A crew-served (crew-serve or crew service) weapon is any weapon system that requires a crew of two or more individuals performing the same or separate tasks to run at maximum operational efficiency, as opposed to an individual-service weapon, which only requires one person to run at maximum operational efficiently. The weight and bulk of the system often also necessitates multiple personnel for transportation.
Crew-served weapons operated by infantry include high-precision/special application rifles, anti-materiel rifles, medium machine guns, heavy machine guns, automatic grenade launchers, mortars, anti-tank guns, anti-aircraft guns, recoilless rifles, shoulder-launched missile weapons, and static anti-tank and anti-aircraft missiles.
