Despite the fact that it provides zero camouflage function, and is the least striking and visible of the camouflage patterns (it is almost invisible on some weapons on low light maps), Red Tiger is still a very popular camouflage pattern, mostly because of the fact that it signifies that the player has obtained 150 headshots with the weapon, which is regarded as a symbol of player skill by many (although some players simply use the Cage Match mode to unlock Red Tiger, somewhat negating its "status" symbol).
The Red Tiger Camouflage in Call of Duty 4's multiplayer Create-A-Class menu.
The Red Tiger camouflage features again in Call of Duty: Modern Warfare 2. It is unlocked by obtaining 150 headshots with the chosen weapon, (primary weapons only) and is the second to last weapon camouflage to be unlocked. As opposed to Call of Duty 4: Modern Warfare where the pattern was composed of pale, thinly colored red stripes against a predominant gray background, the variant in Modern Warfare 2 utilizes a more striking pattern that is reminiscent of the Tigerstripe camouflage used by US and South Vietnamese troops during the Vietnam War, along with a deeper red which makes the pattern far more visible and refined. It is the second to last unlocked finish, with Fall Camouflage being the last.
