Field Artillery Fire Control Marine

You are the FDC computer. The firing data that leaves your station is what the gun line or launcher crew uses to put steel on target — and if you compute it wrong, the round lands on friendlies. This is the most safety-critical junior enlisted billet in field artillery.

You arrive at your firing battery from the FA Fire Control course at Fort Sill — a joint course with Army students — and the FDC chief puts you on the AFATDS terminal or the manual plotting board, depending on what the battery is training on that week and whether the digital system is up. In garrison you train on fire mission processing — receiving calls for fire, extracting target grid and description, computing firing data (deflection, elevation, charge, fuze), and transmitting fire commands to the gun line or launcher section. You learn the manual backup procedures on the M16/M19 plotting board and the firing tables because AFATDS goes down, and when it does, the battery still has to shoot. You run meteorological data corrections, maintain the safety template, verify every fire mission against the no-fire areas and restricted fire areas on the fire support coordination overlay, and you pull your share of the working parties and generator maintenance that keep the FDC tent running. In the field you process fire missions under time pressure and under the FDC chief's direct supervision — and you learn fast that the gun line fires what you give them, so you had better give them the right data.

• 01Process a call for fire from receipt through firing data computation on AFATDS — target grid, target description, munition selection, charge computation, deflection, elevation, fuze setting — and transmit the fire command to the gun line within the battery's time standard.
• 02Compute firing data manually on an M16 or M19 plotting board using the current firing tables when AFATDS is degraded or offline — the manual backup is not optional, it is the standard you will be tested against.
• 03Apply meteorological data corrections to firing data using the MDAC (Meteorological Data Analysis Computer) or manual met correction tables — non-standard conditions change where the round lands, and the FDC that ignores met data misses the target.
• 04Verify every fire mission against the safety template and the current fire support coordination measures — no-fire areas, restricted fire areas, boundaries, coordinated fire lines — before transmitting the fire command. This is the safety check that prevents fratricide.
• 05Zero and qualify the M27 IAR or M4 to the Annual Rifle Training (ART) standard — Expert is the floor; every 0844 is a Marine first, and the FDC defends its own position.
• 06Run a TCCC casualty assessment — MARCH-PAWS — and apply a CAT tourniquet under fire, because the FDC is a high-value target and you may be the closest treatment tier.

• —FM 3-09 — Field Artillery Operations and Fire Support (the doctrinal reference for every fire mission procedure, every safety check, and every fire support coordination measure your FDC operates within).
• —NAVMC 3500.44 — Marine Corps Artillery Training and Readiness Manual (the individual and collective tasks for 08-series artillery Marines, including FDC fire control).
• —MCWP 3-15 — Marine Corps Fire Support (the USMC-specific fire support doctrine — fire support coordination measures, target engagement authority, and the clearance-of-fires chain that your safety template enforces).
• —TM 6-230 — Firing Tables (the reference for manual computation of firing data when AFATDS is offline — the FDC chief will quiz you on charge-to-range relationships).
• —MCO 6100.13 — Marine Corps Physical Fitness, Body Composition, and Military Appearance (your PFT/CFT standard).

• —1st-Class PFT and CFT — the FDC displaces with the battery; fitness is operationally relevant.
• —Annual Rifle Qualification: Expert is the floor. Every 0844 is a Marine first.
• —Process a fire mission on AFATDS and on the manual plotting board within the battery's time standard — the FDC chief tests both, and the manual standard is not relaxed because "AFATDS was working last time."
• —MCMAP Gray Belt before LCpl; Green Belt before you sit a Corporals Course board.
• —Zero safety template violations on any fire mission you process — one fire command transmitted without a safety check is a potential fratricide with your name on the data.

• —Transmitting a fire command without verifying it against the safety template. The safety template is not a formality — it is the physical check that prevents the round from landing inside the no-fire area where friendly forces are operating. Skip it once and the investigation has your name on every page.
• —Entering the target grid incorrectly into AFATDS and not catching it before the fire command goes out. A transposed digit in a six- or eight-digit grid moves the round hundreds or thousands of meters — and the gun line fires what you tell them to fire.
• —Treating manual computation as an obsolete skill because "AFATDS is always up." AFATDS goes down in the field — power failures, software faults, electromagnetic interference. The FDC that cannot compute manually is a battery that cannot shoot, and the battery that cannot shoot is not protecting anyone.
• —Failing to apply meteorological corrections when the met data is available. Non-standard atmospheric conditions — temperature, pressure, wind — move the round off the intended target. The FDC that ignores met data is firing with less accuracy than it could, and accuracy is the entire job.
• —Posting any information about fire missions, target lists, fire support coordination measures, or FDC procedures on social media. FDC data is a high-value intelligence indicator — the adversary who knows your no-fire areas knows where your forces are.

The good junior fire control Marine is the one the FDC chief can put on the AFATDS terminal during a night fire mission and trust that every fire command will be computed correctly, checked against the safety template, and transmitted to the gun line without a data error. By month nine the FDC chief is letting him process fire missions without direct supervision on the standard targets; by the LCpl evaluation cycle the battery gunny knows exactly who is going to the Corporals Course slate and who is ready for more complex missions.

You are an NCO in the Fire Direction Center. In this Corps the chevron means it the first time you pin it — Cpl in the FDC means you are the Marine who checks the other computer's work, verifies the safety template application, and refuses to let a fire command leave the tent until the data is right. The gun line trusts the FDC with their reputation and the maneuver element trusts you with their lives.

You are the senior computer or FDC section NCO — three to five Marines in the fire direction team plus yourself — and you are responsible for their training, their accuracy, and the speed of fire mission processing. You verify every fire command the junior computers produce before it goes to the gun line, maintain the safety template and the fire support coordination overlay, run the AFATDS check-fire and cancel-fire procedures when the mission changes mid-execution, and train the junior Marines on manual computation until they can do it cold. You write proficiency and conduct marks for your Marines and you are the Marine the FDC chief relies on when he is at the battery commander's planning conference. You are also watching your own Sgt timeline — Corporals Course is gated, the cutting score moves, and the fire control Marine who understands target acquisition integration and fire support planning beyond the FDC terminal is the one the battery commander promotes.

• 01Verify every fire command produced by the junior computers before transmission — deflection, elevation, charge, fuze, target grid, safety template compliance — as the independent check that catches the errors the original computer missed.
• 02Maintain the safety template and fire support coordination overlay in real time — update no-fire areas, restricted fire areas, coordinated fire lines, and friendly unit positions as they change during operations, and verify that every computer has the current measures.
• 03Run AFATDS check-fire and cancel-fire procedures when a mission changes mid-execution — the procedure that stops a round from going downrange when the target picture changes is time-critical and you execute it without hesitation.
• 04Train junior computers on manual plotting board computation to the battery's time standard — charge-range relationship, firing table application, met correction, deflection-elevation computation — until they can process a fire mission manually without coaching.
• 05Operate battery-net radios — PRC-117G, PRC-152, PRC-153 — and receive and transmit calls for fire, fire commands, and fire support coordination measure updates in the standard format.
• 06Process complex fire missions — time-on-target, coordinated illumination, danger-close, immediate suppression — on AFATDS and on the manual board under the FDC chief's supervision.

• —FM 3-09 — Field Artillery Operations and Fire Support (you now understand the full fire mission chain from the observer through the FDC to the gun line — and you can explain why every safety check exists).
• —NAVMC 3500.44 — Marine Corps Artillery T&R Manual (FDC section NCO collective tasks; you run training against this and sign your computers' CARPs).
• —MCWP 3-15 — Marine Corps Fire Support (fire support coordination measures you maintain on the overlay; the FSO references this when briefing the FDC on no-fire areas and boundaries).
• —TM 6-230 — Firing Tables (you teach from these now; the junior computers need to understand charge-range relationships from the table, not just from AFATDS).
• —MCO 1610.7 — Performance Evaluation System (you write proficiency and conduct marks now; the FitRep is coming).
• —MCO 1400.32 — Marine Corps Promotion Manual (composite scores and cutting scores for 0844 to Sgt).

• —Corporals Course graduate — required and gated; the Sgt board does not wait for your schedule.
• —Green Belt MCMAP minimum; Brown Belt is what the FDC chief notes on the FitRep going to the Sgt board.
• —1st-Class PFT and CFT — the FDC displaces with the battery and the NCO who cannot carry the load loses credibility before the first fire mission.
• —Composite score tracked monthly in TFRS; pull the current cutting score for 0844 to Sgt before asking the FDC chief where you stand.
• —Zero fire commands transmitted without safety template verification under your watch — the Cpl who lets a bad fire command leave the FDC because the timeline was tight owns the result.

• —Letting a fire command go to the gun line without your independent verification because the junior computer "looked confident." The independent check exists because humans make data entry errors under time pressure — your job is to catch them, and "I trusted him" does not survive the investigation into a short round.
• —Failing to update the fire support coordination overlay when a measure changes during operations. A no-fire area that moved two hours ago but is still in its old position on your overlay is a fratricide waiting to happen.
• —Skipping the manual computation training because "AFATDS handles it." The FDC that loses AFATDS mid-mission and cannot switch to manual plotting boards loses the battery's ability to shoot — and that is your section's failure.
• —Treating the FDC safety procedures as a speed bump rather than a load-bearing wall. The battery commander will never complain that you delayed a fire command by 15 seconds to verify the safety template. He will always investigate when a round lands inside the no-fire area.
• —Allowing junior computers to process fire missions without the section NCO's eyes on the safety template check. The computer who transmits a fire command that violates the safety template is wrong; the section NCO who was not supervising is worse.

The good Cpl 0844 is the FDC section NCO the chief sends to the alternate FDC position with two junior computers and trusts to process fire missions accurately, check every fire command against the safety template, and transmit correct firing data to the gun line — without a radio call asking "did you check the NFAs?" His computers are training on manual plotting boards during garrison weeks and the FDC chief has already mentioned his name to the battery gunny for the next Sgt board.

The Fire Direction Center is yours. Three to six Marines, AFATDS, the plotting boards, the met station, the safety templates, and the fire support coordination overlay. Every round the battery fires is a product of the data your FDC computed and the safety checks your FDC applied. If the data is wrong, the round is wrong, and the investigation starts in your tent.

You run the FDC — three to six Marines, AFATDS, manual plotting boards, and the met station — and you are responsible for their training, their accuracy, and the safety of every fire mission the battery executes. You receive calls for fire from the forward observers and the fire support coordinator, prioritize and assign fire missions to your computers, verify the firing data and safety template compliance before the fire command goes to the gun line, and coordinate with the target acquisition section on radar-acquired targets entering the fire mission chain. You write FitReps on your Cpls under MCO 1610.7, manage the AFATDS system configuration and software currency, and brief the battery commander or XO on FDC readiness at every planning event. In garrison you build the FDC training schedule against NAVMC 3500.44 collective tasks, run fire mission processing drills with increasing complexity, and mentor your section NCOs toward Sergeants Course readiness. You are also the Marine who manages the fire support coordination overlay for the battery — the overlay that prevents friendly-fire incidents is your product, and you own its accuracy.

• 01Manage the FDC through a multi-mission fire sequence — prioritize targets, assign missions to computers, verify firing data, apply safety checks, transmit fire commands to the gun line, and track missions through post-fire assessment — for multiple fire missions simultaneously without losing track of any mission.
• 02Maintain and update the fire support coordination overlay with current measures — no-fire areas, restricted fire areas, coordinated fire lines, fire support coordination lines, boundaries, and friendly unit positions — and verify that every computer in the FDC has the current measures before any fire mission is processed.
• 03Write FitReps on your section NCOs per cycle under MCO 1610.7 — observed behavior, action-result-impact, defensible relative value — that the reporting senior can defend.
• 04Run a danger-close fire mission to the MCWP 3-15 standard — risk estimate distance, commander's acceptance of risk, modified safety procedures — without hesitation and without error, because the Marines on the ground are counting on accuracy measured in meters.
• 05Manage the AFATDS system configuration, troubleshoot software faults, and execute the degraded-operations switchover to manual plotting boards when the digital system fails.
• 06Mentor your section NCOs into Sergeants Course-ready candidates with both digital and manual fire control depth and fire support coordination understanding.

• —FM 3-09 — Field Artillery Operations and Fire Support (you own the fire mission processing standard for the battery; the battery commander evaluates the FDC against this doctrine).
• —NAVMC 3500.44 — Marine Corps Artillery T&R Manual (FDC chief-level collective tasks; the battery commander evaluates your FDC against this).
• —MCWP 3-15 — Marine Corps Fire Support (the fire support coordination framework — every coordination measure, every clearance-of-fires procedure, every danger-close standard lives here, and you enforce all of them).
• —TM 6-230 — Firing Tables (the manual computation reference your FDC falls back on when AFATDS is offline — you teach from these and test your computers against them).
• —MCO 1610.7 — Performance Evaluation System (you write FitReps for your section NCOs now).
• —MCO 1400.32 — Marine Corps Promotion Manual (SSgt board mechanics, composite scores, 0844 MOS roadmap).

• —Sergeants Course graduate — required and gated.
• —Brown Belt MCMAP minimum; Black Belt is what the battery gunny notes going to the SSgt board.
• —FDC processing time at or below the battery standard for every fire mission type — the time from call-for-fire receipt to fire command transmission is tracked and the FDC chief knows his section's average.
• —Zero safety template violations on any fire mission processed under your FDC chief authority — one fire command that violates a fire support coordination measure is a potential fratricide with the FDC chief's name on the data.
• —Composite score tracked monthly; pull the current MARADMIN cutting score for 0844 to SSgt before asking the battery gunny where you stand.

• —Verbal counseling only. If it is not in writing — page-11 entry or formal counseling — it did not happen and the company commander cannot defend you when it matters.
• —Processing a danger-close mission without personally verifying the risk estimate distance and the commander's acceptance of risk. Danger-close means friendly forces are inside the minimum safe distance — the FDC chief who delegates this check to a junior computer is gambling with lives he does not have the authority to gamble with.
• —Allowing the fire support coordination overlay to become stale during operations. Coordination measures change as the maneuver element moves — the FDC chief who is working off yesterday's overlay is the FDC chief who clears a fire mission into a no-fire area that was established two hours ago.
• —Hiding an AFATDS system fault from the battery commander to avoid the conversation about manual backup. The battery commander needs to know the FDC is operating in degraded mode — he adjusts his expectations and his fire support plan accordingly.
• —Doing the fire mission processing yourself instead of teaching the section NCO to do it. The FDC will fail when you go to Sergeants Course, and you will be the reason.

The good Sgt 0844 is the FDC chief the battery commander trusts with the most complex fire mission on the target list — time-on-target with a coordinated illumination event and a danger-close restriction — and knows the firing data will be correct, the safety template will be checked, and the fire command will reach the gun line before the timeline expires. His section NCOs are Sergeants Course-ready, his computers can process fire missions on the manual plotting board without coaching, and the fire support officer trusts the FDC enough to clear fires without a verification call-back.

You are the senior fire direction SNCO or the fire control platoon sergeant. Whether you are running the battery FDC as the senior enlisted in the tent or managing the fire direction training program across the battery, the accuracy of every round the battery fires and the safety of every fire mission traces through your hands.

You run the battery FDC as the senior enlisted fire direction SNCO — or serve as the platoon sergeant for the fire control section — managing three to five FDC chiefs and their computers across the main and alternate FDC positions. You write three to four Sgt FitReps per cycle, build the FDC training schedule against NAVMC 3500.44 collective tasks, brief the battery commander on FDC readiness and fire mission processing quality at every planning event, and manage the AFATDS system configuration and software currency across the battery. You coordinate with the target acquisition section on radar-to-FDC data integration, with the supported maneuver element's fire support officer on coordination measures and clearance of fires, and with the battalion FDC on target deconfliction and fire support coordination at echelon. You set the safety template standard across the battery — the template that prevents fratricide is your product, and every FDC chief enforces your standard.

• 01Manage the battery FDC through a battalion-level fire mission exercise or deployment — multiple simultaneous fire missions across main and alternate FDC positions, target prioritization, fire support coordination measure updates, danger-close missions, met corrections — with the battery XO watching the processing timeline.
• 02Write three to four Sgt FitReps per cycle under MCO 1610.7 that the reporting senior can defend at the battalion FitRep review.
• 03Coordinate with the supported maneuver element's fire support officer on clearance of fires, coordination measure updates, and target deconfliction — the FSO trusts your FDC because you ensure the coordination overlay is current and the safety procedures are enforced.
• 04Manage the AFATDS system configuration across the battery — software currency, network architecture, data exchange protocols with the battalion FDC and the target acquisition section — and execute the degraded-operations plan when digital systems fail.
• 05Mentor two to three Sgts into Career Course graduates and SSgt-board-ready candidates with both digital and manual fire control depth.
• 06Brief the battery commander honestly on FDC readiness, processing accuracy, safety template compliance trends, and the second-order effects of operations tempo on fire control crew proficiency.

• —FM 3-09 — Field Artillery Operations and Fire Support (you operate at the battery and battalion fire direction integration level; understanding the full call-for-fire-to-impact chain, target engagement authority, and fire mission processing doctrine is your primary responsibility).
• —NAVMC 3500.44 — Marine Corps Artillery T&R Manual (battery FDC collective standards you build training against).
• —MCWP 3-15 — Marine Corps Fire Support (the fire support coordination framework for the MAGTF; you enforce this across every FDC position in the battery).
• —TM 6-230 — Firing Tables (you own the manual computation standard for the battery; every FDC chief trains against the tables you set).
• —MCO 1610.7 — Performance Evaluation System (FitRep policy for the Sgts and FDC chiefs you rate).
• —MCO 1400.32 — Marine Corps Promotion Manual (SSgt-to-GySgt board mechanics, FitRep relative value impact, 08xx MOS roadmap).

• —Career Course (resident or distance) completed; SNCO Academy slot for GySgt-level resident as soon as the board signals.
• —Black Belt MCMAP — the battery expects the senior fire direction SNCO to be a senior instructor.
• —FDC processing time at or below the battery standard across all FDC positions — the processing time from call-for-fire receipt to fire command transmission is your metric and the battery commander watches it.
• —Zero safety template violations across the battery during your tenure — the standard you set for safety template compliance is the standard every FDC chief enforces.
• —FitRep relative value above battalion average — one weak cycle on the SSgt-to-GySgt board moves the timeline by years.

• —Delegating fire support coordination measure updates to FDC chiefs without verifying receipt and application. A no-fire area that the FDC chief "updated" but the computers on shift do not have is a fratricide waiting for the next fire mission.
• —Writing a FitRep as a wish list instead of an evaluation. The reporting senior who defends an inflated Sgt at the battalion FitRep board remembers the SSgt who wrote it.
• —Allowing AFATDS software currency to lag behind the battalion standard. An FDC whose AFATDS version cannot exchange fire missions with the battalion FDC is a fire direction failure with the SSgt's name on the readiness report.
• —Treating the main and alternate FDC as one trained and one backup. Both FDC positions must be fully trained and capable of processing the full target list independently — the SSgt who only invested in training the main FDC crew discovers the problem when the main position is destroyed and the alternate cannot process.
• —Hiding an FDC readiness gap from the battery commander before the exercise. The battery commander finds out from the battalion fires officer when the target assignment comes in and the FDC cannot process at the required rate.

The good SSgt 0844 is the senior fire direction SNCO the battery commander walks out of the operations order brief and trusts that every FDC position is manned, the safety template is current, the coordination measures are applied, and the fire commands reaching the gun line are accurate enough to fire without a verification delay. His FDC chiefs are Career Course-ready with both digital and manual depth, and the battalion fires officer knows his name before the battery commander introduces him.

You are the battery gunny or the battalion fire direction chief. Every round the battery fires correctly, every fire mission processed accurately, and every safety template that prevents fratricide traces back to the standard you set, the training you built, and the fire control Marines you developed.

You run the battery's enlisted side as the battery gunnery sergeant — 40 to 80 Marines across FDC sections, gun line or launcher sections, the maintenance section, and the battery trains — or serve as the battalion fire direction chief, the billet that owns the fire direction integration across the battalion's batteries and coordinates with the regimental or MEF fires section on target deconfliction and fire support coordination at echelon. As battery gunny you write three to five SSgt FitReps per cycle that feed the GySgt board, brief the battery commander on enlisted readiness, FDC processing quality, and safety compliance at every BUB, and manage the FDC training program across the battery. You mentor two or three SSgts toward Career Course graduation and GySgt-board readiness, set the standard for fire mission processing accuracy and safety template compliance across the battery, and carry the honest read on which Sgts are FDC-chief caliber and which ones are better employed on the gun line or target acquisition side. At the battalion fire direction chief level you coordinate with the MEF fires section, the direct-support battalion FDC, and the supported maneuver elements' fire support officers on target deconfliction and fire support coordination.

• 01Brief the battery commander on FDC readiness, fire mission processing accuracy, safety template compliance, and known fires integration risks at every BUB — before the CO has to ask.
• 02Write three to five SSgt FitReps per cycle under MCO 1610.7 that the battalion FitRep board can defend — clean attribute rationale, defensible relative value.
• 03Manage the battery's full FDC training program — fire mission processing drills, manual backup exercises, safety template certification, met data application training — and deliver proficiency assessments to the battery commander on the cycle he sets.
• 04Mentor two to three SSgts into Career Course graduates and GySgt-board-ready candidates with honest reads on who is troop-leadership track and who is the fire direction SME the MMPB needs at the MEF fires section.
• 05Coordinate with the battalion FDC, the regiment fires section, and the MEF fires SNCO on target deconfliction, fire support coordination at echelon, and the fire direction integration architecture that connects the battery's FDC to the joint fires network.
• 06Brief the battalion SgtMaj and the battery commander honestly on battery morale, fire control crew proficiency, retention, and the second-order effects of operations tempo on FDC accuracy.

• —FM 3-09 — Field Artillery Operations and Fire Support (you operate at the regimental and MEF fire direction integration level; this is the doctrinal spine of every fires integration brief you give).
• —NAVMC 3500.44 — Marine Corps Artillery T&R Manual (battery-level collective standards; the battery commander evaluates the battery's fire direction proficiency against this at every evaluation event).
• —MCWP 3-15 — Marine Corps Fire Support (the fire support coordination framework for the MAGTF; you own the fire support coordination overlay standard across the battery and brief the FSO against this).
• —TM 6-230 — Firing Tables (you own the manual computation standard for the battery; the FDC chiefs train against the standard you set from these tables).
• —MCO 1610.7 — Performance Evaluation System (FitRep mechanics you now teach to your SSgts).
• —MCO 1400.32 — Marine Corps Promotion Manual (GySgt-to-MSgt / 1stSgt board mechanics and 08xx MOS roadmap).

• —SNCO Academy Advanced Course (Career Course) graduate; SNCO Academy Senior Course slated as the MSgt board approaches.
• —Black Belt Instructor (MCMAP) — you are a senior instructor at the battery or battalion level.
• —Battery FDC processing accuracy and speed at or above the battalion standard through the full operations cycle — the fire mission processing rate is your metric.
• —FitRep profile that the senior reporting official can defend at the MSgt / 1stSgt board — relative value, attribute rationale, all aligned.
• —1st-Class PFT and CFT; the battery watches the battery gunny's scores more carefully than anyone's except the 1stSgt's.

• —Allowing safety template compliance to become a check-the-box exercise rather than a real safety verification. The battery where FDC computers sign the safety template without actually verifying the fire mission against the coordination measures is the battery that fires into a no-fire area — and the battery gunny who allowed the culture owns the result.
• —Confusing being tight with the battery commander with being aligned with the battery commander. The battery needs you to push back on a fires plan you know exceeds the FDC's processing capacity — in his office, with the door closed.
• —Carrying a gun-line vs. FDC preference into the battery gunny billet. The battery gunny who over-invests in one side produces a battery where the other side knows it — and fire direction accuracy is not the place to cut corners.
• —Allowing AFATDS software currency to lag behind the version the supported battalion is running. An FDC whose AFATDS version cannot exchange fire missions with the supported unit's FDC is a fires integration failure with the battery gunny's name on it.
• —Stopping personal PT because you are too senior. Marines stop respecting the chevrons when the body stops carrying them, and the 1st-Class PFT is still the bar.

The good GySgt 0844 is the battery gunny the battalion fires officer can brief a fires support plan to on Monday and trust that the FDC is processing accurately, the safety templates are current, the manual backup is trained, and the fire commands reaching the gun line are correct. His SSgts are Career Course-ready with both digital and manual depth, his Marines re-enlist because of the technical credibility and the training standard, and the regiment fires SNCO is already mentioning his name for the MSgt or 1stSgt slate before the board convenes.

You are the standard-bearer for fire direction. Every fire mission processed correctly, every safety template that prevented a fratricide, and every FDC that switched to manual backup without losing a beat traces back to a standard you set and a Marine you developed.

As 1stSgt you run the firing battery — 80 to 150 Marines, the battery office, the FDC chiefs and section chiefs, the training calendar, and the boundary between what the battery commander needs and what the battery can deliver in fire direction accuracy and safety. As MSgt you are the senior fire direction SME at the battalion, regimental, or MEF fires section — fire direction integration chief, AFATDS architecture owner, or the senior enlisted who shapes the next generation of 0844 GySgts and battery gunnies. As SgtMaj you advise the battalion or regimental commander on every enlisted decision in the fires community and you set the standard for how fire control Marines are developed, employed, and retained across an entire echelon. As MGySgt you are the occupational pinnacle of the fire control field — the Marine the HQMC fires community calls when the 0844 MOS structure, the fire direction T&R program, or the AFATDS integration doctrine needs an enlisted practitioner's voice. You write fewer FitReps but the ones you write determine the next battery gunny, 1stSgt, and MSgt slates.

• 01Run a 1stSgt's call that handles accountability, sick call, discipline, family readiness, training calendar, and FDC readiness status in 30 minutes flat — without the battery gunny running to fill the gaps.
• 02Build a firing battery quarterly training schedule with the battery commander and the operations officer that builds fire mission processing proficiency and manual backup readiness without burning the FDC crews out on a tempo that produces accuracy errors.
• 03Mentor four GySgts and the senior SSgts as the next 1stSgt / MSgt cohort — honest reads on who is troop-leadership track and who is the fire direction SME the MMPB needs at the MEF fires section or HQMC fires community.
• 04Walk the FDC during a live-fire evaluation or major exercise and identify the processing errors, the safety template gaps, and the coordination measure failures before the evaluators do.
• 05Brief the battalion or regimental commander and the BSgtMaj on battery morale, fire control crew proficiency, FDC readiness, and the second-order effects of fire direction decisions they cannot see from the operations center.
• 06Run a Red Cross or casualty notification with the dignity the family and the formation require — you are the face they remember.

• —MCDP 1 — Warfighting; MCDP 1-3 — Tactics (you teach these to the next generation of fire control Marines; the FDC computer who understands maneuver is the one who understands why the safety template is not negotiable).
• —FM 3-09 — Field Artillery Operations and Fire Support; MCWP 3-15 — Marine Corps Fire Support (you are the practitioner the doctrine team calls when the fire direction integration revision cycle starts).
• —MCO 1610.7 — Performance Evaluation System (you are the rater or reviewing officer on the FitReps that determine the next 0844 GySgt and 1stSgt slates).
• —MCO 1400.32 — Marine Corps Promotion Manual (1stSgt / SgtMaj / MSgt / MGySgt board mechanics and 08xx MOS roadmap).
• —MCO 1900.16 — Marine Corps Retirement / Separation (you are the resource the formation comes to for transition questions).
• —The Commandant's Reading List and current Planning Guidance — you translate strategic intent down to the computer running the safety template check in the dark.

• —SNCO Academy Senior Course graduate; Sergeants Major Course (Marine Corps University, Camp Geiger NC) before competing for command SgtMaj slate.
• —Battery UCMJ rate, retention rate, and SAPR/EO climate index in the top tier of the battalion — the BSgtMaj reports up against every peer 1stSgt.
• —Battery FDC processing accuracy and safety template compliance at or above the battalion standard through every inspection and major training event during your tenure.
• —Zero senior-enlisted-level integrity incidents — financial, fraternization, OPSEC. One ends the career permanently at this rank and the Corps does not relitigate.
• —Post-service transition plan running 24 to 36 months out — VA disability claim filed pre-EAS, SkillBridge slot identified, retirement not walked into cold.

• —Going public with disagreement with the battery commander. You take the disagreement in his office with the door closed; you walk out aligned, every time.
• —Confusing seniority with leverage. The Corps keeps senior enlisted who serve the formation — not the ones who run their own program off the commander's back.
• —Stopping personal PT because you are too senior. Marines stop respecting the chevrons when the body stops carrying them, and the 1st-Class PFT is still the bar.
• —Letting a battery gunny run a safety template compliance culture that is paperwork rather than execution. The FDC that signs the safety template check without actually verifying the fire mission against the coordination measures is the FDC that fires into the no-fire area — and the 1stSgt who looked the other way owns part of that.
• —Confusing the warm-up to retirement with the job. Until you walk out of the formation for the last time, the formation is your job — the fire control Marines are still watching how you carry it.

The good 1stSgt / SgtMaj 0844 is the senior Marine every fire control Marine in the battery knows by face and reputation. He is the reason the re-enlistment line forms after a hard deployment where every fire mission mattered and the safety standard never slipped. The battery commander trusts him with the worst news at 0200; the Marines trust him to fight for the training time, the equipment upgrades, and the career decisions before walking away from what he cannot win. The good MGySgt is the Marine the HQMC fires community calls when the fire direction T&R program needs rewriting — and the FDC chiefs across the MEF quote him at fire mission processing drills without realizing they are doing it.
