Wow, what, folks lose late allied infatry ? You mean cons ?
Did you forget that cons get late game bonus in recived acc. so they theoretically more HP than any other infantry ?
Are they? I build the Schweres HQ almost every game. And floating 400mp is pretty common as OKW. So if I wanted I could build Obersoldaten in almost every game I play (2v2 player mostly).
They come late. You need to rush them in order to build them in resonable time. And if you go mech truck allied infantry will otscale you mid game - that why almost everybody use some call in infantry (as pseudo elite infantry)
