|Tier 1 Perk|
- "Trip activated explosive mine."
- — Perk description
Claymore x2 is a first tier perk in Call of Duty 4: Modern Warfare that gives a player two trip-activated claymore mines that are manually planted on the ground by the player. When claymores are set up, two thin, short red beams indicate the presence of a claymore, as well as the direction the claymore is facing. A marker with the team's insignia will show above friendly claymores. Claymores cannot be activated by friendly players, neither can claymores kill friendly players directly. A claymore is activated when an enemy player moves into close proximity of the red beams on the front of a claymore. There will be a distinct "click" sound, followed by the claymore's detonation 0.83 seconds later. It is possible to activate enemy claymores without being killed (such as by running past the Claymore fast enough to get behind it before it detonates). An enemy claymore can be destroyed by shooting it. Claymores only explode 60 degrees in front of them and upwards. A claymore cannot do damage to someone who is below it, behind it or outside of the 60 degree cone.
Claymores are best placed so that the red lasers cannot be easily seen, such as in vegetation, a red-colored area (a place illuminated by fire), or around corners. The best example of a well-hidden claymore would be in the red grass near the fire on Bloc, near where Target B is in Search and Destroy.
Claymores are also often used by snipers to cover doorways for them while they snipe. If the intruder is not killed in the explosion, the sniper is alerted by the noise (or the display of a hitmarker to show damage dealt by the claymore.) and can often be ready to fight back.
One problem with claymores is that even if the enemy does not see the claymore and carries on walking, the claymore will click and have a 0.83 second delay before exploding, giving the enemy a chance to jump back and avoid it (unlike a Bouncing Betty in Call of Duty: World at War, which explodes with little notice for the enemy).
A good tactical acceptance is to place Claymores facing a car, standing in a narrow passage, for example at the north spawn-point at Crash. Red lasers are located towards car and it's hard to notice them, hard to pass without detonation, and explosion will blow up the car, giving much more damage.
If a player has Bomb Squad equipped, one can see enemy Claymores easily, allowing one to shoot them.
