6004th Air Intelligence Service Squadron
The 6004th Air Intelligence Service Squadron was "the first covert (military intelligence) collection agency in the history of the United States Air Force".Haas (2002), p. 58. Begun by Major Donald Nichols as an impromptu extension of his pre-Korean War espionage in 1950, it was first dubbed "Special Activities Unit Number One". In April or May 1951, it officially became the 6004th Air Intelligence Service Squadron. The 6004th was an unorthodox unit that engaged in espionage and aircrew escape and evasion, as well as collecting information. It was Far East Air Force's primary supplier of intelligence for the war, generating as many as 900 reports per month. Preceding activities The origin of the 6004th Air Intelligence Service Squadron lies in the confusion following the start of the Korean War on 25 June 1950. When the North Koreans invaded South Korea, the United States Air Force had no military intelligence units. To fill the need for what he deemed "positive intelligence", C ...

Military Intelligence
Military intelligence is a military discipline that uses information collection and analysis approaches to provide guidance and direction to assist commanders in their decisions. This aim is achieved by providing an assessment of data from a range of sources, directed towards the commanders' mission requirements or responding to questions as part of operational or campaign planning. To provide an analysis, the commander's information requirements are first identified, which are then incorporated into intelligence collection, analysis, and dissemination. Areas of study may include the operational environment, hostile, friendly and neutral forces, the civilian population in an area of combat operations, and other broader areas of interest. Intelligence activities are conducted at all levels, from tactical to strategic, in peacetime, the period of transition to war, and during a war itself. Most governments maintain a military intelligence capability to provide analytical and i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Swept-wing
A swept wing is a wing that angles either backward or occasionally forward from its root rather than in a straight sideways direction. Swept wings have been flown since the pioneer days of aviation. Wing sweep at high speeds was first investigated in Germany as early as 1935 by Albert Betz and Adolph Busemann, finding application just before the end of the Second World War. It has the effect of delaying the shock waves and accompanying aerodynamic drag rise caused by fluid compressibility near the speed of sound, improving performance. Swept wings are therefore almost always used on jet aircraft designed to fly at these speeds. The term "swept wing" is normally used to mean "swept back", but variants include forward sweep, variable sweep wings and oblique wings in which one side sweeps forward and the other back. The delta wing is also aerodynamically a form of swept wing. Reasons for sweep There are three main reasons for sweeping a wing: 1. to arrange the center of gravi ...

Military Units And Formations Established In 1951
A military, also known collectively as armed forces, is a heavily armed, highly organized force primarily intended for warfare. It is typically authorized and maintained by a sovereign state, with its members identifiable by their distinct military uniform. It may consist of one or more military branches such as an army, navy, air force, space force, marines, or coast guard. The main task of the military is usually defined as defence of the state and its interests against external armed threats. In broad usage, the terms ''armed forces'' and ''military'' are often treated as synonymous, although in technical usage a distinction is sometimes made in which a country's armed forces may include both its military and other paramilitary forces. There are various forms of irregular military forces, not belonging to a recognized state; though they share many attributes with regular military forces, they are less often referred to as simply ''military''. A nation's military may ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

MAJCOM Squadrons Of The United States Air Force
This is a list of major commands (MAJCOM) of the United States Air Force. A major command is a significant Air Force organization subordinate to Headquarters, US Air Force. Major commands have a headquarters staff and subordinate organizations, typically formed in numbered air forces, centers, wings, and groups. Historically, a MAJCOM is the highest level of command, only below Headquarters Air Force (HAF), and directly above numbered air forces (NAFs). The USAF is organized on a functional basis in the United States and a geographical basis overseas. A major command (MAJCOM) represents a major Air Force subdivision having a specific portion of the Air Force mission. Each MAJCOM is directly subordinate to Headquarters, Air Force. MAJCOMs are interrelated and complementary, providing offensive, defensive, and support elements. An operational command consists (in whole or in part) of strategic, tactical, or defense forces; or of flying forces that directly support such forces. A su ...

Intelligence Squadrons Of The United States Air Force
Intelligence has been defined in many ways: the capacity for abstraction, logic, understanding, self-awareness, learning, emotional knowledge, reasoning, planning, creativity, critical thinking, and problem-solving. More generally, it can be described as the ability to perceive or infer information, and to retain it as knowledge to be applied towards adaptive behaviors within an environment or context. Intelligence is most often studied in humans but has also been observed in both non-human animals and in plants despite controversy as to whether some of these forms of life exhibit intelligence. Intelligence in computers or other machines is called artificial intelligence. Etymology The word '' intelligence'' derives from the Latin nouns '' intelligentia'' or '' intellēctus'', which in turn stem from the verb '' intelligere'', to comprehend or perceive. In the Middle Ages, the word ''intellectus'' became the scholarly technical term for understanding, and a trans ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aircraft Emergency Frequency
The aircraft emergency frequency (also known as GUARD) is a frequency used on the aircraft band reserved for emergency communications for aircraft in distress. The frequencies are 121.5 MHz for civilian, also known as International Air Distress (IAD) or VHF Guard, and 243.0 MHz—the second harmonic of VHF guard—for military use, also known as Military Air Distress (MAD) or UHF Guard. Earlier emergency locator transmitters (ELTs) used the guard frequencies to transmit, but an additional frequency of 406 MHz is used by a more modern emergency locator transmitter. History The choice of 121.5 MHz was made by ICAO in conjunction with ARINC and the ITU. Monitoring In the United States, the emergency frequency is monitored by most air traffic control towers, FSS services, national air traffic control centers, military air defense and other flight and emergency services, as well as by many commercial aircraft. The notice to airmen FDC 4/4386 requires "…all airc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
McGuire Rig
The McGuire Rig was used to extract soldiers from the jungles of Vietnam. It would be suspended from a helicopter and used to extract soldiers from areas without a suitable pick-up zone. It was simple, inexpensive, and effective. Although less comfortable than the STABO (Short Tactical Air Borne Operations) harness, it did not require the soldiers to carry any special equipment. It was designed by Sergeant Major Charles T. McGuire, a member of Project DELTA, a Special Forces reconnaissance project. The McGuire Rig was fashioned from a wide, long A7A nylon cargo tie-down strap with a quick-fit buckle on one end. This was typically cut down to an length and a web loop (wrist strap) attached near the top end. This was used to form a sling loop and attached to an over length of 5/8-inch nylon rope. Three ropes with McGuire Rigs attached could be dropped from a UH-1 "Huey" helicopter, all on the same side. A deployment pack containing a sandbag carried each rope to the ground. ...

Trench Warfare
Trench warfare is a type of land warfare using occupied lines largely comprising Trench#Military engineering, 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 (World War I), Western Front starting in September 1914.. Trench warfare proliferated when a Weapons of World War I, revolution in firepower was not matched by similar advances in mobility (military), 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 (military), front, protected from assault by barbed wire. The area between opposing trench lines (known as "no man's land") was fully exposed to artillery ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
