Some Garands were still being used by the United States into the Vietnam War in 1963; despite the M14's official adoption in 1958, it was not until 1965 that the changeover from the M1 Garand was fully completed in the active-duty component of the Army (with the exception of the sniper variants, which were introduced in World War II and saw action in Korea and Vietnam). The Garand remained in service with the Army Reserve, Army National Guard and the Navy into the early 1970s. The South Korean Army was using M1 Garands in the Vietnam War as late as 1966.
