When I was at military school(Allen Academy, Bryan,TX) many moons ago, we were required to memorize the nomenclature of the M-1 Garand, as that's what we were issued for the year. I'll never forget:
"An M-1 is a gas operated, clip fed, semi-automatic, shoulder fired weapon"
We were issued an FM 23-5 and sure enough, it's in there too:
"The U.S. rifle caliber .30, M1, (fig. 1) is an air-cooled, gas-operated,
clip-fed, and semiautomatic shoulder weapon. This means that the air cools the barrel; that the power to cock the rifle and chamber the succeeding round comes from the expanding gas of the round fired previously; that it is loaded by inserting a metal clip (containing a maximum of eight rounds) into the receiver; and that the rifle fires one round each time the trigger is pulled."
