• The M18 Claymore, a directional
  fragmentation mine, is 8-1/2 inches long, 1-3/8
  inches wide, 3-1/4 inches high, and weighs 3-1/2
  pounds. The mine contains 700 steel spheres (10.5
  grains) and 1-1/2 pound layer of composition C-4
  explosive and is initiated by a No. 2 electric
  blasting cap. The M18 command-detonated mine may
  be employed with obstacles or on the approaches,
  forward edges, flanks and rear edges of
  protective minefields as close-in protection
  against a dismounted Infantry attack.

• The M18A1 mine is primarily a defensive
  weapon. It may be employed to a limited extent in
  certain phases of offensive operations. The M18A1
  has the same basic capabilities as antipersonnel
  mines and can be used in most situations where
  other types of antipersonnel mines are employed.
  In addition, the M18A1 has the capability of
  being sighted directionally to provide
  fragmentation over a specific area and does not
  necessarily rely upon chance detonation by the
  enemy. The M18A1 is adaptable for covering the
  ranges between maximum hand grenade throwing
  distance and the minimum safe distance of mortar
  and artillery supporting fires
