L9A1 51 Mm Light 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 The fuze remains unarmed until the pin is withdrawn.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 today is usually a simple, lightweight, man-portable, Muzzleloader, muzzle-loaded cannon, consisting of a Smoothbore, smooth-bore (although some models use a Rifling, rifled barrel) metal tube fixed to a base plate (to spread out the recoil) with a lightweight bipod mount and a Sight (device), sight. Mortars are typically used as indirect fire weapons for close fire support with a variety of ammunition. Historically mortars were heavy Siege, siege artillery. Mortars launch explosive shell (projectile), shells (technically called Bomb, bombs) in high arching Projectile motion, ballistic trajectories. History Mortars have been used for hundreds of years. The earliest reported use of mortars was 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. Ch'oe Hae-san (1380–1443), the son of Ch'oe Mu-sŏn (1325–1395), is generally credited with inventi ...

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. UORs supplement the MOD's long-term planned procurement programme, and are funded by extra Treasury money. 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 include: * L129A1 Sharpshooter rifle – procured when British Army operations in Afghanistan found units required accuracy and lethality at ranges beyond that of the standard-issue L85A2 rifle. * MTP Camouflage ...

Cold War Artillery Of The United Kingdom
Cold is the presence of low temperature, especially in the atmosphere. In common usage, cold is often a subjective perception. A lower bound to temperature is absolute zero, defined as 0.00K on the Kelvin scale, an absolute thermodynamic temperature scale. This corresponds to on the Celsius scale, on the Fahrenheit scale, and on the Rankine scale. Since temperature relates to the thermal energy held by an object or a sample of matter, which is the kinetic energy of the random motion of the particle constituents of matter, an object will have less thermal energy when it is colder and more when it is hotter. If it were possible to cool a system to absolute zero, all motion of the particles in a sample of matter would cease and they would be at complete rest in the classical sense. The object could be described as having zero thermal energy. Microscopically in the description of quantum mechanics, however, matter still has zero-point energy even at absolute zero, because ...

Infantry Mortars
Infantry, or infantryman are a type of soldier who specialize in ground combat, typically fighting dismounted. Historically the term was used to describe foot soldiers, i.e. those who march and fight on foot. In modern usage, the term broadly encompasses a wide variety of subspecialties, including light infantry, irregular infantry, heavy infantry, mountain infantry, motorized infantry, mechanized infantry, airborne infantry, air assault infantry, and naval infantry. Other subtypes of infantry, such as line infantry and mounted infantry, were once commonplace but fell out of favor in the 1800s with the invention of more accurate and powerful weapons. Etymology and terminology In English, use of the term ''infantry'' began about the 1570s, describing soldiers who march and fight on foot. The word derives from Middle French , from older Italian (also Spanish) ''infanteria'' (foot soldiers too inexperienced for cavalry), from Latin '' īnfāns'' (without speech, newborn, ...

LGI Mle F1
The LGI Mle F1 (''Lance-grenade individuel Mle F1'', "individual grenade launcher Model F1") is a lightweight, close-support infantry weapon designed to be used by one man to provide indirect fire. The LGI has been used by the French Army since the 1990s and fires high explosive, smoke, and illumination rounds. Deployment French squads include a 300 Meter fireteam called "Équipe Alpha" (consisting of a team leader armed with a Heckler & Koch HK416 and two grenadiers-voltigeurs, each armed with a Heckler & Koch HK416 assault rifle as well as an AT4 anti-tank weapon) and a 600 Meter fireteam or "Équipe Bravo" (again with a team leader equipped with Heckler & Koch HK416 and two grenadiers-voltigeurs as well with one armed with a FN Minimi light machine gun and the other with both a Heckler & Koch HK416 and LGI). Operation The launcher uses a closed combustion chamber to capture the propulsion gases. The propellant charge is inserted into the tail of each round and transmits an ign ...

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 Dust explosion, grain dust * pressure, pressurized gas compressor, gas, such as a gas cylinder, aerosol can, or boiling liquid expanding vapor explosion * nuclear weapon, 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 ...

Fuze
In military munitions, a fuze (sometimes fuse) is the part of the device that initiates its 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 deton ...

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 a ...

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 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 2025. The A3 variant was first issued in 2018 with several new improvements. The remainder of the SA80 family consists of 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.
