We played the first scenario from this excellent book last night. Excellent fun, resulting in a German win: the Russians had lost all their tanks, and AT guns, and most of their infantry and the Germans still had all their tanks and about half their infantry.
The Germans were helped by a very lucky Stuka attack which took out one T-26 and left another with a burning engine. Also by the inability of the Russian gunners to hit barn doors: the KV had numerous chances to KO German tanks and fluffed them all, as did two of the AT guns.
German plan of attack was good: they managed to attack the AT guns with infantry and the infantry with armour; it took the Russians too long to rearrange things so it was the other way round.
So looks like the Germans will be trying to seize the bridge at Urk next....
