    The CheyTac Intervention is a sniper weapons system developed by the American firm of CheyTac Associates based out of Arco, Idaho. The Intervention is classified as an "anti-material rifle" intended to counter light or "soft" armored threats and other targets of interest at extreme ranges utilizing a large-caliber cartridge developed by CheyTac itself. Anti-material rifles are used to a high degree by military forces the world over to give sharpshooters the ability to target and disable key components of enemy vehicles including vision ports, sensors, track linkages, engine blocks and the like. The Intervention is sold as a complete weapons package to include the rifle, case, optics, ammunition supply, replacement barrels and various accessories and is considered one of the most accurate long range shooting platforms anywhere in the world with effective ranges out to 2,000 meters. Under ideal testing conditions, the Intervention has shown its accuracy out to 2,200 meters including group shots (bullets repeatedly hitting the same spot on a target). The Intervention has gone on to set a world record for best grouping at distance (2,122 meters).

    While many of today's anti-material rifles utilize the widely-accepted .50 BMG cartridge, CheyTac developed their .408 for use in their Intervention. Per CheyTac's own wording, the .408 is a bridge cartridge between the 338 Lapua and .50 BMG rounds currently in widespread use. The .408 cartridge was developed utilizing computer software and is produced by Lost River Ballistic Technologies. The round is said to compete favorably with the .50 BMG in the anti-material role and collectively weigh much less, allowing the operator to carry more ammunition. General comparisons between the .50 BMG versus the Intervention's .408 cartridge put the .50 BMG ahead in its initial muzzle velocity (11,200lbs versus 7,700lbs) though, as Cheytac explains, their .408 retains much more of its energy beyond the 700 yard mark which leads to its highly-touted long-range accuracy.

    All told, the Intervention is a rather conventionally-designed sniper system. The major working internal components are held within the receiver which contains the firing action as well as the manually-actuated bolt-action lever (turn-bolt design). The lever hangs down to the right side of the gun body. There is a forend assembly over the barrel base and the barrel extends a distance out from the gun body proper. The barrel is further capped by an integrated muzzle brake and can accept a suppressor. Atop the receiver there is a Picatinny style rail system for the mounting of optics and accessories. An ergonomic carrying handle is attached under the forend ahead of the receiver. The .408 ammunition is fed via a spring-loaded, seven-shot, detachable box magazine ("repeater" production models only) inserted ahead of the pistol grip and trigger unit. The magazine itself is wide with vertical ribbing and inserts directly under the forward portion of the receiver. An ejection port is identified to the right side of the gun body, above the magazine feed. The pistol grip is of a rugged and stout design, ergonomically finished and conveniently angled rearwards with an enlarged base. The trigger is well-protected by a low-set guard as well as the pistol grip aft and the magazine feed ahead. The shoulder stock is another ergonomically refined element, hollow in its design and supported by two extension rods emanating from the receiver sides. This allows the operator to wholly adjust the extension of the shoulder support as needed. A collapsible bipod is adjustable and fitted to the forend assembly. An adjustable monopod is seen at the base of the shoulder stock. The Intervention weighs in at 31lbs without optics and sports a running length of 53 inches on full extension.
