High-explosive Dual-purpose
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 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 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 charge warheads ...

Detonation
Detonation () is a type of combustion involving a supersonic exothermic front accelerating through a medium that eventually drives a shock front propagating directly in front of it. Detonations propagate supersonically through shock waves with speeds about 1 km/sec and differ from deflagrations which have subsonic flame speeds about 1 m/sec. Detonation may form from an explosion of fuel-oxidizer mixture. Compared with deflagration, detonation doesn't need to have an external oxidizer. Oxidizers and fuel mix when deflagration occurs. Detonation is more destructive than deflagrations. In detonation, the flame front travels through the air-fuel faster than sound; while in deflagration, the flame front travels through the air-fuel slower than sound. Detonations occur in both conventional solid and liquid explosives, as well as in reactive gases. TNT, dynamite, and C4 are examples of high power explosives that detonate. The detonation velocity, velocity of detonation in solid an ...

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 ...

Spigot Mortar
A mortar today is usually a simple, lightweight, man-portable, muzzle-loaded cannon, consisting of a smooth-bore (although some models use a rifled barrel) metal tube fixed to a base plate (to spread out the recoil) with a lightweight bipod mount and a sight. Mortars are typically used as indirect fire weapons for close fire support with a variety of ammunition. Historically mortars were heavy siege artillery. Mortars launch explosive shells (technically called bombs) in high arching ballistic trajectories. History Mortars have been used for hundreds of years. The earliest reported use of mortars was in Korea in a 1413 naval battle when Korean gunsmiths developed the ''wan'gu'' (gourd-shaped mortar) (완구, 碗口). The earliest version of the ''wan'gu'' dates back to 1407. Ch'oe Hae-san (1380–1443), the son of Ch'oe Mu-sŏn (1325–1395), is generally credited with inventing the ''wan'gu''. In the Ming dynasty, general Qi Jiguang recorded the use of a mini cannon ...

Battleship
A battleship is a large, heavily naval armour, armored warship with a main battery consisting of large naval gun, guns, designed to serve as a capital ship. From their advent in the late 1880s, battleships were among the largest and most formidable weapon systems ever built, until they were surpassed by aircraft carriers beginning in the 1940s. The modern battleship traces its origin to the sailing ship of the line, which was developed into the steam ship of the line and soon thereafter the ironclad warship. After a period of extensive experimentation in the 1870s and 1880s, ironclad design was largely standardized by the British , which are usually referred to as the first "pre-dreadnought battleships". These ships carried an armament that usually included four large guns and several medium-caliber guns that were to be used against enemy battleships, and numerous small guns for self-defense. Naval powers around the world built dozens of pre-dreadnoughts in the 1890s and early ...

Mistel
''Mistel'' (German language, German, 'mistletoe', a parasitic plant) was the larger, unmanned component of a composite aircraft configuration developed in Germany during the later stages of World War II. The composite comprised a small piloted control aircraft mounted above a large explosives-carrying drone, the , and as a whole was referred to as the ''Huckepack'' ('Piggyback'), also known as the ''Beethoven-Gerät'' ('Beethoven Device') or ''Vati und Sohn'' ('Daddy and Son'). The most successful of these used a modified Junkers Ju 88 bomber as the ''Mistel'', with the entire nose-located crew compartment replaced by a specially designed nose filled with a large load of explosives, formed into a shaped charge. The upper component was a fighter aircraft, joined to the by struts. The combination would be flown to its target by a pilot in the fighter; then the unmanned bomber was released to hit its target and explode, leaving the fighter free to return to base. The first such c ...

PIAT
The Projector, Infantry, Anti Tank (PIAT) Mk I was a British man-portable anti-tank weapon developed during the Second World War. The PIAT was designed in 1942 in response to the British Army's need for a more effective infantry anti-tank weapon and entered service in 1943. The PIAT was based on the spigot mortar system, and projected (launched) a 2.5 pound (1.1 kg) shaped charge bomb using a cartridge in the tail of the projectile. It possessed an effective range of approximately in a direct fire anti-tank role, and in an indirect fire role. The PIAT had several advantages over other infantry anti-tank weapons of the period: it had greatly increased penetration power over the previous anti-tank rifles, it had no back-blast which might reveal the position of the user or accidentally injure friendly soldiers around the user, and it was simple in construction. However, the device also had some disadvantages: powerful recoil, a difficulty in cocking the weapon, and early pro ...

Bundesarchiv Bild 101I-671-7483-29, Reichsgebiet, Soldat Mit Panzerabwehrwaffe
The German Federal Archives or Bundesarchiv (BArch) (, lit. "Federal Archive") are the national archives of Germany. They were established at the current location in Koblenz in 1952. They are subordinated to the Federal Commissioner for Culture and the Media (Claudia Roth since 2021) under the German Chancellery, and before 1998, to the Federal Ministry of the Interior. On 6 December 2008, the Archives donated 100,000 photos to the public, by making them accessible via Wikimedia Commons. History The federal archive for institutions and authorities in Germany, the first precursor to the present-day Federal Archives, was established in Potsdam, Brandenburg in 1919, a later date than in other European countries. This national archive documented German government dating from the founding of the North German Confederation in 1867. It also included material from the older German Confederation and the Imperial Chamber Court. The oldest documents in this collection dated back to the ...

Panzerfaust
The (, or , plural: ) was a development family of single-shot man-portable anti-tank systems developed by Nazi Germany during World War II. The weapons were the first single-use light anti-tank weapons based on a pre-loaded disposable launch tube, a weapon configuration which is still used today (a contemporary example being the 84mm AT4). The -design consisted of a light recoilless launcher tube outfitted with a single pre-loaded high-explosive anti-tank warhead protruding from the muzzle. It was an inexpensive, easy-to-use anti-tank weapon for the common infantry man, being issued as a single unit of ammunition meant to be operated by a single soldier. Firing was done from under the arm at an upward angle as the effective firing range was barely beyond that of hand grenades ( max). After use the launcher was discarded. Development of the started in 1942. The initial design was dubbed ( "fist-cartridge") and was smaller than the later designs. Later dubbed ("tank-f ...

Panzerschreck
''Panzerschreck'' ( "tank's dread" or "tank's bane") was the popular name for the ''Raketenpanzerbüchse'' 54 ("Rocket Anti-armor Rifle Model 54", abbreviated to RPzB 54), an 88 mm reusable anti-tank rocket launcher developed by Nazi Germany in World War II. Another earlier, official name was ''Ofenrohr'' ("stove pipe"). The ''Panzerschreck'' was designed as a lightweight infantry anti-tank weapon and was an enlarged copy of the American bazooka. The weapon was shoulder-launched and fired a fin-stabilized rocket with a shaped-charge warhead. It was made in smaller numbers than the '' Panzerfaust'', which was a light, disposable anti-tank weapon that used a system akin to recoilless rifles. History The ''Panzerschreck'' development was initially based on the American "bazooka", captured during the Tunisian campaign, November 1942. The ''Panzerschreck'' was larger and heavier than its American counterpart – the ''Panzerschreck'' had an 88 mm calibre, compared to ...

Paratrooper
A paratrooper or military parachutist is a soldier trained to conduct military operations by parachuting directly into an area of operations, usually as part of a large airborne forces unit. Traditionally paratroopers fight only as light infantry armed with small arms and light weapons, although some paratroopers can also function as artillerymen or mechanized infantry by utilizing field guns, infantry fighting vehicles and light tanks that are often used in surprise attacks to seize strategic positions behind enemy lines such as airfields, bridges and major roads. Overview Paratroopers jump out of aircraft and use parachutes to land safely on the ground. This is one of the three types of "forced entry" strategic techniques for entering a theater (warfare), theater of war; the other two being by land and by water. Their tactical advantage of entering the battlefield from the air is that they can attack areas not directly accessible by other transport. The ability of airbo ...
