It isn’t historically accurate any more so than it is a combination of three things:
My knowledge of the general tactical situation in summer 1941
A 2 turn progression of the game from the OOB setup
Additional pieces added for flavor
Also, some pre-destined attacks, like pearl harbor, and the hunt of the bismark, because those are neat little historical tidbits:
- New Zeland can’t be emptied 100% with 1 tranport, so it always has a unit on it
- Soviet far eastern force is way stronger, but needed desperately in Moscow.
- UK navy isn’t in the crosshairs of the german navy, and reduced to near nothing on G1
- USA starts with a lot more manpower, to offset the cost of having to buy transports constantly
- Canada starts with more units to encourage transports to move back and forth from there
