Blue Tiger Camouflage

Blue Tiger Camouflage is a fictitious type of weapon camouflage in Call of Duty 4: Modern Warfare and Call of Duty: Modern Warfare 2.

While there are blue-hued camouflage patterns in real life, none are identical to the Modern Warfare series' Blue Tiger. The pattern was briefly considered by the United States Air Force, but was unpopular, and was dropped before the production phase.

Call of Duty 4: Modern Warfare
It is achieved by obtaining 75 headshots with a specific weapon, or 50 headshots for the W1200 and M1014. It has a pattern much like Woodland and Desert, except it has a black and blue shade.

Some players prefer Blue Tiger to Red Tiger because it is more noticeable and striking in all lighting (Red Tiger is almost invisible on some weapons on low light maps like Wet Work). Also, unlike Red Tiger, it actually can provide some camouflage function on maps like Wet Work and Vacant, which feature an abundance of blue hues.

Call of Duty: Modern Warfare 2
In Call of Duty: Modern Warfare 2 Blue Tiger is still a camouflage option, only instead of being blue and black it is now blue, with a darker shade of blue behind. This version is more similar to real-life Russian MVD camouflage.

Like Red Tiger Camouflage, the Call of Duty: Modern Warfare 2 version is more pronounced than the version from its predecessor, although there are little to no maps where it functions as an efficient camouflage. It can be unlocked after 75 headshots in multiplayer.

Trivia

 * In Call of Duty 4: Modern Warfare, when a player has every camouflage available for weapons that cannot obtain the Golden camouflage, Blue Tiger will be listed at the bottom. This is strange as it is not the final unlockable camo.
