Learn about our Editorial Process Updated on 02/23/21 In the Marine Corps, jobs or Marine Occupational Specialties (MOS) are divided into career fields. For those who work with aviation (helicopters, planes, other), the career field designations are OccFlds 60/61/62 as you will see below. The aviation MOS is the 6000 field. The first two numbers designate the three primary position such as mechanic (60), helicopters (61), and fixed wing aircraft (62). About Occupational Fields The aircraft maintenance occupational fields include direct and indirect support of the total air frames and power plant package of all aviation aircraft weapons systems. While there is similarity in the skills required to provide this support, the systems being supported are diverse. The following examples are provided: direct support-repair and servicing at the organizational maintenance activity which is normally accomplished on aircraft, such as pre-flight and servicing of aircraft and their systems; indirect support-repair of components at the intermediate maintenance activity which is normally accomplished off aircraft, such as hydraulic actuators, servos, and accumulators, aircraft engines, and transmissions. Marines entering these fields receive MOS 6000, Basic Aircraft Maintenance Marine, and then progress through specific hard skill MOSs. After completion of formal training, Marines are qualified to maintain air frames and aircraft components. As the Marine progresses, repair and administrative requirements for multiple systems take on an equal importance until the Marine is placed in a management/supervisory position. Billets for both repair and administration are varied and extend from the squadron level to staff positions at the wing, force commander, and Headquarters U.S. Marine Corps level.
