After the Navy I got hired into 6 federal career fields and tech sales, and sat on federal hiring panels along the way. I spent the last 2 years rebuilding everything I learned into BMR, tuned for how AI actually screens resumes today. This is the system I wish I'd had on day one.

Machine Gunners (0331) are the Marine Corps' crew-served weapons specialists, responsible for the tactical employment of the M240B medium machine gun, M2 .50 caliber heavy machine gun, and MK19 automatic grenade launcher. They provide suppressive fire, area denial, and fire support to infantry units during offensive and defensive operations.
0331s attend Machine Gunner Course at the School of Infantry (SOI-West at Camp Pendleton, CA or SOI-East at Camp Lejeune, NC) following Marine Combat Training. The course covers weapons maintenance, ballistics, fire planning, range estimation, and tactical employment of crew-served weapons. Machine Gunners are assigned to weapons companies in infantry battalions across the Marine Corps — 1st through 3rd Marine Divisions and reserve units.
Beyond the weapons proficiency, 0331s develop skills that many civilians and employers overlook: they manage complex equipment inventories, conduct detailed maintenance programs, plan and coordinate supporting fires across a battlefield, and lead small teams under extreme stress. The fire support coordination and equipment maintenance discipline — not just the combat experience — is what transfers to civilian careers.
Machine gunners carry the same translation problem 0311s face, and the resume solution is the same — small-unit leadership, weapons systems mastery, and operational decision-making under pressure. 0331s convert into security operations, industrial supervision, and federal LE roles when the resume reframes the work in civilian terms. The skills are there; the words are the problem. — Brad Tachi, Navy Diver veteran & BMR founder
The number that matters when you're deciding what's next: how does civilian pay compare to what you make now?
Military comp is approximate (varies by location/dependents). Civilian is BLS median. Federal includes locality pay. Your real number depends on duty station, family status, GS step, and overtime.
Machine Gunners transitioning to the private sector face a straightforward reality: there is no civilian job that involves operating crew-served weapons. The transition requires reframing skills rather than finding a direct match.
The strongest private sector paths leverage the operational discipline, equipment expertise, and leadership that define the 0331 MOS. Security and protective services (BLS median $38,370 for security guards, $74,960 for supervisors) are common entry points, but they are not the only — or highest-paying — options. Operations management ($102,950), logistics ($80,880 with 17% growth per BLS), and law enforcement ($76,290 for police officers) all draw on the planning, team coordination, and accountability that 0331s develop in the fleet.
Defense contractors also hire former infantry Marines for weapons system training, technical writing, and program support roles — particularly companies that manufacture or maintain the weapon systems 0331s operated.

“Hey Brad, Just wanted to send out a quick thank you. You've created something amazing with BMR and your continued advocacy for transitioning service members does not go unnoticed. It was the most effective resource I used in my transition and I know it played a key role in landing a six figure…”
Federal employment provides multiple pathways for Machine Gunners. Law enforcement and security are the most obvious matches, but the federal government also hires for logistics, program management, and training positions where infantry experience is valued.
GS-0083 Police and GS-0085 Security Guard positions at DOD installations, VA medical centers, and federal courthouses directly leverage your tactical awareness and discipline. GS-1896 Border Patrol Agent positions are competitive matches — CBP specifically values the physical fitness, fieldwork endurance, and team-based operations that define infantry service. For 0331s with leadership experience, GS-0301 Administrative and GS-0340 Program Management positions are accessible through demonstrated planning, coordination, and resource management skills. Veterans' Preference applies across all of these.

Not everyone wants to stay in a related field. These career paths leverage your transferable skills — leadership, risk management, logistics, project planning — in completely different industries.
Climbing a turbine to service it demands the same hazard tolerance, physical endurance, and methodical maintenance mindset a machine gunner brings to keeping a gun in the fight. The danger does not faze you.
Restoring power on a live line after a storm is high-stakes crew work where a wrong move kills. The decision-under-fire and team-in-chaos instincts of a gun team transfer directly.
Keeping a machine gun running flawlessly under stress is the same discipline that keeps an aircraft airworthy: exacting maintenance, zero tolerance for shortcuts, full ownership of the outcome.
An operating room under a trauma case is controlled chaos where the team has to stay calm and move fast. A machine gunner who has worked casualties under fire already thinks that way.
Drilling a gun team to standard and pushing Marines through brutal conditioning is coaching. Translating that into civilian strength and fitness training is a natural, credibility-rich move.
Tearing down, troubleshooting, and rebuilding a machine gun under stress is the same mechanical problem-solving a plant needs when a production line goes down. The pressure makes it routine for you.
The skills that made you a good Marine, Sailor, Airman, or Soldier transfer further than you think. BMR rewrites your bullets for any of the pivot careers above — without making you sound like you've never done the work.

If you are applying to a defense contractor for a weapons-related role or to law enforcement, your terminology is largely understood. But if you are targeting operations management, logistics, project management, or any corporate role, the hiring manager has never seen a fire support coordination plan and does not know what PMCS means.
The translations below convert 0331 experience into business language for non-military, non-law-enforcement roles. These are not just word swaps — they show how to frame your machine gunner experience in terms that corporate hiring managers can evaluate.
BMR turns your 0331 duties and accomplishments into civilian bullets that match the job you're applying for — no manual translation, no rewriting.

Most veterans do this backwards — they wait until terminal leave to start, then panic. Here's the actual sequence that works.
Print this. Tape it to your monitor. Veterans who treat the transition like a 90-day op get hired faster than the ones who treat it like an emergency.
Stop rewriting from scratch every time you apply. BMR turns your military experience into civilian and federal resumes — tailored to each job.
