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).
Uniforms of the United States Marine Corps
The buttons on the dress and service coats are reminiscent of Marine insignia prior to the adoption of the Eagle, Globe, and Anchor. The quatrefoil—the cross-shaped braid worn atop an officer's cover—is a distinguishing part of the Marine officer's uniform. The design is of French origin, and is a tradition from the pre-Civil War era when officers wore a rope cross on their caps to allow sharpshooters high in the rigging of a sailing ship to identify his allies in a battle. Enlisted Marines wear service stripes on the cuff of the dress and service coats, each stripe denoting four years of service as a Marine. The standing collar of the dress coat is reminiscent of the uniform that earned Marines the nickname "Leatherneck".
