The problem for the Japanese Falcon is exactly where are they getting their air support from? They have no carriers in the area. Their nearest airfields are on Formosa and at the edge of the range of their aircraft. They have no ability to real time coordinate air strikes on tactical ground targets. And, lastly, have little ability to carry out such strikes. Note that throughout the war both the IJN and IJA air forces pretty much never put in any sort of close air support operations anywhere. So, I doubt that air attack would be much of a problem.
