Transport Helicopter
A military transport aircraft, military cargo aircraft or airlifter is a military-owned transport aircraft used to support military operations by airlifting troops and military equipment. Transport aircraft are crucial to maintaining supply lines to forward bases that are difficult to reach by ground or waterborne access, and can be used for both strategic and tactical missions. They are also often used for civilian emergency relief missions by transporting humanitarian aid. Air frames Fixed-wing Military transport aeroplanes are defined in terms of their range capability as strategic airlift or tactical airlift to reflect the needs of the land forces which they most often support. These roughly correspond to the commercial flight length distinctions: Eurocontrol defines short-haul routes as shorter than , long-haul routes as longer than and medium-haul between. The military glider is an unpowered tactical air transport which has been used in some campaigns to trans ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Military Glider
Military gliders (an offshoot of common gliders) have been used by the militaries of various countries for carrying troops ( glider infantry) and heavy equipment to a combat zone, mainly during the Second World War. These engineless aircraft were towed into the air and most of the way to their target by military transport planes, e.g., C-47 Skytrain or Dakota, or bombers relegated to secondary activities, e.g., Short Stirling. Most military gliders do not soar, although there were attempts to build military sailplanes as well, such as the DFS 228. Once released from the tow craft near the front, they were to land on any convenient open terrain close to the target, hopefully with as little damage to the cargo and crew as possible, as most landing zones (LZ) were far from ideal. The one-way nature of the missions meant that they were treated as semi-expendable leading to construction from common and inexpensive materials such as wood. Most nations seriously attempted to recover ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Door Gunner
A door gunner is a crewman tasked with firing and maintaining manually directed armament aboard a military helicopter. The actual role will vary depending on the task given on a particular mission. For certain aircraft a door gunner would use a fully automatic Gatling gun placement. On many larger aircraft such as military planes a turret is used along with heavy cannons. Origins The concept of the ''door gunner'' originated during the Vietnam War, when helicopters were first used in combat in large numbers. The original personnel who served as early door gunners aboard CH-21, UH-34, and UH-1 helicopters in Vietnam, were enlisted men, with a designated and specially trained '' crew chief'' serving as both the aircraft's maintenance manager and a door gunner. Normally, a second enlisted soldier served as a second door gunner (such as on a UH-1, and UH-34, which both used two gunners – one on each side of the aircraft). Later, as the war progressed, the door gunner posi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Landing Zone
In military terminology a landing zone (LZ) is an area where aircraft can land. In the United States military, a landing zone is the actual point where aircraft, especially helicopters, land (equivalent to the commonwealth landing point.)The Handbook Of The SAS And Elite Forces. How The Professionals Fight And Win. Edited by Jon E. Lewis. p.289-Tactics And Techniques, Landings And Raids On Enemy Territory. Robinson Publishing Ltd 1997. ISBN 1-85487-675-9 In commonwealth militaries, a landing zone is the cartographic (numeric) zone in which the landing is going to take place (e.g., a valley). The landing area is the area in which the landing is going to take place (e.g., the field where the aircraft are to land). The landing point is the actual point on which aircraft are going to land (e.g., a point of the field). Each aircraft has a different landing point. Identifying an LZ from the air Landing areas are most commonly marked by colored smoke. The standard procedure is for troo ...

Section (military Unit)
A section is a military sub-subunit. It usually consists of between 6 and 20 personnel. NATO and U.S. doctrine define a section as an organization "larger than a squad, but smaller than a platoon." As such, two or more sections usually make up an army platoon or an air force flight. Land forces NATO Standard NATO symbol for a ''section'' consists of two dots (●●) placed above a framed unit icon. Australian Army At the start of World War I, the Australian Army used a section that consisted of 27 men including the section commander, a sergeant. During World War II, a rifle section comprised ten soldiers with a corporal in command and a lance-corporal as his second-in-command. The corporal used an M1928 Thompson submachine gun, while one of the privates used a Bren gun. The other eight soldiers all used No.1 Mk.3 Lee–Enfield rifles with a bayonet and scabbard. They all carried two or three No.36 Mills bomb grenades. After World War II, and during the Vietn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Squad
In military terminology, a squad is among the smallest of Military organization, military organizations and is led by a non-commissioned officer. NATO and United States, U.S. doctrine define a squad as an organization "larger than a fireteam, team, but smaller than a Section (military unit), section", while United States Army, U.S. Army doctrine further defines a squad as a "small military unit typically containing two or more Fireteam#United_States, fire teams". In American usage, a squad consists of eight to fourteen soldiers, and may be further subdivided into fireteams. Organization NATO The standard NATO symbol for a ''squad'' consists of one single dot (●) placed above a framed unit icon. United States United States Army Historically, a "squad" in the US Army was a sub-unit of a Section (military unit)#United States Armed Forces, section, consisting of from as few as two soldiers to as many as 9–10 soldiers and was originally used primarily for drill and adminis ...

Infantry
Infantry, or infantryman are a type of soldier who specialize in ground combat, typically fighting dismounted. Historically the term was used to describe foot soldiers, i.e. those who march and fight on foot. In modern usage, the term broadly encompasses a wide variety of subspecialties, including light infantry, irregular infantry, heavy infantry, mountain infantry, motorized infantry, mechanized infantry, Airborne forces, airborne infantry, Air assault, air assault infantry, and Marines, naval infantry. Other subtypes of infantry, such as line infantry and mounted infantry, were once commonplace but fell out of favor in the 1800s with the invention of more accurate and powerful weapons. Etymology and terminology In English, use of the term ''infantry'' began about the 1570s, describing soldiers who march and fight on foot. The word derives from Middle French , from older Italian (also Spanish) ''infanteria'' (foot soldiers too inexperienced for cavalry), from Latin '' ...

Air Assault
Air assault is the movement of ground-based military forces by vertical take-off and landing (VTOL) aircraft, such as helicopters, to seize and hold key terrain that has not been fully secured, and to directly engage enemy forces behind enemy lines.Russ & Susan Bryant P.63 In addition to regular infantry training, air-assault units usually receive training in rappelling, fast-roping techniques, and airborne forces, air transportation. Their equipment is sometimes designed or field-modified to allow better transportation and/or carrying within aircraft. The United States Army field manual FM 1-02 (FM 101-5-1) describes an "air assault operation" as an operation in which assault forces (combat, combat support, and combat service support), using the firepower, mobility, and total integration of helicopter assets, maneuver on the battlefield under the control of the ground or air maneuver commander to engage and destroy enemy forces or to seize and hold key terrain usually behind en ...

Fast-roping
Fast-roping is a technique for descending a thick rope, allowing troops to deploy from a helicopter in places where the aircraft cannot touch down. The person holds onto the rope with gloved hands (with or without using their feet) and slides down it. Several people can slide down the same rope simultaneously, provided that there is a gap of about between them, so that each one has time to get out of the way when they reach the ground. Fast roping is quicker than abseiling, abseiling (rappelling), although more dangerous, particularly if the person is carrying a heavy load, because the rope is not attached to them with a Climbing equipment#Descenders, descender. The technique is particularly useful for Marines, naval infantry, who can use it to board ships at sea. History The technique was first developed by the UK with British rope manufacturer Marlow Ropes, and first used in combat during the Falklands War. The original rope was made of thick nylon that could be used in a m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Abseiling
Abseiling ( ; ), also known as rappelling ( ; ), is the controlled descent of a steep slope, such as a rock face, by moving down a rope. When abseiling, the person descending controls their own movement down a static or fixed rope, in contrast to Belaying, lowering off, in which the rope attached to the person descending is paid out by their belayer. Description The technique is used by Climbing, climbers, mountaineers, Caving, cavers, Canyoning, canyoners, search and rescue and rope access technicians to descend cliffs or slopes when they are too steep or dangerous to descend without protection. Many climbers use this technique to protect established Anchor (climbing), anchors from damage. Rope access technicians also use this as a method to access difficult-to-reach areas from above for various industrial applications like maintenance, construction, inspection and welding. To descend safely, abseilers use a variety of techniques to increase the friction on the rope to t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Helicopter
A helicopter is a type of rotorcraft in which Lift (force), lift and thrust are supplied by horizontally spinning Helicopter rotor, rotors. This allows the helicopter to VTOL, take off and land vertically, to hover (helicopter), hover, and to fly forward, backward and laterally. These attributes allow helicopters to be used in congested or isolated areas where fixed-wing aircraft and many forms of short take-off and landing (STOL) or short take-off and vertical landing (STOVL) aircraft cannot perform without a runway. The Focke-Wulf Fw 61 was the first successful, practical, and fully controllable helicopter in 1936, while in 1942, the Sikorsky R-4 became the first helicopter to reach full-scale mass production, production. Starting in 1939 and through 1943, Igor Sikorsky worked on the development of the Vought-Sikorsky VS-300, VS-300, which over four iterations, became the basis for modern helicopters with a single main rotor and a single tail rotor.

LHA (hull Classification Symbol)
underway in June 1997 Landing helicopter assault (LHA) is the United States Navy's hull classification symbol for the general-purpose helicopter-carrying amphibious assault ships of the ''Tarawa'' and ''America'' classes. Their purpose is to project power and maintain presence by serving as the cornerstone of the amphibious ready group or expeditionary strike group. They are used to transport Fleet Marine Force personnel and equipment while operating in a deployed marine expeditionary unit (MEU) or marine expeditionary brigade (MEB). They normally travel in task forces called " amphibious ready groups". These ships and their escorts are capable of anything from military landing operations to humanitarian operations. These vessels are built with a full flight deck similar in appearance to an aircraft carrier to operate utility and attack helicopters. They can also operate tilt rotor aircraft such as the MV-22 Osprey and STOVL aircraft such as the AV-8 Harrier and the F-3 ...
