Originating from the United States, the Claymore mine weighs 3.5 lbs (1.58kg). The dimensions of this anti-personnel mine is 216 by 38mm, with a height of 124mm.
The M18A1 Claymore is filled with 680g of C-4 and 700 steel balls of 3.17mm diameter. When detonated these metal balls will be blasted at a velocity of 2,684 mph (4,320 km/h); faster than an ordinary bullet. It has been in service since 1960 and was used in many wars, including the Vietnam War, Iraq War and Gulf War.
Many countries have their own licensed and unlicensed manufactures of the Claymore mine. Notably, the South Koreans have a smaller version (K440) of the mine that blast 770 fragments instead of 700 metal balls. The United States herself has also produced a smaller variant of the mine called the MM-1 Minimore for use by the Special Forces.
Interestingly, the average cost of the M18A1 Claymore mine costs $119 per unit to manufacture from 1993 (without including the cost of explosives).
