Sniper rifles are classified as crew-served, as the term is used in the United States military. A sniper team (or sniper cell) consists of a combination of one or more "shooters" with force protection elements and support personnel: such as a "spotter" or a "flanker". Within the Table of Organization and Equipment for both the United States Army and the U.S. Marine Corps, the operator of the weapon has an assistant trained to fulfill multiple roles, in addition to being sniper-qualified in the operation of the weapon.
