This is going off the assumption that Germany buys all navy first turn. Germany should buy 7 arty 12 infantry with her 66 dollars second turn and 10 arty 1 mech 1 tank turn 2. turn 3 you’ll have 52 so that is 13 mech. turn 4 will be 11 mech 1 tank. You are setting yourself up for a turn 7 take of Moscow, and a turn 4 DOW on Russia, so now you buy all planes on turn 5. you will have 50 so you can buy either 5 fighters, or 4 bombers. Turn 6 you will have Ukraine so you can buy 3 tanks there. Depending on what Russia did, you should have taken lenningrad turn 5 and now you should have 60 to spend. So after 3 tanks you will have 42 left. That is 3 bombers and 2 infantry. Moscow should now be a 100% chance to take. Try it out and see if it works for you.
BTW. my strategy is to have all my infantry and arty to be outside the gates of moscow on turn 6. Everything that was purchased from turn 2-6 (minus the 2 infantry) will be able to hit Moscow on turn 7. He literally has no way to defend against this. The Europe board, IMO, isn’t won taking Moscow, but taking Egypt. So GL there!
It looks like you won’t be able to hit Moscow until turn 8 with those builds. The 10 arty you build on turn 3 will not reach Bryanks until turn 7, as well as part of your turn 1 build which has to start in West Germany.
