I think the Chinese capacity to game such things with plenty of cover & backup and CERTAINLY MASSIVE NUMBERS is well beyond what the average--even military man--might imagine.
Game all they want, they have to be able to execute, impossible without air support. I can imagine alot, I can't imagine the Chinks sending over a massive army undetected, but if detected, being able to sustain them in the field with a 6500 mile LOC. Not in this world.
