7051 vs 6672
Expeditionary Firefighting and Rescue (EFR) Specialist (USMC) vs Aviation Supply Specialist (USMC)
The Marine Corps promised both of these would "make you a leader." The methods range from "forging in fire" to "death by PowerPoint."
Two promises walked into a recruiting station. The first: "maintain the airfields that marine corps aviation operates from, managing runway conditions, aircraft parking, and the ground infrastructure critical to flight operations." The second: "marine aviation runs on parts." Both promises were technically true in the way that "water is involved in surfing" is technically true about the Navy. 7051 reality: fOD (foreign object debris) walks — walking the runway looking for things that could be ingested by an engine — are the defining meditative experience of this MOS. 6672 reality: the supply system is large, bureaucratic, and frequently slow relative to operational demand. Both branches will tell you theirs is the hardest. Neither will concede. This is tradition.

“Maintain the airfields that Marine Corps aviation operates from, managing runway conditions, aircraft parking, and the ground infrastructure critical to flight operations. Airfield services specialists ensure that every aircraft can launch, recover, and be serviced safely regardless of operating environment.”
FOL and expeditionary airfield operations are where this MOS earns its existence. Building and maintaining an expeditionary airfield — FARP operations, AM-2 matting installation, FOB strip preparation, MOGAS and AVGAS fuel point setup — is the engineering-adjacent, aviation-supporting work that enables Marine air to operate forward of established installations. The airfield marking, lighting, and arresting gear systems at permanent installations are your domain too. You will work in the wake jet blast of aircraft that are not designed to accommodate the people servicing the areas around them. FOD (foreign object debris) walks — walking the runway looking for things that could be ingested by an engine — are the defining meditative experience of this MOS. The work is physical, weather-exposed, and often unacknowledged by the aviators who depend on it being right. Airport operations and airfield management civilian careers are the natural transition. FAA certifications are accessible. The understanding of how an airfield actually functions from the ground up is a perspective most aviation professionals never develop.
“Marine aviation runs on parts. As an Aviation Supply Specialist, you are the link between the maintenance department and the supply system — the person who gets the right component, in the right condition, to the right technician before NMCS status turns into a cancelled mission. You manage aviation spare parts inventories for Marine squadrons: ordering, receiving, inspecting, storing, and issuing aircraft components and aeronautical consumables. You interface with Aviation Supply Depots, process requisitions for Not Mission Capable Supply aircraft, manage bench stock so routine items are always on hand, and track high-value assets through the supply chain. Aviation supply is not general supply with a different hat — the urgency is real, the documentation requirements are precise, and the consequences of a wrong part or a lost tracking number show up on the flight schedule.”
Aviation supply at the squadron level means you will be the person maintenance chiefs come to — loudly, urgently — when an aircraft has been down for parts for three days and the CO is asking questions. The supply system is large, bureaucratic, and frequently slow relative to operational demand. Knowing how to navigate NALCOMIS, how to escalate a priority requisition, and how to source a part through lateral transfer when the depot pipeline is dry is what separates a good 6672 from one who just processes paperwork. The MOS also requires understanding enough about the parts you're tracking to recognize when something is wrong — a component returned from repair that doesn't match the documentation, or a consumable that doesn't match the NSN. Deployments mean supporting aviation supply in expeditionary conditions with reduced staffing and compressed timelines. The work is administrative at its surface and operationally critical underneath.
The Real Life
Same dimensions, side by side. 7051 on the left, 6672 on the right.
—
Receiving, storing, issuing, and tracking aviation-specific parts and supplies. Operating aviation logistics information systems, managing repairable components, and supporting aircraft maintenance shops with the parts they need. You work in aviation supply warehouses and tool rooms, interfacing between maintenance Marines and the supply chain.
—
The Aviation Supply Specialist Course covers aviation supply procedures, parts identification, hazardous materials handling, and aviation-specific logistics systems. The training is more specialized than general supply — you learn aircraft-specific inventory management and the unique requirements of aviation parts tracking.
—
Moderate. Aviation supply work involves receiving, storing, and issuing aircraft parts — some of which are heavy and require careful handling. Warehouse work and hazmat handling are part of the job.
—
Aviation supply specialists are the enlisted Marines who ensure aircraft maintenance shops have the right parts at the right time. The recruiter won't know what to tell you about this MOS. The honest truth: it's warehouse and logistics work with an aviation specialization that makes it significantly more marketable than general supply. The civilian aviation industry is massive — airlines, defense contractors, MRO facilities, and aircraft manufacturers all need supply chain workers who understand aviation parts. Starting salaries for experienced aviation supply professionals are $45,000-$65,000, with management potential well above that. The work is detail-oriented and the stakes are real — the wrong part on an aircraft can be catastrophic. If you're organized, detail-oriented, and want a career in the aviation industry without being a mechanic or a pilot, this MOS is a solid foundation.
