Nguyen Tan Hoa, 55, sits outside his guesthouse near Da Nang, Vietnam. Hoa was 10 when U.S. Marines from a Combined Action Platoon moved into his village during the Vietnam War. For the next three years, he spent most of his time with the Marines and still refers to himself proudly as one of them. "Whatever they got, I got," he says. "We shared everything." When Saigon fell to North Vietnamese forces in 1975, "I really felt like I was the last G.I. in Vietnam," he says. Aug. 10, 2012.
