Assault Amphibious Vehicle (AAV)/Assault Combat Vehicle (ACV) Repairer/Technician

As a 2141, the MOS now titled AAV/ACV Repairer/Technician and formerly the Assault Amphibious Vehicle Repairer/Technician, you kept the amphibious fleet running. You inspected, maintained, and repaired the automotive and turret systems on the AAV family of vehicles, and you ran field-level and operator maintenance from the maintenance bay to the recovery vehicle in the surf zone. You worked diesel powerpacks, hydraulics, suspension and final drives, electrical systems, and the recovery rig itself. With the Corps retiring the AAV and fielding the ACV (Amphibious Combat Vehicle), the MOS now spans both platforms, so many recent 2141s have hands on both legacy tracked hulls and the new 8x8 wheeled ACV.

The pipeline runs through the Assault Amphibian School aboard Camp Pendleton, where the Basic Repairer Course awards the MOS over roughly 55 training days of automotive and hull maintenance under supervision. Entry requires an MM line score of 105 and a class III swimmer qualification. From there you typically land at an Assault Amphibian Battalion at Camp Pendleton or Camp Lejeune, or with a unit at Camp Hansen, Okinawa.

Here is the part that matters for your next job. Civilian employers do not hire AAVs or ACVs. They hire the skill underneath: a diesel and heavy-equipment mechanic who diagnoses hydraulics, tears down and rebuilds powerpacks, runs final drives and suspension, and keeps complex machinery mission-capable in brutal conditions. That is a $60,000-plus trade the second you put it in language a shop foreman understands. If you want to see how your skills map across the whole field, the military career crosswalk tool lays it out, and Marines in the same maintenance family like the 2147 Light Armored Vehicle Repairer and the 1142 Engineer Equipment Mechanic share most of the same civilian paths.

A 2141 hits the translation wall hard, because "Assault Amphibious Vehicle Repairer" reads to a civilian shop manager like a job that does not exist outside the Marine Corps. It does exist. You are a tracked and wheeled heavy-diesel mechanic who rebuilds powerpacks, troubleshoots hydraulics, and runs final drives. Put it on paper that way and the callbacks come. — Brad Tachi, Navy Diver veteran & BMR founder

The trade you learned on the AAV and ACV maps cleanly onto some of the most stable mechanical jobs in the country. Diesel and heavy-equipment shops are short on techs who can actually diagnose, and that shortage shows up in the pay.

Mobile heavy equipment mechanics (O*NET 49-3042) and the broader heavy vehicle and mobile equipment service technician category earned a median of $62,740 in May 2024 per BLS, with the top 10 percent over $89,920. BLS projects 6 percent growth from 2024 to 2034 and roughly 21,700 openings a year. Bus and truck mechanics and diesel engine specialists (O*NET 49-3031) sat at a $60,640 median, and industrial machinery mechanics (O*NET 49-9041) at $63,510. Move into the supervisor seat and first-line supervisors of mechanics, installers, and repairers (O*NET 49-1011) ran a $74,070 median.

Be honest with yourself about geography. The best diesel and heavy-equipment money clusters around construction booms, mining regions, ports, and energy corridors. Dealer service networks (Caterpillar, John Deere, Komatsu) and large fleet operators pay for ASE and brand-specific certifications, so the techs who chase factory training move up fastest. The work is cyclical with construction, but the equipment never stops needing maintenance, which is why the field stays resilient through downturns.

Companies that already hire this background range from heavy-equipment dealers to defense maintainers who service the actual platforms you worked on. If you would rather translate the same diesel and hydraulics skill into aviation, civilian veterans coming out of the same maintenance world often look at the Navy CM Construction Mechanic and Army 91L Construction Equipment Repairer paths, which land in the same shops. For the trades view of where this leads, our breakdown of military to trade careers is worth a read, and you can build your resume now when you are ready to apply.

Federal maintenance work is one of the most underused exits for a 2141, and it pays on the Wage Grade (WG) and General Schedule (GS) scales rather than guesswork. The single closest match is the WG-5803 Heavy Mobile Equipment Mechanic series. That is your job, almost word for word, working on tactical and construction equipment at depots, installations, and Defense Logistics Agency sites. Pair it with WG-5823 Automotive Mechanic for wheeled-fleet shops and WG-5350 Production Machinery Mechanic for industrial maintenance.

From there the federal field opens wider than most Marines expect. WG-5378 Powered Support Systems Mechanic and WG-5306 Air Conditioning Equipment Mechanic cover support and environmental systems, WG-2810 Electrician (Aircraft) fits if your electrical troubleshooting was strong, and WG-1670 Equipment Services plus WG-5704 Forklift Operating and WG-6907 Materials Handler are common entry rungs in a maintenance shop. If you move toward shop management, GS-0301 Miscellaneous Administration and Program covers maintenance-program and logistics-coordination roles.

Veterans' Preference applies on competitive federal jobs and gives you 5 or 10 points depending on your service and disability status. The Department of Defense, Marine Corps Logistics Command, and the Army's depots at Anniston and Red River all run heavy-equipment maintenance shops that recognize exactly what a 2141 brings. To get the application right, our guide to the military skills to federal job series match walks through the crosswalk, and you can start your federal resume here. Marines from the same maintenance family, like the Army 91H Track Vehicle Repairer, target these same WG series.

If you are applying to a diesel shop, an equipment dealer, or a federal maintenance series, your terminology already translates. Those hiring managers know what a powerpack and a final drive are. This section is for 2141s targeting careers OUTSIDE heavy-equipment maintenance, where a hiring manager has never heard of an AAV and will skim past anything that sounds like jargon.

The fix is not to dumb it down. It is to name the civilian function and attach a number.

Here is how that looks on a resume aimed at a non-military reader. Before: "Performed field-level maintenance on the AAV family of vehicles and operated the AAV recovery vehicle." After: "Diagnosed and repaired diesel powerpacks, hydraulic systems, and final drives across a fleet of tracked and wheeled heavy equipment, and operated recovery equipment to return disabled vehicles to service, sustaining over 90 percent fleet readiness." The second version gets read because it speaks the shop's language and ends in a result.
