Well, there IS a US Destroyer in the Pacific… it just starts out “on patrol” at the Panama Canal.
If we are going to be talking “should be’s” then where oh where is the Bismark? Yes, the “Germans” have the Vichy French fleet, and thus the BB in the Med, but where is the Bismark, Graf Spee, etc.? Surely they are not represented by one lonely DST in the Baltic…
I also have a few issues with the UK Indian Ocean fleets. A CARRIER off India? Nope, all of their AF in that area was land based.
New Guinea should be split, with the southern edge being British and have an INF and a FIG there. There should be no AC off India, but add a DST off South New Guinea.
And if you are going to add a UK sub somewhere in the Atlantic, then you need to account for the South Atlantic U-Boats with an additional German sub somewhere in SZ11, 12, 16 or 17.
