Marine Camouflage

Marine Camouflage is a secret camouflage exclusive to the Wii version of Call of Duty: Modern Warfare 3, but is also available on consoles and PC through modifying the weapon files. It is unlocked after prestiging once, along with the Winter Camouflage (on the Wii only).

It appears to be very similar to the Woodland MARPAT camouflage used by United States Marine Corps, hence the name in game. Interestingly, it is also visible on the title "Gen." on the other platforms, which is the second-to-last rank-based title awarded prior to prestiging.
