Thanks MadrRasha!
T-70: Seems I've been using that one too kindly
Going to try to use it with more aggression next time. I've always been holding it back, figuring it doesn't stand much of a chance due to low armor value.
T-34: I know how to use this one, I know it's not meant to take on an enemy tank alone, but apart from that game I mentioned earlier on, I never had a feeling I needed them. Rushing SU-85s seemed like a more valid strategy, until I met the Tiger response
SU-76M: I confused this tank with the heavy assault call-in
However, the SU-76M could be a replacement for my ow so beloved 120mm Heavy Mortar.
Ostwind: Like I said, going to try to use this one more often.
Stug III: I have a feeling most players skip this one all together.
