They adopted simple peep sights, which were later replaced by a knife blade sight. A bandolier is issued for the carrying of M18 Claymores and also contains an instruction sheet. The M18a1 Claymore can be attached to a trip wire or set off by a timer. In total the mine weighed about 2.43-pound (1.10 kg), and could be fitted with an optional peep sight for aiming. A layer of tinfoil was added between the fragmentation matrix and the explosive. The mine was barely more than a prototype and was not considered a "reliable casualty producer"; like the Phoenix it had an effective range of only 90 feet (27 m). The mine was triggered from a safe position, preferably to the side and rear. MacLeod designed a weapon called the T-48; broadly similar to the final M18A1, it lacked a number of the design details that made the M18A1 effective. Examples include former Soviet Union models MON-50, MON-90, MON-100, and MON-200, as well as MRUD (Serbia), MAPED F1 (France), and Mini MS-803 (South Africa). A bandolier is issued for the carrying of M18 Claymores and also contains an instruction sheet. Optimum range is 50 to 100 meters. It is not clear if the United States Picatinny Arsenal took the concept from the Canadian weapon and asked Norman MacLeod to develop it, or if he developed the design independently and presented it to them. 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. 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. It does not contain an explosive or pyrotechnic filler of any kind. The Claymore mine is typically deployed in one of three modes: Controlled, Uncontrolled, or Time-delayed. 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. Type of Directional fragmentation anti-personnel mine. [1], Minor modifications were made to the mine during its service. 9. The case has the words \"Front Toward Enemy\" embossed on the front of the mine. The M18 directional fragmentation anti-personnel mine, developed by Cardoen of Chile, contains 626 grams of explosives, surrounded by 607 AP fragmentation units providing a 60 degree arc of fire, with a 50-250 metre lethal range. The mine can be detonated by any mechanism that activates the blasting cap. Bill Kincheloe came up with the idea of using a "Tiny Tim" toggle generator, of the type used with a number of Navy rockets. [5] It lacked the later version's iconic "FRONT TOWARD ENEMY" marking. Detonation is initiated by a No 2 electric blasting cap. It comes with all the components of a real Claymore kit packed in an M7 bandolier. Can you complete this Mine/Explosion themed typing challenge where typing a wrong letter ends the quiz? The M18a1 claymore mine is based around a 1.5lb slab of plastic explosives packed behind 700 steel balls. Its lethality out to 50 metres arrives in the form of 650 steel balls and it is activated by remote control or trip wire. The team at Aerojet were given access to all previous research into directional mines, including the M18 and the Phoenix, as well as German research. [1], Following the massed Chinese attacks during the Korean War, Canada and the United States began to develop projects to counter them. Its inventor, Norman MacLeod, named the mine after a large medieval Scottish sword. All written content, illustrations, and photography are unique to this website (unless where indicated) and not for reuse/reproduction in any form. The shape was developed through experimentation to deliver the optimum distribution of fragments at 50 m (55 yd) range. These performed poorly for two reasons. It was awarded a pre-production contract for 1,000 M18A1 Claymores, designated T-48E1 during testing. It has the surface space of an average smartphone and includes a Picatinny rail for camera, laser, or other attachments. The M18 is a command detonated mine that is directional. 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! There are field-expedient methods of detonating the mine by tripwire, or by a timer, but these are rarely used. Military investigators determined that the mine was deliberately placed in the window and detonated to kill Esposito and Allen. Using a homemade chronograph, the engineers clocked the balls at 3,775 feet (1,151 m) per second. An M40 circuit test set is packed in each case of six mines. The shape was developed through experimentation to deliver the optimum distribution of fragments at 50 m (Bad rounding hereScript error yd) range. 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. A simple open sight on the top surface allows for aiming the mine. Anti-personnel mines are used in a similar manner to anti-tank mines, in static "mine fields" along national borders or in defense of strategic positions as described in greater detail in the land mine article. It is also used against unarmored vehicles. At Aerojet in the early 1950s, Guy C. Throner had independently come up with a design for a Claymore-like mine. Internally the mine contains a layer of C-4 explosive behind a matrix of about seven hundred 1⁄8-inch-diameter (3.2 mm) steel balls set into an epoxy resin. It is used primarily in ambushes and as an anti-infiltration device against enemy infantry. The mine is detonated as the enemy personnel approaches the killing zone. In fact, so long as the operator can find a way to actuate the blasting caps, the M18 will trigger. A ferrite choke was added to prevent RF signals and lightning from triggering the mine.[1]. [1] Originally an aluminum box was used to hold the generator. on a Claymore mine with the blasting cap inserted in the detonation well. PADMINE is an anti-personnel directional fragmentation mine produced by the United Kingdom, similar to the Claymore in cosmetic design with two swivelling legs, inserted into soft-ground. They are not reported as mines; however, the emplacing unit must ensure that the mines are removed, detonated, or turned over to a relieving unit. A number of licensed and unlicensed copies of the mine have been produced. The M-MPIMS is designed to be more controllable than the Claymore with less collateral damage, using an insensitive munitions explosive that is poured rather than packed for more uniform distribution results in more consistent blast pattern. This was determined experimentally by Bledsoe, through a large number of test firings. Controlled Mode (also known as Command Detonation) The mine is detonated by the operator as the forward edge of the enemy approaches a point within the killing zone (20 to 30 meters (65 to 100 ft)) where maximum casualties can be inflicted. 8/21/2019 Around 1952 Norman MacLeod, at his company the Calord Corporation, began working on a small directional mine for use by infantry. 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 was planted in the ground, using its three sharp legs, and aimed in the direction of enemy approach; at that point, it was fitted with an electrical blasting cap. The case has the words "FRONT TOWARD ENEMY" embossed on the front of the mine. The 100-foot (30 m) M4 electric firing wire on a green plastic spool is provided in each bandolier. He named his antipersonnel mine the claymore, after the two-handed sword wielded by his Scottish ancestors. Rambo was preceded by First Blood (1982) (1982), Rambo: First Blood Part II (1985) (1985), and Rambo III (1988) (1988). The M18A1 Claymore is a directional anti-personnel mine developed for the United States Armed Forces. Two pairs of scissor legs attached to the bottom support the mine and allow it to be aimed vertically. The development project completed, the Aerojet team sent the project back to Picatinny. He worked with Don Kennedy and the two men submitted a 30-page proposal in response to Picatinny's RFP. Rear-safety distance has been decreased to 15 m (49 ft) and shelf life has been increased to 25 years.[8]. Later when production was ramped up, the design was changed to flat steel scissor, folding-type legs. An electrical blasting cap for triggering the mine was inserted through a small hole in the side. The M57 device (known as a "clacker") was held in the hand and featured a trigger that was squeezed a number of times by the Claymore operator to convert mechanical energy into electrical energy using an armature and magnets. In early 2015, the U.S. Army began testing a smaller version of the Claymore called the Mini-Multi-Purpose Infantry Munition (M-MPIMS). The device weighed 5 pounds and shot 700 steel cubes 40 feet. The steel balls are projected in a 60° fan-shaped pattern that is 6.5 feet (2.0 m) high and 50 m (55 yd) wide at a range of 50 m (55 yd). We do not sell any of the items showcased on this site. When detonated, C-4 rapidly decomposes to release nitrogen, water and carbon oxides as well as other gases. Detonation can only be initiated by a shockwave, such as when a detonator inserted into it is fired. The firing device creates an electrical charge that fires the blasting cap placed inside the mine. One of the first improvements was to replace the steel cubes with 7⁄32-inch (5.6 mm) hardened 52100 alloy ball bearings. [1], A second problem was the curvature of the mine. A simple open sight on the top surface allows for aiming the mine. It was first used in Vietnam in the spring or early summer 1966. In the Vietnam War, the mine was used by the United States Army with effect against NVA (North Vietnamese Army) and VC (Viet Cong) forces along commonly used jungle trails during ambush missions.
