Claymore

The claymore is an anti-personnel mine featured in Call of Duty 4: Modern Warfare, Call of Duty: Modern Warfare 2 and Call of Duty: Black Ops.

Call of Duty 4: Modern Warfare
In Call of Duty 4: Modern Warfare, the claymore is first seen in the level "Blackout" when Gaz orders Soap to place them in front of the guard house and draw the guards' attention.

Usually, the player starts out with claymores in their inventory. Claymores are mainly used in "One Shot, One Kill" after the player killed Zakhaev when Captain MacMillan orders the player to plant claymores around the perimeter in order to kill enemies before they get close enough to snipe them.

In multiplayer, the claymore is unlocked at level 23 and can be used to defend a position from enemy assault. Claymores are mostly used when a player stays in one area and want to protect themselves. In the beginning of a match, the player begins with only two claymores. As the claymore takes up the first slot, the RPG-7 and special grenades can't be used. The amount of damage delivered by the claymore increases with the Sonic Boom perk, as it increases the damage of all explosive weapons damage.

Call of Duty: Modern Warfare 2
The claymore makes a return in Call of Duty: Modern Warfare 2, however it is available as equipment instead of as a perk. Players only receive one in the beginning of a match, however, but can resupply them with the Scavenger and One Man Army perks.

If a player plants a claymore, stands in front of it and shoots it the claymore will damage and kill the player. If an enemy shoots it, it will damage its owner and any of the owner's teammates, but not the shooter's allies. Also, a player can never trigger their own or allied claymores, but if they are standing too close (particularly in Hardcore modes) when an enemy triggers it, it will hurt or kill them as well.

Claymores are often also used as an early-warning system that enemies are coming. They are now also temporarily disabled by enemy stun grenades and flash grenades detonating nearby, including the original planter of the mine. In Hardcore, friendly stuns and flashbangs also cause the same effect. Deactivated Claymores will spark and smoke a little. After about 5 seconds the claymore will reactivate and will explode as normal when triggered. Additionally, Claymores are immediately placed when the equipment button is pressed and released, instead of being drawn with one button press and placed with the primary fire button, as in Call of Duty 4: Modern Warfare.

Campaign
Claymores only appear in the last section of "The Defector". They are primarily used to defend against the waves of NVA forces at this portion of the game. They can be found on top of a wooden box. The player can carry up to five claymores before having to pick up more. Once those are placed, more can be collected from the box, the total number being 20 claymores.

Multiplayer
Claymores are featured in Call of Duty: Black Ops. Claymores can be carried around as in Call of Duty 4 and are placed with the fire button. They can also be picked up and moved after being placed. They differ from previous iterations of the claymore, as they do not "click" when the wires are tripped, instead they make a quick "beep beep" sound. The sound is so quiet that it will usually be drowned out by gunfire and explosions. They are unlocked at level 4 when Create-A-Class is unlocked and cost, making them the most expensive equipment in the game, along with the Motion Sensor.

An enemy RC-XD will trigger a claymore, destroying both or if the player were to boost while driving the RC-XD it will pass the claymore and be unaffected but the Claymore will go off. Attack Dogs will also trigger claymores.

Zombies
Claymores are usable on the maps Kino der Toten, "Five", Ascension and Call of the Dead where they cost 1000 points to buy off the wall. The player receives 2 when first bought, and they are restored after every round at a rate of 2, like grenades. Claymores come in handy in the higher levels due to their very high power, and they are often used to help a group of players camp, as players that are reloading can use the claymores to protect them until they have finished reloading. Like with Grenades and Monkey Bombs, getting a Max Ammo will replenish the amount of claymores the player has.

Claymores in Kino der Toten are located in the front stage area right behind the power switch.

Claymores in "Five" are located in the Science Labs in the Room with the Pig.

Claymores in Ascension are located one door away from Stamin-Up, near the Lunar Lander.

Claymores in Call of the Dead are located in the room directly behind Double Tap Root Beer.

Tactics

 * In Kino der Toten, they are good to use as choke-points as zombies will be forced into one area. They are also good to make Crawlers that are running behind the player.
 * In Five, the best place to put claymores are in the Panic Room, when the door opens large numbers of zombies will be coming at the player and claymores will make most of them into crawlers or just kill them. Other choke points are the Starting and Elevator-hallway doors, the stairs leading to the balcony in the DEFCON level, and doors in the Science Labs.
 * Also, claymores can be hoarded by placing the two received at the start of each round against a wall. Zombies cannot set them off and they will not disappear between waves. The player who set the claymores can pick them back up at a later time as he/she needs them.
 * If the player has a claymore placed and the player dies, it will disappear once the player respawns, so if the player died from an enemy that is near the player's claymore, the player may want to watch the KillCam to let the Claymore have a chance of a revenge kill. But in the Search and Destroy game mode the claymore will not disappear after the player has been killed so that it allows for a kill after the player has died.
 * Scrambler Pro delays claymore detonation when they are tripped, allowing the player to easily escape from the claymore before it detonates. The Lightweight and/or Marathon perks also allow players to sprint past claymores before they detonate. Players using the SitRep perk can easily detect claymores and can find a way to destroy, disable or evade them. Some tactically-aware players can pinpoint enemy camping locations using the equipment locations. However, that doesn't always work.
 * If up against players with Marathon or Lightweight the player find his claymores not detonating in time for a kill, a good method of countering this is to place Claymores away from the enemy. So instead of placing it towards a doorway, place it at a corner facing away from it. This is because the explosion radius is larger than the trip radius, and in this configuration it is tripped immediately and the rushing player stays in the explosive radius for a longer period of time.
 * An exception to the tip above: keen players will knife the claymore, detonating it harmlessly. The explosion doesn't set of alarms, but can kill nearby players if they are close enough (other than the person disarming it).

Tips

 * A Claymore cannot be detonated or disabled by teammates, even if they shoot it. In Hardcore mode though, it is possible to destroy friendly claymores.
 * In Afghan, Claymores can easily look like rocks or debris, making them highly beneficial. On the other hand they do not camouflage well in snowy, arctic levels, such as Derail.
 * The trigger lasers for the claymore are actually misleading, as the real trigger range is slightly wider than the actual lasers.
 * Claymores can be placed while planting the bomb in such game modes as Search and Destroy and Demolition.
 * A Claymore can be placed facing a thin wall as a way to find enemy players as the lasers will stick out through the wall and will still detonate and cause some damage.
 * A Claymore explosion/triggering can be heard going off by the planter no matter how far away they are from where they set it in Call of Duty 4: Modern Warfare.
 * Claymores do not have a ceiling on their explosions - they can kill a player who is floors above them if the surfaces allow it. For this reason, be careful trying to flank a claymore while walking over catwalks and openings.
 * Claymores can be placed facing enemy Tactical Insertions in order to kill the spawning enemy.
 * If the player's claymore is stunned by a flash/stun grenade, he can still manually detonate it by shooting it or using another explosive.
 * A good unused tactic for claymores is, to put one right in front of the entrance and placing one a bit further behind it, as many players will not see the second one, and the claymores would be triggered at the same time. Most will run behind the first claymore to avoid it but will be caught off guard for the second one.
 * Another tactic is to "body bomb" where a claymore is placed over a corpse, effectively concealing it. This is useful for killing an enemy, if the player knows where a dropped bomb is in Search & Destroy or Sabotage.
 * Using Bomb Squad, SitRep, Scrambler Pro, Hacker, or Flak Jacket is an effective way to avoid being killed by a claymore.
 * In Nazi Zombies, if a player died and has a claymore planted, they can pick up the claymore without having to buy claymores again. If the player holds on to the claymore, they get two more every round. The player can buy an additional two claymores from the wall as well.

Trivia

 * In Modern Warfare 2 the player can only have 2 claymores deployed, meaning if he places 2 in front of a door and if he places a 3rd one the first Claymore will explode.
 * In the Call of Duty 4: Modern Warfare level "One Shot, One Kill", there is a Claymore planted in front of a door that cannot be destroyed.
 * The sound of the Claymore clicking before it detonates uses the same audio file as the mines that would click before detonating as the player walked over them in Call of Duty and Call of Duty 2.
 * When looking at a Claymore in Call of Duty Black Ops, it says on the back "BACK M18 A1 APERS MINE" and on the front it says, "FRONT TOWARD ENEMY".
 * There is a death quote which includes the Claymore; "If you can't remember, the claymore is pointed towards you".
 * In Modern Warfare 2, after the player plants a bomb, setting a Claymore will bring back up the yellow "briefcase" used to plant the bomb after the Claymore is deployed. This is a glitch.
 * Call of Duty: World at War's Bouncing Betty fills a similar role as the Claymore.
 * If the player puts a claymore in front of an enemy player standing still, it will not explode. The player can spin, reload, or even throw a grenade without the claymore detonating. The only thing that detonates claymores is attempting to move and jumping.
 * In the Special Ops level Armor Piercing, the player can refill their Claymore mines after getting out of the map. The Claymores are located next to the M14 EBR.
 * As said in localization files, the Claymore originally had a detonator and required time to plant but dropped as it would be extremely similar to C4.
 * In the map Terminal, there's a glitch that occurs if a player places a claymore on the emergency slide of the airplane, it will bounce off and often plant its self far away.
 * In the map Carnival there is a glitch that occurs if a player plants a claymore on the top of the clowns head, on the Fun House. The claymore will bounce off and plant itself within 100 ft.
 * The Black Ops Claymore has a much shorter detonation time than the Modern Warfare 2 iteration. The "click" noise is also significantly quieter.
 * In Black Ops there is a glitch that if a claymore is planted while a host change occurs, after it detonates the lasers remain. This also happens if a player plants their claymore, but then picks it up again.
 * There is a glitch in multiplayer Kino der Toten concerning claymores. If Player 2 places a claymore and Player 1 were to run past or move in front of it the claymore will go off but Player 1 will take no damage.
 * There is now a pick up icon in Black Ops for claymore. The pick up icon is colored.
 * If the player crawls behind a Claymore and knifes it, it will explode harmlessly.
 * The pickup icon for Claymore in Call of Duty 4 is the killfeed icon for an exploding car kill.
 * Players often jump on tables to place their claymores rather than placing claymores on the ground primarily because it becomes harder for enemy players to see the claymore and when detonated, the explosion is at a much taller elevation, damaging an enemy player's lower body and upper body.
 * When activated, the claymore will make a single clicking sound, before detonating (.83 sec. delay). A claymore can be spotted by the red lasers it produces or with the Bomb Squad perk. Defeating a claymore can be done by throwing a grenade at its position or shooting the mine. Although not harmful to the person setting it down when detonated if said person is standing behind it, it will kill or seriously injure a player if it is detonated with them in front of it.
 * In multiplayer, one can only place two claymores at a time; if a third is placed, the first will explode. If two Claymores are placed so that the laser detectors cross, both will explode.
 * In multiplayer, if a player is holding a claymore and they are killed, the claymore will fall from their hands and plant itself, which may cause the attacker to run into it and activate it.
 * If a player stands at the edge of an area above the ground and places a Claymore, it will be placed on the ground below as long as there is no room. This works for all equipment.
