The only difference between Global 1940 2nd Edition set up and Alpha+3 is that one UK infantry is removed from Egypt.
However, for Europe 1940 2nd Edition, that UK Infantry is retained since there won’t be 2 ANZAC infantry there.
Other minor changes include Korea being part of the whole Mongolia situation and that China cannot research Technology.
Europe 1940 and Pacific 1940 follow the exact same set up in Alpha+3…
Except, of course, no ANZAC in Europe 1940 and no Russia in Pacific 1940.
Europe 1940 and Pacific 1940 also have different USA NOs and an additional USSR NO for Europe.
