Spanish State
Francoist Spain ( es, España franquista), or the Francoist dictatorship (), was the period of Spanish history between 1939 and 1975, when Francisco Franco ruled Spain after the Spanish Civil War with the title . After his death in 1975, Spanish transition to democracy, Spain transitioned into a democracy. During this time period, Spain was officially known as the Spanish State (). The nature of the regime evolved and changed during its existence. Months after the start of the Spanish Civil War in July 1936, Franco emerged as the dominant rebel military leader and was proclaimed head of state on 1 October 1936, ruling a dictatorship over the territory controlled by the Nationalist faction (Spanish Civil War), Nationalist faction. The Unification Decree (Spain, 1937), 1937 Unification Decree, which merged all parties supporting the rebel side, led to Nationalist Spain becoming a single-party regime under the FET y de las JONS. The end of the war in 1939 brought the extension of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Battle Rifle
A battle rifle is a service rifle chambered to fire a fully powered cartridge. The term "battle rifle" is a retronym created largely out of a need to better differentiate the intermediate cartridge, intermediate-powered assault rifles (e.g. the StG-44, AK-47, M16 rifle, M16, Steyr AUG, AUG) from full-powered rifles (e.g. the FG-42, AVS-36, FN FAL, and M14 rifle, M14, as well as the H&K G3 outside of sniping uses) as both classes of modern firearms have a similar appearance and share many of the same features such as magazine (firearms), detachable magazines, pistol grips, separate upper and lower receiver (firearms), receivers etc. Battle rifles were most prominent from the 1940s to the 1970s, when they were used as Service rifle, service rifles. While modern battle rifles largely resemble modern assault rifle designs, which replaced battle rifles in most roles, the term may also describe older military full-powered semi-automatic rifles such as the M1 Garand, SVT-40, Gewehr 41, Ge ...

Gas-operated Reloading
Gas-operation is a system of operation used to provide energy to operate locked breech, autoloading firearms. In gas-operation, a portion of high-pressure gas from the cartridge being fired is used to power a mechanism to dispose of the spent case and insert a new cartridge into the chamber. Energy from the gas is harnessed through either a port in the barrel or a trap at the muzzle. This high-pressure gas impinges on a surface such as a piston head to provide motion for unlocking of the action, extraction of the spent case, ejection, cocking of the hammer or striker, chambering of a fresh cartridge, and locking of the action. History The first mention of using a gas piston in a single-shot breech-loading rifle comes from 1856, by the German Edward Lindner who patented his invention in the United States and Britain. In 1866, Englishman William Curtis filed the first patent on a gas-operated repeating rifle, but subsequently failed to develop that idea further. Between 18 ...

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] |
Krummlauf
The ''Krummlauf'' (English: "curved barrel") is a bent barrel attachment for the Sturmgewehr 44 (StG 44) rifle developed by Germany in World War II. The curved barrel included a periscope sighting device for shooting around corners from a safe position. Description It was produced in several variants: an "I" version for infantry use, a "P" version for use in tanks (to cover the dead areas in the close range around the tank and defend against assaulting infantry), versions with 30°, 45°, 60° and 90° bends, a version for the StG 44 and one for the MG 42. Only the 30° "I" version for the StG 44 was produced in many numbers. The bent barrel attachments had very short lifespans—approximately 300 rounds for the 30° version, and 160 rounds for the 45° variant—as the barrel and bullets fired were put under great stress. Another problem besides the short life-span was that the bending caused the bullets to shatter and exit the barrel in multiple fragments, producing an unint ...

StG-44
The StG 44 (abbreviation of Sturmgewehr 44, "assault rifle 44") is a German assault rifle developed during World War II by Hugo Schmeisser. It is also known by its early designations as the MP 43 and MP 44 (''Maschinenpistole 43'' and ''44''). The StG 44 was an improvement of an earlier design, the Maschinenkarabiner 42(H). The StG 44 was the first successful assault rifle, with features including an intermediate cartridge, controllable automatic fire, a more compact design than a battle rifle with a higher rate of fire, and being designed primarily for hitting targets within a few hundred metres. Other rifles at the time were designed to hit targets of over a thousand meters, but this was found to be in excess of the range in which most enemy engagements actually took place. The StG 44 fulfilled its role effectively, particularly on the Eastern Front, offering a greatly increased volume of fire compared to standard infantry rifles. The StG largely influenced the Soviet AK-4 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
CETME
CETME () is a Spanish government design and development establishment. While being involved in many projects CETME was mostly known for its small arms research and development. The CETME Model 58 and CETME Model L are its most notable projects. CETME also designed the CETME C2 9mm submachine gun, and the CETME Ameli light machine gun in 5.56×45mm NATO.

Intermediate Cartridge
An intermediate cartridge is a rifle/carbine cartridge that has significantly greater power than a pistol cartridge but still has a reduced muzzle energy compared to fully powered cartridges (such as the .303 British, 7.62×54mmR, 7.92×57mm Mauser, 7.7×58mm Arisaka, .30-06 Springfield, or 7.62×51mm NATO), and therefore is regarded as being "intermediate" between traditional rifle and handgun calibers. As their recoil is significantly reduced compared to full-power cartridges, fully automatic rifles firing intermediate cartridges are relatively easy to control. However, even though they are less powerful than a traditional full-power cartridge, the external ballistics are still sufficient for an effective range of , which covers most typical infantry engagement situations in modern warfare. This allowed for the development of the assault rifle, a type of versatile selective fire small arms that is lighter and more compact than traditional battle rifles that fire full-po ...

NATO
The North Atlantic Treaty Organization (NATO, ; french: Organisation du traité de l'Atlantique nord, ), also called the North Atlantic Alliance, is an intergovernmental military alliance between 30 member states – 28 European and two North American. Established in the aftermath of World War II, the organization implemented the North Atlantic Treaty, signed in Washington, D.C., on 4 April 1949. NATO is a collective security system: its independent member states agree to defend each other against attacks by third parties. During the Cold War, NATO operated as a check on the perceived threat posed by the Soviet Union. The alliance remained in place after the dissolution of the Soviet Union and has been involved in military operations in the Balkans, the Middle East, South Asia, and Africa. The organization's motto is ''animus in consulendo liber'' (Latin for "a mind unfettered in deliberation"). NATO's main headquarters are located in Brussels, Belgium, while NATO ...
