Air Traffic Control Radar Technician

You are the hands on the equipment — cleaning antenna feeds, pulling cable, running PM checks, and learning to tell good radar returns from ground clutter. The technical manuals are your bible right now; you do not freelance.

Run preventive maintenance on the AN/TPX-42(V) radar and associated IFF interrogators under direct supervision. You assist with antenna drive system checks, verify transmitter power output readings, and log discrepancies in the equipment record. You pull coax connectors for inspection, reseat waveguide components, and learn the difference between a sweep rate anomaly and a corrupted display input. When the senior tech says "hold this" or "measure that," you are precise and you write it down.

• 01Preventive maintenance scheduling, technical manual interpretation, connector inspection and torque procedures, equipment logbook entries, basic RF safety practices, antenna mechanical inspection

• —Applicable TMs for AN/TPX-42(V), MCWP 3-25.8, NAVAIR 16-1-529 series, unit SOP

• —PM checks completed on schedule with no skipped line items, discrepancies logged same day with accurate symptom description, RF safety clearances observed without exception

• —Overtorquing waveguide flanges and stripping threads, failing to log a minor anomaly because it "went away," confusing IFF antenna port labeling and reconnecting leads to the wrong interrogator channel, skipping radome inspection because conditions looked clear

A junior 5953 who reads the TM before asking a question, logs every discrepancy with accurate symptom language, and never clears a PM line item they did not actually perform. You know which antenna drive faults are mechanical versus electrical, and you escalate before the problem becomes a flight-safety write-up.

You can now run an isolated fault-isolation sequence without a supervisor standing over you, and you are starting to own a piece of the maintenance cycle. Junior Marines watch how you work the TM and write the VIDS/MAF.

Perform corrective and preventive maintenance on the AN/TPX-42(V) radar system, IFF interrogators, and radar display equipment with limited supervision. You isolate faults to the LRU level using technical manual troubleshooting trees, order parts through the supply system, and document the full repair action in the maintenance management system. You assist with NTIA frequency deconfliction requests and help verify IFF Mode 3/C/S interrogation timing is within spec after any repair. You mentor one or two junior Marines on PM procedures and equipment handling.

• 01LRU-level fault isolation, VIDS/MAF documentation, IFF interrogator timing verification, supply system coordination, NTIA frequency deconfliction support, junior Marine mentoring

• —AN/TPX-42(V) TM fault-isolation chapters, FAAO 7110.65 equipment standards, unit frequency management SOPs, COMNAVAIRFORINST applicable volumes

• —Faults isolated to correct LRU on first attempt at or above unit benchmark rate, VIDS/MAF documentation complete and accurate before equipment is returned to service, IFF timing parameters verified within tolerance post-repair

• —Condemning an LRU based on symptom alone without completing the full isolation tree, submitting a VIDS/MAF with vague fault descriptions that do not support trend analysis, missing a frequency conflict because you assumed the previous deconfliction was still valid after a frequency reassignment

A Corporal who closes every corrective maintenance action with clean documentation, never shortcuts the isolation sequence, and catches the pattern — the same LRU failing twice in a month means a systemic issue, not bad luck. You flag that upstream before the third failure grounds the system.

You are the working technical lead — accountable for the quality of every maintenance action your section turns in and the first voice your Marines hear when something breaks at 0200 on a field op.

Lead a maintenance team through daily, weekly, and corrective maintenance on the radar suite, IFF interrogators, and associated display and processing equipment. You review and certify VIDS/MAF entries before submission, conduct maintenance quality-control checks, and are the primary troubleshooter when fault isolation exceeds junior tech capability. You manage the section's bench stock and monitor NMCS/PMCS status to brief the maintenance officer. In a MACS deployment environment you coordinate frequency deconfliction with adjacent units and the controlling ATC authority, and you verify IFF clutter suppression and radar sweep parameters are set correctly for the operational environment before the system goes mission-capable.

• 01Maintenance team leadership, QC review of maintenance documentation, advanced fault isolation including signal-path tracing, IFF Mode S interrogation parameter verification, NMCS/PMCS status reporting, frequency management in deployed environments, MACS deployment pre-mission checks

• —FAAO 7110.65, COMNAVAIRFORINST, MCO P4790.2 series (MIMMS), applicable TMs, NTIA manual, unit maintenance SOPs

• —Section maintenance documentation error rate within command threshold, zero return-to-shops attributable to incomplete fault isolation, IFF interrogation parameters verified correct before every operational period, NMCS status reported accurately and on time

• —Signing off a VIDS/MAF you did not personally verify because you trust your Marines and you are busy — that is how a bad repair reaches the flight line. Failing to recheck IFF sweep-rate correlation after a transmitter replacement. Letting a frequency conflict slide because "ATC said they would sort it" without documenting the deconfliction action yourself.

A Sergeant whose section turns in clean documentation, catches repeat failures early, and never sends a system to mission-capable status without a full operational check. When a radar anomaly shows up on a flight-safety debrief, your paper trail already explains exactly what was done, when, and by whom.

You run the maintenance section at the administrative and technical level simultaneously — training program, supply readiness, deployment planning, and still the most capable troubleshooter in the room when the hard fault walks in.

Manage all aspects of the radar maintenance section: training pipeline for junior technicians, bench stock and CASREP management, maintenance production scheduling, and technical oversight of all complex repair actions. You prepare and review equipment readiness reports for the commanding officer and maintenance officer, serve as subject matter expert on AN/TPX-42(V) capabilities and limitations during operational planning, and coordinate with MACS S-6 and adjacent units on frequency management and IFF plan synchronization. You identify systemic equipment degradation trends from maintenance data and submit engineering change recommendations or PQDR reports when warranted. You develop and run formal training events to qualify junior Marines on system-level maintenance tasks.

• 01Section management, maintenance production scheduling, CASREP preparation, equipment readiness reporting, IFF frequency plan synchronization, PQDR submission, systemic trend analysis from MIMMS data, formal maintenance training development

• —MCO P4790.2 (MIMMS), COMNAVAIRFORINST, FAAO 7110.65, applicable technical manuals, NTIA frequency management guidance, unit training SOPs

• —Equipment readiness reports accurate and submitted on time, no CASREPs attributable to deferred maintenance the section controlled, training qualification records current for all assigned personnel, IFF frequency plan synchronized and documented before each operational period

• —Allowing maintenance backlog to grow while chasing individual hard faults yourself instead of developing your techs. Submitting readiness reports with optimistic status because you expect the part to arrive — report what you have, not what you hope to have. Missing the PQDR window because you assumed the fault was operator error.

An SSgt whose section readiness data is trustworthy, whose junior Marines can run fault isolation independently, and who has a documented training record that survives PCS turnover. When the MACS deploys, your frequency plan is already coordinated and your system is mission-capable before the ramp brief.

You own the technical authority for radar systems across the squadron — the senior enlisted voice on equipment capability, employment limitations, and maintenance policy, and the person the commanding officer calls when an ATC radar discrepancy affects the flight schedule.

Serve as the senior technical advisor and section chief for all radar and IFF maintenance within the MACS. You set maintenance policy, resolve the highest-complexity fault isolation cases, review all CASREP and PQDR submissions before they leave the unit, and coordinate with higher headquarters on equipment modifications and technical manual changes. You advise the S-3 and operations officer on radar system employment limitations, IFF sector coverage constraints, and frequency deconfliction impacts on ATC operations. You manage personnel assignments within the section to match skill level to task complexity, and you own the training and qualification program from initial MOS school follow-on through advanced system certifications. You represent the unit in working groups on ATC radar modernization and sustainment.

• 01Senior technical authority, cross-section maintenance policy, CASREP and PQDR senior review, operational advisory on radar employment limitations, IFF sector planning, training program ownership, higher headquarters coordination, equipment modernization working group participation

• —FAAO 7110.65, COMNAVAIRFORINST, applicable TMs and technical bulletins, MCO P4790.2, NTIA, DoD IFF management publications

• —Zero mission-capable gaps attributable to preventable maintenance failures, all CASREP and PQDR submissions accurate and submitted within required timelines, training qualification records 100% current at all times, operational advisories to the commanding officer are technically correct and tactically relevant

• —Allowing yourself to become the single point of failure for complex fault isolation — if your section cannot function without you physically present, you have failed as a GySgt. Giving the operations officer an optimistic radar availability estimate because the conversation is easier — they will plan to that number and you will own the result.

A GySgt whose section runs clean maintenance cycles without his presence at every step, whose technical advisories to the commanding officer are consistently accurate, and who has built a training pipeline that produces capable Sergeants rather than dependent ones. When the unit gets the bad news on a complex system fault, your section already has a restoration timeline and the parts request is already submitted.

You set the technical and professional standards for the entire MOS community — influencing training pipelines, acquisition inputs, deployment doctrine, and the careers of every 5953 in the Marine Corps, whether or not they know your name.

At the senior enlisted level you operate across the MACS, the Marine Air Control Group, and the MOS community writ large. You advise commanding generals and wing staff on ATC radar system readiness, employment doctrine, and sustainment risk. You represent Marine Corps requirements in joint working groups on IFF interoperability standards, NTIA frequency management policy, and ATC radar acquisition programs. You identify and resolve systemic training deficiencies at MOS school level, coordinate with NAVAIR and PMA program offices on fleet-wide equipment issues, and develop the doctrine and tactics publications that govern how 5953s operate in every environment from garrison to combat. As 1stSgt or SgtMaj you carry the additional weight of every Marine in the unit — welfare, discipline, professional development, and the institutional culture of the section.

• 01Senior enlisted advisory at wing and MARFOR level, joint IFF interoperability working groups, acquisition program input and fleet-wide PQDR trend analysis, MOS school curriculum oversight, doctrine and TTP development, NTIA and DoD frequency policy representation, senior enlisted advisory and command climate ownership

• —FAAO 7110.65, COMNAVAIRFORINST, DoD IFF management publications, NTIA manual, JCIDS acquisition documentation, Marine Corps ATC doctrine publications, MCO P4790.2

• —MOS training pipeline produces field-ready 5953s, fleet-wide equipment readiness trends are improving or held at acceptable threshold, doctrine publications are current and tactically relevant, senior enlisted advisory is technically sound and operationally credible at every level of command

• —Losing the technical edge because you stopped doing the work — a senior 5953 who cannot speak credibly to current radar system faults and IFF interoperability issues loses the room fast. Letting acquisition programs proceed with requirements that do not reflect what Marines actually need in a MACS deployment, because you did not engage early enough.

A senior 5953 whose fingerprints are on the training syllabus, the doctrine publication, and the acquisition requirement — not just the retirement ceremony. The MOS is better because you were in it. Junior Marines who never met you are still working from standards you set.
