Machine Gun
A machine gun is usually a rifle-caliber or larger, crew-served, belt-fed automatic firearm. Traditionally one rifle-caliber machine gun is deployed per platoon-sized (8 person) unit. Larger machine guns, such as the .50 caliber Browning M2 are used in vehicle- or tripod-mounted applications.
