MK47 Striker Closeup
The CMMG Mk47 Mutant is an American-made semi-automatic rifle chambered in 7.62×39mm caliber, made by CMMG Inc. It can accept all types of Kalashnikov pattern magazines, including steel, polymer and drum magazines. History The Mk47 was publicly announced for a release in 2014. In 2015, CMMG released its first production Mk47s to stores throughout the US. According to CMMG Production Manager Tyson Bradshaw, he mentioned that CMMG made the rifle due to the need of "consumers to have a reliable, U.S.-made rifle that could properly handle the dimensions of the 7.62x39 mm cartridge. To do this properly, it required CMMG to build the rifle around the caliber. Using AK magazines was an easy decision to make, because they are known to be some of the most reliable magazines available that work properly with the tapered cartridge". In SHOT Show 2015, CMMG representatives have suggested the possibility that they can do a variant of the rifle based on the 5.45×39mm caliber. Design T ...

Mk 19 Grenade Launcher
The Mk 19 grenade launcher (pronounced Mark 19) is an American 40 mm belt-fed automatic grenade launcher that was first developed during the Vietnam War. Overview The Mk 19 is a belt-fed, blowback-operated, air-cooled, crew-served, fully-automatic weapon that is designed not to cook off. It fires 40 mm grenades at a cyclic rate of 325 to 375 rounds per minute, giving a practical rate of fire of 60 rounds per minute (rapid) and 40 rounds per minute (sustained). The weapon operates on the blowback principle, which uses the chamber pressure from each fired round to load and re-cock the weapon. The Mk 19 can launch its grenade at a maximum distance of , though its effective range to a point target is about , since the large rear leaf sight is only graduated as far. The nearest safe distance to launch the grenade is 310 meters in training and 75 meters in combat. Though the Mk 19 has a flash suppressor, it serves only to save the eyesight of its ope ...

Grenade Launchers Of The United States
A grenade is an explosive weapon typically thrown by hand (also called hand grenade), but can also refer to a shell (explosive projectile) shot from the muzzle of a rifle (as a rifle grenade) or a grenade launcher. A modern hand grenade generally consists of an explosive charge ("filler"), a detonator mechanism, an internal striker to trigger the detonator, and a safety lever secured by a cotter pin. The user removes the safety pin before throwing, and once the grenade leaves the hand the safety lever gets released, allowing the striker to trigger a primer that ignites a fuze (sometimes called the delay element), which burns down to the detonator and explodes the main charge. Grenades work by dispersing fragments (fragmentation grenades), shockwaves (high-explosive, anti-tank and stun grenades), chemical aerosols (smoke and gas grenades) or fire ( incendiary grenades). Fragmentation grenades ("frags") are probably the most common in modern armies, and when the word ' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
40×53mm Grenade Launchers
4 (four) is a number, numeral and digit. It is the natural number following 3 and preceding 5. It is the smallest semiprime and composite number, and is considered unlucky in many East Asian cultures. In mathematics Four is the smallest composite number, its proper divisors being and . Four is the sum and product of two with itself: 2 + 2 = 4 = 2 x 2, the only number b such that a + a = b = a x a, which also makes four the smallest squared prime number p^. In Knuth's up-arrow notation, , and so forth, for any number of up arrows. By consequence, four is the only square one more than a prime number, specifically three. The sum of the first four prime numbers two + three + five + seven is the only sum of four consecutive prime numbers that yields an odd prime number, seventeen, which is the fourth super-prime. Four lies between the first proper pair of twin primes, three and five, which are the first two Fermat primes, like seventeen, which is the third. On the other ha ...

Ground Mobility Vehicle – (US)SOCOM Program
The Ground Mobility Vehicle (GMV) is a U.S. Special Operations Command, (US)SOCOM program, initially modifying Humvees into several variants for use by the United States special operations forces (SOF). Its design is mostly based on lessons learned during Operation Desert Storm, after an initial program, post 1985, for specialized HMMWVs for desert strike operations: the Desert Mobility Vehicle (DMV), or "Dumvee". GMV crews like to call them "gun trunks". The GMV program is superseded by the GMV 1.1, based on the General Dynamics Flyer 72. It is understood that under a seven-year indefinite delivery / indefinite-quantity (ID/IQ) contract (August 2013–August 2020), SOCOM wishes to procure 1,297 GMV 1.1s — to replace its 1,072 first generation, Humvee-based GMV units. History The GMV was based on special forces Humvees that were developed based on American military deployed to the Middle East. The program was initially meant to provide equipment related to mountainous de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Comparison Of Automatic Grenade Launchers
An automatic grenade launcher (AGL) or grenade machine gun is a grenade launcher that is capable of fully automatic fire, and is typically loaded with either an ammunition belt or magazine. These weapons are often mounted on vehicles or helicopters, as when these weapons are moved by infantry the weapon, its tripod, and ammunition, are a heavy load, requiring a small team. Other types of grenade launchers are typically much lighter and can easily be carried by just a single soldier. The Mark 19 Automatic Grenade Launcher, first fielded by the United States in 1966, and still widely used today, weighs 62.5 kg (137.58 lb) when attached to its tripod, and loaded with a box of ammunition. For comparison, the single-shot M79 grenade launcher weighs 2.93 kg (6.45 lb). Regardless of their weight, AGLs are still highly effective, and the Mark 19 is capable of indirect fire up to 2,200 metres, a role traditionally reserved for mortars. Even though the round carries less explosive than a 60 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
United States Special Operations Command
The United States Special Operations Command (USSOCOM or SOCOM) is the unified combatant command charged with overseeing the various special operations component commands of the Army, Marine Corps, Navy, and Air Force of the United States Armed Forces. The command is part of the Department of Defense and is the only unified combatant command created by an Act of Congress. USSOCOM is headquartered at MacDill Air Force Base in Tampa, Florida. The idea of an American unified special operations command had its origins in the aftermath of Operation Eagle Claw, the disastrous attempted rescue of hostages at the American embassy in Iran in 1980. The ensuing investigation, chaired by Admiral James L. Holloway III, the retired Chief of Naval Operations, cited lack of command and control and inter-service coordination as significant factors in the failure of the mission. Since its activation on 16 April 1987, U.S. Special Operations Command has participated in many operations, from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Indefinite Delivery-indefinite Quantity
In U.S. Federal government contracting, IDIQ is an abbreviation of the term indefinite delivery/indefinite quantity. This is a type of contract that provides for an indefinite quantity of supplies or services during a fixed period of time. The legal origin of IDIQ contracts is the Federal Acquisition Regulation (FAR) section 16.504(a) (). IDIQs are also sometimes called "Task Orders" or "Delivery Order Contracts." IDIQ contracts are a subtype of Indefinite Delivery Contract (IDC), which is a "vehicle that has been awarded to one or more vendors to facilitate the delivery of supply and service orders." Usage IDIQ contracts are most often used for on-call service contracts, Architect-Engineering (A-E) services, and job order contracting. Awards are usually for a specified number of base years with renewal options for additional years. These contracts typically do not exceed a total of five years in duration. The government places delivery orders (for supplies) or task orders (for ser ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
MK285
The MK285 is an airburst grenade that can be fired from certain 40 mm belt-fed automatic grenade launchers. The grenade was designed for the Mk 47 Striker. The Mk 47 is a candidate for replacing the Mk 19 grenade launcher, first fielded in 1968, and still in widespread service, around the world. The Mk 47 is considerably lighter than the Mk 19, is designed to fire all the same suite of grenades as the Mk 19, together with more modern grenades the Mk 19 could not fire with full functionality, like the MK285 grenade. The MK285 contains a programmable fuse, initially designed by Bofors but finalized by Nammo, that sets the distance at which the grenade will explode, when the weapon's trigger is pulled. The weapon's computerized sight will have measured the distance to the target the gunner was aiming at, and that distance will be transferred to the grenade's fuse. The munition spins, on its way to the target, and the fuse counts rotations to measure the distance travelled. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Grenade Launcher
A grenade launcher is a weapon that fires a specially-designed large-caliber projectile, often with an explosive, smoke or gas warhead. Today, the term generally refers to a class of dedicated firearms firing unitary grenade cartridges. The most common type are man-portable, shoulder-fired weapons issued to individuals, although larger crew-served launchers are issued at higher levels of organisation by military forces. Grenade launchers can either come in the form of standalone weapons (either single-shot or repeating) or attachments mounted to a parent firearm, usually a rifle. Larger crew-served automatic grenade launchers such as the Mk 19 are mounted on tripods or vehicles. Some armored fighting vehicles also mount fixed arrays of short range, single-shot grenade launchers as a means of defense. History Early precursors The earliest devices which could be referred to as grenade launchers were slings, which could be used to throw early ''grenado'' fuse bombs. The ...

Air Burst
An air burst or airburst is the detonation of an explosive device such as an anti-personnel artillery shell or a nuclear weapon in the air instead of on contact with the ground or target. The principal military advantage of an air burst over a ground burst is that the energy from the explosion (as well as any shell fragments) is distributed more evenly over a wider area; however, the peak energy is lower at ground zero. History Air burst artillery has a long history. The shrapnel shell was invented by Henry Shrapnel of the British Army in about 1780 to increase the effectiveness of canister shot. It was widely used by the time of the War of 1812 and stayed in use until it was superseded during the First World War. Modern shells, though sometimes called "shrapnel shells", actually produce fragments and splinters, not shrapnel. Air bursts were used in the First World War to shower enemy positions and men with shrapnel balls to kill the largest possible number with a sing ...
