After looking at the 45mm gun post, I wonder if the Zis-3 has a place in the mod as a weaker anti-tank gun/ field artillery piece? I think it has a model, and is man-portable, Soviets would drag them up by hand to fire over open sights. It is a cool piece that embodies Soviet tactics, good when massed, direct, simple and destructive. I wonder what it could replace though, perhaps the heavy mortar or the At-gun?
