@Pacific:
I remember that I nuked North Korea (that nuke cost me 20 IPC’s IIRC) only to see my buddy smile and replentish all the infantry I killed on his next turn! I forgot about some dang rule that gives NK access to LOADS of infantry. What a waste of money that attack was.
At the end of the Soviet’s turn (presumably on the non-combat move phase; the rule is a little vague) if China is contributing any income to them, the soviet player may “move” up to 6 Chinese (i.e. neutral) infantry from Manchuria to North Korea. The rules go on to say that the infantry moved out of Manchuria are automatically replaced on the Soviet “place units” phase, and that Manchuria will always have he same number of Chinese infantry.
If Chinese support drops to where they are not sending income to the USSR, the rule says the Chinese infantry in North Korea are “returned to China” which sort of conflicts with the previous rule about there always being the same number of infantry in Manchuria. In my experience, when this happens, most players assumed the infantry in North Korea “spontaneously combusted.” I can’t recall there ever having been an “official” ruling from Imp Games on this point, but maybe there was and I just missed it.
