This list contains weapons that are classified as crew-served, as the term is used in the United States military.
While the general understanding is that crew-served weapons require more than one person to operate them, there are important exceptions in the case of both squad automatic weapons (SAW) and sniper rifles. Within the table of organization and equipment for both the United States Army and the U.S. Marine Corps, these two classes of weapons are understood to be crew-served, as the operator of the weapon has an assistant, who carries additional ammunition and associated equipment, acts as a spotter, and is also fully qualified in the operation of the weapon.
