QF 6-pounder 6 Cwt Hotchkiss
The Ordnance QF 6-pounder 6 cwt Hotchkiss Mk I and Mk II was a shortened version of the original QF 6 pounder Hotchkiss, QF 6 pounder Hotchkiss naval gun, and was developed specifically for use in the sponsons of the later Marks of British tanks in World War I, from Mark IV tank, Mark IV onwards. History World War I The original QF 6 pounder Hotchkiss, QF 6 pounder naval gun had turned out to be too long for practical use with the current British heavy tank designs, which mounted guns in sponsons on the side rather than turrets on top as modern tanks do. The Muzzle (firearm), muzzles of the long barrels sometimes dug into the mud or struck obstacles when the vehicle crossed Trench warfare, trenches or shell craters. The shortened QF 6 pounder 6 cwt Mk I of single tube construction was introduced in January 1917 in the Mark IV tank, and may be considered the world's first specialised tank gun. The shortened barrel incurred a reduction in muzzle velocity, but as tank guns in World ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
World War I
World War I (28 July 1914 11 November 1918), often abbreviated as WWI, was one of the deadliest global conflicts in history. Belligerents included much of Europe, the Russian Empire, the United States, and the Ottoman Empire, with fighting occurring throughout Europe, the Middle East, Africa, the Pacific, and parts of Asia. An estimated 9 million soldiers were killed in combat, plus another 23 million wounded, while 5 million civilians died as a result of military action, hunger, and disease. Millions more died in genocides within the Ottoman Empire and in the 1918 influenza pandemic, which was exacerbated by the movement of combatants during the war. Prior to 1914, the European great powers were divided between the Triple Entente (comprising France, Russia, and Britain) and the Triple Alliance (containing Germany, Austria-Hungary, and Italy). Tensions in the Balkans came to a head on 28 June 1914, following the assassination of Archduke Franz Ferdin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tank Guns Of The United Kingdom
A tank is an armoured fighting vehicle intended as a primary offensive weapon in front-line ground combat. Tank designs are a balance of heavy firepower, strong armour, and good battlefield mobility provided by tracks and a powerful engine; usually their main armament is mounted in a turret. They are a mainstay of modern 20th and 21st century ground forces and a key part of combined arms combat. Modern tanks are versatile mobile land weapons platforms whose main armament is a large- caliber tank gun mounted in a rotating gun turret, supplemented by machine guns or other ranged weapons such as anti-tank guided missiles or rocket launchers. They have heavy vehicle armour which provides protection for the crew, the vehicle's munition storage, fuel tank and propulsion systems. The use of tracks rather than wheels provides improved operational mobility which allows the tank to overcome rugged terrain and adverse conditions such as mud and ice/snow better than wheeled vehicl ...

World War I Artillery Of The United Kingdom
In its most general sense, the term "world" refers to the totality of entities, to the whole of reality or to everything that is. The nature of the world has been conceptualized differently in different fields. Some conceptions see the world as unique while others talk of a "plurality of worlds". Some treat the world as one simple object while others analyze the world as a complex made up of many parts. In ''scientific cosmology'' the world or universe is commonly defined as " e totality of all space and time; all that is, has been, and will be". '' Theories of modality'', on the other hand, talk of possible worlds as complete and consistent ways how things could have been. ''Phenomenology'', starting from the horizon of co-given objects present in the periphery of every experience, defines the world as the biggest horizon or the "horizon of all horizons". In ''philosophy of mind'', the world is commonly contrasted with the mind as that which is represented by the mind. ''Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Tank Main Guns ...
This is a list of tank main guns which are designed or used as the primary weapon of combat by tanks, such as light tanks, medium tanks, heavy tanks, or main battle tanks. Many tanks have other, secondary weapons installed in them, such as machine guns, autocannons and small calibre mortars, which are not included in this list. Also excluded from this list are weapons installed in self-propelled artillery vehicles such as assault guns or tank destroyers that usually lack turrets. This is due to the unique nature of turreted tank tactics, their design, and operation.

Ordnance QF 2-pounder
The Ordnance QF 2-pounder ( QF denoting "quick firing"), or simply "2 pounder gun", was a British anti-tank gun and vehicle-mounted gun employed in the Second World War. It was the main anti-tank weapon of the artillery units in the Battle of France and, due to the need to rearm quickly after the Dunkirk evacuation, remained in service during the North African campaign. In its vehicle-mounted variant the 2-pounder was a common main gun on British tanks early in World War II, as well as being a typical main armament of armoured cars, such as the Daimler, throughout the war. As the armour protection of Axis tanks improved, the 2-pounder lost effectiveness and it was gradually replaced by the 57 mm QF 6-pounder starting in 1942. It equipped infantry battalion anti-tank platoons replacing their anti-tank rifles until in turn replaced by 6-pounders but remained in service until the end of the war. This QF 2-pounder was distinctly different from the QF 2 pounder "pom-pom" gun ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
British Hardened Field Defences Of World War II
British hardened field defences of World War II were small fortified structures constructed as a part of British anti-invasion preparations. They were popularly known as '' pillboxes'', a reference to their shape. Design and development In May 1940, the directorate of Fortifications and Works (FW3) was set up at the War Office under the direction of Major-General G. B. O. Taylor. Its purpose was to provide a number of basic but effective pillbox designs that could be constructed by soldiers and local labour at appropriate defensive locations. In the following June and July, FW3 issued six basic designs for rifle and light machine gun, designated Type 22 to Type 27. In addition, there were designs for gun emplacements suitable for either the Ordnance QF 2 pounder or the Hotchkiss 6pdr gun (designated Type 28) and a design for a hardened medium machine gun emplacement. There were also designs for pillbox-like structures for various purposes including light anti-aircraft positio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pillbox (military)
A pillbox is a type of blockhouse, or concrete dug-in guard-post, normally equipped with loopholes through which defenders can fire weapons. It is in effect a trench firing step, hardened to protect against small-arms fire and grenades, and raised to improve the field of fire. The modern concrete pillbox originated on the Western Front of World War I, in the German Army in 1916. Etymology The origin of the term is disputed. It has been widely assumed to be a jocular reference to the perceived similarity of the fortifications to the cylindrical and hexagonal boxes in which medical pills were once sold; also, the first German concrete pillboxes discovered by the Allies in Belgium were so small and light that they were easily tilted or turned upside down by the nearby explosion of even medium (240mm) shells. However, it seems more likely that it originally alluded to pillar boxes, with a comparison being drawn between the loophole on the pillbox and the letter-slot ...

British Anti-invasion Preparations Of The Second World War
British anti-invasion preparations of the Second World War entailed a large-scale division of military and civilian mobilisation in response to the threat of invasion (Operation Sea Lion) by German armed forces in 1940 and 1941. The British Army needed to recover from the defeat of the British Expeditionary Force in France, and 1.5 million men were enrolled as part-time soldiers in the Home Guard. The rapid construction of field fortifications transformed much of the United Kingdom, especially southern England, into a prepared battlefield. Sea Lion was never taken beyond the preliminary assembly of forces. Today, little remains of Britain's anti-invasion preparations, although reinforced concrete structures such as pillboxes and anti-tank cubes can still be commonly found, particularly in the coastal counties. Political and military background On 1 September 1939, Germany invaded Poland; two days later, Britain and France declared war on Germany, launching the Second Worl ...

Polish Armoured Trains In Britain
During World War II, 12 Polish armoured trains in Britain were manned, from October 1940 until 1942, by the Polish Armed Forces in the West. They were assigned to patrol the British railways in 1940. They saw no combat and were disbanded in England by July 1943 (November 1944 in Scotland).Zbigniew Lalak, ''Bron pancerna w PSZ 1939–1945.'' pp. 31–38 The trains were built in the Derby Carriage and Wagon Works and the LNER works at Stratford in London. They patrolled the British coast from Cornwall up to the Moray Firth in Scotland. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trench Warfare
Trench warfare is a type of land warfare using occupied lines largely comprising military trenches, in which troops are well-protected from the enemy's small arms fire and are substantially sheltered from artillery. Trench warfare became archetypically associated with World War I (1914–1918), when the Race to the Sea rapidly expanded trench use on the Western Front starting in September 1914.. Trench warfare proliferated when a revolution in firepower was not matched by similar advances in mobility, resulting in a grueling form of warfare in which the defender held the advantage. On the Western Front in 1914–1918, both sides constructed elaborate trench, underground, and dugout systems opposing each other along a front, protected from assault by barbed wire. The area between opposing trench lines (known as " no man's land") was fully exposed to artillery fire from both sides. Attacks, even if successful, often sustained severe casualties.

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] |
