RK 62
The RK 62 (from Finnish , 'assault rifle 62'), officially 7.62 RK 62 and commercially M62, is an assault rifle manufactured by Valmet and Sako. It is the standard issue infantry weapon of the Finnish Defence Forces. The RK 62 was designed in 1957–1962 by a Valmet engineer Lauri Oksanen and is based on the Polish licensed version of the Soviet AK-47 design. The RK 62 uses the same 7.62×39mm cartridge as the AK-47. Between 1965 and 1994 350,000 M62 rifles were produced jointly by Valmet and Sako. It is the basis of the IMI Galil, an Israeli-made assault rifle with many similarities. The RK 62 has a three-pronged flash suppressor, and a groove for a specially designed knife bayonet, which can be used alone as a combat knife. The RK 95 TP is a more modern, improved version of the RK 62. One of the most distinctive features of the Valmet rifles, including the M62 and all subsequent variations, is the open-ended, three prong flash suppressor with a bayonet lug on its lower sid ...

Assault Rifle
An assault rifle is a select fire rifle that uses an intermediate cartridge, intermediate-rifle cartridge and a Magazine (firearms), detachable magazine.C. Taylor, ''The Fighting Rifle: A Complete Study of the Rifle in Combat'', F.A. Moyer ''Special Forces Foreign Weapons Handbook'', R.J. Scroggie, F.A. Moyer ''Special Forces Combat Firing Techniques'', Musgave, Daniel D., and Thomas B. Nelson, ''The World's Assault Rifles'', vol. II, The Goetz Company, Washington, D.C. (1967): 1 Assault rifles were first put into mass production and accepted into widespread service during World War II. The first assault rifle to see major usage was the German StG 44, a development of the earlier Maschinenkarabiner 42(H), Mkb 42.''Firearms: The Life Story of a Technology'', by Roger Pauly.

Tritium
Tritium () or hydrogen-3 (symbol T or H) is a rare and radioactive isotope of hydrogen with a half-life of ~12.33 years. The tritium nucleus (t, sometimes called a ''triton'') contains one proton and two neutrons, whereas the nucleus of the common isotope hydrogen-1 (''protium'') contains one proton and no neutrons, and that of non-radioactive hydrogen-2 ('' deuterium'') contains one proton and one neutron. Tritium is the heaviest particle-bound isotope of hydrogen. It is one of the few nuclides with a distinct name. The use of the name hydrogen-3, though more systematic, is much less common. Naturally occurring tritium is extremely rare on Earth. The atmosphere has only trace amounts, formed by the interaction of its gases with cosmic rays. It can be produced artificially by irradiation of lithium or lithium-bearing ceramic pebbles in a nuclear reactor and is a low-abundance byproduct in normal operations of nuclear reactors. Tritium is used as the energy source in radio ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Northern Europe
The northern region of Europe has several definitions. A restrictive definition may describe northern Europe as being roughly north of the southern coast of the Baltic Sea, which is about 54th parallel north, 54°N, or may be based on other geographical factors such as climate and ecology. Climate The climate is mainly Oceanic climate (Cfb), Humid continental climate (Dfb), Subarctic climate (Dfc and Dsc) and Tundra (ET). Geography Northern Europe might be defined roughly to include some or all of the following areas: British Isles, Fennoscandia, the peninsula of Jutland, the Baltic region, Baltic plain that lies to the east, and the many islands that lie offshore from mainland northern Europe and the main European continent. In some cases, Greenland is also included, although it is only politically European, comprising part of the Kingdom of Denmark, and not considered to be geographically in Europe. The area is partly mountainous, including the northern volcanic islands ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Minute Of Arc
A minute of arc, arcminute (abbreviated as arcmin), arc minute, or minute arc, denoted by the symbol , is a unit of angular measurement equal to of a degree. Since one degree is of a turn, or complete rotation, one arcminute is of a turn. The nautical mile (nmi) was originally defined as the arc length of a minute of latitude on a spherical Earth, so the actual Earth's circumference is very near . A minute of arc is of a radian. A second of arc, arcsecond (abbreviated as arcsec), or arc second, denoted by the symbol , is a unit of angular measurement equal to of a minute of arc, of a degree, of a turn, and (about ) of a radian. These units originated in Babylonian astronomy as sexagesimal (base 60) subdivisions of the degree; they are used in fields that involve very small angles, such as astronomy, optometry, ophthalmology, optics, navigation, land surveying, and marksmanship. To express even smaller angles, standard SI prefixes can be employed; the milliar ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Birch
A birch is a thin-leaved deciduous hardwood tree of the genus ''Betula'' (), in the family Betulaceae, which also includes alders, hazels, and hornbeams. It is closely related to the beech- oak family Fagaceae. The genus ''Betula'' contains 30 to 60 known taxa of which 11 are on the IUCN 2011 Red List of Threatened Species. They are typically short-lived pioneer species and are widespread in the Northern Hemisphere, particularly in northern areas of temperate climates and in boreal climates. Birch wood is used for a wide range of purposes. Description Birch species are generally small to medium-sized trees or shrubs, mostly of northern temperate and boreal climates. The simple leaves are alternate, singly or doubly serrate, feather-veined, petiolate and stipulate. They often appear in pairs, but these pairs are really borne on spur-like, two-leaved, lateral branchlets. The fruit is a small samara, although the wings may be obscure in some species. They differ from t ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Pistol
A pistol is a type of handgun, characterised by a gun barrel, barrel with an integral chamber (firearms), chamber. The word "pistol" derives from the Middle French ''pistolet'' (), meaning a small gun or knife, and first appeared in the English language when early handguns were produced in Europe. In colloquial usage, the word "pistol" is often used as a generic term to describe ''any'' type of handgun, inclusive of revolvers (which have a single barrel and a separate cylinder (firearms), cylinder housing multiple chambers) and the pocket gun, pocket-sized derringers (which are often multiple-barrel firearm, multi-barrelled). The most common type of pistol used in the contemporary era is the semi-automatic pistol. The older single-shot and lever-action pistols are now rarely seen and used primarily for nostalgic hunting and historical reenactment. Fully-automatic machine pistols are uncommon in civilian usage because of their generally poor recoil-controllability (due to the l ...

Combat Knife
A combat knife is a fighting knife designed for military use and primarily intended for hand-to-hand combat, hand-to-hand or close combat fighting.Peterson, Harold L., ''Daggers and Fighting Knives of the Western World'', Courier Dover Publications, , (2001), p. 80: "Right at the outset trench knives were introduced by both sides during World War I, so that the common soldier was once again equipped with a knife designed primarily for combat."''Catalog of Standard Ordnance Items'', Washington, D.C.: U.S. Army Ordnance Publications (1943) Since the end of trench warfare, most military combat knives have been secondarily designed for utility use (clearing foliage, chopping branches for cover, opening ammunition crates, etc.) in addition to their original role as close-quarter combat weapons, and may be referred to as "fighting-utility knives." On the other hand, military knives that are intended primarily for use in a role other than combat are typically referred to by their prima ...

Knife Bayonet
A knife bayonet is a knife which can be used both as a bayonet, combat knife, or utility knife as a cutting and thrusting tool or weapon. The knife bayonet became the almost universal form of bayonet in the 20th century due to its versatility and effectiveness. Spike bayonets proved useless when separated from the rifle and ineffective in trench warfare; and while versatile, sword bayonets proved to be impractical weapons in trench warfare because of their overall length. The first knife bayonet to see widespread service was the 10 inch (25.4 cm) blade Seitengewehr 1871/84, which became the standard German infantry bayonet in 1884. Its derivative, the Seitengewehr 1884/98, would go on in use until 1945 in German service. The knife bayonets are basically fighting knives or utility knives with a lug and/or muzzle ring to attach to the barrel of a firearm such as an assault rifle, submachine gun A submachine gun (SMG) is a magazine (firearms), magazine-fed automatic firearm, aut ...

Flash Suppressor
A flash suppressor, also known as a flash guard, flash eliminator, flash hider, or flash cone, is a device attached to the muzzle (firearms), muzzle of a rifle that reduces its Muzzle flash, visible signature while firing by cooling or dispersing the burning gases that exit the muzzle, a phenomenon typical of carbine-length weapons. Its primary intent is to reduce the chances that the shooter will be blinded in low-light shooting conditions. Contrary to popular belief, it is only a minor secondary benefit if a flash suppressor reduces the intensity of the flash visible to the enemy. A flash suppressor is different from a muzzle brake, although they are typically mounted in the same position and sometimes confused with each other. While the former is intended to reduce visible flash, a muzzle brake is designed to reduce recoil inherent to large cartridges and typically does not reduce visible flash. Rationale Pre-20th century rifle designs tended to have longer barrels than moder ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

IMI Galil
The IMI Galil () is a family of Israeli-made automatic rifles chambered for the 5.56×45mm NATO and 7.62×51mm NATO cartridges. Originally designed by Yisrael Galili (inventor), Yisrael Galili and Yakov Lior in the late 1960s, the Galil was first produced by the state-owned IMI Systems, Israel Military Industries and is now exported by the privatized Israel Weapon Industries. The first Galil rifle was manufactured using RK 62 Receiver (firearms), receivers.Knupp, Jeremiah (December 28, 2017"Galil ACE: IWI Brings the AK Into the Modern Era" ''American Rifleman''. Moreover, the Galil design is largely based on the Finland, Finnish rifle RK 62 (a derivative of the AK-47). The Israeli Ground Forces, Israeli Army initially deployed the 5.56×45mm NATO Galil in three basic configurations; the automatic rifle machine-gun (ARM), the automatic rifle (AR), and the short automatic rifle (SAR). A modernised, redesigned version of the Galil is produced since 2008, known as the IWI ACE, Gali ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
