The Eastern Front was the most intense action of WWII and one of the most interesting if not the most imo. Anyone who is unfamilar with it is doing themselves a favour by learning more about it! Beyond that, imo I think in terms of CM, the forces are at the same time more balanced and more disseperate (needing different tactics). Some might disagree, but I always felt the germans with equal point layout always had a slight but significant advantage in CMBO quick battles due to their superior armour. Russian tanks on the other hand are quite potent...
