As for what to do on J2 and J3 in the India Crush,
Downloaded my maps first. (the first is the combat moves, the second is the NCM and builds after the battles rolling to odds).
J2
You will be very reactionary in this turn, but you will need to kill any potential blockers that can make it to sz38 or sz38. Or at least be in those sea zones with enough force that the Allies can’t force their way through. That is easily done since the entire Japanese fleet will be down there anyway.
If he tries to stand in Bur, Sze Yun, Mal or Shm, wipe them all out. Since 99% of your planes are in Kwa, and you have a loaded TT in sz42 and a tank in Phi, there is more than enough to take all 3. You want to minimize your plane casualties, so divide it up in a manner that you kill him in your 1st throw. Since you will have some ground units in Shm, Mal and Yun, those can use less planes.
If for some reason you can’t hit them all, then hit the UK forces, as China can’t help the UK at all.
You will then bring your 3 loaded TTs from Japan down to sz36 and build your naval and air base and put it in Kwa.
Again, NCM is very dependant on where the allies are. A DD blocking in sz16 is usually needed.
