0313 vs 0302
Light Armored Vehicle Crewman (USMC) vs Infantry Officer (USMC)
Two Marines in the chow hall: one smells like the field, the other like hydraulic fluid. Both think they have it worse. Both are right.
Here are two things that happen simultaneously in the same armed forces. Thing one (0313): you are technically in the 03 infantry field, but you are not a grunt — you crew a vehicle. Thing two (0302): 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. Both of these fall under the same Defense Department. Both involve the same GI Bill. Everything between those two facts is different. The ratings below are from people who actually did these jobs. The blurb above is from us. Trust the ratings.
After the Uniform
The part the recruiter skips: what each job actually translates to once you're a civilian — and what it pays.

The pitch versus what people who actually did the job report back.
“You'll crew one of the fastest armored vehicles in the Marine Corps — the LAV-25, an eight-wheeled reconnaissance vehicle with a 25mm chain gun. LAV units are the Marine Division's eyes and ears, conducting reconnaissance and security missions ahead of the main force. You'll learn vehicle gunnery, mounted tactics, and how to fight from a platform that gives you firepower and speed that dismounted infantry doesn't have. It's an infantry MOS with a vehicle, which means you get the best of both worlds — combat arms credibility and a technical skill set.”
This MOS lives in an identity crisis and the Marines in it will tell you about it. You are technically in the 03 infantry field, but you are not a grunt — you crew a vehicle. You don't do the things that define infantry life (long patrols, living in the dirt for weeks, the traditional infantry brotherhood), but you also don't get the respect or resources that dedicated vehicle communities like tanks used to get. You are somewhere in between, and neither side fully claims you. The LAV-25 itself is a Cold War-era platform that has been upgraded but is fundamentally aging. Your 25mm Bushmaster chain gun is effective but the vehicle's armor will not stop anything serious — it's light armored, emphasis on light. You are fast and you are mobile, which is the point — LAV units screen, recon, and provide security. You are not meant to slug it out with heavy armor. Training at Camp Pendleton covers vehicle operation and gunnery basics, but like most MOSs the real learning is in the fleet. The morale issue is real: LAV battalions are small, school seats for career-enhancing courses often go to the grunt battalions first, and the promotion path can feel stagnant compared to 0311s who have more billets and more visibility. The Force Design 2030 restructure is also hanging over this community — the Marine Corps divested tanks entirely and the future of LAV units is an open question as the Corps moves toward lighter, more dispersed formations. Civilian translation is thin — there is no civilian LAV. The discipline, teamwork, and mechanical aptitude transfer, but you'll need to build a resume beyond "I crewed an armored vehicle" to compete in the job market. Use TA while you're in.
“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. 0313 on the left, 0302 on the right.
Gunnery drills, mounted reconnaissance, vehicle maintenance, and field training. LAR Marines spend significant time in the motor pool maintaining LAV-25s — these vehicles are old and require constant attention. Field time is heavy. When garrison, expect PT, ranges, maintenance, and training packages.
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 SOI (School of Infantry), you attend the LAV Crewman Course at Camp Pendleton. Training covers LAV-25 operations, gunnery, reconnaissance fundamentals, and vehicle maintenance. The course is hands-on and physically demanding. Expect a lot of time in the turret and in the field.
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.
Very high. You combine infantry fitness requirements with the demands of operating the LAV-25. Mounted and dismounted operations, turret drills, and reconnaissance patrols in all terrain and weather. Expect to be crammed into a hot vehicle for hours, then dismount and patrol on foot.
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.
LAR Marines occupy a unique niche between infantry and armor. The recruiter might not even mention this MOS — it's overshadowed by the 0311 pipeline. The reality: you get more technical training, a reconnaissance mission, and vehicle-based firepower that standard infantry doesn't have. The downsides are real: the LAV-25 fleet is aging, maintenance is constant, and 29 Palms — where many LAR units are based — is one of the most isolated bases in the military. Promotion is slow because the community is small. The camaraderie is tight, the mission is interesting, and the skills (vehicle operations, gunnery, reconnaissance) translate to security contracting and defense industry roles.
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.
