Blue Tiger Camouflage

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

- Camouflage description

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 added to it.

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, 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 returns as a camouflage option, only instead of being a blue and black pattern, it is now two shades of blue, one darker and one lighter with a similar pattern. However, it is hard to see on some weapons (like the UMP45) because of the limited camouflage on the gun. It is unlocked after 75 headshots in multiplayer.

Like Red Tiger Camouflage, the Call of Duty: Modern Warfare 2 version is more pronounced than the version from its predecessor.

Call of Duty: Black Ops II
The Blue Tiger Camouflage returns again in Call of Duty: Black Ops II.

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 camouflage.
 * In Call of Duty: Modern Warfare 2, when the player achieves Level 50 in multiplayer, they will acquire a title saying Maj. with the Blue Tiger background.
