Worse still would be +3 Infantry in Ukraine I think. Gives Germany a real shot at taking Caucasus with enough to hold it on Germany 1.
Transport in SZ 50 +1 IPC for Japan is deadly too.
Submarine in SZ 8 is kinda deadly too, forces Russia into making a move she does not normally have to make against Norway.
+3 Infantry in Belorussia guarantees that Karelia can be stacked hard enough it will never fall as well.
(6 infantry from Belorussia, 3 Infantry from E. Europe, 3 Infantry from Norway, 2 Infantry from Germany plus all the tanks that can reach on Germany 1 is going to be one helluva stack for Russia to deal with. Nice airbase for Germany too.)
