Howa Type 64
The , referred to as the , is a Japanese battle rifle used exclusively by the Japan Self-Defense Forces and the Japan Coast Guard, Japanese Coast Guard. It is a Gas-operated reloading, 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 Japanese arms-export ban, 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 It has been superseded by the more advanced Howa Type 89 from 1989 to 1990, but is still in service with all branches of the Self-Defense Forces and the Japanese Coast Guard.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 Assault Team, Special Armed Police unit. History Roughly a decade after the creation of the Japan Self-Defense Forces, Japanese Self Defense Forces, the Ministry of Defense (Japan), Defense Agency decided to make a domestically designed and manufactured main battle rifle to replace the aging M1 Garand rifles tha ...

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 ga ...

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 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. The growth of the DM rifle can be attributed to two main influences; the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sniper Rifle
A sniper rifle is a high-precision, long range shooting, long-range rifle. Requirements include high accuracy, reliability, mobility, concealment, and optics, for anti-personnel weapon, anti-personnel, anti-materiel rifle, anti-materiel and surveillance uses by military snipers. The modern sniper rifle is a portable shoulder-fired rifle with either a bolt action or semi-automatic firearm, semi-automatic action (firearms), action, fitted with a telescopic sight for extreme accuracy and chambered for a high-ballistic performance Centerfire ammunition, centerfire cartridge (firearms), cartridge. History The Whitworth rifle was arguably the first long-range sniper rifle in the world. Designed in 1854 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 with conventional rifling. His rifle was far more accurate than the Pattern 1853 Enfield, which ha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SVT-40
The SVT-40 () is a Soviet semi-automatic battle rifle that saw widespread service during and after World War II. It was intended to be the new service rifle of the Soviet Red Army, but its production was disrupted by the German invasion in 1941, resulting in a change back to the Mosin–Nagant rifle for the duration of World War II although both rifles served concurrently. History In the early 1930s, the Soviet Union requested the development of a semi-automatic rifle to replace the Mosin-Nagant, taking inspiration from the Mexican Mondragón rifle. The design was left up to two individuals, Sergei Simonov and Fedor Tokarev. Simonov, who had experience in developing the Fedorov Avtomat, created a prototype for the AVS-36 in 1931. The rifle was used during the Winter War but was removed from service in 1941 due to design flaws. SVT-38 In 1938, Tokarev's rifle was accepted for production, under the designation ''SVT-38'' with hopes that it would become the new stand ...

FN FAL
The FAL (, English: Light Automatic Rifle) is a battle rifle designed in Belgium by Dieudonné Saive and manufactured by FN Herstal and others since 1953. During the Cold War the FAL was adopted by many countries of the NATO, North Atlantic Treaty Organization (NATO), with the notable exception of the United States. It is one of the most widely used rifles in history, having been used by more than 90 countries. It received the title "the right arm of the free world" from its adoption by many countries that identified as part of free world. It is chambered in 7.62×51mm NATO, although originally designed for the Intermediate cartridge, intermediate .280 British. A license-built version of the FAL was produced and adopted by the United Kingdom and throughout the Commonwealth of Nations, Commonwealth as the L1A1 Self-Loading Rifle. History In 1946, the first FAL prototype was completed. It was designed to fire the intermediate 7.92×33mm Kurz cartridge developed and used by the ...

Zastava M70
The Zastava M70 ( sr-Cyrl, Застава М70) is a 7.62×39mm assault rifle developed in the Socialist Federal Republic of Yugoslavia by Zastava Arms. The M70 was an unlicensed derivative of the Soviet Union, Soviet AK-47 (specifically the Type 3 variant). Due to political differences between the Soviet Union and Yugoslavia at the time, namely the latter's refusal to join the Warsaw Pact, Zastava was unable to directly obtain the technical specifications for the AK and opted to Reverse engineering, reverse engineer the weapon type. Although the M70 was functionally identical to the AK, it had unique in-built features that better enabled it to fire rifle grenades. These included a thicker receiver, a new latch for the dust cover to ensure it would not be jarred loose by a grenade discharge, and a folding grenade sight bracket over the rifle's gas block, which also shut off the gas system when raised. The M70 became the standard issue infantry weapon in the Yugoslav People's Army ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 fail ... [...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, for 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. Basics Any launching system (weapon or not) generates recoil. However recoil only constitutes a problem in the field of artillery and firearms due to the magnitude of the forces at play. Gun chamber pressures and projectile acceleration forces are tremendous, on the order of tens to hundreds mega pascalAs a perspective, the atmospheric pressure is roughly 0.1 megapascal. and tens of thousands of times the acceleration of gravity ( g's), both necessary to launch the projectile a ...
