A Bagration, Von Manstein's attempt to relieve Stalingrad, Moscow and most interesting (to me) an updated Soviet Offensive 1943b on Black Turn. http://unityofcommand.net/cs/ Now the regular UoC games are nail biters by design and a lot more lively and challenging play; but this SO is a game as vast as Mother Russia herself-and indeed covers the entire front. Give yourself some time if you are going to tackle this monster!
