This is one of the few PG scenarios that I have felt is poorly designed. The scenario is too long and there is no mechanism to prevent the Soviets from winning by just waiting until 4 turns before the end before advancing within range of the road. The Germans could try preemptively attacking them but this throws away their mobility advantage on the defense, and they don't have the superiority necessary to finish the job.

It could be improved a lot by making it a 12-16 turn game, forcing the Germans to knock the Soviets out and forcing the Soviets to commit to an advance.
