Tracked Vehicle Repairer

E-5 (Sergeant) · Army

E1–E3E-4E-5E-6E-7E8–E9
HEADS UP

ALC is the gate to SSG. But the section you run right now — its OR rate, its MRO closure quality, its CMDP inspection readiness, and the soldiers you are training — is what the company commander and maintenance control sergeant are watching when the ALC slate conversation starts. The OR rate is your NCOER bullet.

The Honest MOS Read
You run a 3-5 soldier tracked-vehicle section inside an FSC, a BSB maintenance company, or a brigade-level shop aligned to a specific platform family. The section is yours in a way the wrench team was not at E-4 — you sign the hand receipt, you write the counselings, you brief the production meeting, and when the dispatch board shows a red vehicle, the FSC commander looks at you for the root cause. The daily split at SGT 91H is roughly 60% leadership and 40% wrenching. You still diagnose the hard faults — the ones that stumped the SPC — but more of your time goes to managing the section's MRO queue in GCSS-Army, reviewing DA 5988-E entries for accuracy, scheduling services around the training calendar, and running the Class IX demand history that tells the brigade S4 what you need before he is surprised on the readiness slide. You conduct quarterly CMDP (Command Maintenance Discipline Program) inspections at the section level and the results tell the maintenance control sergeant whether your shop is ready for the brigade-level inspection or needs remediation. BDAR — Battle Damage Assessment and Repair — becomes your signature field skill. In garrison you run scheduled services and deliberate repairs. In the field, at a CTC rotation or deployment, you run contact-team maintenance at the logistics release point: a Bradley or M109 Paladin rolls in with a battlefield fault, you assess whether it can be repaired forward with field-expedient methods or whether it needs evacuation to the BSB. BDAR is the skill that keeps the combined-arms battalion in the fight when the parts pipeline cannot keep up. The 91H SGT who can run a BDAR assessment on a Bradley and get it back to the line in 4 hours instead of evacuating it for 48 hours of BSB-level repair is the one the maneuver battalion remembers. The OR (Operational Readiness) rate is the metric that defines your section's contribution to the brigade. You learn to defend it: why a vehicle is deadline, what the recovery plan is, when the Class IX part is arriving, what the projected return-to-FMC date is. The FSC commander takes this data to the BSB commander; the BSB commander takes it to the BCT commander. If your numbers are wrong, the slide is wrong, and the trust chain breaks from your section upward. The NCOER at E-5 is the first evaluation that truly shapes your career. Your rater is the company maintenance officer or the FSC commander; your senior rater is the BSB commander or the battalion XO. The bullets that matter: OR rate maintained, MROs closed on time, CMDP findings closed, soldiers trained and certified, BDAR operations conducted at CTC. Write your own bullets in draft before the rating period closes — the rater uses your input even if he does not say so.
Career Arc
  • 01ALC (Advanced Leader Course) — the gate to SSG. Prerequisite: BLC graduate, SGT, time-in-grade, and the company commander's recommendation.
  • 02First NCOER as a rated SGT — the evaluation that starts shaping your career trajectory toward SSG or career plateau.
  • 03BDAR course completion if not already done — this is the field-maintenance qualification that makes your section CTC-rotation-ready.
  • 04CMDP inspection experience at the section level — running your own section through a quarterly inspection trains you for the company-level inspections you will own as SSG.
  • 05First CTC rotation as a section NCOIC — the defining field event that proves whether your section can sustain a tracked fleet under operational conditions.
  • 06915A Warrant Officer packet preparation begins in earnest — technical depth, chain-of-command letters, operational experience.
  • 07SLC packet preparation — the Senior Leader Course is the gate to SFC and must be on the bench by the time the E-6 board convenes.
Common Screwups
  • ×DUI at the SGT level — the career impact is worse than at E-4 because you are now a rated NCO with subordinates who watched it happen. The company commander's options narrow; the NCOER reflects it; the ALC slate is off the table.
  • ×NCOER neglect — failing to counsel subordinates monthly, failing to document MRO closure rates and OR rate trends, then scrambling to write NCOER bullets at the end of the rating period. The rater notices the gap and the evaluation shows it.
  • ×ACFT failure at the SGT level — flagging blocks ALC, blocks favorable actions, and sends a message to your section that the NCO does not hold himself to the standard he enforces on them.
  • ×SHARP / EO incident — as a section NCOIC you are responsible for the climate in your section. One substantiated complaint rewrites your NCOER and closes the SSG door.
  • ×Financial mismanagement that triggers command involvement — garnishments, collection calls to the 1SG, debt spirals. The command climate survey flags it and the 1SG counseling trail follows you to the next unit.

A Day in the Life

  • 0500Wake up. Check your phone for overnight messages from the company — vehicle faults reported, parts received, training changes.
  • 0530PT formation. You form your section. Accountability is your responsibility — you know who is present, who is on profile, who is on leave before the platoon sergeant asks.
  • 0600-0700Unit PT. You run with the section or break out for the platoon's strength program. You monitor your soldiers' fitness and adjust individual guidance for the next ACFT.
  • 0700-0900Hygiene, breakfast, uniform change. You log into GCSS-Army and run the daily MRO status report for your section. You review the dispatch board for today's vehicle movements and identify which vehicles need pre-dispatch PMCS.
  • 0900First formation in the motor pool. You brief your section on the day's vehicle assignments, MRO priorities, and any brigade-directed maintenance actions.
  • 0915-1130Bay production. Your SPCs and PVTs are on assigned vehicles. You walk the floor: check PMCS quality, review MRO progress, assist on diagnostic leads when the SPC hits a wall. You spend 30 minutes updating GCSS-Army — MRO status codes, parts receipt, scheduled services.
  • 1130-1300Chow. You release the section to the DFAC. You use 15 minutes to prepare your notes for the company production meeting if it is scheduled for today.
  • 1300-1400Company production meeting (typically Mon/Wed) — you brief your section's tracked sub-fleet: OR rate, open MROs, deadline-aged vehicles, parts on order, projected return-to-FMC dates. The FSC commander asks questions; you have the answers.
  • 1400-1600Afternoon bay production or training. Sergeant's Time Training on STP 9-91H14 tasks, BDAR rehearsals, M88A2 cross-training, counseling sessions with soldiers due for monthly counseling.
  • 1600-1630Tool accountability, shop cleanup, final GCSS-Army updates. Section NCO final walk of the bay floor.
  • 1630Final formation. You brief tomorrow's plan to your section. Release — unless a deadline vehicle that must dispatch tomorrow keeps the section late.
  • 1700-2100Personal time. NCO development: ALC prep, SLC correspondence, ASE certification study, NCOER draft writing. The SGTs who make SSG are the ones who treat this block as professional development, not downtime.
  • Field rotationYou are at the logistics release point or the maintenance collection point. Your section runs contact-team maintenance on every tracked vehicle that comes in with a battlefield fault. You make the repair-or-evacuate decision. You run the M88A2 recovery if a Bradley throws a track in the wire. You brief the FSC commander on your section's status every 12 hours. Sleep is 4-6 hours between BDAR assessments.

Weekly Cadence

Monday: company production meeting sets the week. You brief your section's tracked sub-fleet status — OR rate, open MROs, deadline-aged vehicles, parts on order. The FSC commander's questions tell you what the BSB commander is asking. Monday afternoon is bay production: clearing the weekend backlog, starting new MROs on faults discovered during Friday's final PMCS. Tuesday through Thursday: the production core. Your SPCs and PVTs are on assigned vehicles running diagnostic and repair work. You walk the floor, supervise quality, and pull yourself onto the hardest diagnostic fault in the section when needed. Sergeant's Time Training runs mid-week — you plan the training around STP 9-91H14 tasks and the section's skill gaps. Wednesday is typically the day you run monthly counseling sessions with each soldier in the section. Thursday afternoon is often mandatory training (SHARP, EO, ATFP, safety), which cuts bay time — plan your section's production knowing half of Thursday is lost. Friday: weekly closeout. GCSS-Army MRO queue review, CMDP self-inspection items, tool inventory, shop cleanup. You review the week's metrics: MROs opened and closed, parts ordered and received, deadline days accumulated, OR rate trend. The maintenance control sergeant may walk the floor Friday afternoon — have the bay clean and the data ready. Release depends on whether the dispatch board is green for Monday and whether the section's CMDP items are current.

Key Skills — How to Drill Each

  1. 01
    Build and defend a section maintenance production schedule — green/amber/red across the tracked sub-fleet, with realistic mechanic-hours and Class IX float.
    Start with the GCSS-Army data: open MROs, parts on order, scheduled services due, deadline-aged vehicles. Map each vehicle to a recovery plan with a projected return-to-FMC date. Brief the plan at the company production meeting with enough detail that the FSC commander can defend it at the BSB meeting. The section NCO who shows up without a timeline gets asked 'when?' and has no answer — the one who shows up with a 30/60/90 outlook earns the commander's trust.
  2. 02
    Run a section through a field-maintenance package at NTC/JRTC — contact teams, BDAR, M88A2 HERCULES recovery operations.
    The CTC rotation is where garrison maintenance meets operational reality. Your contact team deploys to the logistics release point with tools, TMs, a GCSS-Army laptop, and the authority to make repair-or-evacuate decisions under time pressure. Rehearse the contact-team SOP before the rotation: who carries what tools, who runs the HERCULES, who communicates with the combined-arms battalion, who manages the MRO queue. The section that has rehearsed runs smooth; the section that wings it loses vehicles to unnecessary evacuation.
  3. 03
    Conduct quarterly CMDP inspections at the section level — paperwork, equipment, accountability, training records.
    CMDP is the Army's maintenance quality-assurance program. At the section level, you inspect: DA 5988-Es for completeness and accuracy, TMDE calibration status, hand-receipt accountability, training records (STP task completion, BDAR qualification), shop safety compliance. Document everything. The findings you catch and correct at the section level are the findings the brigade IG does not catch at the brigade level.
  4. 04
    Sign and defend a sub-hand receipt for TMDE, shop sets, and tracked Class VII end items.
    The hand receipt is your accountability document. Quarterly inventories are not optional — they are the proof that every piece of TMDE, every shop-set component, and every Class VII end item is where the Army says it is. The shortage annex must be current and the explanation for every shortage must be documented. The CSM who walks your shop and finds an item missing that is not on the shortage annex starts the conversation nobody wants to have.
  5. 05
    Operate GCSS-Army at the section NCO level — open/monitor/close MROs, run section readiness reports, defend the Class IX demand history.
    The Class IX demand history is the data trail that tells the brigade S4 what your section needs and how fast you use it. A clean demand history means accurate parts forecasting; a dirty one means you are always surprised when the part you needed three weeks ago has not arrived. Run the demand-history report monthly, reconcile it with your open MROs, and brief the discrepancies to the company maintenance officer.
  6. 06
    Mentor privates and specialists on diagnosis-not-replacement — if they leave your section as parts-changers, that failure is yours.
    Schedule one Sergeant's Time Training session per week focused on a specific diagnostic procedure: hydraulic pressure testing, electrical troubleshooting, engine-performance analysis. Use a real vehicle with a real fault — not a classroom scenario. Walk the soldier through the TM troubleshooting tree, then let him diagnose the next one independently. Review his MRO fault description. The section whose MRO fault descriptions are precise and diagnostic is the section whose SGT is training his people.

Manuals & References — What Chapters Matter

  • AR 750-1 — Army Materiel Maintenance Policy; AR 710-2 — Supply Policy Below the National Level.
    AR 750-1 governs the entire maintenance system you operate in — from PMCS to depot repair, from CMDP inspections to OR-rate reporting. AR 710-2 governs the supply system that feeds your Class IX requisitions. Read the chapters on field maintenance, hand-receipt procedures, and controlled exchange before your first CMDP inspection as section NCOIC.
  • AR 700-138 — Army Logistics Readiness and Sustainability.
    This regulation governs the readiness reporting that your OR rate feeds into. Understanding how your section's data rolls up to brigade and division readiness reporting helps you anticipate the questions the FSC commander will get — and prepare answers before he asks you.
  • DA PAM 750-1 — Commander's Maintenance Handbook; DA PAM 750-3 — Field Maintenance Operations.
    DA PAM 750-1 is the commander's perspective on maintenance; DA PAM 750-3 is the field operations guide. Together they explain the contact-team mission set you execute at CTC rotations — how maintenance support flows from the FSC to the combined-arms battalion, how BDAR decisions are made, and how evacuation priorities are set.
  • AR 623-3 — NCOER; AR 600-8-19 — Enlisted Promotions.
    You write NCOERs now — on your SPC and your CPL. AR 623-3 governs the evaluation system; DA PAM 623-3 has the practical guidance on bullet writing. AR 600-8-19 governs the promotion system your soldiers are trying to navigate. Read both so you can counsel your subordinates accurately on what the promotion board sees.
  • ATP 4-90 — Brigade Support Battalion; ATP 4-33 — Maintenance Operations.
    ATP 4-90 is your formation's doctrinal reference — the BSB's mission, organization, and maintenance-support concept. ATP 4-33 covers maintenance operations doctrine: contact maintenance, backup maintenance, BDAR, recovery operations. Read ATP 4-33 before your first CTC rotation as a section NCOIC.
  • TC 7-22.7 — The Army NCO Guide; ADP 6-22 — Army Leadership.
    TC 7-22.7 is the NCO's professional reference — duties, responsibilities, authority, and the NCO Creed in practice. ADP 6-22 is the leadership doctrine the Army expects you to embody. Read both early in your SGT tenure; the maintenance world values technical competence, but the Army evaluates NCOs on leadership as much as skill.

Standards — How to Hit Each

  • ALC graduate within the window — SLC packet on the bench when E-6 enters the conversation.
    ALC is allocated by the branch and the unit. Your job is to be eligible and competitive when the slot opens. Eligibility: BLC graduate, SGT, required TIG. Competitiveness: NCOER profile, weapons qual, ACFT score, military education, civilian education, awards. Start SLC packet preparation while at ALC — the lag between ALC graduation and the E-6 board is shorter than you think.
  • BDAR course complete before leading a section on its first CTC rotation.
    BDAR teaches field-expedient repair when the parts pipeline cannot keep up. The course covers assessment methodology, repair techniques using non-standard materials, and the decision framework for repair-forward vs. evacuate. Complete it before the CTC rotation because the OC/T evaluates your BDAR decisions during the rotation — the section NCOIC who does not know BDAR methodology makes evacuation decisions that hurt the combined-arms battalion's combat power.
  • Section OR rate at or above the company average; CMDP inspection finding rate trending down quarter-over-quarter.
    OR rate is the number the FSC commander briefs. CMDP finding rate is the number the maintenance control sergeant watches. Both improve when you do the fundamentals: accurate PMCS, correct diagnosis on the first attempt, timely parts requisitions, complete MRO documentation. Track both metrics monthly and address trends before they become briefing-slide problems.
  • NCOERs written in measurable, defensible bullets — Class IX dollar flow, OR rate, MRO closure, soldiers trained and certified.
    Start your NCOER support form on day one of the rating period. Track your section's metrics monthly: OR rate, MRO closure rate, Class IX expenditure, CMDP findings, soldiers trained on STP tasks, soldiers sent to schools. These become your NCOER bullets. The rater who receives a support form with concrete numbers writes a stronger evaluation than the one who receives 'maintained tracked vehicles.'
  • ACFT 540+ at this rank; section fitness on the company-level slide.
    The section NCO's fitness sets the floor for the section. If your ACFT is 490 and you are counseling a SPC on his 475, the conversation has no authority. Hit 540+ and maintain it. Run with your section during PT; the soldiers who see their SGT finishing ahead of them respect the standard.

Technical Mistakes — Concrete Consequences

  • Counseling soldiers verbally without documentation.
    The relief-for-cause is on you when the company commander asks why a soldier was relieved without a paper trail. Monthly counseling per AR 623-3 / TC 7-22.7 is not optional — it is the documentation that protects the soldier, protects you, and protects the chain of command.
  • Signing the dispatch on a tracked vehicle your private closed in GCSS-Army without your section road test.
    The deadline on the road march is on your name. The dispatch authority means you certified the vehicle as mission-capable. If the private's repair was incomplete and the vehicle breaks down in the box at NTC, the OC/T's after-action traces the dispatch signature back to you.
  • Hiding a CMDP shortcoming from the maintenance control sergeant to fix it before the inspection.
    The IG finds it and the company eats a finding. The maintenance control sergeant who discovers you hid the shortcoming loses trust in your reporting — and that trust gap follows you through every production meeting for the rest of the rating period.
  • Letting a specialist run diagnostic lead on a tracked system he is not trained on because 'he is sharp.'
    The misdiagnosis destroys a component and the bill is five figures. Sharp is not the same as trained. The SPC who has never done a turret-drive pressure test should not be running one unsupervised because you were too busy to walk it. The training gap is your responsibility.
  • Skipping the GCSS-Army demand history before the brigade S4 asks.
    The OR slide goes up without context. The FSC commander cannot defend the Class IX float at the BSB meeting. The BSB commander asks why the FSC's tracked OR rate dropped and nobody in the room has the data. Your section's credibility in the readiness-reporting chain degrades, and rebuilding it takes a full quarter.

Career Decisions at This Rank

  • ALC timing and SSG board preparation.
    ALC is branch-allocated and unit-recommended. Your NCOER profile, ACFT score, military education, and civilian education all factor into the board. Start civilian education now — even a few credit hours toward a degree add points. The soldiers who pin SSG at the first look are the ones who started preparing at SGT, not the ones who scrambled after ALC graduation.
  • 915A Warrant Officer Maintenance Technician packet.
    The 915A pipeline is the highest-value career move for a technically gifted 91H. The packet requires chain-of-command recommendation, a technical-depth portfolio, and a board appearance. Start building the portfolio now: TMDE accountability records, MRO quality metrics, BDAR qualification, M88A2 proficiency, ASE certifications. The warrant board looks for technical depth that exceeds NCO-level expectations — your diagnostic accuracy and your ability to manage a production floor are the differentiators.
  • Stay line unit vs. schoolhouse / TRADOC assignment.
    Instructor duty at the 91H AIT schoolhouse or at the Ordnance School gives you a break from the FSC/BSB OPTEMPO and builds your teaching skills — which matter at SSG and above. The downside: you lose 2-3 years of operational NCOER bullets in a line unit. The board values both but weights operational NCOERs more heavily. If you choose the schoolhouse, go with a plan to return to a line unit before the SSG board.
  • Re-enlistment for a specific duty station or stabilization.
    At E-5 your re-enlistment options include duty-station-of-choice, stabilization at current duty station, and unit-of-choice. If you are at an ABCT and want to stay in the tracked world, stabilize. If you want OCONUS experience (Korea, Germany, Kuwait rotation), request it — overseas NCOERs carry weight at the board and the maintenance experience in deployed/forward conditions is genuine professional development.
  • Degree completion — associate's or bachelor's while serving.
    Tuition Assistance pays for college courses while you are in. At E-5 the time pressure is real — bay production, counselings, NCOERs, training calendar — but the soldiers who make SSG and SFC with a degree have a measurable advantage at promotion boards and in the post-service job market. Start with an associate's in a technical field (industrial maintenance, diesel technology, engineering technology) and build from there. Online programs through accredited schools work around the military schedule.

How the Seat Varies by Unit Type

  • ABCT FSC — supporting a combined-arms battalion
    This is the section NCOIC's proving ground. You own a sub-fleet of 10-14 Bradleys plus M113 variants, and the combined-arms battalion commander knows your section's OR rate by name. At NTC your contact team is the forward maintenance presence — every BDAR decision you make directly affects the battalion's combat power. The FSC commander rates you; the BSB commander senior-rates you. Your NCOER bullets come from operational readiness, not classroom metrics.
  • BSB maintenance company — brigade consolidated shop
    In the BSB you see vehicles from across the brigade. The shop foreman (SSG) runs the production floor; you run a section within it. The advantage: broader platform exposure and more complex diagnostic challenges. The disadvantage: you do not own the relationship with a single battalion's operators the way the FSC section NCOIC does. Your NCOER bullets come from production metrics — MRO closure rate, Class IX expenditure, CMDP inspection performance.
  • NTC / JRTC observer-controller / trainer (OC/T) support
    Some SGTs are assigned to CTC support units that maintain the OPFOR or exercise-support tracked fleet. The work is steady, the platforms are known, and the rotation cycle is predictable. The NCOER is different — you are evaluated on training support, not on a line unit's OR rate. This is a broadening assignment; do not stay more than one rating period if SSG is the goal.
  • Division or corps-level maintenance (sustainment brigade)
    Sustainment brigades operate at echelons above the BCT — you may be doing reset maintenance on tracked vehicles returning from deployment or supporting pre-positioned stock. The diagnostic challenges are deeper (depot-level faults), the pace is more deliberate, and the skill development in heavy repair is excellent. The NCOER disadvantage: sustainment-brigade NCOERs compete against FSC/BSB NCOERs at the SSG board, and the board values operational-unit bullets.
  • SFAB (Security Force Assistance Brigade)
    SFABs advise partner-nation militaries on their maintenance programs. If the partner nation fields tracked vehicles, a 91H SGT with diagnostic expertise and the ability to teach is valuable. The work is more advisory than hands-on. The NCOER is different — you are evaluated on advisor effectiveness, not OR rate. This is a broadening assignment with real operational value, but it takes you out of the direct maintenance chain for a rating period.

What Good Looks Like at This Rank

The good SGT 91H runs a section whose OR rate the FSC commander names in the slide without surprise. His soldiers close MROs cleanly — the fault descriptions are precise, the diagnostic traces are documented, the parts requisitions are correct on the first submission. His ALC graduates show up on the SSG board with measurable NCOER bullets because he tracked the metrics and provided the data. The brigade S4 trusts his Class IX demand history because it has been accurate for three consecutive quarters. The maintenance control sergeant sends him to the hardest CMDP inspection because his section passes, and the findings he does receive are documented, closed, and tracked before the next quarterly review. The brigade S3 is already asking whether this section is going to be the CTC rotation anchor, because a tracked-vehicle section that runs clean is rare and the brigade does not give up rare lightly. The difference between the good SGT and the average SGT is not diagnostic skill — it is leadership discipline. The good SGT counsels monthly, tracks metrics weekly, runs Sergeant's Time Training on STP tasks every week, and builds his soldiers' diagnostic capability deliberately. The average SGT fixes the vehicle himself because it is faster, skips the counseling because it is easier, and arrives at the NCOER with nothing to write because he never tracked anything. The section's OR rate tells the story either way.

Preview — The Next Rank

At E-6 (SSG), you stop running a section and start running the shop. You are the shop foreman of a BSB tracked-vehicle section or the maintenance control NCO for an FSC — managing 10-20 mechanics across multiple platforms. You build the company's quarterly maintenance training brief, run the GCSS-Army production board for the tracked fleet, and sit in the brigade maintenance synchronization meeting as the senior 91H voice. The 915A Warrant Officer Maintenance Technician pipeline becomes a real conversation at E-6. The packet is competitive and the schoolhouse has real academic and technical requirements, but the SSG who has been building the portfolio since E-4 — diagnostic accuracy, TMDE management, BDAR qualification, production-floor leadership — is the one who walks into the board interview with substance instead of ambition. The honest weight of E-6: the BSB commander asks why a battalion's tracked OR rate is red, and you are the NCO who has the root cause and the recovery timeline — not the NCO who passes the question to the lieutenant. You translate maintenance risk into language the commander can defend at brigade. If you cannot do that, the shop runs on the lieutenant's best guess instead of the NCO's ground truth.
