Howa Type 64
The , is a Japanese battle rifle used exclusively by the Japan Self-Defense Forces and the Japanese Coast Guard. It is a gas-operated, selective fire weapon which is chambered for the 7.62×51mm NATO round and uses a detachable 20-round box magazine. The Type 64 has never been exported due to Japan's strict anti-hardware export laws. It has been superseded by the more advanced Howa Type 89 from 1989 to 1990, but is still in service with all branches of the Self-Defense Forces and the Japanese Coast Guard. A small number of Howa Type 64 marksman versions have been used by the Special Armed Police unit. History Roughly a decade after the creation of the Japanese Self Defense Forces, the Defense Agency decided to make a domestically designed and manufactured main battle rifle to replace the aging M1 Garand rifles that had been given to them by the United States. It was developed by Howa Heavy Industries and eventually was produced in large numbers beginning in 1964 under the di ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anti-tank Guided Missile
An anti-tank guided missile (ATGM), anti-tank missile, anti-tank guided weapon (ATGW) or anti-armor guided weapon is a guided missile primarily designed to hit and destroy heavily armored military vehicles. ATGMs range in size from shoulder-launched weapons, which can be transported by a single soldier, to larger tripod-mounted weapons, which require a squad or team to transport and fire, to vehicle and aircraft mounted missile systems. Earlier man-portable anti-tank weapons like anti-tank rifles and magnetic anti-tank mines, generally had very short range, sometimes on the order of metres or tens of metres. Rocket-propelled high-explosive anti-tank (HEAT) systems appeared in World War II and extended range to the order of hundreds of metres, but accuracy was low and hitting targets at these ranges was largely a matter of luck. It was the combination of rocket propulsion and remote wire guidance that made the ATGM much more effective than these earlier weapons, and gave lig ...

M14 Rifle
The M14 rifle, officially the United States Rifle, Caliber 7.62 mm, M14, is an American selective fire battle rifle chambered for the 7.62×51mm NATO (.308 in) cartridge. It became the standard-issue rifle for the U.S. military in 1959, replacing the M1 Garand rifle in service with the U.S. Army by 1958 and the U.S. Marine Corps by 1965. The M14 was used by the U.S. Army, Navy, and Marine Corps for Basic and Advanced Individual Training (AIT) from the mid-1960s to the early 1970s. The M14 was the last American battle rifle issued in quantity to U.S. military personnel. In 1967, it was officially replaced by the M16 assault rifle, a lighter weapon with a smaller, intermediate cartridge. The M14 rifle remains in limited service across all branches of the U.S. military, with variants used as sniper and designated marksman rifles, accurized competition weapons, and ceremonial weapons by honor guards, color guards, drill teams and ceremonial guards.

Scope Mount
Scope mounts are used to attach telescopic sights or other types of sights to firearms. The scope sight itself is usually made for only one of two main types of mounts, which can be classified as ''scopes for ring mounts'' (for example a 30 mm tube) or ''scopes for rail mounts'' (like for example the Zeiss rail). Words such as ''mounts'' and ''bases'' are used somewhat loosely, and can refer to several different parts which are either used together or in place of each other as ways to mount optical sights to firearms. When it comes to the interface of the firearm itself, the Picatinny rail is one of the most widespread standard for new firearms as of 2020. While most scopes are made for being mounted either with a ''ring mount'' or a ''rail mount'', some sights have an integral mounting mechanism allowing them to be attached directly to the firearm, like for example an integrated Picatinny mount. In addition, there are many proprietary and brand-specific types of mounts that ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the World War II by country, vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies of World War II, Allies and the Axis powers. World War II was a total war that directly involved more than 100 million Military personnel, personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Air warfare of World War II, Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the Atomic bombings of Hiroshima and Nagasaki, only two nuclear weapons ever used in war. World War II was by far the List of wars by death toll, deadliest conflict in hu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Designated Marksman
A designated marksman (DM), squad advanced marksman (AD) or squad designated marksman (SDM) is a military marksman role in an infantry squad. The term ''sniper'' was used in Soviet doctrine although the soldiers using the Dragunov SVD were the first to use a specifically designed designated marksman rifle. The analogous role in the Israel Defense Forces is ''sharpshooter''. The DM's role is to supplement the attached squad by providing accurate fire upon enemy targets at distances up to . Due to the need for repeated effective fire, the DM is usually equipped with a scoped semi-automatic rifle called a designated marksman rifle (DMR). Like snipers, DMs are trained in scouting and precise shooting, but unlike the more specialized "true" sniper (who often operate independently), they operate as an intrinsic part of an infantry fireteam and are tasked to lay down accurate support fire at valuable targets as per tactical necessity, thus extending the reach of the fireteam.

Sniper Rifle
A sniper rifle is a high-precision, long-range rifle. Requirements include accuracy, reliability, mobility, concealment and optics for anti-personnel, anti-materiel and surveillance uses of the military sniper. The modern sniper rifle is a portable shoulder-fired weapon system with a choice between bolt-action or semi-automatic action, fitted with a telescopic sight for extreme accuracy and chambered for a high-ballistic performance centerfire cartridge. History The Whitworth rifle was arguably the first long-range sniper rifle in the world. Designed by Sir Joseph Whitworth, a prominent British engineer, it used barrels with hexagonal polygonal rifling, which meant that the projectile did not have to bite into the rifling grooves as was done with conventional rifling. His rifle was far more accurate than the Pattern 1853 Enfield, which had shown some weaknesses during the recent Crimean War. At trials in 1857, which tested the accuracy and range of both weapons, Whitworth's ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Optics
Optics is the branch of physics that studies the behaviour and properties of light, including its interactions with matter and the construction of instruments that use or detect it. Optics usually describes the behaviour of visible, ultraviolet, and infrared light. Because light is an electromagnetic wave, other forms of electromagnetic radiation such as X-rays, microwaves, and radio waves exhibit similar properties. Most optical phenomena can be accounted for by using the classical electromagnetic description of light. Complete electromagnetic descriptions of light are, however, often difficult to apply in practice. Practical optics is usually done using simplified models. The most common of these, geometric optics, treats light as a collection of rays that travel in straight lines and bend when they pass through or reflect from surfaces. Physical optics is a more comprehensive model of light, which includes wave effects such as diffraction and interference that ...

Zastava M70
The Zastava M70 ( sr-Cyrl, Застава М70) is a 7.62x39mm assault rifle. Developed in Yugoslavia by Zastava Arms during the 1960s, the M70 was an unlicensed derivative of the Soviet AK-47 (specifically the Type 3 variant). It became the standard issue infantry weapon in the Yugoslav People's Army in 1970, complementing and later superseding the Zastava M59/66. Both the original M70 design, as well as commercial variants of the weapon without select-fire capability, known as the Zastava PAP series, are still produced by Zastava for export. History Beginning in 1952, Yugoslavia's defense industry had been experimenting with new automatic rifle designs, mostly patterned after the German StG 44, an unknown quantity of which had been captured by Yugoslav Partisans during World War II. In 1959, two Albanian soldiers defected to Yugoslavia with Soviet AK-47s, which were promptly passed on by the Yugoslav government to be inspected by Zastava engineers. Zastava was able to make ...

Type 06 Rifle Grenade
The is a rifle grenade used by the JGSDF. It can be launched from the Howa Type 89 or Howa Type 64 rifles without other attachments. History The JGSDF did not adopt the US-made M203 grenade launcher for general use after a thorough examination. Development of the Type 06 rifle grenade began in 1998 by the JGSDF Ground Research and Development Command after evaluations were done in 2001 and in 2005. The Type 06 was finished and adopted by the JGSDF in 2006, being manufactured by Daikin Industries under its Defense Systems Division. The Type 06 had been fired first in exercises done by the JGSDF's 3rd Mechanized Infantry Regiment. It has been subsequently shown in various war game exercises. Description The grenade does not need a launching attachment, because it was designed for riflemen and not for grenadiers. However, a simplified aiming sight can be attached. It contains a HEAT warhead for defeating tank armor. It is also equipped with a built-in time fuse for safety upon fai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Muzzle Climb
Muzzle rise, muzzle flip or muzzle climb refers to the tendency of a firearm's or airgun's muzzle (front end of the barrel) to rise up after firing. It more specifically refers to the seemingly unpredictable "jump" of the firearm's muzzle, caused by combined recoil from multiple shots being fired in quick succession. It has an adverse effect on maintaining accuracy with using automatic weapons or rapid-firing semi-automatic firearms, as a moving muzzle can throw off the shooter's aim, causing subsequent shots to miss the intended target. Reason The primary reason for muzzle rise is that for nearly all guns, the bore axis (longitudinal centerline of the barrel) is above the gun's center of mass, while the contact points between the shooter and the gun (e.g. grips and stock) are often all below the center of mass. When the gun is fired, the bullet motion and the escaping propellant gases exert a reactional recoil directly backwards along the bore axis, while the countering forwa ...

Recoil
Recoil (often called knockback, kickback or simply kick) is the rearward thrust generated when a gun is being discharged. In technical terms, the recoil is a result of conservation of momentum, as according to Newton's third law the force required to accelerate something will evoke an equal but opposite reactional force, which means the forward momentum gained by the projectile and exhaust gases (ejectae) will be mathematically balanced out by an equal and opposite momentum exerted back upon the gun. In hand-held small arms, the recoil momentum will be eventually transferred to the ground, but will do so through the body of the shooter hence resulting in a noticeable impulse commonly referred to as a "kick". In heavier mounted guns, such as heavy machine guns or artillery pieces, recoil momentum is transferred to the Earth's surface through the platform on which the weapon is mounted. In order to bring the rearward moving gun to a halt, the momentum acquired by the gu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
