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.
Uniforms of the United States Navy
Full Dress uniforms are worn for ceremonies such as changes of command, retirements, commissionings and decommissionings, funerals, weddings, or when otherwise appropriate. Full Dress is similar to Service Dress except that instead of ribbons, full-size medals are worn above the left breast pocket, with ribbons worn on the opposite side for decorations without corresponding medals. Swords or cutlasses are authorized for wear by officers and chief petty officers, and may be required for Lt. Commander and above.
