personally? by the time a hetzer rolls onto the field (1v1) idve wasted more than theyve wasted me, so, id have a couple of shermans and MAYBE an M10 by then, plus of course the rifles, snipers, mortars and HMGs. what i do, is id do one of two things depending on the situation
If all he has is just PGs and Hetzers, then you can get some BAR rifles and AT guns along with a few snipers.
