The Claymore mine is a directional anti personnel mine developed for the United States Armed Forces. Its inventor Norman MacLeod named the mine after a large medieval Scottish sword. 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. The Claymore can also be victim activated by booby trapping it with a tripwire firing system for use in area denial operations.
