Tracked Vehicle Repairer

You are the newest wrench in the track bay. The Bradley that has to roll for gunnery at 0500 does not care that you are tired — it cares whether you checked the track tension, serviced the torsion bars, and signed the -10 block.

You finished roughly 13 weeks of AIT at Fort Jackson, South Carolina, and now you live in the motor pool. You pull preventive maintenance checks and services (PMCS) on M2/M3 Bradleys, M113-family APCs, M109-series Paladins, and — if the unit owns one — the M88A2 HERCULES recovery vehicle. You learn what "deadlined" means on a tracked platform by feeling it: a thrown track pin, a broken road-wheel arm, a leaking final drive. You grease every fitting, check every fluid, and track (pun intended) every fault on a DA Form 5988-E before the operator can dispatch. You spend half your day under vehicles; the other half is chasing Class IX parts the brigade does not have, opening MROs in GCSS-Army with help from the section corporal, and listening very carefully to the senior 91H before you touch the next component.

• 01Run a complete operator-and-crew PMCS (before, during, after) on an M2/M3 Bradley per TM 9-2350-294 series — find the deadline fault before the dispatch.
• 02Adjust and replace track on an M113 or Bradley — pad removal, pin extraction, master pin installation, tension adjustment to TM specification.
• 03Service the Bradley's CUMMINS VTA-903T diesel to the TM 9-2815 series schedule — fluids, filters, belts, coolant concentration, with the -20P parts manual open.
• 04Inspect, replace, and service road wheels, return rollers, and torsion-bar suspension components on the M113 / Bradley running gear.
• 05Open and close a GCSS-Army Maintenance Request Order (MRO) cleanly under supervision — fault description, parts requisitioned, labor hours, status code, operator signature.
• 06Use a torque wrench, a multimeter, and a hydraulic pressure gauge correctly — the senior mechanic should not have to take it out of your hand.

• —TM 9-2350-294-10 series — M2/M3 Bradley operator manual (the manual you will reference daily on the shop floor).
• —TM 9-2350-261-20 series — M113-family armored personnel carrier unit maintenance.
• —TM 9-2350-314-10 series — M109A6/A7 Paladin SPH operator manual.
• —TM 9-2815 series — diesel engine maintenance covering the powerplants across your tracked fleet.
• —DA PAM 750-8 — The Army Maintenance Management System (TAMMS) User Manual.
• —STP 9-91H14-SM-TG — Soldier's Manual and Trainer's Guide, MOS 91H, skill levels 1-4.

• —PMCS deadline-fault discovery rate that matches the senior mechanic's — if you are missing what he catches, you are not learning the platform.
• —91H Sustainment Skills Validation passed annually, on the first attempt.
• —ACFT 500+ — tracked vehicle bays are physical environments and the section PT standard is not optional.
• —Driver/operator qualification (OF 346) on the M113 and Bradley as the unit requires — you cannot PMCS what you have never moved.
• —DA 5988-E entries legible, complete, and accurate — sloppy fault descriptions generate wrong parts orders and the unit waits.

• —Faking a PMCS. The Bradley that "passed" yesterday will deadline at gunnery and the platoon sergeant will pull your dispatch book in front of the company.
• —Adjusting track tension by eye instead of by the TM measurement procedure. Incorrect tension wears pads early, throws pins on turns, and puts the vehicle down mid-exercise.
• —Leaving a removed component — road wheel, return roller, idler — on the ground behind a vehicle and not accounting for it before the next movement. Somebody drives over it.
• —Closing an MRO in GCSS-Army before the replaced part is actually installed and the vehicle road-tested. The next inspection finds it and the company maintenance officer eats it with you in the room.
• —Using the wrong fluid or lubricant — wrong engine oil weight, wrong gear oil for the final drives, wrong hydraulic fluid for the ramp/turret systems. The bill goes to the unit and your name is on the MRO.

The good cherry 91H is the soldier the bay chief sends to the deadline Bradley at 1630 on a Friday because it will come back signed off and ready for the dispatch board Monday morning. By month nine he closes MROs cleanly under supervision; by month eighteen he knows the Bradley's running-gear fault signatures by the sound and has the section NCO asking whether he wants the Recovery vehicle cross-qualification or the BDAR course first.

You are the bay's working brain on a tracked platform. You inherit the deadline fault that has stumped two privates and the new lieutenant who keeps signing for a Bradley he cannot turn over.

You run a 2-3 soldier wrench team on a specific tracked platform family — Bradley IFV, M113/M113A3, M109 Paladin, or M88A2 HERCULES. You diagnose, you do not just replace. You walk a private through a hydraulic system leak-down test and you tell an operator why his neutral-steer complaint is a steering mechanism issue and not a transmission problem. You sign for Test, Measurement, and Diagnostic Equipment (TMDE) and you treat it like the calibrated, expensive gear it is. You are running MROs in GCSS-Army for your sub-section and you actually know which Class IX parts the brigade S4 has on the shelf versus the ones tracking through TACOM. The M88A2 HERCULES is the recovery platform the rest of the company calls when a Bradley throws a track in a berm — you want to be the 91H who knows how to run that machine.

• 01Diagnose a power-loss, overheating, or hydraulic fault across the tracked fleet without throwing parts at it — pressure tests, voltage drops, coolant chemistry, fluid sample analysis before the parts requisition.
• 02Perform a Bradley / M113 final-drive service and road-test to TM standard — fluid, magnetic drain plug inspection, gasket, seal condition, all the way to the post-service test drive.
• 03Operate the M88A2 HERCULES recovery vehicle under supervision — winch operations, boom employment, tow/haul-mode selection, rigging safety brief.
• 04Use TMDE per AR 750-43 — torque-wrench certification cycles, pressure-gauge cert, multimeter calibration, all tracked through the unit's TMDE Support Center.
• 05Run GCSS-Army at the sub-section level — open/monitor/close MROs, manage the work-order queue, run the Maintenance Master Driver Reports.
• 06Train new privates on PMCS by walking the vehicle and pointing at what they missed — not by lecture.

• —BLC graduate; promotion points stacked with weapons quals, schools, and Army Credentialing Assistance-funded trade certifications.
• —Sub-section MRO closure rate at or above 90% within the published window; deadline-fault first-time-fix rate measurable and trending up.
• —Zero TMDE calibration lapses on the gear you sign for. One out-of-cal torque wrench in a sustainment inspection eats the section's afternoon.
• —M88A2 operator qualification on the OF 346 if the unit owns HERCULES — the company has no use for a 91H who cannot run its recovery asset.
• —ACFT 540+ minimum — the track bay is not a gym excuse, and the section NCO's fitness standard is yours to meet.

• —Throwing parts at a tracked-vehicle diagnosis. Three swapped final-drive seal kits in a week and the company maintenance officer asks why a SPC is the one ordering Class IX without a diagnostic trace.
• —Cannibalizing components across tracked vehicles without an authorized controlled-exchange document. The CSM finds the un-papered swap during a walk-through and the company eats a relief-for-cause counseling.
• —Closing MROs in GCSS-Army before the road test on a tracked vehicle. A Bradley with an improperly seated final drive comes back on the flatbed — and you spend a weekend with your name on it.
• —Rigging the M88A2 for a recovery without the proper weight-class brief and TM-specified rigging procedure. A field recovery gone wrong with the HERCULES is a SIGACT, a safety report, and a CID investigation simultaneously.
• —Letting TMDE cycle out of calibration. Every torque reading you took with that wrench is now suspect, which means every flange on every tracked vehicle you serviced in the last 90 days is suspect.

The good Specialist 91H is the mechanic the platoon sergeant sends to the deadline Bradley that has eaten two cherries and a senior mechanic, because it will come back diagnosed, repaired, road-tested, and closed in GCSS-Army before the BUB. He knows the Bradley's fault signatures before he pulls the TM, the bay chief is fighting to keep him on the BLC slate, and the contractor at the FOB already asked if he is ETSing.

You are an NCO now and you run a tracked-vehicle section. The maintenance control sergeant is mentoring you, the FSC commander is leaning on you, and the dispatch book on every Bradley, Paladin, or M88 you own is yours to defend.

You run a 3-5 soldier section inside an FSC, a BSB maintenance company, or a brigade-level shop aligned to a specific tracked platform family. You write counseling statements on the 14th, you build the section's training calendar around the platform you own, and you brief your sub-fleet's maintenance status at the company production meeting. You sign for tens to hundreds of thousands of dollars in TMDE, Class VII end items, and shop stock. In the field you are at the FSC logistics release point running contact-team maintenance on a Bradley or M109 Paladin that took a battlefield fault mid-rotation; in garrison you are in the bay, writing NCOERs, pushing soldiers through the BDAR course and BLC packets, and building the section's Class IX demand history so the brigade S4 is not surprised on the readiness slide.

• 01Build and defend a section maintenance production schedule — green/amber/red across the tracked sub-fleet, with realistic mechanic-hours and Class IX float.
• 02Run a section through a field-maintenance package at NTC / JRTC — contact teams, BDAR, M88A2 HERCULES recovery operations, the full field-maintenance-company mission set.
• 03Conduct quarterly Command Maintenance Discipline Program (CMDP) inspections at the section level — paperwork, equipment, accountability, training records, all defensible.
• 04Sign and defend a sub-hand receipt for TMDE, shop sets, and tracked Class VII end items — quarterly inventories on time, shortage annexes clean.
• 05Operate GCSS-Army at the section NCO level — open/monitor/close MROs, run section readiness reports, defend the Class IX demand history.
• 06Mentor privates and specialists on diagnosis-not-replacement. If they leave your section as parts-changers, that failure is yours.

• —AR 750-1 — Army Materiel Maintenance Policy; AR 710-2 — Supply Policy Below the National Level.
• —AR 700-138 — Army Logistics Readiness and Sustainability (the readiness reporting reg you live under).
• —DA PAM 750-1 — Commander's Maintenance Handbook; DA PAM 750-3 — Field Maintenance Operations.

• —Section operational readiness (OR) rate at or above the company average; CMDP inspection finding rate trending down quarter-over-quarter.
• —NCOERs written in measurable, defensible bullets — Class IX dollar flow managed, OR rate, MRO closure, soldiers trained and certified.
• —ACFT 540+ at this rank; section fitness on the company-level slide.

• —Counseling soldiers verbally. The relief-for-cause is on you when the company commander asks why a soldier was relieved without a paper trail.
• —Signing the dispatch on a tracked vehicle your private closed in GCSS-Army without your sub-section road test. The deadline on the road march is on your name.
• —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.
• —Letting a specialist run diagnostic lead on a tracked system — hydraulic ramp, turret drive, fire-control interface — he is not trained on because "he is sharp." The misdiagnosis destroys a component and the bill is five figures.
• —Skipping the GCSS-Army demand history before the brigade S4 asks. The OR slide goes up without context and the FSC commander cannot defend the float.

The good SGT 91H runs a section whose OR rate the FSC commander names in the slide without surprise. His soldiers close MROs cleanly, his ALC graduates show up on the SSG board with measurable bullets, and the brigade S4 trusts his Class IX demand history. The brigade S3 is already asking whether this section is going to be the CTC rotation anchor, and the maintenance control sergeant is fighting to keep him on the SLC slate because a tracked-vehicle section that runs clean is rare and the brigade does not give up rare lightly.

The track shop is yours. The maintenance control officer signs; you run the production floor. If a Bradley or Paladin goes red on the brigade readiness slide, the first question the BSB commander asks is why you did not call it two days ago.

You are the maintenance control NCO for an FSC or the shop foreman of a BSB tracked-vehicle section — managing 10-20 mechanics across multiple platforms: Bradley IFVs, M113 APCs, M109 Paladins, and M88A2 HERCULES recovery assets. You build the company's quarterly maintenance training brief input and run the GCSS-Army production board for your fleet: open work orders, parts on order, scheduled services, deadline-aged reports, and the brigade readiness rollup. You sit in the brigade maintenance synchronization meeting as the senior 91H voice. When the BSB commander asks why a battalion's tracked OR rate is red, you are the NCO who has the root cause and the recovery timeline — not a shrug.

• 01Run a GCSS-Army production board at the company level for a mixed tracked fleet — load-leveling mechanics, parts triage, scheduled services versus surge demand, with a defensible 30/60/90 outlook.
• 02Build a Quarterly Training Brief (QTB) input that aligns mechanics with platform sustainment training, BDAR qualification, and the brigade's deployment cycle.
• 03Defend a Command Maintenance Discipline Program (CMDP) inspection at the company level — documentation trail, training records, TMDE calibration, shop safety, all clean.
• 04Lead a brigade-level tracked recovery and BDAR rehearsal — M88A2 HERCULES employment, towing/hauling decisions, controlled-exchange authority, all rehearsed before the CTC rotation.
• 05Mentor section sergeants into shop-foreman-ready candidates without losing your own SLC bench position.
• 06Translate maintenance risk into language the FSC / BSB commander can defend at brigade — OR trend, parts-on-order aging, mechanic-hours available versus required.

• —AR 750-1 — Army Materiel Maintenance Policy; AR 710-2 — Supply Policy.
• —AR 700-138 — Army Logistics Readiness and Sustainability (your readiness reporting reg).
• —DA PAM 750-1 — Commander's Maintenance Handbook; DA PAM 750-3 — Field Maintenance Operations.
• —AR 623-3 + DA PAM 623-3 — NCOER (you write SGT-level evaluations now).
• —ATP 4-90 — Brigade Support Battalion; ATP 4-33 — Maintenance Operations.
• —TM 9-2350-358-10/20 series — M88A2 HERCULES operator and unit maintenance (your recovery platform; own this).

• —SLC graduate; MLC packet built; the Maintenance Senior Sergeants Course at Fort Gregg-Adams as a differentiator.
• —BDAR instructor qualification or recognized subject-matter expert on the tracked platform the unit fields.
• —Company-level tracked OR rate at or above the brigade average over rolling quarters; deadline-aged-over-30-day count trending down.
• —CMDP inspection findings at the company level closed before the next quarterly review.
• —NCOER profile defensible at brigade — Top Block / Most Qualified rate matching the actual quality delta in soldiers selected.

• —Inflating the GCSS-Army OR rate by sliding tracked deadline-faults into "scheduled services" lanes. The brigade S4 sees the demand history and the maintenance control officer eats it with you in the room.
• —Skipping the Class IX demand-history review before the brigade synch. The FSC commander shows up to the meeting without the data and the BSB commander asks why his shop foreman did not prep him.
• —Confusing field-maintenance expertise with sustainment-level expertise on tracked platforms. The transition from field to depot-level tracked work requires honesty about where your authority ends and where TACOM/ANAD picks up.
• —Authorizing a controlled exchange on a tracked component without the paperwork because "we will catch it Monday." The CSM finds the un-papered swap and the BSB commander eats a finding in front of the brigade CO.
• —Talking up the 915A Warrant Officer Maintenance Technician path to a gifted specialist without warning him honestly that the selection process is competitive and the schoolhouse has washouts.

The good SSG 91H runs the track shop the BSB commander names in the slide as "maintenance is solid." He turns out two SGT-grade section NCOs per cycle, his CMDP findings are closed before the brigade IG asks, and he has a 915A Warrant Officer packet on the table when the company senior maintenance officer asks if he is interested. The contractor at the ANAD depot already has his number, but the maintenance control officer is fighting brigade to keep him through one more rotation.

You are the platoon sergeant of a maintenance platoon, or the senior 91H/91X in a brigade support battalion. The lieutenant signs; you make sure the slide is true — and the CTC rotation does not go sideways because a Bradley fleet was inadequately prepped.

You run a 30-40 soldier maintenance platoon inside an FSC or the tracked-vehicle section of a BSB maintenance company. Under the Army's senior-NCO MOS consolidation, you are now a 91X advising across the wheeled/tracked/construction/artillery wheeled fleet — not just Bradley and M113 — so you are expected to integrate with the 91A (Abrams) and 91B (wheeled) senior NCOs at the BSB. You write four to five NCOERs per cycle that pick the next SSG and SFC slate. You sit in the brigade maintenance synchronization meeting and walk the line during the brigade CMDP inspection. You build the brigade's tracked warrant officer pipeline into 915A and mentor the shop foremen who will replace you.

• 01Run a maintenance platoon through a brigade CTC rotation — NTC, JRTC, JMRC — sustaining a mixed tracked-and-wheeled fleet across force-on-force.
• 02Defend a brigade-level CMDP inspection for a maintenance platoon with tracked vehicles — months of preparation, zero major findings, defensible minor findings.
• 03Build a brigade warrant officer pipeline into 915A (Automotive Maintenance Warrant Officer) and 915E — at least one technically-strong packet per year going forward.
• 04Translate sustainment-level (formerly DS/GS) tracked-vehicle reach-back through AMC, TACOM, and ANAD (Anniston Army Depot) into language the BSB commander can defend at brigade.
• 05Mentor SSG shop foremen into shop-foreman-of-the-year candidates and SFC-board-ready NCOs across a mixed maintenance platoon.
• 06Operate as the senior maintenance NCO during a real-world deployment maintenance package — contact teams, BDAR, M88A2 HERCULES recovery, TACOM coordination.

• —AR 750-1 — Army Materiel Maintenance Policy; AR 700-138 — Army Logistics Readiness and Sustainability.
• —AR 710-2 / DA PAM 710-2-1 — Supply Policy and Procedures Below the National Level.
• —AR 623-3 + DA PAM 623-3 — NCOER (your evaluations compete against every other PSG's).
• —ATP 4-90 — Brigade Support Battalion; ATP 4-33 — Maintenance Operations.
• —AMC and TACOM published Operational Support Memoranda and Maintenance Information Messages for tracked platforms — the senior-NCO-level guidance traffic between the field and depot.
• —TC 7-22.7 — The Army NCO Guide; ADP 6-22 — Army Leadership.

• —MLC graduate; consider the Maintenance Senior Sergeants Course at Fort Gregg-Adams and the U.S. Army Sergeants Major Academy fellowship if SGM-track.
• —BDAR qualification and credible subject-matter depth across the tracked fleet the platoon maintains — M2/M3, M109, M88A2 at minimum.
• —Brigade-level CMDP inspection passed with no senior-NCO-attributable findings during your tenure.
• —915A / 915E warrant officer accession pipeline producing at least one selected candidate per year.
• —Platoon ACFT pass rate at or above 95%; zero relievable maintenance incidents — no negligent equipment loss, no controlled-exchange violations, no Class VII tracked end items lost.

• —Letting the GCSS-Army deadline-aged tracked-vehicle report run hot without a brief to brigade. The brigade S4 will put the number on the slide anyway; you want to be the one framing it.
• —Confusing tracked-platform expertise with sustainment-maintenance expertise. The SFC who pretends to know what TACOM/ANAD does loses authority with both soldiers and the BSB warrant simultaneously.
• —Skipping the SHARP / EO / command-climate piece because "maintenance is busy." Senior maintenance platoon sergeants lose careers over climate findings as fast as anyone in the battalion.
• —Carrying a personal feud with a peer PSG into the BSB maintenance synchronization meeting. Brigade-level NCOERs notice and the BSB CSM closes the door.
• —Talking up the 915A warrant track to technically gifted soldiers without warning them honestly that selection rates vary by board year and the schoolhouse has real washouts — set them up to compete, not to be surprised.

The good SFC 91H / 91X is the senior maintenance NCO the BSB commander and the BCT CO trust to walk into a CTC rotation and come back with tracked OR rate green, no negligent Class VII loss, and a platoon of SSGs and SGTs ready for the next slate. He runs the brigade's 915A pipeline, his NCOERs pick the next shop-foreman tier, and he is on the short list for First Sergeant of a maintenance company or HHC before he sits MLC.

You are the senior enlisted maintenance voice on a BSB or brigade staff, or the 1SG of a maintenance company. The BCT commander names you in the slide as the reason the brigade's tracked fleet rolls.

As 1SG you run a maintenance company or FSC — 90-130 soldiers, multiple tracked and wheeled shop sections, a complex high-value equipment footprint, the orderly room, the supply room, and the readiness reporting. As MSG you are the brigade's consolidated 91X senior NCO, advising across wheeled, tracked, construction, and artillery wheeled platforms from a brigade-staff seat. As SGM / CSM you set the standard for the enlisted maintenance workforce across a BSB, brigade, or division — training, certifications, retention, the warrant officer pipelines into 915A and 915E. You sit in brigade-and-above sustainment conversations alongside O-5s, AMC Logistics Assistance Representatives (LARs), and TACOM field representatives — and you advise on enlisted talent at echelons above brigade.

• 01Run a maintenance company command climate that produces ASE-certified, ALC/SLC-graduated, BDAR-qualified, deployment-ready 91X NCOs at a rate above the brigade average.
• 02Mentor a warrant officer accession slate (915A / 915E) at the brigade or higher staff level — at least one selected per year, with the technical depth and OER record to compete.
• 03Brief the BCT / Division CG on the brigade's tracked and wheeled maintenance readiness in language the CG can defend at the next echelon — OR trend, Class IX float, mechanic-hours, AMC field-support tempo.
• 04Run a brigade-level maintenance posture during a real-world deployment or major exercise — TACOM coordination, AMC LAR interface, contractor field-service-representative employment on tracked platforms, all of it.
• 05Translate Army sustainment doctrine and TACOM / AMC modernization guidance into enlisted-talent decisions at the unit.
• 06Walk the line during the brigade CMDP inspection and identify the broken systems before the IG OC/T does.

• —AR 600-20 — Army Command Policy; AR 27-10 — Military Justice (you are in the room).
• —AR 750-1 — Army Materiel Maintenance Policy; AR 700-138 — Army Logistics Readiness and Sustainability.
• —AR 710-2 / DA PAM 710-2-1 — Supply Policy and Procedures Below the National Level.
• —AR 638-8 — Army Casualty Program (every senior NCO must know this).
• —AMC, TACOM, and CASCOM (Combined Arms Support Command) published strategic guidance and modernization memoranda.
• —The 1SG Course / USASMA / SGM-A reading list — you are now expected to teach doctrine and translate it down.

• —USASMA / SGM-A completion before competing for command CSM slate.
• —Brigade-level CMDP inspection passed without senior-NCO-attributable findings during your tenure.
• —Company UCMJ rate, retention rate, and SHARP / EO climate index in the top tier of the BSB.
• —Warrant officer accession pipeline producing 1+ selected per year — 915A / 915E is the visible measurable.
• —Zero senior-NCO-level integrity, financial, fraternization, OPSEC incidents. One ends the career permanently.

• —Going public with disagreement with the BSB or BCT commander on a tracked-maintenance risk call. Take the disagreement into the office; walk out aligned.
• —Confusing seniority with technical depth on tracked platforms. The senior NCO who pretends to know what TACOM/ANAD does loses authority with both his soldiers and the BSB warrant; they stop bringing him problems.
• —Letting a 1SG-led maintenance company drift on CMDP because "the warrant will catch it." You and the warrant own it together; the 1SG owns the company climate that makes the warrant's job possible.
• —Treating the 915A warrant slate conversation as transactional. The 915A career is one of the most consequential technical careers in the Army support corps; mentor it like it is.
• —Stopping personal physical training because you are "too senior, too motor-pool." Soldiers stop respecting the diamond when the body stops carrying it.

The good 91H / 91X CSM / 1SG / SGM is the senior NCO the BSB and BCT commanders name without thinking. His maintenance company is the one the BCT loans across the division during rotations because it comes back at higher readiness than it left. His enlisted talent slate is the one HRC quotes in retention briefs. His 915A accession rate is in the upper third of the Army; his rated NCOs are picking up shop-foreman and 1SG chevrons on schedule; and when the brigade rolls out the gate for the worst CTC rotation on the calendar, the BCT commander sleeps because he knows the maintenance NCO walking the track line at 0200 is this one.
