Aviation Radar Repairer

E-6 (Staff Sergeant) · Marines

E1–E3E-4E-5E-6E-7E8–E9
HEADS UP

You are the radar shop chief. The RADHAZ safety program for the entire section is yours — not a checklist you hand to the Sgts, yours. The MALS QA officer's annual NAVOSH review of the avionics division starts with your documentation. The MALS maintenance officer briefs the CO on radar shop readiness rate weekly. The FitReps you write on your Sgts are the primary document the GySgt centralized board reads. Every system in the shop has your fingerprint on it. Manage accordingly.

The Honest MOS Read
Staff Sergeant in the 5948 community is the radar shop chief rank. The title means something precise: you are the senior enlisted technician accountable for the entire radar section's maintenance output, safety program, calibration currency, FitRep pipeline, and production posture. The section supervisors under you own their sections. You own the shop. The production meeting is the SSgt's formal accountability surface. The MALS weekly maintenance review — the meeting where the maintenance officer and the MALS QA officer review every work center's readiness rate, backlog, and quality metrics — is the meeting you brief. Not the section supervisors, not the GySgt. You. The data you present is the LRU queue status, the calibration program currency, the RADHAZ documentation status, and any open QA findings from the last inspection cycle. The maintenance officer reads you in that meeting: does this SSgt understand his own shop's numbers, can he brief succinctly under pressure, and does his status brief match the GCSS-MC queue data the maintenance officer already pulled. Those three things determine the maintenance officer's confidence in the radar shop without him having to walk through the avionics bay himself. RADHAZ safety program authority at SSgt is qualitatively different from anything below it. The Sgt section supervisor ran RADHAZ certification for his section. You run the RADHAZ program for the entire radar shop — annual surveys, exposure tracking, HAZMAT storage compliance, safety briefing documentation, incident reporting, and the occupational safety record the MALS safety officer and the NAVOSH inspector audit. When the COMNAVAIRLANT or COMNAVAIRPAC safety team visits the MALS for a command safety inspection, they brief the CO on the avionics division's RADHAZ posture. The SSgt radar shop chief is the Marine those findings trace back to. A deficiency in the RADHAZ program at the command safety inspection is not a paperwork embarrassment — it is a safety finding that can restrict radar maintenance operations until corrected, and the radar shop's FMC rate drops immediately when the section is standing down for corrective action. The FitRep pipeline for your Sgts is the SSgt's most consequential administrative product. At Sgt you wrote one to two Cpl Section A inputs per cycle. At SSgt you write three to four Sgt FitRep Section A narratives per cycle, the reporting senior builds attribute evaluations from your inputs for each, and the reviewing officer reads your inputs at the MALS FitRep board where relative value placement is assigned. The Sgt whose Section A narrative accurately describes observed performance in action-result-impact terms with specific outcomes is the Sgt the reporting senior can place in the upper relative value tier with confidence. The Sgt whose Section A narrative reads 'outstanding section supervisor who excels across all performance categories' is the Sgt the reporting senior revises, the MALS maintenance officer questions, and the reviewing officer places in the middle relative value tier by default. The SSgt who writes the former consistently, for three to four Sgts per cycle, is the SSgt whose own FitRep from the maintenance officer reflects the confidence earned. The MALS production meeting is the SSgt's external-facing briefing environment. Once per week the shop chiefs from each work center — avionics, airframes, power plants, radar — brief the MALS CO or the maintenance officer on the work center's status. The radar shop chief who walks into that meeting with a precise queue summary, a candid backlog assessment, and a specific recovery plan for any overdue LRUs is the shop chief the maintenance officer keeps in the seat for the next workup cycle. The shop chief who walks in with hedged numbers and defers every specific question to the section supervisors is the shop chief the maintenance officer assigns a GySgt observer to. Expeditions at SSgt operate at element-lead level. On MEU workups and deployments you are not just the senior 5948 at the expeditionary airfield element — in most cases you are running the element's technical maintenance mission, briefing the aviation combat element operations officer on radar section readiness, and making the fault-isolation disposition calls that determine whether a radar system is FMC, PMC, or NMC-M for the next launch cycle. The MALS CO knows your name before the MEU embarks because the MEU workup certification packages for the radar section went through you. The MEU SgtMaj watches your element's operational discipline in every exercise event and every port visit. The GySgt board prep window opens during the SSgt tour. The centralized GySgt selection board reads the FitRep package accumulated across the entire SSgt billet — the relative value placement, the Section A narratives the reporting senior wrote on you, and the PME record. SNCO Academy Career Course timing is the administrative gate you manage during the SSgt billet in the same way your Sgts managed Sergeants Course timing at their level. It is not optional. It is not something you manage around the maintenance calendar. The SSgt who is Career Course-complete before the GySgt board window is the SSgt who is competitive.
Career Arc
  • 01SSgt pin-on via centralized SNCO selection board under MCO 1400.32 — radar shop chief billet assumption in the MALS avionics division.
  • 02Shop-chief qualification confirmation — MALS maintenance officer and MALS CO read-in; full section ownership of RADHAZ program, calibration management, FitRep pipeline, and GCSS-MC labor accountability.
  • 03First MALS production meeting brief as shop chief — weekly maintenance review with the maintenance officer and QA officer; shop readiness rate, queue status, calibration program currency, open QA findings.
  • 04First MALS command inspection as radar shop chief — NAVOSH RADHAZ survey documentation, calibration program audit, workcard quality review; the result goes in your FitRep narrative.
  • 05MEU workup certification package completion — expeditionary element radar section certified for BLT manifest; section supervisors validated, ground-based radar systems (AN/TPQ-46/64, AN/TPS) mission-ready.
  • 06MEU deployment as expeditionary element lead — AN/TPQ-46/64 and AN/TPS section operations, battle-rhythm maintenance briefings to the aviation combat element operations officer.
  • 07SNCO Academy Career Course slot — schedule through the section chief (GySgt) 90 days before the course drop; required PME gate for GySgt board competitiveness.
  • 08GySgt centralized selection board window — FitRep relative value package read against every other SSgt in the MOS community; PME completion, FitRep quality, and section supervisory credibility are the drivers.
  • 09Billet decision point — NATTC instructor assignment, MARSOC or Recon support billet, NAVAIR contractor transition, or fleet continuation into GySgt MALS maintenance chief track.
Common Screwups
  • ×Missing SNCO Academy Career Course because the MEU workup, a deployment, or a maintenance surge consumed every available window without a documented recovery plan. The GySgt centralized board reads PME completion as a baseline; an SSgt who is not Career Course-complete when the board convenes is visibly disadvantaged regardless of FitRep quality. The MALS maintenance officer cannot waive the requirement. Manage the Career Course slot the same way you manage calibration due-dates — proactively, with a 90-day lead and a conflict plan documented before the conflict occurs.
  • ×NJP, DUI, or fraternization at SSgt. At shop chief rank, a UCMJ action removes the shop chief billet, triggers a Headquarters Marine Corps review of the SSgt's record for separation action, and forecloses the GySgt board in most circumstances. The Sgts in your shop are watching your off-duty conduct as closely as your on-duty performance. You set the standard for every NCO beneath you; violating it publicly is a leadership failure that survives the shop.
  • ×Writing inflated Section A narratives on Sgts — 'best section supervisor in the MALS, select now' without observable-behavior support — resulting in the reporting senior revising every input at the FitRep cycle and the MALS CO asking the maintenance officer why the radar shop chief's FitRep writing cannot stand without revision. At SSgt, inflated Section A inputs reflect directly on your professional judgment. The reviewing officer who sees a pattern of inflated, undefendable Section A inputs from one shop chief across multiple cycles does not write that shop chief a competitive GySgt board narrative.
  • ×Hiding a RADHAZ incident, a calibration-currency violation, or a GCSS-MC fraud-waste-abuse indicator from the MALS maintenance officer to protect the shop's record. The MALS QA officer and the NAVOSH inspector both have direct access to the documentation that the SSgt radar shop chief is responsible for maintaining. A covered incident surfaces in an audit; an honestly reported incident with a specific corrective action demonstrates the program integrity the MALS CO expects from a shop chief. The SSgt who buries an incident and gets caught loses the maintenance officer's trust permanently. The SSgt who reports it, fixes it, and briefs the corrective action earns a different kind of reputation.
  • ×Failing body composition or PFT/CFT standards while holding a shop chief billet. At SSgt, a fitness failure begins a remediation cycle under MCO 6100.13, triggers a MALS leadership notification, and is visible at the GySgt centralized board in the conduct and fitness record. The shop chief who cannot meet the physical standard while expecting his Sgts to meet it has lost the most basic form of credibility a senior NCO holds.

A Day in the Life

  • 0500Wake. Check the section group chat and the MALS maintenance status channel for overnight NMC-M aircraft — any radar-attributed discrepancy that hit the queue overnight means you know the priority before PT formation. If an APG-79 or APG-73 LRU went NMC-M and the section supervisor has not already texted you, he will by 0530.
  • 0530PT formation. You report to the MALS GySgt or the avionics division officer and give accountability for the radar shop. The shop chief who is the last NCO into the avionics division formation is setting a standard for his section supervisors. Report clean.
  • 0545–0700Unit PT. Run at the front of the shop's NCO section. On hump days you carry the weight the GySgt expects a shop chief to carry. The section supervisors are watching how you perform PT — they model the section's fitness culture on yours, not on your instructions.
  • 0700–0830Hygiene, chow, GCSS-MC pull. Before the morning brief: pull the radar shop's LRU queue status, the calibration due-date list, and the RADHAZ certification board. Identify any anomaly — an overdue calibration, an LRU that crossed into extended-dwell territory overnight, a RADHAZ cert that lapsed — before the section supervisors arrive. Any anomaly you brief the section supervisors on at the morning meeting is one the GySgt does not find during the MALS morning brief.
  • 0830Shop morning brief. You brief the section supervisors on the shop's priorities for the day: priority LRUs by aircraft-availability impact, calibration coordination items, any safety or QA items from the previous day. The section supervisors brief their sections. No Marine in the radar shop is asking the GySgt a question that belongs to you.
  • 0845–0900Shop safety walkthrough. Walk the avionics bay before full maintenance tempo begins — RADHAZ clearances posted for energized systems, lockout/tagout tags in place on de-energized systems, calibration stickers current on the test equipment the section supervisors assigned to this morning's bench work. The shop chief who finds a violation here catches it before the MALS safety officer does. The section supervisor who knows the shop chief walks the bay before 0900 maintains a different standard than the one who knows the shop chief only checks at the command inspection.
  • 0900–1130Primary work block. Supervision of section supervisors — you are not running a bench section, you are managing the shop's production against the daily queue priority. Walk through each section every 45 minutes: where are the priority LRUs in the diagnostic sequence, what decisions are the section supervisors facing, are there extended-dwell LRUs that need a beyond-I-level disposition call. Bring any complex disposition question to the MALS QA officer or the depot liaison yourself — do not send a section supervisor to a conversation you should be having.
  • 1100–1130MALS production meeting prep if Monday. Finalize the week's shop status brief — FMC rate from this morning's GCSS-MC pull, queue summary, calibration status, any open QA findings. The brief should be accurate as of this morning, not as of last Friday. You will deliver it in 90 seconds.
  • 1130–1300Chow. The shop chiefs eat with the avionics division NCO group. The GySgt is at the adjacent table. The conversations at chow are professional — the GySgt is noting which shop chiefs are talking production and which ones are on their phones.
  • 1300–1500Afternoon work block. GCSS-MC queue management, FitRep Section A drafts for Sgts whose cycle is due this quarter, monthly counseling sessions with each Sgt (SSgt board window review, Career Course scheduling status, FitRep relative value feedback, composite score gap review), calibration program forecast update, or RADHAZ program documentation review if the command inspection is within 60 days.
  • 1500–1600End-of-day close-out. Calibrated equipment accounted for by the section supervisors — you verify the report, you do not walk the tool crib yourself. GCSS-MC labor summaries reviewed for today's completed work before the section supervisors submit for SSgt authorization. Any LRU that crossed into extended-dwell status today gets a disposition conversation with the applicable section supervisor before final formation. Brief the GySgt on any administrative or maintenance items before formation.
  • 1600Final formation. GySgt or the avionics division officer gives the next day's plan. You brief your section supervisors: priority assignments for tomorrow, administrative items due this week, any liberty or OPSEC reminders. The section supervisors brief their sections. The radar shop should not be the section chiefs asking questions at the MALS formation that belong to their own shop chief.
  • 1630Liberty call on garrison days. Standard brief from you to the section supervisors before they leave: OPSEC (nothing about aircraft or radar systems on social media), DUI zero-tolerance, call you first if anything involving a Marine in the shop happens.
  • 1700–2100Personal time. SNCO Academy Career Course coursework if enrolled in the pre-course distance component. FitRep Section A drafts. GySgt board preparation — TFRS review, FitRep relative value self-assessment, MARADMIN pull for the 5948 GySgt board cycle. Defense contractor screening research if the pipeline decision is approaching. If a Marine in the shop has a financial, personal, or behavioral health problem, you are on the phone or driving there.
  • 2200Lights out. The shop starts at 0500 regardless of what the evening required.
  • MEU workup / expeditionary airfield element deploymentClock breaks. You are the senior 5948 at the expeditionary element — running the AN/TPQ-46/64 and AN/TPS radar sections, briefing the aviation combat element operations officer on radar system readiness at every launch cycle brief, managing RADHAZ compliance in an environment without the parent MALS's NAVOSH infrastructure. The section supervisors run their sections; you run the element's technical mission. The MEU SgtMaj watches the element's operational discipline in every exercise event. The MEU workup certification package had your name on it for a reason.

Weekly Cadence

Monday is the shop chief's planning and briefing day. The MALS production meeting runs on Monday; the avionics division status brief is due to the maintenance officer before 1100. The first 30 minutes of the workday are the shop status pull — GCSS-MC queue, calibration due-date forecast, RADHAZ cert board — and the brief preparation. The production meeting is 90 seconds of accurate data delivered with the shop chief's credibility behind it; the preparation is 30 minutes of knowing the numbers before the meeting opens. The rest of Monday is section supervisor planning coordination: which section is working which priority LRU, what the week's calibration coordination items are, and which Sgt has a FitRep cycle closing this month that needs a Section A draft by Thursday. Tuesday through Thursday is the maintenance execution window. The shop runs at full tempo — section supervisors managing their bench sections, shop chief monitoring extended-dwell LRUs and escalation decisions, calibration lab coordination on any items due in the current or next week. The shop chief's walkthrough of the avionics bay every 45 minutes during the work block is not a supervision exercise — it is a production read. The section supervisor who has a section running cleanly does not need the shop chief's input during the walkthrough; the section supervisor whose LRU queue has an extended-dwell item and no disposition conversation happening needs the shop chief's intervention at the bench, not at the end of week when the FMC rate drops. Wednesday afternoon is the informal mid-week quality check: GCSS-MC labor summaries reviewed, calibration board scanned, any anomaly in the documentation corrected before Thursday's close-out rather than after the Friday audit finds it. Friday is administrative close-out day. The week's GCSS-MC labor summaries are reviewed, the section supervisors submit their section reports, and the shop chief's authorization signature goes on the shop-level labor record. The calibration due-date forecast is updated for the next 30 days with any new lab coordination initiated. The monthly Sgt observation log entries for each section supervisor are drafted from the week's observations — one paragraph per Sgt, drafted during Friday's administrative window, not assembled from memory the week before the FitRep cycle closes. The shop chief who closes Friday's administrative cycle clean — labor record accurate, calibration forecast current, Sgt observation logs drafted, any open counseling entries for the week documented — is the shop chief the GySgt can trust to run the avionics division through the weekend without a check-in call.

Key Skills — How to Drill Each

  1. 01
    Run the MALS radar shop's RADHAZ safety program to OPNAVINST 5100.23 and NAVMC 3500.14 standards — annual surveys current, exposure tracking maintained, HAZMAT storage compliant, incident reporting documented — and brief it cold to the MALS safety officer without pulling notes.
    Build a personal RADHAZ program binder before the first annual NAVOSH review you own. The binder contains: the current RADHAZ survey date and the next scheduled survey date, the exposure tracking log for every tech qualified on each radar system, the most recent safety briefing documentation and the date of the next required briefing, the HAZMAT storage compliance checklist updated monthly, and the incident reporting log for any RADHAZ or high-voltage deviation in the last 12 months. Walk through the binder with the MALS safety officer in the first 60 days of the shop chief billet — not to get credit, but to get his read on what a satisfactory NAVOSH review looks like in this specific MALS command. When the COMNAVAIRLANT safety team visits, the binder is the documentation package you produce. The section supervisors manage their sections' RADHAZ certs; you manage the program. Those are different things.
  2. 02
    Brief the MALS weekly maintenance review — radar shop readiness rate, LRU queue status, backlog, calibration program currency, open QA findings — in 90 seconds or less, from the data you already own, without hedging every number with 'I need to check the board.'
    Pull the GCSS-MC queue and the calibration log every morning before the section supervisors arrive. Build your shop status brief daily — not for the weekly meeting, but as a daily discipline that makes the weekly brief a summary of six days of monitoring rather than a Friday scramble. The format: aircraft-impacting LRUs by status (FMC, PMC, NMC-S, NMC-M count), calibration certs due in the next 30 days with the lab turnaround scheduled or pending, any open QA findings with disposition date. Deliver it under 90 seconds in the production meeting. The maintenance officer is reading whether you know your own shop's numbers; the Sgts in the room are watching whether you represent the shop credibly under the CO's gaze. Both audiences matter.
  3. 03
    Write Section A FitRep narratives on three to four Sgts per cycle — observed-behavior, action-result-impact, specific outcomes — at the quality level the MALS FitRep board accepts without revision.
    Maintain a monthly Sgt observation log — one paragraph per Sgt per month, drafted the last Friday of each month from your direct observations during that month. The observation log is the raw material for every Section A you write. By the time the FitRep reporting period closes, you have 12 monthly observation entries per Sgt — specific events, specific outcomes, specific impacts on the radar shop's production or safety record. Section A writes itself from 12 months of documented observations; it does not write itself from memory and character impressions accumulated over a year. Submit the Section A draft to the reporting senior — the MALS maintenance officer or MALS CO — 21 days before the submission deadline. Not 5 days before. 21 days before. The reporting senior who receives a Section A draft with three weeks to review it experiences a different shop chief than the one who uploads it the morning it is due.
  4. 04
    Manage the radar shop's calibration program at the shop-chief level — due-date forecasting 60 days out, cal lab coordination, retroactive impact assessment when an out-of-cal finding occurs, corrective action documented before the QA officer asks.
    The calibration program at SSgt is not a certification board you check on Fridays. It is a maintenance program with dependencies that cascade through the workcard record. Build a 90-day calibration forecast spreadsheet — every piece of calibrated test equipment assigned to the radar shop, the last calibration date, the next due date, the calibration lab turnaround time, and the scheduled coordination date with the lab. Anything due in the next 60 days is already in coordination with the cal lab. When a piece of equipment goes out-of-cal unexpectedly, the first 30 minutes are: pull every workcard closed against that equipment in the expired period, document the affected LRUs, notify the MALS maintenance officer with a specific corrective action plan, and brief the QA officer before he asks. The SSgt who can produce a retroactive impact assessment within an hour of discovering an out-of-cal finding is the SSgt whose MALS CO sees a shop chief managing a program rather than reacting to one.
  5. 05
    Lead the expeditionary airfield element's radar section on MEU workup and deployment — emplacement, bore-sight, displacement, RADHAZ compliance in the field, and maintenance status briefings to the aviation combat element operations officer.
    The expeditionary element preparation begins 90 days before the MEU workup, not at embarkation. Schedule the AN/TPQ-46/64 and AN/TPS emplacement and displacement rehearsal with the section supervisors during the garrison calendar window. The drill sequence: section supervisor briefs the crew at the terrain model, crew executes without coaching from you, you AAR the timeline and the errors. Run it twice — once without time pressure, once under the MEU-SOC exercise clock. The section that has executed the emplacement sequence at least four times before the evaluator arrives does not slow down the battle rhythm at first light. For the operations officer brief: know the radar section's CASEVAC and MEDEVAC status, the RADHAZ exclusion zone coordinates at the emplaced position, and the system readiness timeline. The operations officer does not need the MIM explanation — he needs the system up on time and a clear answer to 'when is it FMC.'
  6. 06
    Develop your Sgts into SSgt-board-competitive Marines — FitRep-ready, Career Course-scheduled, composite score-tracked, and identified as shop-chief candidates by the GySgt before you rotate out.
    Run a monthly Sgt development review with each Sgt in your shop. The review covers: SSgt centralized board window timing, FitRep relative value feedback from the last cycle, PME completion status and Career Course scheduling, composite score components that are within the Sgt's control (rifle qualification, PFT/CFT, MCMAP belt, education credits), and any administrative gaps that would show up as weaknesses at the SSgt board. Document the review in the counseling file. The SSgt who can tell the MALS GySgt — before the GySgt asks — which of his Sgts are SSgt-board-ready this cycle, which are 12 months away, and what specific development actions are in work for each is the SSgt whose shop the GySgt trusts to run without daily oversight. That trust is the GySgt board narrative the maintenance officer writes.

Manuals & References — What Chapters Matter

  • NAVMC 3500.14 — Aviation Electronics Training and Readiness Manual (SSgt/shop-chief collective tasks and program responsibilities)
    At SSgt, your relationship with NAVMC 3500.14 shifts from section-level collective tasks to shop-level program responsibilities. Print the SSgt-level task list and the shop-chief program requirements and walk them with the MALS GySgt in the first 30 days. The collective tasks at shop chief level — RADHAZ program management, calibration program authority, FitRep pipeline management, GCSS-MC labor accountability — are the criteria the MALS command inspection evaluates the radar shop against. The MALS QA officer who walks into the avionics division for the command inspection is reading NAVMC 3500.14 task standards against the evidence in the shop documentation. The SSgt shop chief who knows the task standards at program-ID granularity runs the pre-inspection self-audit against those standards rather than against his own interpretation of what 'satisfactory' means.
  • OPNAVINST 5100.23 — Navy and Marine Corps Occupational Safety and Health (NAVOSH) Program
    This is the governing directive for the radar shop's RADHAZ program at every level — annual survey requirements, exposure tracking standards, HAZMAT storage requirements, incident reporting timelines, and the NAVOSH inspection criteria the COMNAVAIRLANT or COMNAVAIRPAC safety team uses during command safety visits. At SSgt you are responsible for the entire program, not just your section's certifications. Read the RADHAZ sections specifically: the annual survey frequency requirement, the exposure limit documentation format, and the corrective action documentation standards when an incident occurs. The SSgt who can cite OPNAVINST 5100.23 chapter and paragraph to the MALS safety officer during the NAVOSH review is the SSgt whose program documentation was built against the actual standard, not a general impression of what the standard requires.
  • MCO P4790.2C — Marine Corps Aviation Maintenance Program
    The radar shop's entire maintenance accountability program — workcard management, QA standards, GCSS-MC record requirements, calibration program authority, labor-hour accounting, beyond-I-level escalation packages — runs against the standards in this directive. At SSgt you are the last quality-assurance checkpoint before the MALS maintenance officer's signature. Chapter 6 (Quality Assurance), Chapter 10 (GCSS-MC maintenance records), and the labor-hour accountability chapter are the ones the MALS audit uses when it reviews the radar shop's production record. Know them at the level that allows you to run a pre-audit self-inspection of the shop's documentation and produce a specific corrective action plan for each gap found — not a general impression that everything looks fine.
  • MCO 1610.7 — Performance Evaluation System
    You write three to four Sgt FitReps per cycle, and the quality of those inputs determines the GySgt board competitive standing of the Marines in your shop. Read the current revision of MCO 1610.7 on Marines.mil before the first FitRep cycle you own as shop chief — the Section A narrative policy, the attribute marks rubric, the relative value placement mechanics, the reporting senior and reviewing officer responsibilities. The Section A input the SSgt writes is the foundation the reporting senior builds the attribute evaluations on. The MALS FitRep board's relative value placement uses the Section A inputs to differentiate Sgts whose observable performance diverges. An SSgt whose Section A inputs are consistently specific, defensible, and action-result-impact structured is building the GySgt board narrative that the reporting senior writes with confidence — from both the Sgts' records and his own.
  • MCO 1400.32 — Marine Corps Promotion Manual
    The SSgt-to-GySgt path runs through the centralized GySgt selection board — the same board mechanics as the SSgt board, but at a higher relative value threshold and with a deeper scrutiny of the FitRep package across the entire SSgt billet. Read the GySgt board mechanics chapter carefully: what the board reads, how the FitRep relative value package is assessed across multiple reporting seniors, what PME completion contributes at the GySgt level, and how billet diversity factors into the board's competitive read. Pull the current MARADMIN for the 5948 GySgt board cycle before the career conversation with the GySgt. The SSgt who understands the GySgt board mechanics is building his FitRep profile deliberately across the shop chief billet — not hoping that the good cycles stack into a competitive record.
  • MCO 1000.9 — Marine Corps Lateral Move and Reenlistment Program
    The B-billet and lateral-move pipeline decisions arrive during the SSgt billet — NATTC instructor assignment, MARSOC support billet, Recruiting Station assignment, MSG program. MCO 1000.9 governs the mechanics of the lateral-move contract, the SRB calculation for 5948 SSgts at reenlistment, and the billet-selection process for special duty assignments. Know the current SRB tier for 5948 SSgts before the career planner conversation. The SSgt who arrives at that conversation already knowing the SRB math, the billet options available, and the board criteria for each special duty assignment is having a productive career planning session — not a discovery meeting.
  • MCO 6100.13 — Marine Corps Physical Fitness, Body Composition, and Military Appearance Program
    At SSgt, the physical fitness standard is a shop-chief leadership signal, not a personal compliance requirement. The radar shop's average PFT and CFT scores are tracked in the MALS health-of-the-force report; the MALS CO sees the work-center-level averages. A shop chief who scores 1st-Class while his Sgts and junior techs score 2nd-Class across the board has a fitness culture problem that the GySgt will surface at the next MALS leadership review. The MCO 6100.13 remediation program for body-composition failures requires MALS-level leadership notification — a shop chief who triggers the remediation cycle is in the maintenance officer's weekly brief for the wrong reason.

Standards — How to Hit Each

  • SNCO Academy Career Course graduate — required PME gate for the GySgt centralized board; in-residence is the standard.
    Schedule the in-residence Career Course slot through the MALS GySgt 90 days before the course drop date. The Career Course is delivered at the Marine Corps University at Quantico in-residence or through the CDET non-resident equivalent; in-residence is the materially better option and the standard the GySgt board expects. When the MEU workup or a deployment maintenance surge threatens to consume the in-residence window, go to the GySgt immediately with a specific conflict and the next available course date — not 30 days before the course when nothing can be done. The SSgt who has not had the Career Course conversation with the GySgt before the SSgt board result even arrives is behind the timeline the GySgt expects a shop chief to manage. Do not manage it like a junior Marine manages Corporals Course. Manage it like the senior NCO the board is evaluating.
  • Radar shop RADHAZ program rated satisfactory or better at every MALS command inspection and NAVOSH review during the SSgt billet — one adverse finding in the RADHAZ program traces to the shop chief's name.
    Run a formal self-inspection of the radar shop's RADHAZ program documentation 45 days before every scheduled MALS command inspection. The self-inspection is not a walk-through — it is a documentation audit against OPNAVINST 5100.23 and NAVMC 3500.14 task standards, with every gap written down, a specific corrective action assigned, and a completion date tracked. The section supervisors run their sections' cert boards; you audit the program-level documentation they are maintaining. Brief the GySgt on the self-inspection results and the corrective action status 30 days before the inspection. The GySgt who hears about a RADHAZ program gap from the QA officer before hearing about it from the shop chief is not briefed by the shop chief the following week — he is briefed by the MALS maintenance officer.
  • MALS radar shop FMC rate at or above the COMNAVAIRFOR minimum threshold through maintenance production cycles — the MALS CO's FitRep narrative on you is correlated with this number.
    The FMC rate is the product of the entire shop's maintenance execution — queue management, calibration currency, QA documentation quality, section supervisor development — not just your personal bench work. Own the number. Pull the radar section's FMC rate from the GCSS-MC maintenance database daily and brief it at the production meeting without being asked for it. When the FMC rate drops below the threshold, identify the specific driver — a long-dwell NMC-M LRU, a calibration-caused workcard stoppage, a section supervisor qualification gap on a complex fault-isolation procedure — and bring a specific recovery plan to the maintenance officer in the same breath as the number. The MALS CO's FitRep narrative on the SSgt radar shop chief is shaped more by how the shop performs under pressure than by how it performs at steady state.
  • FitRep Section A inputs on three to four Sgts per cycle accepted by the reporting senior without revision — the reviewing officer should not be revising Section A language that the reporting senior already accepted.
    Build the Section A draft from the monthly Sgt observation log entries you have been maintaining throughout the reporting period. Submit the Section A draft to the reporting senior with a minimum of 21 days before the submission deadline. When the reporting senior requests a revision — language clarification, additional specificity, relative value adjustment — respond within 48 hours with the revised draft and a brief explanation of the specific observation that supports the language. The SSgt whose Section A inputs are consistently accepted without revision by the reporting senior and the reviewing officer is the SSgt whose own GySgt board narrative reflects that trust. The Section A revision request is not a paperwork problem — it is evidence the Section A was written without sufficient observation documentation behind it.
  • 1st-Class PFT and CFT under MCO 6100.13; the MALS health-of-the-force report shows the radar shop's average against the division average, and the GySgt sees both.
    Train the CFT events specifically alongside the section supervisors — the ammo-can lift and maneuver-under-fire sequence are directly analogous to the physical demands of the expeditionary airfield element the shop deploys to. The SSgt shop chief who trains with the Sgts and scores 1st-Class is the shop chief whose Sgts have a direct physical performance model to measure against. The one who scores 2nd-Class while expecting 1st-Class from his section supervisors has already undermined the expectation. Build the section's fitness culture deliberately — the shop's average PFT score at the next health-of-the-force review is a function of the standard the shop chief set in the 12 months before it.

Technical Mistakes — Concrete Consequences

  • Allowing a section supervisor to sign GCSS-MC labor summaries without auditing the entries, and countersigning the shop-level authorization without checking the section-level audit.
    At SSgt, your signature on the GCSS-MC shop-level labor authorization is the institutional endorsement that the section supervisors' entries were accurate and that the data going to the MALS production record is clean. When the MALS financial audit surfaces inflated labor hours in the radar shop, the investigation chain starts at the shop-level authorization signature — yours — and works down. A pattern of inflated hours across two or three sections generates a fraud-waste-abuse finding that goes to the MALS CO's desk and the Naval Inspector General's awareness. The SSgt who audits section labor summaries before signing and catches entry errors proactively is the SSgt whose MALS audit record is clean. The one who countersigns without checking is exposed to the full finding.
  • Deferring the RADHAZ survey past the required interval because the MEU workup schedule made scheduling difficult.
    The annual RADHAZ survey requirement under OPNAVINST 5100.23 does not defer for workup cycles. A survey that is overdue when the COMNAVAIRLANT safety team arrives is an immediate adverse finding that can restrict radar maintenance operations until the survey is completed and the results are reviewed. The radar section stands down; the aircraft maintenance schedule absorbs the readiness impact; the MALS CO briefs the finding at the type wing safety board. The SSgt radar shop chief who allowed the survey to lapse is the SSgt whose name appears in the safety board's finding. Schedule the annual survey in the first month of the shop chief billet and put it on the MALS training calendar as a hard event — not a tentative scheduling placeholder.
  • Failing to document an adverse counseling entry within 24 hours for a Sgt whose performance, conduct, or safety violation required the entry.
    When a Sgt in the shop files an appeal against a QA finding attribution, a UCMJ action, or an adverse FitRep, the investigating officer's first request is the counseling file. A verbal counseling that is not documented is invisible to the investigation and works against the shop chief, not the Sgt. The MALS maintenance officer cannot defend a shop chief who counseled verbally, allowed the performance problem to compound across a quarter, and then generated an adverse FitRep with no counseling paper trail supporting the Section A narrative. A page-11 entry written within 24 hours of the adverse event is five minutes of administrative work and a year of legal protection. Write it within 24 hours, every time, without exception.
  • Letting a beyond-I-level escalation package sit incomplete in the GCSS-MC queue because the section supervisor was waiting for additional fault-isolation data that was never going to close the diagnosis at I-level.
    An LRU that sits in NMC-M status at I-level beyond the expected diagnostic window is generating aircraft availability loss that appears in the FMC rate the MALS CO tracks. The section supervisor who has been working the same fault-isolation tree for three weeks without a disposition decision is a section supervisor who needed the shop chief's intervention at week one. The SSgt who lets the NMC-M dwell extend because the section supervisor is reluctant to declare the fault beyond I-level capability is the SSgt whose shop chief brief to the maintenance officer includes an uncomfortable explanation for why an LRU has been in the queue longer than the standard. Review the extended-dwell LRUs daily. When the diagnostic data indicates beyond-I-level, write the escalation package and send it. That is a legitimate, correct maintenance outcome.
  • Processing the NATTC instructor billet or the defense contractor pipeline inquiry without informing the GySgt first, creating the appearance that the shop chief is managing a parallel career exit while holding the shop chief billet.
    The MALS GySgt's trust in the shop chief is partially premised on the shop chief's commitment to the shop's current production mission. A shop chief who is conducting NATTC instructor interviews or defense contractor screening calls without the GySgt's awareness creates a leadership trust problem the GySgt discovers when the contact shows up in the unit's administrative queue or through informal network awareness. The conversation with the GySgt about career transition options is not a weakness — it is how every professional manages the pipeline honestly. Have it directly, early, and before anyone else in the chain has reason to surface it.

Career Decisions at This Rank

  • NATTC instructor billet — Pensacola or instructor assignment at the applicable training pipeline
    The NATTC (Naval Air Technical Training Center) instructor billet at Pensacola, or the applicable radar maintenance training pipeline, is the natural technical-depth extension for an SSgt 5948 who wants to spend time building the next generation of radar technicians. The instructor billet identifier at the GySgt board is a documented professional credential — it signals technical mastery and a willingness to invest in community development rather than personal advancement alone. The practical reality: instructor billets run 2-to-3 years, the pace is more predictable than the fleet MALS, and the work of building a junior tech's diagnostic reasoning from scratch is genuinely different from managing a production shop. The cost: departure from the fleet MALS network and the production-environment credibility that the GySgt board reads in fleet-tour FitReps. The SSgt who is drawn to the instructor role should pursue it with deliberate intent, not as a rest stop from fleet tempo. An SSgt who is not genuinely committed to the instructor mission will have a forgettable billet record that neither the instructor cadre nor the GySgt board remembers favorably.
  • Raytheon, Northrop Grumman, or L3Harris defense contractor pipeline — when to start, how to build the credential, and what the honest post-service math looks like
    The defense contractor market for I-level radar maintenance technicians is real and remunerative. Raytheon (AN/APG-79 and AN/APG-81 systems), Northrop Grumman (AN/APG-81 F-35 radar systems), and L3Harris (ground-based radar and EW systems) actively recruit experienced 5948 SSgts and GySgts for field service representative, depot maintenance, and program management roles. The honest timing question is when the transition makes sense financially and professionally — not whether it exists. The SSgt who EASs at the first opportunity for the contractor salary leaves the GySgt board, the master tech credential, and the instructor billet identifier on the table. The SSgt who finishes the shop chief billet, completes the Career Course, makes GySgt, and then transitions carries a credential the contractor market pays a premium for. Pull the current Glassdoor and LinkedIn FSR salary data for the specific systems you are qualified on, do the retirement math for a full 20-year timeline, and have the conversation with a GySgt who transitioned recently before you decide. Do not make the decision based on one contractor contact who happened to reach out during a port visit.
  • FAA radar technician civilian track — FCC General Radiotelephone Operator License (GROL) and the FAA Air Traffic Organization maintenance pipeline
    The FAA Air Traffic Organization employs radar maintenance technicians (Electronics Technicians under the AT series) at Terminal Radar Approach Control facilities and en-route centers nationwide. The 5948 SSgt's I-level radar maintenance background is directly applicable to ASR-11 and other ATC radar systems. The credential pathway is the FCC General Radiotelephone Operator License (GROL) — a federally administered exam available through testing centers and prep-coursework via the ARRL and commercial prep providers. The GROL satisfies FAA hiring requirements for the electronics technician pipeline; the 5948 background satisfies the system experience requirement that most GROL holders without a military maintenance background cannot match. The honest math: the FAA AT electronics technician career offers competitive federal-employee benefits, geographic mobility across the national airspace system, and a technically engaging environment without the operational tempo of the fleet. Start GROL prep coursework as early as the SSgt billet if the FAA track is a genuine interest — the exam is civilian-accessible and not dependent on any transition timeline.
  • GySgt board competitiveness — FitRep package building, billet diversity, and the troop-leading versus occupational SME track decision
    The GySgt centralized board reads the SSgt's entire FitRep package across the shop chief billet — relative value placement, Section A narrative quality, reporting senior's confidence signal, PME completion (Career Course), and billet diversity. The honest preparation question is whether the SSgt's current FitRep trajectory is producing the relative value placement that makes him competitive, not whether he knows the technical content of the 5948 MOS. Ask the MALS GySgt directly after every FitRep cycle closes: 'Where did I land in the relative value ranking this cycle?' The GySgt knows. The SSgt who knows his own FitRep relative value position after each cycle can calibrate the next cycle's Section A quality, billet focus, and reporting-senior relationship accordingly. The troop-leading track (1stSgt, SgtMaj) and the occupational SME track (MALS maintenance chief, NAVAIR technical billet, schoolhouse master tech billet) diverge meaningfully at the GySgt level — and the SSgt who has not had the explicit conversation with the GySgt about which track he is building toward before the GySgt board approaches is making the board's read harder, not easier.
  • SNCO Academy Career Course in-residence versus CDET non-resident completion
    In-residence Career Course at Marine Corps University, Quantico, is the standard and the materially better option — the peer network of SSgts from across the Marine Corps, the residential curriculum depth, and the formal leadership practicum that CDET cannot replicate are worth the temporary absence from the shop. CDET non-resident satisfies the PME completion requirement for the GySgt board when in-residence is genuinely unavailable due to deployment or workup — but it is the fallback, not the preferred path. The SSgt who uses CDET because scheduling was inconvenient is making a credential decision that the Career Course cadre, the MALS GySgt, and the GySgt board can distinguish from the SSgt who used CDET because the MEU calendar made in-residence impossible and documented the conflict before embarking. One of those SSgts is managed by his calendar; the other managed his calendar. The GySgt board reads both records and knows the difference.

How the Seat Varies by Unit Type

  • Active component MALS at CONUS MCAS — F/A-18 supporting units (Beaufort, Miramar, Cherry Point)
    The standard 5948 SSgt radar shop chief assignment. The MALS has a mature avionics organization with multiple senior 5948s, an established QA culture, and a workload driven by the Hornet and Super Hornet flight schedule and the MEU workup cycle. The radar shop at a large CONUS MALS runs three to four section supervisors under the shop chief and produces a predictable maintenance tempo with high-intensity surges during pre-deployment pushes. The GySgt mentorship is available and active because the senior 5948 community is present in the shop in numbers. The SSgt who performs well as a shop chief at Beaufort or Miramar has a FitRep narrative the GySgt board can contextualize against known standards.
  • Active component MALS at CONUS MCAS — F-35B supporting units (Beaufort, Yuma)
    The AN/APG-81 AESA radar maintenance environment is more technically dynamic — frequent MIM updates, Northrop Grumman field service representatives present in the shop with a contractual maintenance relationship, and depot-coordination procedures that are more complex than the legacy APG-73/79 I-level model. The SSgt shop chief at an F-35B MALS is managing a contractor interface relationship in addition to the organic section supervisors, and the MALS CO is under more scrutiny on F-35B readiness rates from the type wing commander level. The technical credential earned at an F-35B MALS is commensurately stronger — both for the GySgt board and for the defense contractor transition market.
  • Forward deployed MALS at MCAS Iwakuni — III MEF
    The operational tempo at Iwakuni is MEF-forward: partner-nation exercises with Japan Air Self-Defense Force and Korean Marine Corps, a contingency response posture during Indo-Pacific crisis periods, and a maintenance mission that supports the forward-deployed Marine Aircraft Group squadrons at a pace that CONUS units replicate only during workups. The SSgt radar shop chief at Iwakuni carries per-capita responsibility for more of the avionics division's senior leadership than a CONUS shop chief of equivalent rank — fewer GySgts in the chain, more direct exposure to the MALS CO's visibility. Unaccompanied for most SSgts; verify current policy with the GySgt. The FitRep narrative from a III MEF forward SSgt shop chief billet is a different document than the narrative from a CONUS shop chief billet, and the GySgt board reads the operational context.
  • MEU BLT expeditionary element — SSgt as radar element lead
    The radar element lead on the BLT's expeditionary airfield element is the SSgt's primary operational deployment role. The element operates AN/TPQ-46/64 and AN/TPS ground-based radar systems at the combat operations center in support of the MEU's operational mission. The parent MALS's QA infrastructure, calibration lab, and NAVOSH officer are not present — the SSgt is managing RADHAZ compliance, calibration currency (coordinated through the ship's communications to shore-based labs), and maintenance disposition decisions in an uncontrolled operational environment. The aviation combat element operations officer briefs the MEU CO on radar section readiness; the SSgt element lead is the source of that readiness data. A clean MEU deployment as radar element lead is a formative shop-chief credential — the FitRep narrative the MALS CO writes from a MEU deployment reads differently than a garrison-only narrative.
  • Reserve component MALS
    Reserve 5948 SSgt radar shop chiefs face the compressed qualification and evaluation timeline characteristic of all reserve aviation maintenance billets. Monthly drill weekends plus annual training provide a fraction of the active-component annual qualification hours. Reserve shop chiefs who are competitive for the GySgt centralized board typically pursue active-duty training (ADT) orders during key FitRep periods to supplement the annual training qualification record. The command inspection at AT is the reserve radar shop's primary formal evaluation event — it carries T&R tracking weight against the same NAVMC 3500.14 standards as the active-component command inspection, in a compressed AT window. The GySgt centralized board processes reserve and active component records through the same mechanism; FitRep relative value comparison at the board includes both, and the board reads the operational context of each record.

What Good Looks Like at This Rank

The good 5948 SSgt radar shop chief is the marine the MALS maintenance officer puts on the weekly production brief without a rehearsal. He walks into the maintenance officer's conference room on Monday morning with the radar section's FMC rate from this morning's GCSS-MC pull, the LRU queue status by category, the calibration due-dates for the next 30 days with the lab coordination status on each, and any open QA findings with the specific corrective action and disposition date. He delivers it in 90 seconds. The maintenance officer has already seen the GCSS-MC data before the meeting — what he is reading is whether the shop chief's brief matches the data and whether the shop chief understands the implications. When the FMC rate dropped two points last week, the maintenance officer wants to hear 'we have an NMC-M APG-79 transmitter that has been in diagnostic work for nine days; the section supervisor is declaring it beyond-I-level today and the escalation package goes to the depot by end of week.' Not 'I need to check with the section supervisors on that.' His Sgts are SSgt-board-competitive because he ran a monthly development review with each one, documented the conversation, tracked the composite variables, identified the gap, and built a specific 90-day action plan. The three Sgts who compete at the SSgt centralized board during his shop chief tour do so because the shop chief identified the board window 12 months out and built the FitRep profile, the Career Course slot, and the qualification record with them — not from memory and character impression at the last minute, but from 12 months of monthly observation log entries that produced Section A narratives the MALS FitRep board accepted without revision. The GySgt tells the MALS maintenance officer that the radar shop chief is why those Sgts are SSgt-competitive. The MALS CO's FitRep narrative on the SSgt reflects what the GySgt told the maintenance officer. The RADHAZ program documentation is clean because the shop chief built a program binder in the first 30 days of the billet, runs a 45-day self-inspection before every command inspection, and has never had a deficiency finding trace to the radar shop on his watch. The COMNAVAIRPAC safety team that visited the MALS 14 months into his billet found a satisfactory RADHAZ program in the avionics division and noted the shop chief's documentation management specifically in the post-inspection debrief. The MALS CO quoted the debrief in the SSgt's FitRep narrative. The GySgt board reads it in the reviewing officer's block.

Preview — The Next Rank

GySgt is the senior SNCO technical authority for the MALS avionics division or the equivalent senior maintenance leadership billet. The transition from radar shop chief to GySgt is the transition from owning one shop's production and FitRep pipeline to owning the entire avionics division's enlisted leadership — multiple shop chiefs, six to eight Sgt FitReps per cycle, the division's collective T&R readiness rate, and the MALS CO's maintenance briefing at the wing commander level. The shop chief was accountable to the MALS maintenance officer. The GySgt avionics chief is accountable to the MALS CO. The FitRep load at GySgt is the piece the shop chief billet does not fully prepare you for in scale. At SSgt you wrote three to four Section A inputs per cycle. At GySgt you write multiple shop chief Section A inputs and the SSgt collective readiness narrative that the MALS CO reviews at the FitRep board. The relative value placement decisions at GySgt have direct SSgt-to-GySgt board implications that compound across multiple shop chiefs' careers simultaneously — one cycle where the GySgt's Section A inputs are inflated moves three shop chiefs' promotion timelines by years. The GySgt who writes clean, defensible Section A inputs for every shop chief in the division for three to four years is the GySgt the MALS CO trusts to run the division independently. The career fork at GySgt is the explicit one. The troop-leading track — 1stSgt, eventually SgtMaj — requires demonstrated leadership of a Marine Corps formation beyond the maintenance shop: company-level formation responsibility, FitRep discipline across a diverse Marine population, and the willingness to step away from technical authority toward people authority. The occupational SME track — MALS maintenance chief, NAVAIR technical liaison billet, schoolhouse master technician billet, senior enlisted advisor to a program office — keeps you in the technical domain at its highest level. The GySgt who has not made this choice explicitly before the MALS SgtMaj asks about it is not making a career decision — he is having a career decision made for him based on which billet opened first. Make the choice deliberately, on your terms, before the SgtMaj's conversation starts.
FAQ

5948 E6 — Frequently Asked Questions

Q01What does a E6 5948 (Aviation Radar Repairer) actually do?
You run the MALS radar shop's enlisted side — training, evaluations, schools, certifications, GCSS-MC records integrity, HAZMAT compliance, RADHAZ program currency, and the maintenance schedule that keeps the MALS mission-capable rate above the COMNAVAIRFOR minimum.
Q02What's the most important thing to know as a E6 5948?
You are the radar shop chief.
Q03What does a typical day look like for a E6 5948?
Time-blocked day at the E6 5948 rank tier: 0500 Wake. Check the section group chat and the MALS maintenance status channel for overnight NMC-M aircraft — any radar-attributed discrepancy that hit the queue overnight means you know the priority before PT formation. If an APG-79 or APG-73 LRU went NMC-M and the section supervisor has not already texted you, he will by 0530, 0530 PT formation. You report to the MALS GySgt or the avionics division officer and give accountability for the radar shop.…
Q04What mistakes get E6 5948 soldiers fired or relieved?
Missing SNCO Academy Career Course because the MEU workup, a deployment, or a maintenance surge consumed every available window without a documented recovery plan. The GySgt centralized board reads PME completion as a baseline; an SSgt who is not Career Course-complete when the board convenes is visibly disadvantaged regardless of FitRep quality. The MALS maintenance officer cannot waive the requirement. Manage the Career Course slot the same way you manage calibration due-dates — proactively,…
Q05What career decisions matter most at the E6 5948 rank tier?
NATTC instructor billet — Pensacola or instructor assignment at the applicable training pipeline — The NATTC (Naval Air Technical Training Center) instructor billet at Pensacola, or the applicable radar maintenance training pipeline, is the natural technical-depth extension for an SSgt 5948 who wants to spend time building the next generation of radar technicians. The instructor billet identifier at the GySgt board is a documented professional credential — it signals technical mastery and a willingness to invest in community development rather than personal advancement alone.…
Q06What's next after E6 for a 5948 (Aviation Radar Repairer) in the Marines?
GySgt is the senior SNCO technical authority for the MALS avionics division or the equivalent senior maintenance leadership billet.
Q07What manuals and regulations does a E6 5948 need to know cold?
NAVMC 3500.14 — Aviation Electronics T&R Manual (SSgt-level collective tasks and shop-chief responsibilities; you are evaluated against this at every command inspection).; MCO P4790.2C — Marine Corps Aviation Maintenance Program (the MALS maintenance program you now administer, not just execute; QA compliance traces back to you).; OPNAVINST 5100.23 — NAVOSH Program (RADHAZ safety survey requirements and high-voltage program administration standards you own at the SSgt level).
