Depending on what the Soviet player does on their first turn will matter slightly, sinking the American and British transports on the first German turn will allow tons of time to march all tanks and men straight into the heart of Russia,dont forget to take care of Africa aswell leave Southern Euroupe empty. If the Soviet player doesn’t place a really strong defensive gathering in the capital between 25 to 30 infantry than you can fight your way into the capital and still strike with an overwhelming force within turn 3 the game will be decided on this very large battle.The British may be able to aid them with only a couple of fighters by this time so if the Soviet forces can be crushed than you have only a weak UK to contend with. Ofcourse you forces in the Soviet captial may not be a force at all when the battle is over but the Soviet capital will fall. To plunge everything land based into Russia should allow you to dictact what the Soviet player does. If they take Finland on the first turn then victroy is almost certain.
