Ideas for Soviet vs polish resistance

[JadolesMasta]

i like the idea of having Polish vs Russian. My main concern is how can a Polish solider take out a IS 2 with molotov. It takes forever. But beside that, i think it will be good. But for historic accuture, it should be agianst the germans since the Poles team up with the russian. But agian the Poles did fight them in the first year of the war.
