Sorry for asking, but I’m writing to ask for some advice. I find the Challenging Mode really interesting, but there are two rather big issues that bother me.

One was that the AI doesn’t defend the coasts of its core territories, such as the USA or the UK. I think I managed to fix this (hopefully without causing side effects) by editing the files USA_EAI.txt and ENG_EAI.txt, modifying the following blocks to make the AI defend its coasts:

EAI_USA_garrison = {
allowed = { tag = USA }
enable = { always = yes }
abort_when_not_enabled = yes

ai_strategy = { type = garrison value = 250 } # was 50
}


and

ai_strategy = {
type = put_unit_buffers
ratio = 0.20 # was 0.01
states = { 351 352 353 354 355 356 357 358 359 360 361 362 }
subtract_invasions_from_need = no
subtract_fronts_from_need = no
}


Now I only have one last problem left to solve: I’d like to make all the major nations use medium tanks more extensively, but I don’t know which files to modify.

Could someone give me some suggestions pls?
