Type 92 Heavy Machine Gun
was a Japanese heavy machine gun, related to the Hotchkiss machine gun series. It entered service in 1932 and was the standard Japanese heavy machine gun used during World War II. Known for its reliability, it was used after the war by various forces in East Asia. Designed by Kijiro Nambu and built by Hino Motors and Hitachi, its total production was about 45,000 guns. The Type 92 refers to the Japanese Imperial year 2592 – 1932 in the Gregorian calendar – in which the gun entered service. Design The Type 92 was essentially a scaled-up version of the Type 3 heavy machine gun, with its calibre increased to 7.7 mm, and like the Type 3 was air cooled, ammo strip-fed, and based on the Hotchkiss M1914. It could use both a rimless and semi-rimmed 7.7x58mm Shiki round. A 7.7mm Arisaka round could be used if necessary or if other ammunition supplies dwindled. Rounds fired from the gun traveled at about , and the rate of fire was about 450 rpm. It was sometimes used as a ligh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heavy Machine Gun
A heavy machine gun (HMG) is significantly larger than light, medium or general-purpose machine guns. HMGs are typically too heavy to be man-portable (carried by one person) and require mounting onto a weapons platform to be operably stable or tactically mobile, have more formidable firepower, and generally require a team of personnel for operation and maintenance. There are two generally recognized classes of weapons identified as HMGs. The first are weapons from World War I identified as "heavy" due to the weight and cumbersomeness of the weapons themselves, which prevents infantrymen from transporting on foot, such as the M1917 Browning machine gun. The second are large-caliber ( 12.7×99mm, 12.7×108mm, 14.5×114mm, or larger) machine guns, pioneered by John Browning with the M2 machine gun, designed to provide increased effective range, penetration and destructive power against covers, vehicles, aircraft and light buildings/fortifications beyond the standard-caliber ...

Hino Motors
Hino Motors, Ltd., commonly known as Hino, is a Japanese manufacturer of commercial vehicles and diesel engines (including those for trucks, buses and other vehicles) headquartered in Hino, Tokyo. The company was established in 1942 as a corporate spin-off from previous manufacturers. Hino Motors is a large constituent of the Nikkei 225 on the Tokyo Stock Exchange. It is a subsidiary of Toyota Motor Corporation and one of 16 major companies of the Toyota Group. History The company traces its roots back to the founding of Tokyo Gas Industry Company in 1910. In 1910, Chiyoda Gas Company was established and competed fiercely against incumbent Tokyo Gas Company for gas lighting users. Tokyo Gas Industry was a parts supplier for Chiyoda Gas but it was defeated and merged into Tokyo Gas in 1912. Having lost its largest client, Tokyo Gas Industry Co. broadened its product line including electronic parts, and renamed itself as Tokyo Gas and Electric Industry (東京瓦斯電気 ...

Imperial Japanese Army
The was the official ground-based armed force of the Empire of Japan from 1868 to 1945. It was controlled by the Imperial Japanese Army General Staff Office and the Ministry of the Army, both of which were nominally subordinate to the Emperor of Japan as supreme commander of the army and the Imperial Japanese Navy. Later an Inspectorate General of Aviation became the third agency with oversight of the army. During wartime or national emergencies, the nominal command functions of the emperor would be centralized in an Imperial General Headquarters (IGHQ), an ad hoc body consisting of the chief and vice chief of the Army General Staff, the Minister of the Army, the chief and vice chief of the Naval General Staff, the Inspector General of Aviation, and the Inspector General of Military Training. History Origins (1868–1871) In the mid-19th century, Japan had no unified national army and the country was made up of feudal domains (''han'') with the Tokugawa shogunate (''bakufu ...

Telescopic Sight
A telescopic sight, commonly called a scope informally, is an optical sighting device based on a refracting telescope. It is equipped with some form of a referencing pattern – known as a '' reticle'' – mounted in a focally appropriate position in its optical system to provide an accurate point of aim. Telescopic sights are used with all types of systems that require magnification in addition to reliable visual aiming, as opposed to non-magnifying iron sights, reflector (reflex) sights, holographic sights or laser sights, and are most commonly found on long-barrel firearms, particularly rifles, usually via a scope mount. The optical components may be combined with optoelectronics to add night vision or smart device features. History The first experiments directed to give shooters optical aiming aids go back to the early 17th century. For centuries, different optical aiming aids and primitive predecessors of telescopic sights were created that had practica ...

Periscope
A periscope is an instrument for observation over, around or through an object, obstacle or condition that prevents direct line-of-sight observation from an observer's current position. In its simplest form, it consists of an outer case with mirrors at each end set parallel to each other at a 45° angle. This form of periscope, with the addition of two simple lenses, served for observation purposes in the trenches during World War I. Military personnel also use periscopes in some gun turrets and in armoured vehicles. More complex periscopes using prisms or advanced fiber optics instead of mirrors and providing magnification operate on submarines and in various fields of science. The overall design of the classical submarine periscope is very simple: two telescopes pointed into each other. If the two telescopes have different individual magnification, the difference between them causes an overall magnification or reduction. Early examples Johannes Hevelius described an earl ...

Allies Of World War II
The Allies, formally referred to as the United Nations from 1942, were an international military coalition formed during the Second World War (1939–1945) to oppose the Axis powers, led by Nazi Germany, Imperial Japan, and Fascist Italy. Its principal members by 1941 were the United Kingdom, United States, Soviet Union, and 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, France, and Poland, as well as their respective dependencies, such as British India. They were soon joined by the independent dominions of the British Commonwealth: Canada, Australia, New Zealand and South Africa. Consequently, the initial alliance resembled that of the First World War. As Axis forces began invading northern Europe and the Balkans, the Allies added the Netherlands, Belgium, Norway, Greece, and Yugoslavia. The Soviet Union, which initially had a nonaggression pa ...

Woodpecker
Woodpeckers are part of the bird family Picidae, which also includes the piculets, wrynecks, and sapsuckers. Members of this family are found worldwide, except for Australia, New Guinea, New Zealand, Madagascar, and the extreme polar regions. Most species live in forests or woodland habitats, although a few species are known that live in treeless areas, such as rocky hillsides and deserts, and the Gila woodpecker specialises in exploiting cacti. Members of this family are chiefly known for their characteristic behaviour. They mostly forage for insect prey on the trunks and branches of trees, and often communicate by drumming with their beaks, producing a reverberatory sound that can be heard at some distance. Some species vary their diet with fruits, birds' eggs, small animals, tree sap, human scraps, and carrion. They usually nest and roost in holes that they excavate in tree trunks, and their abandoned holes are of importance to other cavity-nesting birds. They sometimes com ...

Pacific War
The Pacific War, sometimes called the Asia–Pacific War, was the theater of World War II that was fought in Asia, the Pacific Ocean, the Indian Ocean, and Oceania. It was geographically the largest theater of the war, including the vast Pacific Ocean theater, the South West Pacific theater, the Second Sino-Japanese War, and the Soviet–Japanese War. The Second Sino-Japanese War between the Empire of Japan and the Republic of China had been in progress since 7 July 1937, with hostilities dating back as far as 19 September 1931 with the Japanese invasion of Manchuria. However, it is more widely accepted that the Pacific War itself began on 7 December (8 December Japanese time) 1941, when the Japanese simultaneously invaded Thailand, attacked the British colonies of Malaya, Singapore, and Hong Kong as well as the United States military and naval bases in Hawaii, Wake Island, Guam, and the Philippines. The Pacific War saw the Allies pitted against Japan, the la ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anti-aircraft Warfare
Anti-aircraft warfare, counter-air or air defence forces is the battlespace response to aerial warfare, defined by NATO as "all measures designed to nullify or reduce the effectiveness of hostile air action".AAP-6 It includes surface based, subsurface ( submarine launched), and air-based weapon systems, associated sensor systems, command and control arrangements, and passive measures (e.g. barrage balloons). It may be used to protect naval, ground, and air forces in any location. However, for most countries, the main effort has tended to be homeland defence. NATO refers to airborne air defence as counter-air and naval air defence as anti-aircraft warfare. Missile defence is an extension of air defence, as are initiatives to adapt air defence to the task of intercepting any projectile in flight. In some countries, such as Britain and Germany during the Second World War, the Soviet Union, and modern NATO and the United States, ground-based air defence and air defence aircraft ...

Hotchkiss M1914
The Mle 1914 Hotchkiss machine gun chambered for the 8mm Lebel cartridge became the standard machine gun of the French Army during the latter half of World War I. It was manufactured by the French arms company Hotchkiss et Cie, which had been established in the 1860s by American industrialist Benjamin B. Hotchkiss. The gas-actuated Hotchkiss system was first formulated in 1893 by Odkolek von Ujezda and improved into its final form by Hotchkiss armament engineers, American Laurence Benét and his French assistant Henri Mercié. The Mle 1914 was the last version of a series of nearly identical Hotchkiss designs : the Mle 1897, Mle 1900 and the Mle 1909. The Hotchkiss Mle 1914 became the French infantry standard in late 1917, replacing the unreliable St. Étienne Mle 1907. The American Expeditionary Forces (AEF) in France also purchased 7,000 Mle 1914 Hotchkiss machine guns in 8mm Lebel, and used them extensively at the front in 1917 and 1918.

Caliber
In guns, particularly firearms, caliber (or calibre; sometimes abbreviated as "cal") is the specified nominal internal diameter of the gun barrel bore – regardless of how or where the bore is measured and whether the finished bore matches that specification. It is measured in inches or in millimeters. In the United States it is expressed in hundredths of an inch; in the United Kingdom in thousandths; and elsewhere in millimeters. For example, a "45 caliber" firearm has a barrel diameter of roughly . Barrel diameters can also be expressed using metric dimensions. For example, a "9 mm pistol" has a barrel diameter of about 9 millimeters. Since metric and US customary units do not convert evenly at this scale, metric conversions of caliber measured in decimal inches are typically approximations of the precise specifications in non-metric units, and vice versa. In a rifled barrel, the distance is measured between opposing lands or between opposing grooves; groove mea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Type 3 Heavy Machine Gun
, also known as the Taishō 14 machine gun, was a Japanese air-cooled heavy machine gun. Design The Type 3 heavy machine gun was based on the design of the Hotchkiss M1914. Although the Hotchkiss used 8mm cartridges, from 1914 Japan produced the Type 3 under license from Hotchkiss using the 6.5x50mm Arisaka ammunition. It used an ammo strip for loading rounds. Its tripod could be used as an anti-aircraft mounting, and special anti-aircraft sights were provided. Users * : Chile bought several hundred Type 3 machine guns in 7×57mm Mauser as ''Modelo 1920''. Barrels were manufactured in France by Hotchkiss but most of the weapon was made at the Kokura arsenal. * : Purchased for Chang Tso-lin's Fengtian Army. Later used by the Collaborationist Chinese Army * * * : It was used by the Korean People's Army during the Korean War. * Gallery Japanese Type 92 Heavy Machine Gun (9885155276).jpg, A Type 3 and Type 92 next to each other at a Beijing museum, showing the similarity ...
