0370 vs 6602
Special Operations Officer (USMC) vs Aviation Supply Officer (USMC)
Both went to Parris Island or San Diego. Everything since has been a choose-your-own-adventure book with no good options.
If time travel were real and you could send one message to yourself at MEPS, the 0370 version would be: "Your pipeline is one of the most demanding in all of special operations, and the Marines who work for you are among the most capable fighters in any military, anywhere." And the 6602 version: "' When an aircraft is grounded for a part, the entire chain of command knows, and the first question is always 'where's the supply officer?" Your past self would sign anyway. They always do. Two branches that could not agree on a lunch spot, let alone a joint operational concept.
After the Uniform
The part the recruiter skips: what each job actually translates to once you're a civilian — and what it pays.

Recruiter vs. Reality
The pitch versus what people who actually did the job report back.
“Special Operations Officers lead Marine Raiders -- the most elite special operations forces in the Marine Corps. You'll command direct action raids, special reconnaissance, and foreign internal defense missions across the globe. MARSOC officers are the pinnacle of military leadership, operating in the shadows where strategic impact is measured in global outcomes.”
You are a Special Operations Officer, which means you lead MARSOC operators in the kind of missions that nobody at your 20-year high school reunion would believe and that you can never confirm or deny. Your pipeline is one of the most demanding in all of special operations, and the Marines who work for you are among the most capable fighters in any military, anywhere. You'll operate in small teams, in places that don't appear on public maps, doing things that make the news without attribution. Your FITREP will never adequately describe what you did. Your family will never fully understand what you do. But the operators you lead will know, and their respect is the only review that matters in this community.
“Aviation Supply Officers manage the complex logistics that keep Marine Corps aircraft mission-ready across the globe. You'll oversee multimillion-dollar aviation supply chains, master repairable component management, and develop expertise that aviation and defense companies eagerly recruit. You are the unsung hero of Marine air power.”
You are an Aviation Supply Officer managing parts for aircraft that cost $80 million each, which means a single requisition error can ground an aircraft worth more than most people will earn in multiple lifetimes. Your readiness metrics are briefed to wing commanders and directly affect whether Marine aviation can execute its mission. You manage a supply chain that includes DLA, OEM procurement, lateral transfers from other units, and the creative cannibalization process where you rob one aircraft to keep another flying (and track every part with religious precision). Your supply Marines process thousands of transactions per month, and your inventory accuracy must support aircraft maintenance schedules that have zero margin for 'we'll get the part next week.' When an aircraft is grounded for a part, the entire chain of command knows, and the first question is always 'where's the supply officer?' You manage high-value repairable components worth millions, expendable items that cost pennies but are mission-essential, and hazmat materials that require specialized handling and documentation. The aviation supply mission is relentless because aircraft readiness never pauses. Civilian aviation logistics, defense contractor supply chain management, and airline parts management positions recruit Marine aviation supply officers at $75-110K.
The Real Life
Same dimensions, side by side. 0370 on the left, 6602 on the right.
Mission planning, advanced tactical training, language study, partner force coordination, and deployment preparation. MARSOC operators train at a level that conventional Marines rarely experience. The operational tempo is high and the training budget is significantly better than conventional units. Expect extensive travel, both TDY and deployed.
Managing aviation supply operations, overseeing procurement of aircraft parts, maintaining aviation-specific inventory systems, tracking repairable components, and ensuring aircraft maintenance shops have the parts they need. Aviation supply is more technical than general supply — you need to understand aircraft systems well enough to manage the parts that keep them flying.
Assessment & Selection (A&S) is followed by the Individual Training Course (ITC) — roughly 9 months of advanced tactics, weapons, communications, medical, and language training. The pipeline is long, demanding, and has significant attrition. Officers must already have infantry or reconnaissance experience before applying.
After TBS, Aviation Supply Officers attend specialized supply training focused on aviation logistics, DLA (Defense Logistics Agency) procedures, and aviation-specific supply systems. The training builds on basic supply officer skills with aviation-specific knowledge.
Elite-tier. MARSOC selection (A&S) is one of the most physically demanding assessments in SOCOM. Open-water swims, extended rucks, obstacle courses, and mental stress tests. Once assigned, you maintain peak fitness indefinitely — there is no "garrison mode" in special operations.
Low to moderate. Aviation supply work is primarily warehouse and office-based, with some physical demands in managing aviation parts and equipment.
MARSOC is the Marine Corps' contribution to SOCOM and it has matured significantly since its founding in 2006. The recruiter at an OSO office will mention it in passing — the real recruiting happens within the fleet. What they won't tell you: the selection process is brutal, the deployment tempo is relentless, and the impact on families and relationships is severe. Divorce rates in the special operations community are among the highest in the military. If you make it, you join an elite community with unmatched training, equipment, and mission sets. The post-military career options are outstanding: defense contracting, intelligence agencies, corporate security, and executive protection. But the cost — physical, mental, and relational — is real and often permanent.
Aviation supply officers manage the parts and logistics that keep Marine aircraft mission-capable. Without the right part at the right time, multi-million dollar aircraft sit on the deck doing nothing. The OSO won't lead with this MOS — supply isn't exciting on a poster. The reality: aviation supply chain management is a specialized skill that the civilian aviation industry values highly. Airlines spend billions on parts and maintenance logistics, and they need managers who understand the system. Your military experience managing aviation supply chains, DLA procurement, and readiness metrics translates directly. The work is administrative and can be bureaucratic, but the impact on aircraft readiness is tangible and the post-military career potential in aviation logistics is strong.
