You don't need an army vet, you need information. Simply having "been there" doesn't necessarily make one an expert (or even a reliable source).
Private Amos Hicks enlisted well before Pearl Harbor, having over five years service at the time of his death on the twenty-ninth day of operations on Okinawa. He was serving with the 165th Infantry, 27th Infantry Division when he died.
He's buried at the National Memorial Cemetery of the Pacific in Honolulu, Hawaii. You can obtain a little info on his gravesite by accessing the American Battle Monuments Commission (ABMC) website at < http://www.americanwardead.com/searchww.htmhttp://www.americanwardead.com/searchww.htm>. When you arrive there, enter "Hicks Amos" (no puncuation) and follow the directions from there. Some of the information given is inaccurate but I can fix that.
I'm sending you a couple addresses and a toll-free number.
