[The NARA files account for those taken into the Army/Air Corp. There was a standing army in existance of several hundred thousand who don't show up in the file. There was a National guard of just under a million. NARA has a file on them, too. Then there was the Mavy, Marine Corps, Coast Guard and, maybe, the Merchant Marine who were accounted for elswhere.]
I guess I wasn't thinking.It did take the combined effort of all the different services.Our local Nat'l. Guard unit was mobilized in 1940 - took about a half dozen of my H.S. Sr. class mates.
The Navy played a role in about four landings in the European Theater: N. Africa, Cicily, Anzio and Normandie.What with the Island hopping strategy,in the Pacific we had one of those landings about every 3 or 4 months, 3 on New Guinea alone.in the 3 years I was with them theNavy hauled my outfit (3rd Bomb. Gp.) to 6 different destinations: Port Moresby, N.G.; Dobo Dura, N.G.; Nadzab, N.G.; Hollandia, N.G.; Leyte, P.I. and Mindoro, P.I.
I don't know if the Marines were used in the European Theater, but they played a major role in the Pacific; spearheading many of those landings.I believe the most costly were Guadalcanal and Tarawa.
The Merchant Marines maned all the supply ships needed to supply the war in the Pacific; and they took their share of casualties.In the Christmas convoy from Leyte to Mindoro in Dec. '44 the first ship hit by the Kamakazis was an ammunition Liberty Ship - no survivors.
I'm not sure where the Coast Guard operated, but you can bet they did their part.
