I thought i would just suggest this as a Defensive map for the Russains. It seems like it would be a interesting map. The Russains would be only be armed with Anti Tank Rifles, MGs and other small arms Although they would be in a fortified apartment building. While the Germans would be armed with tanks and other heavy equment but exsposed on open ground.
