Agreed and seconded.
I tend to look at '39 like this: if it doesn’t specifically say we can do something then we can’t, or we refer to the latest Axis and Allies Global rules to fill in the gaps.
EG a country cannot do something “special” like spawn infantry in territories without factories or without their capital unless explicitly outlined in the rules. Otherwise, they just get treated as any other country.
I don’t think in this case (or many others) we’ll get a rule RE print out on this issue as the focus seems to be on '36. I also vaguely recall tiger stating 7.2 is all she wrote.
These days, when tigerman makes a ruling I tend to scribble it in my rulebook.
