United States Marine Corps/Black Ops

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 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.

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.
