Looking at my copy, there is a typo, it should say the Germans score the marker on round 1. It does say that for round 2 and 3. For rounds 4 and 5 it says, "All" meaning either the Soviets or the Germans score the marker. It should have also said that on round 3, another typo. To recap, rounds 1 and 2, the Germans score the marker, 3, 4, 5 both sides can score the marker.
Any chance you will write more scenarios?
