Mark IX Tank
The Mark IX tank was a British armoured fighting vehicle from the First World War. It was the world's first specialised armoured personnel carrier (APC). Development During the first actions with tanks, it became clear that infantry often could not keep up with the tanks; not because soldiers were too slow—the early tanks themselves could only move at a walking pace—but because soldiers on foot remained vulnerable to machine gun fire, though tanks had been invented to solve that problem. On many occasions, positions gained at great cost were immediately lost for lack of infantry to consolidate. It was thought this problem might be solved by cramming a few infantry soldiers into each tank, but the atmosphere inside was of such poor quality that the soldiers became ill and eventually lost consciousness. When exposed to fresh air again, the crew were incapacitated for about an hour while recovering from the noxious fumes inside the tank. They would be sick and suffer from severe ...

Mark VIII Tank
The Mark VIII tank also known as the Liberty or The International was a British-American tank design of the First World War intended to overcome the limitations of the earlier British designs and be a collaborative effort to equip France, the UK and the US with a single heavy tank design. Production at a site in France was expected to take advantage of US industrial capacity to produce the automotive elements, with the UK producing the armoured hulls and armament. The planned production levels would have equipped the Allied armies with a very large tank force that would have broken through the German defensive positions in the planned offensive for 1919. In practice, manufacture was slow and only a few vehicles were produced before the end of the war in November 1918. After the war, 100 vehicles assembled in the US were used by the US Army until more advanced designs replaced them in 1932. A few tanks that had not been scrapped by the start of World War II were offered to Cana ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Displacement (ship)
The displacement or displacement tonnage of a ship is its weight. As the term indicates, it is measured indirectly, using Archimedes' principle, by first calculating the volume of water displaced by the ship, then converting that value into weight. Traditionally, various measurement rules have been in use, giving various measures in long tons. Today, tonnes are more commonly used. Ship displacement varies by a vessel's degree of load, from its empty weight as designed (known as "lightweight tonnage") to its maximum load. Numerous specific terms are used to describe varying levels of load and trim, detailed below. Ship displacement should not be confused with measurements of volume or capacity typically used for commercial vessels and measured by tonnage: net tonnage and gross tonnage. Calculation The process of determining a vessel's displacement begins with measuring its draft.George, 2005. p.5. This is accomplished by means of its "draft marks" (or "load lines"). A ...

Dollis Hill
Dollis Hill is an area in northwest London, which consists of the streets surrounding the 35 hectares (86 acres) Gladstone Park. It is served by a London Underground station, Dollis Hill, on the Jubilee line, providing good links to central London. It is in the London Borough of Brent, close to Willesden Green, Neasden and Cricklewood, and is in the postal districts of NW2 and NW10. The area is mainly residential (Edwardian terraced and 1920s/30s semi-detached houses) with a restaurant, greengrocer and convenience stores near the underground station. The Dollis Hill ward has the highest Irish population in London. Dollis Hill played a part in the Second World War as the code-breaking computer used at Bletchley Park was built at the Post Office Research Station in Dollis Hill and the rarely used alternative Cabinet War Room bunker for Winston Churchill's government was dug underground here. History The Dollis Hill Estate was formed in the early 19th century, when ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Armour
Armour (British English) or armor (American English; see spelling differences) is a covering used to protect an object, individual, or vehicle from physical injury or damage, especially direct contact weapons or projectiles during combat, or from a potentially dangerous environment or activity (e.g. cycling, construction sites, etc.). Personal armour is used to protect soldiers and war animals. Vehicle armour is used on warships, armoured fighting vehicles, and some mostly ground attack combat aircraft. A second use of the term ''armour'' describes armoured forces, armoured weapons, and their role in combat. After the development of armoured warfare, tanks and mechanised infantry and their combat formations came to be referred to collectively as "armour". Etymology The word "armour" began to appear in the Middle Ages as a derivative of Old French. It is dated from 1297 as a "mail, defensive covering worn in combat". The word originates from the Old French , itself d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Loophole (firearm)
A loophole is a protected small opening, which allows a firearm to be aimed and discharged, while providing cover and concealment for the rifleman. To prevent detection, the rifle's muzzle should not protrude through the loophole, particularly at night to hide the muzzle flash. Arrowslit The precursor to the loophole for firearms was the arrowslit, which is a narrow aperture in a fortification for an archer to launch arrows or an arbalist to launch crossbow bolts. The earliest use of the arrowslit was alleged to have been by Archimedes during the siege of Syracuse in 214–212 BC. Arrowslits were used in ancient Greek warfare and by the military of ancient Rome. There was a reintroduction of arrowslits during the medieval warfare period at Dover Castle and Framlingham Castle in England and by Richard the Lionheart at Château Gaillard in France.

Infantry Fighting Vehicle
An infantry fighting vehicle (IFV), also known as a mechanized infantry combat vehicle (MICV), is a type of armoured fighting vehicle used to carry infantry into battle and provide direct-fire support. The 1990 Treaty on Conventional Armed Forces in Europe defines an infantry fighting vehicle as "an armoured combat vehicle which is designed and equipped primarily to transport a combat infantry squad, and which is armed with an integral or organic cannon of at least 20 millimeters calibre and sometimes an antitank missile launcher". IFVs often serve both as the principal weapons system and as the mode of transport for a mechanized infantry unit. Infantry fighting vehicles are distinct from armored personnel carriers (APCs), which are transport vehicles armed only for self-defense and not specifically engineered to fight on their own. IFVs are designed to be more mobile than tanks and are equipped with a rapid-firing autocannon or a large conventional gun; they may include sid ...

Left Hand Drive
Left-hand traffic (LHT) and right-hand traffic (RHT) are the practices, in bidirectional traffic, of keeping to the left side or to the right side of the road, respectively. They are fundamental to traffic flow, and are sometimes referred to as the '' rule of the road''. The terms right- and left-hand ''drive'' refer to the position of the driver and the steering wheel in the vehicle and are, in automobiles, the reverse of the terms right- and left-hand ''traffic''. The rule also extends to where on the road a vehicle is to be driven, if there is room for more than one vehicle in the one direction, as well as the side on which the vehicle in the rear overtakes the one in the front. For example, a driver in an LHT country would typically overtake on the right of the vehicle being overtaken. RHT is used in 165 countries and territories, with the remaining 75 countries and territories using LHT. Countries that use left-hand traffic account for about a sixth of the world's land ...

Gainsborough, Lincolnshire
Gainsborough is a market town, inland port and civil parish in the West Lindsey district of Lincolnshire, England. The town population was 20,842 at the 2011 census, and estimated at 23,243 in 2019. It lies on the east bank of the River Trent, north-west of Lincoln, south-west of Scunthorpe, 20 miles south-east of Doncaster and east of Sheffield. It is England's furthest inland port at over 55 miles (90 km) from the North Sea. History King Alfred, Sweyn Forkbeard and Cnut the Great The place-name Gainsborough first appears in the Anglo-Saxon Chronicle of 1013, as ''Gegnesburh'' and ''Gæignesburh''. In the Domesday Book of 1086 it appears as ''Gainesburg'': Gegn's fortified place. It was one of the capital cities of Mercia in the Anglo-Saxon period that preceded Danish rule. Its choice by the Vikings as an administrative centre was influenced by its proximity to the Danish stronghold at Torksey. In 868 King Alfred married Ealhswith (Ealswitha), daughter of Æ ...
