#1: Can Russia produce out of Germany? Or because their capital is gone, they no longer can produce anywhere?
You can’t purchase units if you don’t hold your capital.
@cocotheflyingnut:
#2:If Russia is taken over first, and then Russia takes out Germany, what happens to the money Russia would take from Germany? Does it go to the bank?
The USSR still gets the IPCs, but it can’t spend them until its capital is liberated.
@cocotheflyingnut:
#3: Does Caucasus become Japans? Does Japan have to put units in Caucasus for it to become theirs, or will it always be Germany’s unless Russia takes it back, and Japan takes it from them?
It will remain under German control until captured by an Allied power. Japan can’t take it from Germany.
@cocotheflyingnut:
#4: If Russia was taken over from Germany, but Russia takes Germany, and you have Japanese units also in Russia, who has ownership of Russia, and who, if anyone, is allowed to produce there?
Germany controls Russia until it is liberated by an Allied power. Germany can’t mobilize units there, since its capital is in enemy hands. Japan can’t mobilize units there, since it doesn’t control the territory. So, no one is allowed to use the IC until the situation changes (either Russia or Germany is liberated).
