Is the basic rule that every British unit counts as “Europe” as soon as it is on the European board and treated accordingly (may not enter Russia), whereas every UK Unit in Asia is treated as Pacific and may enter Russia, regardless of where it started or was built or anything?
UK units are just UK units, no matter where they are or where they came from. The distinction here is which map the Soviet territories are on, not the source of the units moving into them.
What if my Russian airplane lands on a carrier off the Indian cost, and that carrier then tries to move to Africa?
The carrier may not leave the Pacific map until either the Soviet fighter leaves it or the USSR is at war in Europe.
And what about an ANZAC fighter entering the European board? Is it allowed to fly to Russia’s European side?
No.
Thanks alot!
