Brad TachiNavy Diver · BMR founder
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. 76,598 resumes built so far.
As a 91S Stryker Systems Maintainer, you kept the eight-wheeled Stryker family running. Infantry Carrier Vehicles, Mobile Gun Systems, command variants, ambulances, and engineer squad vehicles all rolled back into the fight because you found the fault and fixed it. You worked the full stack: air, fuel, electrical, hydraulic, brakes, steering, pneumatics, powertrain, air conditioning, suspension, and the armament interface. The Stryker is not a simple truck. It is a computerized platform, so a big part of the job was plugging into diagnostic equipment, reading fault codes, and isolating problems across electrical and electronic systems before you ever turned a wrench.
The training pipeline ran through the Wheel Maintenance Training Department at the U.S. Army Ordnance School. You came out an apprentice-level maintainer credentialed and EPA 609 certified in mobile air conditioning service, with the course qualifying for up to 12 hours of college credit (source: goordnance.army.mil). That mix matters on the civilian side. You are not just a wrench. You diagnose electronic faults, you document repairs to a standard, and you keep a fleet mission-capable under a clock.
Civilian employers pay for that exact profile. Diesel and heavy-equipment shops, fleet operations, and electrical-diagnostic roles all need people who can troubleshoot a complex machine instead of guessing at it. If you want to see where the 91S skill set maps across the economy, start with the military career crosswalk tool. Two related Army maintenance pages worth a look are the 91B Wheeled Vehicle Mechanic path and the 91M Bradley Fighting Vehicle System Maintainer path, which share the diagnostic-heavy, fleet-readiness side of the work.
I was a Navy Diver, never a 91S, but I have watched BMR build more than 60,000 resumes and the maintenance folks lose interviews for one reason: they list the platform instead of the diagnosis. A hiring manager does not know what a Stryker is. They know what "isolated electrical faults across a 19-vehicle fleet and held readiness above 90 percent" means. Translate the work, not the vehicle. — 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?

About 15% lower on average
Civilian base pay for Stryker Systems Maintainers runs about $11K 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 civilian market for vehicle and heavy-equipment technicians is steady, and the diagnostic edge a 91S brings pays a premium over swap-the-part mechanics. Here is what the BLS Occupational Employment and Wage Statistics (May 2024) reports for the roles that line up with Stryker maintenance.
Mobile heavy equipment mechanics earn a median of $62,740, and BLS projects heavy vehicle and mobile equipment service technician employment to grow 6 percent from 2024 to 2034, faster than average. Construction, mining, ports, and rental fleets all hire this profile. Bus and truck mechanics and diesel engine specialists sit at a $60,640 median (BLS, May 2024); the field grows a slower 2 percent through 2034 as some fleets shift away from diesel, so geography and employer matter.
Industrial machinery mechanics post a $63,510 median and a strong 13 percent projected growth (BLS, May 2024), which makes a plant-maintenance role one of the more durable landing spots if you want off the road. If you lean into the electronic-diagnostic side of Stryker work, electro-mechanical and mechatronics technicians earn a $70,760 median (BLS, May 2024). Automotive service technicians run lower at a $49,670 median, so treat dealership work as a floor, not a target.
Be honest with yourself about the market. Diesel demand is regional, dealership pay is soft, and the best money goes to technicians who can run the diagnostic computer and read a wiring schematic, not just replace components. That is your lane. For a broader view of how maintenance experience translates, the military to trade careers guide walks through several skilled paths, and the military to HVAC technician guide shows how your EPA 609 cert opens an adjacent door. Two cross-branch maintainers with near-identical wheeled-vehicle work are the Marine 2147 LAV Repairer and the Air Force 2T3X1 Vehicle Maintenance roles. When you are ready to put this on paper, you can build your resume now.

Federal vehicle maintenance runs on the Wage Grade (WG) trades system more than the GS scale, and that is good news for a 91S. WG jobs hire on demonstrated skill, not degrees, and your Ordnance School training plus hands-on Stryker time maps cleanly to several series.
The closest match is WG-5803 Heavy Mobile Equipment Mechanic, which covers exactly the diesel, hydraulic, electrical, and powertrain work you did. WG-5823 Automotive Mechanic fits lighter wheeled fleets, and WG-5806 Mobile Equipment Servicing is a solid entry point if you are stacking experience. On the electronic-diagnostic side, WG-2805 Electrician recognizes the electrical fault-isolation work that sets Stryker maintainers apart. Agencies that run large vehicle fleets hire these series constantly: the Army and Marine Corps depots, the Defense Logistics Agency, the U.S. Postal Service vehicle maintenance facilities, the National Park Service, and the General Services Administration fleet program.
If you want to move toward planning and oversight rather than the wrench, GS-1670 Equipment Specialist is the bridge: it values people who know a platform inside out and can write specifications, manage modifications, and advise on fielding. Veterans preference applies to all of these, and a strong federal resume needs the hours-per-week and month-year format that civilian resumes skip. Start with the 10 federal job series every veteran should search, then read how to write a federal resume before you apply. A cross-branch maintainer who targets the same WG series is the Marine 3523 LVS Mechanic. When your federal draft is ready, you can get started here.

Not everyone stays in a related field. These paths run on the transferable half of the job: leadership, risk, logistics, planning.
Stryker maintainers already break complex systems into measurable failure points; that same analysis improves manufacturing lines and reduces downtime.
Transfers: Electronic fault isolation with diagnostic equipment, Reading wiring schematics and technical documentation, Root-cause troubleshooting on complex systems, Process and reliability data collection.
How to get there: Start as a technician with a community-college industrial-tech certificate or associate degree; Lean or Six Sigma training accelerates the move into process roles.
BLS OEWS May 2024 · As fast as average
The electronic-diagnostic half of Stryker work maps to telecom hardware; you already test, isolate, and repair signal-carrying systems.
Transfers: Electronic systems troubleshooting, Signal and continuity testing, Schematic-driven fault isolation, Documentation of installs and repairs.
How to get there: A fiber-optic or telecom-technician certificate plus an entry installer role; carriers and contractors train on their specific equipment.
BLS OEWS May 2024 · Slower than average
Maintainers who held readiness under pressure and understood electrical loads adapt well to monitoring and balancing a power grid where mistakes are costly.
Transfers: Monitoring system status under load, Reacting to faults in real time, Electrical systems knowledge, Strict procedure and safety compliance.
How to get there: Utilities hire on aptitude and train on systems; a power-systems certificate or utility apprenticeship plus passing the utility aptitude battery is the usual route.
BLS OEWS May 2024 · Little or no change
Aviation is a different industry but rewards the same discipline: diagnose a complex machine, fix it to standard, and sign off with documentation that holds up.
Transfers: Systems-level diagnostics across hydraulics and electrical, Work to strict inspection and documentation standards, Hands-on repair of high-consequence equipment, Fault isolation under time pressure.
How to get there: An FAA Airframe and Powerplant certificate is the gate; some military maintenance experience may count toward eligibility, and the GI Bill funds A&P school.
BLS OEWS May 2024 · Faster than average
If you were the one who chased electrical gremlins across the Stryker electronic architecture, avionics pays a premium for that exact instinct.
Transfers: Electronic fault diagnosis on integrated systems, Bench and in-system testing, Calibration and signal tracing, Precision documentation.
How to get there: An FAA repairman or avionics certificate, or an associate degree in avionics; aviation employers also sponsor type-specific training.
BLS OEWS May 2024 · Faster than average
A 91S already plugs into diagnostic systems, reads fault codes, and isolates problems across electrical and electronic systems before turning a wrench. A control-room operator does the same at plant scale, watching instruments and acting inside a hard procedure.
Transfers: Reading computerized diagnostics and fault codes, Monitoring instrumented systems under load, Electrical and electronic systems knowledge, Strict procedure and safety compliance.
How to get there: Utilities hire and train operators, with NERC certification common for the role. No degree needed. Your diagnostic and procedure-driven Stryker maintenance background maps directly onto a trainee operator seat.

If you are staying in vehicle and heavy-equipment maintenance, your terminology already translates. A diesel shop and a fleet operation know what a Stryker maintainer does. This section is for careers OUTSIDE vehicle maintenance, where a hiring manager has never heard of an Infantry Carrier Vehicle and needs the skill, not the platform.
The fix is to name the transferable skill and quantify it. Here is how the military language becomes business language.
| Military framing | Civilian framing |
|---|---|
| Diagnosed Stryker electrical faults with STE/ICE diagnostic equipment | Used computerized diagnostic systems to isolate electrical and electronic faults, reducing repeat repairs |
| Maintained fleet readiness for a Stryker company | Sustained operational availability across a 19-asset fleet under strict uptime targets |
| Performed field-level maintenance per technical manuals | Executed preventive and corrective maintenance to documented procedures and safety standards |
| EPA 609 certified, serviced vehicle A/C systems | Certified to service refrigerant systems in compliance with federal environmental regulations |
Notice what changed. The civilian version leads with the skill an employer can price, then adds a number. A maintenance manager hiring for a manufacturing plant does not care that it was a Stryker. They care that you isolate faults on complex machinery and keep availability high. The 50 military terms translated to civilian language glossary is built for exactly this, and quantifying military accomplishments shows how to attach the numbers. You can also let our military resume builder handle the translation while you focus on the wins worth listing.

Free to start. Built around your real certs and clearance.
If you want to keep turning wrenches on complex machines, stack civilian-recognized credentials on top of your Army training. ASE certifications (Automotive Service Excellence) are the industry standard for vehicle technicians, with separate tests for medium and heavy trucks. Your EPA 609 mobile A/C certification already carries over. SkillBridge gives you a runway to train with a civilian employer before you separate, and apprenticeships through programs like Helmets to Hardhats connect maintainers to fleet and equipment shops. For a wider scan of skilled-trade routes, read the military to trade careers guide.
If you are done with vehicles, your diagnostic and systems skills travel. Manufacturing plants need electro-mechanical and mechatronics technicians. Utilities, aviation MRO shops, and telecom all hire people who can troubleshoot electronic systems. Lean on American Corporate Partners (ACP) for free veteran mentorship as you change lanes, and use the GI Bill or VR&E for the retraining a true career change needs. The what career field should I pick after the military guide helps you choose, and how to explain military experience in a civilian interview preps you for the conversation.

Your closest matches are mobile heavy equipment mechanic (BLS median $62,740, May 2024), bus and truck mechanic or diesel engine specialist ($60,640), industrial machinery mechanic ($63,510), and electro-mechanical or mechatronics technician ($70,760). The diagnostic side of Stryker work, isolating electrical and electronic faults with test equipment, is what separates you from swap-the-part mechanics and earns the higher end of those ranges.
Per BLS Occupational Employment and Wage Statistics (May 2024), mobile heavy equipment mechanics earn a median of $62,740 and bus and truck mechanics earn $60,640. Pay rises with diagnostic and electronic-systems skill and with employer type. Construction, mining, port, and rental fleets generally pay more than dealerships.
It is mixed. BLS projects heavy vehicle and mobile equipment service technicians to grow 6 percent from 2024 to 2034, faster than average. Bus and truck and diesel specialists grow a slower 2 percent as some fleets move away from diesel. Industrial machinery mechanics, a strong off-the-road option, grow 13 percent. Where you live and which fleet you target both matter.
Federal vehicle maintenance runs mostly on Wage Grade trades. WG-5803 Heavy Mobile Equipment Mechanic is the closest fit, with WG-5823 Automotive Mechanic, WG-5806 Mobile Equipment Servicing, and WG-2805 Electrician also in scope. GS-1670 Equipment Specialist is the bridge into planning and oversight. Agencies with large fleets, the Defense Logistics Agency, USPS, GSA, and the National Park Service, hire these series regularly.
No. Most vehicle and heavy-equipment roles, and the federal Wage Grade series, hire on demonstrated skill rather than a degree. ASE certifications and your existing EPA 609 mobile A/C credential carry more weight than a diploma for hands-on work. A degree helps if you target engineering-technician or management tracks later.
Your fault-isolation and systems-troubleshooting skills travel well. Different-industry options include electro-mechanical and mechatronics technician ($70,760), industrial engineering technician ($64,790), telecommunications equipment installer and repairer ($64,310), aircraft mechanic ($78,680), avionics technician ($81,390), and power distributor and dispatcher ($103,600), all BLS May 2024 medians. Each needs some retraining or certification, which the GI Bill or VR&E can fund.
Yes. EPA Section 609 certification for servicing motor vehicle air conditioning systems is a federal credential, so it transfers directly to civilian shops. List it by name on your resume, since it shows you can legally handle refrigerants and it signals you already meet an environmental compliance requirement many employers screen for.
Veterans Preference adds points or moves you into a higher consideration category for competitive federal positions, including the Wage Grade and GS series above. You verify it with your DD-214 during the federal application, not on your resume content. Read our federal resume guide for the exact format hiring panels expect.
Lead with the diagnosis and the number, not the platform. A civilian manager does not know what a Stryker is, so write "isolated electrical and electronic faults across a fleet and held readiness above 90 percent" instead of listing vehicle variants. Our military resume builder translates the work automatically. You can get started here.
Heavy-equipment and diesel demand concentrates around construction, mining, ports, agriculture, and freight corridors, so Texas, the Gulf Coast, the Midwest, and the Mountain West tend to have deep markets. Manufacturing-heavy regions favor the industrial-machinery and mechatronics paths. BLS area wage data lets you compare specific metros before you commit to a move.
