Two pairs of scissor legs attached to the bottom support the mine and allow it to be aimed vertically. A simple open sight on the top surface allows for aiming the mine. The case has the words "FRONT TOWARD ENEMY" embossed on the front of the mine. The shape was developed through experimentation to deliver the optimum distribution of fragments at 50 m (55 yd) range. The M18A1 Claymore mine has a horizontally convex gray-green plastic case (inert training versions are light blue or green with a light blue band). Examples include former Soviet Union models MON-50, MON-90, MON-100, and MON-200, as well as MRUD (Serbia), MAPED F1 (France), and Mini MS-803 (South Africa). Many countries have developed and used mines like the Claymore. It is also used against unarmored vehicles. It is used primarily in ambushes and as an anti-infiltration device against enemy infantry. The Claymore fires steel balls out to about 100 m (110 yd) within a 60° arc in front of the device. The Claymore can also be victim-activated by booby-trapping it with a tripwire firing system for use in area denial operations. Unlike a conventional land mine, the Claymore is command-detonated and directional, meaning it is fired by remote-control and shoots a wide pattern of metal balls into the kill zone. Its inventor, Norman MacLeod, named the mine after a large medieval Scottish sword.

The Claymore mine is a directional anti-personnel mine developed for the United States Armed Forces.
