Idk if its just me, but I get this horrifying team game scenerio in my head with Brits feeding resources to the USSR so that they can just mass produce IS-2s (which are superior to Panther tanks...) Also, how is the PE gonna fare in this mix? I don't dare to imagine the Luft or SE doctrines valid at all once the USSR comes in, and even then the Tank Destroyer doctrine will be outgunned compared to those Soviet tanks... Maurder? lol Not to mention USSR trenches...vs the PE... IS-2 is not even a call in I believe... (I read the guide...seems buildable)
