Combat veterans like Bob Yeargan did not have time to worry about being gay when they were in the field. They and their buddies were much more worried about survival. Bob’s two tours of duty, first as a platoon leader and later as a company commander, reveal that combat leadership is not the exclusive purview of heterosexual officers. Yeargan went on to have a twenty-year career in the Army, retiring as a Lieutenant Colonel, working in the Pentagon. (Photo courtesy of Bob Yeargan.)
Robert G. Yeargan served in the US Army, commanding a unit of the 2nd Battalion, 35th Infantry Regiment, 25th Infantry Division during his tour in Vietnam.
Listen to an interview with Yeargan as part of the Library of Congress Veterans History Project. A complete transcript of the audio is also available.
