SG-43 Goryunov
The SG-43 Goryunov (Russian: Станковый пулемёт системы Горюнова, ''Stankovyy pulyemyot sistyemy Goryunova'', meaning "Mounted machinegun, Goryunov design") was a Soviet medium machine gun that was introduced during the Second World War. It was chambered for the 7.62×54mmR cartridge, and was introduced in 1943 as a replacement for the older M1910 Maxim machine guns. It was mounted on wheeled mounts, tripods and armored vehicles. Design The SG-43 used a tilting breechblock, moving sideways and locking into the side of the receiver. The feed is not straightforward, as the gun fires the 7.62×54mmR round, and this has to be withdrawn rearwards from the belt before ramming into the breech. The reciprocating motion is achieved by using two claws to pull the round from the belt, and then an arm pushes the round into the cartridge guide ready for the bolt to carry it to the breech. Despite this complication, the SG-43 was remarkably reliable and feed jams ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Soviet Union
The Soviet Union,. officially the Union of Soviet Socialist Republics. (USSR),. was a transcontinental country that spanned much of Eurasia from 1922 to 1991. A flagship communist state, it was nominally a federal union of fifteen national republics; in practice, both its government and its economy were highly centralized until its final years. It was a one-party state governed by the Communist Party of the Soviet Union, with the city of Moscow serving as its capital as well as that of its largest and most populous republic: the Russian SFSR. Other major cities included Leningrad (Russian SFSR), Kiev (Ukrainian SSR), Minsk ( Byelorussian SSR), Tashkent (Uzbek SSR), Alma-Ata (Kazakh SSR), and Novosibirsk (Russian SFSR). It was the largest country in the world, covering over and spanning eleven time zones. The country's roots lay in the October Revolution of 1917, when the Bolsheviks, under the leadership of Vladimir Lenin, overthrew the Russian Provisional Government ...

Armoured Personnel Carrier
An armoured personnel carrier (APC) is a broad type of armoured military vehicle designed to transport personnel and equipment in combat zones. Since World War I, APCs have become a very common piece of military equipment around the world. According to the definition in the Treaty on Conventional Armed Forces in Europe, an APC is "an armoured combat vehicle which is designed and equipped to transport a combat infantry squad and which, as a rule, is armed with an integral or organic weapon of less than 20 millimetres calibre." Compared to infantry fighting vehicles (IFVs), which are also used to carry infantry into battle, APCs have less armament and are not designed to provide direct fire support in battle. Infantry units which travel in APCs are known as mechanized infantry. Some militaries also make a distinction between infantry units which use APCs and infantry units which use IFVs, with the latter being known as armoured infantry in such militaries.

Cocking Handle
The cocking handle, also known as charging handle or bolt handle, is a device on a firearm which, when manipulated, results in the bolt being pulled to the rear, putting the hammer/ striker into a spring-loaded ("cocked") "ready and set" position, allowing the operator to open the breech and eject any spent/unwanted cartridge/shell from the chamber, and then load a new round from the magazine or belt if required. By opening the breech, it also helps the operator to verify that the weapon's chamber is clear of any rounds or other obstructions; to clear a stoppage such as a jam, double-feed, stovepipe or misfire; to facilitate moving the bolt back into battery, acting as a forward assist (but not necessarily); and to release a bolt locked to the rear by a catching mechanism on a firearm equipped with a "last round bolt hold open" (LRBHO) feature. These devices vary significantly between firearms but may occur in the form of a small protrusion or hook from the side of the bolt, a ...

Reciprocating Motion
Reciprocating motion, also called reciprocation, is a repetitive up-and-down or back-and-forth linear motion. It is found in a wide range of mechanisms, including reciprocating engines and pumps. The two opposite motions that comprise a single reciprocation cycle are called strokes. A crank can be used to convert into reciprocating motion, or conversely turn reciprocating motion into circular motion. For example, inside an internal combustion engine (a type of reciprocating engine), the expansion of burning fuel in the cylinders periodically pushes the piston down, which, through the connecting rod, turns the crankshaft. The continuing rotation of the crankshaft drives the piston back up, ready for the next cycle. The piston moves in a reciprocating motion, which is converted into circular motion of the crankshaft, which ultimately propels the vehicle or does other useful work. The reciprocating motion of a pump piston is close to, but different from, sinusoidal simple harmon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Breech-loading Weapon
A breechloader is a firearm in which the user loads the ammunition (cartridge or shell) via the rear (breech) end of its barrel, as opposed to a muzzleloader, which loads ammunition via the front ( muzzle). Modern firearms are generally breech-loading – except for replicas of vintage weapons. Early firearms before the mid-19th century were almost entirely muzzle-loading. Mortars and the Russian GP-25 grenade launcher are the only muzzleloaders remaining in frequent modern usage. However, referring to a weapon specifically as breech loading is mostly limited to single-shot or otherwise non-repeating firearms, such as double-barreled shotguns. Breech-loading provides the advantage of reduced reloading time, because it is far quicker to load the projectile and propellant into the chamber of a gun/cannon than to reach all the way over to the front end to load ammunition and then push them back down a long tube – especially when the projectile fits tightly and the ...

Single-shot
Single-shot firearms are firearms that hold only a single round of ammunition, and must be reloaded manually after every shot. The history of firearms began with single-shot designs, then multi-barreled designs appeared, and eventually many centuries passed before multi-shot repeater designs became commonplace. Compared to repeating firearms, single-shot designs have no moving parts (other than the trigger and hammer/firing pin or frizzen) and thus do not need a sizable receiver behind the barrel, and are much less complex than revolvers or magazine/belt-fed firearms. Although largely disappeared from military usage due to the slow rates of fire, single-shot designs are still produced by many manufacturers in both cartridge- and non-cartridge varieties, from zip guns to the highest-quality hunting and match guns. History Pre-cartridge era The vast majority of firearms before the introduction of metallic cartridges from the 1860s onwards, were single-shot muzzleloaders ...

Tripod
A tripod is a portable three-legged frame or stand, used as a platform for supporting the weight and maintaining the stability of some other object. The three-legged (triangular stance) design provides good stability against gravitational loads as well as horizontal shear forces, and better leverage for resisting tipping over due to lateral forces can be achieved by spreading the legs away from the vertical centre. Variations with one, two, and four legs are termed ''monopod'', ''bipod'', and ''quadripod'' (similar to a table). Etymology First attested in English in the early 17th century, the word ''tripod'' comes via Latin ''tripodis'' (GEN of ''tripus''), which is the romanization of Greek (''tripous''), "three-footed" (GEN , ''tripodos''), ultimately from (''tri-''), "three times" (from , ''tria'', "three") + (''pous''), "foot". The earliest attested form of the word is the Mycenaean Greek , ''ti-ri-po'', written in Linear B syllabic script. Cultural use Many cultur ...

PM M1910
The Pulemyot Maxima PM1910 (PM M1910) (Russian: Пулемёт Максима образца 1910 года, ''Pulemyot Maxima obraztsa 1910 goda'' – "Maxim's machine gun Model 1910") is a Heavy machine gun that was used by the Imperial Russian Army during World War I and the Red Army during the Russian Civil War and World War II. Later the gun saw service in the Korean War, the Vietnam War and the 2022 Russian invasion of Ukraine. History It was adopted in August 1910 and was derived from Hiram Maxim's Maxim gun, chambered for the standard Russian 7.62×54mmR rifle cartridge. The M1910 was mounted on a wheeled mount with a gun shield. In 1918–1920, the industry of Soviet Russia produced 21 thousand new Maxim 1910 machine guns for the Red Army.Пулемёты // Гражданская война и военная интервенция в СССР.

Medium Machine Gun
A medium machine gun (MMG), in modern terms, usually refers to a belt-fed machine gun firing a full-powered rifle cartridge, and is considered "medium" in weight (). Medium machine guns are light enough to be infantry-portable (as opposed to a heavy machine gun, which completely relies on mounting onto a weapons platform for operational stability and mobility), but still cumbersome enough to require a crew for optimal operational efficiency (as opposed to a light machine gun, which can be operated to full capacity by only a single gunner). History Late 19th century In the late 19th century, Gatling guns and other externally powered types, such as the Nordenfelt, were often made in different ranges of calibers, such as half-inch and one-inch. Thanks to their many barrels, overheating was not a major issue, and they were also quite heavy, being, essentially, heavy machine guns. When Hiram Maxim developed his recoil-powered machine gun that used a single barrel, the first ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Russian Language
Russian (russian: русский язык, russkij jazyk, link=no, ) is an East Slavic languages, East Slavic language mainly spoken in Russia. It is the First language, native language of the Russians, and belongs to the Indo-European languages, Indo-European language family. It is one of four living East Slavic languages, and is also a part of the larger Balto-Slavic languages.

Iron Sight
Iron sights are a system of physical alignment markers (usually made of metallic material) used as a sighting device to assist the accurate aiming of ranged weapons (such as a firearm, airgun, crossbow or even compound bow), or less commonly as a primitive finder sight for optical telescopes. The earliest sighting device, it relies completely on the viewer's naked eye (mostly under ambient lighting), and is distinctly different to optical sights such as telescopic sights, reflector (reflex) sights, holographic sights and laser sights, which make use of optical manipulation and/or active illumination, as well as the newer optoelectronics, which use digital imaging and even incorporate augmented reality. Iron sights are typically composed of two components mounted perpendicularly above the weapon's bore axis: a rear sight nearer (or ''proximally'') to the shooter's eye, and a front sight farther forward (or ''distally'') near the muzzle. During aiming, the shooter aligns his/ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
