TMD-44 and TMD-B mines

Last updated

The TMD-44 and TMD-B are simple rectangular Russian wooden box cased anti-tank blast mines, they were both used during the Second World War. Both mines are similar in design, differing only in fuzing mechanism. The wooden construction of both the mines makes them unpredictable as rot and insects can eat away the wooden case, reducing activation pressure to as little as 3 kg. Both mines are found in a number of countries including Afghanistan, Angola, Chad, Cuba, Egypt, Korea, Mozambique, Namibia, Rwanda, Yemen, Zambia, and Zimbabwe.

Anti-tank mine form of land mine designed for use against armored vehicles (including tanks)

An anti-tank mine is a type of land mine designed to damage or destroy vehicles including tanks and armored fighting vehicles.

Afghanistan A landlocked south-central Asian country

Afghanistan, officially the Islamic Republic of Afghanistan, is a landlocked country located in South and Central Asia. Afghanistan is bordered by Pakistan in the south and east; Iran in the west; Turkmenistan, Uzbekistan, and Tajikistan in the north; and in the far northeast, China. Its territory covers 652,000 square kilometers (252,000 sq mi) and much of it is covered by the Hindu Kush mountain range, which experiences very cold winters. The north consists of fertile plains, whilst the south-west consists of deserts where temperatures can get very hot in summers. Kabul serves as the capital and its largest city.

Angola country in Africa

Angola, officially the Republic of Angola, is a west-coast country of south-central Africa. It is the seventh-largest country in Africa, bordered by Namibia to the south, the Democratic Republic of the Congo to the north, Zambia to the east, and the Atlantic Ocean to the west. Angola has an exclave province, the province of Cabinda that borders the Republic of the Congo and the Democratic Republic of the Congo. The capital and largest city of Angola is Luanda.

TMD-B info and image from a US Military manual.

The TMD-B was developed before the start of the Second World War and is simply a wooden box filled with explosives, there are three raised boards on the top of the box, the central one being hinged. The central hinged board is locked into place by a strip of wood inserted into a groove that runs along the edge of all three boards. When enough pressure is applied to the top of the mine the boards collapse onto the plunger of the MV-5 detonator, triggering the mine. A fabric carrying handle is typically fixed to one side of the mine. It was normally painted olive green, gray or white.

One problem with the mine was that when it got wet the hinged board would tend to swell making it difficult to disarm the mine, this issue was addressed in the TMD-44 mine.

The mine has been copied by a number of other countries, including the Chinese Model 1951, the North Korean ATM-72, and the Yugoslavian TDM-1 and TMD-2.

North Korea Sovereign state in East Asia

North Korea, officially the Democratic People's Republic of Korea, is a country in East Asia constituting the northern part of the Korean Peninsula, with Pyongyang the capital and the largest city in the country. The name Korea is derived from Goguryeo which was one of the great powers in East Asia during its time, ruling most of the Korean Peninsula, Manchuria, parts of the Russian Far East and Inner Mongolia, under Gwanggaeto the Great. To the north and northwest, the country is bordered by China and by Russia along the Amnok and Tumen rivers; it is bordered to the south by South Korea, with the heavily fortified Korean Demilitarized Zone (DMZ) separating the two. Nevertheless, North Korea, like its southern counterpart, claims to be the legitimate government of the entire peninsula and adjacent islands.

Yugoslavia 1918–1992 country in Southeastern and Central Europe

Yugoslavia was a country in Southeastern and Central Europe for most of the 20th century. It came into existence after World War I in 1918 under the name of the Kingdom of Serbs, Croats and Slovenes by the merger of the provisional State of Slovenes, Croats and Serbs with the Kingdom of Serbia, and constituted the first union of the South Slavic people as a sovereign state, following centuries in which the region had been part of the Ottoman Empire and then Austria-Hungary. Peter I of Serbia was its first sovereign. The kingdom gained international recognition on 13 July 1922 at the Conference of Ambassadors in Paris. The official name of the state was changed to Kingdom of Yugoslavia on 3 October 1929.

TMD-44

The TMD-44 entered service with the Red Army in 1944, and essentially was simply the TMD-B mine with the central hinged board replaced with a Bakelite fuze cap, this solved the disarming issue with the earlier TMD-B.

Red Army 1917–1946 ground and air warfare branch of the Soviet Unions military

The Workers' and Peasants' Red Army, frequently shortened to Red Army was the army and the air force of the Russian Soviet Federative Socialist Republic, and, after 1922, the Union of Soviet Socialist Republics. The army was established immediately after the 1917 October Revolution. The Bolsheviks raised an army to oppose the military confederations of their adversaries during the Russian Civil War. Beginning in February 1946, the Red Army, along with the Soviet Navy, embodied the main component of the Soviet Armed Forces; taking the official name of "Soviet Army", until its dissolution in December 1991.

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.

Copies of the TMD-44 are produced in North Korea as the ATM-44, and the Yugoslavian TMD-B and TMD-1 are extremely similar.

Tellermine 43

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 PP Mi-D mine is a Czech copy of the German Second World War Schu-mine 42 anti-personnel mine.

PMD series mines

The PMD-6, PMD-7 and PMD-57 series mines are Soviet Union blast type anti-personnel mines that consist of a wooden box with a hinged lid with a slot cut into it. The slot presses down against a retaining pin, which holds back the striker. When sufficient pressure is applied to the lid of the box the retaining pin moves, allowing the striker to hit the detonator. The mines typically have an operating pressure of 1 to 10 kg. All the mines in the series use MOV series fuzes.

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.

PMN mine

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.

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.

M19 mine

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 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.

Riegel mine 43

The Riegel mine 43 or is a German steel cased anti-tank bar mine used during the Second World War. The mine is a long thin rectangle. It consists of a lower and upper metal tray, and an internal metal-cased explosive block. It uses two ZZ42 fuzes inserted into either end of the internal block, although it can be used with an additional pressure fuze on the top. The mine is similar to the Italian B-2 mine. A variant, the Riegel mine 44 was also produced with a different fuze. Approximately 3,051,400 were produced between 1943 and 1945.

The MAT-76 is a large circular Romanian minimum metal anti-tank blast mine. It is similar to the MAT-62B mine, sharing a fuze. The mine is actually a cast block of TNT with a thin coating of fibreglass. The mine has a central fuze well that normally uses a P-62 pressure fuze, although it can be used with any of the fuzes designed for the Russian TM-62 and TM-72 series of mines. The bakelite plastic used in the fuze of a MAT-76 may become brittle in desert conditions, which can reduce the activation pressure. This may make the mine unstable i.e. can detonate simply by handling it. The mine is found in Angola, Iraq, Kuwait, Liberia, Mozambique, and Zambia.

TMA-1 mine

The TMA-1 and TMA-1A are circular, plastic cased Yugoslavian minimum metal anti-tank blast mine. The mine consists of an upper plastic pressure plate, and the lower body containing the main charge. The pressure plate has eight triangular raised sectors, and a central fuze cap. The pressure plate is held in place by four plastic pins, which when suffient pressure is applied, shear allowing the pressure plate to collapse onto the mine body, triggering the UANU-1 fuze. A secondary fuze well is provided in the base of the mine, allowing the use of anti-handling devices. The mine is found in Bosnia, Croatia and Kosovo.

TMA-2 mine

The TMA-2 is a rectangular plastic cased Yugoslavian minimum metal anti-tank blast mine. It is very similar in appearance and size to the PT-56, which it replaced. The mine consists of two sections, an upper ribbed pressure plate with two large circular fuze caps, and a lower base section containing the main charge and two primary fuze wells containing UANU-1 fuzes. A secondary fuze well is provided in the base of the mine for an anti-handling device.

TMA-3 mine

The TMA-3 is a circular Yugoslavian minimum metal anti-tank blast mine. It is very similar in appearance to the TMA-4. The mine consists of a cast circular block of explosive cased in resin reinforced fabric. The top of the mine has three fuze wells which each take a UTMA-3 fuze, and a fourth secondary fuze well is provided in the base of the mine to fit an anti-handling device. The fuze wells may also accept a number of other fuzes, including the UPROM-1, and other fuzes, potentially allowing tripwire activation. The small pressure plate area of the UTMA-3 fuzes gives the mine good resistance to minefield clearance techniques which used blast overpressure techniques i.e. explosive charges.

The TMA-5 and TMA-5A are rectangular plastic cased Yugoslavian minimum metal anti-tank blast mines. The mine's top surface has a single circular threaded fuze cap in the center, covering the fuze well. Additionally there is a small compartment for storing the fuze when disarmed. The corners of the mine have small posts to permit stacking of the mine. Although the mine does not have a secondary fuze well, it could easily be fitted with an improvised one in the field. The mine uses a single black plastic UANU-1 fuze.

The TMD-1 and TMD-2 are Yugoslavian wooden cased anti-tank blast mines, similar to the Russian TMD-B. The box consists of a wooden box, which contains the main cast TNT main charge. A webbing carrying handle is provided on one side of the mine. The fuze is placed in a central detonation well under the centre board of three that are fixed to the top of the mine. When sufficient pressure is placed on the boards, they collapse inwards, pressing on the installed fuze triggering the mine.

The TMM-1 is a circular, metal-cased, Yugoslavian anti-tank blast mine. It is a direct copy of the German Tellermine 43. The mine has a central fuze well that is covered by a screw on pressure plate. Two secondary fuze well are fitted to the side and bottom of the mine allowing the installation of anti-handling devices. The mine is found in Bosnia, Croatia, and Kosovo.

The Model 67 is a square plastic cased Austrian minimum metal anti-tank blast mine. The mines pressure fuze sits on the top of the mine, with a provision for an anti-handling device. A second version of the mine the ATM-75 is similar to the Model 67 mine.

ATM-72 mine

The ATM-72 is a steel cased circular North Korean anti-tank mine. It is similar to the Russian TM-46, with a thick wire carrying handle and a filling plug. The mine uses a four pronged fuze, downward pressure on any of the levers will trigger the mine. The lever action of the mine makes it resistant to overpressure and blast.

The ATM-74 is a North Korean wooden box mine, it is a copy of the Russian TMD-B. It is a wooden box packed with blocks of TNT, the top of the mine has three planks of wood underneath the central plank is a pressure fuze similar to Russian MV-5 pressure fuze.

The TMD-40 was a wooden-cased Soviet anti-tank blast mine used during the Second World War. The mine consisted of a rectangular wooden box which contained a detonator assembly at each end and seven 400 gram and four 200 gram blocks of explosive. The fuse assemblies consisted of a lever device, which when pressed downward by pressure pieces attached to the lid of the mine, see-sawed upward, pulling the striker retaining pin from a pull detonator. The main charge was then triggered.
