One of the Schwerpunkt Series games, this covers the Soviet offensive and the German counterattacks in Southern Russia from Feb - Mar 1943.
Each side has a chance to attack in this game and the sliding victory scale makes for a tense game as each side tries to hang in for another turn.
A lot of variables in using chits for combat, game turns broken into multiple Soviet/German segments and never enough command points to do all you really want to do.
