Donald W. Duncan

Master Sergeant Donald Walter "Don" Duncan (March 18, 1930 - March 25, 2009) was a U.S. Army Special Forces soldier who served during the Vietnam War, helping to establish the guerrilla infiltration force Project DELTA there. Following his return to the United States, Duncan became outspoken in his opposition to the conflict and became one of the leading public figures in opposition to the war. Duncan is best remembered as the military editor of the radical monthly magazine, Ramparts, during the Vietnam conflict and for his testimony to the 1967 Russell Tribunal detailing American war crimes in Vietnam.

Donald Walter Duncan, known to his friends as "Don," was born in Toronto on March 18, 1930, but was a US citizen.

Duncan was drafted into the U.S. Army in December 1956, serving as a non-commissioned officer in Germany in the field of operations and intelligence.

Duncan transferred to U.S. Army Special Forces (the "Green Berets") in the first part of 1961, where he continued to work in the field of operations and intelligence. During this interval Duncan received additional training in communications, weapons, and demolitions. Duncan served as an instructor at the United States Army Special Warfare School at Fort Bragg, North Carolina for a year and a half, teaching courses to Special Forces members on intelligence tactics and interrogation methods.

Duncan was deployed in Vietnam in March 1964, serving in a variety of capacities with the 5th Special Forces Group and Project DELTA, which he helped to organize. In addition to briefing and debriefing incoming and outgoing soldiers in the theater, Duncan directly participated in 8-member intelligence and "hunter-killer" teams.
