M1 mine

The M1, M1A1 and M4 are circular steel cased United States anti-tank blast mines with a distinctive cross shaped pressure spider. The mine was used during the Second World War and a copy produced in Argentina was used during the Falklands War. Another copy is produced in China, there designated as the No. 4 mine. Variants of the mine have also been deployed in Chad and Tunisia.

Downward pressure on the spider presses down on the head of the fuze, breaks a shear pin, and inverts a belleville spring, flipping the striker downwards into a stab sensitive detonator, triggering the mine. The M4 version of the mine has two secondary fuze wells so that anti-handling devices can be fitted.

The Tellermine 35 (T.Mi.35) was a German metal-cased anti-tank mine used extensively during the Second World War. The mine's case is made of sheet steel, and has a slightly convex pressure plate on the top surface with a central fuze well. Two secondary fuze wells are located on the side and bottom of the mine for anti-handling devices.

The M26 is a fragmentation hand grenade developed by the United States military. It entered service around 1952 and was used in combat during the Korean War. Its distinct lemon shape led it to being nicknamed the "lemon grenade".

<span class="mw-page-title-main">Tellermine 42</span> German anti-tank mine

The Tellermine 42 (T.Mi.42) was a German metal-cased anti-tank blast mine used during the Second World War. The mine was a development of the Tellermine 35 with improved resistance to blast. It was followed by the simplified Tellermine 43. The Tellermine consists of a circular pressed steel main body with a large central pressure plate. The pressure plate is smaller than the earlier Tellermine 35, which increases the mine's resistance to blast. Two secondary fuze wells are provided for anti-handling devices, one in the side, and one on the bottom of the mine. The mine has a carrying handle.

<span class="mw-page-title-main">Tellermine 43</span>

The Tellermine 43 was a German circular steel cased anti-tank blast mine used during the Second World War. It was a simplified version of the Tellermine 42, which enabled simpler production techniques. Between March 1943 and the end of World War II, over 3.6 million Tellermine 43s were produced by Germany. Copies of the mine were produced by several countries including Denmark (M/47), France and Yugoslavia (TMM-1).

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 PMN series of blast anti-personnel mines were designed and manufactured in the Soviet Union. They are one of the most widely used and commonly found devices during demining operations. They are sometimes nicknamed "black widow" because of their dark casings.

<span class="mw-page-title-main">M15 mine</span>

The M15 mine is a large circular United States anti-tank blast mine, first deployed during the Korean War. Essentially, it is a larger version of the M6A2 anti-tank mine, which it replaced. Although the M15 has been superseded by the M19 mine, the U.S. retains large stocks of M15s because they are still regarded as reliable and effective weapons. When used against main battle tanks the M15 is primarily a "track-breaker" which creates mobility kills, but has a comparatively small likelihood of causing crew fatalities. However, when used against light vehicles such as APCs or unarmored vehicles such as trucks the damage it can inflict is much more severe.

<span class="mw-page-title-main">VS-50 mine</span>

The VS-50 is a circular plastic-cased anti-personnel blast mine that entered production in 1985. It was formerly made by the now-defunct Valsella Meccanotecnica SpA, an Italian high-tech defence company specialized in area denial systems. The company also the made the Valmara 69, and was one of the first to implement plastic construction for landmines. The VS-50's design is similar to that of the TS-50 and VS-MK2 mines. It is blast resistant and can be used in a minimum metal configuration. Though unlikely to kill, its explosive charge is quite sufficient to destroy the victim's foot, being capable of penetrating 5 mm of mild steel leaving an 80 mm-diameter hole.

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.

<span class="mw-page-title-main">M19 mine</span>

The M19 is a large square plastic cased United States anti-tank blast mine. Intended to replace the M15 mine, the design dates from the mid-1960s and contains only two metal components: the copper detonator capsule and a stainless steel firing pin which weighs 2.86 grams. It is a minimum metal mine, which makes it very difficult to detect after it has been emplaced. This mine is produced under licence in Chile, South Korea and Turkey. A copy is produced in Iran. It is found in Afghanistan, Angola, Chad, Chile, Cyprus, Iran, Iraq, Jordan, South Korea, Lebanon, the Western Sahara, and Zambia.

The PM-60 or K-1 is a German round plastic cased minimum metal anti-tank blast mine. The case of the mine consists of two halves joined together by sixteen plastic nuts, giving the mine a distinctive appearance. The top of the mine has a large pressure plate which rests on top of the fuze assembly. Two fuzes are available for the mine, a conventional ball bearing retained striker and a chemical fuze, containing a glass ampule of acid over a flash composition. When the mine is deployed with the chemical fuze it is very difficult to detect because the only metal in the mine is the detonator capsule. There is a secondary fuze well on the bottom of the mine that can accept a fuze allowing remote command detonation of the mine.

The SACI is an Italian Bakelite cased minimum metal anti-tank blast landmine. A number of variants were produced with varying amounts of explosive. The mine has three fuze wells on the top surface, that are covered with a pressure plate. Several types of fuzes were made including a low metal fuze. Combined with the low metal fuze the mine is very difficult to detect with mine detectors.

The PRB M3 and PRB M3A1 are plastic cased minimum metal anti-tank blast mine produced by the Belgian company Poudreries Réunies de Belgique in the 1970s and 1980s. The mine is square with an olive drab body constructed from polythene with a webbing carrying handle on the side and an ammonia-free bakelite seating for the pressure plate to be screwed into. The fuze well is in the centre of the seating, with the pressure plate screwed into it after the fuze has been inserted. The cylindrical pressure plate consists of two plastic plates, one of which moves under the weight of a vehicle driving over the mine to transmit the force to the fuze, shearing pins which hold it in place.

The M6, M6A1 and M6A2 are a series of metal-cased, circular, heavy anti-tank landmines produced by the United States from May 1944 to May 1945.

<span class="mw-page-title-main">TC/2.4 mine</span>

The TC/2.4 is a circular plastic cased Italian minimum metal anti-tank blast mine. The mine uses a blast and shock resistant pneumatic fuze. It could be laid by hand or mechanically, and could be fitted with anti-handling devices. An Egyptian copy of the mine is produced, designated as the M/80. The mine was used in Iraq, but is no longer produced.

<span class="mw-page-title-main">LPZ mine</span>

The L.P.Z. mine or Leichte Panzermine was a circular, metal-cased German anti-tank mine produced during the Second World War. The mine was accepted into service in 1941, and were intended for use by Paratroops. Production of the mine ended in 1942 with only 31,700 mines produced. The mines were first used during Operation Merkur, the airborne invasion of Crete and were still in use at the end of the war.

In military munitions, a fuze is the part of the device that initiates function. In some applications, such as torpedoes, a fuze may be identified by function as the exploder. The relative complexity of even the earliest fuze designs can be seen in cutaway diagrams.
