Finger in the air suggestion, but I was always struck how the actions described in Kamen Nevenkins' 'Take Budapest' (Take Budapest!: The Struggle for Hungary, Autumn 1944 - Kamen Nevenkin - Google Books) - the first Soviet attempt to take the city on the run - could form the basis of some good CMRT scenarios/ campaigns (if executed by someone with more talent and time than me....). Two (increasingly depleted) Soviet Mechanised Corps pushing forward against German counterattacks by Panzer Divisions with a few dozen AFV's a piece, and the whole thing compressed into a week or so.
Anything East Front would be appreciated!
