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.
Mameluke sword
Marine Corps history states that a sword of this type was presented to Marine First Lieutenant Presley O'Bannon by the Ottoman Empire viceroy, Prince Hamet, on December 8, 1805, during the First Barbary War, in Libya, as a gesture of respect and praise for the Marines' actions at the Battle of Derna (1805). Upon his return to the United States, the state of Virginia presented him with a silver-hilted sword featuring an eaglehead hilt and a curved blade modeled after the original Mameluke sword given to him by Hamet. Its blade is inscribed with his name and a commemoration of the Battle of Tripoli Harbor.
