AUPS mine

Last updated

The AUPS is a circular Italian bakelite cased minimum metal anti-personnel blast mine. The mine can be adapted with a steel fragmentation jacket and stake into a fragmentation stake mine. The mine is constructed in two halves, with the upper half containing the pressure fuse mechanism, the lower half contains the main charge and the detonator. The mine case is normally unpainted bakelite brown.

Bakelite early plastic

Bakelite or polyoxybenzylmethylenglycolanhydride was the first plastic made from synthetic components. It is a thermosetting phenol formaldehyde resin, formed from a condensation reaction of phenol with formaldehyde. It was developed by the Belgian-American chemist Leo Baekeland in Yonkers, New York, in 1907.

Minimum metal mine

A minimum metal mine is a land mine that is designed to use the smallest amount of metal possible in its construction. Typically, the only metal components are located inside the fuze mechanism which triggers detonation. Both minimum metal anti-tank and anti-personnel mines exist. Some designs contain virtually no metal at all e.g. less than a gram. This is achieved by encasing the explosive charge in a plastic, wooden, or glass body, with metallic components limited to the few small parts in the fuze which can not easily be made from other materials, such as the spring, striker tip, and shear pin. Minimum metal mines are extremely difficult to detect using conventional metal mine detectors and usually require modern techniques, such as robotic Multi Period Sensing (MPS) equipment, to identify, but it is still too difficult to find non-metallic mines. These techniques are usually restricted to well-funded international mine clearing organizations and major militaries, making minimum metal mines especially pernicious where they are encountered.

Anti-personnel mine form of land mine designed for use against humans

Anti-personnel mines are a form of mine designed for use against humans, as opposed to anti-tank mines, which are designed for use against vehicles. Anti-personnel mines may be classified into blast mines or fragmentation mines, the latter may or may not be a bouncing mine.

When used as a stake mine the mine is inverted and an MUV type pull fuse is inserted into the base of the mine, and the normal pressure fuse hole is used to attach the mine to the stake. When used with the fragmentation jacket the mine has a lethal radius of 15 metres, although the fragments may be lethal at greater range.

Specifications

Composition B

Composition B, colloquially "Comp B", is an explosive consisting of castable mixtures of RDX and TNT. It is used as the main explosive filling in artillery projectiles, rockets, land mines, hand grenades and various other munitions. It was also used for the explosive lenses in the first implosion-type nuclear weapons developed by the United States.

M18 Claymore mine anti-personnel mine

The M18A1 Claymore is a directional anti-personnel mine developed for the United States Armed Forces. Its inventor, Norman MacLeod, named the mine after a large Scottish medieval sword. 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. The Claymore can also be victim-activated by booby-trapping it with a tripwire firing system for use in area denial operations.

MON-50

The MON-50 is a claymore shaped, plastic bodied, directional type of anti-personnel mine designed and manufactured in the Soviet Union. It is designed to wound or kill by explosive fragmentation. The mine is similar to the American M18 Claymore with a few differences.

MRUD

The MRUD is a plastic bodied, convex rectangular directional type anti-personnel mine designed to wound or kill by fragmentation. It is broadly similar to the M18A1 Claymore mine.

The MON-90 is a claymore shaped, plastic bodied, directional type of anti-personnel mine designed and manufactured in the Soviet Union. It is designed to wound or kill by fragmentation. The mine is similar in appearance to the MON-50, but is approximately twice the size with a much greater depth.

MON-100

The MON-100 is a circular, sheet metal bodied, directional type of anti-personnel mine designed and manufactured in the early 1960s by the Soviet Union. It is designed to wound or kill by fragmentation and resembles a large bowl.

The POMZ, POMZ-2 and POMZ-2M are three types of Soviet-made stake mounted anti-personnel fragmentation mine. The POMZ mine was used during the Second World War. It was superseded by the POMZ-2, and later by the improved POMZ-2M. These mines have been used in numerous conflicts, including the Vietnam War and the Korean War.

The M7 is a small, metal-cased United States anti-tank blast mine that was used during the Second World War. It was based on the British Hawkins grenade. Approximately 2.5 million were produced before production ceased, and although it has long since been withdrawn from U.S. service, it can be found in Angola, Burma, Cambodia, Chad, Eritrea, Ethiopia, Korea, Lebanon, Myanmar, Somalia, Thailand, and Zambia.

Valmara 59

The Valmara 59 is a large cylindrical Italian bounding anti-personnel mine. It is the first in the "Valmara" family of mines produced by Valsella Meccanotecnica, and was followed by the Valmara 69 and VS-JAP. The mine's body is metal with a distinctive five-pronged head. The central prong has a hole, to allow the threading a trip wire. The inner body of the mine has a main charge surrounded with approximately 1,000 steel cubes, below which is a steel wire connecting it to the base of the mine. When the mine is triggered a small charge launches the mine into the air approximately 45 cm before the steel wire is pulled taut, the jolt of which pulls a striker into the detonator. A secondary time fuse triggers the mine after three seconds if it has not detonated after being triggered.

The PT Mi-Ba is a circular Bakelite cased Czechoslovakian minimum metal anti-tank blast mine. The mine entered service with the Czech and Slovakian armies in the 1950s and is now obsolete and no longer in service. The mine is conventional in layout with a central pressure plate, and doughnut-shaped main charge around a booster charge and RO-7-II fuze. The mine's fuze is the only component that contains any metal, and this is limited to a spring, the striker pin, and the detonator capsule.

The Na-Mi-Ba is a Czechoslovakian minimum metal bakelite cased anti-tank blast mine. The mine uses a horizontal lever fuze, with a very low operating pressure that breaks open a glass capsule containing acid, which initiates a flash composition. The mine has a small main charge, and is normally used as the initiator for larger charges. The low operating pressure means that the mine could be used as an anti-personnel mine.

The NR-413 is a Belgian trip wire activated anti-personnel stake mine. The main body of the mine is wine bottle shaped, with an NR 410 tripwire fuse screwed into a fuse well on the top of the mine. Under the fuse well is a detonator and a row of booster pellets. Wrapped around the detonator and booster pellets is the main charge. An internally square cross-sectioned steel wire is coiled around the outside of the mine, which give a fragmentation effect. The mine produces 600 fragments with a velocity of approximately 1,660 metres per second. It has an effective range of around 15 metres. A variant is produced with a cast steel fragmentation jacket.

The MBV-78-A2 is a small cylindrical Vietnamese anti-personnel fragmentation stake mine. It is unrelated to the MBV-78-A1. The mine has a large plastic head which contains the main charge wrapped around the detonator. A fragmentation layer of steel pieces set into wax surrounds the main charge. The plastic head has two mounting lugs for stake mounting the mine. A Vietnamese copy of the Russian MUV fuze is typically used with the mine, although other fuzes could be used.

The Model 49 is a large cylindrical Swiss anti-personnel stake mine. The mine is no longer in service with Swiss forces and all operational stocks of the mine have been destroyed. The mine is normally stake mounted, and uses the ZDZ-39 fuze, which can be operated by either pull or tension release. The mine has a concrete fragmentation jacket with embedded steel fragments.

The P-25 is a plastic cased Italian anti-personnel stake mine. It was developed along with the larger P-40 mine in the late 1970s by Misar SpA and entered production in 1978. The mine consists of a plastic cylinder with a fuse protruding from the top. The mine can either be stake mounted or buried, although it was designed to be stake mounted. Pull pressure on the tripwire results in the fuse head tilting sideways, releasing a striker into the detonator assembly.
