Three Russian Guards counters (Eng, 82mm, SMG) were missing from mix so regular units had to be substituted. Russians have large advantage in units and simply ran over German defenders. Germans may have been able to hold out longer with a better defensive setup, but Russians had more than enough firepower to quickly eliminate the few good units the Germans had. A Sturmovik attack, a flank JSII shot, and an infantry assault in a town quickly eliminated the Tiger II's and the Luftwaffe 88mm didn't last much longer. It might be worth trying again, but the Soviets will hold a decided advantage regardless.
