Russ, I think that most of the new tanks (or turret upgrades) will go to the East front.

In the South, the Luftwaffe is unable to perform what you describe. Moreover, the French will still rely on ground observers and picket ships in addition to radar. And this is probably also true for Greeks and Yougoslavs. But the Americans (and this is also true in a lesser extent for the British) relied more on radar and could be surprised like this. Yes, they were in OTL : operation Bodenplatte, in Jan 1945 (en.wikipedia.org/wiki/Ope...odenplatte ).

The lessons and material given by the Japanese will probably not be in use before the beginning of 1943, at least.
