width divisions the 'optimal' layout (though not necessary, due to the above change)

I've always been slightly bothered by how combat width forces players into optimal, ahistorical division templates by punishing the player unless they fit exactly within a certain template. 7-2 divisions being a particularly egregious example.

This mod is an attempt to lessen the need to do this and free up player to design divisions based on their industrial capacity and historical inclination.

Do note that, as explained to me by far cleverer people here, due to the way numbers work in the game, you can never entirely make an exact 1:1 ratio of width reduction to penalty, however this mod makes the difference minimal.

As we're no longer constrained by the need to create optimal divisions, here's a few resources to create historical templates:

Not as of yet, though it's definitely something i've considered. The main issue being most big mods change that in someway so it'd be hard to make compatible.

this is very good! Does this change the AI's division designing too?

Changing the existing Artillery unit gun count and combat width is a major deal. You have to ask yourself should the combat power of the Artillery unit stay the same with any gun count change? Ideally the artillery battalion should have 12 guns and a combat width of one (1). That gives you the basic building blocks to build historical divisions. But it would require an adjustment to the artillery equipment combat power.

For now, I would leave it as it is.

But consider changing the Anti-Aircraft battalions to a combat width of zero (0).

You are correct in that the amount of guns assigned to an artillery unit doesn't effect the combat stats. It only effects the cost. Basically true with all equipment types.

Western and Soviet style artillery battalions usually have 12 guns. Typical Western division will have 3x Light/Medium artillery battalions and 1x Heavy artillery battalions for a total of 48 artillery pieces. Soviet Artillery Regiments were organized differently (24 or 36 guns per regiment, being a mix of Light and Medium/Heavy) and were used differently than Western style, so could be excluded for now.

@barry & @Hans

Interesting stuff. What do you guys think about rejigging the artillery battalion to be 18 guns and 2 width? From what I can gather 3 batteries of 6 guns usually made up a battalion. 3 of those would then make up a regiment of 54, which feels about right historically.

From what I can gather the amount of guns in a battalion doesn't effect it's stats, weirdly, so this change would make artillery more combat effective and resource efficient.

Someone below asked for historical WWII Soviet TO&E's. If you are still looking for those, let me know and I can point you to a source.

Yes, a problem in HoI4, related to historical divisions, are the artillery unit being a regiment/brigade, not a battalion. Other problems are lack of heavy artillery, support units being companies and manpower sizes.

Would warn you that the references above to historical divisions, are not entirely correct. Mainly on how one interpets the source numbers. But are a good starting point.

To properly handle Corp/Army level assets is beyond what this mod wants to accomplish.

Bottom line, the mod does an excellent job of addressing the combat width restrictions in the game.

@mosser1989 tbf, in Hoi3 just pick regiment/brigade into division out of 5 slot while in HoI4 you can create any style of regiment/brigade

main problem of HoI4 division design is some battalion is not battalion but regiment/brigade ie. 36 gun artillery battalion while it should be 12 gun

@LieutenantVixen at that point your playing HOI3 lol

This should just be in the vanilla game I think. It's definitely a problem that historical sized Divisions don't fit the game's meta. And it's also a problem that we are limited to 5 Support Companies. Because that makes it impossible to make historical Divisions too.
