OK I think I might just have something viable for dealing with those stupid Siberians. With this one the idea is to use threat of overwhelming force to coerce the Bolsheviks into turtling while you drive the SS panzer army up North and then block the enemy horde at Novosibersk. I’m gonna call this one the Novosiberia Blitz.
G1 build 6 mech, 1 armor. Take France and Yugo, lose artillery before mechs in France. Move 3 tanks and every unit in range to Poland, including the 2 infantry from Denmark with the transport.
R1 Siberians in Buryatia
J1 Japanese take Chahar and all units from Manchuria and Korea go into Amur
G2 build 10 tanks in Germany, invade Baltic States and Karelia, mobile units from France head East. Planes in Poland
R2 Novgorod forces run screaming to Archangel. Siberians in Yakut
J2 take Suiyuyan. Amur force chasing the Siberians West
G3 All from Baltic states and Karelia to Novgorod (total is something like 25inf, 3 art, 4 armor, 6 mech, 3 AA). Second panzer army goes to Baltic states (10 new tanks plus up to 6 tanks and 4 mechs from Paris, plus air units).
R3 Russians evacuate Archangel to Smolensk and/or Vologda. Siberians in Yenisey
J3 Land a million airplanes in Suiyuyan and build airbase
G4 All to Archangel; planes in Novgorod.
R4 Japan can airstrike either Vologda or Smolensk and land in Archangel, thus allowing the Germans to blitz into Moscow. If Soviet forces are split to defend both, then the Germans can kill either force easily, perhaps both of them. Only good option is to pull back in to Moscow. Siberians in Timguska.
J4 Clear anything in Vologda, if there is anything, but there probably wont be anything.
G5 tanks/mechs blitz to Novosibersk; pull inf/art back to Novgorod
R5 attack SS panzer army with infantry @1? It’s 20 tanks plus some 6-10 mechs
J5 If Siberians do not attack Germans, kill them with Amur force and air.
G6 Stalingrad and Caucasus
Note how at any point in this little parade the Russians could attack the Germans, but losses would be so terrible that all they really CAN do is pull back. If they stand in the way they will be crushed by this big tank force with air support and loads of infantry/mechs.
