Computer/Detection Systems Repairer

You are the new bench tech on the detection line. The perimeter alarm that went dead at 0200 does not care that you are still learning the TM — it cares whether you can isolate the fault and get the sensor back online before the patrol returns.

You completed AIT at Fort Gregg-Adams, VA (renamed from Fort Lee in 2023) under the Ordnance School and now you sit in a CBRN reconnaissance company, a military police company, a force protection cell, or the brigade's electronic maintenance shop. Your world is detection and alarm systems — chemical agent detectors (the JCAD / M4A1 JCAD, the ACADA system), radiation detection equipment (the AN/PDR-77, AN/VDR-2 RADIAC sets), intrusion detection systems (TASS, REMBASS, the various perimeter security sensor suites), and the automated data processing equipment that ties them together. You pull PMCS on detection gear the same way a 91B pulls PMCS on a HMMWV — by the TM, every item, every time. You run calibration checks, swap line-replaceable units, solder to IPC standard when authorized, and close work orders in GCSS-Army before the end of the day.

• 01Run a complete PMCS and operational check on the JCAD (Joint Chemical Agent Detector) and ACADA (Automatic Chemical Agent Detector Alarm) per the applicable TM — verify detection sensitivity, battery condition, and alarm function before the equipment goes to the field.
• 02Operate a multimeter, oscilloscope, and the unit's AN/USM-series test equipment to fault-isolate detection and alarm system failures at the LRU (line-replaceable unit) level.
• 03Perform board-level and LRU-level repairs on intrusion detection sensors — TASS (Tactical Automated Security System) and REMBASS (Remotely Monitored Battlefield Sensor System) components — per the applicable TM 11-series procedures.
• 04Calibrate and verify radiation detection instruments (AN/PDR-77, AN/VDR-2 RADIAC sets) against known sources per the TM and the unit's radiation safety SOP.
• 05Solder to IPC J-STD-001 standards — through-hole and surface-mount — on the boards and harnesses you are authorized to repair at field level.
• 06Close a maintenance work order in GCSS-Army with the correct fault code, parts consumed, labor hours, and the user's signature before the equipment leaves the shop.

• —TM 3-6665-series — Chemical agent detection equipment technical manuals (JCAD, ACADA, M256 kit series).
• —TM 11-series — Electronics maintenance technical manuals for detection, alarm, and sensor systems.
• —AR 750-1 — Army Materiel Maintenance Policy (the parent regulation for every repair you perform).
• —DA PAM 750-8 — The Army Maintenance Management System (TAMMS) User Manual.
• —STP 9-94F1-SM-TG — Soldier's Manual and Trainer's Guide, MOS 94F, Skill Level 1 (your task-conditions-standards baseline).
• —TB 43-0116 — Identification of Radioactive Items in the Army Supply System (radiation safety for RADIAC maintenance).

• —IPC J-STD-001 soldering certification — the bench-level gate that determines who touches a populated board in the shop.
• —ESD (electrostatic discharge) workstation discipline maintained daily — wrist strap, mat continuity check, humidity control — or you fry the next $25K detection board.
• —Closed work orders on first turn-in at or above the section average — re-opens mean the supported unit lost detection coverage twice.
• —ACFT 500+ — the maintenance section does not get to be the soft-MOS shop; your team leader runs PT and you run with him.
• —94F Sustainment Skills Validation passed annually, first attempt.

• —Skipping the calibration verification on a RADIAC set before returning it to the user. The unit deploys with an instrument that reads low, and the CBRN officer makes decisions off data your shop certified. That is a safety-of-force failure.
• —Powering up a detection system on the bench without following the TM warm-up and self-test sequence. You get a false-positive alarm response, call it good, and the system fails to detect in the field.
• —Closing a work order in GCSS-Army with "repaired" when you swapped an LRU without isolating the root cause. The equipment comes back in 10 days with the same fault and the section sergeant remembers your name.
• —Handling radioactive check sources outside the unit's radiation safety SOP. One deviation and the Radiation Safety Officer (RSO) is in the shop with the company commander.
• —Writing a one-word fault narrative ("broken") in GCSS-Army. Tobyhanna Army Depot or the sustainment-level shop sends it back uncoded because they cannot reproduce your ticket.

The good 94F cherry is the soldier the section sergeant sends to the CBRN company's downed ACADA at 1500 on Friday because she knows the detector comes back calibrated, work-order-closed, and staged for the field problem on Monday. By month nine she is signing for her own tool roll and calibration sources; by month eighteen she has IPC soldering on the wall and the senior repairer is talking to her about the 948B warrant track.

You are the technical floor of the section. The new privates learn fault isolation by watching you trace a signal path, and the supported unit calls you by name when the perimeter sensor suite goes dark.

You run the bench independently — intake to closed work order, fault verification through component-level repair to functional validation, on every detection and alarm system the section is authorized to maintain at field level. You specialize across the detection portfolio: chemical agent detection (JCAD, ACADA, the M4-series detectors), radiation detection (AN/PDR-77, AN/VDR-2 RADIAC sets, the various dosimetry readers), intrusion detection and perimeter security sensor systems (TASS, REMBASS, RAID — Remote Alarm and Intelligent Detection), and the automated data processing equipment that aggregates sensor feeds. You are the soldier the platoon sergeant pushes forward to a battalion TOC during a field problem when the force protection sensor net goes down. You start training the new privates on bench SOP — fault narrative, parts pulls, ESD discipline, calibration procedure.

• 01Fault-isolate to the component level on TASS and REMBASS sensor suites — control units, sensor strings, relay nodes, communications links — using the TM 11-series fault-isolation procedures and the section's test equipment.
• 02Maintain and calibrate chemical agent detection systems (JCAD, ACADA) to manufacturer and TM standards, including sensitivity verification against simulant sources.
• 03Perform field-level maintenance on automated data processing equipment — tactical computer systems, display units, and the interface hardware that ties detection sensors to the common operating picture.
• 04Operate AN/USM-series and AN/PRM-series test sets without freelancing — calibration-current, reference-traceable, signed out daily from the TMDE cage.
• 05Train a new PFC on the bench SOP in two weeks — fault narrative, ESD discipline, calibration verification, GCSS-Army documentation — without leaving him able to embarrass the section.
• 06Run a forward maintenance element during a field problem or CTC rotation — tool roll, test equipment, LRU float, and the TMs for every system the supported unit carries.

• —AR 750-1 — Army Materiel Maintenance Policy; DA PAM 750-8 — TAMMS.
• —TM 11-series — Electronics maintenance technical manuals for detection, alarm, intrusion detection, and ADP equipment.
• —TM 3-6665-series — Chemical agent detection equipment (JCAD, ACADA, M256 series).
• —AR 750-43 — Army Test, Measurement, and Diagnostic Equipment (TMDE) — the calibration backbone for every reading you trust.
• —ATP 4-33 — Maintenance Operations (your doctrinal home for how the section fits into the BSB / FSC maintenance structure).
• —FM 3-11 — Chemical, Biological, Radiological, and Nuclear Operations (understand the mission your equipment supports).

• —IPC J-STD-001 + IPC-A-610 (Acceptability of Electronic Assemblies) certifications maintained current.
• —Field-level certification on every detection platform the section maintains — signed off by the section sergeant, current in the certification binder.
• —BLC graduate; promotion-points stack built with weapons quals, civilian certifications through Army Credentialing Assistance (CompTIA A+, Security+, electronics technician credentials), and college credit.
• —Work order re-open rate at or below the section average — the metric the BDE maintenance officer reads in the slide.
• —ACFT 540+ — the promotion board reads fitness before they read bench skill.

• —Cannibalizing parts from a lower-priority detection system to fix the priority job without a controlled-substitution memo. The supply audit catches it and both work orders are corrupted.
• —Returning a RADIAC set to the user without running the full calibration verification against a known source. The unit deploys to a contaminated area and the detector reads clean. That scenario ends careers.
• —Closing a TASS work order without re-integrating the sensor into the full system and verifying alarm transmission to the monitoring station. The supported unit discovers the gap at 0200 during a live force protection mission.
• —Signing for the section tool roll, the bench test equipment, and $80K in calibrated instruments on one open hand-receipt because "we trust each other." The IG inventory writes you all up.
• —Posting a photo of the workbench to social media. The serial numbers on the detection equipment and the intrusion sensor components in the background are exploitable — OPSEC scrapes social media for exactly this.

The good Specialist 94F is the tech the brigade force protection officer calls when the perimeter sensor net drops during a JRTC rotation, because she will fault-isolate the system in the rain, swap the bad relay node, verify end-to-end alarm function, and close the work order before the BDE TOC has to brief the gap. She has IPC on the wall, CompTIA A+ done through Army CA, and the 948B/948E warrant conversation is already on the table.

You are an NCO now and the technical lead of a detection systems repair section. The maintenance control officer briefs the commander off your production data and the supported units measure readiness by whether your section returned their sensors on time.

You own a 3-5 soldier detection systems repair section inside the BCT FSC, the BSB maintenance company, or the CBRN battalion's maintenance element. You write counseling statements on the 14th, you build the section training plan around IPC recertification, platform qualification, and calibration discipline. You brief the maintenance control officer on bench throughput, TMDE calibration status, and the LRU backorder situation. You stand up the forward maintenance team for field problems and CTC rotations. You sign for hundreds of thousands of dollars of test equipment, calibration sources, and detection systems, and you are the company commander's named point of contact when a detection system is "deadlined" in the readiness slide.

• 01Build and defend a section production schedule — green/amber/red across the detection systems work-order queue, with realistic bench-hours and LRU float.
• 02Run a section through a field-maintenance deployment at NTC / JRTC — forward maintenance elements, CBRN detection equipment support, force protection sensor sustainment, all of it.
• 03Conduct Command Maintenance Discipline Program (CMDP) inspections at the section level — paperwork, TMDE calibration records, ESD compliance, shop safety, all defensible.
• 04Sign and defend a sub-hand receipt for test equipment, calibration sources, and Class VII detection systems — quarterly inventories on time, shortage annexes clean.
• 05Operate GCSS-Army at the section NCO level — open/monitor/close work orders, run section readiness reports, defend the Class IX demand history to the maintenance control officer.
• 06Mentor your bench techs on systematic fault isolation — if they leave your section as parts-swappers instead of diagnosticians, that is on you.

• —AR 750-1 — Army Materiel Maintenance Policy; AR 710-2 — Supply Policy Below the National Level.
• —AR 750-43 — Army Test, Measurement, and Diagnostic Equipment (TMDE) — you own the calibration program for every instrument in the section.
• —AR 623-3 — NCOER (you write them now); AR 600-8-19 — Enlisted Promotions.
• —ATP 4-33 — Maintenance Operations; ATP 4-90 — Brigade Support Battalion.
• —DA PAM 750-1 — Commander's Maintenance Handbook.
• —TC 7-22.7 — The Army NCO Guide; ADP 6-22 — Army Leadership.

• —ALC graduate within the window — SLC packet on the bench when E-6 enters the conversation.
• —IPC J-STD-001 Certified IPC Trainer (CIT) status — the section NCO who can certify his own soldiers on soldering is the section NCO the company commander does not have to send to a school.
• —Section work-order re-open rate at or below the company average; TMDE calibration currency at 100% — one lapsed instrument and every reading taken with it is suspect.
• —NCOERs written in measurable bullets — work-order throughput, calibration compliance, soldiers certified and school-slotted.
• —ACFT 540+ at this rank; section fitness on the company-level slide.

• —Signing a dispatch on a detection system your private closed in GCSS-Army without your own functional verification. The system fails in the field and your name is on the work order.
• —Hiding a CMDP shortcoming from the maintenance control officer to "fix it before the inspection." The IG finds it and the company eats a finding attributed to your section.
• —Letting a SPC act as the lead on a system he is not platform-certified on because "he is sharp." The misdiagnosis damages a detection board and the replacement is a six-figure depot item.
• —Skipping the TMDE calibration status review before the company production meeting. The maintenance control officer shows up to the BDE sync without the data.
• —Writing counselings verbally instead of on paper. The relief-for-cause is on you when the company commander asks why a soldier was relieved without documentation.

The good SGT 94F runs a section whose work-order throughput the maintenance control officer names in the slide without surprise. His bench techs close work orders cleanly, his TMDE calibration binder is inspection-ready on any given Tuesday, and the supported CBRN company trusts the section to field-verify their detection gear before a deployment. The contractor at the gate already has his number, but the maintenance control officer is fighting to keep him on the SLC slate because a section like this is rare.

The electronics shop is yours. The maintenance control officer signs; you run the production floor and own the calibration program that backs every reading the section takes.

You are the shop foreman of the detection and electronic systems maintenance section in a BSB maintenance company, or the senior 94F in a brigade-level support element. You manage 8-15 bench techs across multiple detection platform families — chemical, radiological, intrusion detection, and ADP. You build the company's quarterly maintenance training brief input for the detection portfolio. You run the GCSS-Army production board for the section — open work orders, parts on order, TMDE calibration schedules, and the brigade-level readiness rollup for detection equipment. You sit on the brigade's monthly maintenance synchronization meeting and you are the senior detection-systems voice when the BSB commander asks why a CBRN company's equipment readiness is red.

• 01Run a GCSS-Army production board at the shop level — load-leveling bench techs across detection platform families, parts triage, TMDE calibration scheduling, with a defensible 30/60/90 outlook.
• 02Build a Quarterly Training Brief (QTB) input that aligns bench techs with platform qualification, IPC recertification, and the brigade's deployment cycle.
• 03Defend a CMDP inspection at the company level for the detection systems portfolio — TMDE records, ESD compliance, calibration source accountability, shop safety, all clean.
• 04Lead a brigade-level detection equipment sustainment package during a CTC rotation or deployment — forward maintenance teams, LRU float management, reach-back to Tobyhanna Army Depot.
• 05Mentor section sergeants into shop-foreman-ready candidates without losing your own SLC bench position.
• 06Translate detection equipment readiness risk into language the FSC / BSB commander can defend at brigade — OR trend, LRU backorder aging, TMDE calibration currency.

• —AR 750-1 — Army Materiel Maintenance Policy; AR 710-2 — Supply Policy.
• —AR 750-43 — Army TMDE (you own the calibration program now, not just the instruments).
• —AR 700-138 — Army Logistics Readiness and Sustainability.
• —AR 623-3 + DA PAM 623-3 — NCOER (you write SGT-level evaluations).
• —ATP 4-33 — Maintenance Operations; ATP 4-90 — Brigade Support Battalion.
• —FM 3-11 — CBRN Operations (understand the operational context your equipment supports at the brigade level).

• —SLC graduate; MLC packet built; consider the Maintenance Senior Sergeants Course at Fort Gregg-Adams as a differentiator.
• —IPC J-STD-001 Certified IPC Trainer (CIT) — the SSG who can run the certification internally saves the unit thousands in school-seat costs.
• —Shop-level detection equipment OR rate at or above the brigade average over rolling quarters; TMDE calibration delinquency at zero.
• —CMDP inspection findings at the company level closed before the next quarterly review.
• —NCOER profile defensible at brigade — measurable bullets on work-order throughput, calibration compliance, soldier development.

• —Inflating the detection equipment OR rate by sliding deadline faults into "awaiting parts" when the parts have been on the shelf for a week. The brigade S4 sees the demand history and the maintenance control officer eats it with you in the room.
• —Skipping the TMDE calibration program review before the brigade sync. One lapsed test set means every reading your section took with it is now suspect — and every system "verified" with that instrument needs re-verification.
• —Authorizing a controlled exchange of a detection LRU without the paperwork. The CSM finds the un-papered swap and the BSB commander eats a finding in front of the brigade CO.
• —Confusing field-level repair authority with sustainment-level work. The detection boards that belong at Tobyhanna stay at Tobyhanna — the SSG who freelances depot-level repair and damages a board owns the six-figure replacement.
• —Pushing the 948B / 948E warrant officer conversation past a soldier who is technically gifted. The warrant path is one of the most consequential technical careers in the Army maintenance corps — mentor it like it is.

The good SSG 94F runs the shop the BSB commander names in the slide as "detection maintenance is solid." He turns out two SGT-grade section NCOs per cycle, his TMDE calibration binder survives the IG unannounced, and he has a 948B or 948E Warrant Officer packet on the table when the company senior maintenance officer asks. The contractor at Tobyhanna is already calling, 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 94-series NCO in a brigade support element. The lieutenant signs; you make sure the calibration program, the production board, and the talent pipeline are all true.

You run a 20-30 soldier maintenance platoon inside an FSC or the electronics section of a BSB maintenance company. At this rank you have likely been consolidated under the 94-series senior NCO umbrella — advising across the electronics repair, detection systems, and related maintenance portfolios, not just one platform family. You write four to five NCOERs per cycle that pick the next SSG / SFC slate. You sit on the brigade maintenance synchronization meeting and walk the line during the brigade CMDP inspection. You build the brigade's warrant officer pipeline into 948B (Electronic Systems Maintenance Warrant Officer) and 948E (Senior Electronic Systems Maintenance Warrant Officer). You interface with Tobyhanna Army Depot and the CECOM (Communications-Electronics Command) field support elements on sustainment-level issues that exceed the field.

• 01Run a maintenance platoon through a brigade CTC rotation — NTC, JRTC, JMRC — sustaining detection, electronic, and sensor systems across the brigade's force protection and CBRN reconnaissance posture.
• 02Defend a brigade-level CMDP inspection — months of preparation, zero major findings, calibration program defensible across every instrument in the platoon.
• 03Build a brigade warrant officer pipeline into 948B / 948E — at least one packet per year going forward.
• 04Translate sustainment-level reach-back through CECOM and Tobyhanna Army Depot into language the BSB commander can defend at brigade — what Tobyhanna owns, what the field owns, where the seam is.
• 05Mentor SSG shop foremen into senior-NCO-ready candidates and SFC-board-ready technicians.
• 06Operate as the senior detection/electronics maintenance NCO during a deployment maintenance package — forward repair, calibration support, LRU management, depot reach-back.

• —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).
• —ATP 4-33 — Maintenance Operations; ATP 4-90 — Brigade Support Battalion.
• —CECOM and Tobyhanna Army Depot published support memoranda — 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 if SGM-track.
• —IPC Master Instructor / Certified IPC Trainer status — the SFC who runs the brigade's internal IPC program is the SFC who saves the brigade $50K a year in school seats.
• —Brigade-level CMDP inspection passed with no senior-NCO-attributable findings during your tenure.
• —948B / 948E 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 calibration lapses leading to safety incidents, no controlled-exchange violations.

• —Letting the GCSS-Army deadline-aged report run hot without explaining it to brigade. The brigade S4 will brief the number anyway; you want to be the one framing it.
• —Confusing platform expertise with sustainment-level authority. The senior NCO who pretends to know what Tobyhanna does loses credibility 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 948B warrant track up to soldiers without warning them honestly that the selection rate varies and the school washes some out. Set expectations, then mentor the packet.

The good SFC 94F is the senior electronics/detection maintenance NCO the BSB commander and the BCT CO trust to walk into a CTC rotation and come back with detection equipment OR rate green, no negligent equipment loss, and a platoon of SSGs and SGTs ready to take the next slot. He runs the brigade's 948B/948E pipeline, his NCOERs pick the next shop-foreman slate, and he is on the short list for First Sergeant of a maintenance company or HHC.

You are the senior enlisted electronics/detection 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 the brigade's detection and sensor posture holds.

As 1SG you run a maintenance company — 80-130 soldiers, multiple shop sections including electronics, detection, and sensor repair, a complex TMDE footprint, the orderly room, the supply room, and the readiness reporting. As MSG you are the brigade maintenance senior NCO for the electronics and detection portfolio, the consolidated 94-series advisor across the detection, alarm, and electronic systems maintenance workforce. As SGM / CSM you set the standard for the enlisted electronics maintenance workforce across a BSB, brigade, or division — training, certifications, retention, warrant officer pipelines into 948B and 948E. You sit in the brigade-and-above sustainment conversation alongside O-5s and CECOM / Tobyhanna field support elements, and you advise on enlisted talent slate at echelons above brigade.

• 01Run a maintenance company / brigade electronics maintenance cell command climate that produces IPC-certified, ALC/SLC-graduated, deployment-ready 94-series NCOs at a rate above the brigade average.
• 02Mentor a warrant officer accession slate (948B / 948E) at the brigade or higher staff level — at least one selected per year.
• 03Brief the BCT / Division CG on the brigade's detection and electronic systems readiness in language the CG can defend at the next higher echelon — OR trend, TMDE calibration posture, LRU float, CECOM support tempo.
• 04Run a brigade-level electronic systems maintenance posture during a real-world deployment or major exercise — Tobyhanna depot reach-back, CECOM LAR interface, contractor field-service employment.
• 05Translate the Army's sustainment doctrine and CECOM/Tobyhanna modernization guidance into enlisted-talent decisions at the unit.
• 06Walk the line during the brigade CMDP inspection and identify broken calibration programs, ESD compliance gaps, and documentation failures 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).
• —CECOM, Tobyhanna Army Depot, 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 — 948B / 948E 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 maintenance-risk call. Take the disagreement in the office; walk out aligned.
• —Confusing seniority with technical depth. The Army keeps senior maintenance NCOs who hire, promote, and mentor technicians 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 948B / 948E warrant slate conversation as transactional. The warrant career is one of the most consequential technical careers in the Army; mentor it like it is.
• —Stopping personal physical training because you are "too senior, too shop-floor." Soldiers stop respecting the diamond when the body stops carrying it.

The good electronics 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 948B/948E 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 deploys for the worst rotation on the calendar, the BCT commander sleeps because he knows the senior electronics maintenance NCO walking the shop floor at 0200 is this one.
