Helocast
Helocasting is an airborne technique used by small unit, special operations forces, also practiced extensively by the US Army's light infantry units, to insert into a military area of operations. The small unit is flown, by helicopter, to a maritime insertion point. Once there, the aircraft assumes an altitude just above the water's surface and an airspeed of or less. Team members then exit the aircraft and enter the water. In some cases, depending upon the mission parameters and the aircraft used, personnel may be inserted along with an inflatable boat An inflatable boat is a lightweight boat constructed with its sides and bow made of flexible tubes containing pressurised gas. For smaller boats, the floor and hull is often flexible, while for boats longer than , the floor typically consist ... for over-the-horizon operations. When a fully inflated boat is transported and inserted with personnel, this type of operation is known as a "hard duck". In cases where a fully in ...

Special Operations Forces
Special forces and special operations forces (SOF) are military units trained to conduct special operations. NATO has defined special operations as "military activities conducted by specially designated, organized, selected, trained and equipped forces using unconventional techniques and modes of employment". Special forces emerged in the early 20th century, with a significant growth in the field during the Second World War, when "every major army involved in the fighting" created formations devoted to special operations behind enemy lines. Depending on the country, special forces may perform functions including Airborne forces, airborne operations, counter-insurgency, counter-terrorism, foreign internal defense, Covert operations, covert ops, Direct action (military), direct action, Hostage crises, hostage rescue, high-value targets/Manhunt (military), manhunt, intelligence, surveillance, target acquisition, and reconnaissance, intelligence operations, Mobility (military), mo ...

Area Of Operations
In U.S. armed forces parlance, an area of operations (AO) is an operational area defined by the force commander for land, air, and naval forces conduct of combat and non-combat activities. Areas of operations do not typically encompass the entire operational area of the force commander, but should be large enough for subordinate commanders to accomplish their goals, achieve objectives and missions, and to protect their forces. Within an AO there will typically be one main supply route A main supply route (MSR) is the route or routes designated within an area of operations upon which the bulk of traffic flows in support of military operations and humanitarian operations. MSR is a term that is also used in insurgency and irregul ... along which vehicles, personnel and supplies will be transported.Joint Publication 3-0 page IV-13 See also * Area of responsibility References Military terminology of the United States {{mil-stub ...

Helicopter
A helicopter is a type of rotorcraft in which lift and thrust are supplied by horizontally spinning rotors. This allows the helicopter to take off and land vertically, to 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 STOL (Short TakeOff and Landing) or STOVL (Short TakeOff and Vertical Landing) aircraft cannot perform without a runway. In 1942, the Sikorsky R-4 became the first helicopter to reach full-scale production.Munson 1968.Hirschberg, Michael J. and David K. Dailey"Sikorsky". ''US and Russian Helicopter Development in the 20th Century'', American Helicopter Society, International. 7 July 2000. Although most earlier designs used more than one main rotor, the configuration of a single main rotor accompanied by a vertical anti-torque tail rotor (i.e. unicopter, not to be confused with the single-blade monocopter) has become the most comm ...

Inflatable Boat
An inflatable boat is a lightweight boat constructed with its sides and bow made of flexible tubes containing pressurised gas. For smaller boats, the floor and hull is often flexible, while for boats longer than , the floor typically consists of three to five rigid plywood or aluminium sheets fixed between the tubes, but not joined rigidly together. Often the transom is rigid, providing a location and structure for mounting an outboard motor. Some inflatable boats can be disassembled and packed into a small volume, so that they can be easily stored and transported. The boat, when inflated, is kept rigid cross-ways by a foldable removable thwart. This feature makes these boats suitable for liferafts for larger boats or aircraft, and for travel or recreational purposes. History Early attempts There are ancient carved images of animal skins filled with air being used as one-man floats to cross rivers. These floats were inflated by mouth.
