After the Navy he was hired into six federal career fields and tech sales, and sat on federal hiring panels along the way. The last two years went into rebuilding all of it into BMR, tuned for how resumes get screened today. 75,916 resumes built so far.
As a 3522 Automotive Intermediate Technician, you worked the deeper end of Marine Corps motor transport maintenance. Where the 3521 Automotive Organizational Mechanic handles operator and unit-level service, the 3522 takes the components that come off the truck and rebuilds them: engines, transmissions, transfer cases, differentials, fuel-injection systems, and electrical harnesses on the MTVR, the LVSR, the HMMWV, and the JLTV. You diagnosed faults the organizational shop could not, tore the assembly down to the bearing, measured tolerances, replaced the failed part, and built it back to spec.
The training pipeline ran through Marine Corps Combat Service Support Schools at Camp Johnson, North Carolina, where intermediate automotive maintenance is taught at the Motor Transport Maintenance Instruction Company. You learned engine theory, drivetrain rebuild, electrical and electronic diagnostics, hydraulic systems, and the test-measurement-and-diagnostic equipment that intermediate shops run. Duty stations clustered around the big fleet maintenance facilities: Camp Lejeune, Camp Pendleton, Twentynine Palms, Okinawa, and the maintenance battalions inside the Combat Logistics Regiments.
Civilian employers value this background because the 3522 is not a parts-swapper. You read a no-start, a hard-shift, or an intermittent charging fault and traced it to root cause across mechanical, hydraulic, and electrical systems. That diagnostic depth is exactly what dealerships, fleet shops, and heavy-equipment yards are short on. BMR has built more than 60,000 resumes across every branch, and the pattern with intermediate automotive and diesel techs is consistent: the work translates the moment you name the systems and the rebuild scope in civilian shop terms instead of Marine Corps line numbers. Explore adjacent paths on the military career crosswalk, and if you want the language side handled, see how military maintenance experience maps to civilian trade careers.
I have watched 3522 resumes go from invisible to interview-getting with one change: naming the actual rebuilds. "Performed intermediate-level maintenance" says nothing to a shop foreman. "Diagnosed and overhauled diesel engines, transmissions, and electrical systems on tactical wheeled vehicles" reads like a master tech. The work was always there. The resume just had to say it in his language. — Brad Tachi, Navy Diver veteran & BMR founder
The number that decides most of this: how does civilian pay compare to what the paycheck looks like now?

BLS median across the direct-match civilian roles on this page.
Federal, GS-9 to GS-13
$58K to $120K

About 22% lower on average
Civilian base pay for Automotive Intermediate Technicians runs about $15K below mid-career enlisted total comp, though housing comes out of that number on the military side too.
Military comp is approximate and moves with location and dependents. Civilian is the BLS median. Federal includes locality pay. The real number depends on duty station, family status, GS step and overtime.
The diagnostic and rebuild depth a 3522 brings lines up with some of the better-paying skilled-trade roles, and the demand is real. The Bureau of Labor Statistics projects steady openings in vehicle maintenance through 2032, driven by an aging technician workforce and the complexity of modern engine and emissions systems. Salary figures below are BLS Occupational Employment and Wage Statistics medians, May 2024.
Automotive Service Technician (BLS median $47,770) is the broad on-ramp, but your intermediate background means you should target the higher-skill specialties rather than entry oil-change bays. Diesel Engine Specialist / Bus and Truck Mechanic (BLS median $59,160) is the closest 1:1 to your tactical-truck work and where the strongest demand sits. Mobile Heavy Equipment Mechanic (BLS median $62,540) suits anyone who logged time on the LVSR or recovery vehicles. Master Technician status, built on ASE certification, is where the pay ceiling opens up at dealerships and large fleets.
Be honest about the market: pay tracks specialization and certification, not just years turning wrenches. Diesel and heavy-vehicle work pays more than light-duty automotive, and shops in freight corridors, mining, agriculture, and construction regions pay above metro dealership rates. Veterans coming out of Army 91B Wheeled Vehicle Mechanic and Navy CM Construction Mechanic roles compete for the same diesel and fleet jobs, so the resume that names ASE-equivalent work specifically is the one that gets the call.

Federal hands-on vehicle maintenance is largely Wage Grade (WG/WS), not General Schedule, and that is good news for a 3522: WG jobs hire on demonstrated trade skill, and your intermediate maintenance record is the qualifying experience. The big employers are the Defense Logistics Agency, Marine Corps Logistics Command in Albany and Barstow, Army depots, GSA fleet, the VA, and the National Park Service.
WG-5823 Automotive Mechanic and WG-5803 Heavy Mobile Equipment Mechanic are the direct matches; both hire at journeyman wage-grade levels where your rebuild experience qualifies you outright. WG-5806 Mobile Equipment Servicing is the adjacent service-and-PM role. WG-5350 Production Machinery Mechanic fits depot and shop-equipment work. On the General Schedule side, GS-0802 Engineering Technician suits maintenance-engineering and fleet-analysis roles, GS-1910 Quality Assurance fits depot QA and inspection, and GS-1601 General Facilities and Equipment covers fleet and equipment management. Veterans' Preference adds 5 or 10 points to your standing and matters most on the GS series, which draw heavier applicant pools than the WG trade jobs.
Start your search on USAJobs by filtering for the WG-5823 and WG-5803 series near the maintenance depots. The qualification standard for WG trades is a job-element rating, so your resume must describe the specific systems you rebuilt and the diagnostic equipment you ran. Veterans from Coast Guard MK Machinery Technician backgrounds target these same WG series. For how veterans' preference and the federal hiring process actually work, read how 10-point veterans' preference works, and when you are ready, start your federal resume.

Not everyone stays in a related field. These paths run on the transferable half of the job: leadership, risk, logistics, planning.
The electrical troubleshooting you did on vehicle charging and lighting systems is the foundation of line work, and the comfort with high-current circuits and hazardous conditions transfers directly.
Transfers: Vehicle electrical and charging-system diagnostics, High-current wiring and harness repair, Hazardous-condition risk management, Working aloft and under physical stress.
How to get there: Apply to a utility lineworker apprenticeship (often union-run, paid). No degree required; some employers value a CDL and prior electrical exposure, which a 3522 already has.
BLS OEWS May 2024 · 7% (Faster than average)
Avionics is electronic troubleshooting on a different platform. The schematic-reading and signal-tracing you did on vehicle electrical and electronic systems is the same core skill, applied to aircraft.
Transfers: Electronic fault isolation, Reading wiring schematics, Precision diagnostic instrument use, Documentation to regulatory standard.
How to get there: Earn an FAA repairman or an FCC license plus avionics training (GI Bill funds A&P/avionics programs). Some manufacturers train on the job for qualified electronics techs.
BLS OEWS May 2024 · 5% (Faster than average)
HVAC blends mechanical, electrical, and pressurized-fluid systems, the exact mix a 3522 worked daily. The diagnostic logic carries over; only the equipment changes.
Transfers: Hydraulic and pressurized-system diagnostics, Refrigerant and fluid handling, Electrical control troubleshooting, Reading system schematics.
How to get there: Complete an HVAC certificate program (GI Bill eligible) and earn EPA 608. Many techs start as installers and move into service and diagnostics within a year.

How to get there: Take a short PV certificate (NABCEP-aligned, GI Bill eligible at many schools) or start as an apprentice installer. Entry is fast; certification raises pay.
BLS OEWS May 2024 · 22% (Much faster than average)
Factory machinery fails the same ways vehicles do: mechanical wear, hydraulic leaks, electrical faults. A 3522 who can rebuild a transmission can rebuild a production-line gearbox; the diagnostic method is identical.
Transfers: Mechanical, hydraulic, and electrical fault diagnosis, Component overhaul to tolerance, Preventive-maintenance program execution, Precision measurement.
How to get there: Most employers train on the job for skilled mechanics. A CMRT or millwright credential and any PLC familiarity accelerate placement into higher-pay plant roles.
BLS OEWS May 2024 · 13% (Much faster than average)
You already trained junior Marines on the shop floor. Community colleges and high schools need automotive-technology instructors, and your bench credibility plus that teaching instinct is exactly the profile they hire.
Transfers: Teaching and mentoring junior mechanics, Breaking complex repairs into steps, Shop safety enforcement, Hands-on technical instruction.
How to get there: Most states offer an alternative or CTE teaching credential for experienced tradespeople; an ASE Master plus years of experience often substitutes for a degree. GI Bill can fund the education courses.
BLS OEWS May 2024 · 1% (Little or no change)
Running a shop section means managing people, parts, schedules, and uptime targets. That is operations management. The throughput and accountability mindset from a Marine maintenance section transfers to any facility.
Transfers: Maintenance NCO team supervision, Parts inventory and procurement control, Readiness and downtime metrics, Scheduling and workflow planning.
How to get there: Start as an operations coordinator or maintenance supervisor. A PMP or Six Sigma Green Belt accelerates the move into broader operations leadership.

If you are staying in automotive, diesel, or fleet maintenance, your terminology translates directly. Shop foremen know what a transmission rebuild and a charging-system diagnosis are. This section is for the 3522 targeting careers OUTSIDE hands-on vehicle maintenance, where a hiring manager has never seen a Marine Corps maintenance line number and needs the work in plain business language.
| Military Term | Civilian Translation |
|---|---|
| Intermediate-level maintenance | Component-level diagnostics and overhaul |
| TMDE (test, measurement, diagnostic equipment) | Precision diagnostic and calibration instruments |
| MTVR / LVSR / JLTV | Heavy-duty diesel and tactical wheeled vehicle fleet |
| Layette / parts requisition | Parts inventory control and procurement |
| SL-3 completeness inspection | Equipment readiness and accountability audit |
Before: "Performed intermediate-level automotive maintenance on motor transport assets in accordance with the MIMMS." After: "Diagnosed and overhauled diesel engines, transmissions, and electrical systems on a 40-vehicle heavy fleet, reducing deadline time and documenting every repair in a digital maintenance management system." That second version reads to a hiring manager in any industry that runs equipment. For the full method, see the 50 military terms translated to civilian language glossary and how to explain military experience in a civilian interview. The veteran resume builder does this translation as you type.

Placement decides whether a screener ever sees it. BMR knows where each one ranks, what to call it, and how to frame it.
Free to start. Built around your real certs and clearance.
The fastest paid credential is ASE certification. The A-series (A1 through A9) covers engine repair, transmission, electrical, brakes, and diesel engines, and the Master Automobile Technician status that comes from passing the set is what dealerships and large fleets pay a premium for. Many of your intermediate tasks already map to ASE test content, so you are testing on work you have done, not learning it cold. SkillBridge placements with dealership groups, Penske, Ryder, and fleet operators let you finish active duty inside a civilian shop. Industry associations worth joining: the TMC of American Trucking Associations for fleet, and the Automotive Service Association.
If you are leaving wrenches behind, the transferable credentials are project management (CAPM or PMP), Six Sigma for process roles, and OSHA 30 for safety tracks. American Corporate Partners (ACP) offers free veteran mentorship to map the jump. Compare fields on the 3537 Motor Transport Operations Chief path and other motor-T roles, and the federal resume builder if you are targeting WG or GS work.

The closest matches are Diesel Engine Specialist and Bus/Truck Mechanic (BLS median $59,160, May 2024), Mobile Heavy Equipment Mechanic (BLS median $62,540), and Automotive Service Technician (BLS median $47,770). Your intermediate rebuild background points you toward the higher-skill diesel and heavy-equipment roles rather than entry light-duty bays. Master Technician status, built on ASE certification, opens the pay ceiling at dealerships and large fleets.
Not to get hired, but it raises your pay and your ceiling fast. Many shops will hire a 3522 on demonstrated skill and pay for the ASE tests after. Because your intermediate maintenance work already covers engine, transmission, electrical, and diesel content, you are largely testing on work you have done. Master Automobile Technician status (passing the A-series set) is what commands the premium.
The BLS Occupational Employment and Wage Statistics median for Bus and Truck Mechanics and Diesel Engine Specialists was $59,160 in May 2024. Pay runs higher in freight corridors, mining, agriculture, and construction regions, and higher again for techs who hold ASE diesel certifications and can run modern emissions and electronic-control diagnostics.
Your diagnostic reasoning, failure-analysis discipline, and ability to run complex systems under deadline transfer to fields well outside a shop. The career-change section on this page lists different-industry destinations such as power-systems and HVAC roles, manufacturing maintenance leadership, and technical training, each with its own retraining path. The transferable skill is structured troubleshooting, not just turning wrenches.
Yes, and federal hands-on vehicle maintenance is largely Wage Grade rather than General Schedule. WG-5823 Automotive Mechanic and WG-5803 Heavy Mobile Equipment Mechanic are direct matches that hire on demonstrated trade skill. The Defense Logistics Agency, Marine Corps Logistics Command in Albany and Barstow, Army depots, GSA fleet, and the VA all hire these series. Search USAJobs by series code near the maintenance depots.
Veterans' Preference adds 5 or 10 points to your standing on competitive federal jobs and can break ties in your favor. It matters most on the GS series, which draw larger applicant pools than the WG trade jobs where your hands-on experience already does the heavy lifting. You verify preference with your DD-214 during the federal application, which is the one place that document belongs.
Yes. The GI Bill can fund approved automotive and diesel technology programs at community colleges and trade schools, many of which build directly toward ASE certification. Some employers and manufacturer programs are also approved for benefits. See our GI Bill trade school guide for the current program list and how to apply.
Lead with specific diagnoses and rebuilds, not duty titles. Describe a hard intermittent fault you traced to root cause, the components you overhauled, and the readiness or downtime result. Hiring managers in any equipment-running industry understand that story even if they have never heard of an MTVR. Avoid acronyms and line numbers; name the systems in plain shop language.
Diesel and heavy-vehicle demand is strongest along freight corridors and in regions with heavy agriculture, mining, construction, and trucking. Light-duty automotive work is everywhere but pays less. If you are mobile, targeting fleet-heavy regions raises both your offer rate and your pay. BLS projects steady openings nationwide through 2032 as the technician workforce ages out.
Begin 12 to 18 months out. That window lets you line up a SkillBridge placement with a dealership group or fleet operator like Penske or Ryder, sit for ASE tests, and build a resume that names your rebuild scope before terminal leave. Starting late forces you into whatever job is open rather than the higher-paying specialty you actually qualify for.
