He named his antipersonnel mine the claymore, after the two-handed sword wielded by his Scottish ancestors. The M18A1 Claymore mine with the M57 firing device and M4 electric blasting cap assembly. Fire the mine. , Kincheloe immediately suggested using softer 1⁄8-inch (3.2 mm) steel "gingle" balls, which were used in the foundry process. In comparison, the other anti-personnel weapons of the Vietnam War available to the US Army was the M67 fragmentation hand grenade, this having a kill-zone of up to 16.5 feet (though lobbed distance was limited to the thrower's arm ability), and the M79 single-shot grenade launcher, a pinpointed weapon sending a 40mm high-explosive (HE) grenade upwards of 1,149 feet down range - though these were similarly limited with a kill range of about 20 feet. 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. Controlled detonation may be accomplished by use of either an electrical or non-electrical firing system. Using a homemade chronograph, the engineers clocked the balls at 3,775 feet (1,151 m) per second.  These fragments are moderately effective up to a range of 100 m (110 yd), with a hit probability of around 10% on a prone man-sized 1.3-square-foot (0.12 m2) target. Their appearance is similar to the Claymore mine.. 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).. Test your knowledge on this just for fun quiz and compare your score to others. The M18A1 Claymore is a directional anti-personnel mine used by the U.S. military.Its inventor, Norman MacLeod, named the mine after a large Scottish medieval sword.  June 26 : The third highest ranking Sri Lankan military officer, Major General Parami Kulatunga was wounded in an attack by LTTE and died after being taken to the hospital. 4 x 6" spike legs are attached to the bottom of the M18 Claymore system to allow the mine to be easily secured into soft grounds. 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.. The weapon and all its accessories are carried in an M7 bandolier ("Claymore bag"). Please direct all other inquiries to militaryfactory AT gmail.com. 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. A number of licensed and unlicensed copies of the mine have been produced. An M40 circuit test set is packed in each case of six mines. Military investigators determined that the mine was deliberately placed in the window and detonated to kill Esposito and Allen. Rambo is the fourth movie in the Rambo series, which is based on First Blood, a 1972 novel by Canadian-American novelist David Morrell. The device weighed 5 pounds and shot 700 steel cubes 40 feet. A simple open sight on the top surface allows for aiming the mine. 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. The fragments can travel up to 250 m (270 yd). The sighting for the device was originally intended to be a cheap pentaprism device, which would allow the user to look down from above and see the sight picture.  Originally an aluminum box was used to hold the generator. 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. Italy produces the DAF M6 and DAF M7 directional fragmentation mines, weighing 18 and 10 kilograms respectively, with trip wire or remote control detonation. The mine is detonated as the enemy personnel approaches the killing zone. “Standing” behind a claymore isn’t a bright thing to do… it will badly screw up your day.

Throner had independently come up with a design for a Claymore-like mine. This slightly improves the fragment velocity, and protects the steel fragments from the corrosive explosive. Around 1952 Norman MacLeod, at his company the Calord Corporation, began working on a small directional mine for use by infantry. Internally the mine consisted of a layer of 12-ounce (340 g) of C-3 explosive (the forerunner of C-4 explosive) in front of which was laid an array of 0.25-inch (6.4 mm) steel cubes. When a sheet of explosive detonates in contact with a heavy backing surface (for example, a metal plate), the resulting blast is primarily directed away from the surface in a single direction. When the mines are daisy-chained together, one firing device can detonate several mines. Can you complete this Mine/Explosion themed typing challenge where typing a wrong letter ends the quiz? 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. The case has the words "FRONT TOWARD ENEMY" embossed on the front of the mine. , By the spring of 1956, Aerojet had a near-final design. Optimum range is 50 to 100 meters. Through Picatinny, the United States Army accepted the weapon into service as the M18 Claymore and approximately 10,000 were produced. Many countries have developed and used mines like the Claymore. The Picatinny criteria for the weapon were as follows: The requirement for kinetic energy was based on the fact that 58-foot pounds is required to deliver a potentially lethal injury. The development project completed, the Aerojet team sent the project back to Picatinny. A claymore mine is command detonated only, meaning the firing device must be manually triggered. 8/21/2019 MacLeod's case collapsed when photographs of the German Trenchmine prototype were produced as evidence of prior art.. The Claymore can also be victim-activated by booby-trapping it with a tripwire firing system for use in area denial operations. The M18 Claymore anti-personnel mine was specifically designed to kill or maim enemy ground troops approaching a position from a specific direction. a. | Content ©www.MilitaryFactory.com. The shape was developed through experimentation to deliver the optimum distribution of fragments at 50 m (55 yd) range. The 100-foot (30 m) M4 electric firing wire on a green plastic spool is provided in each bandolier. 9.  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. All written content, illustrations, and photography are unique to this website (unless where indicated) and not for reuse/reproduction in any form. The blasting cap detonates the C4 explosive in the mine, scattering small steel balls or discs in a 45 deg .angle from the front of the mine.

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 firing system was found to not be wholly reliable, sometimes causing premature detonation of the explosive, so a work around was used to replace the M18 battery holder firing device as issued with a standard M57 firing device instead. The force of the explosion deforms the relatively soft steel balls into a shape similar to a .22 rimfire projectile. In 1960 it was type standardized as the M18A1. They adopted simple peep sights, which were later replaced by a knife blade sight. Its lethality out to 50 metres arrives in the form of 650 steel balls and it is activated by remote control or trip wire. This was found to be undesirable for a number of reasons. When mines are employed in the controlled role, they are treated as individual weapons and are reported in the unit fire plan. Schardin spent some time developing the discovery as a side-attack anti-tank weapon, but development was incomplete at the end of the war. A layer of tinfoil was added between the fragmentation matrix and the explosive. The Arsenal bid it out to various component suppliers. A simple open sight on the top surface allows for aiming the mine. Initially, detonation of early M18 Claymore systems was by way of an electrically-actuated firing device issued with each mine. Two pairs of scissor legs attached to the bottom support the mine and allow it to be aimed vertically. After a number of experiments, the engineers settled on Devcon-S steel-filled epoxy to hold the balls in place. The optimum effective range is 50 m (55 yd), at which the optimal balance is achieved between lethality and area coverage, with a hit probability of 30% on a man-sized target.. The M18A1 Claymore mine has a horizontally convex green plastic case (inert training versions are blue). The advantage of such a weapon was in the wide dispersal of lethal steel ball bearings up to a distance of 100 yards. 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).  It lacked the later version's iconic "FRONT TOWARD ENEMY" marking. On both sides of the sight are fuse wells set at 45 degrees. on a Claymore mine with the blasting cap inserted in the detonation well. You set it … Material presented throughout this website is for historical and entertainment value only and should not to be construed as usable for hardware restoration, maintenance, or general operation. Canada fielded a weapon called the "Phoenix" landmine, which used the Misznay–Schardin effect to project a spray of 0.25-inch (6.4 mm) steel cubes towards the enemy. After Bledsoe left the project to work at the Rheem corporation, William Kincheloe, another engineer, came onto the Claymore project. Because of the blast of explosive when a Claymore is fired, all personnel must be undercover when within 100 meters of the mine and no one should be within 16 meters of the point of detonation. 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). A ferrite choke was added to prevent RF signals and lightning from triggering the mine.. It does not contain an explosive or pyrotechnic filler of any kind. The shape was developed through experimentation to deliver the optimum distribution of fragments at 50 m (55 yd) range. It comes with all the components of a real Claymore kit packed in an M7 bandolier. Secondly, the blast "leaked" between the balls, reducing their velocity. 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. Testing concluded that the mine was effective out to approximately 110 yards (100 m), being capable of hitting 10% of the attacking force. The screenplay for Rambo was written by Art Monterastelli and Sylvester Stallone. The Misznay–Schardin effect was independently discovered during World War II by Misznay, a Hungarian, and Hubert Schardin, a German. It was caused by two claymore mines placed side by side on the bus by LTTE cadres, which spraying the packed bus with millions of ball bearings upon manual detonation. This was determined experimentally by Bledsoe, through a large number of test firings. The mine can be detonated by any mechanism that activates the blasting cap. , A second problem was the curvature of the mine.

The M18 claymore mine is maybe not a household name but I would bet it’s close to it now a days thanks to Hollywood , books and people with hands on experience in the population. It is also used against unarmored vehicles. Since the Claymore has a curved rectangular shape, once fired, plastic explosive hurls 700 steel balls out in a 60° radius. The "Military Factory" name and MilitaryFactory.com logo are registered ® U.S. trademarks protected by all applicable domestic and international intellectual property laws. The cubes were embedded in five pounds of Composition B explosive. When a Defending Operator touches a Claymore beam, the Claymore explodes after a half second delay. The case has the words \"Front Toward Enemy\" embossed on the front of the mine. 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. At 55 yards (50 m), this increased to 30%. 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). It weighs 2 lb (0.91 kg) and has a 50 m (160 ft) effective range, similar to the full-size Claymore. , Following the massed Chinese attacks during the Korean War, Canada and the United States began to develop projects to counter them. c. Position the firing device safety bail in the FIRE position (figure 071-325-4425 ‑13). , MacLeod applied for a patent for the mine on 18 January 1956 and was granted it in February 1961. 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 second change was to use a poured plastic matrix to briefly contain the blast from the explosive, so that more of the blast energy was converted into projectile velocity. It was not until the improved M18A1 was developed that the Claymore became a widely used weapon. It has the surface space of an average smartphone and includes a Picatinny rail for camera, laser, or other attachments. 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). Rambo was preceded by First Blood (1982) (1982), Rambo: First Blood Part II (1985) (1985), and Rambo III (1988) (1988). 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. The Claymore mine is typically deployed in one of three modes: Controlled, Uncontrolled, or Time-delayed. 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. Its lethality out to 50 metres arrives in the form of 650 steel balls and it is activated by remote control or trip wire. Detonation can only be initiated by a shockwave, such as when a detonator inserted into it is fired. , Early pre-production mines were triggered using a battery pack, which had been used with the M18. Its inventor, Norman MacLeod, named the mine after a large medieval Scottish sword. 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. The M18A1 Claymore mine has a horizontally convex green plastic case (inert training versions are blue). Dr. John Bledsoe led the initial project. In total the mine weighed about 2.43-pound (1.10 kg), and could be fitted with an optional peep sight for aiming. 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 used primarily in ambushes and as an anti-infiltration device against enemy infantry. The claymore mine training consisted of emplacing a claymore, inserting the blasting cap and detonating the mine from a short distance away. They were awarded a $375,000 development contract to improve the Claymore design. At its optimized range of 30 m (98 ft), the fragmentation zone is 23 m (75 ft) wide and 2 m (6.6 ft) high, with a minimum of five hits per 1 m2 (11 sq ft). Schardin also spent time researching a "trench mine" that used a directional fragmentation effect. The detonation proceeds at an explosive velocity of 8,092 m/s (26,550 ft/s). He worked with Don Kennedy and the two men submitted a 30-page proposal in response to Picatinny's RFP. , Minor modifications were made to the mine during its service. After locating a suitably low-cost device, the engineers found that fumes from either the C-3 explosive or the cement used to glue the sight to the top of the mine corroded the plastic mirrors, rendering them unusable. Anything exposed within a …  A simple open sight on the top surface allows for aiming the mine. Here is a graphic from the FM for claymores and outlines the safe distances. Using dyes to test various plastics for leaks, they found a suitable plastic called Durex 1661½, which could be easily molded into a case.  The patent was later the subject of a civil court case between MacLeod, the Army, and Aerojet, which further developed the Claymore design. These performed poorly for two reasons. Later when production was ramped up, the design was changed to flat steel scissor, folding-type legs. , Technical challenges to overcome included developing a case to contain the corrosive C-3 explosive that would be durable enough to withstand months of field handling in wide temperature ranges. , The original M18 mine fell far short of Picatinny's requirements. 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. 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. It was awarded a pre-production contract for 1,000 M18A1 Claymores, designated T-48E1 during testing. 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. Type of Directional fragmentation anti-personnel mine. The Claymore fires steel balls, out to about 100 m (110 yd) within a 60° arc in front of the device. In early 2015, the U.S. Army began testing a smaller version of the Claymore called the Mini-Multi-Purpose Infantry Munition (M-MPIMS). 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. 4 x 6″ spike legs are attached to the bottom of the M18 Claymore system to allow the mine to be easily secured into soft grounds. It was first used in Vietnam in the spring or early summer 1966. 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. What makes them different from most anti-tank mines, however, is their smaller size, which enables large numbers to be simultaneously deployed over a large area. They did not spall from the shock of the explosive, but deformed into a useful aerodynamic shape similar to a .22 rimfire projectile. The M18 is a command detonated mine that is directional. With this change, the velocity improved to 3,995 feet (1,218 m) per second. The light blue or black plastic M33 Inert Anti-Personnel Mine is the training and practice version of the M18A1 Claymore. 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. The M57 firing device (colloquially referred to as the "clacker") is included with each mine. 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! The M18a1 claymore mine is based around a 1.5lb slab of plastic explosives packed behind 700 steel balls. 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 M18a1 Claymore can be attached to a trip wire or set off by a timer. 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. 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. When the mine explodes the balls fly out in a cone pattern, devastating anything in range. When detonated, C-4 rapidly decomposes to release nitrogen, water and carbon oxides as well as other gases. 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), at the same time breaking it into individual fragments. Detonation is initiated by a No 2 electric blasting cap. One of the first improvements was to replace the steel cubes with 7⁄32-inch (5.6 mm) hardened 52100 alloy ball bearings. Explosives researcher Norman A. MacLeod used it to design a weapon to counter human-wave assaults, such as those waged by Chinese soldiers against Americans in the Korean War. Two pairs of scissor legs attached to the bottom support the mine and allow it to be aimed vertically. The firing device creates an electrical charge that fires the blasting cap placed inside the mine. We do not sell any of the items showcased on this site. Some inert mines were green with a light blue band. Quiz by Jeffcotton 2 electric 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. (1) Claymore mines can be used for demolition against thin-skinned buildings and walls, or the 1 1/2 pounds of composition C4 can be removed from the mine and used as an explosive, if authorized. It was used in small numbers in Vietnam from around 1961. Rear-safety distance has been decreased to 15 m (49 ft) and shelf life has been increased to 25 years.. The M18A1 Claymore is a directional anti-personnel mine developed for the United States Armed Forces. There are field-expedient methods of detonating the mine by tripwire, or by a timer, but these are rarely used. b. Connect the firing wire to the firing device. In fact, so long as the operator can find a way to actuate the blasting caps, the M18 will trigger. Captain Phillip Esposito and First Lieutenant Louis Allen, from a New York Army National Guard unit of the United States 42nd Infantry Division, were mortally wounded in Esposito's office by a Claymore mine and died. Remove the dust cover from the firing device and firing wire. The case has the words \"Front Toward Enemy\" embossed on the front of the mine. The M68 kit is designed to familiarize personnel with the placement and arming of a real M18 directional mine. The development of the M18A1 mine dates back to work done during World War II.
