25 Pounder
The Ordnance QF 25-pounder, or more simply 25-pounder or 25-pdr, was the major British field gun and howitzer during the Second World War. Its calibre is 3.45-inch (87.6 mm). It was introduced into service just before the war started, combining both high-angle and direct-fire abilities, a relatively high rate of fire, and a reasonably lethal shell in a highly mobile piece. It remained the British Army's primary artillery field piece well into the 1960s, with smaller numbers serving in training units until the 1980s. Many Commonwealth of Nations countries used theirs in active or reserve service until about the 1970s and ammunition for the weapon is currently being produced by Pakistan Ordnance Factories. Initial production was slow, but by 1945, over 12,000 had been manufactured. The 25-pounder was probably the most outstanding field artillery piece used by British and Commonwealth forces in the Second World War, being durable, easy to operate and versatile.

Gun-howitzer
Gun-howitzer (also referred to as gun howitzer) is a type of artillery weapon that is intended to fulfill both the role of ordinary cannon or field gun, and that of a howitzer. It is thus able to convey both direct and indirect fire. Modern gun-howitzers are usually identified just as howitzers. To be able to serve as a howitzer, gun-howitzers are typically built to achieve at least 60° to 70° of elevation. For effective direct fire, the gun-howitzers typically employ a fairly long gun barrel, usually not shorter than 30 calibres. Its ammunition also has a high muzzle velocity and usually of large calibre ( calibre and greater). History Historically the first gun-howitzer was the French ''canon obusier'' of the mid-19th century. The smooth-bore Canon obusier de 12 was a versatile weapon that quickly replaced both ordinary cannons and howitzers in French service, and became one of the basic types of artillery used by both sides of the American Civil War. Owing to their versal ...

Indo-Pakistani War Of 1971
The Indo-Pakistani War of 1971 was a military confrontation between India and Pakistan that occurred during the Bangladesh Liberation War in East Pakistan from 3 December 1971 until the Pakistani capitulation in Dhaka on 16 December 1971. The war began with Pakistan's Operation Chengiz Khan, consisting of preemptive aerial strikes on 11 Indian air stations. The strikes led to India declaring war on Pakistan, marking their entry into the war for East Pakistan's independence, on the side of Bengali nationalist forces. India's entry expanded the existing conflict with Indian and Pakistani forces engaging on both the eastern and western fronts. Thirteen days after the war started, India achieved a clear upper hand, and the Eastern Command of the Pakistan military signed the instrument of surrender on 16 December 1971 in Dhaka, marking the formation of East Pakistan as the new nation of Bangladesh. Approximately 93,000 Pakistani servicemen were taken prisoner by ...

Howitzer
A howitzer () is a long- ranged weapon, falling between a cannon (also known as an artillery gun in the United States), which fires shells at flat trajectories, and a mortar, which fires at high angles of ascent and descent. Howitzers, like other artillery equipment, are usually organized in a group called a battery. Howitzers, together with long-barreled guns, mortars, and rocket artillery, are the four basic types of modern artillery. Mortars fire at angles of elevation greater than 45°, and are useful for mountain warfare because the projectile could go over obstacles. Cannons fire at low angles of elevation (<45°), and the projectile lands much faster at its target than it would in the case of a mortar. But the cannon is not useful if there is an obstacle like a hill/wall in front of its target.


Etymology

The English word ''howitzer'' comes from the Czech word , from , 'crowd', and is in turn a borrowing from the Middle High German word or (mode ...

Field Gun
A field gun is a field artillery piece. Originally the term referred to smaller guns that could accompany a field army on the march, that when in combat could be moved about the battlefield in response to changing circumstances ( field artillery), as opposed to guns installed in a fort (garrison artillery or coastal artillery), or to siege cannons and mortars which are too large to be moved quickly, and would be used only in a prolonged siege. Perhaps the most famous use of the field gun in terms of advanced tactics was Napoleon Bonaparte's use of very large wheels on the guns that allowed them to be moved quickly even during a battle. By moving the guns from point-to-point during a battle, enemy formations could be broken up to be handled by the infantry or cavalry wherever they were massing, dramatically increasing the overall effectiveness of the attack. World War I As the evolution of artillery continued, almost all guns of any size became capable of being moved at some ...

Hydraulic Recoil Mechanism
A hydraulic recoil mechanism is a way of limiting the effects of recoil and adding to the accuracy and firepower of an artillery piece. Description The usual recoil system in modern quick-firing guns is the hydro-pneumatic recoil system. In this system, the barrel is mounted on rails on which it can recoil to the rear, and the recoil is taken up by a cylinder which is similar in operation to an automotive gas-charged shock absorber, and is commonly visible as a cylinder mounted parallel to the barrel of the gun, but shorter and smaller than it. The cylinder contains a charge of compressed air, as well as hydraulic oil; in operation, the barrel's energy is taken up in compressing the air as the barrel recoils backward, then is dissipated via hydraulic damping as the barrel returns forward to the firing position. The recoil impulse is thus spread out over the time in which the barrel is compressing the air, rather than over the much narrower interval of time when the project ...

Rifled Breech Loader
A rifled breech loader (RBL) is an artillery piece which, unlike the smoothbore cannon and rifled muzzle loader (RML) which preceded it, has rifling in the barrel and is loaded from the breech at the rear of the gun. The spin imparted by the gun's rifling gives projectiles directional stability and increased range. Loading from the rear of the gun leaves the crew less exposed to enemy fire, allows smaller gun emplacements or turrets, and allows a faster rate of fire. Overview The major problem to be solved with breechloading artillery was obturation: the sealing of the breech after firing to ensure that none of the gases generated by the burning of the propellant (initially gunpowder) escaped rearwards through the breech. This was both a safety issue and one of gun performance – all the propellant gas was needed to accelerate the projectile along the barrel. The second problem was speed of operation – how to close the breech before firing and open it after firing as quickly ...

Royal Ordnance
Royal Ordnance plc was formed on 2 January 1985 as a public corporation, owning the majority of what until then were the remaining United Kingdom government-owned Royal Ordnance Factories (abbreviated ROFs) which manufactured explosives, ammunition, small arms including the Lee–Enfield rifle, guns and military vehicles such as tanks. It owned some 16 factories; and employed about 19,000 staff. Royal Ordnance plc was bought by British Aerospace (BAe) in April 1987, which became BAE Systems in 1999. The name Royal Ordnance was retained for almost another twenty years; and the sites retained their former names, either as ''Royal Ordnance'' or later ''RO Defence'' sites. The Royal Ordnance name was dropped in 2004 and after having traded as Land Systems, the division is now known as Land UK. History Royal Ordnance Factories The Royal Ordnance Factories (ROFs) can trace their history back to 1560 with the founding of the Royal Gunpowder Factory (RGPF) at Waltham Abbey, Essex. This ...

Lebanese Civil War
The Lebanese Civil War ( ar, الحرب الأهلية اللبنانية, translit=Al-Ḥarb al-Ahliyyah al-Libnāniyyah) was a multifaceted armed conflict that took place from 1975 to 1990. It resulted in an estimated 120,000 fatalities and an exodus of almost one million people from Lebanon. The diversity of the Lebanese population played a notable role in the lead-up to and during the conflict: Sunni Muslims and Christians comprised the majority in the coastal cities; Shia Muslims were primarily based in the south and the Beqaa Valley in the east; and Druze and Christians populated the country's mountainous areas. The Lebanese government had been run under the significant influence of elites within the Maronite Christian community. The link between politics and religion had been reinforced under the French Mandate from 1920 to 1943, and the country's parliamentary structure favoured a leading position for its Christian-majority population. However, the country had a ...
