573d Bombardment Squadron
The 573d Tactical Air Support Squadron is an inactive United States Air Force unit. It was formed by the consolidation of two earlier units bearing the number 573, but has not been active since the consolidation. The first predecessor of the squadron is the 573d Bombardment Squadron, a World War II unit assigned to the 391st Bombardment Group. After training in the United States, the squadron moved to England, and participated in operations against Germany from there and the European Continent as part of IX Bomber Command. It earned a Distinguished Unit Citation for its combat actions. Following V-E Day, the squadron returned to the United States and was inactivated at the port of embarkation. The squadron's second predecessor is the 573d Fighter-Day Squadron, which formed part of the 342d Fighter-Day Wing, when the Air Force reopened Myrtle Beach Air Force Base. A few months after it was activated, the squadron transferred its personnel and equipment to another squadron ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
B-26 Marauder
The Martin B-26 Marauder is an American twin-engined medium bomber that saw extensive service during World War II. The B-26 was built at two locations: Baltimore, Maryland, and Omaha, Nebraska, by the Glenn L. Martin Company. First used in the Pacific Theater of World War II in early 1942, it was also used in the Mediterranean Theater and in Western Europe. After entering service with the United States Army aviation units, the aircraft quickly received the reputation of a " widowmaker" due to the early models' high accident rate during takeoffs and landings. This was because the Marauder had to be flown at precise airspeeds, particularly on final runway approach or when one engine was out. The unusually high 150 mph (241 km/h) speed on short final runway approach was intimidating to many pilots who were used to much slower approach speeds, and when they slowed to speeds below those stipulated in the manual the aircraft would often stall and crash.Ethell 1995, p. 2 ...

Marshalling Yard
A classification yard (American and Canadian English (Canadian National Railway use)), marshalling yard (British, Hong Kong, Indian, Australian, and Canadian English (Canadian Pacific Railway use)) or shunting yard (Central Europe) is a railway yard found at some freight train stations, used to separate railway cars onto one of several tracks. First the cars are taken to a track, sometimes called a ''lead'' or a ''drill''. From there the cars are sent through a series of switches called a ''ladder'' onto the classification tracks. Larger yards tend to put the lead on an artificially built hill called a ''hump'' to use the force of gravity to propel the cars through the ladder. Freight trains that consist of isolated cars must be made into trains and divided according to their destinations. Thus the cars must be shunted several times along their route in contrast to a unit train, which carries, for example, cars from the plant to a port, or coal from a mine to the power plant. ...

Interceptor Aircraft
An interceptor aircraft, or simply interceptor, is a type of fighter aircraft designed specifically for the defensive interception role against an attacking enemy aircraft, particularly bombers and reconnaissance aircraft. Aircraft that are capable of being or are employed as both ‘standard’ air superiority fighters and as interceptors are sometimes known as fighter-interceptors. There are two general classes of interceptor: light fighters, designed for high performance over short range; and heavy fighters, which are intended to operate over longer ranges, in contested airspace and adverse meteorological conditions. While the second type was exemplified historically by specialized night fighter and all-weather interceptor designs, the integration of mid-air refueling, satellite navigation, on-board radar and beyond visual range (BVR) missile systems since the 1960s has allowed most frontline fighter designs to fill the roles once reserved for specialised night/all-weathe ...

Flak
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 aircraf ...

Battle Of The Bulge
The Battle of the Bulge, also known as the Ardennes Offensive, was the last major German offensive (military), offensive military campaign, campaign on the Western Front (World War II), Western Front during World War II. The battle lasted from 16 December 1944 to 28 January 1945, towards the end of the war in Europe. It was launched through the densely forested Ardennes region between Belgium and Luxembourg. The primary military objectives were to deny further use of the Belgian port of Antwerp to the Allies and to split the Allied lines, which potentially could have allowed the Germans to encirclement, encircle and destroy the four Allied forces. Nazi dictator Adolf Hitler, who since December 1941 had assumed direct command of the German army, believed that achieving these objectives would compel the Western Allies to accept a peace treaty in the Axis powers' favor. By this time, it was palpable to virtually the entire German leadership including Hitler himself that they had ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Propaganda
Propaganda is communication that is primarily used to influence or persuade an audience to further an agenda, which may not be objective and may be selectively presenting facts to encourage a particular synthesis or perception, or using loaded language to produce an emotional rather than a rational response to the information that is being presented. Propaganda can be found in news and journalism, government, advertising, entertainment, education, and activism and is often associated with material which is prepared by governments as part of war efforts, political campaigns, health campaigns, revolutionaries, big businesses, ultra-religious organizations, the media, and certain individuals such as soapboxers. In the 20th century, the English term ''propaganda'' was often associated with a manipulative approach, but historically, propaganda has been a neutral descriptive term of any material that promotes certain opinions or ideologies. Equivalent non-English terms have also la ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ammunition Dump
An ammunition dump, ammunition supply point (ASP), ammunition handling area (AHA) or ammunition depot is a military storage facility for live ammunition and explosives. The storage of live ammunition and explosives is inherently hazardous. There is the potential for accidents in the unloading, packing, and transfer of ammunition. Great care is taken in handling these dangerous explosives so as not to harm personnel or nearby ammunition. Despite the intensive preventive measures they get, ammunition depots around the world suffer from non-combat fires and explosions. Although this is a rare occurrence, there are devastating consequences when it does happen. Usually, an ammunition depot experiencing even minor explosions in one of its sites/buildings is immediately evacuated together with surrounding civilian areas. Thus, all of the stored ammunition is left to detonate itself completely for days or weeks, with very limited attempts at firefighting from a safe distance.How one ...

Roye-Amy Airfield
Roye-Amy Airfield is an abandoned World War II military airfield which is located approximately 5 km south-southeast of Roye, approximately 98 km north-northeast of Paris. Originally a 1930s airport which was seized by the Germans during the Battle of France, it was used by the Luftwaffe, then by the United States Army Air Forces during World War II. After the war, the site was abandoned and is now agricultural fields. History Roye-Amy was a pre-World War II airport, with some support buildings, a hangar and grass runways. From September 24, 1939 until 19 May 1940 the RAF 57th BEF group used the airfield for Bristol Blenheim I bombers, where they suffered heavy losses. German use during World War II The airfield was seized by the Germans during the Battle of France. It was not used by the Luftwaffe until May 1941, when Kampfgeschwader 1 (KG 1) was assigned with Junkers Ju 88 medium bombers, which carried out night attacks on England. The bombers remained unti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Saint Lo
In religious belief, a saint is a person who is recognized as having an exceptional degree of holiness, likeness, or closeness to God. However, the use of the term ''saint'' depends on the context and denomination. In Catholic, Eastern Orthodox, Anglican, Oriental Orthodox, and Lutheran doctrine, all of their faithful deceased in Heaven are considered to be saints, but some are considered worthy of greater honor or emulation. Official ecclesiastical recognition, and consequently a public cult of veneration, is conferred on some denominational saints through the process of canonization in the Catholic Church or glorification in the Eastern Orthodox Church after their approval. While the English word ''saint'' originated in Christianity, historians of religion tend to use the appellation "in a more general way to refer to the state of special holiness that many religions attribute to certain people", referring to the Jewish tzadik, the Islamic walī, the Hindu rishi or Sikh ...

Operation Cobra
Operation Cobra was the codename for an Offensive (military), offensive launched by the United States First United States Army, First Army under Lieutenant General Omar Bradley seven weeks after the D-Day landings, during the Invasion of Normandy, Normandy campaign of World War II. The intention was to take advantage of the distraction of the Nazi Germany, Germans by the British and Canadian attacks around Caen in Operation Goodwood,Trew, p. 64 and thereby break through the German defenses that were penning in their forces while the Germans were unbalanced. Once a corridor had been created, the First Army would then be able to advance into Brittany, rolling up the German flanks once free of the constraints of the bocage country. After a slow start, the offensive gathered momentum and German resistance collapsed as scattered remnants of broken units fought to escape to the Seine. Lacking the resources to cope with the situation, the German response was ineffectual and the entire N ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coastal Defence And Fortification
300px, Castillo San Felipe de Barajas in Cartagena de Indias, Colombia, an example of an Early Modern coastal defense Coastal defence (or defense) and coastal fortification are measures taken to provide protection against military attack at or near a coastline (or other shoreline), for example, fortifications and coastal artillery. Because an invading enemy normally requires a port or harbour to sustain operations, such defences are usually concentrated around such facilities, or places where such facilities could be constructed. Coastal artillery fortifications generally followed the development of land fortifications, usually incorporating land defences; sometimes separate land defence forts were built to protect coastal forts. Through the middle 19th century, coastal forts could be bastion forts, star forts, polygonal forts, or sea forts, the first three types often with detached gun batteries called "water batteries". Coastal defence weapons throughout history were heavy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
D-Day
The Normandy landings were the landing operations and associated airborne operations on Tuesday, 6 June 1944 of the Allied invasion of Normandy in Operation Overlord during World War II. Codenamed Operation Neptune and often referred to as D-Day, it was the largest seaborne invasion in history. The operation began the liberation of France (and later western Europe) and laid the foundations of the Allied victory on the Western Front. Planning for the operation began in 1943. In the months leading up to the invasion, the Allies conducted a substantial military deception, codenamed Operation Bodyguard, to mislead the Germans as to the date and location of the main Allied landings. The weather on D-Day was far from ideal, and the operation had to be delayed 24 hours; a further postponement would have meant a delay of at least two weeks, as the invasion planners had requirements for the phase of the moon, the tides, and the time of day that meant only a few days each month were d ...
