7566 vs 6672
Pilot, CH-53E/K Super Stallion / King Stallion (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."
On one side of the military: the 53 community is tight — HMH squadrons are smaller than other type/model communities and the aircraft demands respect from everyone who flies it. Three engines, seven rotor blades, and the physical workload of flying a 73,000-pound helicopter requires genuine strength and endurance. And in this corner: the supply system is large, bureaucratic, and frequently slow relative to operational demand. 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. Filed under: two jobs that no civilian could accurately compare, which is why this page exists.

Recruiter vs. Reality
The pitch versus what people who actually did the job report back.
“You'll fly the largest helicopter in the Western military arsenal — the CH-53E/K can lift a Light Armored Vehicle, carry 55 combat-loaded Marines, or externally sling 36,000 pounds of cargo. Heavy-lift pilots are in constant demand because nothing else can move what the 53 moves.”
The CH-53 is a massive, powerful, and demanding aircraft. Three engines, seven rotor blades, and the physical workload of flying a 73,000-pound helicopter requires genuine strength and endurance. The missions are unique to heavy-lift: external loads that smaller aircraft can't touch, assault support where you're putting an entire reinforced platoon on an objective, and TRAP (tactical recovery of aircraft and personnel) missions. The 53 community is tight — HMH squadrons are smaller than other type/model communities and the aircraft demands respect from everyone who flies it. The CH-53K King Stallion is the newest variant and the most advanced heavy-lift helicopter ever built. Civilian heavy-lift helicopter experience is niche but the multi-engine turbine hours are valuable for any rotary-wing career path.
“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. 7566 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.
