Medium Mark II
The Vickers Medium Mark II was a British tank built by Vickers in the Interbellum, Inter-war period. The Medium Mark II, derived from the Vickers Medium Mark I, was developed to replace the last of the Medium Mark Cs still in use. Production and rebuilding ran from 1925 until 1934. The tank was phased out of service from 1939, replaced by the Cruiser Mk I. It featured several improvements over the Vickers Mark I: a higher superstructure with the driver's visor on top of it instead of in front of it; an improved suspension protected by armour skirts; and Rackham clutches, providing a primitive form of mechanical servo-control. Due to a slightly higher weight its rated speed was somewhat slower than that of the Medium Mark I, at compared to . Design The Mark II used the same chassis, suspension and transmission as the Medium Mark I but had a new superstructure. The Mark II was equipped with a 47 mm 3 pdr gun and four machine guns in the turret. The back of the turret had a s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

7th Armoured Division (United Kingdom)
The 7th Armoured Division was an armoured division of the British Army that saw distinguished active service during the Second World War, where its exploits in the Western Desert Campaign gained it the ''Desert Rats'' nickname. After the Munich Agreement, the division was formed in Egypt during 1938 as the Mobile Division (Egypt) and its first divisional commander was the tank theorist Major-General Sir Percy Hobart. In February 1940, the name of the unit was changed to the 7th Armoured Division. The division fought in most major battles during the North African Campaign; later it would land and fight in the Italian Campaign during the early stages of the invasion of Italy before being withdrawn to the United Kingdom where it prepared to fight in North-west Europe. It began landing in Normandy during the afternoon of D-Day, 6 June 1944, and fought its way across Europe ending the war in Kiel and Hamburg, Germany. Although the division was disbanded during the 1950s, th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Continuation War
The Continuation War, also known as the Second Soviet-Finnish War, was a conflict fought by Finland and Nazi Germany against the Soviet Union from 1941 to 1944, as part of World War II.; sv, fortsättningskriget; german: Fortsetzungskrieg. According to Finnish historian Olli Vehviläinen, the term 'Continuation War' was created at the start of the conflict by the Finnish government, to justify the invasion to the population as a continuation of the defensive Winter War and separate from the German war effort. He titled the chapter addressing the issue in his book as "Finland's War of Retaliation". Vehviläinen asserted that the reality of that claim changed when the Finnish forces crossed the 1939 frontier and started annexation operations. The US Library of Congress catalogue also lists the variants War of Retribution and War of Continuation (see authority control)., group="Note" In Soviet historiography, the war was called the Finnish Front of the Great Patriotic War..

British Raj
The British Raj (; from Hindi ''rāj'': kingdom, realm, state, or empire) was the rule of the British Crown on the Indian subcontinent; * * it is also called Crown rule in India, * * * * or Direct rule in India, * Quote: "Mill, who was himself employed by the British East India company from the age of seventeen until the British government assumed direct rule over India in 1858." * * and lasted from 1858 to 1947. * * The region under British control was commonly called India in contemporaneous usage and included areas directly administered by the United Kingdom, which were collectively called British India, and areas ruled by indigenous rulers, but under British paramountcy, called the princely states. The region was sometimes called the Indian Empire, though not officially. As ''India'', it was a founding member of the League of Nations, a participating nation in the Summer Olympics in 1900, 1920, 1928, 1932, and 1936, and a founding member of the United Nations in San F ...

QF 6 Pounder Hotchkiss
The Ordnance QF Hotchkiss 6 pounder gun Mk I and Mk II or QF 6 pounder 8 cwt were a family of long-lived light naval guns introduced in 1885 to defend against new, small and fast vessels such as torpedo boats and later submarines. There were many variants produced, often under license which ranged in length from 40 to 58 calibers, but 40 caliber was the most common version. 6-pounders were widely used by the navies of a number of nations and often used by both sides in a conflict. Due to advances in torpedo delivery and performance, 6-pounder guns were rapidly made obsolete and were replaced with larger guns aboard most larger warships. This led to their being used ashore during World War I as coastal defense guns, the first tank guns and as anti-aircraft guns, whether on improvised or specialized HA/LA mounts. During World War II 6-pounder guns were put back in service to arm small warships and as coastal defense guns. The last ships to carry 6-pounders were the Aegir-cl ...

Sunbeam Cossack
The Sunbeam Cossack was a British 12-cylinder aero engine that was first run in 1916. The Cossack spawned a family of engines from Sunbeam. Design and development As the First World War raged through 1914 and 1915, The Admiralty demanded engines with more power for its existing and future aircraft. The problem was exemplified by the Short Type 184 seaplanes of the RNAS, powered by Sunbeam Mohawk engines, which could barely lift the standard air-dropped torpedo with crew reduced to two and minimal fuel. An engine with a base rating of at least was demanded by the Admiralty. Responses came from Rolls-Royce with the Rolls-Royce Eagle and Sunbeam with the Sunbeam Cossack. Louis Coatalen designed the Cossack as a twin overhead camshaft 60° V-12, with four valves per cylinder, bore of and stroke of . Output from the Cossack was at 2,000rpm, with a running weight of , driving a large diameter propeller through a 2:1 reduction gear. Construction of the Cossack was largely of al ...

Irish Free State
The Irish Free State ( ga, Saorstát Éireann, , ; 6 December 192229 December 1937) was a state established in December 1922 under the Anglo-Irish Treaty of December 1921. The treaty ended the three-year Irish War of Independence between the forces of the Irish Republic – the Irish Republican Army (IRA) – and British Crown forces. The Free State was established as a dominion of the British Empire. It comprised 26 of the 32 counties of Ireland. Northern Ireland, which was made up of the remaining six counties, exercised its right under the Treaty to opt out of the new state. The Free State government consisted of the Governor-General – the representative of the king – and the Executive Council (cabinet), which replaced both the revolutionary Dáil Government and the Provisional Government set up under the Treaty. W. T. Cosgrave, who had led both of these administrations since August 1922, became the first President of the Executive Council (prime minister). The ...

Asbestos
Asbestos () is a naturally occurring fibrous silicate mineral. There are six types, all of which are composed of long and thin fibrous crystals, each fibre being composed of many microscopic "fibrils" that can be released into the atmosphere by abrasion and other processes. Inhalation of asbestos fibres can lead to various dangerous lung conditions, including mesothelioma, asbestosis, and lung cancer, so it is now notorious as a serious health and safety hazard. Archaeological studies have found evidence of asbestos being used as far back as the Stone Age to strengthen ceramic pots, but large-scale mining began at the end of the 19th century when manufacturers and builders began using asbestos for its desirable physical properties. Asbestos is an excellent electrical insulator and is highly fire-resistant, so for much of the 20th century it was very commonly used across the world as a building material, until its adverse effects on human health were more widely acknowledged ...

Bunker
A bunker is a defensive military fortification designed to protect people and valued materials from falling bombs, artillery, or other attacks. Bunkers are almost always underground, in contrast to blockhouses which are mostly above ground. They were used extensively in World War I, World War II, and the Cold War for weapons facilities, command and control centers, and storage facilities. Bunkers can also be used as protection from tornadoes. Trench bunkers are small concrete structures, partly dug into the ground. Many artillery installations, especially for coastal artillery, have historically been protected by extensive bunker systems. Typical industrial bunkers include mining sites, food storage areas, dumps for materials, data storage, and sometimes living quarters. When a house is purpose-built with a bunker, the normal location is a reinforced below-ground bathroom with fiber-reinforced plastic shells. Bunkers deflect the blast wave from nearby explosions to prevent ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
