Royal Ordnance 51 Mm Infantry Mortar
The L9A1 51 mm light mortar was a man-portable platoon-level mortar used by the British Army from 1988 to 2007. The 51 mm mortar replaced the World War II-vintage 2 inch mortar in the late 1980s. It was due to be phased out by the use of the 40 mm L17A2 underslung grenade launcher (UGL) mounted on the L85A2 service rifle; however operational experience has led to the decision to replace it with a 60mm mortar. The Hirtenberger AG M6-895 60 mm Mortar was procured in 2007 as an Urgent Operational Requirement (UOR) to replace the current 51 mm Mortar on current operations. Design Ammunition for the 51 mm mortar has a small, ring-pull safety pin on the side of the nose-fuze. The fuze remains unarmed until the pin is withdrawn. Therefore, the safety pin must always be removed and discarded before a mortar shell is fired. A short range insert device allows the weapon to be used in a direct fire mode.

Mortar (weapon)
A mortar is usually a simple, lightweight, man-portable, muzzle-loaded weapon, consisting of a smooth-bore (although some models use a rifled barrel) metal tube fixed to a base plate (to spread out the recoil) with a lightweight bipod mount and a sight. They launch explosive shells (technically called bombs) in high-arcing ballistic trajectories. Mortars are typically used as indirect fire weapons for close fire support with a variety of ammunition. History Mortars have been used for hundreds of years. The earliest mortars were used in Korea in a 1413 naval battle when Korean gunsmiths developed the ''wan'gu'' (gourd-shaped mortar) (완구, 碗口). The earliest version of the ''wan'gu'' dates back to 1407. Choi Hae-san (최해산, 崔海山) (1380–1443), the son of Choe Mu-seon (최무선, 崔茂宣) (1325–1395), is generally credited with inventing the ''wan'gu''. In the Ming dynasty, general Qi Jiguang recorded the use of a mini cannon called the Hu dun pao that was simi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
British Army
The British Army is the principal land warfare force of the United Kingdom, a part of the British Armed Forces along with the Royal Navy and the Royal Air Force. , the British Army comprises 79,380 regular full-time personnel, 4,090 Gurkhas, and 28,330 volunteer reserve personnel. The modern British Army traces back to 1707, with antecedents in the English Army and Scots Army that were created during the Restoration in 1660. The term ''British Army'' was adopted in 1707 after the Acts of Union between England and Scotland. Members of the British Army swear allegiance to the monarch as their commander-in-chief, but the Bill of Rights of 1689 and Claim of Right Act 1689 require parliamentary consent for the Crown to maintain a peacetime standing army. Therefore, Parliament approves the army by passing an Armed Forces Act at least once every five years. The army is administered by the Ministry of Defence and commanded by the Chief of the General Staff. The Brit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
British 2 Inch Mortar
The Ordnance SBML two-inch mortar, or more commonly, just "two-inch mortar", was a British mortar issued to the British Army and the Commonwealth armies, that saw use during the Second World War and later. It was more portable than larger mortars, and had greater range and firepower than rifle grenades. Its main purpose was to produce smoke for cover and -through high trajectory and HE shell - engage targets "immune to small arms fire" Design The two-inch mortar was one of a number of small mortars brought into service by European nations between the two World Wars. Due to its small size, and for simplicity, the mortar had no forward strut or bipod like larger designs needed. The barrel was held at the correct angle by one soldier while the other loaded and fired the round. The original design had a large base plate and sights for aiming which used spirit levels. As the design matured, the baseplate became smaller and the sights were omitted. Aiming was by eye and relied on t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
40 Mm Grenade
40 mm grenade (also styled 40mm grenade) is a generic class-name for grenade launcher ammunition ( subsonic shells) in caliber. The generic name stems from the fact that several countries have developed or adopted grenade launchers in 40 mm caliber. This is a general collection of the world's many different "40 mm grenades". NATO NATO currently uses three standardized 40 mm grenade families: 40 mm low velocity (LV), 40 mm medium velocity (MV), and 40 mm high velocity (HV). Low- and medium-velocity cartridges are used for different hand-held grenade launchers, while the high-velocity cartridge is used for automatic grenade launchers. 40×46 mm LV (40 mm low velocity) ''40×46 mm LV'' (''low velocity'') is a NATO-standard high–low grenade launcher cartridge meant for hand-held grenade launchers, such as the M79, M203, Milkor MGL, and Heckler & Koch AG36. The propellant has low pressure and gives the projectile an average velocity of depending on the ammuniti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 grenade launcher, Mk 19 are mounted on trip ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
L85A2
The SA80 (Small Arms for the 1980s) is a British family of 5.56×45mm NATO service weapons used by the British Army. The L85 Rifle variant has been the standard issue service rifle of the British Armed Forces since 1987, replacing the L1A1 Self-Loading Rifle. The first prototypes were created in 1976, with production of the A1 variant starting in 1985 and ending in 1994. The A2 variant came to be as the result of a significant upgrade in the early 2000s by Heckler & Koch and remains in service as of 2020. The A3 variant was first issued in 2018 with several new improvements. The remainder of the SA80 family comprises the L86 Light Support Weapon, the short-barrelled L22 Carbine and the L98 Cadet rifle. The SA80 was the last in a long line of British weapons (including the Lee–Enfield family) to come from the Royal Small Arms Factory, the national arms development and production facility at Enfield Lock, before its weapons factory was closed down in 1988.

M6-640
The M6 Mortar is a 60 mm lightweight infantry mortar made by Hirtenberger AG of Austria. Models The mortar is of traditional design with a smoothbore barrel, round baseplate (350 mm diameter), bipod and sight unit and is generally available in three different ballistical barrel lengths, which is usually stated in the model's name: * 640 mm * 895 mm * 1000 mm Maximum rate of fire with all models is 30 bombs per minute, when loaded by two people alternately, or 12 bombs per minute, when loaded by only one person. Naturally, the maximum ranges differ depending on the ballistic barrel length and the maximal allowed charges. For all three ballistic barrel lengths a conversion kit is available to fire the mortar in a handheld mode (without bipod and sight) as a '' commando mortar''. The conversion kit contains a small round basepiece, an alternate, slightly bigger rectangular basepiece for soft ground, a carrying belt, an aiming device to set the firing range ...

Urgent Operational Requirement
An Urgent Operational Requirement (UOR) is a system used by the British Ministry of Defence (MOD) to obtain urgent equipment for operations. Supplementing the MOD's long term planned equipment programme are Urgent Operational Requirements (UOR), funded by extra Treasury money. Urgent Operational Requirements (UORs) arise from the identification of previously unprovisioned and emerging capability gaps as a result of current or imminent operations or where deliveries under existing contracts for equipment or services require accelerating due to an increased urgency to bring the capability they provided into service. These capability shortfalls are addressed by the urgent procurement of either new or additional equipment, enhancing existing capability, within a time scale that cannot be met by the normal acquisition cycle. Examples of this include; L129A1 Sharpshooter rifle - procured when British Army operations in Afghanistan found that ground units required a weapon platform w ...

Fuze
In military munitions, a fuze (sometimes fuse) is the part of the device that initiates function. In some applications, such as torpedoes, a fuze may be identified by function as the exploder. The relative complexity of even the earliest fuze designs can be seen in cutaway diagrams. A fuze is a device that detonates a munition's explosive material under specified conditions. In addition, a fuze will have safety and arming mechanisms that protect users from premature or accidental detonation. For example, an artillery fuze's battery is activated by the high acceleration of cannon launch, and the fuze must be spinning rapidly before it will function. "Complete bore safety" can be achieved with mechanical shutters that isolate the detonator from the main charge until the shell is fired. A fuze may contain only the electronic or mechanical elements necessary to signal or actuate the detonator, but some fuzes contain a small amount of primary explosive to initiate the detonation. ...

High Explosive
An explosive (or explosive material) is a reactive substance that contains a great amount of potential energy that can produce an explosion if released suddenly, usually accompanied by the production of light, heat, sound, and pressure. An explosive charge is a measured quantity of explosive material, which may either be composed solely of one ingredient or be a mixture containing at least two substances. The potential energy stored in an explosive material may, for example, be * chemical energy, such as nitroglycerin or grain dust * pressurized gas, such as a gas cylinder, aerosol can, or BLEVE * nuclear energy, such as in the fissile isotopes uranium-235 and plutonium-239 Explosive materials may be categorized by the speed at which they expand. Materials that detonate (the front of the chemical reaction moves faster through the material than the speed of sound) are said to be "high explosives" and materials that deflagrate are said to be "low explosives". Explosives may a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
