U.S. Army Air Assault School is a 10-day course

U.S. Army Air Assault School is a 10-day course designed to prepare Soldiers for insertion, evacuation, and pathfinder missions that call for the use of multipurpose transportation and assault helicopters. Air Assault training focuses on the mastery of rappelling techniques and sling load procedures, skills that involve intense concentration and a commitment to safety and preparation.

Most Air Assault cadets will attend Sabalauski Air Assault School, located at Fort Campbell, Ky. Training is broken into three phases, each lasting three days: Combat Assault Phase, Sling Load Phase, and Rappel Phase. On graduation day, cadets will undergo a 12-mile rucksack march. When they complete the march, they will earn their wings as official Air Assault Soldiers.

Air Assault School is necessarily physically and mentally demanding, as Soldiers will be required to handle heavy equipment and perform dangerous tasks under extremely stressful conditions. Successful candidates must possess a keen eye for detail and a dedication to meticulous preparation.
