Note. The first commander (0-5) in the chain of command can extend or waive the individual jumper's requirement for executing a parachute jump from 60 days up to 90 days after successful completion of Basic Airborne Refresher Training. Unit commanders take into consideration each individual's experience level with the T-11 and MC-6, and their ability to retain the crucial information they receive during Basic Airborne Refresher Training. The 90 day waiver is submitted on a memorandum for record and placed with the individual's jump log.
