7315 vs ENG
Unmanned Aircraft System (UAS) Officer (USMC) vs Naval Engineering Specialty (USCG)
One storms beaches. The other patrols them afterward. Context and timing matter.
The 7315 experience, condensed: your job is to lead an emerging capability that ground commanders are still learning how to use effectively — which means half your job is education and advocacy, not just operations. The ENG experience, condensed: when something breaks at sea (and it will, constantly), your engineering team fixes it while the ship continues its mission because 'return to port for repairs' is a phrase that makes commanding officers physically ill. When both hit the job market: the 7315 discovers that the community is also figuring out its own career path — how UAS billets feed into senior leadership, whether 7315 is a terminal assignment or a stepping stone, and how to develop officers who understand both aviation and ground force requirements. The ENG finds that your management experience and technical breadth translate directly to plant engineering, facilities management, and maritime engineering positions in the civilian sector paying $100-140K. Same DD-214, wildly different job fairs.

The pitch versus what people who actually did the job report back.
“Marine Corps UAS Officers command and direct unmanned aerial system operations across the MAGTF. You plan and execute ISR missions using the RQ-21A Blackjack and other platforms, integrate UAS into ground and aviation operations, and manage UAS detachments that support battalion and regimental commanders. The Marine UAS community is one of the fastest-growing warfighting functions in the Corps — every major ground operation now expects persistent ISR overhead, and UAS provides it at a fraction of the cost of manned aviation. As a 7315, you sit at the intersection of aviation planning, intelligence operations, and ground force support. You will brief commanders, coordinate airspace with controlling agencies, and build the collection plan that determines what commanders know and when they know it. The community is small, influential, and expanding.”
UAS Officer is a community in transition, and 'transition' in Marine Corps terms means doctrine, equipment, and organizational structure are all moving simultaneously. The RQ-21A Blackjack replaced the RQ-7B Shadow and is itself being evaluated against emerging platforms. Your job is to lead an emerging capability that ground commanders are still learning how to use effectively — which means half your job is education and advocacy, not just operations. Airspace coordination is a constant friction point: small UAS operate in the same airspace as manned aviation, and deconfliction requires persistent coordination with air traffic control and the aviation combat element. The community is also figuring out its own career path — how UAS billets feed into senior leadership, whether 7315 is a terminal assignment or a stepping stone, and how to develop officers who understand both aviation and ground force requirements. Get in early, shape the doctrine, and accept that the playbook is still being written.
“As a Marine Safety Engineer, you'll ensure the safety and structural integrity of vessels operating in U.S. waters. You'll conduct inspections, review engineering plans, and apply your technical expertise to prevent maritime disasters — building a career at the intersection of engineering, law, and public safety.”
You're an officer who is responsible for every mechanical and electrical system on a Coast Guard cutter — main engines, generators, HVAC, freshwater systems, hydraulics, and whatever else the previous ENG left in various states of repair. When something breaks at sea (and it will, constantly), your engineering team fixes it while the ship continues its mission because 'return to port for repairs' is a phrase that makes commanding officers physically ill. You manage a department of engineers, electricians, and damage controlmen who keep a floating city operational in an environment that exists to corrode, short-circuit, and break everything. Your planned maintenance system generates work orders faster than your team can complete them, and the backlog is a living document that gives you anxiety. Casualty control drills — simulating flooding, fires, and loss of propulsion — happen constantly because the ocean doesn't give warnings. The engineering plant on a National Security Cutter is a modern marvel; the engineering plant on a 40-year-old medium endurance cutter is a testament to your team's ability to keep things alive through stubbornness and creative maintenance. Your management experience and technical breadth translate directly to plant engineering, facilities management, and maritime engineering positions in the civilian sector paying $100-140K. The commercial shipping industry specifically values Coast Guard engineering officers.
The Real Life
Same dimensions, side by side. 7315 on the left, ENG on the right.
Installing, operating, and maintaining expeditionary airfield systems — short airfield for tactical support (SATS) equipment including catapults, arresting gear, optical landing systems, runway lighting, and aircraft recovery systems. You make it possible for Marine aircraft to operate from austere, forward airfields that would otherwise be unusable. When a location needs an airfield and there isn't one, your equipment and expertise create one.
Conducting marine safety inspections, reviewing vessel plans, investigating marine casualties, and enforcing safety regulations. You are a regulatory engineer ensuring vessels are safe to operate.
MCT at Camp Geiger (NC) or Camp Pendleton (CA) followed by the Expeditionary Airfield Systems Course at MCAS Cherry Point (NC). Training covers expeditionary airfield systems, catapult and arresting gear operations, optical landing system setup, and field maintenance procedures. Duration approximately 10-14 weeks.
Engineering degree required for commissioning. Marine safety engineering training follows at the Coast Guard's marine safety training pipeline.
High. Installing, maintaining, and repairing heavy airfield equipment in field conditions. The work involves heavy lifting, working outdoors in all weather, and physically demanding equipment operations.
Low to moderate. Vessel inspections require boarding ships and accessing engineering spaces.
Expeditionary Airfield Systems Technician is one of the most niche and underappreciated MOSs in Marine aviation. You install and maintain the catapults, arresting gear, lighting, and recovery systems that allow Marine aircraft to operate from expeditionary airfields — short, rough strips in forward locations that no civilian aircraft would land on. The recruiter probably didn't mention this MOS at all, because it's small and specialized. What they won't tell you: the equipment is heavy, the work is physical, the field conditions are austere, and almost nobody outside of Marine aviation knows you exist. But your work is genuinely critical: without expeditionary airfield systems, Marine aviation is limited to established bases, which defeats the entire purpose of the Marine Corps' expeditionary mission. The civilian career path is narrow but real: naval aviation support contractors, airport operations, and heavy equipment maintenance roles value this specific experience. It's not glamorous, but it's essential.
Marine Safety Engineer is a niche but rewarding career for engineers who care about maritime safety. The honest truth: it is regulatory work — inspecting vessels, reviewing designs, and investigating when things go wrong. Not glamorous, but intellectually satisfying and consequential. The civilian career path to classification societies, maritime insurance, and naval architecture firms is clear and well-compensated.
