Personal Defense Weapon
Personal defense weapons (PDWs) are a class of compact, magazine-fed automatic firearms that are typically submachine guns designed to fire rifle-like cartridges. Most PDWs fire a small-caliber (generally less than in bullet diameter), high-velocity centerfire bottleneck cartridge resembling a scaled-down intermediate cartridge, essentially making them an "in-between" hybrid between a submachine gun and a conventional carbine assault rifle. The use of these rifle-like cartridges gives the PDWs much better ballistic performance ( effective range, external ballistics and armor-penetrating capability) than conventional submachine guns, which fire larger-caliber but slower and less aerodynamic handgun cartridges. The low recoil of these "sub-intermediate" cartridges also makes muzzle jumps on PDWs (which typically have short barrels) much easier to handle than short-barreled rifles, especially when shooting in automatic fire or burst fire. The name describes the weapon's ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
FN P90 PDW
The FN P90 is a personal defense weapon chambered for the FN 5.7×28mm, 5.7×28mm Cartridge (firearms), cartridge, also classified as a submachine gun, designed and manufactured by FN Herstal in Belgium. Created in response to NATO requests for a replacement for 9×19mm Parabellum firearms, the P90 was designed as a compact but powerful firearm for vehicle crews, operators of crew-served weapons, support personnel, special forces, and counter-terrorist groups. Designed in conjunction with the FN Five-seven pistol and FN 5.7×28mm, FN 5.7×28mm NATO ammunition, development of the weapon began in 1986, and production commenced in 1990, when it was known as the ''Project 9.0'' (from which the "90" in its name is derived), whereupon the 5.7×28mm ammunition was redesigned and shortened. A modified version of the P90 with a Magazine (firearms), magazine adapted to use the new ammunition was introduced in 1993, and the Five-seven pistol was subsequently introduced as a companion weapo ...

Short-barreled Rifle
Short-barreled rifle broadly refers to any rifle with an unusually short Gun barrel, barrel. The term carbine describes a production rifle with a reduced barrel length for easier handling in confined spaces. Concern about concealed carry, concealment for illegal purposes has encouraged regulations specifying minimum barrel lengths and overall lengths. Measurement method Barrel length is measured from the end of the Muzzle (firearms), muzzle to the front of the breechface, typically by inserting a measuring rod into the barrel. Barrel length may partially comprise a permanently attached muzzle accessory (such as a muzzle brake, recoil compensator or flash suppressor). Overall length is measured between the extreme ends of the gun, along a centerline which passes through the middle of the barrel. For rifles fitted with folding or telescoping Stock (firearms), stocks (such as M1 carbine#Carbine.2C Cal .30.2C M1A1, U.S. Carbine M1A1), US Federal guidelines state that measurement is pe ...

CRISAT
Collaborative Research Into Small Arms Technology (CRISAT) is the name of a series of studies conducted by the North Atlantic Treaty Organisation (NATO), identifying and defining threats with regard to the standardisation in the manufacturing of military equipment. The CRISAT target is defined as a 1.6 mm titanium (UK IMI Ti 318) plate supplemented by 20 layers of Kevlar (UK/SC/4468) as defined in STANAG 4512.NATO. (2004). STANAG 4512 The CRISAT target will stop the commonly used 9×19mm Parabellum full metal jacket cartridge, but it is pierced by the newer 5.7×28mm and 4.6×30mm personal defense weapon Personal defense weapons (PDWs) are a class of compact, magazine-fed automatic firearms that are typically submachine guns designed to fire rifle-like cartridges.

Service Rifle
A service rifle (or standard-issue rifle) is a rifle a military issues to its regular infantry. In modern militaries, this is generally a versatile, rugged, and reliable assault rifle or battle rifle, suitable for use in nearly all environments and is effective in most combat situations. Almost all modern militaries are issued service pistols as sidearms to accompany their service rifles. The term can also be used to describe weapons issued by non-military forces, such as law enforcement or paramilitaries. If the issued weapon is not a rifle or carbine, but instead a different type of firearm intended to serve in a specialized role such as a combat shotgun, submachine gun, or light machine gun, it is called a service firearm or service weapon. History Firearms with rifled barrels existed long before the 19th century, but were not widely used until the mid-19th century in conflicts such as the Crimean War and American Civil War. Thus, rifles in the early 19th century were ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Suppressive Fire
In military science, suppressive fire is "fire that degrades the performance of an enemy force below the level needed to fulfill its mission". When used to protect exposed friendly troops advancing on the battlefield, it is commonly called covering fire. Suppression is usually only effective for the duration of the fire. It is one of three types of fire support, which is defined by NATO as "the application of fire, coordinated with the maneuver of forces, to destroy, neutralise or suppress the enemy". Before NATO defined the term, the British and Commonwealth armies generally used "neutralisation" with the same definition as suppression. NATO now defines neutralisation as "fire delivered to render a target temporarily ineffective or unusable". Usage Suppressive fire usually achieves its effect by threatening casualties to individuals who expose themselves to it, forcing them to inactivity and ineffectiveness by keeping their heads down, 'or else take a bullet'.

Close-quarters Combat
Close-quarters battle (CQB), also called close-quarters combat (CQC), is a close combat situation between multiple combatants involving ranged (typically firearm-based) or melee combat. It can occur between military units, law enforcement and Crime, criminal elements, and in other similar situations. CQB is typically defined as a short duration, high intensity conflict characterized by sudden violence at close range. History Close-quarters battle has occurred since the beginning of warfare, in the form of melee combat, the use of ranged weaponry (such as Sling (weapon), slings, Bow and arrow, bows, and muskets) at close range, and the necessity of bayonets. During World War I, CQB was a significant part of trench warfare, where enemy soldiers would fight in close and narrow quarters in attempts to capture trenches. The origins of modern close-quarters battle lie in the combat methods pioneered by Assistant Commissioner William E. Fairbairn of the Shanghai Municipal Police, the p ...

Infiltration Tactics
In warfare, infiltration tactics involve small independent light infantry forces advancing into enemy rear areas, bypassing enemy frontline strongpoints, possibly isolating them for attack by follow-up troops with heavier weapons. Soldiers take the initiative to identify enemy weak points and choose their own routes, targets, moments and methods of attack; this requires a high degree of skill and training, and can be supplemented by special equipment and weaponry to give them more local combat options. Forms of these infantry tactics were used by skirmishers and irregulars dating back to classical antiquity, but only as a defensive or secondary tactic; decisive battlefield victories were achieved by shock combat tactics with heavy infantry or heavy cavalry, typically charging '' en masse'' against the primary force of the opponent. By the time of early modern warfare, defensive firepower made this tactic increasingly costly. When trench warfare developed to its heigh ...

Skirmisher
Skirmishers are light infantry or light cavalry soldiers deployed as a vanguard, flank guard or rearguard to screen a tactical position or a larger body of friendly troops from enemy advances. They may be deployed in a skirmish line, an irregular open formation that is much more spread out in depth and in breadth than a traditional line formation. Their purpose is to harass the enemy by engaging them in only light or sporadic combat to delay their movement, disrupt their attack, or weaken their morale. Such tactics are collectively called skirmishing. An engagement with only light, relatively indecisive combat is sometimes called a skirmish even if heavier troops are sometimes involved. Skirmishers can be either regular army units that are temporarily detached to perform skirmishing or specialty units that were specifically armed and trained for such low-level irregular warfare tactics. Light infantry, light cavalry (historically), and irregular units often specialize in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Signaller
A signaller, signalman, colloquially referred to as a radioman or signaleer in the armed forces is a specialist soldier, sailor or airman responsible for military communications. Signallers, a.k.a. Combat Signallers or signalmen or women, are commonly employed as radio or telephone operators, relaying messages for field commanders at the front line (Army units, Ships or Aircraft), through a Command hierarchy, chain of command which includes field headquarters. Messages are transmitted and received via a communications infrastructure comprising fixed and mobile installations. Duties In the past, signalling skills have included the use of: Heliograph, Aldis lamp, Flag semaphore, semaphore flags, "Don R" (Dispatch Riders) and even Homing pigeon, carrier pigeons. Modern signallers are responsible for the battlefield voice and data communication and information technology infrastructure or in common English terms, they may carry a backpack radio transceiver used to communicate to ...

Artillery
Artillery consists of ranged weapons that launch Ammunition, munitions far beyond the range and power of infantry firearms. Early artillery development focused on the ability to breach defensive walls and fortifications during sieges, and led to heavy, fairly immobile siege engines. As technology improved, lighter, more mobile field artillery cannons were developed for battlefield use. This development continues today; modern self-propelled artillery vehicles are highly mobile weapons of great versatility generally providing the largest share of an army's total firepower. Originally, the word "artillery" referred to any group of soldiers primarily armed with some form of manufactured weapon or armour. Since the introduction of gunpowder and cannon, "artillery" has largely meant cannon, and in contemporary usage, usually refers to Shell (projectile), shell-firing Field gun, guns, howitzers, and Mortar (weapon), mortars (collectively called ''barrel artillery'', ''cannon artil ...

Military Logistics
Military logistics is the discipline of planning and carrying out the movement, supply, and maintenance of military forces. In its most comprehensive sense, it is those aspects or military operations that deal with: * Design, development, Military acquisition, acquisition, storage, distribution, maintenance, evacuation, and disposition of materiel. * Transport of personnel. * Acquisition or construction, maintenance, operation and disposition of facilities. * Acquisition or furnishing of services. * Medical and health service support. Etymology and definition The word "logistics" is derived from the Greek adjective meaning "skilled in calculating", and its corresponding Latin word . In turn this comes from the Greek , which refers to the principles of thought and action. Another Latin root, ''log-'', gave rise around 1380 to , meaning to lodge or dwell, and became the French verb , meaning "to lodge". Around 1670, the French King Louis XIV created the position of , an office ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
