Hillbilly Armour
Improvised vehicle armour is protective materials added to a mobile platform such as a car, truck, or tank in an irregular and extemporized fashion, using available materials. Typically, improvised armour is added in the field and it was not originally part of the design, an official up-armour kit, nor centrally planned and distributed. Improvised armour is used to protect occupants from small arms, crew-served weapons and artillery (or tank) fire, and mines. Improvised additions have included metal plate, scrap metal, sandbags, concrete, wood, and, since at least the 2000s, Kevlar. These materials vary widely in their ballistic protection. Improvised vehicle armour has appeared on the battlefield for as long as vehicles have been used in combat. In WW I, the first armoured cars were made by adding metal plating to regular vehicles. In World War II, tank crews of many armies attached spare metal tracks to the hulls and turrets of their tanks. In the Vietnam War, U.S. "gun tru ...

Home Guard (United Kingdom)
The Home Guard (initially Local Defence Volunteers or LDV) was an armed citizen militia supporting the British Army during the Second World War. Operational from 1940 to 1944, the Home Guard had 1.5 million local volunteers otherwise ineligible for military service, such as those who were too young or too old to join the regular armed services (regular military service was restricted to those aged 18 to 41) and those in reserved occupations. Excluding those already in the armed services, the civilian police or civil defence, approximately one in five men were volunteers. Their role was to act as a secondary defence force in case of invasion by the forces of Nazi Germany. The Home Guard were to try to slow down the advance of the enemy even by a few hours to give the regular troops time to regroup. They were also to defend key communication points and factories in rear areas against possible capture by paratroops or fifth columnists. A key purpose was to maintain control of the c ...

Shaped Charge
A shaped charge is an explosive charge shaped to form an explosively formed penetrator (EFP) to focus the effect of the explosive's energy. Different types of shaped charges are used for various purposes such as cutting and forming metal, initiating nuclear weapons, penetrating armor, or perforating wells in the oil and gas industry. A typical modern shaped charge, with a metal liner on the charge cavity, can penetrate armor steel to a depth of seven or more times the diameter of the charge (charge diameters, CD), though greater depths of 10 CD and above have been achieved. Contrary to a misconception (possibly resulting from the acronym for ''high-explosive anti-tank'', HEAT) the shaped charge EFP jet does not depend in any way on heating or melting for its effectiveness; that is, the EFP jet from a shaped charge does not melt its way through armor, as its effect is purely kinetic in nature – however the process does create significant heat and often has a significant ...

Stuart Tank
The M3 Stuart/Light Tank M3, was an American light tank of World War II. An improved version of the tank entered service as the M5 in 1942 to be supplied to British and other Commonwealth forces under lend-lease prior to the entry of the U.S. into the war. Afterwards, it was used by U.S. and Allied forces until the end of the war. The British service name "Stuart" came from the American Civil War Confederate general J. E. B. Stuart and was used for both the M3 and the derivative M5 Light Tank. Unofficially, were also often called "Honeys" by the British, because of their smooth ride. In U.S. use, the tanks were officially known as "Light Tank M3" and "Light Tank M5". Stuarts were first used in combat in the North African campaign; about 170 were used by the British forces in Operation Crusader (18 November – 30 December 1941). Stuarts were the first American-crewed tanks in World War II to engage the enemy in tank versus tank combat when used in the Philippines in Decem ...

M4 Sherman
} The M4 Sherman, officially Medium Tank, M4, was the most widely used medium tank by the Military history of the United States during World War II, United States and Allies of World War II, Western Allies in World War II. The M4 Sherman proved to be reliable, relatively cheap to produce, and available in great numbers. It was also the basis of several other Armoured_fighting_vehicle, armored fighting vehicles including self-propelled artillery, Tank_destroyer, tank destroyers, and Armoured_recovery_vehicle, armored recovery vehicles. Tens of thousands were distributed through the Lend-Lease program to the British Empire#Second World War, British Commonwealth and Soviet Union. The tank was named by the British after the American Civil War General William Tecumseh Sherman. The M4 Sherman evolved from the M3 Lee, M3 Medium Tank, which for speed of development had its main armament in a side sponson mount. The M4 retained much of the previous mechanical design, but moved the 75_mm ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Panzer
This article deals with the tanks (german: panzer) serving in the German Army (''Deutsches Heer'') throughout history, such as the World War I tanks of the Imperial German Army, the interwar and World War II tanks of the Nazi German Wehrmacht, the Cold War tanks of the West German and East German Armies, all the way to the present day tanks of the Bundeswehr. Overview The development of tanks in World War I began as an attempt to break the stalemate which trench warfare had brought to the Western Front. The British and French both began experimenting in 1915, and deployed tanks in battle from 1916 and 1917 respectively. The Germans, on the other hand, were slower to develop tanks, concentrating on anti-tank weapons. The German response to the modest initial successes of the Allied tanks was the A7V, which, like some other tanks of the period, was based on caterpillar tracks of the type found on the American Holt Tractors. Initially unconvinced that tanks were a serious thr ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Magnetic Mine
A naval mine is a self-contained explosive device placed in water to damage or destroy surface ships or submarines. Unlike depth charges, mines are deposited and left to wait until they are triggered by the approach of, or contact with, any vessel or a particular vessel type, akin to anti-infantry vs. anti-vehicle mines. Naval mines can be used offensively, to hamper enemy shipping movements or lock vessels into a harbour; or defensively, to protect friendly vessels and create "safe" zones. Mines allow the minelaying force commander to concentrate warships or defensive assets in mine-free areas giving the adversary three choices: undertake an expensive and time-consuming minesweeping effort, accept the casualties of challenging the minefield, or use the unmined waters where the greatest concentration of enemy firepower will be encountered. Although international law requires signatory nations to declare mined areas, precise locations remain secret; and non-complying individuals ...

Slat Armour
Slat armor (or slat armour in British English), also known as bar armor, cage armor, and standoff armor, is a type of vehicle armor designed to protect against high-explosive anti-tank (HEAT) attacks, as used by anti-tank guided missiles (ATGMs) and rocket-propelled grenades (RPGs). Operation Slat armor takes the form of a rigid slatted metal grid fitted around key sections of the vehicle, which disrupts the shaped charge of the warhead by either crushing it, preventing optimal detonation from occurring, or by damaging the fuzing mechanism, preventing detonation outright. Although slat armor is effective against incoming missiles, it does not offer complete protection – as many as 50% of missile impacts are unimpeded by the slat design. Slat armor is more likely to be effective if the cage spacing is less than the diameter of the incoming RPG round, which is commonly 85 mm. Combat history World War II The German Wehrmacht was the first employer of cage armor duri ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Spaced Armour
Armour with two or more plates spaced a distance apart falls under the category of spaced armour. Spaced armour can be sloped or unsloped. When sloped, it reduces the penetrating power of bullets and solid shot, as after penetrating each plate projectiles tend to tumble, deflect, deform, or disintegrate; spaced armour that is not sloped is generally designed to provide protection from explosive projectiles, which detonate before reaching the primary armour. Spaced armour is used on military vehicles such as tanks and combat bulldozers. In a less common application, it is used in some spacecraft that use Whipple shields. Against kinetic penetrators The first spaced armour was used on iron and steel Battleship, warships from the mid-19th century. Between the thin outer armour of various less important parts and the thick main armour (protecting turrets, ammunition depots, boilers and turbines) were constructed storage spaces, coal or oil bunkers, and so on (Lord Nelson-class batt ...

Antitank Weapon
Anti-tank warfare originated from the need to develop technology and tactics to destroy tanks during World War I. Since the Triple Entente deployed the first tanks in 1916, the German Empire developed the first anti-tank weapons. The first developed anti-tank weapon was a scaled-up bolt-action rifle, the Mauser 1918 T-Gewehr, that fired a 13mm cartridge with a solid bullet that could penetrate the thin armor of tanks of the time and destroy the engine or ricochet inside, killing occupants. Because tanks represent an enemy's strong force projection on land, military strategists have incorporated anti-tank warfare into the doctrine of nearly every combat service since. The most predominant anti-tank weapons at the start of World War II in 1939 included the tank-mounted gun, anti-tank guns and anti-tank grenades used by the infantry, and ground-attack aircraft. Anti-tank warfare evolved rapidly during World War II, leading to the inclusion of infantry-portable weapons such as th ...

Arms Race
An arms race occurs when two or more groups compete in military superiority. It consists of a competition between two or more states to have superior armed forces; a competition concerning production of weapons, the growth of a military, and the aim of superior military technology, the term is also used to describe any long-term escalating competitive situation where each competitor or competitive group focuses on out-doing others. Unlike a sporting race, which constitutes a specific event with winning interpretable as the outcome of a singular project, arms races constitute spiralling systems of on-going and potentially open-ended behavior. The existing scholarly literature is divided as to whether arms races correlate with war. International-relations scholars explain arms races in terms of the security dilemma, rationalist spiral models, states with revisionist aims, and deterrence models.
