Back to the OP. One other point I’m coming to see is devastating is to land 4 ground units on Kwangsi J1. These units really make a big difference in being able to hold on to Yunnan. While you can’t get the TTs back to Japan J2 unless you combine a Naval base on Hainan or Kwangsi, the main game in Asia isn’t to get Japanese land units on Asia but to deny the Burma Rd. If you can do that, your one step on the way to Axis victory in the Pacific. One of the land units can come from Okinawa, two from Japan so you are only relocating one unit within Asia, the artillery from Manchuria, but in a very advantageous way.
