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.

Communications Military Occupation Specialties (MOS)

Below are other Marine Corps Enlisted Military Occupation Specialties which are organized under this occupational field:

0612 - Tactical Switching Operator - Typical duties of this MOS is to install, operate, and maintain analog, TDM, and internet telecommunications that are reliable to transmit classified and unclassified voice, video, and data.

0613 - Construction Wireman - This MOS operates specialized construction equipment to install underground / above ground cabling systems in buildings and maintaining aerial cable distribution systems.

0619 - Telecommunications Systems Chief - This MOS is in charge of managing budget, inventory, plans, quality control, and inside and outside plant telecommunications networks. 

0621 - Field Radio Operator - This MOS set up and tune of radio equipment including antennas and power sources. In order to make establishing contact with distant stations, changing to frequencies and cryptographic codes and maintaining equipment are required by the radio operator. 

0622 - Digital (Multi-channel) Wideband Transmission Equipment Operator - This MOS specifically focuses on installing, operating and maintaining the AN/MRC-142 Digital Wideband Transmission Systems (DWTS) which is essential to effective internet communications. 

0623 - Tropospheric Scatter Radio Multi-channel Equipment Operator - This MOS is a Marine that installs, operates and maintains the AN/TRC-170 (Tropospheric Scatter Microwave Radio Terminal). This enable wireless communications between stations over 100 miles apart.

0627 SHF Satellite Communications Operator-Maintainer - This MOS is a Marine that installs, operates and maintains various satellite communication platforms to handle classified and unclassified data in both Marine bases and when deployed.  

0629 - Radio Chief - This Marine is a Staff Sergeant and above and is responsible for preparing and executing radio communications. The Radio Chiefs has additional responsibilities and must understand maintenance and be familiar with budgeting, and administration of reliable radio operations. 

0648 - Spectrum Manager - This Marine is a Staff Sergeant and above and must be an expert of all DOD/Service and commercial S-D equipment and systems. 

0651 Cyber Network Operator - This MOS installs, configures and manages cyber network systems including Microsoft based curriculum and MS Exchange/Server, CISCO Certified Network Associate (CCNA) modules 1, 2 and 3, as well as other authorized cyber network systems.

0659 - Cyber Network Systems Chiefs - This MOS installs, operates, integrates and troubleshoots in order to maintain optimum secure cyber communication systems. 

0681 - Information Security Technician - The Marine in this MOS serves as the primary functional proponent for cryptographic key management infrastructure making communications secure. 

0688 - Cyber Security Apprentice - The Marine in this MOS secure the internet communications systems. They execute security policies, implement Cyber network security measures and network intrusion detections. They also assist with forensics and assist with security incident handling along the network.

0689 - Cyber Security Technician - This MOS is responsible for ensuring Marine Corps information systems data availability, integrity authentication, confidentiality, and non-repudiation.

0699 - Communications Chief - Communications Chiefs are the Senior Staff Noncommissioned Officers that directly assist the communications officer in developing the communications plan. This senior MOS is responsible for the supervision of the installation, operation and maintenance of communication facilities. Additionally, they must have overall knowledge of maintenance, budgeting and administration fo the above field of MOS's.
