High-altitude military parachuting is a style of parachuting in which personnel, equipment, or supplies are airdropped from an aircraft flying at a high altitude. The technique is often used in covert operations.
High-altitude military parachuting is generally categorised as either High-altitude high-opening (HAHO) or High-altitude low-opening (HALO), depending upon the altitude at which parachutes are deployed after exiting the aircraft. In the HALO technique, the parachutist opens the parachute at a low altitude after free-falling for a period of time, while in the HAHO technique, the parachutist opens the parachute at a high altitude just a few seconds after jumping from the aircraft.
