5974 system administrator

The Marine Corps uses a four-digit Military Occupational Specialty (MOS) code to identify jobs. The MOS code 5974 is for Tactical Data Systems Administrators (TDSA). TDSAs plan and manage the Marine Air Command and Control Systems (MACCS) Tactical Data Systems. They also maintain the hardware and software suites.

TDSAs perform tasks such as: Repairing electrical aircraft components and support equipment Tracking and inventorying support equipment Training subordinates

The first two digits of the MOS code identify the occupational field, and the last two digits identify the specific job in that field.
