The M1 Garand (formally the United States Rifle, Caliber .30, M1) was the first semi-automatic rifle to be generally issued to the infantry in any nation. In 1936, it officially replaced the bolt-action Springfield M1903 rifle as the standard service rifle of the United States military (the M1903 retaining a valuable role as a sniper rifle), and was subsequently replaced by the select-fire M14 in 1957. However, the M1 continued to be used in large numbers until 1963, and to a lesser degree until 1966.
