The M14 was developed to take the place of 7 different weapons systems; Enfield M1917 rifle, Thompson submachine gun, Springfield M1903 rifle, M1 rifle, M1 Carbine, M3 "Grease Gun" and M1918 Browning Automatic Rifle (BAR). It was thought that in this manner the M14 could simplify the logistical requirements of the troops by limiting the types of ammunition and parts needed to be supplied. It proved to be an impossible task to replace all seven as the cartridge was too powerful for the submachine gun role and the weapon was too light to serve as a light machine gun replacement for the BAR. (The M60 machine gun better served this specific task.)
