M1 Garand rifle
The basic infantry weapon of U.S. forces in the Second World War, as well as one still used in less advanced militaries as well as in sporting derivatives, the M-1 Garand rifle was a clip-fed semi-automatic rifle, firing a .30-06 full-power rifle cartridge. 
It was replaced briefly by the M14 rifle, also firing a full-power NATO 7.62mm cartridge, which, in turn, has been replaced by the M16 family of assault rifles firing the intermediate power 5.56mm round. Today, most commonly issued U.S. rifle is the M-4 carbine variant of the M16 rifle. Both the M14 and M16 were capable of full-automatic, although the latest versions fire either in semi-automatic mode, or a burst of three shots fired automatically.
Principles of operation
Even standard M1s were capable of quite accurate fire, and troops were trained to exploit its capabilities.
The M-1C and M-1D are highly accurate versions optimized for use by snipers.
