Marine occupational field code 5900 is the classification for electronics maintenance. Marine Corps jobs within this field code can involve maintenance, repair, and operation of a variety of different types of electronic equipment, mainly within the Marine Air Command and Control Systems (MACCS) network. Electronic equipment supporting MACCS serves the areas of: air defense, air defense weaponry, surveillance radar, radio communications, air traffic control, and data monitoring. Personnel working in occupational field codes beginning with 59 will need to have skills and competency to perform the necessary maintenance, repair, and operational tasks pertaining to MACCS equipment as well as other sophisticated electronics which may include: computer hardware, communication systems, data signals, data monitoring, and radar.

Marines entering the electronic maintenance occupational field will receive formal courses of instruction in basic electronics followed by detailed instruction involving specific electronic, data, communication, and radar systems. After completion of formal training, a military occupational specialty (MOS) will be assigned which designates a specific job in the electronics maintenance field, usually working within the Marine Air Command and Control Systems network.

Military service, in general, offers a multitude of apprenticeship opportunities. The United Services Military Apprenticeship Program (USMAP) works in conjunction with the U.S. Department of Labor (DOL) to offer apprenticeships for Coast Guard, Marine Corps, and Navy service members. Department of Labor Certificates of Apprenticeship Completion are awarded through the collaboration of the USMAP and DOL. There are a multitude of apprenticeship offerings in the electronics maintenance field specifically for MOSs within marine occupational field code 5900. Skills and certifications obtained through military and marine apprenticeships can be highly beneficial for rising within the Marine electronic maintenance ranks. Apprenticeship certificates are also applicable for utilization in civilian occupations upon leaving military service.
