Then I played the Russians and, when a Pz II showed into my sights I attempted to fire... and then saw a window stating this gun cannot fire from a building [:(] (If I remember correctly, only AT guns up to 75mm can fire from buildings). I managed to kill the German AFVs anyway using Molotov projectors, ATR fire and the good old reliable CC attack [:D], however I think making this gun functional might make the scenario more challenging for a human German player.
I suppose turning the wooden building into a wooden rubble should do the trick.
