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

E-6 (Staff Sergeant) · Army

E1–E3E-4E-5E-6E-7E8–E9
HEADS UP

At SSG you stop running one radar section and start running two or three. The counterfire output the FA battalion FSO briefs to the battalion commander every week is the sum of your sections' detection rates, orientation records, and report formatting. One section's sloppy orientation check does not stay in that section — it lands on your NCOER. Own every section's technical discipline the same way you owned your own when you were a SGT.

The Honest MOS Read
TA platoon SSB is a different job than section NCO in a way that most SSGs underestimate until they are six months into it. As a SGT you ran one Q-53 section. You knew every soldier by their ACFT score and their weakest operator task. You could physically verify the orientation stakes yourself before every mission window. Now you have two or three sections, each with its own section NCO, its own radar, its own generator schedule, and its own collection of operator certification gaps. You cannot physically touch every orientation check. You have to build section NCOs who are as disciplined about the check as you were — and that is a completely different skill than being disciplined yourself. The counterfire readiness brief at the FA HHB Quarterly Training Brief is the first place the battalion sees your work. You are defending your platoon's radar operational status percentages, your section NCOs' NCOER inputs, your platoon's detection rate at the last collective training event, and your ability to field sections at the survey team's survey pace. The FA battalion FSO has an opinion about all of this. He has been watching your platoon's detection rate across the last several exercises and he knows which sections are reliable and which are not. Your job is to close the gap between the reliable sections and the unreliable ones before the next CTC rotation, not after. The NCOER writing load is the thing most new SSGs are not ready for. Three to four per cycle. Each one requires you to capture measurable outputs from the section NCO's work over a twelve-month rating period. The section NCO who had a clean orientation record and a solid detection rate at the CTC rotation gets bullets that say so in concrete terms. The section NCO who let his PMCS slip and whose section went deadline during a live exercise gets bullets that say that — and a counseling chain that predates the NCOER by three months. The NCOER that inflates a section NCO who underperformed creates a false record the senior rater will eventually contradict, and the SSG who inflated becomes someone the FA branch senior NCO chain does not trust. You are also the senior NCO managing the interface between your platoon and the fires chain above it. The FA battalion FSO, the BCT fires cell, the supported maneuver brigade's intelligence cell — they all want counterfire data, and they all have opinions about the sector-of-search parameters and emplacement geometry the TA platoon is running. Some of those opinions are right. Some of them are tactically sound but logistically impossible given your section's survey timeline. Your job is to translate the fires cell's priorities into emplacement plans the section NCOs can actually execute — and to push back honestly, with specific reasoning, when the prioritized sector of search puts your sections in terrain that degrades detection performance. The FA battalion FSO respects a platoon SSB who comes to that conversation with ATP 3-09.24 knowledge and counterfire geometry. He does not respect one who says yes to everything and delivers a degraded picture. SLC is the STEP gate for E-7 and the packet does not build itself. The SLC window comes up against a deployment cycle, a CTC rotation train-up, and the continuous noise of running a multi-section platoon. The SSG who does not start building the packet when the platoon is in a garrison lull is the SSG who misses the early windows. The MLC packet starts the moment the SLC is complete. The FA branch's senior NCO career is built in two-year windows; the SSG who treats each window as an administrative chore instead of a career investment is the SSG who is still a SSB at fourteen years of service. And the 131A FA Targeting Technician warrant officer pipeline is your responsibility at this rank. Not just to encourage it vaguely — to run the conversation honestly. You have section NCOs and senior operators who are ready to apply and some who think they are ready but whose record is not competitive yet. The difference between those two populations is a section NCO who had an honest SSG telling him what the 131A warrant officer in the battalion actually looks for, versus a SSG who said 'yeah, you should look into that' and moved on.
Career Arc
  • 01SSG pin-on — post-ALC, post-promotion-board, post-chain-recommendation; time-in-grade and time-in-service requirements per AR 600-8-19.
  • 02TA platoon SSB designation: two to three radar sections assigned, full platoon equipment responsibility signed for.
  • 03First QTB input cycle: radar-readiness posture, section training plan, counterfire exercise schedule defended at battery level.
  • 04First NCOER cycle as rating official: three to four section NCO NCOERs, written against measurable counterfire and readiness outputs.
  • 05CTC rotation as TA platoon SSB: the OC/T evaluates the platoon's emplacement, detection rate, and reporting against ARTEP-MTP collective task standards — this is the SSB's performance test, not the section NCO's.
  • 06SLC slot competed and completed — required for E-7 board; build the packet before the platoon is in a train-up cycle.
  • 07MLC packet in progress — the SSB who has SLC complete and MLC prep underway before the SFC conversation arrives is the SSB the FA HHB 1SG recommends first.
Common Screwups
  • ×Inflating NCOER bullets on a section NCO who underperformed — the senior rater who contradicts your rating at the HHB NCOER review is doing it in front of the FA battalion CSM, and the SSB who cannot defend a bullet with facts is the SSB whose credibility ends that day.
  • ×DUI or Article 15 at E-6 — promotion flag, NCOER blast, relief-for-cause risk, and a reenlistment-code conversation at a rank where the re-entry options narrow fast.
  • ×Hiding a radar system's operational fault from the FA battalion S4 to avoid looking like the red section — the S4 finds out on the next readiness report, the parts timeline was already tight three weeks ago, and the SSB who obscures readiness problems is the SSB the FA battalion commander stops trusting.
  • ×Letting counseling lapse to quarterly or annual because the section NCOs 'are performing fine' — monthly DA 4856s are not bureaucracy, they are the paper chain that protects your section NCOs and makes adverse actions defensible. Skip them and the first Article 15 investigation reveals the gap.
  • ×Missing the SLC window because the platoon was always 'about to go to the field' — the platoon is always about to go to the field. Attend SLC when the window is offered; the next one may be eighteen months away and the E-7 board does not wait.

A Day in the Life

  • 0530PT formation — at SSB you set the platoon PT plan and you run with the platoon. The section NCOs lead their sections; you observe and coach. If a section NCO is dragging the formation pace the platoon sergeant knows before the next day's PT.
  • 0630–0700Shower, change, chow.
  • 0730Platoon accountability confirmed with the platoon sergeant. Any overnight soldier issues land with you before the formation; the section NCO who texted the platoon sergeant directly about a barracks incident without informing you first will hear about that during the counseling.
  • 0900Platoon formation. Confirm the day's training plan with the section NCOs. If there is a QTB this week you already have your section-status slides done; if the section NCO who owns the radar has a maintenance fault you know about it now, not at 1300.
  • 0915–1130Training block: section emplacement drill coordination, multi-section counterfire exercise run-through, PMCS review across the platoon, or NCOER work if you have a rating period closing. On exercise days you are at the platoon command post running section timing and monitoring the detection output from each section's report.
  • 1130–1300Lunch — unless a maintenance issue is going sideways, in which case you are in the motor pool coordinating with the FA battalion S4's maintenance officer and the section NCO who owns the faulted radar.
  • 1300–1600Afternoon: counseling sessions with section NCOs (one or two per week on a rotating schedule), radar-readiness review and update to the platoon log, coordination with the FSO for upcoming counterfire exercise sector assignments, or SLC packet work on slow weeks.
  • 1600–1700End-of-day formation. Section NCO status to you; your status to the platoon sergeant. Any soldier issues that need to go to the 1SG go through the platoon sergeant, not around him.
  • EveningSLC packet or MLC prep, NCOER draft review, or personal time. The SSB at this rank who is not actively building the next career gate is the SSB who finds the gate closed when the promotion window arrives.

Weekly Cadence

Monday carries the administrative weight: section readiness reviews, counseling schedule for the week confirmed, QTB input or NCOER review if those are in the cycle. Tuesday through Thursday are the training block: multi-section emplacement drills, counterfire exercise procedures, comms architecture practice, and operator task sustainment checks across sections. The section NCOs run their sections; you observe, coach, and coordinate the inter-section synchronization they cannot manage from inside their own section. Friday is motor stables and area cleanup, but in a pre-CTC rotation train-up Friday becomes another training day and the week before a field problem is consumed by PCCs: equipment inventories across the full platoon, CEOI pre-loads, generator service windows coordinated with the battalion S4, and a map rehearsal with the section NCOs on the rotation's emplacement sequence. During the field problem you are at the platoon CP for the first shift and pushing to each section position during the off-shift to check orientation records and PMCS status in person. The OC/T at a CTC rotation will visit each radar section during a live detection window; the SSB who has not visited his own sections before the OC/T does is the SSB who finds out about problems in the AAR. The quarterly rhythm is set by the QTB cycle. Four to six weeks before the QTB, bid survey time and range windows through the S3. Two weeks before, have the section-status slides built. The week before, confirm the inputs with the platoon commander. The SSB who shows up to the QTB with the same slides the platoon commander saw for the first time that morning is the SSB who makes the platoon commander look unprepared.

Key Skills — How to Drill Each

  1. 01
    Plan and synchronize a multi-section TA platoon emplacement — sector-of-search assignments, overlapping coverage, alternate positions, survey priority, and comms architecture — aligned to the FA battalion FSO's counterfire priorities.
    Start with the FSO's counterfire priorities and work backwards to emplacement geometry: what sectors need coverage, what terrain provides adequate look angles, what survey assets are available, and what the section NCO rotation for displacement looks like. Then synchronize the survey team's schedule against your emplacement plan — the radar section that arrives at a position the survey team has not yet certified cannot open its sector of search. Run a map rehearsal with the section NCOs before any displacement. The section NCO who shows up to the rehearsal not knowing his alternate position has a SSB who did not run the rehearsal right.
  2. 02
    Defend a TA platoon input to the FA battery or HHB Quarterly Training Brief — METL-aligned, realistic against the survey and maintenance schedule, with a clean LOE the platoon commander defends at battalion BUB.
    Build the training plan four to six weeks out, bid survey windows and range time through the S3 before the QTB brief, and validate the PMCS schedule against the battalion's upcoming training events. The QTB brief that arrives with schedule conflicts the S3 already knew about and unresourced training events is the brief that embarrasses the platoon commander. Give him a plan he can defend without caveats. The LOE must map to actual METL tasks with observable standards, not aspirational training events.
  3. 03
    Write three to four section-NCO NCOERs per cycle that the senior rater can defend — bullets tied to measurable counterfire detection rates, orientation-check pass rates, system readiness percentages, and counseling chain quality.
    Keep a running notes file on each section NCO through the rating period. Every CTC rotation, every QTB input, every counterfire exercise, every counseling review — document the output. The NCOER bullet is the compressed version of twelve months of observed performance; if you cannot produce the supporting data when the senior rater asks, the bullet did not happen. Write the draft at the nine-month mark; do not reconstruct twelve months of work in the final two weeks.
  4. 04
    Manage the platoon's radar-readiness posture across all sections — operational status, PMCS schedule, parts-on-order tracking, and the honest deadline rate the FA battalion S4 is working from.
    Run a weekly readiness review with the section NCOs: system status per TM-defined criteria, parts-on-order age, upcoming calibration or scheduled-maintenance windows, and any faults in the queue. Report to the platoon commander honestly — a 'green' radar that is running with a known processor fault because the part is on backorder is not green; call it orange and tell the S4 what is on order. The FA battalion commander's readiness brief is built off your input; a false color on your section's radar becomes the CO's false brief to the division.
  5. 05
    Integrate with the FA battalion FSE, the BCT fires cell, and the supported maneuver brigade's fires and intelligence cells on the counterfire targeting cycle.
    Read ATP 3-09.24 for the BCT counterfire framework and know the fires coordination authority chain: who requests counterfire, who processes the grid, who releases the cannon battery. The TA platoon SSB who understands the full cycle can push back intelligently when the FSO assigns a sector of search that conflicts with terrain geometry. The one who only knows his section's piece cannot. Attend the battalion fires BUB when the PSG invites you; that is the meeting where counterfire sector assignments are contested and the SSB who is not there loses the argument by default.
  6. 06
    Mentor section NCOs and senior operators through honest 131A FA Targeting Technician warrant officer pipeline conversations.
    The honest conversation is not 'you should think about it.' It is a sit-down with the section NCO and the battalion's 131A warrant officer as the reference point: here is what the selection board looks at, here is where your GT score and your ACFT stand, here is what the warrant officer in our battalion said about your candidacy when I asked him directly. The SSB who does this annually produces 131A candidates. The SSB who defers the conversation produces section NCOs who miss the application window by six months.

Manuals & References — What Chapters Matter

  • FM 3-09 — Field Artillery Operations.
    At SSB, read the target acquisition integration and counterfire planning chapters with a focus on the fires coordination framework your platoon plugs into. The section NCOs know how the radar works; you need to know how the counterfire data flows from your sections through the fires cell to the cannon battalion, and what the planning timelines look like from the battalion FSO's perspective. That knowledge is what makes your QTB inputs credible.
  • ATP 3-09.24 — Field Artillery Support of the Brigade Combat Team.
    The doctrinal home of the TA platoon's mission inside the BCT. The emplacement geometry chapter, the sector-of-search assignment framework, and the counterfire coordination procedures — know these before you contest a FSO's sector assignment. The SSB who can cite the doctrinal standard for overlapping radar coverage in a multi-section TA platoon is the SSB the FSO listens to when the assignment looks wrong.
  • AR 623-3 and DA PAM 623-3 — Evaluation Reporting System.
    This is the regulatory foundation for the NCOERs you write. Know the rating scheme, the block definitions, the rater and senior rater relationship, and the prohibited language. The DA PAM 623-3 has annotated examples; read the ones closest to your section NCO population. The NCOER that violates the reg — using prohibited superlatives, missing a required entry, or showing rater/senior rater block distributions that contradict the bullet content — comes back from the senior rater during the review and eats time you do not have.
  • ATP 3-09 — Fires; ATP 3-09.50 — The Field Artillery Cannon Battery.
    ATP 3-09 frames the broader fires integration architecture; ATP 3-09.50 explains how the cannon battery processes and executes the counterfire grids your sections produce. Understanding what happens to your section's grid after it leaves the mission processing cell — who reviews it, who clears the sector, who gives the fire command — gives you the context for why your sections' report formatting and timing standards are exactly what they are.
  • AR 600-8-19 — Enlisted Promotions and Reductions.
    You need to know this for your section NCOs' promotion timelines — the BLC/ALC requirements, the promotion-point worksheet, the board-eligibility dates — and for your own SLC and E-7 eligibility math. The section NCO who misses the ALC window because the SSB did not track the eligibility date is a problem the FA HHB 1SG blames on the SSB. Pull the current HRC MILPER messages on promotion point cutoffs quarterly.
  • ATP 6-22.1 — The Counseling Process; AR 600-20 — Army Command Policy.
    ATP 6-22.1 is the how-to for the DA 4856 counseling chain you need to maintain on three or four section NCOs per cycle. AR 600-20 is the legal framework of your NCO authority over your soldiers — limits of punishment, command relationships, the UCMJ references you need when the Article 15 conversation arrives. Read both before the first adverse action, not after.

Standards — How to Hit Each

  • ALC graduate — required for E-7 board; SLC packet ready when the E-7 conversation enters the picture.
    ALC is the first gate and it is not flexible — no ALC, no E-7 board. SLC is the second gate and the windows are more limited; the SSB who waits for the ideal training-cycle moment to attend SLC finds that the ideal moment never arrives. Build the SLC packet while the platoon is in garrison and bid the window through the FA battalion S3's school-seat request process. The HHB 1SG fights for slots for the SSBs whose packets are already complete.
  • TA platoon counterfire detection rate at or above the FA battalion METL standard across the last live exercise or CTC rotation.
    The detection rate is the output metric the battalion FSO briefs. Before a CTC rotation or collective counterfire exercise, review each section's last orientation-check pass rate and system readiness history; the sections with recent faults are the sections you watch more closely during the exercise. Post-exercise, analyze the detection gaps: terrain mask, system fault, operator gap, or orientation error — each has a different fix and you need to be able to defend the analysis at the after-action review.
  • NCOER bullets on measurable outputs — section operational status rate, detection rate at the last exercise, orientation-check pass rate, PMCS deadline rate.
    The rule for SSB NCOER writing is: if you cannot state a number or cite an event, the bullet is an opinion. 'Led section to T-rating at CTC rotation' is a fact you can defend. 'Demonstrated outstanding leadership qualities' is an opinion the senior rater will reword or return. Build the supporting evidence file on each section NCO at the start of the rating period and keep adding to it through the year. The NCOER written from twelve months of notes is credible; the NCOER written from memory in the last two weeks is not.
  • Section NCOs you rated advancing on schedule — ALC-eligible and board-competitive when their promotion window opens.
    Track each section NCO's ALC eligibility date, promotion-point worksheet, and school completion status in a simple tracking document. Review it at every quarterly counseling. The section NCO who misses a school window because the SSB forgot to put in the request is a loss the FA HHB 1SG attributes correctly. Your job is to create the conditions for the section NCO's career to move; the section NCO's job is to do the work. Separate those responsibilities clearly.

Technical Mistakes — Concrete Consequences

  • Letting one section's orientation or PMCS discipline drift because you trust that section NCO.
    The section that gets the IG visit or the safety inspection is the one with the deferred maintenance and the orientation records that have not been re-verified since the last displacement. The battalion commander does not separate 'I trusted him' from 'you are the SSB responsible for that section's standards.' You signed the readiness report; the fault is yours to own.
  • Writing NCOER bullets as wish-lists or future potential rather than documented past performance.
    The senior rater at the FA HHB NCOER review will ask what data supports the Top Block recommendation. If the answer is 'he has a lot of potential and a good attitude,' the rating comes back marked down and the SSB who inflated is now the SSB the FA battalion CSM watches at every subsequent NCOER cycle. The section NCO also loses a rating he may have earned if the SSB had documented the evidence.
  • Reporting the platoon counterfire posture as 'green' when you know a section is running with an orientation fault or a system processor alert.
    The CTC OC/T finds the fault on day two of the rotation. The battalion FSO's counterfire detection slide goes red and he traces it to the section that was degraded — the section the SSB called green on the readiness report. The post-rotation AAR names the discrepancy; the battalion commander asks the 1SG about the SSB's readiness reporting integrity, and that is a career-level conversation in a platoon this small.
  • Letting weapons and sensitive-item accountability slip during a displacement because the section NCOs are handling the radar system.
    A missing fire-control fill device or a cryptographic item left at a former position generates a lost-item investigation that halts the TA platoon's training schedule for a week and triggers a 15-6 investigation. The SSB who signed the hand receipt for the section's sensitive items owns the accountability failure whether or not he was physically present at the position when the item went missing.

Career Decisions at This Rank

  • Attend SLC now versus deferring to the next cycle.
    SLC is a 22-day resident course and it is the STEP gate for the E-7 board — there is no path around it. The window opens roughly when you are eligible by date of rank, and it closes when the course seat cycle ends. The SSB who says 'I will go next year when the platoon tempo is lower' is the SSB who discovers that the tempo never lowers on schedule and the next window is fourteen months away. The FA HHB 1SG can fight for an early window for the SSB whose packet is ready; he cannot fight for the SSB who has not built the packet. Go when the window is offered.
  • MLC application — apply during E-6 or wait until early E-7.
    The Master Leader Course is a career-broadening course designed for senior SSGs and new SFCs — the application timing is usually in the E-7 zone, but some SSBs begin the MLC conversation with the 1SG while still a SSG. The value of MLC at the SSB-to-SFC transition is that it builds the institutional leadership framework that the SFC platoon sergeant role requires on day one. The SSB who has MLC complete before or immediately after SFC pin-on is ahead of the peer who is still on the waitlist. Ask the FA HHB 1SG directly about MLC timing; she knows the FA branch's current demand signal.
  • Branch transfer from 13R to 131A FA Targeting Technician warrant officer — apply now or close the window.
    The 131A warrant officer path is the most natural technical off-ramp from a 13R career with strong radar and counterfire foundations. The selection board reviews GT score, ACFT, the chain's recommendation, and the depth of 13-series technical experience. The SSB who has spent four to six years in TA sections is a competitive applicant if the record is clean. The honest caveat: the 131A warrant officer accesses at WO1 and serves in fire support targeting roles at battalion and brigade level. The pay and the responsibility are different from a SSB section NCO position; the FA branch's 131A warrant officers are the technical targeting experts the fires cell leans on. The SSB who has talked to the battalion's 131A warrant officer honestly — not just glanced at the application packet — knows whether the path fits him. Have that conversation before the application window opens, not during it.
  • Stay in the 13R/13Z line versus pursue the FA Master Fires Sergeant Course at Fort Sill as a senior SSB.
    The Master Fires Sergeant Course at Fort Sill is the FA branch's senior NCO technical credential for the FA fires enterprise. It is not an SFC prerequisite, but it is a visible credential that senior FA NCO assignment officers and battalion CSMs look for when they are selecting the TA platoon sergeant and FA HHB 1SG slate. The SSB who attends Master Fires during the late SSB zone arrives at SFC with a technical credential the FA branch values and a network of senior FA NCOs from every fires MOS family. The course availability and admission criteria should be confirmed directly through the FA branch NCO proponent at Fort Sill — the course has evolved and the current enrollment process is the authoritative source.
  • Reenlist for the SSB-to-SFC transition versus separating with a TS/SCI clearance and Q-53 background.
    A SSB 13R who separates at six to ten years of service with a TS/SCI clearance, Q-53 operator and section leader experience, and an ALC completion has a marketable background in the defense contracting world. Northrop Grumman, General Dynamics, Raytheon, and the specialized defense EW and radar contractors hire cleared technicians with counterfire radar experience. The entry point is typically a mid-level technical specialist or field service representative role. The honest comparison: the Army path to SFC and eventually 1SG or CSM is well-lit but requires seven to twelve more years of service; the contractor path offers a faster transition to civilian compensation but without the NCO pension math. Run the full twenty-year pension calculation against the civilian salary before deciding. Both paths are defensible; neither is obviously right for every SSB.

How the Seat Varies by Unit Type

  • Active component FA HHB TA platoon (IBCT, SBCT, ABCT).
    The standard SSB environment. You have two or three Q-53 sections, a regular CTC rotation cycle, and the FA battalion FSO running the counterfire requirement at full BCT-support intensity. The 131A warrant officer is present. The NCOER competition is real. The SLC and MLC pipelines are active through the FA battalion S3 school-seat process. This is where the counterfire craft is maintained at the highest regular-Army training level.
  • DIVARTY or corps-level TA battalion.
    At echelons above brigade, the TA platoon SSB operates in a more complex fires integration environment — multiple BCTs, longer-range detection architectures, interface with joint fires and intelligence cells. The counterfire mission planning is more layered and the SSB who understands the multi-BCT targeting cycle is developing expertise that distinguishes him at SFC and beyond. The NCOER competition is also more senior; the section NCOs you are rating are competing for the same pool of SFC slots as section NCOs from BCT-level TA platoons.
  • Reserve Component FA battalion (USAR/ARNG).
    One weekend per month and two weeks annual training. The SSB in an RC TA platoon manages a training tempo challenge that active component SSBs do not face: maintaining section NCO operator task currency and radar readiness certification across eleven months of limited drill time. The QTB cycle is still present but less frequent, and the AGR (Active Guard/Reserve) soldiers in the unit carry more of the daily readiness load. If you are a traditional RC SSB, the SLC and MLC pipelines run through the RC school-seat system with different timelines than AC. If you are AGR the pace looks more like active component.
  • Deployed TA platoon supporting a BCT in a combat or theater environment.
    In a deployed environment the TA platoon SSB's job is stripped to its core: sections emplaced, sectors of search assigned, detection output clean, counterfire grids formatted correctly and out before the enemy crew relocates. The maintenance challenge is acute — the Q-53's supply chain is long when you are deployed, and a section that goes deadline overseas without a parts pipeline does not come back online quickly. The SSB who has built a strong relationship with the FA battalion S4 and knows how to work the theater Class IX supply process before deployment keeps his sections operational. The one who hasn't has a degraded picture when it matters most.

What Good Looks Like at This Rank

The good TA platoon SSG has a platoon the FA battalion FSO names at brigade fires BUB without hesitation. Not because the SSB gives a polished brief — because the platoon's detection rate leads the battalion, the orientation records are clean going back to the last CTC rotation, the section NCOs are NCOER-board-ready and know it, and the radar operational status is reported accurately regardless of whether the color is green or red. The FA battalion commander trusts what the SSB tells him about counterfire readiness because it has been correct before. Beyond the technical output, the good SSB is the senior NCO each section NCO goes to with the career question they would not ask in formation. The 131A FA Targeting Technician conversation is not a hallway vague encouragement — it is a scheduled sit-down with the battalion's 131A warrant officer as a reference, after the SSB has reviewed the section NCO's record and given him an honest assessment of where he stands. The section NCO who applied for 131A and was selected prepared well because the SSB ran the honest conversation. The section NCO who was not selected knows specifically what to fix before the next window. The SLC packet is built and ready before the platoon deploys to the CTC rotation. The SSB does not wait for a slow week that does not arrive; he builds the packet during the six-week lull between rotations and tells the 1SG it is ready. When the E-7 window opens, the FA HHB 1SG fights for this SSB's slot because the administrative friction is zero and the NCOER profile is clean. That is the career that moves forward on the SSB's schedule, not the Army's.

Preview — The Next Rank

At SFC you stop running the sections and start running the platoon sergeant job — and the TA platoon sergeant role in an FA HHB is one of the most technically and organizationally complex PSG seats in the FA branch. You own two or three section NCOs who are where you were twelve months ago: capable, technically grounded, and still learning that their job is to develop the soldiers below them rather than just outperform them. Your job at SFC is to turn that into a platoon where the section NCOs run without your hand on every section, where the counterfire output is reliable across all three sections, and where the platoon leader gets fires-officer credit in his OER because your platoon's detection rate was the one the FA battalion FSO cited. The counseling load doubles. You write section-NCO NCOERs now, but at SFC you are also running the platoon as acting 1SG when called, attending battalion-level training meetings, and coordinating with the BCT fires cell on counterfire sector assignments. The 1SG conversation starts the moment you pin SFC — the FA HHB 1SG is watching the TA platoon sergeant to see whether you are building a 1SG-ready career or a platoon-sergeant-for-life career. The MLC completion and a clean NCOER profile are the evidence she looks for. The SFC who has MLC done and two clean NCOERs as a PSG is the SFC the battalion CSM puts on the 1SG selection list early.
FAQ

13R E6 — Frequently Asked Questions

Q01What does a E6 13R (Field Artillery (FA) Weapons Locating Radar (WLR) Specialist) actually do?
You run a TA platoon with two to three radar sections — each fielding a Q-53, Q-36, or Q-37 — and you are responsible for their training, their equipment, their operational readiness, and the grids they put into the counterfire mission processing cell.
Q02What's the most important thing to know as a E6 13R?
At SSG you stop running one radar section and start running two or three.
Q03What does a typical day look like for a E6 13R?
Time-blocked day at the E6 13R rank tier: 0530 PT formation — at SSB you set the platoon PT plan and you run with the platoon. The section NCOs lead their sections; you observe and coach. If a section NCO is dragging the formation pace the platoon sergeant knows before the next day's PT, 0630–0700 Shower, change, chow, 0730 Platoon accountability confirmed with the platoon sergeant.

Q04What mistakes get E6 13R soldiers fired or relieved?
Inflating NCOER bullets on a section NCO who underperformed — the senior rater who contradicts your rating at the HHB NCOER review is doing it in front of the FA battalion CSM, and the SSB who cannot defend a bullet with facts is the SSB whose credibility ends that day; DUI or Article 15 at E-6 — promotion flag, NCOER blast, relief-for-cause risk, and a reenlistment-code conversation at a rank where the re-entry options narrow fast;…
Q05What career decisions matter most at the E6 13R rank tier?

FM 3-09 — Field Artillery Operations.; ATP 3-09.24 — Field Artillery Support of the Brigade Combat Team.; ATP 3-09 — Fires; ATP 3-09.50 — The Field Artillery Cannon Battery (the fires chain your platoon feeds).
