The M18 was 9.25-inch (235 mm) long and 3.27-inch (83 mm) high, held in a plastic case with three folding spike legs on the bottom. The screenplay for Rambo was written by Art Monterastelli and Sylvester Stallone. Later a Philadelphia company, Molded Plastic Insulation Company, took over the manufacture of the firing device for the first large-scale production run producing a plastic device.[1]. When a Defending Operator touches a Claymore beam, the Claymore explodes after a half second delay. The mine was triggered from a safe position, preferably to the side and rear. The case has the words "FRONT TOWARD ENEMY" embossed on the front of the mine. The M18A1 Claymore mine has a horizontally convex gray-green plastic case (inert training versions are light blue or green with a light blue band).

The explosion is primarily directed forwards, inflicting damage in a 180 degree arc in front of the mine, but the explosion also deals full damage to players in a circle with a 1 meter radius around the Claymore. The initial versions of the mine used two pairs of wire legs produced from number 9 wire. [7] Given the requirements of weight and fragment density, approximately 700 fragments were needed, with the ability to aim the mine with an accuracy of around two feet (0.61 m) at the center of the target zone. Firstly, the hardened steel balls spalled into fragments when hit by the shock of the explosion; the fragments were neither aerodynamic enough nor large enough to perform effectively. Remove the dust cover from the firing device and firing wire. This was found to be undesirable for a number of reasons. It is used primarily in ambushes and as an anti-infiltration device against enemy infantry. It was too large to be a practical infantry weapon and was relatively ineffective, with a maximum effective range of only 20 to 30 yards (about 20 to 30 meters).[1]. Type of Directional fragmentation anti-personnel mine. | Content ©www.MilitaryFactory.com. [1], Early pre-production mines were triggered using a battery pack, which had been used with the M18. It is packed in a Claymore bag with inert M10 simulated detonator cap wire, an M57 "clacker" firing control, and an M40 circuit test kit. On both sides of the sight are fuse wells set at 45 degrees. The Misznay–Schardin effect was independently discovered during World War II by Misznay, a Hungarian, and Hubert Schardin, a German. Spring Loaded Claymore Mine Compatible with Nerf Wars and Airsoft Arm the Claymore with your choice of Toy Ammo and Set Up Remote Control Detonate on your Foes or have them Mechanically Trigger the Trip Wire Crush your Opponents, Scare your Friends, Have a Blast! With the 16 meter danger area of a Claymore, the backblast of the explosive can cause concussion injuries of personnel, even when they are under cover. MacLeod's case collapsed when photographs of the German Trenchmine prototype were produced as evidence of prior art.[1]. When the mines are daisy-chained together, one firing device can detonate several mines. When the M18A1 is detonated, the explosion drives the matrix forward, out of the mine at a velocity of 1,200 m/s (3,937 ft/s),[1] at the same time breaking it into individual fragments. Optimum range is 50 to 100 meters. Please direct all other inquiries to militaryfactory AT gmail.com. M18 Claymore 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. We do not sell any of the items showcased on this site. The mine is detonated as the enemy personnel approaches the killing zone.

They did not spall from the shock of the explosive, but deformed into a useful aerodynamic shape similar to a .22 rimfire projectile. [5] It lacked the later version's iconic "FRONT TOWARD ENEMY" marking. Schardin also spent time researching a "trench mine" that used a directional fragmentation effect.
