answer:My great uncle Vince got his in WWI, gassed in the trenches. My father got his as a Marine on a spit of sand called Eniwetok in the South Pacific, 1943. Japanese shrapnel to the forehead. He woke up in a line of bodies with a chaplin giving Extreme Unction to the body next to him. Patched up in a hospital in San Diego, shipped off to Boca Raton for “Tropicalization Training” as if he needed it after a year in the Pacific. He was on a troop train headed for San Diego for further shipment to the invasion of Japan when the bomb was dropped. My brother got his during his first tour in Nam as an Army combat medic. Took a round in the ass upon arrival at a hot LZ. He did a second tour with the Riverines in the Delta.
