Very good essay. When the war ended on V-J Day, 95 divisions of all types, including the 6 Marine Divisions, had been mobilized and deployed overseas. None remained in the United States. Only one division, the 98th Infantry Division, had not seen combat and it was in Hawaii readying for the invasion of Japan.
The one complaint I have received about the essay is, “How about the Marine Corps?” I will say that of 19,000 Marines that landed on Guadalcanal, 8,500 as least once ended up in medical facilities with diseases, infections, and/or infestations of plants and bugs eating their flesh.
