Send 5 inf from Kar/Arch, 1 Artillery and two fighters to West russia and stack everything else in Cauc. Leave one Inf in Lenningrad and do your standard moves on the east end.
Don’t you run into Germany taking Karelia and West Russia, and establishing a strong center position from which Russia cannot reclaim Karelia income?
Bunnies is correct. G takes West Russia with units from BR/Ukr. Russia can retake West Russia but will only earn 27 IPC, not being able to contest Belorussia and Karelia. Germany meanwhile can build 5 inf, 5 arm on G1 and put some serious pressure to prevent Russia from stacking West Russia on turn 2.
The main goal of the Ukr attack is IMHO to get the fighter,
Cutting most of Germany’s ability to attack Caucasus is another big big plus. If Russia lucks out on the Ukraine attack, Germany may either risk fighters on G1 on other targets to send a fighter to Ukraine, or may send valuable tanks to reclaim Ukraine. Or if Russia lucks out at Ukraine, Russia may retreat to Caucasus to preserve its tanks/artillery.
As equally as important as the fighter is to protect the Russian units on West Russia from being destroyed on G1. If you lose them, you lose any chance of contesting Karelia/Belorussia. Germany may also stack Ukraine like you mentioned, cutting off 3 IPC to Russia (plus the 2 from Belorussia) and both sides get into a war of positions that doesn’t favor Russia (i.e. the Allies better get quickly to help).
