Within the Marine Corps, there are many different Military Occupational Specialties (MOSs). These are the individual jobs that each Marine performs as part of the larger military infrastructure. Every Marine is a rifleman, but for enlisted Marines, there are a wide variety of careers and specialties from which to choose. 

Basics of USMC Communications MOS

Marines in the Communications field are integral to all elements of this branch of the U.S. military.

Consider how important it is to relay accurate information in a timely way when in a combat situation. But there's more to this field than radio communications.

Marines in this field are responsible for the  design, installation, connection and operation of communication networks and information systems used to transmit information and data throughout the entire Marine Air-Ground Task Force. Communications Marines are part of every ground force mission, as specialists, and keep the critical flow of information moving. 

Marines in this field also operate and perform preventive maintenance on both hardware and software systems including telephone, teletype, switching, radio, cryptography and computer systems. 

The training for communications jobs in the Marines includes basic training, then combat training. After that, Marines in this field go to Communications Systems Training at the Marine Air Ground Task Force Training Command in Twentynine Palms, California.

Keys to Success in Marine Communications

In order to be successful in this field, Communications Marines need basic to advanced language skills and must be able to master precise communication and computer procedures, as well as interact on a daily basis with users to solve communication systems challenges.


Attention to detail and the ability to work closely with others are essential requirements. Eligibility for a security clearance is a requirement for some communication systems specialties, due to the sensitive nature of much of the information they'll be handling. Marines entering Communications Systems are assigned the designation of MOS 0600, Basic Communications Systems Marine.

Entry-level jobs for Marines in the communications field include work as a field radio operator, wireman, multichannel equipment operator, satellite communications equipment operator, information systems specialist, data network systems specialist, and information assurance and information security technicians.

The opportunity to participate in a formal apprenticeship program leading to receipt of a Department of Labor Certificate of Apprenticeship Completion may be available.
