I might as well continue with round 2-5 that concerns the eastern front.
AH2:
Buy: Only units for the Italien front
Attack: Sevastopol with Romania with 13 inf, 4 art plus plane (bought r1) from Vienna (lets say you lost 3 inf taking Romania r1), Assume you lose 2 inf taking Sevastopol
Attack: Ukraine with 1 Inf (Do not comit everything from Galica since it will be counter-attacked from Polen and Moscow if you do)
Move: 4 inf and 2 art from Vienna to Galicia (the units you bought r1)
R2(25 IPC+1):
Buy: 8 inf, save 2 IPC
Move: 15 inf and 6 art from Polen to Belarus
Move: 1 inf from Tatarstan to Moscow
Move: 1 inf from Karelia to Moscow
(Total in Moscow: 34 inf and 5 art)
G2:
Buy: Inf and art, everything towards the western front,
Move: 31 inf,d 9 art,1 plane from Silicia and Prussia into Polen
AH3:
Attack: 1 inf from Ukraine to Tatarstan
Move: 9 inf and 4 art from Sevastopol to Ukraine (Leave 2 inf in defence from Britain so they cant just take it with 1 unti)
Move: 18 inf and 6 art from Galicia to Ukraine (28 inf and 10 art + 1 plane total in Ukraine)
R3(15+2 IPC):
Buy: 5 inf
Attack: Ukraine with 15 inf and 6 art from Belarus and 34 inf and 5 art from Moscow; Kills appr. 24 units and loss: 18 units. AH: 4 inf, 10 art and 1 plane left, Russia: 31 inf and 11 art left
Total in Moscow: 5 inf
G3:
Attack: Livonia with 2 inf from Polen
Attack: Belarus with 29 inf, 9 art and 1 plane from Polen
AH4:
Nothing on the eastern front
R4(11 IPC):
Buy: 3 inf
Move: 30 inf and 11 art from Ukraine to Moscow (leave 1 unit in Ukraine so AH cant reinforce Moscow)
Total in Moscow: 38 inf and 11 art
G4:
Attack: Moscow with 31 inf, 9 art and 1 plane (You will lose appr. 25 units and kill 18), Germany: 7 inf, 9 art and 1 plane left, Russia: 20 inf and 11 art left
AH5:
Attack: Ukraine from Ukraine
R5:
Counterattack Moscow: Kill appr.: 14 units (Axis total: 17 Units), not enough to clear. Russian Revolution!
This is very tight though, and with some luck RR wont happen!
Britain would liberate atleast Sevastopol R3/R4, which means the way south will be goon for the Axis.
