M24 Mine
The M24 mine is a United States off-route land mine based on the M28A2 high-explosive anti-tank (HEAT) rocket normally fired by an M20 Super Bazooka 3.5 inch rocket launcher. The rocket was launched from an M143 plastic launch tube. Operation A trigger cable is laid across a road. When enough pressure occurs in the cable, two conductors inside the cable are forced together closing a circuit. The trigger cable consists of two segments, requiring simultaneous pressure on both segments to trigger the mine. For wheeled vehicles, the cable is laid directly across a road so that wheels on both sides of the vehicle will touch the cable at the same time. For tracked vehicles, the cable is laid at an angle of fifteen degrees to prevent the cable slipping between the treads on the tracks and thus sensing no pressure. The rocket has a maximum effective range of about , beyond which it became too inaccurate to reliably strike a target. The mine is long out of production and no longer in US ...

High-explosive Anti-tank
High-explosive anti-tank (HEAT) is the effect of a shaped charge explosive that uses the Munroe effect to penetrate heavy armor. The warhead functions by having an explosive charge collapse a metal liner inside the warhead into a high-velocity shaped charge jet; this is capable of penetrating armor steel to a depth of seven or more times the diameter of the charge (charge diameters, CD). The shaped charge jet armor penetration effect is purely kinetic in nature; the round has no explosive or incendiary effect on the armor. Unlike standard armor piercing shell, armor-piercing rounds, a HEAT warhead's penetration performance is unaffected by the projectile's velocity, allowing them to be fired by lower-powered weapons that generate less recoil. The performance of HEAT weapons has nothing to do with heat, thermal effects, with HEAT being simply an acronym. History HEAT warheads were developed during World War II, from extensive research and development into shaped charge warh ...

Angolan Civil War
The Angolan Civil War () was a civil war in Angola, beginning in 1975 and continuing, with interludes, until 2002. The war began immediately after Angola became independent from Portugal in November 1975. It was a power struggle between two former anti-colonial guerrilla movements, the communist MPLA, People's Movement for the Liberation of Angola (MPLA) and the anti-communist UNITA, National Union for the Total Independence of Angola (UNITA). The MPLA and UNITA had different roots in Angolan society and mutually incompatible leaderships, despite their shared aim of ending colonial rule. A third movement, the National Front for the Liberation of Angola (FNLA), having fought the MPLA with UNITA during the Angolan War of Independence, played almost no role in the Civil War. Additionally, the Front for the Liberation of the Enclave of Cabinda (FLEC), an association of separatist militant groups, fought for the independence of the province of Cabinda (province), Cabinda from Angola. ...

Picatinny Arsenal
The Picatinny Arsenal ( or ) is an American military research and manufacturing facility located on of land in Jefferson and Rockaway Townships in Morris County, New Jersey, United States, encompassing Picatinny Lake and Lake Denmark. The Arsenal is the headquarters of the U.S. Army Combat Capabilities Development Command Armaments Center. It is known for developing the ubiquitous Picatinny rail, as well as being the Army's center of expertise for small arms cartridge ammunition. The facility was founded in 1880 as the ''Picatinny Powder Depot''. Soon afterward, the Navy acquired a portion of the arsenal to establish the Lake Denmark Powder Depot, later known as Lake Denmark Naval Ammunition Depot. It manufactured gunpowder until after World War I, at which time the facility also began producing heavy munitions and grew more involved in research and development activities. During World War II, Picatinny was a major large-caliber-round loading plant with 18,000 employees. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Composition B
Composition B (Comp B), also known as Hexotol and Hexolite (among others), is a high 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 Kingdom and United States.''Atom Bombs: The Top Secret Inside Story of Little Boy and Fat Man'', John Coster-Mullen, 2003Nuclear Weapons FAQ section 8.1.1: The Design of Gadget, Fat Man, and "Joe 1" (RDS-1) accessed August 10, 2009 The standard proportions of ingredients (by weight) are 59.5% RDX ( |
Off-route Mine
An anti-tank or 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, 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 British towards the end of the war. Initially they were nothing more than a buried high-explosive shell or 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 techniques, and mines accounted for 15% of U.S. tank casualties during the Battle of Saint-Mihiel, Third Battle of the ...

Land Mine
A land mine, or landmine, is an explosive weapon often concealed under or camouflaged on the ground, and designed to destroy or disable enemy targets as they pass over or near it. Land mines are divided into two types: anti-tank mines, which are designed to disable tanks or other vehicles; and anti-personnel mines, designed to injure or kill people. Land mines are typically pressure activated, exploding automatically when stepped on by a person or driven over by a vehicle, though alternative detonation mechanisms are sometimes used. A land mine may cause damage by direct blast effect, by fragments that are thrown by the blast, or by both. Land mines are typically laid throughout an area, creating a ''minefield'' which is dangerous to cross. The use of land mines is controversial because of their indiscriminate nature and their potential to remain dangerous many years after a conflict has ended, harming civilians and the economy. With pressure from a number of campaign gro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bazooka
The Bazooka () is a Man-portable anti-tank systems, man-portable recoilless Anti-tank warfare, anti-tank rocket launcher weapon, widely deployed by the United States Army, especially during World War II. Also referred to as the "stovepipe", the innovative Bazooka was among the first generation of rocket-propelled grenade, rocket-propelled anti-tank weapons used in infantry combat. Featuring a solid-propellant rocket for propulsion, it allowed for high-explosive anti-tank (HEAT) shaped charge warheads to be delivered against Vehicle armour, armored vehicles, machine gun nests, and fortified bunkers at ranges beyond that of a standard thrown grenade or land mine, mine. The universally applied nickname arose from the weapon's M1 variant's vague resemblance to the musical instrument called a ''Bazooka (instrument), bazooka'' invented and popularized by 1930s American comedian Bob Burns (humorist), Bob Burns. During World War II, the Nazi Germany, German armed forces captured severa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

List Of U
A list is a set of discrete items of information collected and set forth in some format for utility, entertainment, or other purposes. A list may be memorialized in any number of ways, including existing only in the mind of the list-maker, but lists are frequently written down on paper, or maintained electronically. Lists are "most frequently a tool", and "one does not ''read'' but only ''uses'' a list: one looks up the relevant information in it, but usually does not need to deal with it as a whole". Lucie Doležalová,The Potential and Limitations of Studying Lists, in Lucie Doležalová, ed., ''The Charm of a List: From the Sumerians to Computerised Data Processing'' (2009). Purpose It has been observed that, with a few exceptions, "the scholarship on lists remains fragmented". David Wallechinsky, a co-author of '' The Book of Lists'', described the attraction of lists as being "because we live in an era of overstimulation, especially in terms of information, and lists help ...

Anti-tank Mines
Anti-tank warfare refers to the military strategies, tactics, and weapon systems designed to counter and destroy enemy armored vehicles, particularly tanks. It originated during World War I following the first deployment of tanks in 1916, and has since become a fundamental component of land warfare doctrine. Over time, anti-tank warfare has evolved to include a wide range of systems, from handheld infantry weapons and anti-tank guns to guided missiles and air-delivered munitions. Anti-tank warfare evolved rapidly during World War II, leading to infantry-portable weapons. Through the Cold War of 1947–1991, the United States, anti-tank weapons have also been upgraded in number and performance. Since the end of the Cold War in 1992, new threats to tanks and other armored vehicles have included remotely detonated improvised explosive devices (IEDs). During the Russian invasion of Ukraine, drones and loitering munitions have attacked and destroyed tanks. Tank threat Ant ...

Tripwire Weapons
A tripwire is a passive triggering mechanism. Typically, a wire or cord is attached to a device for detecting or reacting to physical movement. Military applications Such tripwires may be attached to one or more minesespecially fragmentation or bounding minesin order to increase the area where triggering may occur. Trip wires are frequently used in booby trapswhere either a tug on the wire, or the release of tension on it, will trigger the explosives. Soldiers sometimes detect the presence of tripwires by spraying the area with Silly String. It will settle to the ground in areas where there are no wires; where wires are present, the "strings" will rest on the taut wires without triggering the explosive, due to the product's light weight. Its use in detecting tripwires was first discovered in 1993 by Sergeant First Class David B. Chandler, Chief Instructor of the United States Army's Sapper Leader Course. That year it was introduced to students attending the course ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
