Attack Karelia with 3 Infantry, 1 Artillery, 3 Fighters, and 1 Cruiser (80% chance of at least 1 ground unit surviving)
Attack Baltic States with enough forces to kill it, but don’t use the tanks in West Poland
Attack Belorussia with 1 Fighter and 1 Bomber
During Noncombat phase, move the 2 Tanks in West Poland to Karelia
End Result(assuming you are in the 80%): You will have 2 Tanks, 1 Artillery, and 0-2 Infantry in Karelia. Russia has 2 Infantry and 1 Tank able to counterattack, which is insufficient.
You will still have enough forces to take East Poland and Ukraine as well, especially if you use the Mediterranean transport.
If Russia loses Karelia first turn and can’t recapture it, they are VERY screwed, and will likely lose Archangel, Belorussia, and Northern Ukraine the following turn, while Italy will either recapture Ukraine or whittle Caucasus further on turns 1 and 2.
G1 should consist of 6 Tanks, G2, of 2 Tanks and 3 Bombers, of which all can hit Moscow on G3.
