Field Artillery (FA) Weapons Locating Radar (WLR) Specialist

E-5 (Sergeant) · Army

E1–E3E-4E-5E-6E-7E8–E9
HEADS UP

As a section NCO you sign the pre-mission readiness report. When the counterfire grid goes out with an orientation error and the FA battalion FSO traces it back to your section, the 15-6 investigation starts with who signed that document. The technical discipline you held at E-4 is now your professional liability as a section sergeant. Own it.

The Honest MOS Read
Sergeant in a Target Acquisition platoon is a small, technically dense leadership seat. You run a Q-53 section — typically four to six soldiers — and you own everything from radar PMCS to section counterfire output to the monthly DA 4856 counseling on every soldier below you. The platoon sergeant runs the platoon; you run the section. That distinction sounds clear until you are in a field problem at 0300 with a generator fault, one operator off comms, and the FA battalion FSO asking the platoon commander why your section missed the last detection window. Orientation is the foundational technical discipline of the section NCO's job and it is unforgiving. The counterfire timeline — from enemy weapon firing to grid passed to the mission processing cell — is measured in seconds. If your section's orientation is off by any amount, every grid in that window is off by the same amount, and the cannon battery fires on bad data. You are the NCO who physically verifies the orientation stakes, reads the system's azimuth data against the survey team's handoff, and signs the readiness report. Not your senior operator, not the warrant officer. You. The moment you accept someone else's verbal confirmation without checking it yourself you have transferred your professional accountability to a habit that will eventually fail. The counseling cadence is the other thing most new section NCOs underestimate. Monthly DA 4856s on every soldier are not paperwork — they are the legal foundation of every adverse action you might ever need to take. The section NCO who cannot produce a counseling chain when the Article 15 hearing arrives has a problem the platoon sergeant cannot fix. Write the counseling in second person, with a Plan of Action that is specific and measurable, signed by the soldier before he leaves your vehicle. ATP 6-22.1 is the reference. Read it before your first counseling, not after the first problem. Your technical credibility with the section matters more at E-5 than at any previous rank. The soldiers below you are watching whether you can actually run the Q-53 or whether you are a supervisor who forgot the system. Stay current on the BIT sequence, the orientation procedure, and the unit-level TM troubleshooting trees. The warrant officer in the battalion runs a different technical depth conversation with you than with the operators; he expects you to know the fault codes and the operator-level fixes before calling him. The section NCO who knows the system and the section NCO who knows the paperwork are not the same soldier, and the TA platoon sergeant wants both in one person. ALC is the STEP gate for E-6 and it does not get easier to attend as the section gets busier. Build the packet while the section is not in a deployment cycle or a CTC train-up. The platoon sergeant needs to fight for the slot; give him something worth fighting for.
Career Arc
  • 01SGT pin-on — post-BLC, post-promotion-point cutoff, post-chain-recommendation.
  • 02Section NCO designation: assigned a Q-53 section with four to six soldiers — the first formal NCO leadership seat.
  • 03First monthly DA 4856 counseling cycle on section soldiers — cadence established from day one.
  • 04First major section training event as the section NCO: emplacement drill, orientation verification, live mission window — the TA platoon sergeant's read on section NCO quality.
  • 05ALC (Advanced Leader Course) slot competed — required for E-6 board; 31 academic days, the primary STEP gate.
  • 06First NCOER written for a soldier in the section (if section has a SPC approaching E-4 board or SGT approaching BLC).
  • 07131A FA Targeting Technician warrant officer path decision: apply now or defer to E-6.
Common Screwups
  • ×Counseling verbally instead of in writing. The section NCO who has no DA 4856 chain when the Article 15 hits does not have a position the platoon sergeant can defend. Write every counseling. Sign every counseling. Keep a copy.
  • ×DUI at SGT — promotion flag, demotion risk under AR 600-8-19, NCOER blast, and the scrutiny of the TA platoon sergeant and the HHB 1SG. The section loses its NCO for the duration of the investigation.
  • ×Integrity failure on a technical record — PMCS log, counterfire track log, orientation record — written after the fact or falsified to cover a missed maintenance window. The warrant officer reads these logs and the TA platoon sergeant does spot checks.
  • ×ACFT fail — section NCOs who fail the test they require their soldiers to pass lose the section's respect before the next formation. Four consecutive failures trigger separation proceedings under AR 635-200 regardless of rank.
  • ×OPSEC breach — one photo of the radar employment, one screenshot of the sector-of-search parameters shared outside classified channels. The brigade S2 investigates personally. The result is an Article 15 or worse, depending on what was shared and where.

A Day in the Life

  • 0530PT formation. At E-5 you run the section's PT plan — you set the work, you lead or designate a leader for each event, you track soldiers who are struggling on ACFT events. The section's aggregate ACFT score is visible to the platoon sergeant.
  • 0630–0700Shower, change, chow.
  • 0730Section accountability check — soldiers present, kit accounted for, any overnight issues reported up. If there is a soldier issue from the barracks it lands on your desk before 0900.
  • 0900Platoon formation. TA platoon sergeant confirms the day's training schedule. At E-5 you already know the schedule and you have already briefed the section on what they need to bring.
  • 0915–1130Section training block: emplacement drill, orientation verification procedure, STP 6-13R task sustainment runs with junior operators, or PMCS on the radar, shelter, and generator. You are supervising, correcting, and evaluating — not just performing.
  • 1130–1300Lunch. If there is a maintenance fault the section needs to resolve, you may keep the section through lunch in the motorpool with a break.
  • 1300–1600Afternoon block: counseling sessions (monthly DA 4856s are distributed across the month — you schedule one or two per week to avoid a monthly crunch), vehicle maintenance, comms procedures, or administrative work. On field-exercise days this is the execution window.
  • 1600–1700End-of-day formation. Section NCO accountability to the platoon sergeant: section status, any outstanding issues, anything that needs to go to the 1SG. If a soldier has a problem — medical, financial, family — this is the window you catch it.
  • EveningALC prep or personal time. At E-5 the ALC packet needs to be ready; some section NCOs work on it in the evenings rather than wait for administrative time that may not materialize before a field event.

Weekly Cadence

The week at E-5 is heavier administratively than anything at E-4. Monday is the training week kickoff — section status confirmed, PMCS schedule reviewed, training plan confirmed against the battalion calendar. Tuesday through Thursday carry the technical training weight: emplacement drills, operator task sustainment checks, counterfire procedure runs. Friday is motor stables, area cleanup, and the weekly counseling session if a soldier has one scheduled. The quarterly training cycle is the real rhythm. The QTB (Quarterly Training Brief) is where the platoon sergeant defends the platoon's training plan at battery level, and your section's readiness inputs drive that brief. If your radar system is red on the readiness report when the QTB slides are due, the platoon sergeant is defending a problem you created. Build your maintenance schedule four to six weeks out, bid your generator service time and radar calibration windows early, and tell the platoon sergeant about constraints before the QTB brief, not during it. When a CTC rotation or collective training exercise is on the calendar, the eight weeks before it are consumed by pre-deployment tasks: equipment inventories, PMCS completion, operator task sustainment qualification, PCC/PCI cadence establishment. During the rotation the section runs two-person shift rotations — senior operator and a qualified display operator — on twelve-hour windows. The section NCO is supervising, correcting in real time, and briefing the platoon commander on section output after each mission window. The OC/T is grading everything you do against the ARTEP-MTP task standard.

Key Skills — How to Drill Each

  1. 01
    Run the section through a complete emplacement-to-first-detection cycle — orientation survey, BIT sequence, sector-of-search assignment, mission-window open — at the ARTEP-MTP standard.
    Drill this sequence in garrison before the field problem, not during it. Walk the section through the emplacement in the training area behind the motorpool, time it, identify the steps where individual soldiers hesitate, and fix those steps in the next repetition. The ARTEP-MTP task standard for the TA platoon's collective counterfire tasks is the bar; the TA platoon sergeant and the OC/T grade you against it, not against whatever standard the previous section NCO set.
  2. 02
    Compute and validate orientation data — surveyed position, datum, equipment azimuth — and confirm the system lay is within tolerance before the mission window opens.
    The survey team hands you a document — a surveyed position and a known azimuth to a reference point. Read those numbers. Input them into the system. Check the system's computed orientation against what you computed manually from the survey data. If they disagree, stop and resolve the discrepancy before the window opens. This takes ten minutes. Accepting a marginal orientation because the window is about to start is how counterfire grids go wrong.
  3. 03
    Write a legally defensible DA 4856 counseling — specific Plan of Action, measurable standard, signed before the soldier leaves.
    Read ATP 6-22.1 before the first counseling. The critical piece is the Plan of Action: write it in second person ('You will report to PT formation at 0530 on the following dates'), name the deliverable, name the date, name the consequence for non-compliance, and get the soldier's signature before he walks out. The counseling that does not have a signed PO A is the counseling the SJA cannot use when the adverse action arrives.
  4. 04
    Brief the TA platoon commander on the section's counterfire output — tracks detected, classifications, grids passed, misses and their causes — in language the FA battalion FSO will use without rewording.
    The brief is not a recitation of the track log. It is an analysis: how many detections, how many grids passed in time, what missed and why (terrain mask, system fault, operator gap), and what you are doing to fix the misses. The FA battalion FSO briefs the battalion commander off the platoon commander's slide; your brief to the platoon commander is the input that drives that slide. Say what you found, say why it happened, say what you are doing about it.
  5. 05
    Manage the section's PMCS and maintenance schedule across the radar, shelter, generator, and vehicles — report the deadline status to the platoon sergeant honestly before the readiness report is due.
    The maintenance schedule is a calendar in your section's training plan. The generator has a TM-specified service interval; the radar has a scheduled calibration window; the vehicles have oil changes and tire checks. Build the schedule before the field problem train-up, not during it. If a fault comes up that puts the system on deadline, call the platoon sergeant and the warrant officer immediately. The section NCO who hides a maintenance fault from the platoon sergeant because he does not want to look like the red section is the section NCO the battalion S4 finds out about three weeks later.

Manuals & References — What Chapters Matter

  • FM 3-09 — Field Artillery Operations.
    At E-5 you own the counterfire output side of this document. Read the target acquisition and counterfire chapters completely; understand how the grids your section produces are processed by the mission processing cell, who releases the cannon battery, and what the timeline looks like from the enemy weapon's muzzle flash to the battery fire command. The section NCO who understands the full counterfire cycle debugs detection gaps better than the one who only knows his section's piece.
  • ATP 3-09.24 — Field Artillery Support of the Brigade Combat Team.
    This is the operational context for your section's work. The BCT fires cell and the FA battalion FSO interface with the TA platoon through the framework in this ATP. Understanding the fires coordination and the counterfire decision process at the BCT level tells you why the platoon sergeant cares about your section's detection rate in the terms he briefs it.
  • TM-series for the AN/TPQ-53 — operator and unit-level, including the unit-level troubleshooting trees.
    The warrant officer expects you to work through the operator-level troubleshooting trees before calling him. The unit-level TM tells you what the section can fix and what goes to higher maintenance. Know the line between operator-level and unit-level maintenance before a fault appears during a mission window.
  • AR 600-20 — Army Command Policy; ATP 6-22.1 — The Counseling Process; AR 623-3 — Evaluation Reporting System.
    These three documents are the legal foundation of your NCO authority. AR 600-20 defines the command relationship and the limits of your authority. ATP 6-22.1 tells you how to write a counseling that holds. AR 623-3 tells you how the NCOER system works — the ratings, the blocks, the rater and senior rater relationships. Read all three before your first NCOER input, not after.
  • TC 7-22.7 — The Army Noncommissioned Officer Guide; ADP 6-22 — Army Leadership and the Profession.
    TC 7-22.7 is what the BLC curriculum uses as the NCO leadership foundation. ADP 6-22 is the Army's doctrinal statement on what leadership means. At E-5 in a TA section the leadership reading translates directly: you are responsible for the professional development of the soldiers below you, and those two documents tell you what the Army expects that to look like.

Standards — How to Hit Each

  • BLC graduate — required for E-6 board; ALC packet ready when the SSG conversation enters the picture.
    BLC is the first step; ALC is the STEP gate for E-6. Build the ALC packet before the platoon sergeant asks. The ALC slot requires BLC completion, ALC eligibility by date of rank, and a clear flag status. The soldiers who get the early windows are the ones whose section NCOs did not have to spend time on the administrative preparation.
  • Section operational status at or above the TA platoon's METL standard — radar mission-ready percentage briefed at the platoon training meeting.
    The platoon sergeant briefs the FA HHB 1SG off each section's operational status. Your section's radar readiness percentage is your number. If it drops below the METL standard you need to know why — fault code, parts on order, maintenance window — and you need to have reported it honestly before the platoon sergeant found it on the readiness report.
  • Section certified at ARTEP-MTP 'T' rating on the collective counterfire tasks — emplacement, orientation, detection, reporting.
    The ARTEP-MTP collective task standard is the external bar the OC/T uses at a CTC rotation. In garrison, run your section through the task sequence against the standard in the task list, grade it honestly, and fix the gaps before the field problem. The 'T' rating requires every step performed to standard; the section that practices the short version in garrison fails the step it skipped in the field.
  • ACFT 560+ as the floor — section NCOs who fail the test they require their soldiers to pass lose section cohesion.
    Five sixty is above average for the FA enlisted force and signals that the section NCO is credible when he enforces PT standards. Train the events you are weakest on personally. The section watches whether the section NCO has a standard for himself that is lower than the one he holds them to.

Technical Mistakes — Concrete Consequences

  • Signing the pre-mission readiness report without physically verifying the orientation stakes and BIT status yourself — accepting the senior operator's verbal confirmation.
    When a counterfire grid leaves the section with an orientation error, the 15-6 investigation starts with who signed the readiness report. Your signature is your statement that the section was ready. If you did not check, your signature is a false statement. The platoon sergeant cannot protect you from that.
  • Counseling soldiers verbally and maintaining no DA 4856 chain.
    When the first adverse action arrives — Article 15, QMP flag, chapter action — the SJA asks to see the counseling record. 'I told him verbally' is not a record. The soldier's defense attorney knows this. Without a counseling chain the adverse action is harder to sustain and the platoon sergeant is defending a section NCO who did not do the administrative work.
  • Letting the generator maintenance window slide because the section is tasked for a detail or a competing mission.
    The generator fails during a mission window. The Q-53 drops off-air. The counterfire processing cell loses the picture. The FA battalion FSO asks the platoon commander why the section went dark during a detection window, and the maintenance log shows the service was overdue. Your name is on the maintenance schedule.
  • Running the section through a live mission window with an operator who is not sustainment-qualified on the display because the section is short-handed.
    An unqualified operator misclassifies a track — calls artillery as a bird or misses a mortar detection. The counterfire miss is attributed to your section in the track log review. The platoon sergeant asks why an unqualified operator was on the display, and the answer is your decision.

Career Decisions at This Rank

  • Apply to the 131A FA Targeting Technician warrant officer program at E-5 or wait.
    E-5 is the natural application window for the 131A. The selection board looks at GT score, ACFT, the chain's recommendation, and the depth of your 13R technical experience. A section NCO with a clean record, a strong section counterfire output, and a section NCO who has had the honest conversation with the battalion's 131A warrant officer is a competitive applicant. The warrant officer in your battalion will tell you directly whether you are a real candidate or whether your record needs work first. Start that conversation before the application window opens, not the week before the deadline.
  • Attend ALC early versus staying in the seat for another year.
    ALC is the STEP gate for E-6 and it is required for the promotion board. The soldiers who make E-6 early are the ones whose ALC is complete and whose NCOERs are clean before the promotion window opens. Attend ALC as soon as the platoon sergeant can get the slot. The argument for waiting — 'I want to run another CTC rotation first' — is understandable but the ALC slot is not guaranteed and the promotion window does not wait. Go when the window is offered.
  • Reenlist for a follow-on assignment versus ETS at the five- or six-year mark.
    At E-5 with a section NCO track record and an ALC completion date in sight, the reenlistment math is concrete. Pull the current HRC MILPER on the 13R SRB; the bonus structure for a Section NCO with a clean record and a deployed NCOER is a real number. The counterpart civilian path — defense contractor or federal GS position in a radar systems or fire control technical role — is accessible with a TS/SCI clearance and Q-53 operator background, but typically at the GS-09 to GS-11 entry level without the additional time in service that builds to a more senior civilian grade. The Army path to E-6 and a 131A warrant application is well-lit. Decide based on what you actually want, not based on what the retention NCO is authorized to offer.
  • Pursue a Master Gunner or advanced fires technical course versus line NCO schools.
    The FA branch does not have a formal Master Gunner credential for the 13R community in the way the armor branch has a Master Gunner Course for tankers, but the Master Fires Sergeant Course at Fort Sill is the senior FA NCO's technical credential. At E-5, the actionable school question is whether the platoon sergeant can get you a seat at any fires-specific advanced courses available through FIRES CoE at Fort Sill. Those schools build the technical depth that makes a 131A applicant credible and a future SSG TA platoon NCO worth the assignment.

How the Seat Varies by Unit Type

  • Active component FA HHB TA platoon (IBCT, SBCT, ABCT).
    The standard assignment. You run a Q-53 section in a TA platoon that supports the BCT's counterfire fight. CTC rotations are frequent, the training tempo is sustained, and the 131A warrant officer is present in the battalion and accessible for honest career advice. The section NCO competition at E-5 in this environment is real — promotion to SSG requires a clean NCOER record and ALC completion.
  • DIVARTY or corps-level TA battalion.
    At echelons above brigade the counterfire architecture is more complex — multiple BCTs, integration with joint fires and intelligence cells, higher-echelon counterfire priorities. As a section NCO the technical work is the same; the interface with the fires and intelligence chain above the BCT level is wider and more sophisticated. The section NCO in a DIVARTY TA battalion who understands the multi-BCT counterfire picture is developing expertise that translates well to a 131A warrant officer application.
  • Reserve Component FA battalion.
    One weekend per month and two weeks annual training. The sustainment qualification cadence for the section is compressed and the section NCO has to work harder to maintain operator task currency between drill weekends. If you are a traditional RC soldier at E-5, the ALC timeline and the promotion pathway are different from the active component. If you are AGR the pace looks more like active component. The radar mission is the same; the garrison rhythm is not.

What Good Looks Like at This Rank

The good 13R SGT runs a section the TA platoon sergeant sends to the hardest mission window without a backup plan. Not because the section NCO is impressive to watch, but because the section's output is reliable: the orientation is verified before every window, the track log is clean, the grids are formatted correctly the first time, and the PMCS log shows the system was maintained on schedule. The FA battalion FSO's counterfire detection slide names this section's rate in the upper group. Beyond the technical output, the good E-5 has a counseling chain on every soldier that the SJA could use tomorrow. Monthly DA 4856s, signed Plans of Action, measurable standards. When a soldier slides the section NCO has documentation that predates the problem by three months. The platoon sergeant does not have to explain why there is no paper trail. The good section NCO at E-5 is also building the next section NCO. The senior operator who gets BLC time and an honest pre-board counseling from the section NCO is more likely to be section-NCO-ready at E-5 than the operator who was just supervised. The section NCO who developed two SGTs the TA platoon sergeant can rely on is the section NCO the platoon sergeant recommends for ALC early. The career operates in both directions at once: the section performs today, and the section performs tomorrow without you. The ALC packet is already built. The 131A conversation has been on the calendar.

Preview — The Next Rank

At SSG you stop running one section and start running two or three. The TA platoon sergeant's job is to coordinate the platoon; your job at E-6 is to make sure the sections run without his hand on each one. The section NCOs below you are SGTs who are where you were twelve months ago — capable operators, new to the authority, uncertain about the counseling cadence. You are the senior NCO who turns that into reliable section performance at the platoon level. The NCOER writing load at SSG is real: two to three section NCO NCOERs per cycle, plus the relationship with the platoon commander who signs them. The NCOER that the senior rater can defend is the one with measurable outputs — detection rates, orientation-check pass rates, PMCS deadline percentages. If the section NCO you rated did not produce measurable output, that is a counseling problem that started months before the NCOER was due. SLC is the STEP gate for E-7. Build the packet while the platoon is not in a deployment cycle. The SSG who has ALC complete, a clean NCOER profile, and an SLC packet ready when the E-7 window opens is the SSG the TA platoon sergeant fights for. The SSG who is waiting for a slow week to build the packet is always waiting.
