That's not the point though. The point is that he croc is easily countered by any non ostwind tank, so it really shouldn't be an issue. This was after a game, when you can hit "continue playing" so I called in a croc and made it 1v1 a vet2 stug and it lost. To a 90 fuel tank destroyer. So anything equivalent to the croc in cost should counter it easily, or at least force it back if 1 stug can.
Easily countered? You are forgetting there is an entire army supporting that huge driving health pool fire shooting mammoth of a tank? I understand your point that a vet 2 stug will beat it 1v1, but it never is a 1v1 fight. Whilst your stug is trying to kill it, it will have burned your pak40 to death, raped a few mgs and is burning your grenadiers whilst you have to deal with tommies, most likely a mortar pit, a 6 pounder and perhaps a vickers.
The same goes for facing a KT as soviets. The KT will be beaten at range by a SU85, but that KT is supported by multiple rakettens, volks, a sturmpioneer and perhaps an leig and a mg.
