Ordnance BLC 15 Pounder
The Ordnance BLC 15-pounder gun (BLC stood for BL Converted) was a modernised version of the obsolete BL 15-pounder 7 cwt gun, incorporating a recoil and recuperator mechanism above the barrel and a modified quicker-opening breech. It was developed to provide Territorial Force artillery brigades with a reasonably modern field gun without incurring the expense of equipping them with the newer 18-pounder. It is the gun that writers usually mean by "15-pounder gun" in World War I, but can be confused with the earlier Ordnance QF 15-pounder ''Ehrhardt'' or Ordnance BL 15-pounder, both of which fired the same shell. Design Many modifications were made to the old BL 15-pounder barrels to adapt them to a new carriage with a recoil buffer and recuperator above the barrel similar to the modern 13-pounder design. Previously, the barrels had been mounted directly on the carriage by trunnions. Now, the barrel was suspended from a forged-steel inverted U-shaped cradle which had trunnion ...

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 so ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trunnion
A trunnion (from Old French "''trognon''", trunk) is a cylindrical protrusion used as a mounting or pivoting point. First associated with cannons, they are an important military development. Alternatively, a trunnion is a shaft that positions and supports a tilting plate. This is a misnomer, as in reality it is a cradle for the true trunnion. In mechanical engineering (see the trunnion bearing section below), it is one part of a rotating joint where a shaft (the trunnion) is inserted into (and turns inside) a full or partial cylinder. Medieval history In a cannon, the trunnions are two projections cast just forward of the center of mass of the cannon and fixed to a two-wheeled movable gun carriage. As they allowed the muzzle to be raised and lowered easily, the integral casting of trunnions is seen by military historians as one of the most important advances in early field artillery. With the creation of larger and more powerful siege guns in the early 15th century, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anti-tank Gun
An anti-tank gun is a form of artillery designed to destroy tanks and other armored fighting vehicles, normally from a static defensive position. The development of specialized anti-tank munitions and anti-tank guns was prompted by the appearance of tanks during World War I. To destroy hostile tanks, artillerymen often used field guns depressed to fire directly at their targets, but this practice expended too much valuable ammunition and was of increasingly limited effectiveness as tank armor became thicker. The first dedicated anti-tank artillery began appearing in the 1920s, and by World War II was a common appearance in many European armies. To penetrate armor, they fired specialized ammunition from longer barrels to achieve a higher muzzle velocity than field guns. Most anti-tank guns were developed in the 1930s as improvements in tanks were noted, and nearly every major arms manufacturer produced one type or another. Anti-tank guns deployed during World War II were often mann ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Western Front (World War I)
The Western Front was one of the main theatres of war during the First World War. Following the outbreak of war in August 1914, the German Army opened the Western Front by invading Luxembourg and Belgium, then gaining military control of important industrial regions in France. The German advance was halted with the Battle of the Marne. Following the Race to the Sea, both sides dug in along a meandering line of fortified trenches, stretching from the North Sea to the Swiss frontier with France, which changed little except during early 1917 and in 1918. Between 1915 and 1917 there were several offensives along this front. The attacks employed massive artillery bombardments and massed infantry advances. Entrenchments, machine gun emplacements, barbed wire and artillery repeatedly inflicted severe casualties during attacks and counter-attacks and no significant advances were made. Among the most costly of these offensives were the Battle of Verdun, in 1916, with a combined 700 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Second Battle Of Ypres
During the First World War, the Second Battle of Ypres was fought from for control of the tactically important high ground to the east and south of the Flemish town of Ypres in western Belgium. The First Battle of Ypres had been fought the previous autumn. The Second Battle of Ypres was the first mass use by Germany of poison gas on the Western Front. Background The eminent German chemist Walther Nernst, who was in the army in 1914 as a volunteer driver, saw how trenches produced deadlock. He proposed to Colonel Max Bauer, the German general staff officer responsible for liaison with scientists, that they could empty the opposing trenches by a surprise attack with tear gas. Observing a field test of this idea, the chemist Fritz Haber instead proposed using heavier-than-air chlorine gas The German commander Erich von Falkenhayn agreed to try the new weapon, but intended to use it in a diversionary attack by his 4th Army. Falkenhayn wanted to use the gas to cover the withdr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Kitchener's Army
The New Army, often referred to as Kitchener's Army or, disparagingly, as Kitchener's Mob, was an (initially) all-volunteer portion of the British Army formed in the United Kingdom from 1914 onwards following the outbreak of hostilities in the First World War in late July 1914. It originated on the recommendation of Herbert Kitchener, then the Secretary of State for War to obtain 500,000 volunteers for the Army. Kitchener's original intention was that these men would be formed into units that would be ready to be put into action in mid-1916, but circumstances dictated the use of these troops before then. The first use in a major action of Kitchener's Army units came at the Battle of Loos (September–October 1915). Origins Contrary to the popular belief that the war would be over by Christmas 1914, Kitchener predicted a long and brutal war. He believed that arrival in Europe of an overwhelming force of new, well-trained and well-led divisions would prove a decisive blow ag ...

Anti-aircraft Warfare
Anti-aircraft warfare, counter-air or air defence forces is the battlespace response to aerial warfare, defined by NATO as "all measures designed to nullify or reduce the effectiveness of hostile air action".AAP-6 It includes surface based, subsurface ( submarine launched), and air-based weapon systems, associated sensor systems, command and control arrangements, and passive measures (e.g. barrage balloons). It may be used to protect naval, ground, and air forces in any location. However, for most countries, the main effort has tended to be homeland defence. NATO refers to airborne air defence as counter-air and naval air defence as anti-aircraft warfare. Missile defence is an extension of air defence, as are initiatives to adapt air defence to the task of intercepting any projectile in flight. In some countries, such as Britain and Germany during the Second World War, the Soviet Union, and modern NATO and the United States, ground-based air defence and air defence airc ...

Zeppelin
A Zeppelin is a type of rigid airship named after the German inventor Count Ferdinand von Zeppelin () who pioneered rigid airship development at the beginning of the 20th century. Zeppelin's notions were first formulated in 1874Eckener 1938, pp. 155–157. and developed in detail in 1893.Dooley 2004, p. A.187. They were patented in Germany in 1895 and in the United States in 1899. After the outstanding success of the Zeppelin design, the word ''zeppelin'' came to be commonly used to refer to all rigid airships. Zeppelins were first flown commercially in 1910 by Deutsche Luftschiffahrts-AG (DELAG), the world's first airline in revenue service. By mid-1914, DELAG had carried over 10,000 fare-paying passengers on over 1,500 flights. During World War I, the German military made extensive use of Zeppelins as bombers and as scouts, resulting in over 500 deaths in bombing raids in Britain. The defeat of Germany in 1918 temporarily slowed the airship business. Although DELAG establi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
