HE vs AP tank fire

[pjbandit2003]

Thanks for the info. So what do the Japanese have that is a mobile AT weapon. None of the infantry have AT weapons (with the exception of the polemine) and only a couple of them use them. None in a regular infantry company. The only tank that is listed is the Yi-Go and it is really ineffective against any armor so they really have no AT capability in the early war years? No wonder they lost.

Correct.

The best theoretical penetration for HE for that gun and WH size is 4 which matches the best theoretical "Best AP" penetration and beats standard AP pen by 1

So when does this come into play. The best penetration I can get is 1 at range 1(50m). The only thing I am able to do is assault with infantry and all they have is the type 91 grenade.
