CP0:Breakthrough tactics. Pretty niche ability specially in early game, but in late game can give advantage in big attacks. Capture enemy cutoff rapidly, or capture that victory point before you bleed to death.
CP1:
CP2: Panzerfüsiliers, look below.
CP12: Assault artillery: I kinda like this artillery barrage, because it targets the whole sector and gives smoke cover. But it is very expensive and so easy to dodge.
CP13: Jagdtiger: I have mixed feelings about this unit. This used to be epic OP BS unit shooting through buildings all the time. It is still good, but it cant kill infantry. I feel it is much safer to buy a KT insted. The barrage ability is kinda crappy and expensive. Piercing shot OK.
I rarely see Panzerfüsiliers built. They need G43, otherwise they are pretty meh. But OKW ammo in early game must be used to panzerschrecks, because raketen is so crappy. Their flare is kinda meh, but can be good with stuka. Their grenade model 24 is kinda bad. AT grenade sometimes is handy, but it is bugged as hell like USA at nade. And when you can finally afford G43s to your panzerfusiliers, if you have bought 4 schrecks like OKW normally does and then lay some mines, you are able to buy Obersoldaten, which spawn with free LMGs. The biggest problem in this commander is, that it needs so much munitions to be effective.
And this commander havent got MG34 and pak43, the safest okw meta..
