how the axis wins (my prefered stratigy);
G1; (either save the german battleship and buy carrier to fake sealion, or save all the money to fake it, or just buy 9 inf (or some combo if inf/art) with germany. take finland, france, land ftrs in italy, take yugoslavia
I1, do whatever use one pz to take bulgaria, build 1 mech (or one ftr)
G2; build 18 (ish) mechs and move inf to poland
I2, move inf + mech from turn1 to rumania, if russia have left east poland open, delcare war on russia and take it. (build 1 mech and do whatever in med)
G3 move stack to east poland, if italy holds it, you dont need to declare war, otherwise declare war; build 6-10 mech and start building some planes (to use against Wallies, ftrs and bombers are best)
I3, depends on where russia stands, if they stand in belo, w ukraine is open and germany is strong enough to stand in ukraine, when they can land ftrs there and move their stack, then take ukraine, otherwise move all italian infs to bessarabia
g4, last round to produce mechs against russia, probably not many needed, need to build some infs for paris, some mechs for w germany and some ftrs/bombers to fight allies, move stack in east to w ukraine or besarabia (preferably w ukraine).
I4 stack to ukraine, (russia should not have enough to hold ukraine and bryansk against germany, so ukraine should be empty)
g5 move stack to ukraine built ftrs + bombers + landtroops for west
I5 at this point you should have 2 pz 1-2 bombers 4 inf and 2-4 mechs + 1-2 ftrs that can canopen on the east front, russia should not be capable of stopping you from taking rostov without committing at lesst 10 inf to it, which he should not be able to afford so take rostow, build 3 mechs in ukraine (if you can afford it, italy might be in danger at this point)
G6 move to rostov, land all the ftrs you can afford to have here, and use as many mechs /pz/bombers you need to hit and hold stalingrad + cauc if possible.
R6 ususally have to retreat to moscow, since italians can canopen 10-15 units, and there are 2 paths for germany to hit moscow with the 35 + mechs/pz that germany have.
then hit middle east, while building arts in stalingrad, arts/infs in leningrad. at this point you will often have higher production that the allies.
if japan did india crush in round 3, USA could not land in europe before US4, if you have been good and build enough planes, and enough defence in west, us should not be able to really take anything except for north africa at this point. japanese india crush is very good for this stratigy, because germany have 16 IPC in NOS in the middle east+ cauc, and the landunits in india are the best ones for taking middle east + cauc back. (middle east + cauc + stalingrad =24 IPC for germany)
Japan can alternatlivly hit russia, to make them have less landunits, this is maybe preferable if your stratigy is to attack moscow, instead of the middle east.
