Fire Control Repairer

As a 91G Fire Control Repairer you kept the targeting systems on the M1A1 Abrams and the M2 Bradley shooting straight. You ran the Digital System Electronic Support Test Set (DSESTS) to drive off-system diagnostics, isolated faults down to the Line Replaceable Module, and pulled and swapped optical sights, laser rangefinders, thermal imagers, gun turret drive electronics, and the precision instruments that let a crew put steel on target the first time. This is electro-mechanical and optronics repair at a tolerance most civilian shops never touch.

The work sits inside CMF 91 (Mechanical Maintenance). You trained at the U.S. Army Ordnance School at Fort Gregg-Adams, learning fault diagnostics, calibration, component substitution, and the discipline of repairing systems where a fraction of a degree of error means a miss. Most of your day was test, measure, isolate, repair, verify. That loop is exactly what civilian calibration labs, avionics benches, and industrial automation floors run on.

Civilian employers value 91Gs because the skill is rare and provable. You read schematics, you operate automated test equipment, you document to a standard, and you do precision work without a supervisor checking every step. If you want to see how your skill set maps across other Army maintenance jobs, the 91H Track Vehicle Repairer and 91D Power Generation Equipment Repairer pages cover adjacent CMF 91 paths, and the military-to-civilian career crosswalk lets you compare destinations side by side. For the resume itself, our guide to converting NCOER bullets into resume language is the place to start.

I never wore the 91G badge. I was a Navy Diver, and BMR has built more than 60,000 resumes across every branch and MOS. The pattern I see with fire control repairers is consistent. The skill is elite, but "fire control repairer" reads as a riddle to a civilian recruiter who has never heard of a DSESTS. The job is not to oversell the work. It is to name the civilian equivalent (calibration, avionics, electro-mechanical repair) so a hiring manager recognizes it in six seconds. — Brad Tachi, Navy Diver veteran & BMR founder

The most direct civilian match for a 91G is precision electro-mechanical and instrument repair, and the pay is solid. Per BLS OEWS (May 2024), electro-mechanical and mechatronics technologists and technicians earn a median of $70,760, and electrical and electronics repairers of commercial and industrial equipment earn a median of $71,270. Avionics technicians, who do near-identical bench work on aircraft systems, earn a median of $81,390. Calibration technologists and technicians, the closest match to your test-and-measure discipline, earn a median of $65,040.

Be honest with yourself about geography and industry. Avionics and aerospace roles cluster around aviation hubs and defense corridors (Wichita, Fort Worth, Huntsville, the DC-Maryland-Virginia belt). Calibration and metrology labs follow manufacturing and pharma. Industrial machinery and automation roles, where electrical and electronics repairers of commercial and industrial equipment fit, are spread wider across the Midwest and Southeast. The clearance and defense-contractor track keeps you near where the Army already buys weapons systems, and that is where your specific DSESTS and fire control experience is worth the most.

Defense primes hire 91Gs to sustain the same platforms you worked on. If you want to stay close to the gun line, look at roles supporting Abrams and Bradley fielding. For a broader view of contractor hiring, our breakdown of defense contractor jobs and the companies that hire veterans is worth a read. Cross-branch, the Navy Fire Controlman (FC) and the Air Force 2A0X1 Avionics Test Station and Components ratings feed the same civilian benches, so the same employers post for all of you. When you are ready to write it up, the military resume builder translates the systems work into plain hiring language.

Federal service is a strong fit for 91Gs because the government runs the same arsenals, depots, and calibration labs you already know. Many of the matching positions are Wage Grade (WG) trade roles rather than GS, which is normal for hands-on repair work. The WG-2604 Electronics Mechanic series is the closest fit, covering technicians who troubleshoot, repair, and modify electronic equipment at depots like Anniston Army Depot, Tobyhanna Army Depot, and Navy and Air Force maintenance centers. WG-3359 Instrument Mechanic and the related Optical Instrument Repair work (3306) cover the precision-instrument and optronics side of your background directly.

On the GS side, the GS-0856 Electronics Technician series is the path for technicians who move into test engineering support, and GS-0802 Engineering Technician covers broader technical roles in program offices and labs. As you add education or certifications, GS-0855 Electronics Engineering and GS-1910 Quality Assurance open up for those who move toward inspection, acceptance testing, and reliability work.

Veterans' Preference adds 5 or 10 points to your federal application score, and several depot hiring actions use direct-hire and veteran-specific authorities. Read the announcement's qualification section carefully, because WG jobs screen on demonstrated hands-on ability and GS jobs screen on specialized experience plus education. For how to write the federal version, see our 2026 federal resume format guide and the federal job series every veteran should search. The federal resume builder handles the OPM structure so you do not lose points on formatting.

If you are staying in electronics, avionics, or calibration, your terminology already translates. A metrology lab or an avionics shop knows what a test set and a Line Replaceable Module are. This section is for careers OUTSIDE fire control and electronics repair, where a hiring manager has never seen your jargon and needs the civilian version.

The fix is to lead with the outcome and the standard, not the equipment nomenclature. Translate the system into what it accomplished and how precisely you held the tolerance. Here is how that reads on a resume aimed at a non-electronics role.

• Before: "Used DSESTS to fault-isolate M1A1 fire control LRMs." After: "Operated automated diagnostic test equipment to isolate faults in complex electro-mechanical systems, restoring mission-critical assets to full capability within tolerance."
• Before: "Maintained turret optics and laser rangefinder per TM." After: "Calibrated and repaired precision optical and laser instruments to documented specifications, ensuring measurement accuracy across high-value equipment."
• Before: "Cleared faults on gun turret drive electronics." After: "Diagnosed and resolved electronic and servo-control failures under deadline pressure, documenting each repair to an auditable standard."

The skill that travels furthest is not a single system. It is your habit of working to a measurable tolerance and documenting it. Build that into every bullet.
