It was replaced by the Mk 19 grenade launcher in service with the United States Armed Forces. Design This weapon is a manually-operated, belt-fed. The use of a split breech mechanism allowed the weapon to be light and simple. Employment The Mark 18 was used primarily on small boats or in fixed positions such as bunkers; their primary users were the so-called "river rats" and the SEALs. They could be mounted on M2HB, M60, M1919 tripods, or pintle mounts, but could not be fired without such a mount.

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 operat ...

40×46mm 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 hand, t ...

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 60mm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mobile Riverine Force
In the Vietnam War, the Mobile Riverine Force (MRF) (after May 1967), initially designated Mekong Delta Mobile Afloat Force, and later the Riverines, were a joint US Army and US Navy force that comprised a substantial part of the brown-water navy. It was modeled after lessons learned by the French experience in the First Indochina War of Dinassaut and had the task of both transport (of soldiers and equipment) and combat. The primary base was at Đồng Tâm Base Camp, with a floating base at the base of the Mekong River. It played a key role in the Tet Offensive. Concept of operations The Mekong Delta Mobile Afloat Force was originally conceived as providing an all weather "strike" capability in the Mekong Delta, to actively prosecute contact with Viet Cong units in the Vietnam War. A "strike" force was inherently and essentially different from the existing Navy interdiction and patrol forces (the River Patrol Boats of Operation Game Warden, and the coastal blockade of Operati ...

Armored Troop Carrier (LCM)
Armored Troop Carriers (ATC), often called ''Tangos'' from the phonetic alphabet for ''T'', were LCM-6 landing craft modified for riverine patrol missions. They were used by the Mobile Riverine Force (MRF) of the United States Army and Navy in the Vietnam War. They were also used by Republic of Vietnam Navy (RVNN) and Khmer National Navy. History The MRF began to be organised in late 1966 with the arrival of the 2nd Brigade, 9th Infantry Division at Vung Tau on 19 December 1966. The Navy contribution would be RIVFLOT 1, comprising two river assault squadrons (RAS 9 and RAS 11), each with two river assault divisions under them. The basic mission of RIVFLOT 1 was to transport Army troops to battle zones and support them in battle. The craft the Navy acquired for this task was the ATC, a modified LCM-6. Like its World War II ancestor, it had a large well deck for transporting troops and a drop-down ramp for landing soldiers on a hostile beach. The RVNN had been using LCM variants ...

Pintle
A pintle is a pin or bolt, usually inserted into a gudgeon, which is used as part of a pivot or hinge. Other applications include pintle and lunette ring for towing, and pintle pins securing casters in furniture. Use Pintle/gudgeon sets have many applications, for example: in sailing to hold the rudder onto the boat; in transportation a pincer-type device clamps through a lunette ring on the tongue of a trailer; in controllable solid rocket motors a plug moves into and out of the motor throat to control thrust. In electrical cubicle manufacture, a pintle hinge is a hinge with fixed and moving parts. The hinge has a pin "pintle" and can be both external and internal. The most common type consists of three parts. One part on the body of the cubicle, one part on the door and the third part is the pintle. In transportation, a ''pintle hitch'' is a type of tow hitch that uses a tow ring configuration to secure to a hook or a ball combination for the purpose of towing an unpowered v ...

River Rats
A river is a natural flowing watercourse, usually freshwater, flowing towards an ocean, sea, lake or another river. In some cases, a river flows into the ground and becomes dry at the end of its course without reaching another body of water. Small rivers can be referred to using names such as creek, brook, rivulet, and rill. There are no official definitions for the generic term river as applied to geographic features, although in some countries or communities a stream is defined by its size. Many names for small rivers are specific to geographic location; examples are "run" in some parts of the United States, "burn" in Scotland and northeast England, and "beck" in northern England. Sometimes a river is defined as being larger than a creek, but not always: the language is vague. Rivers are part of the water cycle. Water generally collects in a river from precipitation through a drainage basin from surface runoff and other sources such as groundwater recharge, springs, an ...

United States Armed Forces
The United States Armed Forces are the military forces of the United States. The armed forces consists of six service branches: the Army, Marine Corps, Navy, Air Force, Space Force, and Coast Guard.
