I’ve thought some more about the details of this strategy. Firstly, it is not advised against a G1 DOW. So if we proceed on the assumption there is no G1 DOW, I like these builds/moves:
place 2 inf in Stalingrad
move the 2 inf in Caucasus to Kazakhstan - China bound.
move a tank to Turkmenistan.
move a AA gun towards China
remaining 2 mecs + 1 tank + planes move towards China.
UK West India inf activates East Persia
That way you can still take Iraq with a G2/G3 DOW.
If there is no G2 DOW, move the Stalingrad inf + Turkmenistan tank to Caucasus and leave Persia for the UK. Take NW Persia USSR3 & Iraq USSR4.
With a G2 DOW, Turkmenistan tank activates Persia and Stalingrad inf proceed to the eastern front with Germany. Tac bomber positions to support the attack on Iraq USSR3.
Downside - are too many troops being stripped from the Eastern Front?
