Culture of the United States Marine Corps
Two styles of swords are worn by Marines. The Marine Corps officers' sword is a Mameluke Sword, similar to the Persian shamshir presented to Lt. Presley O'Bannon after the Battle of Derna during the First Barbary War. After its adoption in 1825 and initial distribution in 1826, Mameluke Swords have been worn by Marine officers ever since, except during the period 1859–1875, when they were required to wear the Army's Model 1850-foot officers' sword. Upon returning to the traditional sword, many officers gave their Army swords to their senior noncommissioned officer, creating the basis for the NCO sword. Generally, Marines are the only branch where enlisted members regularly carry a sword (the Army authorizes platoon and first sergeants to carry a Model 1840 sword during some ceremonies, while the Chief of Naval Operations authorized Chief Petty Officers and above to carry an optional ceremonial cutlass with dress uniforms in 2010).
Mameluke sword
Perhaps due to the Marines' distinguished record during this campaign, including the capture of the Tripolitan city of Derna after a long and dangerous desert march, Marine Corps Commandant Archibald Henderson adopted the Mameluke sword in 1825 for wear by Marine officers. After initial distribution in 1826, Mameluke swords have been worn except for the years 1859–1875 (when Marine officers were required to wear the U.S. Model 1850 Army foot officers' sword), and a brief period when swords were suspended during World War II. Since that time, Mameluke swords have been worn by Marine officers in a continuing tradition to the present day.
