Unlike a conventional landmine, the Claymore mine is command-detonated and directional, being fired by a remote-control and shooting a pattern of metal balls into the kill zone like a shotgun. It is primarily used for ambushes and as an anti-infiltration device against enemy infantry.
This weapon was tested against the the Box Mine in eliminating a group of three targets. The box mine failed to trigger the pointman's 100G shock patch but still killed it with a potentially fatal leg amputation while the M18 Claymore killed all three targets through its shrapnel spray. The edge was given to the M18 Claymore for its higher lethality.
