Tried another scenario of Black Swan the 1942 variation where the Americans finally got into the game.

Richard (British-US), Lee (Soviets) and Jim (Axis). The scenario started as usual with the Germans and Italians over running the map. Once the US entered, the Western Alliance had enough ground troops to be effective. While the Axis was punching holes in the Russian defenses and the Italians taking Africa and the Middle East, the British and US did a dual invasion of Western France and Copenhagen. On the next season, the Allies attacked Berlin and destroyed the fortress. This ended the game.
