i dont think china really had 15inf. more like 6-7. but those 6 or 7 inf wanted to attack manchuria, which had something like 3arm & 2inf. the US wanted to use their long range heavy bombers to blast the japs first, followed by the chinamen to take the IC. wasnt sure what the rule was on that ‘combined’ attack.
That’s still a lot of Chinamen. I’m lucky if I have 2 or 3…hehe. Seems a risky proposition to use your Heavy bombers, the Manchuria IC is useless to the allies. Depriving it to Japan could be usefull, and might be worth sacraficing a bomber. All depends on what else was going on.
