Nickname for a five round, bolt action rifle made at Springfield Armory also known as an '03 (named so because of the model year of the rifle, the Model 1903 Springfield Rifle). Fired .30 caliber rounds. Was the main
weapon for infantry during World
War I. Usage of the rifle continued into early World
War II, until it was completely replaced by the semi automatic, eight round M1 Garand. Afterwards, the Springfield mainly saw usage as a markman's rifle in the U.S Armed Forces and
served as the standard American sniper rifle during WWII, Korea, and Vietnam.
