Pelton, I think the key to defeating this sort of thing is to make use of regimental reserves as Bob explained a while back. A single German mobile regiment reacting can usually shut down a hasty attack, even in blizzard. Reserves, and I'm not sure why this is so, are disproportionately strong in defense reactions. This is equally true on the Soviet side; a single rifle division reacting in reserve mode is stronger than that same division actually defending the hex directly. Reserves seem to get some kind of surprise bonus. (True also I think for offensive reserves, and if both sides get reserve activations, they can cancel each other out.) I'm not sure what's going on here exactly, the code is a mystery, but that's what I see happening.
Reserves, by the rules, have no enemy unit adjacent to them, thusly no fatigue from attrition.
