The Green Berets were an American country and folk band active in the late 1960s, renowned for their patriotic themes. Their music style was characterized by a blend of country, folk, and military music, reflecting the socio-political climate of their era. The band is best known for their hit single "The Ballad of the Green Berets," a song written by Staff Sgt. Barry Sadler, a member of the U.S. Army Special Forces, which topped the Billboard Hot 100 chart in 1966. Their work, particularly this song, played a significant role in shaping the public's perception of the Vietnam War.
