HAHO - High Altitude High Open. One of the two types of high altitude parachute jumps, in this one the soldiers jump at an altitude of 30,000 feet or more and their parachute opens just a few seconds after jumping. This is a common technique for inserting special forces into areas that an aircraft cannot fly directly over, like in this instance, with the parachute being opened immediately this allows for a longer hang time and traveling distance of up to 40 miles.
HALO - High Altitude Low Open. The other type of high altitude military parachute jump, in this technique the parachutist jumps at 30,000 and free-falls at terminal velocity and open their chute until they are at a very low altitude, usually around 3,000 feet. This is by far the most dangerous type of parachute insertion, because of the high altitude the parachutist has to wear oxygen tanks and the sudden deceleration of opening the parachute can cause the head to snap back into the tanks, opening the chute too late can also prove fatal and when dropping into water a person can get tangled in their chute and drown. The HALO allows an aircraft to fly above surface-to-air missile range and deploy equipment, supplies and personnel, not opening parachutes right away has the advantage of avoiding detection by radar and minimizes exposure to antiaircraft fire.
