United States Marine Corps

The  or USMC is the United States Military's amphibious infantry branch. The USMC appears as a faction in Call of Duty 4: Modern Warfare, Call of Duty: World at War, Call of Duty: Modern Warfare 2, Call of Duty: Black Ops and Call of Duty: Modern Warfare 3.

Call of Duty 4: Modern Warfare
The modern United States Marine Corps is portrayed in Call of Duty 4: Modern Warfare. In the beginning of the game, Marine Forces of the USMC 1st Force Reconnaissance are portrayed. The player takes the role of Paul Jackson, a Sergeant in 1st Force Recon and part of a Marine Task-Force to invade an unnamed Middle Eastern nation to capture Khaled Al-Asad, who took over the nation in a violent coup. In the Third day of the Invasion, Al-Asad detonated a Nuclear Device in his Capital City. This caused massive Marine casualties of 30,000 men, including Sgt. Paul Jackson. Later, the United States Marine Corps and the Special Air Service of Britain were involved in an operation to retake a Launch Control facility from Russian Ultranationalists and prevented ICBMs from striking the United States' Eastern Seaboard. Their escape was compromised, and in the ensuing chaos it is unknown if any of the SAS soldiers or Marines involved in the raid survived except for Sgt. 'Soap' MacTavish and Captain Price. It is quite interesting to note that there are several Pvt. ranked Marines depicted in the game. This is inaccurate as rank structure in the Force Recon is relatively higher than the regular Marine Corps. This is due to the length of time one spends in training before he can get into the unit, and is commensurate with the maturity and responsibility of being a Force Recon Marine. It would have been more accurate to use several Cpl. or even L.Cpl ranks but this must have averted for the public's familiarity with the rank structure.

Call of Duty: World at War
The USMC during World War II is portrayed in Call of Duty: World at War. In the beginning, C. Miller, who is part of a Marine Raider reconnaissance team is captured with his team mates on Makin Atoll by the Imperial Japanese Army. Almost a week later, another Marine Raider team led by Sergeant Sullivan and Corporal Roebuck comes to rescue him. After Miller and some other survivors are freed, the squad make their way through the island to destroy an ammunition deposit and eventually escape on boats. 2 years later, Sullivan, Roebuck and Miller are now part of the invasion of Peleliu among the 1st Marine Division. After two months of fighting on Peleliu, and losing Sullivan during the landing, "The Old Breed" head for Okinawa, where the final American versus Japanese land battle would take place.

The Marines also fought against Nazi Zombies in Nacht der Untoten and Verruckt. Tank Dempsey led the team of Marines to Verruckt to extract Group 935 scientist Peter and resulted in almost all of the team's death; only Dempsey survived.

Call of Duty: Modern Warfare 2
The release date of Call of Duty: Modern Warfare 2 (November 10) is the USMC's birthday. The Marines are not a playable faction, though they are mentioned at the end of "The Only Easy Day...Was Yesterday" and are seen as the player flies away. They secure the SAM sites and "mop up" what the task force left behind and secure the hostages (though their character models are only reused ones of the Rangers'). It is later revealed that General Shepherd, U.S. commander of armed forces in the Middle East, commanded the Marines during the attack against Al-Asad. Also during the level "Of Their Own Accord" numerous Marine CH-46 Sea Knights are seen throughout the level supporting the battle and extracting wounded. A CH-46 Sea Knight is at the extraction zone at the end of "Cliffhanger", and the men securing the landing zone use the Call of Duty 4 skins of the Force Recon. AV-8B Harriers and AH-1W Super Cobras (which are proprietary to the Marine Corps) can be seen and called in as a killstreak reward in multiplayer. There are U.S. Marine members in Task Force 141, most likely from MARSOC, Force Reconnaissance platoons, Reconnaissance Battalions, and Scout Sniper platoons.

Call of Duty: Modern Warfare: Mobilized
Marines are a playable faction in Call of Duty: Modern Warfare: Mobilized both in campaign mode and multiplayer.

Call of Duty: Black Ops
Marines appear in Call of Duty: Black Ops, in the missions "S.O.G.", "The Defector", "Crash Site", "Victor Charlie", "Payback" and "Redemption". Except for the mission "S.O.G." in which they wear the standard olive-drab uniforms of the time, they appear to be Marine Force Recon in the later missions as they wear tiger-stripe camouflage uniforms instead of the olive-drab uniform. Tank Dempsey, a Marine Raider, also reappears in Kino der Toten, Ascension, Shangri-La, Moon and in a easter egg in Call of the Dead. Mason and Woods are also former marines.

Call of Duty: Modern Warfare 3
The 2nd Marine Division are briefly shown as one of the special mission units in Call of Duty: Modern Warfare 3, in the mission briefing for "Black Tuesday". The Marines are fighting in the New York City area alongside the 75th Ranger Regiment. When the fight moves to Europe, Marines take part in the invasion of Hamburg, Germany in the mission "Goalpost". Marine infantry (character models are reused Rangers models from Call of Duty: Modern Warfare 2) and equipment such as V-22 Ospreys and M1A2 Abrams are used in the beach assault. In several missions V-22 Ospreys are used as support for Delta Force.

Trivia

 * In the earliest stages of the development of Call of Duty 4: Modern Warfare, the Marines used the same HUD icon in multiplayer as the Americans in Call of Duty 2.
 * As seen in C4 demo, USMC originally had a different faction icon.
 * The USMC multiplayer faction icon can be found in Call of Duty: Modern Warfare 2 files. This proves that USMC were originally going to be a playable faction, as the icon is different from the icon used in Call of Duty 4: Modern Warfare.
