BLS OOH median $96,800
Fiber Optic or Network Infrastructure Technician
$55k – $115k
The official 5974 entry specifically includes fiber optic cables and switched LAN devices. That can translate into network infrastructure roles supporting installation, testing, documentation, and repair of physical and logical network paths. This is a strong near-term path for Marines who enjoy hands-on work more than pure administration. Add cable testing, labeling, diagrams, equipment rooms, switches, and safety practices where accurate.

Virtualization or Server Support Technician
$70k – $135k
Virtual systems and servers give a 5974 a credible bridge into infrastructure support when the resume names the environment and tasks clearly. Employers look for provisioning, troubleshooting, backup awareness, firmware or software updates, incident response, documentation, and escalation habits. If your experience was limited, pair it with labs or vendor training and keep claims accurate.

Defense Cyber Workforce Technician Pathway
$75k – $145k
NAVMC notes that 5974 billets may be coded to DoD Cyber Workforce Framework work roles. That can be valuable for cleared IT, systems support, and cyber workforce contractor roles. Do not assume every billet qualifies the same way. Document the work role if known, the training completed, security requirements, systems supported, and the actual tasks performed.

Transferable Strengths: What Civilian Employers Actually See
◆
C2 systems context
5974 work sits inside aviation command and control, not generic office IT. Explain how systems supported operational users, data flow, and mission coordination so employers see the stakes behind the technical tasks.
◆
Hybrid hardware and software troubleshooting
Fiber, switches, computers, servers, virtual systems, and firmware create a broad troubleshooting base. Translate that into layered diagnosis across physical, network, system, and application-adjacent issues.
◆
Maintenance-shop discipline
Repair evacuation, parts requisition, maintenance reports, and shop supervision show operational maturity. Civilian IT teams value people who can document, prioritize, coordinate, and close the loop.
◆
Cyber workforce alignment potential
If your billet had a DCWF role code, that is worth documenting. It can support cleared IT and cyber workforce roles when paired with the actual tasks, training, and security requirements.
◆
Technical planning support
Providing expertise for planning, employment, and installation of aviation C2 systems shows you can work before the outage happens. That is valuable in projects, upgrades, and site activations.
Section 03
Common Mistakes 5974s Make in the Civilian Job Search
01
Applying only to generic help desk jobs
Help desk can be a bridge, but 5974 has stronger systems, network, infrastructure, and defense C2 value. Search for systems technician, network technician, C2 systems, virtualization support, and cleared IT roles.
02
Claiming cyber without work-role proof
The MOS may connect to DCWF work roles, but not every experience is the same. Be precise about billet coding, training, tasks, systems, and credentials rather than using cyber as a blanket label.
03
Forgetting physical infrastructure
Fiber, switches, cabling, and site equipment matter. Many 5974s undersell the hands-on infrastructure side by writing only about computers and servers.
Section 04
Certifications That Can Improve the Signal
CompTIA Security+
Cost Exam voucher pricing changes by market; verify current CompTIA store priceTime Usually weeks to a few months of studyFormat Vendor-neutral cybersecurity exam
Security+ is a common baseline for cleared IT and DoD contractor systems roles. For 5974s, it pairs well with DCWF-aligned billets, C2 systems support, and secure networked maintenance environments.
Cleared IT signal · Often requested in defense systems postings
CompTIA Network+
Cost Exam voucher pricing changes by market; verify current CompTIA store priceTime Usually weeks to a few months of studyFormat Vendor-neutral networking exam
Network+ helps translate switched LAN, fiber, server, and troubleshooting experience into civilian network language. It is especially useful for 5974s moving toward network technician or systems administrator roles.
Foundation credential · Strong match for LAN and infrastructure work
Cisco CCNA
Cost Cisco exam pricing varies by country and exam delivery partnerTime Usually several months of studyFormat Proctored networking exam
CCNA is a stronger networking signal for Marines targeting network administration, C2 systems, and infrastructure roles. It should be backed by hands-on switch, routing, cabling, documentation, or lab experience.
Higher ceiling · Helps pursue network admin and C2 infrastructure roles

Resume Translation: From Military data systems maintenance to Civilian Language
The 5974 resume has to translate systems, maintenance discipline, troubleshooting, records, safety, and mission impact without assuming a civilian recruiter understands Marine aviation terminology.
Before: Vague military language that undersells your scope
Served as a 5974 Marine. Maintained equipment, troubleshot systems, supported missions, trained Marines, managed records, and coordinated repairs in an aviation unit.
↓
After: Civilian language that gets callbacks
Installed, configured, troubleshot, repaired, and maintained communications data systems supporting Marine aviation command-and-control operations. Supported fiber optic cabling, switched LAN devices, end-user computers, servers, virtual systems, software, and firmware while documenting outages, corrective actions, and maintenance status. Coordinated repair evacuation, parts requisition, maintenance reports, and technical support across maintenance activities to sustain operational availability. Provided technical input for planning, employment, installation, and upgrade of aviation command-and-control systems in environments requiring disciplined security, configuration control, and accurate records.
Use this structure for each bullet
System or equipment supported, with operating environment
Failure, inspection, configuration, or readiness problem addressed
Diagnostic method, maintenance action, or coordination step used
Compliance, safety, cyber, supply, or documentation requirement managed
Result in uptime, inspection readiness, sortie support, repair cycle time, or team output
Always quantify: systems supported, tickets or outages closed, devices configured, fiber runs tested, servers maintained, reports completed
