Ranging Gun
A spotting rifle or ranging gun is a small-calibre rifle used as a sighting device for artillery. The ballistics of the spotting rifle are matched to those of the artillery piece, so that if a shot from the spotting rifle lands on the target, it may be assumed that the main weapon will also do so. Anti-tank recoilless rifles Spotting rifles were most commonly used with recoilless rifles as anti-tank artillery, from the 1950s to the 1970s. These weapons are used for direct fire with line-of-sight visibility to the target. As recoilless rifles have a relatively low muzzle velocity and thus a high trajectory, accurate ranging is important An optical sight can measure the bearing to a target, but not easily or accurately measure the range. Optical rangefinders were too large for lightweight portable artillery, and the later development of laser rangefinders would in turn make spotting rifles obsolete. The British BAT series of 120 mm anti-tank recoilless rifles used ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marines Firing A 106mm Recoilless Rifle From Classroom In Hue University
Marines, or naval infantry, are typically a military force trained to operate in littoral zones in support of naval operations. Historically, tasks undertaken by marines have included helping maintain discipline and order aboard the ship (reflecting the Impressment, pressed nature of the ship's company and the risk of mutiny), the Boarding (attack), boarding of vessels during combat or capture of Prize (law), prize ships, and providing manpower for Raid (military), raiding Amphibious warfare, ashore in support of the naval objectives. In most countries, the marines are an integral part of that state's navy. The exact term "marine" does not exist in many languages other than English. In French-speaking countries, two terms exist which could be translated as "marine", but do not translate exactly: and ; similar pseudo-translations exist elsewhere, e.g. in Portuguese (). The word ''marine'' means "navy" in many European languages such as Dutch, French, German, Italian and Norwegi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
L6 WOMBAT
The L2 BAT (Battalion, Anti-Tank) was a 120 mm calibre recoilless anti-tank rifle used by the British Army. It was also produced in the MOBAT version without a gun shield, and the ConBAT version with a new spotting rifle attachment. The L6 Wombat version was greatly lightened through the use of magnesium alloys. The Wombat was used by mobile units such as paratroopers and marines. BAT was developed from the wartime Ordnance, RCL, 3.45 in, replacing it and the Ordnance QF 17-pounder to become the standard anti-tank weapon of the Army in the post-World War II era. The BAT and MOBAT were used until anti-tank guided missiles, such as Vigilant and MILAN, took their place. WOMBAT remained in anti-tank platoons in Berlin to supplement MILAN until the late 1980s, due to the expected engagement ranges should the Warsaw Pact have ever attacked. The wire guidance of MILAN would also have been problematic in the built up areas of Berlin. It was envisioned that Wombat would be used in 's ...

Rocket Launcher
A rocket launcher is a weapon that launches an unguided, rocket-propelled projectile. History The earliest rocket launchers documented in imperial China consisted of arrows modified by the attachment of a rocket motor to the shaft a few inches behind the arrowhead. The rocket was propelled by the burning of the black powder in the motor; these should not be confused with early fire arrows, which were conventional arrows carrying small tubes of black powder as an incendiary that ignited only after the arrow hit its target. The rocket launchers were constructed of wood, basketry, and bamboo tubes. The launchers divided the rockets with frames meant to keep them separated, and the launchers were capable of firing multiple rockets at once. Textual evidence and illustrations of various early rocket launchers are found in the 1510 edition of the ''Wujing Zongyao'' translated by Needham and others at Princeton University. (The original ''Wujing Zongyao'' was compiled between 1040 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Type 60 Self-propelled 106 Mm Recoilless Gun
The is a light anti-tank vehicle developed by Japan in the late 1950s. It mounts two M40 106 mm recoilless rifles as its main armament. Development In the mid-1950s the Japan Ground Self-Defense Force contracted for one prototype each from Komatsu (SS1) and Mitsubishi Heavy Industries (SS2) powered by a 110 hp six-cylinder diesel engine and fitted with two recoilless rifles. They were delivered in 1956. A second series of prototypes was built with 4 recoilless rifles, but adoption of the 105mm American M40 recoilless rifle forced the reversion to two weapons. The Type 60 was designed for ambush attacks against enemy tanks, and mounting four weapons gave the vehicle a rather high profile. A third series of three heavier prototypes was built by Komatsu as SS4, with a more powerful engine, a new transmission and clutch and a two-speed auxiliary transmission. They were accepted into service in September 1960. Starting in 1974, a 150 hp Komatsu SA4D105 air-cooled, 4-cyl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Davis Gun
The Davis gun was the first true recoilless gun developed and taken into service. It was developed by Commander Cleland Davis of the United States Navy in 1910, just prior to World War I. Development Davis' design connected two guns back to back, with the backwards-facing gun loaded with lead balls and grease of the same weight as the shell in the other gun, acting as a counter. His idea was used experimentally by the British and Americans as an anti-Zeppelin and anti-submarine weapon mounted on the British Handley Page O/100 and O/400 bombers and the American Curtiss Twin JN and Curtiss HS-2L and H-16 flying boats. The direct development of the gun ended with the end of World War I in November 1918, but the firing principle has been copied by later designs. Description The gun was made in three sizes 2-pounder, 6-pounder and 12-pounder; , , and in caliber respectively, firing , , and shells. The 3-inch gun carried a pressure of 15 tons per square inch (2,109 kg per cm2) whe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Boresight (firearm)
Boresighting is a method of visually pre-aligning a firearm barrel's bore axis with the target, in order to more easily zero the gunsight (optical or iron sights). The process is usually performed on a rifle, and can be accomplished either with the naked eye, or with a specialized device called a boresighter. Optical boresighting Optical boresighting, also referred to as "eyeball boresighting", as the name suggests, involves using the naked eye and the bore axis of a firearm to dial in the sights of a firearm. Based on the type of firearm the procedure for optical bore sighting will vary. For AR style rifles the upper receiver can be dropped from the lower receiver and the bolt carrier group (BCG) can be removed exposing a clear line of sight through the barrel. With the upper receiver fixed in place you can then co-witness thorough the barrel and the sights on the top of the rifle, while doing this you can visually align the bore axis with the sights on a desired target. ...

M50 Ontos
Ontos, officially the Rifle, Multiple 106 mm, Self-propelled, M50, was a U.S. light armored tracked anti-tank vehicle developed in the 1950s. It mounted six 106 mm manually loaded M40 recoilless rifles as its main armament, which could be fired in rapid succession against single targets to increase the probability of a kill. Although the actual caliber of the main guns was 105 mm, it was designated 106 mm to prevent confusion with the ammunition for the 105 mm M27 recoilless rifle, which the M40 replaced. It was produced in limited numbers for the U.S. Marines after the U.S. Army cancelled the project. The Marines consistently reported excellent results when they used the Ontos for direct fire support against infantry in numerous battles and operations during the Vietnam War. The American stock of Ontos was largely expended towards the end of the conflict and the Ontos was removed from service in 1969. Development The ''Ontos'' (Greek for "thing") projec ...

50 BMG
The .50 Browning Machine Gun (.50 BMG, 12.7×99mm NATO and designated as the 50 Browning by the C.I.P.) is a caliber cartridge developed for the M2 Browning heavy machine gun in the late 1910s, entering official service in 1921. Under STANAG 4383, it is a standard service cartridge for NATO forces as well as many non-NATO countries. The cartridge itself has been made in many variants: multiple generations of regular ball, tracer, armor-piercing (AP), incendiary, and saboted sub-caliber rounds. The rounds intended for machine guns are made into a continuous belt using metallic links. The .50 BMG cartridge is also used in anti-materiel rifles. A wide variety of ammunition is available, and the availability of match grade ammunition has increased the usefulness of .50 caliber rifles by allowing more accurate fire than lower quality rounds. History In response to the need for new anti-aircraft weaponry during World War I, John Browning developed the .50 BMG. He wanted the ...

M2 Machine Gun
The M2 machine gun or Browning .50 caliber machine gun (informally, "Ma Deuce") is a heavy machine gun that was designed towards the end of World War I by John Browning. Its design is similar to Browning's earlier M1919 Browning machine gun, which was chambered for the .30-06 cartridge. The M2 uses Browning's larger and more powerful .50 BMG (12.7 mm) cartridge. The design has had many designations; the official U.S. military designation for the current infantry type is Browning Machine Gun, Cal. .50, M2, HB, Flexible. It is effective against infantry, unarmored or lightly armored vehicles and boats, light fortifications, and low-flying aircraft. The gun has been used extensively as a vehicle weapon and for aircraft armament by the United States since the 1930s. It was heavily used during World War II, the Korean War, the Vietnam War, the Falklands War, the Soviet–Afghan War, the Gulf War, the Iraq War, and the War in Afghanistan. It is the primary heavy machine gun of NATO ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
