Field Artillery Radar Operator

If you held the 0842 MOS, you ran counterfire target-acquisition radar for a Marine artillery unit. Your primary system was the AN/TPQ-53 Firefinder, a truck-mounted phased-array radar that tracks projectiles from mortars, artillery, and rockets in flight and back-plots their point of origin. You emplaced and bore-sighted the antenna, ran startup and initialization, loaded the digital terrain map, operated the set in hostile mode, and fed acquisitions into the Advanced Field Artillery Tactical Data System (AFATDS) so the guns could shoot back. You also laid wire, ran field telephones, kept the generator and power distribution alive, and performed preventive maintenance in the field.

Reaching the MOS meant a GT score of 105 or higher, U.S. citizenship, and a Secret security clearance, then the Marine Artillery Radar Operator Course at Fort Sill, Oklahoma. That course teaches phased-array radar theory, signal processing, system calibration, and electronic troubleshooting at a level most civilian jobs never train from scratch. That is the part civilian employers value: you operated and maintained a complex RF sensor system under field conditions, diagnosed faults without a depot behind you, and held a clearance the whole time.

This page is for Marines leaving the 0842 field who want to know what civilian work actually pays for that background. The strongest paths sit in radar, RF, and electronics technician work, but your sensor-systems experience also opens doors in avionics, telecom, and federal electronics roles. Explore the full set of branches and ratings in the military career crosswalk, and if you served alongside cannoneers, the 0811 Field Artillery Cannoneer and 0861 Fire Support Marine pages cover adjacent fire-support roles.

After the Navy I pivoted into tech sales, and the 0842 is one of the more underrated backgrounds for that move. You ran a phased-array radar and troubleshot RF and signal-processing faults in the field, which is a level of technical depth most sales engineers selling radar, RF, and defense electronics never reach. That credibility lets you sit across from an engineer-buyer and actually hold the conversation, which is exactly what opens doors at companies building sensor and electronic-warfare systems. — Brad Tachi, Navy Diver veteran & BMR founder

The clearest civilian match is electronics and RF technician work. The U.S. Bureau of Labor Statistics (BLS) Occupational Employment and Wage Statistics (OEWS), May 2024, reports a median wage of $77,180 for electrical and electronic engineering technologists and technicians, the bucket that covers radar and sensor-system test and repair. Avionics technicians, who work on aircraft radar, navigation, and communication systems, posted a median of $81,390. Telecommunications equipment installers and repairers came in at $64,310. These are honest mid-career numbers, and the AN/TPQ-53 experience maps to all three.

Demand is uneven by sub-field and geography. Defense electronics work concentrates around major contractor sites and military installations, while telecom and tower work follows carrier buildout and is steadier in metro markets. Avionics work clusters near airline maintenance bases and regional MRO (maintenance, repair, and overhaul) shops. If you want to stay close to radar specifically, defense contractors who build and field counterfire and air-surveillance systems hire former operators to do depot repair, field service, and customer training.

Several other branches produce people who compete for the same electronics and RF jobs, so their pages are worth reading for salary and employer context: Navy ET Electronics Technician, Air Force RAWS (1C8X3), and Army 25E Electromagnetic Spectrum Manager. For a broader look at how technical military jobs price out, the best tech careers for veterans without a degree guide is a useful starting point, and BMR can translate that experience into a tailored civilian resume when you are ready.

Federal service treats radar and electronics experience as specialized, not generic. The GS series that fit an 0842 background sit mostly in the technical and engineering-support families, and Veterans' Preference plus an active Secret clearance both count in your favor during referral.

The strong matches are GS-0856 Electronics Technician (radar, sensor, and RF system maintenance, the most direct fit), GS-2604 Electronics Mechanic (hands-on repair and overhaul of electronic equipment), and GS-0802 Engineering Technician (engineering support on sensor and systems programs). Adjacent series worth searching include GS-0391 Telecommunications (RF and comms systems), GS-2210 Information Technology Management (network and systems roles where your AFATDS data-systems exposure helps), and GS-0855 Electronics Engineering for those who finish a degree. The Department of Defense, Army and Navy depots, and agencies like the FAA hire heavily into 0856 and 2604.

Grades typically open at GS-7 to GS-9 for technicians with your hands-on time, with GS-11 reachable as you document supervisory or lead-tech responsibility. To translate radar duties into the language OPM referral panels score, the GS-0856 Electronics Technician federal resume guide and the specialized experience guide are the two to read first. Other electronics-adjacent military jobs target the same series, including the Navy Fire Control Technician (FT). BMR can then turn those duties into a USAJOBS-ready federal resume.

If you are staying in radar, RF, or electronics work, your terminology already translates. Hiring managers at defense contractors and MRO shops know what a phased-array set and a Firefinder are. This section is for Marines targeting careers OUTSIDE the electronics and sensor field, where AN/TPQ-53 and AFATDS mean nothing to the reader and need to be rewritten in business language.

The 50-term reference in 50 military terms translated to civilian language covers the common cases, and the hidden military skills piece helps you spot transferable strengths you may be underselling. Here is how a few 0842 duties read once they are rewritten for a non-technical hiring manager:

• Before: "Operated the AN/TPQ-53 Firefinder radar in hostile mode and back-plotted point of origin for counterfire missions." After: "Operated a complex real-time sensor system under time pressure, interpreting live data to produce accurate output that drove immediate decisions."
• Before: "Bore-sighted the antenna and performed startup, calibration, and initialization on the radar set." After: "Calibrated and configured high-value technical equipment to exact specifications before each operation, ensuring reliable performance with no margin for error."
• Before: "Diagnosed and corrected radar faults in the field without depot support." After: "Troubleshot and resolved equipment failures independently in remote conditions, minimizing downtime and keeping mission-critical systems available."
• Before: "Fed acquisition data into AFATDS for fire-mission routing." After: "Entered and validated time-sensitive data into an integrated command system, coordinating output across multiple teams."

Once you have the right civilian framing, the military resume builder turns these bullets into a finished resume.
