This is a list of weapons served individually by the United States armed forces . While the general understanding is that crew-served weapons require more than one person to operate them, there are important exceptions in the case for both squad automatic weapons (SAW) and sniper rifles . Within the Table of Organization and Equipment for both the United States Army and the United States Marine Corps , these two classes of weapons are considered as crew-served; 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. These weapons are listed under the List of crew-served weapons of the U.S. armed forces .
