The British Army looked at the M1 as a possible replacement for its bolt-action Lee–Enfield No.1 Mk III, but it was rejected when rigorous testing suggested that it was an unreliable weapon in muddy conditions. However, surplus M1 rifles were provided as foreign aid to American allies, including South Korea, West Germany, Italy, Japan, Denmark, Greece, Turkey, Iran, South Vietnam, the Philippines, etc. Most Garands shipped to allied nations were predominantly manufactured by International Harvester Corporation during the period of 1953–56, and second from Springfield Armory from all periods.
