Static line military parachuting is a basic military skill for all airborne forces which is designed to drop a body of men behind enemy lines for operations. Military freefalling is a very dangerous activity that requires a high degree of skill. Unlike civilian freefallers who jump by day and clean, a SEAL may jump with over 200 pounds of equipment on top of their own bodyweight at night and be prepared to deal with the enemy on the ground below him.

There are a variety of insertion techniques that can be used including HALO (High Altitude Low Opening) and HAHO (High Altitude High Opening). HALO is military freefalling from altitudes in excess of 25,000 feet while HAHO is where the parachute canopy is deployed shortly after exiting the aircraft and this allows a SEAL to travel up to 25 miles from the aircraft exit position onto a target with no warning.
