hope you like this Update, next update will be the Invasion of the USA! We give also the order of 10 new CL and maybe even more forces. The troops we want to use for the USA are 50 MAR divisions + German and italian Units, 20 Naval Bomber, 15 CL, 3 CV, 8 INT. No idea of it will be possible but i hope. if anybody got Ideas how i can do that please let me now!
By now the USA should have a highly mechanized/armor force so marines with ART support will be in real trouble. To invade the US in 1942 you only need up to 8 divisions of marines (4MAR+1ENG) to capture WDC. Then land your HA+MEC+SPART+TD+ENG divisions or if you don't have the IC you could get away with "only" HA+INF+ART+AT+ENG (or even MOT+MOT+SPART+TD+ENG). With anything less than these expect to lose allot of men, especially if you do not control the skies.
EDIT: since you already have 50 divisions of marines with ART(?) try this combination, because they will perform much better once they reach land: MAR+MAR+ART+ARM+TD (or AT saves IC). But use only 4MAR+1ENG to capture ports.
BTW nice AAR and goodluck with your invasion plans.
