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).
Inter-service awards and decorations of the United States military
The Medal of Honor, originally a Navy award, is now technically an inter-service award, is issued in different versions for each branch of military service. There are presently three versions of the decoration in existence for the Army, Navy, and Air Force. Marines receive the Navy version of the Medal of Honor while a Coast Guard version, which exists in theory, has never been bestowed (the one Coast Guard recipient of the Medal of Honor received the Navy version).
