Well not having played the Spring 42’ version I’ll base my theory on the original version as the US you go last, which is a good thing, in the respect that you get to react, which is much better then deciding on an action, you can judge where and when your needed and act accordingly, if Britain and Russia have Germany on the ropes concentrate mostly on the Pacific, if the they need help concentrate mostly on the atlantic.
now when Japan takes out my carrier in pearl I’ll build another and stock it with the fighters from the mainland with the california BB and transport as tag alongs, with those 3 and a transport or two more you have some island hoppers to invade the Japanese held islands with.
and if you can get Britain and Russia to kick Japan off the Asian land mass Japan will be done with.
