TAR-21

The TAR-21 is a weapon featured in Call of Duty: Modern Warfare 2. It is powerful, but has a large amount of recoil when fired for an extended period of time.

Singleplayer
In the campaign, it is used heavily by the Russian military in the United States. It is available in all missons involving Russian Ultranationalists and the Brazilian Militia. In the Singleplayer Campaign and Special ops, this weapon is always seen with optics attached. In multiplayer, the TAR 21 uses rail modular sights. This is inaccurate because it does not possess built-in iron sights; the Tavor relies on rail-mounted optics.

Multiplayer
This weapon is unlocked at Level 20 (Sergeant First Class I). The TAR-21 carries 30-round magazines, deals 40-30 damage per shot and fires at 750 RPM, making it one of the highest damage-output weapons in the game. The weapon also possesses moderate recoil and is somewhat inaccurate making it difficult to use in the hands of an unskilled player at long ranges without short, controlled bursts of fire, especially with the use of an ACOG Scope.

The TAR-21 also possesses a unique tinted Red Dot Sight called the MARS Sight, which offers a slightly smaller, circular viewing space versus standard Red Dot attachments on other weapons. One of the advantages of this sight is that when using Bling with a Heartbeat Sensor, the Sensor is still visible while aiming down the sights. However, many players dislike the MARS sight due to its smaller size than a normal Red Dot Sight, and the fact that it reflects the in-game light, sometimes making it difficult to aim through. Because of this, many players will choose to use the Holographic Sight after unlocking it, as it is larger than the MARS sight, has a thinner frame, and does not glare as much while reflecting light. When the TAR-21 has the red dot sight, the dot will not disappear in an EMP.

Although the TAR-21's recoil makes it somewhat difficult to use at longer ranges (though this can be mostly negated with controlled bursts), its high damage per second makes it extremely effective at close and medium range. The TAR-21 is one of the only assault rifles that will be competitive with SMGs at close range. Due to these traits, this gun can be a very effective stealth/ambush weapon if used with a Silencer and Heartbeat Sensor.

In Hardcore mode, the TAR-21 is capable of a one shot kill without Stopping Power, unless firing through cover or at a player using Painkiller. Combined with an ACOG sight and lightly depressing the trigger to fire a single round can make this a very good anti-sniper, long distance support weapon, or if you simply want to snipe without a Ghillie suit. The same effect can be achieved with a Thermal Scope.

Trivia

 * The TAR-21 has a Mars Sight, however in Spec Ops it can be found with the normal Red Dot Sight.
 * When aiming down the MARS sight, if heartbeat sensor is attached also, it is still easily viewable
 * The empty reload animation is slightly different if the heartbeat sensor is attached
 * When the grenade launcher is equipped and the player is prone, the iron sights have the writings "Intensity Fire"
 * TAR-21 stands force Tavor Automatic Rifle - 21st century
 * Its unknown why the Ultranationals use the TAR-21 when it's mainly used by Israeli Defense Force "IDA"
 * The singleplayer campaign and Spec Ops of Modern Warfare 2 are the only places where the player can see the TAR-21 with the actual Red Dot Sight instead of the Mars Sight acting as the Red Dot Sight.
