How high does the military airborne jump from?

Answer 1

Typically in the United States tandem skydiving is done from 10,000' up to 14,000, with a few DZs offering exit altitudes of up to 18,000. In order to go above 14,000' MSL legally, all crew and passengers are required to be on supplemental oxygen. So, exit altitude above 14,000 above sea level you'll have an oxygen mask in the airplane, if not you're in violation of the Federal Aviation Regulations. The United States Parachute Association (USPA) indicates a minimum tandem exit altitude of 7,000' above ground level.

Answer 2

The standard jump mission is done at a relatively low height of 1,200 feet. This minimizes time in the air and reduces the area of dispersion. However, for High Altitude jumps, the HALO/HAHO insertions, the troops jump from altitudes between 15,000 feet (4,600 m) and 35,000 feet (11,000 m).
