Track Vehicle Repairer

The strongest direct path for a 91H is heavy-diesel and mobile-equipment maintenance. The Bureau of Labor Statistics (BLS OEWS, May 2024) reports a median annual wage of $62,740 for heavy vehicle and mobile equipment service technicians (O*NET 49-3042.00), the category that covers mechanics on bulldozers, cranes, graders, and other tracked and off-road machines. Bus and truck mechanics and diesel engine specialists (49-3031.00) sit close behind at a $60,640 median, and the work translates almost directly from a tracked power pack to a Class 8 truck or transit-bus drivetrain.

Industrial machinery mechanics (49-9041.00) earn a $63,510 median per BLS May 2024, working in manufacturing plants where the skill is the same logic applied to stationary production equipment instead of a hull. If you spent time on vehicle climate-control systems, HVAC and refrigeration mechanics and installers (49-9021.00) carry a $59,810 median. Automotive service technicians (49-3023.00) sit lower at $49,670, generally a step down from heavy-diesel pay.

Be honest with yourself about the market. Heavy-equipment and diesel work is steady and geographically broad, but the best-paying seats cluster around mining regions, ports, construction corridors, and large fleet operators. Dealer technician roles for Caterpillar, John Deere, and Komatsu often pay more than independent shops but expect manufacturer certification. Other branches feed the same civilian pipeline, so it is worth seeing how the Marine Corps 2147 LAV repairer and the Navy Construction Mechanic (CM) map their experience. For a sense of where these wages land against other transitions, the military-to-civilian salary guide is a useful gut check, and a clean, ATS-ready resume from the military resume builder keeps the heavy-diesel keywords where the scanner can find them.

Federal maintenance work is one of the cleanest landings for a 91H because the government runs its own tracked and heavy fleets, and it hires for them under the Federal Wage System (WG) rather than the GS scale. The closest match is WG-5803 Heavy Mobile Equipment Mechanic, the exact federal trade for someone who repaired tracked vehicles, recovery vehicles, and construction equipment. You will find WG-5803 billets at Army depots, Marine Corps logistics bases, National Guard combined support maintenance shops, and across the Defense Logistics Agency. WG-5823 Automotive Mechanic covers the lighter end of the same skill set.

From there the federal options widen. WG-5306 Air Conditioning Equipment Mechanic fits anyone who worked vehicle and facility climate systems. WG-5352 Industrial Equipment Mechanic and WG-5350 Production Machinery Mechanic apply if you move into a depot or arsenal maintaining plant machinery. On the GS side, GS-1601 General Facilities and Equipment and GS-0346 Logistics Management are the administrative ladder a maintenance NCO climbs into for planning, fleet management, and maintenance-control roles. Qualification for WG trades is built on demonstrated hands-on experience, which your Army maintenance record documents directly, so the screening question is whether the resume proves the specific systems you worked.

Veterans get a real edge here. Veterans Preference adds 5 or 10 points to your score on most competitive federal jobs, and several special hiring authorities let agencies bring veterans on without competing through the public announcement at all. The mechanics of proving preference and writing experience to the WG standard trip a lot of people up, so it is worth reading the Veterans Preference points breakdown and the guide to finding your federal job-series equivalent before you apply. The how-to-write-a-federal-resume guide covers the format, and the federal resume builder structures it to the WG/GS standard automatically.

If you are staying in heavy-diesel or mobile-equipment maintenance, your terminology already translates. Fleet shops, dealers, and mining operations use the same words you do, so do not water down a resume aimed at them. This section is for 91Hs targeting careers outside vehicle maintenance, where a hiring manager has never heard a single term on your evaluation.

The bullet rewrite is where callbacks are won. A military bullet reading "Performed field-level maintenance on M113 FOV and supervised recovery operations during NTC rotation" should become, for a fleet operations resume, "Led diagnostics and repair of diesel-powered tracked equipment across a 40-vehicle fleet, including drivetrain, hydraulic, and electrical systems, achieving 95% operational readiness under field conditions." For an operations or facilities role, "Managed maintenance scheduling and parts accountability for a heavy-equipment fleet, coordinating inspections and corrective work across multiple worksites." The work is identical; only the language changed. For the full method, the military-experience translation guide and the 50 military terms glossary are the references to keep open, and the resume builder handles the formatting so you can focus on the wording.
