M6 Mine
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. Work on the M6 mine began in 1943, after the campaigns in North Africa. Testing had revealed the smaller M1 mine, filled with of TNT, had difficulties breaking the tracks of heavy tanks such as the Tiger I, and it was desired that in addition to correcting technical defects with the M1, a heavy mine similar to the German Teller mine (with of explosives) be available to American forces. After correction of defects in the T6E1, contracts were issued before the mine was standardized, and it began production in May 1944. The T6E1 was standardized as the M6 in September 1944. Because of a lessening need for antitank mines as the Allies went on the offensive in 1944, the T6E1/M6 was not deployed to the European theater. They were superseded in service after WWII by the larger M15 mine. The mine is normally painted olive green and has a large c ...

Anti-tank Landmine
An anti-tank mine (abbreviated to "AT mine") is a type of land mine designed to damage or destroy vehicles including tanks and armored fighting vehicles. Compared to anti-personnel mines, anti-tank mines typically have a much larger explosive charge, and a fuze designed to be triggered by vehicles or, in some cases, Remote control, remotely or by tampering with the mine. History First World War The first anti-tank mines were improvised during the First World War as a countermeasure against the first tanks introduced by the United Kingdom of Great Britain and Ireland, British towards the end of the war. Initially they were nothing more than a buried high-explosive shell (projectile), shell or Mortar (weapon), mortar bomb with its fuze upright. Later, purpose-built mines were developed, including the Flachmine 17, which was simply a wooden box packed with explosives and triggered either remotely or by a pressure fuze. By the end of the war, the Germans had developed row mining tec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anti-handling Device
An anti-handling device is an attachment to or an integral part of a landmine or other munition such as some fuze types found in general-purpose air-dropped bombs, cluster bombs and sea mines. It is designed to prevent tampering or disabling, or to target bomb disposal personnel. When the protected device is disturbed, it detonates, killing or injuring anyone within the blast area. There is a strong functional overlap of booby traps and anti-handling devices. Purpose Anti-handling devices prevent the capture and reuse of the munition by enemy forces. They also hinder bomb disposal or demining operations, both directly and by deterrence, thereby creating a much more effective hazard or barrier. Anti-handling devices greatly increase the danger of munitions to civilian populations in the areas in which they are used because their mechanisms are so easily triggered. An anti-tank mine with an anti-handling device fitted is almost guaranteed to detonate if it is lifted/overturne ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
TNT (explosive)
Trinitrotoluene (), more commonly known as TNT, more specifically 2,4,6-trinitrotoluene, and by its preferred IUPAC name 2-methyl-1,3,5-trinitrobenzene, is a chemical compound with the formula C6H2(NO2)3CH3. TNT is occasionally used as a reagent in chemical synthesis, but it is best known as an explosive material with convenient handling properties. The explosive yield of TNT is considered to be the standard comparative convention of bombs and asteroid impacts. In chemistry, TNT is used to generate charge transfer salts. History TNT was first prepared in 1863 by German chemist Julius Wilbrand and originally used as a yellow dye. Its potential as an explosive was not recognized for three decades, mainly because it was too difficult to detonate because it was less sensitive than alternatives. Its explosive properties were first discovered in 1891 by another German chemist, Carl Häussermann. TNT can be safely poured when liquid into shell cases, and is so insensitive that in ...

Western Sahara
Western Sahara ( '; ; ) is a disputed territory on the northwest coast and in the Maghreb region of North and West Africa. About 20% of the territory is controlled by the self-proclaimed Sahrawi Arab Democratic Republic (SADR), while the remaining 80% of the territory is occupied and administered by neighboring Morocco. Its surface area amounts to . It is one of the most sparsely populated territories in the world, mainly consisting of desert flatlands. The population is estimated at just over 500,000, of which nearly 40% live in Laayoune, the largest city in Western Sahara. Occupied by Spain until 1975, Western Sahara has been on the United Nations list of non-self-governing territories since 1963 after a Moroccan demand. It is the most populous territory on that list, and by far the largest in area. In 1965, the United Nations General Assembly adopted its first resolution on Western Sahara, asking Spain to decolonize the territory. One year later, a new resolution was ...

Thailand
Thailand ( ), historically known as Siam () and officially the Kingdom of Thailand, is a country in Southeast Asia, located at the centre of the Indochinese Peninsula, spanning , with a population of almost 70 million. The country is bordered to the north by Myanmar and Laos, to the east by Laos and Cambodia, to the south by the Gulf of Thailand and Malaysia, and to the west by the Andaman Sea and the extremity of Myanmar. Thailand also shares maritime borders with Vietnam to the southeast, and Indonesia and India to the southwest. Bangkok is the nation's capital and largest city. Tai peoples migrated from southwestern China to mainland Southeast Asia from the 11th century. Indianised kingdoms such as the Mon, Khmer Empire and Malay states ruled the region, competing with Thai states such as the Kingdoms of Ngoenyang, Sukhothai, Lan Na and Ayutthaya, which also rivalled each other. European contact began in 1511 with a Portuguese diplomatic mission to Ayuttha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Explosive Booster
{{unreferenced, date=August 2011 An explosive booster is a sensitive explosive charge that acts as a bridge between a (relatively weak) conventional detonator and a low-sensitivity (but typically high-energy) explosive such as TNT. By itself, the initiating detonator would not deliver sufficient energy to set off the low-sensitivity charge. However, it detonates the primary charge (the booster), which then delivers an explosive shockwave that is sufficient to detonate the secondary, main, high-energy charge. Unlike C4 plastic explosive, not all explosives can be detonated simply by inserting a detonator and firing it. An initiator such as a shock tube, cannon fuse, or even a conventional detonator does not deliver sufficient shock to detonate charges comprising TNT, Composition B, ANFO and many other high explosives. Therefore, some form of "booster" is required to amplify the energy released by the detonator so that the main charge will detonate. At first, picric acid ...

Detonator
A detonator, frequently a blasting cap, is a device used to trigger an explosive device. Detonators can be chemically, mechanically, or electrically initiated, the last two being the most common. The commercial use of explosives uses electrical detonators or the capped fuse which is a length of safety fuse to which an ordinary detonator has been joined. Many detonators' primary explosive is a material called ASA compound. This compound is formed from lead azide, lead styphnate and aluminium and is pressed into place above the base charge, usually TNT or tetryl in military detonators and PETN in commercial detonators. Other materials such as DDNP (diazo dinitro phenol) are also used as the primary charge to reduce the amount of lead emitted into the atmosphere by mining and quarrying operations. Old detonators used mercury fulminate as the primary, often mixed with potassium chlorate to yield better performance. A blasting cap is a small sensitive primary explosive dev ...
