Intervention (weapon)

The CheyTac Intervention is an American-made bolt action sniper rifle designed by CheyTac LLC. for long range soft target interdiction. The intervention system refers to a package including a range finder, computer, optics, and the rifle itself, called the M200. It is a bolt action rifle using the proprietary .408 Cheytac round, intended to fall in between the .50 BMG and the .338 Lapua, both popular long-range rounds. The rifle is also designed to be accurate even when equipped with a suppressor for over 2000 meters.

In-Game
The Intervention is available on multiplayer from level 1, and judging by the multiplayer videos, acts much like the M40A3; both guns, when combined with Stopping Power, usually result in one-shot kills.

Trivia

 * This weapon has a specially made suppressor called the PGRS-1.
 * The .408 Cheytac is considered a "Wildcat" cartridge, that is, one that is not officially recognized or readily supported by other weapons.
 * It was probably put into the game, just like the SPAS-12, to have a popular cinematic gun.
 * On a more ironic note, this gun is not used by the armed forces of Iraq/Saudi Arabia, Russia, America, or Britain. It is actually used by Poland and Turkey, both of whose military forces are not in Call of Duty: Modern Warfare 2. However, since it is available to civilian shooters, insurgents and special forces alike could acquire them by legal means.
 * The Intervention has a unique and easily recognizable gunshot. It is different from the sounds of any other sniper in the Call of Duty series so far.
 * The .408 round the Cheytac Intervention is chambered for in this game is said to be the world's most accurate rifle round.
 * The Intervention's reload is off by nearly half it's full reloading time, making it easy to Reload Cancel.
