The M18 Claymore series are directional antipersonnel mines developed during the 1950s. The M18A1 Claymore is the main production version and the most likely to be seen: it was adopted by the United States Military in 1960 and first used in Vietnam in 1966. Contrary to depictions in media which usually show it as rigged to a tripwire or proximity detonated, the M18A1 is almost always used in a command-detonated mode using the M57 "clacker" detonator (a small piezoelectric toggle generator based on an igniter developed by the US Navy for the "Tiny Tim" air-to-surface rocket) linked to the mine via a cable. Multiple mines can be daisychained to the same detonator. While they are not usually used in a self-detonated mode, it is possible to rig up systems to detonate the mine via other means: anything which can trigger a blasting cap will work.

The mine's payload is 700 1/8-inch (3.2mm) steel ball bearings encased in a resin matrix, set in front of a convex layer of C4 explosive that is normally triggered by a blasting cap. On detonation, the ball bearings are ejected in a 60-degree arc at around 4,000 feet per second (1,200 meters per second or Mach 3.6) with the force of the detonation distorting them to the point they resemble .22 caliber bullets. The mine's effective range is around 55 yards (50m), though fragments can travel up to 270 yards (250m). Because the plastic mine body is completely destroyed by the detonation, the Claymore also has a "backblast" danger zone of 52 feet (16m) in the remaining 300 degrees not part of the main blast. The "hump" on the top of the mine is an iron sight to allow the user to judge its area of effect when placing it, with the two "ears" on the side a pair of removable combination shipping plugs and priming adaptors which cover the two fuze wells: these can be rotated, and can either be used to route a cable through to an inserted blasting cap, or removed to insert non-standard detonators. Claymores are typically issued in an M7 bandolier ("Claymore bag") containing a printed instruction sheet, a mine, M6 electric blasting caps, the M57 detonator, a 100-foot (30m) M4 firing wire wrapped around a plastic spool, and an M40 circuit tester for function tests.

The original M18 was barely produced (only 10,000 were made, some of which made their way to Vietnam in 1961) and can be distinguished from the M18A1 by having straight stakes for legs rather than the fold-open scissor-legs of the M18A1, with stability provided by a third leg in the middle which extends out in front of the mine, and with the iron sight on top of the mine an optional accessory. It is not marked "FRONT TOWARD ENEMY." It is also internally different, using C-3 explosive instead of C4 and using steel cube projectiles instead of ball bearings. It was ineffective, having numerous reliability issues and a range of only 30 yards (27m). The battery-powered firing device issued with this variant and early M18A1s was notoriously unsafe to the point that FM 23-23 ("Antipersonnel Mine M18A1 And M18 (Claymore)") states that batteries should not be inserted into it unless the user is attempting to detonate whatever it is attached to.

The Claymore has been extensively copied by other powers with the Soviet MON-50 anti-personnel mine being the most numerous of these. The Soviets also produced the double-sized MON-90, and other widely-used copies include the Chinese Type 66 and Serbian MRUD. The US also produces the smaller MM-1 "Minimore" and the US military is currently testing a 2-pound variant as the "Mini-Multi-Purpose Infantry Munition" (M-MPIMS).

In a live-action production the mines are, obviously, never going to be live devices outside of stock footage. The mine casing often comes from an M68 Inert Training Kit: the mine in this kit, the M33, has no explosive or pyrotechnic filler, and is either blue, black, or green with a blue band. The kit also contains an M10 inert firing wire. In films, M33 mines can sometimes be recognised by the green paint flaking off or being scratched due to handling, revealing the original color below and / or the word "INERT" written on both edges of the rear face on some variants (for example in Predator). In both this movie and Commando the armorer appears to have ground off "M33" from the rear face, leaving only the words "BACK APERS MINE," though more recent films have either added the "M18A1" lettering or used reproduction M18A1 backplates.

The M18A1 Claymore and variants can be seen in the following films, television series, video games, and anime used by the following actors:

Video Games

Claymore mines in videogames are almost universally shown as proximity detonated, usually triggered by stepping inside their blast zone; as a result, their area of effect is generally unrealistically small. Proximity detonation is not a feature of the real mine, which is typically command detonated using a "clacker" triggering device. They also invariably only have any effect in their main 60 degree arc, without the 52-foot concussion and case fragment hazard zone in all directions.
