United States Marine Corps noncommissioned officer's sword
The Marine Corps noncommissioned officer's sword is a sword worn by noncommissioned officers (NCOs) and staff noncommissioned officers (SNCOs) of the United States Marine Corps. The NCO sword was adopted in 1859 and is patterned after the United States Army's foot officers' sword of 1850. The M1859 NCO sword continues service today as the Marine Corps drill and ceremonial sword. The sword's use is restricted by regulation to ceremonial occasions by an NCO or Staff NCO in command of troops under arms or at weddings and wedding receptions where at least one of those being married is in uniform and has the rank of Corporal or higher.
List of crew-served weapons of the U.S. Armed Forces
While the general understanding is that crew-serve weapons, unlike individual service weapons, require more than one person to operate them, there are important exceptions in the case of both squad automatic weapons (SAW) and special application rifles (SAR). 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-serve, as the operator of the weapon (identified as a marksman or as a SAW gunner) 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.
