I was playing a game vs a hard cpu
T-70(light tank) will lose vs an Ostwind("medium" tank/Pz. IV variant), seems ok to me.
penetrating the front armor of ostwind,which is stupid since it's a Panzer IV chassis.
Later that day i tried US-Army vs wehr. they got StuG,so i clled in a pershing. But the StuGs front armor reflected some of the pershings rounds! i didn't even know that the pershings main gun could be stopped by anything lighter than a tiger or at least panther??
