Army Air Service
The United States Army Air Service (USAAS)Craven and Cate Vol. 1, p. 9 (also known as the ''"Air Service"'', ''"U.S. Air Service"'' and before its legislative establishment in 1920, the ''"Air Service, United States Army"'') was the aerial warfare service component of the United States Army between 1918 and 1926 and a forerunner of the United States Air Force. It was established as an independent but temporary branch of the U.S. War Department during World War I by two executive orders of President Woodrow Wilson: on May 24, 1918, replacing the Aviation Section, Signal Corps as the nation's air force; and March 19, 1919, establishing a military Director of Air Service to control all aviation activities., p. 149, Appendix 2 Redesignations of the Army Air Arm, 1907–1942. Its life was extended for another year in July 1919, during which time Congress passed the legislation necessary to make it a permanent establishment. The National Defense Act of 1920 assigned the Air Service t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
United States Military Aircraft National Insignia
This is a listing of the nationality markings used by military aircraft of the United States, including those of the U.S. Air Force, U.S. Navy, U.S. Marine Corps, U.S. Coast Guard, U.S. Army and their predecessors. The Civil Air Patrol is also included for the World War II period because it engaged in combat operations (primarily anti-submarine flights) which its July 1946 charter has since explicitly forbidden. History The first military aviation insignias of the United States include a star used by the US Army Signal Corps Aviation Section, seen during the Pancho Villa punitive expedition, just over a year before American involvement in World War I began. The star was painted only on the vertical tail, in either red (the most often used color) or blue (less likely, due to the strictly orthochromatic photography of that era, rendering the red star as a black one in period photos). At the same time, the US Navy was using a blue anchor on the rudders of its seaplanes. Afte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Air Service Command
The atmosphere of Earth is the layer of gases, known collectively as air, retained by Earth's gravity that surrounds the planet and forms its planetary atmosphere. The atmosphere of Earth protects life on Earth by creating pressure allowing for liquid water to exist on the Earth's surface, absorbing ultraviolet solar radiation, warming the surface through heat retention (greenhouse effect), and reducing temperature extremes between day and night (the diurnal temperature variation). By mole fraction (i.e., by number of molecules), dry air contains 78.08% nitrogen, 20.95% oxygen, 0.93% argon, 0.04% carbon dioxide, and small amounts of other gases. Air also contains a variable amount of water vapor, on average around 1% at sea level, and 0.4% over the entire atmosphere. Air composition, temperature, and atmospheric pressure vary with altitude. Within the atmosphere, air suitable for use in photosynthesis by terrestrial plants and breathing of terrestrial animals is found only in E ...

Combat Arms
Combat arms (or fighting arms in non-American parlance) are troops within national armed forces who participate in direct tactical ground combat. In general, they are units that carry or employ weapons, such as infantry, cavalry, and artillery units. The use of multiple combat arms in mutually supporting ways is known as combined arms. In some armies, notably the British Army, artillery and combat engineer units are categorized as combat support, while in others, such as the U.S. Army and Canadian Army, they are considered part of the combat arms. Armored troops constitute a combat arm in name, although many have histories derived from cavalry units. Artillery is included as a combat arm primarily based on the history of employing cannons in close combat, and later in the anti-tank role until the advent of anti-tank guided missiles. The inclusion of special forces in some armed forces as a separate combat arm is often doctrinal because the troops of special forces units are essent ...

Declaration Of War
A declaration of war is a formal act by which one state (polity), state announces existing or impending war activity against another. The declaration is a performative speech act (or the signing of a document) by an authorized party of a national government, in order to create a state of war between two or more Sovereign state, states. The legality of who is competent to declare war varies between nations and forms of government. In many nations, that power is given to the head of state or monarch, sovereign. In other cases, something short of a full declaration of war, such as a letter of marque or a covert operation, may authorise war-like acts by privateers or mercenary, mercenaries. The official international protocol for declaring war was defined in the Hague Conventions of 1899 and 1907, Hague Convention (III) of 1907 on the Opening of Hostilities. Since 1945, developments in international law such as the United Nations Charter, which prohibits both the threat and the use ...

Table (parliamentary Procedure)
In parliamentary procedure, the verb to table has the opposite meaning in the United States from that of the rest of the world: *In the United States, to "table" usually means to postpone or suspend consideration of a pending motion. *In the rest of the English-speaking world, to "table" means to begin consideration (or reconsideration) of a proposal. Motions which use the word "table" have specific meanings and functions, depending on the parliamentary authority used. The meaning of "table" also depends on the context in which it is used. Difference between American and British usage Both the American and the British dialects have the expression "to table a topic" as a short way of saying "to lay a topic on the table" and "to make a topic lie on the table", but these have opposite meanings in the different varieties of the languages. The British meaning is based on the idea of parliamentarians gathering around a table with the bill laid upon so that all may point to sections for ...

United States Army Air Corps
The United States Army Air Corps (USAAC) was the aerial warfare service component of the United States Army between 1926 and 1941. After World War I, as early aviation became an increasingly important part of modern warfare, a philosophical rift developed between more traditional ground-based army personnel and those who felt that aircraft were being underutilized and that air operations were being stifled for political reasons unrelated to their effectiveness. The USAAC was renamed from the earlier United States Army Air Service on 2 July 1926, and was part of the larger United States Army. The Air Corps became the United States Army Air Forces (USAAF) on 20 June 1941, giving it greater autonomy from the Army's middle-level command structure. During World War II, although not an administrative echelon, the Air Corps (AC) remained as one of the combat arms of the Army until 1947, when it was legally abolished by legislation establishing the Department of the Air Force.

Billy Mitchell
William Lendrum Mitchell (December 29, 1879 – February 19, 1936) was a United States Army officer who is regarded as the father of the United States Air Force. Mitchell served in France during World War I and, by the conflict's end, commanded all American air combat units in that country. After the war, he was appointed deputy director of the Air Service and began advocating increased investment in air power, believing that this would prove vital in future wars. He argued particularly for the ability of bombers to sink battleships and organized a series of bombing runs against stationary ships designed to test the idea. He antagonized many administrative leaders of the Army with his arguments and criticism and in 1925, his temporary appointment as a brigadier general was not renewed, and he reverted to his permanent rank of colonel, due to his insubordination. Later that year, he was court-martialed for insubordination after accusing Army and Navy leaders of an "almost trea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Unity Of Command
In military organisation, unity of command is the principle that subordinate members of a structure should all be responsible to a single commander. United States The military of the United States considers unity of command as one of the twelve principles of joint operations: Military problems When the principle of unity of command is violated problems quickly develop. An example occurred in Afghanistan in 2006 when Combined Forces Command-Afghanistan passed control of the ground fight to the International Security Assistance Force. This caused the operations to split between several unified commanders in charge of U.S. Central Command, the North Atlantic Treaty Organization, and the U.S. Special Operations Command, which caused significant operational problems. See also * Chain of command, a clear command structure * Civilian control of the military * Command hierarchy * Division of labor * Parochialism * Span of control * Staff (military) A military staff or genera ...

Division Of Military Aeronautics
The Division of Military Aeronautics was the name of the aviation organization of the United States Army for a four-day period during World War I. It was created by a reorganization by the War Department of the Aviation Section, U.S. Signal Corps on April 24, 1918, still as part of the Signal Corps. It was removed from the Aviation Section by executive order on May 20, 1918, and existed as the sole Army aviation agency until a War Department general order issued May 24, 1918, established it and the ''Bureau of Aircraft Production'', created by the same reorganization on April 24, as coordinate components of the "Air Service". As such, it is recognized by the United States Air Force as the third of its antecedents. As a subordinate component of the Air Service, the DMA continued until March 19, 1919, when the Board of Aircraft Production was consolidated with it into the Air Service, United States Army.
