6602 vs 0302
Aviation Supply Officer (USMC) vs Infantry Officer (USMC)
Two MOS codes that share nothing except a fierce, eternal argument about who's more "Marine." Spoiler: neither will concede.
The 6602 recruiting pitch and the 0302 recruiting pitch both used the word "opportunity." The 6602's version of opportunity: ' 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? The 0302's version: deployment means your Marines' lives depend on your tactical decisions — route selection, patrol base placement, fire coordination, and the split-second calls that determine whether a situation escalates or resolves. Two definitions. Same dictionary. Different planets. One military. Two completely different answers to "what do you do?" at a party.

“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.
“Infantry Officers lead the most elite fighting force on the planet. IOC is the gold standard of military leadership training, producing officers who command in the chaos of close combat. You'll lead Marines at the tip of the spear and develop decision-making skills that Fortune 500 CEOs study. This is the ultimate test of leadership.”
You are an Infantry Officer in the Marine Corps, which means you went through TBS (The Basic School) where every Marine officer starts and then IOC (Infantry Officer Course) where most Marine officers don't finish. IOC's attrition rate is legendary and intentional — the Marine Corps only wants infantry officers who can handle the physical and intellectual demands of leading Marines in combat. Your first assignment is a rifle platoon: 40 Marines who are simultaneously the most capable and most creatively destructive people you've ever led. Your platoon sergeant has been an infantry Marine since before you graduated high school, and your working relationship with them determines whether your platoon succeeds or suffers. The infantry officer's job is to close with and destroy the enemy through fire and maneuver, which is a sentence that sounds simple and takes a career to master. Deployment means your Marines' lives depend on your tactical decisions — route selection, patrol base placement, fire coordination, and the split-second calls that determine whether a situation escalates or resolves. The peacetime garrison mission is training: ranges, field exercises, and the constant cycle of preparation that keeps an infantry platoon ready. The physical demands are the highest of any officer MOS. The leadership experience is the deepest. Defense consulting, federal law enforcement, intelligence agencies, and corporate leadership programs actively recruit Marine infantry officers at $70-120K.
The Real Life
Same dimensions, side by side. 6602 on the left, 0302 on the right.
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.
Planning operations, leading training, conducting counseling, writing evaluations, and managing the administrative burden of 30-50 Marines' lives. You are simultaneously a tactician, mentor, counselor, and bureaucrat. Good days are in the field running live fires. Most days involve more paperwork than trigger time.
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.
The Basic Officer Course (TBS) at Quantico is 6 months and every Marine officer goes through it regardless of MOS. Infantry Officer Course (IOC) follows — 13 weeks of the most physically and mentally demanding officer training in the military. IOC has a significant attrition rate. Expect sleep deprivation, forced marches with 100+ lbs, and constant tactical evaluation.
Low to moderate. Aviation supply work is primarily warehouse and office-based, with some physical demands in managing aviation parts and equipment.
Extreme. You are expected to outperform every Marine in your platoon on every physical event. Rucking, running, swimming, obstacle courses — you lead from the front and your body takes the same beating as your 0311s, plus the mental load of command.
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.
Being a Marine infantry officer is one of the most demanding leadership positions in the world. The recruiter and the OSO will sell you the glory — and the pride is real. What they won't tell you: IOC will break you physically and mentally, and roughly 25% of candidates don't make it. If you do make it, you get 2-3 years of platoon command that will define you for life, followed by a series of staff billets that feel like a different job entirely. The Marine Corps is up-or-out, and not everyone who wants to stay can. The civilian transition is strong — Marine infantry officers are highly recruited by consulting firms, tech companies, and government agencies — but only if you prepare for it. The leadership experience is unmatched. The lifestyle cost is enormous.
