This book is for information purposes only. They operate much like giant shotguns, propelling projectiles at bad guys in a manner that discourages them from going places where they suspect claymores are present. Generally, claymore mines are thought of as relatively small, light, inexpensive counters against unfriendly personnel.
But heavier, more powerful claymores are gaining acceptance for use against vehicles and aircraft. The Swedish FFV, for instance, weighs 44 pounds and is advertised as being effective against helicopters at meters!
Because claymore-type mines are so extremely effective and because they represent a quantum leap in technology for the hapless, ground-pounding soldier, paramilitary-type people have taken notice. What are normally considered to be civilians have made numerous attempts recently to home-manufacture directional mines for their own use.
This includes many paramilitary-type devices produced by insurgents in places as diverse as Vietnam, Nicaragua, Guatemala, Peru, and Northern California. Some of the devices these people have come up with weigh up to 50 pounds each and are layered with projectiles reminiscent of those said to have been used in early firearms, comprised of little more than a miscellaneous collection of old bolts, nuts, washers, nails, and metal chips.
Effective range of most of these home-built devices, especially vis-a-vis their weight and expense, has not proven particularly good. Attempts to home-produce good, effective, workable directional mines have been fraught with numerous problems. In most cases the makers did not understand the physical concepts by which claymores functioned. Claymores operate on some sophisticated physical principles of explosives that cannot be altered.
Store-bought, off-the-shelf components can be used—and are, in fact, used—in commercially produced claymores. But one must use exactly the correct components in the exact quantities prescribed, or the end result is poor. Claymore mines operate on principles that are close relatives to those of the Munroe shaped charges. Shaped charges are very exacting creatures that must be set up on close tolerances if they are to yield acceptable results.
Another problem, even for those who were willing to take care in the manufacturing process and treat the project as an intricate shaped-charge design, involved the fact that very few of them had any idea how claymores actually worked. In spite of the fact that claymore mines are very simple and very common, there is very little information on the basic operating theories out on the market. Prestigious armament encyclopedias often completely ignore both the history and operating principles of claymores.
Many peripheral references fail to even mention claymore mines, in spite of the fact that claymore technology has played a major role in the conduct of battle for the last 40 years. However, Paladin Press in Boulder, Colorado, has recently published an excellent volume on the history and development of claymore mines, including a detailed analysis of their commercial assembly and theory of operation, entitled Claymore Mines: Their History and Development.
Readers who wish to know more about the Munroe theory of shaped charges and its application to directional mines should obtain a copy of this book. Past problems notwithstanding, this new Paladin book proved that homemade directional mines are practical if put together correctly. From it we learned that they are also reasonably simple to assemble from existing over-the-counter supplies.
The only assumption made in this "how to" manual involves obtaining the explosives needed to energize these devices. This is not a text pertaining to proper use and handling of high explosives. It is assumed, therefore, that builders know how to purchase or make suitable explosives and safely handle them. Homemade claymore mines are extremely dangerous devices. They produce both a front and back blast, either of which can be deadly.
Those who do not know specifically how to deal with the grim realities of modern military-grade explosives are advised to regard this book as being for informational purposes only. Do not try to make these devices under any circumstances unless you have an excellent working knowledge of explosives and have acquired the appropriate legal permissions from local, state, and federal authorities. United States Marines serving in November of north of the Chosin Reservoir in North Korea were suddenly hit by an incredible wave of human attackers.
Mao had committed more than , of his soldiers to prop up the tottering regime of Kim II Sung. As a result, hundreds of thousands of enemy soldiers overran American and Republic of Korea positions, often with impunity. Approximately 44, of the 55, casualties the United States incurred in Korea were attributed to these human-wave attacks.
As a result of the United Nations experience in Korea, armament experts throughout the world explored the possibility of perfecting a light, relatively cheap, easily deployed, directional-type mine that per- formed much like a giant shotgun. Actually, the Boers used a similar concept in their war in Called "rift mines," they were little more than high explosives placed beneath bits and pieces of iron, steel, and rock.
British guards used something similar at Gibraltar called "rock mines. Results were uneven, however, and the device was not really portable. The first physicist-type scientist to ponder the idea that explosives might be designed to throw projectile-like fragments from a flat explosive surface without employing a barrel was a German named Hubert Schardin.
Schardin worked for the German Luftwaffe during World War II and then went on to achieve some notoriety as an explosives physicist in postwar Germany. Schardin was joined by a mysterious Hungarian scientist named Misznay.
Little— not even his first name—is known about Misznay, who disappeared behind the Iron Curtain in , never to reappear. Together briefly, Misznay and Schardin postulated that projectiles could be thrown accurately and predictably from the face of a flat explosive charge.
Schardin attempted to develop a directionaltype mine called a "trench mine" at the end of World War II, to be used in the static trench warfare German military brass envisioned. There are apparently no surviving examples. Schardin also attempted to develop a warhead that threw fragments in a predictable pattern to be used to shoot down Allied Bs flying at very high altitudes, where standard flak rounds were less efficient.
American and British agents, in turn, attempted to steal this technology from the Germans for use in shooting down incoming V-2 rockets. It was the very beginnings of "Star Wars" technology, though no one used that terminology at the time. MacLeod, worked at China Lake Naval Ordnance test station, China Lake, California, on precision-engineered, conventional explosives used to detonate nuclear devices.
MacLeod took great exception to the fact that waves of Communist Chinese soldiers were running roughshod over our marines. Driven by his genuine concern for the GI in the foxhole, his excellent ability with precision explosives, and his knowledge of historic and contemporary developments in the field of directional mines, MacLeod started to tinker with a small directional mine. At the same time, Canadian munitions experts—similarly motivated by their experience in Korea—began work on a device they called the "Phoenix.
He interested Picatinny Arsenal in New Jersey in developing a directional mine and was eventually issued a contract to do research. How long MacLeod worked on the concept of claymore mines is lost in history, but in mid, just as the Korean police action was drawing to a conclusion, he came out with an approximately 3-pound device that threw about steel cubes.
Because of the poor aerodynamic qualities of cubes, effective range was less than feet. Penetration and target coverage were also minimal.
MacLeod persisted in his use of cubes, attempting to better seal the explosives forces behind the fragments. Although it was still not a particularly effective weapon, the Marine Corps accepted it and designated it the M18 claymore.
Ironically, MacLeod named his mine after the legendary claymore sword. Historic members of the Scottish MacLeod clan had, in several wars and insurrections throughout the British Isles in the early s, distinguished themselves in the use of the deadly two-handed claymore sword. Norman MacLeod secured a contract to produce 10, postdevelopment model Ml8s, which were used for testing, training and, to a limited extent, in combat between and In , Picatinny Arsenal decided to upgrade and improve the M It sent out RFPs requests for proposals to numerous defense contractors, many of which were springing up around the United States in response to the increased need for defense research with the onset of the Cold War.
Aerojet Corporation in Azusa, California, had a team of proven rocket-, explosives-, and munitions-development specialists who believed they could meet the requirements as set out by Picatinny. Four munitions physicists working for Aerojet at the time, John Bledsoe, Don Kennedy, Bill Kincheloe, and Guy Throner, ended up spending about a year perfecting the claymore.
All four are alive today and recall that the package was, in their words, a "blivet. Among others, they were being asked to produce a device weighing no more than 3. By early summer of , the team had a good working prototype that met most military specs. It was at this time, while working with regular GIs, that they finalized the peephole sight design. Today, nonexplosive components of the mine are manufactured and assembled by various contractors, selected on the basis of the lowest and best bid.
The one in Shreveport, Louisiana, is about to close due to lack of business. Another, near Burlington, Iowa, will continue to load the few claymores used by the U. Contrary to what the popular media portrayed, human-wave attacks were used extremely infrequently in Vietnam. United Nations forces deployed claymores to defend their positions in Saudi Arabia during Desert Storm, but, due to the nature of that conflict, few, if any, were actually discharged in anger.
On a worldwide basis, claymore mines represent the only significant leap in basic weapons technology for the lowly groundpounder to come along in years. Through the centuries, gradual improvements have been made in infantry items such as rifles, pistols, hand grenades, mortars, and uniforms.
But all of these evolved gradually and generally represented improvements to existing systems. Claymores were all new in design and application. Weapons manufacturers in South Korea, Israel, and Sweden began manufacturing claymore-type mines in various sizes and configurations.
Some systems are closer to antiarmor devices than antipersonnel-type claymores. American manufacturers found that markets in which they formerly enjoyed a monopoly were now characterized by competition. Domestically, individuals who wished to make use of commercial detonated devices to protect freedom, life, and property found the claymore concept to be ideal under many circumstances.
However, numerous federal and state laws preclude the legal purchase and ownership of commercial claymore mines. Reportedly, home manufacture of claymore mines has become quite a cottage industry in some places in the United States. Although field reports regarding their effectiveness are extremely sketchy, one can validly conclude that the performance of these devices is not particularly good. Generally, claymores can be assembled from off-the-shelf components.
But like all shaped charges, final assembly is very exacting. If one uses the wrong components, even though superficially they might seem able to do the job, end results will be mediocre to poor at best Fortunately, all of the critical components necessary to home-build claymore mines can, with varying degrees of diligence, be purchased off the shelf.
