Type 3 Grenade
The Type 3 "anti-tank" hand grenade is a Japanese grenade produced from 1943 to 1945 during World War II. It was designed to destroy the Allies' tanks. There are three variants (sub-types) of the weapon: ''Ko'' (Type A), ''Otsu'' (Type B), and ''Hei'' (Type C). History Throughout World War II, the U.S bombings gradually degraded the Japanese munition manufacturing base. Manufacturers were soon forced to find new, inexpensive and creative ways to produce grenades. Contrary to the Russians or Germans, the heavy armour threat was not very present, thus explaining the late development of the hollow charge. The Type 3 had a simplistic design and was made from expendable materials. This made the weapon relatively easy to produce. Examples of this Japanese grenade are extremely hard to find today. Design The Type 3 grenade had a tear drop-like shape. It consisted of a thin steel or aluminium cone mounted on a wooden head. The purpose of the head was to provide the correct stand-off ...

Anti-tank Grenade
An anti-tank grenade is a specialized hand-thrown grenade used to defeat armored targets. Although their inherently short range limits the usefulness of grenades, troops can lie in ambush or maneuver under cover to exploit the limited outward visibility of the crew in a target vehicle. Hand launched anti-tank grenades became redundant with the introduction of standoff rocket propelled grenades and man-portable anti-tank systems. Grenades were first used against armored vehicles during World War I, but it wasn't until World War II when more effective shaped charge anti-tank grenades were produced. AT grenades are unable to penetrate the armor of modern tanks, but may still damage lighter vehicles. History The first anti-tank grenades were improvised devices. During World War I the Germans were the first to come up with an improvised anti-tank grenade by taking their regular "potato masher" stick grenade and taping two or three more high explosive heads to create one larger gre ...

Imperial Japanese Army
The Imperial Japanese Army (IJA; , ''Dai-Nippon Teikoku Rikugun'', "Army of the Greater Japanese Empire") was the principal ground force of the Empire of Japan from 1871 to 1945. It played a central role in Japan’s rapid modernization during the Meiji period, fought in numerous conflicts including the First Sino-Japanese War, the Russo-Japanese War, World War I, the Second Sino-Japanese War, and World War II, and became a dominant force in Japanese politics. Initially formed from domain armies after the Meiji Restoration, it evolved into a powerful modern military influenced by French and German models. The IJA was responsible for several overseas military campaigns, including the invasion of Manchuria, involvement in the Boxer Rebellion, and fighting across the Asia-Pacific during the Pacific War. Notorious for committing widespread Japanese war crimes, war crimes, the army was dissolved after Japan's surrender in 1945, and its functions were succeeded by the Japan Ground Self-D ...

World War II
World War II or the Second World War (1 September 1939 – 2 September 1945) was a World war, global conflict between two coalitions: the Allies of World War II, Allies and the Axis powers. World War II by country, Nearly all of the world's countries participated, with many nations mobilising all resources in pursuit of total war. Tanks in World War II, Tanks and Air warfare of World War II, aircraft played major roles, enabling the strategic bombing of cities and delivery of the Atomic bombings of Hiroshima and Nagasaki, first and only nuclear weapons ever used in war. World War II is the List of wars by death toll, deadliest conflict in history, causing World War II casualties, the death of 70 to 85 million people, more than half of whom were civilians. Millions died in genocides, including the Holocaust, and by massacres, starvation, and disease.

Allies Of World War II
The Allies, formally referred to as the United Nations from 1942, were an international Coalition#Military, military coalition formed during World War II (1939–1945) to oppose the Axis powers. Its principal members were the "Four Policemen, Big Four" – the United Kingdom, United States, Soviet Union, and Republic of China (1912–1949), China. Membership in the Allies varied during the course of the war. When the conflict broke out on 1 September 1939, the Allied coalition consisted of the United Kingdom, French Third Republic, France, and Second Polish Republic, Poland, as well as their respective Dependent territory, dependencies, such as British Raj, British India. They were joined by the independent dominions of the British Commonwealth: Canada, Australia, Dominion of New Zealand, New Zealand and Union of South Africa, South Africa. Consequently, the initial alliance resembled Allies of World War I, that of the First World War. As Axis forces began German invasion of ...

Hollow Charge
A shaped charge, commonly also hollow charge if shaped with a cavity, is an explosive charge shaped 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 depths of 10 CD and above have been achieved. Contrary to a misconception, possibly resulting from the acronym ''HEAT'' (high-explosive anti-tank), the shaped charge does not depend in any way on heating or melting for its effectiveness; that is, the jet from a shaped charge does not melt its way through armor, as its effect is purely kinetic in nature—however the process creates significant heat and often has a significant secondary incendiary ef ...

Type 99 Mine
The Type 99 (Hako-Baku-Rai) mine was a Japanese anti-tank weapon used during the Second World War. It entered service in 1939. Four magnets were attached to the casing made of hemp cloth, along with an external fuze. The fuze had a time delay, which enabled it to be used as an anti-tank hand grenade, or a demolition charge. Once the safety pin was removed, it was armed, striking the fuze ignited a powder delay train. The mine detonated 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 ... after a five to ten seconds delay, giving enough time for it to be thrown. The mines could be stacked, held together by the magnets for greater effect. When used individually the mine could penetrate approximately 0.75 inches (19 mm) of steel, with two mines stacked it can penetrate 1.25 inches ( ...

2,4,6-Trinitroaniline
2,4,6-Trinitroaniline, C6H4N4O6, abbreviated as TNA and also known as picramide, a nitrated amine. Materials in this group range from slight to strong oxidizing agents. If mixed with reducing agents, including hydrides, sulfides and nitrides, they may begin a vigorous reaction that culminates in a detonation. The aromatic nitro compounds may explode in the presence of a base such as sodium hydroxide or potassium hydroxide even in the presence of water or organic solvents. The explosive tendencies of aromatic nitro compounds are increased by the presence of multiple nitro groups. The appearance of trinitroaniline varies from yellow to orange to red depending on its purity and concentration. Applications Trinitroaniline is only used in modern times in the small warheads of some explosive devices such as mortars. In World War II it was used by Imperial Japanese Navy as Type 97 ''bakuyaku'' (Model 1931 explosive) in some versions of gun projectiles instead of less stable burster ''sch ...

PETN
Pentaerythritol tetranitrate (PETN), also known as PENT, pentyl, PENTA (''ПЕНТА'', primarily in Russian), TEN (tetraeritrit nitrate), corpent, or penthrite (or, rarely and primarily in German, as ''nitropenta''), is an explosive material. It is the nitrate ester of pentaerythritol, and is structurally very similar to nitroglycerin. Penta refers to the five carbon atoms of the neopentane skeleton. PETN is a very powerful explosive material with a relative effectiveness factor of 1.66. When mixed with a plasticizer, PETN forms a plastic explosive. Along with RDX it is the main ingredient of Semtex. PETN is also used as a vasodilator drug to treat certain heart conditions, such as for management of angina. History Pentaerythritol tetranitrate was first prepared and patented in 1894 by the explosives manufacturer of Cologne, Germany. The production of PETN started in 1912, when the improved method of production was patented by the German government. PETN was used by ...

Picric Acid
Picric acid is an organic compound with the formula (O2N)3C6H2OH. Its IUPAC name is 2,4,6-trinitrophenol (TNP). The name "picric" comes from (''pikros''), meaning "bitter", due to its bitter taste. It is one of the most acidic phenols. Like other strongly nitrated organic compounds, picric acid is an explosive, which is its primary use. It has also been used as medicine (antiseptic, burn treatments) and as a dye. History Picric acid was probably first mentioned in the 17th-century alchemical writings of Johann Rudolf Glauber. Initially, it was made by nitrating substances such as animal horn, silk, indigo, and natural resin, the synthesis from indigo first being performed by Peter Woulfe in 1771. The German chemist Justus von Liebig had named picric acid (rendered in French as ). Picric acid was given that name by the French chemist Jean-Baptiste Dumas in 1841. Its synthesis from phenol, and the correct determination of its formula, were accomplished during 1841. In 1799 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
World War II Infantry Weapons Of Japan
The world is the totality of entities, the whole of reality, or everything that exists. The nature of the world has been conceptualized differently in different fields. Some conceptions see the world as unique, while others talk of a "plurality of worlds". Some treat the world as one simple object, while others analyze the world as a complex made up of parts. In scientific cosmology, the world or universe is commonly defined as "the totality of all space and time; all that is, has been, and will be". Theories of modality talk of possible worlds as complete and consistent ways how things could have been. Phenomenology, starting from the horizon of co-given objects present in the periphery of every experience, defines the world as the biggest horizon, or the "horizon of all horizons". In philosophy of mind, the world is contrasted with the mind as that which is represented by the mind. Theology conceptualizes the world in relation to God, for example, as God's creation, ...
