The only hope the Germans have in this scenario is to hold up in the two towns, bleed the Soviets in close assault, hope their OBA can do some damage to the advancing Soviet infantry and knocking out a couple of steps of T34s or KVs, while keeping their own casualties low because every 10 steps eliminated generates a new reinforced Soviet infantry company. The Germans did just that at first but right around turn 12 the wheels come off, the Soviets finally took the first town and were moving on to the next objective with three fresh infantry companies to replace their previous losses and only one tank step eliminated.
