Marine Corps Parachute Riggers (MOS 0451)– also known as Airborne and Air Delivery Specialists – receive a wide variety of skilled training to perform airborne (parachute drop) operations of personnel, equipment/gear, as well as equipment recovery operations using various slings and equipment securing gear.

Type of MOS: PMOS

Rank Range: MGySgt to Pvt

Job Description: Airborne and air delivery specialists are responsible for the maintenance of all life safety equipment relating to Airborne/Airdrop operations. In addition, they will assist in preparing the supplies and equipment necessary to deliver personnel and equipment via parachute and conduct subsequent equipment recovery and throughput operations.

They are responsible for performing parachute repack as well as conducting preventive and corrective maintenance on all airdrop equipment and will assist in evaluating proposed Landing Zone/Drop Zones in order to support the planning and execution of effective personnel, supplies, and equipment clearance during airborne, airdrop and equipment recovery operations. They will also perform various supervisory duties in support of airborne and airdrop missions to include, but not limited to, mission planning, Jumpmaster (military freefall and static line), Drop Zone Safety and Malfunctions Officers.

Job Requirements:

(1) Must be a U.S. citizen.

(2) Must be a volunteer.

(3) Must be eligible for a secret security clearance.

(4) Must possess a GT score of 100 or higher.

(5) Must pass the U.S. Army Physical Fitness Test and have current CWS2 swim qualification.

NOTE: This is a different test than the Marine Corps PFT.  The USMC PFT requires Marines to do pullups, crunches, and a 3-mile run.  The Army PFT requires the Marines while in Army schools to pass the following exercises:  Pushups 2 minutes and Sit-ups 2 minutes, and a 2-mile run.  Marines usually do not have an issue with PT tests, but if you are not used to doing timed pushups, you need to practice the two-minute test on pushups.

  Also, crunches and sit-ups are different.  Crunches are basically half sit-ups with the hands crossed over the chest and elbows touching the thighs, while the sit-up is a full sit-up with hands locked behind the head touching the elbows to the knees.  The shorter run is only an issue for Marines who tend to pace their three-mile run at a slower pace and could run the two-mile faster with some practice.  But there have been Marines to fail the course at the beginning by failing pushups.  Do not assume you can do two minutes worth of pushups without practicing pushups for two-minute sets.

About the CWS2 Swimming Qualification
