Heavy Ordnance Vehicle Repairer/Technician

The 2146 Heavy Ordnance Vehicle Repairer/Technician keeps the Marine Corps' heaviest combat power moving. You worked on tracked and heavy ground-combat vehicles such as the M1A1 Abrams main battle tank, the Assault Amphibious Vehicle family, and other tracked carriers. The job runs from the power pack and final drives to the hydraulics, fuel, electrical, and turret-related drive systems on platforms that weigh 60-plus tons. Diagnosis, removal and replacement of major assemblies, torque-critical reassembly, and road testing were all part of the day.

Training started at Marine Corps Detachment Fort Lee for the maintenance fundamentals, then moved into platform-specific instruction on tracked-vehicle powertrains, hydraulics, and electrical troubleshooting. On the line you logged maintenance actions, ordered parts, and read technical manuals and wiring diagrams to isolate faults on integrated systems. That is real heavy-equipment and diesel mechanic work: high-torque drivetrains, hydraulic systems running thousands of PSI, and complex electrical diagnosis under field conditions.

Civilian employers in construction, mining, transit, and heavy-equipment dealerships value this background because the platforms you maintained are more demanding than most commercial machines. If you want to see how this skill set lines up across the services, the military career crosswalk tool maps the related jobs. Inside the Corps, the 2147 Light Armored Vehicle Repairer/Technician and the 1142 Engineer Equipment Mechanic share much of the same diagnostic toolkit.

When I separated from the Navy I spent 18 months applying with no callbacks. The problem was never the work. It was how the resume read. For a 2146, "vehicle repairer" on paper sounds like an entry-level oil change to a hiring manager who has never seen a tank power pack come out. The fix is translating tracked-drivetrain, hydraulic, and diagnostic work into the heavy-equipment and diesel language civilian shops already pay for. Do that, and the callbacks come. — Brad Tachi, Navy Diver veteran & BMR founder

Your strongest civilian matches sit in heavy-equipment, diesel, and industrial maintenance. The Bureau of Labor Statistics tracks several of these occupations separately, so the salary figures below come straight from BLS OEWS May 2024.

Mobile heavy equipment mechanics earned a median of $62,740 in May 2024, with employment projected to grow 6 percent through 2034. These roles diagnose and overhaul cranes, dozers, graders, and other construction and mining equipment, which is the closest civilian parallel to tracked-vehicle work. Diesel service technicians earned a median of $60,640, and industrial machinery mechanics earned $63,510 with a strong 13 percent growth outlook, the fastest in this group. HVAC and refrigeration mechanics ($59,810) and automotive service technicians ($49,670) are accessible entry points if you want to broaden out. For technicians who lean into the electronics and automation side of modern drivetrains, electro-mechanical and mechatronics technicians earned $70,760, and experienced techs who move into aviation as aircraft mechanics earned $78,680.

Geography drives a lot of the pay difference. Construction and mining equipment work pays best where the work is, so dealership and rental-fleet roles cluster around major construction markets and resource regions. The industry is cyclical and tied to construction activity, so be honest with yourself about whether you want dealer-network stability or higher-paying but lumpier site and field-service work.

Marines from related tracked and wheeled maintenance fields compete for the same civilian jobs. See how the 3523 LVS Mechanic path overlaps, and across branches the Army 91H Track Vehicle Repairer and Navy CM Construction Mechanic chase nearly identical roles. If you are weighing the trades broadly, the military to trade careers guide and the free CDL training guide lay out adjacent options. When you are ready to put it on paper, build your resume now.

Federal maintenance work is one of the most direct landing spots for a 2146 because the government runs its own heavy fleets and pays through the Wage Grade (WG) trades system rather than only the GS scale. The clearest match is WG-5803 Heavy Mobile Equipment Mechanic, the federal classification for exactly the kind of tracked and heavy-vehicle work you did. Agencies like the Army at depots and arsenals, the Marine Corps logistics bases, and the Defense Logistics Agency hire heavily into this series.

Adjacent trades series include WG-5823 Automotive Mechanic for wheeled-fleet work, WG-5378 Powered Support Systems Mechanic for ground support equipment, WG-5350 Production Machinery Mechanic, and WG-5352 Industrial Equipment Mechanic at maintenance facilities. If you cross-trained on shop machining or fabrication, WG-3414 Machining is a path. Techs who move toward planning and oversight can target GS-0802 Engineering Technician, which sits on the GS scale and rewards the documentation and diagnostic-reporting habits you already built.

Veterans' Preference applies across these announcements, and the WG trades system often values demonstrated hands-on skill over formal credentials, which favors a hands-on Marine. Federal trades hiring frequently uses on-the-spot performance or skills-based screening, so a resume that spells out the specific platforms, systems, and torque/diagnostic procedures you mastered matters. The guide to finding your federal job series and the WG vs GS pay breakdown explain how the trades system works. The Army 91A M1 Abrams Tank System Maintainer page targets the same WG-5803 series.

If your target is another heavy-equipment, diesel, or fleet-maintenance shop, the words on your resume already line up with what those employers use. This section is for Marines targeting careers outside hands-on vehicle repair, where a hiring manager has never decoded a Marine maintenance record.

The trap is leaving your experience in military shorthand. A civilian reviewer does not know what an AAV power pack is, but they understand "removed and reinstalled a 60,000-pound vehicle's integrated diesel powertrain." Translate the platform, then quantify the work.

A few common before-and-after fixes:

• "Performed organizational and intermediate maintenance on tracked vehicles" becomes "Diagnosed and repaired diesel powertrain, hydraulic, and electrical systems on a fleet of heavy tracked vehicles, sustaining 95 percent operational readiness."
• "Used TM and electronic IETMs to troubleshoot faults" becomes "Read technical schematics and wiring diagrams to isolate complex hydraulic and electrical faults, reducing diagnostic time on recurring issues."
• "Conducted PMCS and submitted parts requests" becomes "Executed preventive maintenance schedules and managed parts ordering and inventory accountability for a high-value equipment fleet."

For the full vocabulary, the 50 military terms translated to civilian language glossary covers the most common offenders, and the hidden military skills guide helps surface accountability and troubleshooting experience civilians underrate. A military resume builder built for this translation does the heavy lifting on phrasing.
