Quartermaster and Chemical Equipment Repairer

You are the new soldier on the repair bench. The laundry system that has to wash 500 sets of uniforms before the battalion rolls does not care that you slept three hours — it cares whether you diagnosed the burner assembly fault and got the unit running.

You completed AIT at Fort Gregg-Adams (renamed from Fort Lee in 2023) under the Quartermaster School and the CBRN School and now you straddle two worlds that nobody else in the company understands. Half your time is QM field-service equipment — Laundry Advanced System (LADS), shower units, textile and canvas repair machines, water purification systems (ROWPU, LWP, TWP). The other half is CBRN detection and decontamination equipment — the M22 ACADA (Automatic Chemical Agent Detection Alarm), M26 JSLSCAD (Joint Service Lightweight Standoff Chemical Agent Detector), M12A1 PDDA (Power-Driven Decontamination Apparatus), and the M26 Decontamination System. You learn TMs by equipment serial number because every system in the shop has its own maintenance history. You pull PMCS, you chase Class IX parts through GCSS-Army, and you hand the senior 91J the right tool before he asks for it twice.

• 01Run operator- and crew-level PMCS on the LADS (Laundry Advanced System) and field shower units per TM 10-3510 series — find the burner fault, the pump fault, or the water-line leak before the system deadlines mid-cycle.
• 02Troubleshoot and repair the M22 ACADA per TM 3-6665-368 — replace the concentrator wheel, the detector cell, and the sampling pump assembly without contaminating the optics bench.
• 03Perform scheduled and unscheduled maintenance on the M12A1 PDDA per TM 3-4230-235 series — pump seals, spray nozzles, engine governor, decon-agent metering, and the DS2/DF-200/RSDL interface.
• 04Open and close GCSS-Army Maintenance Request Orders (MROs) cleanly — fault code, parts requisitioned, labor hours logged, status code updated, customer signature before closing.
• 05Operate and maintain the ROWPU (Reverse Osmosis Water Purification Unit) membrane and pre-filter assembly to TM 5-4610-232 series standard.
• 06Use a multimeter, a manometer, and a flow-rate gauge correctly on QM and CBRN systems — the senior mechanic should not have to recalibrate your readings.

• —TM 10-3510 series — Laundry and bath equipment maintenance (LADS, field shower, laundry sets).
• —TM 3-6665-368 series — M22 ACADA maintenance (detection and alarm system).
• —TM 3-4230-235 series — M12A1 PDDA maintenance (power-driven decontamination apparatus).
• —DA PAM 750-8 — The Army Maintenance Management System (TAMMS) User Manual.
• —AR 750-1 — Army Materiel Maintenance Policy (read it once; refer to it when the senior NCO asks).
• —STP 10-91J14-SM-TG — Soldier's Manual and Trainer's Guide, MOS 91J, skill levels 1-4.

• —GCSS-Army basic user proficiency — receive, diagnose, order parts, close MRO without supervision inside 90 days.
• —ACFT 500+ — the repair bench is not an excuse; your team leader runs PT and you run with him.
• —CBRN mask confidence test and mask fit test current per AR 350-1 and TC 3-11.6 — you work on decon gear, you had better trust your own mask.
• —91J Sustainment Skills Validation passed annually, on the first attempt.
• —Driver's license (OF 346) on the HMMWV and the platform truck that tows the decon trailer — the shop cannot dispatch without a licensed operator.

• —Skipping the leak test on a repaired LADS boiler assembly. The system pressurizes at startup and a missed weld or gasket failure at the field site shuts down laundry ops for the entire battalion.
• —Contaminating the M22 ACADA optics bench by handling the concentrator wheel without gloves. The false-alarm rate spikes and the company CBRN NCO loses trust in the detector you just touched.
• —Closing an MRO in GCSS-Army without the road test or operational test complete. The next user finds the system still broken and your name is in the maintenance log.
• —Using the wrong decon agent concentration in the M12A1 PDDA metering system. Under-concentration fails the decon standard; over-concentration damages the equipment surfaces and wastes Class V(W) supply.
• —Leaving tools inside an equipment housing after repair. A forgotten wrench inside a pump assembly damages the impeller on startup and the incident report traces back to your signature block.

The good cherry 91J is the soldier the shop chief sends to the deadline LADS at 1600 on a Friday because it will come back operational and signed off for Monday's dispatch. By month nine he is closing MROs in GCSS-Army without supervision and can swap between QM and CBRN equipment without needing the TM open to every page. By month eighteen he has the M22 ACADA troubleshooting tree memorized and the senior 91J is using him to train the next cherry. The CBRN NCO at the supported company trusts his decon gear because it works every time.

You are the diagnostic brain on the bench. The field shower that has stumped two privates and the CBRN system that keeps throwing false alarms — both land on your workstation because the shop chief trusts your troubleshooting.

You run a 2-3 soldier work team across the QM/CBRN equipment mix. You diagnose rather than swap parts. You walk a private through a burner ignition sequence on the LADS and you walk a CBRN NCO through why his M22 ACADA is alarming on humidity rather than agent. You sign for Test, Measurement, and Diagnostic Equipment (TMDE) — calibrated gauges, flow meters, electrical test sets — and you treat them like the expensive, perishable assets they are. You manage the sub-section's MRO queue in GCSS-Army and you are the soldier who actually knows whether the Class IX parts are on the shelf or still chasing through TACOM's system.

• 01Diagnose a burner-assembly, pump-assembly, or water-system fault across the QM field-service fleet without throwing parts at it — fuel pressure, ignition sequence, water flow rate, and electrical continuity before the parts requisition.
• 02Troubleshoot the M26 JSLSCAD standoff detection system per TM 3-6665-series — optics alignment, laser module, processor faults, and the software-diagnostic interface.
• 03Perform intermediate-level repair on the M12A1 PDDA — engine rebuild, pump overhaul, spray-nozzle replacement, decon-agent plumbing, and operational testing per TM 3-4230-235 series.
• 04Operate the sub-section's TMDE per AR 750-43 — multimeter calibration cycles, manometer cert, flow-gauge cert tracked through the TMDE Support Center.
• 05Lead a decontamination system operational test under the CBRN NCO's supervision — set up, throughput, agent concentration verification, equipment washdown, and teardown in the doctrinal time standard.
• 06Train new 91Js on PMCS procedures — not by lecture, by walking through the equipment and pointing at what they missed.

• —AR 750-1 — Army Materiel Maintenance Policy (own this, do not just read it).
• —AR 750-43 — Test, Measurement, and Diagnostic Equipment (TMDE) — the calibration backbone of every reading you trust.
• —DA PAM 750-1 — Commanders' Maintenance Handbook.
• —TM 3-4230 series — Decontamination equipment maintenance (M12A1 PDDA, M26 Decontamination System).
• —TM 3-6665 series — CBRN detection equipment maintenance (M22 ACADA, M26 JSLSCAD).
• —ATP 4-90 — Brigade Support Battalion (your formation's doctrinal home if you are in an FSC or BSB).

• —BLC graduate; promotion-points stacked with weapons quals, schools, CBRN certifications, and college credits through Army Tuition Assistance.
• —Sub-section MRO closure rate at or above 90% within the published window; first-time-fix rate measurable and trending up.
• —Zero TMDE calibration lapses on the gear you sign for. One out-of-cal flow gauge in a sustainment inspection calls every reading you took into question.
• —ACFT 540+ minimum — the repair bench is not a fitness waiver.
• —CBRN defense proficiency at Warrior Skills Level 2 — you repair the detection gear, you must know how it integrates into the company's CBRN defense plan.

• —Throwing parts at a diagnosis on the M22 ACADA. The Class IX cost on detection-system components is high and the brigade S4 asks why a SPC is ordering concentrator wheels monthly.
• —Skipping the operational test after repairing the M12A1 PDDA pump system. The decon site goes live, the system fails at throughput, and the supported unit's decon timeline slips.
• —Closing MROs in GCSS-Army before the operational test confirms the repair. The equipment comes back broken and your name is in the log.
• —Letting TMDE cycle out of calibration. Every measurement you took with that manometer is now suspect, which means every pressure reading you signed off in the last 90 days is suspect.
• —Mixing QM and CBRN tools in the same kit without decontamination verification. Cross-contamination from decon-agent residue to a QM water-purification system creates a health hazard the battalion surgeon traces back to your bench.

The good SPC 91J is the repairer the shop chief sends to the equipment that has eaten two cherries and a frustrated CBRN NCO, because it will come back diagnosed, repaired, operationally tested, and closed in GCSS-Army before the BUB. He can swap between the LADS burner bench and the M22 ACADA optics bench without losing a step. The bay chief is fighting to keep him on the BLC slate so he can run a sub-section as a sergeant inside a year.

You are an NCO now and you run a section. The maintenance control sergeant is mentoring you, the company commander is leaning on you for equipment readiness, and the dispatch book on both the QM and CBRN fleets is yours to defend.

You run a 3-5 soldier section inside an FSC, a BSB maintenance company, a CBRN battalion, or a chemical company. You write counseling statements on the 14th, you build the section's training calendar around the dual equipment portfolio, and you brief the maintenance status of both the QM field-service fleet and the CBRN detection/decon fleet at the company production meeting. You sign for hundreds of thousands of dollars of TMDE, Class VII end items, and shop-stock. In garrison you run the shop, write NCOERs on your soldiers, and push them through BLC packets and CBRN school slots. In the field you are at the FSC logistics release point or the CBRN company support area, keeping the decon line and the field laundry running under operational conditions.

• 01Build and defend a section maintenance production schedule — green/amber/red across both QM and CBRN fleets, with realistic mechanic-hours and Class IX float.
• 02Run a section through a field decontamination operation — M12A1 PDDA setup, throughput management, agent concentration monitoring, personnel decon line, equipment washdown, and teardown within the doctrinal timeline.
• 03Conduct quarterly Command Maintenance Discipline Program (CMDP) inspections at the section level — TMDE calibration, MRO paperwork, CBRN-specific safety, accountability, all defensible.
• 04Sign and defend a sub-hand receipt for TMDE, CBRN detection systems, QM field-service equipment, and Class VII end items — quarterly inventories on time, shortage annexes clean.
• 05Operate GCSS-Army at the section NCO level — open / monitor / close MROs, run the section's readiness reports, defend the Class IX demand history.
• 06Mentor your juniors on diagnosis over parts-replacement. If they leave your section as parts-changers instead of troubleshooters, that is on you.

• —AR 750-1 — Army Materiel Maintenance Policy; AR 710-2 — Supply Policy Below the National Level.

• —Section operational readiness (OR) rate at or above the company average across both QM and CBRN equipment sets.
• —CMDP inspection finding rate trending down quarter-over-quarter.
• —NCOERs written in measurable, defensible bullets — MRO closure rate, OR rate, decon throughput, 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 paper.
• —Signing the dispatch on a CBRN system your private closed in GCSS-Army without your section road test or operational test. The system fails at the decon site and your name is on the dispatch.
• —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 SPC act as the diagnostic lead on the M26 JSLSCAD when he is not trained on the system's optical alignment. The misdiagnosis writes off a laser module 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 Class IX float.

The good SGT 91J runs a section whose OR rate the FSC commander names in the slide without surprise — across both the QM and CBRN fleets. His juniors close MROs cleanly, his ALC graduates show up on the SSG board with measurable bullets, and the CBRN NCO at the supported company trusts every piece of detection and decon gear that came through his section. The shop chief is fighting to keep him on the SLC slate because a section that runs both equipment families at this level is rare.

The shop is yours. The maintenance control officer signs; you run the production floor across every QM and CBRN system the company owns.

You are the shop foreman of a QM/CBRN maintenance section inside a BSB, a chemical company, or a CBRN battalion support element. You manage 10-20 soldiers across the dual equipment portfolio — field laundry, bath/shower, textile repair, water purification, CBRN detection suites, and decontamination systems. You build the company's quarterly maintenance training brief input. You run the GCSS-Army production board for the company — open work orders, parts on order, scheduled services, deadline reports, and the brigade-level readiness rollup. You sit on the brigade's monthly maintenance synchronization meeting and you are the senior 91J voice when the BSB commander asks why a supported unit's CBRN detection readiness is red.

• 01Run a GCSS-Army production board at the company level — load-leveling mechanics across QM and CBRN systems, parts triage, scheduled services vs. surge, with a defensible 30/60/90 outlook.
• 02Build a Quarterly Training Brief (QTB) input that aligns mechanics with CBRN sustainment training, QM equipment certification, and the brigade's deployment cycle.
• 03Defend a Command Maintenance Discipline Program (CMDP) inspection at the company level — TMDE calibration, CBRN safety, training records, shop safety, all clean.
• 04Lead a brigade-level CBRN decontamination exercise — M12A1 PDDA and M26 system employment, throughput assessment, agent logistics, and coordination with the CBRN officer.
• 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, CBRN readiness posture, mechanic-hours available vs. 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).
• —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.
• —FM 3-11 — CBRN Operations (brigade and above context for your shop's mission).

• —SLC graduate; MLC packet built; consider the Quartermaster Senior Leaders Course at Fort Gregg-Adams as a differentiator.
• —Company-level OR rate at or above the brigade average over rolling quarters across both QM and CBRN equipment.
• —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 delta in soldiers selected.
• —Zero CBRN safety incidents traceable to maintenance error — decon-agent exposure, detection-system failure in a live-agent environment, or contaminated water-purification output.

• —Inflating the GCSS-Army OR rate by sliding deadline CBRN detection faults into scheduled-service 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.
• —Authorizing a controlled exchange of CBRN detection components without the paperwork because the exercise timeline is tight. The CSM finds the un-papered swap and the BSB commander eats a finding.
• —Treating the CBRN fleet as secondary to the QM fleet. The detection and decon systems are low-density, high-criticality — a single unserviceable M22 ACADA at the wrong time is a force protection gap that the brigade commander briefs at division.
• —Pushing the 914A (Allied Trades Warrant Officer) packet conversation past a soldier who is technically gifted. The 914A path is one of the most consequential technical careers in the QM/CBRN maintenance space; mentor it like it is.

The good SSG 91J runs the shop the BSB commander names in the slide as "QM and CBRN 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 914A Warrant Officer packet on the table when the company senior maintenance officer asks if he is interested. The CBRN officer at the supported battalion trusts every detector and decon system that passed through this shop because the OR rate is visible and the operational test records are clean.

You are the platoon sergeant of a QM/CBRN maintenance platoon, or the senior 91J in a brigade support battalion. The lieutenant signs; you make sure the slide is true.

You run a 20-30 soldier maintenance platoon inside an FSC, a BSB maintenance company, or the QM/CBRN maintenance section of a chemical battalion. At the senior-NCO level the Army merges the QM and CBRN maintenance specialties under the broader sustainment-maintenance umbrella, so you advise across the full QM field-service and CBRN detection/decontamination portfolio. You write four to five NCOERs per cycle that pick the next SSG / SFC slate. You sit on the brigade maintenance synchronization meeting and you walk the line during the brigade CMDP inspection. You build the brigade's warrant officer pipeline into 914A.

• 01Run a maintenance platoon through a brigade CTC rotation — JRTC, NTC, JMRC — sustaining the QM field-service and CBRN detection/decon fleet across the force-on-force.
• 02Defend a brigade-level Command Maintenance Discipline Program inspection — months of preparation, zero major findings, defensible minor findings.
• 03Build a brigade warrant officer pipeline into 914A (Allied Trades Warrant Officer) with at least one packet per year going forward.
• 04Translate sustainment-maintenance reach-back through TACOM and the Joint Program Executive Office for CBRN Defense (JPEO-CBRND) into language the BSB commander can defend at brigade.
• 05Mentor SSG shop foremen into SFC-board-ready NCOs.
• 06Operate as the senior QM/CBRN maintenance NCO during a real-world deployment or CBRN exercise — decon operations, detection system sustainment, field-service equipment support, all of it.

• —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 go up against every other PSG's).
• —FM 3-11 — CBRN Operations; ATP 3-11.32 — CBRN Passive Defense; ATP 3-11.36 — CBRN Decontamination.
• —ATP 4-90 — Brigade Support Battalion; ATP 4-33 — Maintenance Operations.
• —TC 7-22.7 — The Army NCO Guide; ADP 6-22 — Army Leadership.

• —MLC graduate; consider the Quartermaster Senior Leaders Course at Fort Gregg-Adams and the USASMA fellowship if SGM-track.
• —Brigade-level CMDP inspection passed with no senior-NCO-attributable findings during your tenure.
• —914A warrant officer accession pipeline producing at least one selected candidate per year.
• —Platoon ACFT pass rate at or above 95%; platoon-level zero CBRN safety incidents (no decon-agent exposure events, no detection-system failures during live-agent ops, no contaminated water output).
• —Platoon retention rate at or above the BSB average — soldiers leave 91J at senior-NCO level because the civilian market values the dual-skill set.

• —Letting the GCSS-Army deadline-aged report run hot on CBRN detection systems without explaining it to brigade. The brigade S4 will brief the number anyway; you want to be the one framing the risk.
• —Confusing QM field-service maintenance expertise with CBRN sustainment-level expertise. The senior NCO who pretends to know what JPEO-CBRND is fielding loses authority with both his soldiers and the BSB warrant.
• —Skipping the SHARP / EO / climate piece because "maintenance is busy." Senior maintenance NCOs lose careers over command-climate findings as fast as anyone.
• —Carrying a personal feud with a peer PSG into the BSB. Brigade-level NCOERs notice and the BSB CSM closes the door.
• —Talking the 914A warrant track up to soldiers without warning them honestly that the selection rate varies by board and the school pipeline can be lengthy.

The good SFC 91J is the senior QM/CBRN maintenance NCO the BSB commander and the BCT CO trust to walk into a CTC rotation and come back with OR rate green on both fleets, no CBRN safety incidents, and a platoon of SSGs and SGTs ready to take the next slot. He runs the brigade's 914A pipeline, his NCOERs pick the next shop-foreman slate, and he is on the short list for First Sergeant of a maintenance company before he sits MLC.

You are the senior enlisted QM/CBRN maintenance voice on a BSB or brigade staff, or the 1SG of a maintenance company. The BSB / BCT commander names you in the slide as the reason both the field-service fleet and the CBRN detection/decon fleet stay green.

As 1SG you run a maintenance company or FSC — 80-130 soldiers, multiple shop sections spanning the full QM and CBRN equipment portfolio, the orderly room, the supply room, and the readiness reporting chain. As MSG you are the brigade maintenance senior NCO for QM/CBRN systems, advising across the field-service, detection, and decontamination fleets. As SGM / CSM you set the standard for the enlisted QM/CBRN maintenance workforce across a BSB, brigade, or division — training, certifications, retention, warrant officer pipelines into 914A. You sit in the brigade-and-above sustainment conversation alongside O-5s, AMC LARs, and JPEO-CBRND representatives, and you advise on enlisted talent slate at echelons above brigade.

• 01Run a maintenance company / brigade maintenance cell command climate that produces certified, ALC/SLC-graduated, deployment-ready 91J NCOs at a rate above the brigade average.
• 02Mentor a warrant officer accession slate (914A) at the brigade or higher staff level — at least one selected per year, with the technical record to compete.
• 03Brief the BCT / Division CG on the brigade's QM field-service and CBRN maintenance readiness in language the CG can defend at the next higher echelon — OR trend, Class IX float, CBRN detection readiness posture, mechanic-hours, AMC field-support tempo.
• 04Run a brigade-level maintenance posture during a real-world deployment or major CBRN exercise — TACOM coordination, JPEO-CBRND interface, contractor field-service representative employment, all of it.
• 05Translate the Army's sustainment doctrine and the CBRN modernization guidance into enlisted-talent decisions at the unit.
• 06Walk the line during the brigade CMDP inspection and identify the broken systems — QM and CBRN — 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.
• —FM 3-11 — CBRN Operations; ATP 3-11.32 — CBRN Passive Defense; ATP 3-11.36 — CBRN Decontamination.
• —AMC, TACOM, and CASCOM 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 pass 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 from your unit — 914A is the visible measurable.
• —Zero senior-NCO-level integrity, financial, fraternization, OPSEC, or CBRN safety incidents. One ends the career permanently.

• —Going public with disagreement with the BSB or BCT commander on a CBRN maintenance-risk call. Take the disagreement in the office; walk out aligned.
• —Confusing seniority with technical depth. The Army keeps senior QM/CBRN maintenance NCOs who hire, promote, and mentor mechanics sharper than they are. Soldiers see the senior NCO who pretends to know GCSS-Army and 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 914A warrant slate conversation as transactional. The 914A career is one of the most consequential technical careers in the QM/CBRN maintenance space; mentor it like it is.
• —Stopping personal physical training because you are too senior and too maintenance-focused. Soldiers stop respecting the diamond when the body stops carrying it.

The good QM/CBRN maintenance 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 914A 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 a CBRN-intensive rotation, the BCT commander sleeps because he knows the senior maintenance NCO walking the decon line at 0200 is this one.
