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).
Commandos: Behind Enemy Lines
Each commando that the player gets to control has a different set of abilities and equipment that they can use to deal with enemies and help them complete their missions - the Green Beret is able to move barrels, climb rough surfaces, use a lure to distract enemies, and can kill soldiers with a knife; the Marine can dive underwater, use a harpoon gun, can kill enemies with a knife, and is the only one who can pilot ships and boats; the Driver is the only one who can drive vehicles and operate tanks and mounted guns, and is one of two commandos who can treat the injuries of his comrades; the Sapper is the only one capable of using grenades and handling explosives, but can also cut through wire fences and set up traps; the Sniper is the only one who can use a sniper rifle to take out targets, and the second commando who can treat his comrades injuries with a first aid kit; the Spy can wear enemy uniforms, distract soldiers when disguised as an officer, and can kill enemies with a lethal injection. In addition to their abilities, all commandos carry a handgun that they can use as a last resort to defend themselves. The game's emphasis is towards stealth and carefully planned tactics rather than gun battles, as the commandos will not survive for long if shot at.
