Fast Rope
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 (rappelling), although more dangerous, particularly if the person is carrying a heavy load, because the rope is not attached to them with a descender. The technique is particularly useful for 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 manner akin to a fireman's pole. The special ropes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

MD Helicopters MH-6 Little Bird
The Boeing MH-6M Little Bird (nicknamed the Killer Egg) and its attack variant, the AH-6, are light helicopters used for special operations in the United States Army. Originally based on a modified OH-6A, it was later based on the MD 500E, with a single five-bladed main rotor. The newest version, the MH-6M, is based on the MD 530F and has a single, six-bladed main rotor and four-bladed tail rotor. Development The OH-6 was started in 1960, when the U.S. Army issued Technical Specification 153 for a Light Observation Helicopter (LOH) that could perform personnel transport, escort and attack missions, casualty evacuation, and observation. Twelve companies took part in the competition and Hughes Tool Company's Aircraft Division submitted the Model 369. Two designs, those submitted by Fairchild-Hiller and Bell, were selected as finalists by the Army-Navy design competition board, but the Army later included the helicopter from Hughes as well. The first Model 369 prototype fle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Glove
A glove is a garment covering the hand. Gloves usually have separate sheaths or openings for each finger and the thumb. If there is an opening but no (or a short) covering sheath for each finger they are called fingerless gloves. Fingerless gloves having one small opening rather than individual openings for each finger are sometimes called gauntlets, though gauntlets are not necessarily fingerless. Gloves which cover the entire hand or fist but do not have separate finger openings or sheaths are called mittens. Mittens are warmer than other styles of gloves made of the same material because fingers maintain their warmth better when they are in contact with each other; reduced surface area reduces heat loss. A hybrid of glove and mitten contains open-ended sheaths for the four fingers (as in a fingerless glove, but not the thumb) and an additional compartment encapsulating the four fingers. This compartment can be lifted off the fingers and folded back to allow the individual fi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Atlas Oryx
The Atlas Oryx (named after the Oryx antelope) is a medium-sized utility helicopter ostensibly developed and manufactured by the Atlas Aircraft Corporation (now Denel Aeronautics) of South Africa. Its largest operator is the South African Air Force (SAAF), having been originally developed to fulfil their needs. Development of the Oryx commenced during the early 1980s, largely in response to the wartime demands of the Border War and the imposition of an arms embargo upon South Africa, which prevented the importing of foreign transport helicopters such as the Aérospatiale SA 330 Puma. Seeking to improve and augment the SAAF's existing fleet of rotorcraft, domestic industries examined means of improving the Puma helicopter. The Oryx is closely connected to the Denel Rooivalk attack helicopter, both rotorcraft being based on the Puma and development having been worked on in parallel around roughly the same time period. Following the conversion of a single Puma to the Oryx configur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Close Quarters Combat
Close-quarters combat (CQC) or close-quarters battle (CQB) is a tactical situation that involves a physical fight with firearms involved between multiple combatants at short range. It can occur between military units, police/corrections officers and criminal elements, and in other similar situations. In warfare, it usually consists of units or teams of varying size engaging the target or attacking personnel with personal weapons within a distance of up to 100 meters (110 yards), from proximity hand-to-hand combat to close-quarter target negotiation with usually automatic weapons. In the typical close combat scenario, the attackers try a very fast, violent takeover of a vehicle or structure controlled by the defenders, who usually have no easy method to withdraw. Because attacking and defending personnel, hostages/civilians, and friendly personnel can be closely intermingled, close-quarters combat demands a rapid assault and a precise implementation of lethal force. The operators ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rope
A rope is a group of yarns, plies, fibres, or strands that are twisted or braided together into a larger and stronger form. Ropes have tensile strength and so can be used for dragging and lifting. Rope is thicker and stronger than similarly constructed cord, string, and twine. Construction Rope may be constructed of any long, stringy, fibrous material, but generally is constructed of certain natural or synthetic fibres. Synthetic fibre ropes are significantly stronger than their natural fibre counterparts, they have a higher tensile strength, they are more resistant to rotting than ropes created from natural fibres, and they can be made to float on water. But synthetic ropes also possess certain disadvantages, including slipperiness, and some can be damaged more easily by UV light. Common natural fibres for rope are Manila hemp, hemp, linen, cotton, coir, jute, straw, and sisal. Synthetic fibres in use for rope-making include polypropylene, nylon, polyesters (e.g. ...

United States Army
The United States Army (USA) is the land service branch of the United States Armed Forces. It is one of the eight U.S. uniformed services, and is designated as the Army of the United States in the U.S. Constitution.Article II, section 2, clause 1 of the United States Constitution (1789). See alsTitle 10, Subtitle B, Chapter 301, Section 3001 The oldest and most senior branch of the U.S. military in order of precedence, the modern U.S. Army has its roots in the Continental Army, which was formed 14 June 1775 to fight the American Revolutionary War (1775–1783)—before the United States was established as a country. After the Revolutionary War, the Congress of the Confederation created the United States Army on 3 June 1784 to replace the disbanded Continental Army.Library of CongressJournals of the Continental Congress, Volume 27/ref> The United States Army considers itself to be a continuation of the Continental Army, and thus considers its institutional inception to be th ...

Fireman's Pole
A fireman's pole (also called a firefighter's pole, sliding pole or fire pole) is a pole that firefighters slide down to quickly reach the ground floor of a fire station. This allows them to respond to an emergency call faster, as they arrive at the fire engine faster than by using a standard staircase. In the 1870s, answering an alarm, Chicago fireman George Reid decided to use the long-pole the company employed to lift horse's hay from the upper-loft to slide to the ground floor, arriving well ahead of the rest of the company. Company Captain David Kenyon of Engine Company 21 then successfully petitioned the department be allowed to install a pole through the floor of the loft sleeping space to create what became the standard set-up. Overview The firefighter's pole is found in multi-level fire stations, if the firefighters' living quarters are located upstairs. When they are dispatched to an emergency, the firefighters descend to the ground floor, put on their firefighti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
