In 1vs 1 ostheer is viable.
It sniper is still insanely strong agains 4 men british sqaads.
Brits dont have counter to mg except carrier that die to pfaust and expensive mortar emplacement.
Grens are weaker , but they have better support.
And you can aways go 3 ostruppens with 3 mgs into 2 222.
Agains USA snipers work too + teller mines are beast , also mg 42 const usa a lot of munition.
Agains soiets they are balanced.
OKW
I found that okw is only viaable at goint medics + JLI spam into puma into oswind or else they get stomped by USA
Agains brits , double sutrm + fussieliere spam works and if you add 2 luchs you can win even before brits start to snowball
have no osttruppen commander
