M18A1 Claymore

The M18A1 Claymore is a directional anti-personnel mine developed for the United States Armed Forces. Its inventor, Norman MacLeod, named the mine after a large Scottish medieval sword. Unlike a conventional land mine, the Claymore is command-detonated and directional, meaning it is fired by remote-control and shoots a pattern of metal balls into the kill zone like a shotgun. The Claymore can also be victim-activated by booby-trapping it with a tripwire firing system for use in area denial operations.

The Claymore fires steel balls, out to about 100 m (110 yd) within a 60° arc in front of the device. It is used primarily in ambushes and as an anti-infiltration device against enemy infantry. It is also used against unarmored vehicles.

The Claymore uses two Cone templates side by side to indicate the killzone. Anyone within this area takes full damage. Anyone under cover in a 180-degree arc behind the Claymore out to 6" must make a Spirit roll or be Shaken due to blowback. Anyone who rolls a one on this roll is hit for 2d6 damage.
