Field Artillery Sensor Support Marine

You are the sensor support Marine. The radar sees one thing, the UAS sees another, and the SIGINT feed says something else — your job is to take all of it, make sense of it, and hand the targeting section a picture that is accurate enough to put fires on the right enemy position.

You arrive at your artillery battalion's targeting or sensor support section from the FA Sensor Support course at Fort Sill and the section chief puts you to work consolidating sensor data into a format the targeting section and the FDC can use. In garrison you train on the D3A (Decide-Detect-Deliver-Assess) targeting cycle and the F3EAD (Find-Fix-Finish-Exploit-Analyze-Disseminate) methodology, learn the capabilities and limitations of the sensors your battalion employs — counter-battery radar, UAS feeds, acoustic sensors, SIGINT reporting — and practice integrating sensor data into AFATDS and the targeting products the battalion fires officer needs. You maintain the sensor status boards, track which sensors are active and in what sectors, input sensor reports into the common operational picture, and pull your share of the working parties and motor-pool details that hold the section together. In the field you monitor sensor feeds, consolidate incoming reports, cross-reference sensor data against known targets and the high-payoff target list, and pass targeting recommendations to the section chief. The honest reality: this is an integration MOS, not a single-system MOS — your value is in connecting the sensors to the shooters, and nobody notices when you do it right, but everybody notices when you miss one.

• 01Consolidate sensor data from multiple sources — counter-battery radar acquisitions, UAS imagery and video feeds, acoustic sensor reports, SIGINT indicators — into a single targeting product the fires officer and the FDC can act on.
• 02Operate AFATDS at the sensor interface level — input sensor reports, update target lists, track sensor coverage sectors, and generate sensor status reports for the targeting section chief.
• 03Apply the D3A (Decide-Detect-Deliver-Assess) targeting cycle framework to incoming sensor data — match sensor detections against the high-payoff target list, determine whether the detection meets the attack criteria, and recommend delivery assets.
• 04Maintain sensor status boards and coverage overlays — which sensors are active, what sectors they cover, what gaps exist, and what the gaps mean for the supported maneuver element's force protection.
• 05Zero and qualify the M27 IAR or M4 to the Annual Rifle Training (ART) standard — Expert is the floor; every 0847 is a Marine first.
• 06Run a TCCC casualty assessment — MARCH-PAWS — and apply a CAT tourniquet under fire, because the sensor section may be collocated with the battalion COC, which is a targeting priority.

• —FM 3-09 — Field Artillery Operations and Fire Support (the doctrinal framework for how sensor data enters the fires chain and the targeting cycle that your section supports).
• —JP 3-60 — Joint Targeting (the joint targeting doctrine that defines D3A and F3EAD — the targeting methodologies your section operates within).
• —NAVMC 3500.44 — Marine Corps Artillery Training and Readiness Manual (the individual and collective tasks for artillery Marines, including sensor support billets).
• —MCWP 3-15 — Marine Corps Fire Support (the USMC fire support coordination doctrine your section supports — how sensors feed the fire support plan and the targeting process).
• —MCO 6100.13 — Marine Corps Physical Fitness, Body Composition, and Military Appearance (your PFT/CFT standard).

• —1st-Class PFT and CFT — the sensor section moves with the battalion COC; fitness is operationally relevant.
• —Annual Rifle Qualification: Expert is the floor. Every 0847 is a Marine first.
• —Process a sensor report and update the target list within the section's time standard — a sensor detection that sits in the queue for 30 minutes is a missed engagement opportunity.
• —MCMAP Gray Belt before LCpl; Green Belt before you sit a Corporals Course board.
• —Maintain the sensor status board and coverage overlay accurately — the section chief should never discover a sensor coverage gap from the fires officer before hearing it from you.

• —Failing to cross-reference a sensor detection against the known friendly positions before recommending it as a target. An acoustic detection or radar acquisition that turns out to be a friendly unit is a fratricide recommendation — and the sensor support Marine who passed it forward without checking owns the error.
• —Sitting on a sensor report because you were not sure how to classify the detection. A delayed sensor report loses its tactical value — the enemy fires position you detected 30 minutes ago has displaced, and the counter-battery mission fires on an empty grid.
• —Treating sensor data from different sources as equally reliable without understanding their limitations. A radar acquisition has a different accuracy and confidence level than an acoustic detection or a SIGINT indicator — the sensor support Marine who treats them all the same produces a target list the fires officer cannot trust.
• —Failing to update the sensor coverage overlay when a sensor goes offline. The fires officer who thinks the northern sector is covered by radar when the radar went offline an hour ago is making force protection decisions based on information you should have updated.
• —Posting any information about sensor types, capabilities, coverage sectors, or targeting data on social media. Sensor employment data tells the adversary where you can see them and where you cannot.

The good junior sensor support Marine is the one the section chief can put on the sensor integration station during a targeting cycle and trust that every sensor report will be consolidated accurately, cross-referenced against known friendlies, checked against the high-payoff target list, and passed to the targeting section in a format they can act on. By month nine the section chief is letting him update the target list independently; by the LCpl evaluation cycle the battery gunny knows who is going to the Corporals Course slate.

You are an NCO. In this Corps the chevron means it the first time you pin it — Cpl in the sensor support section means you are the Marine who checks the targeting product before it goes to the fires officer, verifies that the sensor data has been cross-referenced, and refuses to pass a recommendation forward until the picture is right.

You are the section NCO or senior sensor support Marine — two to four Marines plus yourself — and you are responsible for their training, their sensor integration proficiency, and the accuracy of every targeting product the section produces. You verify the sensor data consolidation your junior Marines produce before it goes to the targeting section, maintain the high-payoff target list and the sensor-to-target pairing matrix, train the juniors on sensor capabilities and limitations, and operate the AFATDS sensor interface at the journeyman level. You write proficiency and conduct marks for your Marines and you are the Marine the section chief relies on when he is at the fires officer's targeting meeting. You are also developing your understanding of the broader targeting architecture — how sensor data feeds through the D3A and F3EAD cycles, how the fires officer prioritizes targets, and how your section fits into the joint fires kill chain at battalion and regimental level.

• 01Verify the sensor data consolidation and targeting recommendations produced by junior Marines — cross-reference against known friendly positions, check sensor confidence levels, confirm that the detection meets the high-payoff target list attack criteria — before the product goes to the fires officer.
• 02Maintain the high-payoff target list and the sensor-to-target pairing matrix — which sensors are tasked against which named areas of interest, which targets have been detected, and which gaps require additional sensor allocation.
• 03Operate AFATDS at the sensor integration level — manage the sensor interface, input targeting data, generate sensor coverage analyses, and produce targeting products for the fires officer's targeting meeting.
• 04Train junior sensor support Marines on the capabilities, limitations, and employment characteristics of the sensors the battalion employs — radar detection ranges, UAS coverage sectors, acoustic sensor sensitivity, SIGINT indicators — so they can assess the reliability of each sensor report.
• 05Brief the section chief or the fires officer on sensor coverage status, detected targets, coverage gaps, and targeting recommendations in the format the targeting meeting requires.
• 06Operate section-level communications — PRC-117G, PRC-152 — and transmit sensor reports and targeting updates in the standard format.

• —FM 3-09 — Field Artillery Operations and Fire Support (you now understand the full targeting chain from sensor detection through fire mission execution — and you can explain how each sensor fits).
• —JP 3-60 — Joint Targeting (D3A and F3EAD targeting methodologies at the joint level; you operate within these frameworks).
• —NAVMC 3500.44 — Marine Corps Artillery T&R Manual (sensor support section NCO collective tasks; you run training against this).
• —MCWP 3-15 — Marine Corps Fire Support (the fire support coordination framework your section supports — how sensor data integrates with the fire support plan).
• —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 0847 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 section chief notes on the FitRep going to the Sgt board.
• —1st-Class PFT and CFT — the sensor section moves with the COC.
• —Composite score tracked monthly in TFRS; pull the current cutting score for 0847 to Sgt before asking the section chief where you stand.
• —Zero targeting recommendations passed to the fires officer without section NCO verification — the section NCO who lets a bad target recommendation go forward because the junior Marine "seemed sure" owns the result.

• —Passing a targeting recommendation to the fires officer without verifying the sensor data against the known friendly positions overlay. The recommendation that turns out to be a friendly unit is a fratricide recommendation — and the section NCO who did not verify owns the error.
• —Failing to update the sensor-to-target pairing matrix when a sensor is retasked or goes offline. The fires officer who tasks a fire mission against a named area of interest that he believes is covered by radar — when the radar was retasked two hours ago — is acting on information your section should have updated.
• —Treating the sensor integration as a data-entry job instead of an analytical one. The section NCO who enters sensor reports without assessing their reliability, cross-referencing sources, and evaluating whether the detection meets the attack criteria is not doing the job — he is just typing.
• —Allowing junior Marines to pass sensor reports directly to the targeting section without section NCO review. The report that was not verified is the report that generates a fire mission on the wrong target.
• —Sitting on a coverage gap because reporting it makes the section look bad. The fires officer needs to know the gap exists so he can adjust the fire support plan — hiding it makes the plan worse, not the section better.

The good Cpl 0847 is the section NCO the section chief trusts to run the sensor integration station during a battalion targeting cycle and produce a targeting product the fires officer can act on without a call-back. His junior Marines are training on sensor capabilities and targeting methodology during garrison weeks and the section chief has already mentioned his name to the battery gunny for the next Sgt board.

The sensor support section is yours. Two to five Marines, the sensor integration platform, the targeting products, and the fires officer is counting on your section to deliver a picture that is accurate enough to put fires on the right target and keep them off the wrong one.

You run the sensor support section — two to five Marines and yourself — and you are responsible for their training, their analytical proficiency, and the accuracy of every targeting product the section delivers to the fires officer. You manage the sensor-to-target pairing matrix, coordinate with the target acquisition section on radar employment, with the UAS section on ISR coverage, and with the intelligence section on SIGINT and HUMINT indicators. You attend the fires officer's targeting meeting as the sensor subject matter expert, brief sensor coverage status and targeting recommendations, and translate the high-payoff target list into specific sensor tasking. You write FitReps on your section NCOs under MCO 1610.7, build the section training schedule against NAVMC 3500.44 collective tasks, and mentor your NCOs toward Sergeants Course readiness. You are also the link between the sensors and the shooters — when the sensor detects a high-payoff target, you are the Marine who confirms the detection quality, recommends the delivery asset, and passes the target to the FDC for fire mission processing.

• 01Manage the sensor-to-target pairing matrix for the battalion — allocate sensors against named areas of interest, prioritize sensor coverage based on the high-payoff target list, and reallocate sensors when coverage gaps emerge or priorities change.
• 02Attend and brief the fires officer's targeting meeting — sensor coverage status, detected targets, coverage gaps, sensor recommendations, and targeting assessment — in the format the targeting board requires.
• 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.
• 04Coordinate with the target acquisition section, the UAS section, and the intelligence section on sensor employment, ISR coverage, and indicator correlation — the sensor support section chief who works in isolation produces a worse picture than the one who integrates.
• 05Translate the high-payoff target list into specific sensor tasking that is achievable with the sensors available — the fires officer needs recommendations grounded in what the sensors can actually do, not what you wish they could do.
• 06Mentor your section NCOs into Sergeants Course-ready candidates with both sensor employment depth and targeting process understanding.

• —FM 3-09 — Field Artillery Operations and Fire Support (you operate at the battalion targeting level now; understanding the full sensor-to-shooter chain is the section chief's primary responsibility).
• —JP 3-60 — Joint Targeting (D3A and F3EAD at the joint level; you apply these methodologies to the battalion targeting process).
• —NAVMC 3500.44 — Marine Corps Artillery T&R Manual (section-chief level collective tasks; the fires officer evaluates your section against this).
• —MCWP 3-15 — Marine Corps Fire Support (fire support coordination measures and the clearance-of-fires chain your section operates within).
• —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, 0847 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.
• —Sensor coverage of the high-payoff target list at or above the fires officer's requirement — the section chief who cannot cover the priority targets with the sensors available needs to brief the gap, not hide it.
• —Zero targeting recommendations passed to the fires officer without section chief verification — the section chief who lets a bad recommendation go forward owns the fire mission that follows.
• —Composite score tracked monthly; pull the current MARADMIN cutting score for 0847 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.
• —Recommending a sensor allocation you know is unrealistic to impress the fires officer at the targeting meeting. The sensor that you tasked against three NAIs simultaneously covers none of them well — and the fires officer discovers the problem when the detection he was counting on does not arrive.
• —Failing to coordinate with the intelligence section on SIGINT and HUMINT indicators before the targeting meeting. The sensor picture without intelligence context is half the picture — the section chief who shows up to the targeting meeting with sensor data alone and no intelligence correlation is not doing the job.
• —Hiding a sensor coverage gap from the fires officer to avoid the conversation. The fires officer finds out when the high-payoff target in the uncovered NAI fires on the supported unit and no sensor detected it.
• —Doing the sensor analysis yourself instead of teaching the section NCO to do it. The section will miss targets when you go to Sergeants Course, and you will be the reason.

The good Sgt 0847 is the section chief the fires officer trusts to walk into the targeting meeting with a sensor coverage assessment that is honest about gaps, grounded in sensor capabilities, and actionable enough to support fire mission planning. His section NCOs are Sergeants Course-ready, his juniors can correlate multi-source sensor data without supervision, and the FDC chief trusts the targeting products coming out of his section enough to process fire missions without a verification delay.

You are the senior sensor integration SNCO or the targeting SNCO at battalion or regimental level. Whether you are managing the sensor-to-shooter architecture across a battalion frontage or advising the fires officer on targeting integration, the accuracy of the targeting picture and the effectiveness of the battalion's fires program runs through your section.

You serve as the senior sensor integration SNCO at the battalion or regiment — managing the sensor support sections across the formation, coordinating sensor employment with the target acquisition platoon and the intelligence section, and advising the fires officer on sensor-to-target pairing and targeting cycle management. You write three to four Sgt FitReps per cycle, build the sensor support training schedule against NAVMC 3500.44 collective tasks, brief the battalion or regimental fires officer on sensor coverage and targeting integration at every planning event, and coordinate with the MEF fires section and joint targeting assets on sensor employment at echelon. You are the senior enlisted who understands both the sensor side and the fires side — the radar, the UAS, the SIGINT, and how all of it feeds through the D3A cycle into fire missions. The SSgt-to-GySgt board is FitRep-driven — one weak cycle changes the timeline more than most SSgts realize.

• 01Manage the sensor-to-shooter architecture across a battalion frontage — sensor allocation, coverage analysis, sensor-to-target pairing, and real-time reallocation when sensors go offline or priorities change — and brief the architecture to the fires officer at every planning event.
• 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 target acquisition platoon, the UAS section, the intelligence section, and the battalion FDC on sensor employment, ISR coverage, intelligence correlation, and targeting cycle management — the sensor integration chief who works in isolation produces a worse targeting picture than the one who integrates.
• 04Advise the fires officer on sensor capabilities and limitations at the targeting meeting — honest assessments of what the sensors can detect, what they cannot, and what the coverage gaps mean for the fire support plan.
• 05Mentor two to three Sgts into Career Course graduates and SSgt-board-ready candidates with both sensor employment depth and targeting process understanding.
• 06Brief the battalion commander and the fires officer honestly on sensor readiness, coverage gaps, targeting integration risks, and the second-order effects of operations tempo on sensor support crew proficiency.

• —FM 3-09 — Field Artillery Operations and Fire Support (you operate at the battalion and regimental targeting level; understanding target engagement authority, the targeting cycle, and sensor-to-shooter integration is your primary responsibility).
• —JP 3-60 — Joint Targeting (D3A and F3EAD at the joint level; you apply and brief these methodologies to the fires officer and the targeting board).
• —NAVMC 3500.44 — Marine Corps Artillery T&R Manual (sensor support collective standards you build training against).
• —MCWP 3-15 — Marine Corps Fire Support (the fire support coordination framework for the MAGTF; you brief the targeting integration within this framework).
• —MCO 1610.7 — Performance Evaluation System (FitRep policy for the Sgts 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 battalion expects the senior targeting SNCO to be a senior instructor.
• —Sensor coverage of the high-payoff target list at or above the battalion commander's requirement through the full operations cycle.
• —Targeting products delivered to the fires officer at every targeting meeting — on time, with honest gap assessments, grounded in sensor capabilities.
• —FitRep relative value above battalion average — one weak cycle on the SSgt-to-GySgt board moves the timeline by years.

• —Delivering a sensor coverage assessment to the fires officer that overpromises what the sensors can do. The fires officer who plans a fires program based on sensor coverage that does not exist discovers the problem when the high-payoff target fires undetected — and the SNCO who briefed the coverage owns the gap.
• —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 the sensor support sections to operate independently without integrating their products. Two sensor sections reporting the same detection as separate targets produces duplicate fire missions — the SNCO who did not integrate the products wasted ammunition and confused the targeting picture.
• —Treating the intelligence section as a competitor rather than a partner. Sensor data without intelligence context is half the picture — the targeting SNCO who does not coordinate with the S2 produces a targeting product the fires officer cannot fully trust.
• —Hiding a sensor readiness gap from the fires officer before the exercise. The fires officer finds out from the battalion commander when the targeting cycle produces a gap that should have been briefed during planning.

The good SSgt 0847 is the targeting SNCO the fires officer walks out of the operations order brief and trusts that the sensor coverage is allocated, the targeting products are current, and the sensor-to-shooter chain will deliver detections fast enough to generate fire missions before the targets displace. His section chiefs are Career Course-ready, and the battalion S2 knows his name because the intelligence-sensor integration actually works.

You are the battalion targeting chief or the senior fires integration SNCO at the regimental or MEF fires section. The sensor-to-shooter chain that connects every detection to every fire mission runs on the architecture you built, the Marines you trained, and the targeting process you manage.

You serve as the battalion targeting chief or the senior fires integration SNCO at the regiment or MEF fires section — the billet that owns the targeting cycle, the sensor-to-shooter architecture, and the integration of sensor data into the fires program at echelon. You write three to five SSgt FitReps per cycle that feed the GySgt board, brief the battalion or regimental commander on targeting integration status and sensor-to-shooter effectiveness at every BUB, and manage the targeting training program across the formation. You coordinate with the MEF fires section, the division targeting cell, and joint targeting assets on sensor employment and targeting cycle management at echelon. You mentor two or three SSgts toward Career Course graduation and GySgt-board readiness, set the standard for targeting product quality across the formation, and carry the honest read on which Sgts are sensor-employment specialists and which ones are fires-integration generalists who should move into broader fire support billets.

• 01Brief the battalion or regimental commander on targeting integration status, sensor-to-shooter effectiveness, coverage gaps, and known targeting risks at every BUB — before the commander 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 targeting training program across the formation — sensor integration exercises, targeting cycle drills, cross-functional targeting meetings, and sensor-to-shooter timelines — and deliver proficiency assessments to the 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 targeting SME the MMPB needs at the MEF fires section.
• 05Coordinate with the MEF fires section, the division targeting cell, and joint targeting assets on sensor employment at echelon — the targeting chief who coordinates upward produces a better picture than the one who only looks at his own sensors.
• 06Brief the battalion SgtMaj and the commander honestly on sensor support morale, targeting crew proficiency, retention, and the second-order effects of operations tempo on targeting effectiveness.

• —FM 3-09 — Field Artillery Operations and Fire Support (you operate at the regimental and MEF targeting level; this is the doctrinal spine of every targeting integration brief you give).
• —JP 3-60 — Joint Targeting (the joint targeting doctrine you apply and teach; D3A and F3EAD at echelon).
• —NAVMC 3500.44 — Marine Corps Artillery T&R Manual (battalion-level targeting standards; the commander evaluates the targeting 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 targeting integration within this framework).
• —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 battalion or regimental level.
• —Targeting cycle effectiveness — detections converted to fire missions within the commander's timeline through the full operations cycle.
• —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 formation watches the targeting chief's scores.

• —Allowing the sensor-to-shooter timeline to become a planning artifact rather than a trained standard. The targeting cycle that looks good on the briefing slide but has never been tested under time pressure produces a sensor-to-shooter timeline the formation cannot actually execute.
• —Confusing being tight with the commander with being aligned with the commander. The battalion needs you to push back on a targeting plan that overpromises sensor coverage — in his office, with the door closed.
• —Carrying a sensor-side vs. fires-side preference into the targeting chief billet. The targeting chief who over-invests in one side produces a targeting cycle where the other side disconnects — and the fire missions suffer.
• —Allowing the targeting training program to stagnate because "we did this last quarter." Sensor capabilities evolve, threats evolve, and the targeting cycle that worked during the last exercise may not work for the next one.
• —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 0847 is the targeting chief the battalion commander can brief a fires plan to on Monday and trust that the sensors are allocated, the targeting products are current, the sensor-to-shooter timeline is trained, and the targeting cycle will deliver fire missions before the high-payoff targets displace. His SSgts are Career Course-ready, his Marines re-enlist because of the technical credibility and the targeting 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 sensor-to-shooter integration. Every detection that became a fire mission, every targeting cycle that delivered on time, and every sensor support Marine who produced a targeting product the fires officer could trust traces back to a standard you set and a Marine you developed.

As 1stSgt you run the target acquisition or fires support battery — 80 to 150 Marines, the battery office, the section chiefs and platoon sergeants, the training calendar, and the boundary between what the battery commander needs and what the battery can deliver in targeting integration. As MSgt you are the senior targeting SME at the battalion, regimental, or MEF fires section — targeting integration chief, sensor employment advisor to the fires officer, or the senior enlisted who shapes the next generation of 0847 GySgts and targeting chiefs. As SgtMaj you advise the battalion or regimental commander on every enlisted decision in the fires and targeting community and you set the standard for how sensor support Marines are developed, employed, and retained across an entire echelon. As MGySgt you are the occupational pinnacle of the sensor support field — the Marine the HQMC fires community calls when the 0847 MOS structure, the targeting T&R program, or the sensor integration doctrine needs an enlisted practitioner's voice. You write fewer FitReps but the ones you write determine the next targeting chief, 1stSgt, and MSgt slates.

• 01Run a 1stSgt's call that handles accountability, sick call, discipline, family readiness, training calendar, and sensor readiness status in 30 minutes flat — without the battery gunny running to fill the gaps.
• 02Build a battery quarterly training schedule with the battery commander and the operations officer that builds targeting proficiency and sensor integration depth without burning the crews out on an operations tempo that produces analysis 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 targeting SME the MMPB needs at the MEF fires section or HQMC fires community.
• 04Walk the targeting section during a live-fire evaluation or major exercise and identify the sensor integration failures, the targeting product gaps, and the sensor-to-shooter timeline breakdowns before the evaluators do.
• 05Brief the battalion or regimental commander and the BSgtMaj on battery morale, targeting crew proficiency, sensor readiness, and the second-order effects of targeting 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 sensor support Marines; the targeting Marine who understands maneuver is the one who understands why sensor-to-shooter timelines are 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 targeting integration revision cycle starts).
• —JP 3-60 — Joint Targeting (the joint targeting doctrine you have applied across your career; you teach D3A and F3EAD to the next generation).
• —MCO 1610.7 — Performance Evaluation System (you are the rater or reviewing officer on the FitReps that determine the next 0847 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).

• —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.
• —Targeting cycle effectiveness and sensor-to-shooter integration 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 targeting culture that treats the sensor-to-shooter timeline as an aspirational goal rather than a trained standard. The targeting cycle that breaks down under pressure because the battery gunny never enforced the timeline produces missed fire missions — 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 sensor support Marines are still watching how you carry it.

The good 1stSgt / SgtMaj 0847 is the senior Marine every sensor support Marine in the formation knows by face and reputation. He is the reason the re-enlistment line forms after a hard deployment where the targeting cycle never stopped and every sensor detection mattered. 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 targeting integration T&R program needs rewriting — and the targeting chiefs across the MEF quote him at sensor integration training without realizing they are doing it.
