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).
M27 Infantry Automatic Rifle
In early 2017, Marine Corps Commandant Gen. Robert Neller said he wanted to equip every "0311" rifleman with an M27 IAR. Because of that, the Marine Corps issued a request in early 2017 for 11,000 M27 IARs from H&K. While talking about the Corps' request, Chris Woodburn, deputy of the Maneuver Branch, Fires and Maneuver Integration at Marine Corps Combat Development Command, said "The new order will replace all M4s in every infantry squad with an M27, except for the squad leader." He also stated that the change includes infantry training battalions. The timeline for funding was planned for fiscal years 2019 and 2020, with the Corps acquiring some of the rifles in fiscal year 2018. As of August 2017, officials have stated that "riflemen are the top priority," but that the M27 "will be in the hands of combat engineers and light armored reconnaissance battalion scouts next." The Corps later issued a pre-solicitation notice for the M27. "The new pre-solicitation notice of 50,184 [M27s]," said Woodburn, "is [meant] to up the production capacity that H&K must be able to meet as the sole-source provider [of the M27], should the Marines decide to order more in the future." At SHOT Show 2018, the Marine Corps announced that the deal with H&K to produce 11,000 M27s for the Marine Corps had been finalized and that the M27 IAR would be adopted as the standard issue service rifle of the Marine Corps infantry, replacing the M4A1.
