HEADS UP

The TA platoon sergeant seat is where careers either take off toward 1SG and the CSM track, or plateau into a permanent SFC billet. The difference is almost never the radar work — it is whether the platoon sergeant built section NCOs, ran the fires coordination interface honestly, and managed the 131A FA Targeting Technician warrant pipeline with real intent. The FA HHB 1SG is watching all three. The battalion FSO is watching the first and the second. Start demonstrating all three from the first month.

The Honest MOS Read
SFC in a TA platoon is a dual-role seat: platoon sergeant to the platoon, and senior technical voice to the FA HHB on counterfire and target acquisition. Neither role forgives the other. The SFC who runs a technically excellent counterfire mission but cannot hold a family readiness meeting or write an NCOER that the senior rater defends is not going to 1SG. The SFC whose section NCOs love working for her but whose platoon's detection rate is mediocre is not going to 1SG either. The seat requires both, simultaneously, across a two-to-three-year tour that will include at least one CTC rotation, a real or simulated deployment, and three or four quarterly training brief cycles with the FA battalion FSO and the battalion S3. The platoon sergeant's most important leadership task is not a task on the training schedule. It is the one-on-one honest conversation with each section NCO about where their career actually stands. The section NCO who has been drifting on his ALC timeline because nobody told him it was urgent needs to hear it from the platoon sergeant — specifically, with a date, with the consequence named, and with a Plan of Action that has the section NCO's signature on it before he leaves the vehicle. The section NCO who is ready to apply for 131A but has been waiting for the platoon sergeant to confirm it needs the platoon sergeant to make the call to the warrant officer in the battalion the same week, not the same month. The platoon sergeant who runs the development conversation with that precision is the platoon sergeant who produces section NCOs the FA HHB CSM can use. The counterfire output relationship with the FA battalion FSO is a professional relationship that requires the platoon sergeant to disagree productively. The FSO will assign sector-of-search parameters, emplacement geometry, and detection priorities. Some of those assignments will be tactically sound. Some will conflict with the survey team's timeline, the terrain along the designated axis, or the section's maintenance window. The platoon sergeant who says yes to everything and delivers a degraded picture has betrayed the FSO's planning. The platoon sergeant who pushes back with specific reasoning — terrain mask at the assigned position reduces detection geometry by this estimate, and the alternate position at grid X gives us better look angles while the survey team can certify it by H-minus-four — is the platoon sergeant the FSO goes to the next time the counterfire plan is contested. That relationship is built by being right and being honest, not by being agreeable. At SFC, 13R also begins the formal conversion to 13Z — Field Artillery Senior Sergeant. The 13Z designation reflects the FA branch's senior NCO career structure, which does not bind you to a single FA sub-MOS at this rank tier. A SFC with a 13R technical background may serve as TA platoon sergeant, as the FA HHB senior NCO, as a DIVARTY operations senior NCO, or in any other FA senior-NCO position the branch assigns. The 13Z conversion is administrative at the MOS level, but its practical meaning is that your career from this point is evaluated as an FA senior NCO rather than a 13R specialist. The FA branch wants its senior NCOs to understand the full fires enterprise — cannon, fire direction, rocket, and target acquisition — not just the system they operated as a junior soldier. MLC is the STEP gate for the E-8 board and the SFC who treats it as a bureaucratic hurdle is the SFC who misses the preparation it actually provides. The Master Leader Course covers the institutional and strategic leadership frameworks that 1SG and CSM candidates need before they walk into the hardest NCO leadership seats in the Army. The SFC who shows up to the 1SG selection board having only thought about fires and counterfire has gaps in her institutional leadership vocabulary that the board will find. MLC closes those gaps before the board, not after. The family readiness piece is real and it is yours to own. Radar platoons deploy on short notice and on little warning. The families of the soldiers in your platoon will need points of contact, information pipelines, and a platoon sergeant who has built that infrastructure before the deployment order arrives — not in the seventy-two hours after it. The SFC who treats family readiness as something the spouses manage without the NCO chain's involvement will find out she was wrong on the third day of the deployment when a family emergency surfaces that nobody in the chain had context for. Build the family readiness roster, hold the pre-deployment briefing, and attend the family readiness meeting. It is thirty minutes a quarter; the operational cost is zero and the deployment-readiness return is real.
Career Arc
  • 01SFC pin-on — post-SLC, post-promotion board, time-in-grade and time-in-service per AR 600-8-19; 13Z MOS designation begins at SFC.
  • 02TA platoon sergeant designation in an FA HHB: two to three radar sections, full platoon METL ownership, platoon commander development as secondary mission.
  • 03First complete NCOER cycle as TA platoon sergeant: three to four section-NCO NCOERs, with measurable counterfire output bullets the senior rater can defend.
  • 04CTC rotation as platoon sergeant: the OC/T evaluates platoon-level counterfire emplacement, detection output, and mission processing against ARTEP-MTP collective task standards — this is the SFC's performance test at full scale.
  • 05MLC completion — required for E-8 board competitiveness; attend while in the platoon sergeant seat, not after promotion to E-8.
  • 06131A FA Targeting Technician warrant pipeline producing at least one selected candidate from the platoon in the SFC's rating period — the FA branch notices platoon sergeants who run this pipeline seriously.
  • 071SG screening conversation with the FA HHB battalion CSM — typically begins during the SFC's second or third year in the PSG seat if the NCOER profile and MLC completion are in order.
Common Screwups
  • ×Going to the FA HHB CSM around your 1SG with a problem you should have brought to the 1SG first — you will be wrong, the 1SG will find out by the afternoon, and the CSM will tell you what the 1SG already said.
  • ×DUI or fraternization at SFC — in a platoon this size these are immediately visible to the battalion; the relief-for-cause conversation with the 1SG and the battalion commander happens within forty-eight hours and does not produce a second chance at this rank.
  • ×Writing NCOER bullets on section NCOs that the senior rater cannot defend — the FA HHB NCOER review at battalion level will expose inflated ratings, and the SFC who inflated section NCOs who underperformed has a credibility problem with the battalion CSM that does not repair.
  • ×Letting the family readiness piece drift because you believe the spouses handle it — one family emergency during a deployment where the platoon sergeant cannot account for who the family contact is becomes a battalion-level command climate conversation.
  • ×Skipping or deferring MLC because the platoon tempo is always high — MLC is the STEP gate for the E-8 board and there is no equivalent bypass. The SFC who cannot show MLC completion on the board packet does not make 1SG through the competitive FA branch.

A Day in the Life

  • 0530PT formation. You run with the platoon but the section NCOs lead their sections. You are observing the section NCO who you are counseling this week on ACFT event weaknesses — you noted it in his counseling draft yesterday.
  • 0630–0700Shower, change, chow.
  • 0730Platoon accountability and section NCO check-in. Any overnight soldier issues are at your desk before the formation. The section NCO who texted the 1SG about a barracks problem without informing you first will have a counseling conversation that morning.
  • 0800Platoon leader coordination — the day's training priorities confirmed, any battalion BUB inputs needed, any fires coordination updates from the battalion FSO. The platoon leader briefs; you provide the section status inputs.
  • 0900Platoon formation. Training plan confirmed, section NCOs know the day's sequence and expectations before the formation dismisses.
  • 0915–1130Training block: you are at the most complex section training event — multi-section emplacement drill, counterfire exercise run-through, or the section with the current orientation-check gap you identified in last week's PMCS review. The section NCOs run their sections; you observe, coach, and synchronize the inter-section timing.
  • 1130–1300Lunch — unless there is a QTB this week, in which case you are reviewing the platoon commander's slides for accuracy before the afternoon brief.
  • 1300–1600Afternoon: NCOER draft work, counseling sessions with section NCOs (one or two per week on a rotating monthly schedule), family readiness coordination for the upcoming deployment cycle, or acting 1SG duties if the 1SG is TDY. On exercise days this is the post-mission analysis and AAR preparation window.
  • 1600–1700End-of-day formation. Section NCO status consolidated up to you; your status to the 1SG. Any soldier issues that need the 1SG go through you first — always.
  • EveningMLC prep, NCOER drafts, or the 131A follow-up email you said you would send to the warrant officer. The SFC who does this work in the evenings rather than waiting for administrative time that never materializes is the SFC whose career moves on schedule.

Weekly Cadence

Monday carries the administrative weight: section status confirmed, NCOER and counseling calendar reviewed for the week, QTB input validated if it is in the cycle, and the family readiness check — one phone call or text to the FRG coordinator to confirm anything surfaces before the battalion reads it elsewhere. Tuesday through Thursday carry the training block: multi-section emplacement drills, counterfire exercise procedures, comms architecture practice across sections. You are moving between sections, not supervising one. Friday is motor stables, area cleanup, and the week's final counseling session if one is scheduled. The pre-CTC rotation cycle is the most demanding sustained period of the PSG tour. Eight to twelve weeks out, the platoon training plan is finalized, survey resource bids go to the S3, school seats requested, and the section NCOs begin the PCC cascade. Six weeks out, the platoon runs the first multi-section emplacement rehearsal in the training area. Four weeks out, the garrison counterfire exercise is run to the ARTEP-MTP task standard — graded honestly, with a formal AAR naming the sections that passed and the sections that need a second run. Two weeks out, the final pre-deployment family readiness meeting. The week before departure, full PCI across all sections with your signature on the platoon readiness report. During the CTC rotation the SFC is at the platoon command post for the first detection window of each section, then pushing to each section position during the off-shift to check orientation records and PMCS status in person. The OC/T will visit each section during a live detection window; the PSG who has visited her sections before the OC/T shows up is the PSG whose sections perform because they know she is watching. The PSG who only comes out during the AAR does not have that effect.

Key Skills — How to Drill Each

  1. 01
    Build a quarterly TA platoon training plan that integrates radar emplacement, counterfire exercise, survey support, and maintenance windows against the FA battalion S3 training calendar — realistic resource bids, locked.
    Start with the battalion's quarterly training calendar and work backwards to resource bids: survey team availability, range time for live counterfire exercise, generator service windows, school-seat requests for section NCOs. Bid all of these through the S3 four to six weeks before the QTB. Arrive at the QTB with a plan that has no unresolved resource conflicts. The platoon commander defends the input at the battalion BUB; the platoon sergeant who gave him an unresourced plan is the platoon sergeant who makes him look unprepared.
  2. 02
    Write three to four section-NCO NCOERs per cycle — bullets tied to measurable counterfire detection rates, orientation-check pass rates, system readiness percentages, and counseling-chain quality; drafts submitted to the senior rater at least two weeks before the closing date.
    Keep a monthly performance log on each section NCO. Every CTC rotation, every counterfire exercise, every counseling review produces observable, documentable evidence. The NCOER bullet is the twelve-month compression of that log; if you cannot defend it with specific events and numbers the senior rater will ask for, rewrite it before you submit. Submit drafts two weeks before the closing date so the senior rater has time to review and request changes without the administrative rush creating errors.
  3. 03
    Run the platoon-level counterfire exercise to the ARTEP-MTP 'T' rating — section emplacement certification, live detection drill, mission processing, counterfire headquarters interface.
    Run the exercise sequence in garrison at least twice before the CTC rotation: a full run-through with all sections in a training area, graded by section against the ARTEP-MTP task list, with a formal AAR that names the gaps and the fixes. The OC/T at the CTC rotation is evaluating the platoon against the same standard; the section that fails the orientation check step in the field problem failed it in garrison first and nobody fixed it. The garrison rehearsal is where you find those gaps, not at the CTC.
  4. 04
    Mentor three section NCOs into SFC-board-ready candidates without losing your own edge on MLC preparation and the institutional leadership requirements of the PSG seat.
    Separate the section NCO development cadence from your own career prep. The section NCO development is a monthly counseling conversation with specific goals and a Plan of Action the section NCO owns. Your MLC preparation is separate time — evenings, PCS leave, or a gap period before a deployment — that you protect. The SFC who subordinates her own career preparation to the section's rhythm is the SFC who arrives at the 1SG board with a preparation gap she cannot explain.
  5. 05
    Translate the 131A FA Targeting Technician warrant officer pipeline conversation into honest career counseling for the platoon's SPCs and SGTs — not a brochure conversation but a real candidacy assessment.
    The honest assessment requires you to sit down with the soldier, review his record against what the 131A selection board actually looks for (GT score, ACFT, chain recommendation, technical experience depth), and then call the battalion's 131A warrant officer to ask whether he would endorse this soldier as a credible applicant. The platoon sergeant who does this for every eligible soldier in the platoon is the platoon sergeant who produces 131A candidates. The one who hands out the packet and says 'you should look into it' produces soldiers who apply unprepared and are not selected.
  6. 06
    Operate as the FA HHB acting 1SG when called — accountability formation, sick call, supply and equipment accountability, family readiness, casualty notification awareness.
    The acting 1SG role is not a favor the platoon sergeant does for the 1SG when she is TDY; it is a preview of the seat the SFC is being evaluated for. Know the orderly room's standing operating procedures before you need them under time pressure. Know where the casualty notification procedures are documented and what the CO's standing guidance is. Know the supply room sergeant's name and the battalion's property accountability officer's contact. The acting 1SG who discovers these things for the first time while sitting in the 1SG's chair is the SFC who does not demonstrate readiness for the seat.

Manuals & References — What Chapters Matter

  • FM 3-09 — Field Artillery Operations.
    The doctrinal foundation of everything the TA platoon does and everything the fires chain above it requires. At SFC you need to own the target acquisition and counterfire chapters completely — not to recite them but to apply them when the FSO assigns a sector-of-search that conflicts with your platoon's survey geometry or detection capability. The SFC who can cite chapter and paragraph when pushing back on a sector assignment is the SFC the FSO respects.
  • ATP 3-09.24 — Field Artillery Support of the Brigade Combat Team.
    The operational playbook for how the TA platoon fits into the BCT fires fight. At SFC, focus on the fires coordination authority chain — who requests counterfire, who processes the grid, who releases the cannon battery — and the planning timelines that drive your section's sector-of-search assignment window. Understanding the full counterfire cycle from the FSO's planning horizon back to your section's detection output is what makes the platoon sergeant's QTB input credible and the counterfire exercise AAR analysis specific.
  • AR 623-3 and DA PAM 623-3 — Evaluation Reporting System.
    The regulatory foundation of the NCOERs you write on section NCOs and the NCOER you will receive from the platoon commander. The DA PAM 623-3 annotated examples are the practical reference; read the entries closest to the section NCO population you are rating. The most common PSG NCOER error is the rater and senior rater block distributions that contradict the bullet content — a Top Block rater mark next to a bullet that describes average performance will be questioned at the NCOER review.
  • AR 600-20 — Army Command Policy; AR 638-8 — Army Casualty Program.
    AR 600-20 is the legal backbone of the PSG's authority — command relationships, the limits of NCO authority, the Equal Opportunity and Sexual Harassment / Assault Response and Prevention requirements that the PSG is responsible for enforcing in the platoon. AR 638-8 is the casualty notification and reporting regulation that every senior NCO must know before the first serious incident, not after. At SFC the probability of being the senior NCO present at a serious event is real.
  • AR 350-1 — Army Training and Leader Development; DA PAM 350-9 — Index and Description of Army Training Devices, Simulators, and Simulations.
    AR 350-1 governs the Army's training management framework — the annual training guidance, the METL development process, and the individual and collective training standards the QTB is built around. DA PAM 350-9 is the reference for training device availability; knowing what the FA branch has in terms of Q-53 simulator access or counterfire training devices at Fort Sill helps you make a more realistic resource bid at the QTB than asking for live survey time for every training event.
  • TC 7-22.7 — The Army Noncommissioned Officer Guide; ADP 6-22 — Army Leadership and the Profession.
    TC 7-22.7 is the institutional NCO development reference the USASMA curriculum is built around. ADP 6-22 is the Army's doctrinal statement on leadership — mission command, values, the leader as developer of subordinates. At SFC in a TA platoon, ADP 6-22's 'leads, develops, achieves' framework is not abstract; it maps directly onto the platoon sergeant's three daily responsibilities: leading the section NCOs, developing them for the 1SG and SSB pipeline, and achieving the counterfire detection output the battalion FSO briefs.

Standards — How to Hit Each

  • SLC graduate; MLC completion on the record before the E-8 board.
    SLC is already behind you at SFC pin-on — it was the gate. MLC is the E-8 gate and the timing is in the early-to-mid SFC tour. The SFC who attends MLC in the first or second year of the PSG seat arrives at the 1SG board with the institutional leadership credential the board expects; the SFC who defers MLC to the third year is betting that the window will stay open and the deployment cycle will not close it. It will close it. Attend MLC when the window is offered.
  • Platoon ACFT pass rate at or above 95%; platoon counterfire exercise or CTC rotation detection output in the upper third of the FA battalion.
    The ACFT pass rate is the platoon sergeant's personal standard before it is the platoon's standard. A SFC who fails the test she enforces loses the platoon's respect before the next formation. For the detection rate, run the pre-CTC garrison exercise graded honestly against the ARTEP-MTP task standard. The section that fails the orientation check in garrison and is not corrected before the rotation will fail it under OC/T observation. The upper-third standard is not aspirational; it is the bar the FA battalion FSO expects the senior TA platoon sergeant to defend.
  • 131A FA Targeting Technician warrant pipeline producing at least one selected candidate from the platoon per year.
    This is a leadership output standard, not a technical one. It requires the platoon sergeant to run honest candidacy assessments with eligible soldiers, coordinate with the battalion's 131A warrant officer on applicant viability, and ensure that the application packets are complete and submitted before the window closes. The FA branch tracks accession rates; the TA platoon sergeant who consistently has zero 131A applications from her platoon is visible to the FA branch proponent at Fort Sill.
  • Zero senior-NCO-attributable reliefs or command climate investigations during the PSG tour.
    The command climate investigation that traces to the platoon sergeant's conduct — fraternization, financial misconduct, OPSEC breach, sensitive item accountability failure — ends the PSG tour and ends the 1SG candidacy. At SFC in a TA platoon you are a visible senior NCO in a small FA community. Conduct yourself at the standard you hold your section NCOs to, because the FA HHB CSM holds you to a higher one. The 1SG who is watching your PSG tour is watching for the senior NCO who is consistent in private and in formation.

Technical Mistakes — Concrete Consequences

  • Letting one section NCO drift on orientation discipline or PMCS documentation because you trust her record.
    The CTC OC/T pulls the section with the most recent complaint in the pre-rotation reconnaissance and finds orientation records that were not re-verified after a displacement. The battalion commander's post-rotation AAR names the section. The SFC who said 'I trusted that section NCO' has told the 1SG that she stopped supervising because she was comfortable, and that explanation does not carry weight in an FA HHB where every grid going to the counterfire cell is your responsibility.
  • Confusing being aligned with the platoon leader with being managed by the platoon leader.
    The TA platoon leader is a lieutenant or a captain learning the fires planner role. The SFC's job is to build the PL into a competent fires officer, not to substitute the PL's judgment for her own on counterfire technical matters where the SFC has more expertise. The SFC who defers to the PL on orientation geometry or sector-of-search feasibility because 'he outranks me' is the SFC who lets a bad counterfire plan go forward and watches it fail at the CTC rotation. Push back in private, before the plan is briefed, with specific technical reasoning. That is the PSG role.
  • Carrying a personal conflict with the FA battery FDC chief or a peer PSG into the battalion training meeting.
    FA battalion-level NCOERs at the HHB reflect the senior NCO chain's assessment of the entire enlisted force, not just your platoon. A SFC who is visibly at odds with a peer PSG in the battalion training meeting is a SFC the 1SG is managing rather than mentoring. The battalion CSM finds out within forty-eight hours of any senior NCO conflict that surfaces in a meeting. The career consequence is a NCOER comment on 'working within the NCO chain' that the senior rater uses at the 1SG selection board.
  • Treating the family readiness piece as the FRG coordinator's problem rather than the platoon sergeant's responsibility.
    A family emergency during a deployment — medical crisis, financial hardship, housing issue — that surfaces without a clear PSG awareness of the family's situation becomes a welfare check the battalion S1 and the Rear Detachment commander manage without you. When the battalion commander asks the 1SG why the platoon sergeant did not have situational awareness on a family issue in her platoon, the answer 'the FRG handles that' is not an acceptable answer. The PSG owns family readiness; the FRG coordinator is the resource, not the substitute.

Career Decisions at This Rank

  • Apply for the 1SG selection list — when and how.
    The 1SG selection in the FA branch is managed through the HRC field grade and senior NCO assignment process and the battalion CSM nomination cycle. The SFC who wants to be competitive for 1SG needs MLC complete, a clean NCOER profile across the PSG tour (two to three cycles minimum), and a battalion CSM who will make a specific nomination call on her behalf. The honest pathway: tell the battalion CSM directly that you are interested in the 1SG track, ask what she sees in your record that is not yet competitive, and then fix those gaps before the next NCOER closes. The SFC who waits for the battalion CSM to identify her for 1SG candidacy without expressing the intent has lower priority than the SFC who made the intent known and did the work.
  • USASMA / Sergeants Major Academy application — pursue while a SFC or defer to post-1SG.
    The Sergeants Major Academy at Fort Bliss is the Army's senior NCO professional military education requirement for SGM selection. Most SFCs who are on a legitimate CSM track attend USASMA as MSG or as 1SG — the sequence is typically SFC → MLC → 1SG → USASMA → CSM consideration. Attending USASMA as a SFC is possible through the Senior Leader Course; the timing depends on the FA branch's current accession pipeline and the SFC's assignment cycle. The honest question to ask the battalion CSM: 'Given my current profile and where the FA branch needs me, is this the right window for USASMA or should I focus on 1SG first?' That conversation should happen before you apply, not after.
  • 13Z assignment to FA fires enterprise versus staying on the TA-platoon/counterfire track.
    At SFC, 13R converts to 13Z and the assignment pool opens to the full FA fires enterprise — cannon, fire direction, operations, and targeting. Some SFCs with a strong TA and counterfire background are assigned to DIVARTY operations senior NCO positions or FA school senior NCO billets at Fort Sill rather than staying on the BCT TA platoon line. Those assignments build breadth that the FA branch values for the 1SG and CSM pipeline. The honest question is whether you want to deepen the counterfire technical expertise or broaden the FA fires leadership profile. Both are valid; the FA branch CSM proponent at Fort Sill is the authoritative source on which assignments are currently valued in the 1SG and CSM selection pipeline.
  • Post-service planning — defense contractor versus federal civilian versus a second career outside the defense industry.
    The SFC who begins post-service planning at fifteen years rather than nineteen has eighteen months to build the professional network and the credential baseline that makes the transition non-reactive. The 13R/13Z SFC with a TS/SCI clearance, Q-53 program experience, and a counterfire radar background has a specific market: Northrop Grumman's Firefly Q-53A upgrade program, General Dynamics and Raytheon in the fires systems domain, and the DoD GS-13 to GS-14 civilian technical advisor pipeline at Fort Sill FIRES CoE. The specific job titles and requisition cycles change; the network of former 131A warrant officers and senior FA NCOs who have already made the transition is the most useful source for what is actually available when you separate. Start that network now, not in month 239.

How the Seat Varies by Unit Type

  • Active component FA HHB TA platoon (IBCT, SBCT, ABCT).
    The standard SFC environment. Two to three Q-53 sections, a regular CTC rotation cycle, and the FA battalion FSO running the counterfire requirement at BCT-support intensity. The 131A warrant officer is in the battalion and accessible. The NCOER competition for the 1SG slate runs through the FA HHB battalion CSM. This is the environment the FA branch produces its 1SG candidates from; most of the FA HHB 1SGs have at least one tour as a BCT TA platoon sergeant.
  • DIVARTY or corps-level TA battalion.
    The counterfire mission is more complex at echelons above brigade — multiple BCTs, integration with joint fires, intelligence, and electronic warfare elements at the DIVARTY or corps fires cell level. The SFC in a DIVARTY TA battalion is developing expertise in the multi-BCT counterfire architecture that the FA branch's most senior positions require. The 1SG and CSM pipeline at this echelon is different from the BCT line; the battalion CSM here is evaluating SFC candidates against a broader fires integration standard.
  • TRADOC or FA schoolhouse assignment — Fort Sill.
    A SFC assigned to the FIRES Center of Excellence at Fort Sill as an instructor or small-group leader is in one of the most professionally developmental environments in the FA branch — working with the 131A warrant officers who train targeting technicians, the senior fires doctrine writers, and the FA branch professional development proponent. The assignment builds institutional fires knowledge that translates directly to the USASMA and the senior FA NCO career. The SFC who returns to the operational force from a Fort Sill assignment with an MLC complete is a highly competitive 1SG candidate.
  • Reserve Component FA battalion (USAR/ARNG).
    As a SFC in an RC TA platoon, you are likely managing the training challenge of maintaining two or three radar sections across one weekend per month and two weeks annual training. The 1SG path in the RC runs through the RC battalion CSM and the state G1 process, which is different from the active component pipeline. If you are AGR the pace looks more like active component and the 1SG selection process is closer to the AC model. If you are a traditional RC soldier at SFC, understand the RC-specific MLC timelines and the RC 1SG selection process before benchmarking against the AC pathway.

What Good Looks Like at This Rank

The good TA platoon SFC runs a platoon the FA battalion FSO names without hesitation at the brigade fires BUB — not because the platoon is louder than the others but because its detection rate is consistently at or above battalion standard, its orientation records are clean going back through the last three exercises, and the section NCOs are NCOER-board-ready and know it. The battalion commander knows the platoon's counterfire output by section, because the SFC briefed it that way. The FA battalion FSO trusts the platoon's sector-of-search feasibility assessments because the SFC has pushed back on bad assignments before and been right. Beyond the counterfire output, the good SFC is the senior NCO each section NCO trusts with the honest career question. The 131A conversation happened as a real candidacy assessment — one section NCO from the platoon was selected for 131A in the last cycle, and the SFC knows the names of the two others in the queue and what their records still need. The MLC is complete. The NCOER profile is clean. When the FA HHB 1SG walks the battalion CSM through the SFC slate, this name is at the top of the 1SG selection recommendation because the paperwork proves what the formation already knows. The family readiness piece is invisible in the right way: the deployment order comes down on short notice and every family in the platoon has a PSG point of contact, knows who to call in the Rear Detachment, and has attended the pre-deployment briefing. The SFC who built that infrastructure six months before the deployment does not manage family emergencies reactively during the rotation. She gets a message from the FRG coordinator, responds within two hours, and the family's situation is handled before it surfaces at the battalion level. That is what a 1SG-ready SFC looks like when the deployment is real.

Preview — The Next Rank

At 1SG you stop running a platoon and start running a company. FA HHB is not a rifle company or a firing battery — it is the FA battalion's headquarters company, which means you own the survey section, the met section, the target acquisition platoon, the fire direction center, the battalion staff enlisted force, the orderly room, the supply room, and the family readiness program. The number of moving parts makes the FA HHB 1SG seat one of the most complex 1SG billets in the FA branch. The counterfire technical background stays relevant as 1SG, but it is no longer the primary job. The primary job is the company's climate, its retention rate, its promotion and school pipeline, and the FA battalion commander's trust in your ability to run the orderly room with zero fraudulent actions, zero integrity incidents, and zero administrative backlogs. The TA platoon sergeant who was technically excellent but organizationally loose — counseling not documented, supply accountability deferred, family readiness thin — does not succeed as FA HHB 1SG. The 1SG seat requires organizational precision that the platoon sergeant built or did not build while she had the smaller scope. The CSM track begins at 1SG with the USASMA conversation. The FA branch sends its best 1SGs to USASMA for the Senior Leader Course or the resident Sergeants Major Course; the 1SG who has MLC complete, clean NCOERs, and a battalion commander who believes in her candidacy gets nominated. The CSM track is a ten-year journey from SFC pin-on; the SFC who understands the gates — MLC, USASMA, 1SG, CSM — and starts preparing for each two years before she needs to be competitive is the SFC who makes it without being surprised by any of them.
FAQ

13R E7 — Frequently Asked Questions

Q01What does a E7 13R (Field Artillery (FA) Weapons Locating Radar (WLR) Specialist) actually do?
You run the TA platoon's enlisted side — training, evaluations, schools, promotions, discipline, equipment readiness, and family readiness.
Q02What's the most important thing to know as a E7 13R?

Q03What does a typical day look like for a E7 13R?
Time-blocked day at the E7 13R rank tier: 0530 PT formation. You run with the platoon but the section NCOs lead their sections. You are observing the section NCO who you are counseling this week on ACFT event weaknesses — you noted it in his counseling draft yesterday, 0630–0700 Shower, change, chow, 0730 Platoon accountability and section NCO check-in.

The honest pathway: tell the battalion CSM directly that you are interested in the 1SG track, ask what she sees in your record that is not yet competitive,…
