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 explosively formed penetrator (EFP) 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 EFPs jet effect is purely kinetic in nature; the round has no explosive or incendiary effect on the target. Because they rely on the kinetic energy of the EFP jet for their penetration performance, HEAT warheads do not have to be delivered with high velocity, as an armor-piercing round does. Thus they generate less recoil. The performance of HEAT weapons has nothing to do with 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 warheads. Shaped char ...

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.''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 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, 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 ...

Land Mine
A land mine is an explosive device concealed under or on the ground and designed to destroy or disable enemy targets, ranging from combatants to vehicles and tanks, as they pass over or near it. Such a device is typically detonated automatically by way of pressure when a target steps on it or drives over it, although other detonation mechanisms are also sometimes used. A land mine may cause damage by direct blast effect, by fragments that are thrown by the blast, or by both. Landmines are typically laid throughout an area, creating a ''minefield'' which is dangerous to cross. The use of land mines is controversial because of their potential as indiscriminate weapons. They can remain dangerous many years after a conflict has ended, harming civilians and the economy. Seventy-eight countries are contaminated with land mines and 15,000–20,000 people are killed every year while many more are injured. Approximately 80% of land mine casualties are civilians, with children as the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bazooka
Bazooka () is the common name for 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 warhead, high-explosive anti-tank (HEAT) 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 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.

PARM 1 Mine
The PARM 1 (DM-12) and PARM 2 (DM-22) are German off-route mines that fire small fin stabilized rockets. ''PARM'' stands for ''PanzerAbwehrRichtMine'', anti-tank directional mine. 1600 DM-22 mines were delivered to Ukrainian armed services in early May 2022. Development The mine was developed in the early 1980s to meet the US MIL-STD-331A and US MIL-STD-810C requirements. Trials of the mine were conducted between March 1983 and March 1988. In June 1988 it was accepted into service with the Bundeswehr, with the Army receiving the first batch of 25,000 between 1991 and 1994. The PARM 2 was a development of PARM 1 incorporating an infra-red sensor and an improved rocket. PARM 1 The PARM 1 is mounted on a small tripod, allowing it to be traversed through 360 degrees, elevated to 90 degrees and depressed to −45 degrees. The mine is manually emplaced and incorporates an arming delay of five minutes. It can be detonated either by command or by a fibre optic trigger cable, which tri ...

TM-83 Mine
The TM-83 is a Soviet off-route shaped charge anti-tank mine, first shown publicly in 1993, and developed in 1983. The mine consists of a large Misznay Schardin effect warhead and is actived using its infra-red and seismic sensors. Deployment The mine can be installed on soil, or be attached to various objects only manually. The mine is generally positioned 5 meters from the road, and it is intended to attack and aimed using an integrated sight. The TM-83 can be deployed in two operation modes – autonomous or controlled. The primary difference is that the controlled version has a 100-meter-long wire attached, allowing the operator to switch it through its various modes repeatedly (safe or active, see ). If the mine is controlled, it can be switched to its safety mode and be easily removed; however, if the mine is in its autonomous mode, it is considered impossible to remove due to the high sensitivity of the seismic sensor and the chance that the mine will be set off by the ...

MPB Mine
The MPB is a Polish off-route anti-tank mine. It was developed by BELMA (BZE BELMA S.A.) with its partner Military Institute of Engineer Technology. The MPB consists of a metal cylinder filled with explosives, mounted horizontally in an adjustable frame. The mine is intended to be hidden from direct view of the intended target, off to the side of a probable vehicle route, usually a road, to attack the weaker armour on the sides and rear of a vehicle. The mine can be triggered by either a contact fuze (MPB-ZK variant) or an influence fuze (MPB-ZN variant) based on infrared and acoustic sensors, and is also fitted with an anti-handling device. When used with the passive infrared fuze, an acoustic sensor detects approaching vehicles and activates the infrared sensor, which triggers the mine at an optimal moment as the target passes. The mine can be programmed to self-destruct after either 1, 10 or 30 days have passed. The mine uses the Misznay–Schardin effect to project an explosi ...
