Fire Support Marine

You are the fire support Marine. You live with the infantry, eat with the infantry, hump with the infantry, and when the platoon commander needs steel on an enemy position, you are the Marine who calls for fire. The grunts do not care about your MOS — they care whether the rounds land where you said they would.

You arrive at your infantry battalion or artillery regiment from the Basic Fire Support course at Fort Sill — alongside Army 13F students — and the fire support team chief drops you into the FIST embedded with a rifle company or platoon. You do not live with the artillery battery. You live with the infantry, and you carry everything they carry plus the radios, the laser rangefinder, and the call-for-fire knowledge that makes you the link between the maneuver element and the fires that support it. In garrison you train on call-for-fire procedures, laser rangefinder operation, fire support coordination, radio procedures, and the infantry tactics you will use alongside the grunts because you move with them and you fight with them. In the field you observe targets, determine grid coordinates using the LLDR (Lightweight Laser Designator Rangefinder) or map-compass-binocular methods, transmit calls for fire to the FDC over the fire support net, adjust fires onto the target, and report battle damage assessment. You also maintain situational awareness of friendly positions, no-fire areas, and restricted fire areas — because a call for fire that lands on friendlies is the worst failure in fire support.

• 01Transmit a call for fire in the standard CFF format — observer identification, warning order, target location (grid, shift, polar), target description, method of engagement, method of fire and control — to the FDC over the fire support net without a cheat sheet.
• 02Operate the LLDR (Lightweight Laser Designator Rangefinder) to determine target grid coordinates — range, azimuth, vertical angle, computed grid — and verify the grid against the map before transmitting the call for fire.
• 03Adjust fires onto the target — direction, distance, and vertical adjustments — using the standard adjustment technique (bracket-and-halving or successive-adjustment) until rounds are on target or fire for effect is authorized.
• 04Operate fire support radios — AN/PRC-152A, AN/PRC-163 — on the fire support net, load CEOI without a printed cheat sheet, and maintain communications with the FDC during movement and operations.
• 05Zero and qualify the M27 IAR or M4 to the Annual Rifle Training (ART) standard — Expert is the floor; you are living with the infantry and you fight as an infantryman when you are not calling for fire.
• 06Run a TCCC casualty assessment — MARCH-PAWS — and apply a CAT tourniquet under fire, because you are with the forward element and the corpsman may be two fire teams away.

• —MCWP 3-16 — Fire Support Coordination in the Ground Combat Element (the primary USMC fire support coordination doctrine — call-for-fire procedures, fire support planning, coordination measures, and the role of the fire support Marine in the MAGTF).
• —JP 3-09 — Joint Fire Support (the joint doctrine for fire support that governs how fire support Marines integrate with joint fires — CAS, naval gunfire, joint mortars — beyond organic artillery).
• —FM 3-09 — Field Artillery Operations and Fire Support (the doctrinal framework the FDC processes your calls for fire against).
• —NAVMC 3500.44 — Marine Corps Artillery Training and Readiness Manual (the individual and collective tasks for 08-series Marines, including fire support).
• —MCO 6100.13 — Marine Corps Physical Fitness, Body Composition, and Military Appearance (your PFT/CFT standard — you hump with the infantry, and the grunts notice if you cannot keep up).

• —1st-Class PFT and CFT — you live with the infantry and you carry your gear plus the LLDR, the radios, and the batteries. If you cannot hump, you cannot do the job.
• —Annual Rifle Qualification: Expert is the floor. You fight alongside the infantry before you call for fire.
• —Process a call for fire from target observation through fire-for-effect within the battery's time standard — the platoon commander who called for fire support does not have time to wait for you to look up the format.
• —MCMAP Gray Belt before LCpl; Green Belt before you sit a Corporals Course board.
• —Operate the LLDR and determine a target grid that is accurate to the system's precision — the FDC fires what you give them, and an inaccurate grid means rounds on the wrong position.

• —Transmitting a call for fire with an incorrect target grid. The FDC fires what you tell them to fire — a transposed digit or a miscalculated polar-to-grid conversion moves the round hundreds of meters, and the round does not know it was supposed to land somewhere else.
• —Failing to check the target grid against the current friendly positions and fire support coordination measures before transmitting the call for fire. A call for fire that lands inside a no-fire area or on a friendly position is the worst failure in fire support, and "I forgot to check" does not survive the investigation.
• —Losing communications with the FDC during a fire mission because you did not maintain the radio or load the correct CEOI. The infantry platoon that needed fire support and did not get it because you could not reach the FDC remembers.
• —Falling out of a hump or movement because your kit is not squared away or your fitness is not at the infantry standard. The fire support Marine who cannot keep up with the platoon cannot observe the target area, cannot call for fire, and cannot do the job — the grunts will request someone else.
• —Posting any information about fire support plans, target lists, fire support coordination measures, or FDC frequencies on social media. Fire support data is a high-value intelligence indicator for any adversary.

The good junior fire support Marine is invisible the right way inside the infantry platoon — kit squared, radio working, LLDR charged, call-for-fire format memorized, mouth shut during the patrol and ready to talk when the platoon commander says "I need fires on that position." By month nine the FIST chief is letting him call adjust missions without coaching on the radio; by the LCpl evaluation cycle the infantry company knows his name and the fire support team chief has put him on the Corporals Course slate.

You are an NCO embedded with the infantry. In this Corps the chevron means it the first time you pin it — Cpl in the fire support team means you are the Marine the FIST chief trusts to call for fire independently, adjust rounds onto a target while under fire, and keep the infantry platoon commander from having to think about the fire support plan while he is running the fight.

You are a FIST (Fire Support Team) member — embedded with an infantry company or platoon alongside the FIST chief — and you are the Marine who calls for fire, adjusts fires, conducts target observation, and maintains fire support coordination with the FDC and the maneuver element. You operate independently when the FIST chief splits the team, calling fires for one platoon while the chief supports another. You are pursuing or have completed the JFO (Joint Fires Observer) qualification — the credential that authorizes you to provide targeting data for CAS (Close Air Support) and naval gunfire in addition to artillery. You write proficiency and conduct marks for any junior fire support Marines assigned to you, you train them on call-for-fire procedures and LLDR operation, and you are the Marine the infantry platoon commander calls "my FO" even though that title has not been your official job title since your grandfather's Corps. You are also watching your Sgt timeline — Corporals Course is gated, the cutting score moves, and the fire support Marine who earns JFO qualification and understands joint fires integration is the one the battery commander promotes.

• 01Call for fire independently — target observation, grid determination (LLDR or polar), CFF transmission, adjustment, fire for effect, BDA — without the FIST chief on the radio coaching you through the format.
• 02Employ the DAGR (Defense Advanced GPS Receiver) and the LLDR together to determine target coordinates with sufficient accuracy for precision munitions — the precision-guided munition does not correct for your sloppy grid.
• 03Build and brief a fire support plan for the infantry platoon's scheme of maneuver — targets, triggers, priority of fires, fire support coordination measures, no-fire areas — in a format the platoon commander can use during the OPORD.
• 04Operate as a JFO (Joint Fires Observer) or JFO candidate — provide targeting data for CAS terminal attack control, talk to the JTAC on the CAS stack frequency, and provide Type 2/3 control terminal guidance under the JTAC's authority.
• 05Operate fire support radios — AN/PRC-152A, AN/PRC-163 — on both the fire support net and the CAS net, and maintain communications during movement, contact, and displacement.
• 06Train junior fire support Marines on CFF procedures, LLDR operation, and fire support coordination until they can call adjust missions without supervision.

• —MCWP 3-16 — Fire Support Coordination in the Ground Combat Element (the primary USMC fire support reference — call-for-fire, fire support planning, FIST employment, and coordination measures).
• —JP 3-09 — Joint Fire Support (joint fire support doctrine — CAS procedures, naval gunfire, JFO qualification, and how fire support Marines integrate with joint fires).
• —JP 3-09.3 — Close Air Support (CAS procedures, Type 1/2/3 control, and the JFO's role in providing targeting data to the JTAC).
• —NAVMC 3500.44 — Marine Corps Artillery T&R Manual (FIST member collective tasks at the Cpl level).
• —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 0861 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 FIST chief notes on the FitRep going to the Sgt board.
• —1st-Class PFT and CFT — you hump with the infantry and they do not wait for the fire support Marine who cannot keep up.
• —JFO (Joint Fires Observer) qualification completed or in progress — this is the career-defining credential at the Cpl-Sgt level, and the fire support Marine who does not pursue it is leaving the most consequential certification in the MOS on the table.
• —Composite score tracked monthly in TFRS; pull the current cutting score for 0861 to Sgt before asking the FIST chief where you stand.

• —Calling for fire without verifying the target grid against the current friendly positions. The call for fire that lands on friendlies because you did not check the grid against the maneuver element's position destroys the trust the infantry had in you — and it may destroy the Marines.
• —Failing to pursue JFO qualification when the school slot is available. JFO is the credential that separates a fire support Marine who can only call artillery from one who can integrate joint fires — CAS, naval gunfire, and the full spectrum. The Cpl who delays JFO is delaying his own career.
• —Losing the LLDR or the DAGR during a movement. These are sensitive items that cost more than you will make in a year — and the fire support team that loses its ranging and targeting equipment cannot do the job. The investigation starts with you.
• —Trying to adjust fires by memory instead of by the standard adjustment procedure. The adjustment technique exists because fire support Marines under stress make predictable errors when they freelance — bracket-and-halving works; guessing does not.
• —Going around the FIST chief to the infantry platoon commander with a fire support recommendation before briefing the chief. The FIST chief has context you do not have — the coordination measure that changed, the CAS stack that is overhead, the adjacent unit that moved — and the Cpl who bypasses him risks a fire support error the chief would have caught.

The good Cpl 0861 is the fire support Marine the FIST chief sends to the second platoon when the team splits and trusts to call fires independently — correct grid, correct CFF format, correct adjustment technique, correct fire support coordination measure check — without a radio call asking for help. His junior Marines are training on CFF procedures during garrison weeks, he is JFO-qualified or within one board cycle of it, and the infantry platoon commander he is embedded with asks the company commander to keep him for the next deployment.

The fire support team is yours. Two to four fire support Marines, the infantry company you are embedded with, and the company commander is counting on you to integrate every available fire support asset — artillery, mortars, CAS, naval gunfire — into his scheme of maneuver without killing his own Marines.

You run the FIST (Fire Support Team) — two to four fire support Marines embedded with an infantry company — and you are responsible for their training, their proficiency, and the accuracy of every fire support action the team executes. You build the company fire support plan with the company commander, attend the company OPORD, brief the fire support annex, and coordinate fires with the battalion fire support coordinator (FSC). You are JFO-qualified and you call for fire, adjust fires, and provide targeting data for CAS under the JTAC's authority. You split the team when two platoons need fire support simultaneously, and you are the Marine who manages the fire support coordination measures for the company — the no-fire areas, the restricted fire areas, and the boundaries that prevent fratricide. You write FitReps on your Cpls under MCO 1610.7, mentor them toward JFO qualification and Sergeants Course readiness, and you are the fire support subject matter expert the company commander leans on for every fires decision. The honest reality: you are the Marine Corps equivalent of the Army's 13F FIST chief, and the infantry company's fires capability is only as good as your planning, your execution, and your judgment.

• 01Build a company fire support plan that integrates artillery, mortars, CAS, and naval gunfire into the company commander's scheme of maneuver — targets, triggers, priority of fires, fire support coordination measures, on-call missions — and brief it during the company OPORD.
• 02Call for fire and adjust fires independently as the FIST chief while simultaneously managing the company's fire support coordination — the FIST chief who cannot call fires while tracking coordination measures is the FIST chief who will either miss targets or hit friendlies.
• 03Write FitReps on your fire support Marines per cycle under MCO 1610.7 — observed behavior, action-result-impact, defensible relative value — that the reporting senior can defend.
• 04Operate as a qualified JFO — provide Type 2/3 CAS terminal guidance under the JTAC's authority, talk to the CAS stack, provide targeting data for precision and area weapons, and conduct joint fires coordination with the JTAC and the FSC.
• 05Coordinate with the battalion FSC on fire support coordination measures, target deconfliction, and fires priority — the FIST chief who operates in isolation from the battalion fire support plan produces dangerous fires.
• 06Mentor your fire support Marines into JFO-qualified, Sergeants Course-ready candidates who can split from the team and call fires independently.

• —MCWP 3-16 — Fire Support Coordination in the Ground Combat Element (the primary USMC fire support reference — FIST employment, fire support planning, coordination measures, and the FIST chief's role in the company fight).
• —JP 3-09 — Joint Fire Support (joint fire support doctrine — JFO procedures, naval gunfire, CAS integration, and joint fires coordination).
• —JP 3-09.3 — Close Air Support (CAS procedures, Type 1/2/3 control, and the JFO's role — you are the JFO at the company level).
• —NAVMC 3500.44 — Marine Corps Artillery T&R Manual (FIST chief collective tasks; the FSC evaluates your team against this).
• —MCO 1610.7 — Performance Evaluation System (you write FitReps for your fire support Marines now).
• —MCO 1400.32 — Marine Corps Promotion Manual (SSgt board mechanics, composite scores, 0861 MOS roadmap).

• —Sergeants Course graduate — required and gated.
• —JFO (Joint Fires Observer) qualified — this is the non-negotiable credential for the FIST chief at E-5 and above. A FIST chief without JFO qualification cannot integrate joint fires, and the company commander deserves a FIST chief who can.
• —Brown Belt MCMAP minimum; Black Belt is what the battery gunny notes going to the SSgt board.
• —1st-Class PFT and CFT — you hump with the infantry company and the grunts watch whether the FIST chief can carry his load plus the radios and the LLDR.
• —Composite score tracked monthly; pull the current MARADMIN cutting score for 0861 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.
• —Building a fire support plan that looks good on the overlay but has not been coordinated with the battalion FSC. The company fire support plan that conflicts with the battalion fire support plan produces fire support coordination measure violations that put friendly forces at risk.
• —Calling for fire on a target without checking the grid against the current friendly positions and the current coordination measures. The FIST chief who fires on friendlies or into a no-fire area has committed the worst failure in fire support — and "the measures changed and I didn't know" means you were not tracking the FSC net.
• —Failing to split the team when two platoons need fire support simultaneously. The FIST chief who keeps both fire support Marines with him leaves one platoon without fires — the company commander will notice and the Marines on that platoon will remember.
• —Doing the fire support coordination yourself instead of teaching the Cpl to do it. The team will fail when you go to Sergeants Course, and you will be the reason.

The good Sgt 0861 is the FIST chief the infantry company commander trusts to integrate every fires asset the battalion has — artillery, mortars, CAS, naval gunfire — into the company's scheme of maneuver without killing his own Marines. His fire support Marines are JFO-qualified or tracking toward it, his fire support plan survives contact because he coordinated it with the FSC before the OPORD, and the company commander asks the battalion to keep him for the next deployment because the fires were on time, on target, and safe.

You are the battalion fire support chief or the senior FIST chief. Whether you are managing the fire support teams across the battalion or advising the battalion fire support coordinator on fires integration, the battalion's ability to integrate fires into maneuver without fratricide runs through what you plan, what you train, and what you enforce.

You serve as the battalion fire support chief — the senior enlisted fire support Marine at the battalion level — managing three to five FISTs embedded with the rifle companies and advising the battalion fire support coordinator (FSC) on fires integration, coordination measures, and fire support planning. You write three to four Sgt FitReps per cycle on your FIST chiefs, build the fire support training schedule against NAVMC 3500.44 collective tasks, and brief the battalion commander on fire support readiness and fires integration at every planning event. You coordinate with the artillery battery FDC on target deconfliction, with the JTAC on CAS integration, with the mortar platoon on close fires, and with adjacent unit FSCs on boundary coordination. You manage the JFO qualification pipeline for the battalion's fire support Marines — the FIST chief without JFO is a FIST chief who cannot integrate joint fires, and you are the Marine who ensures every FIST chief gets the school slot. The SSgt-to-GySgt board is FitRep-driven — one weak cycle changes the timeline more than most SSgts realize.

• 01Build a battalion fire support plan that integrates artillery, mortars, CAS, and naval gunfire into the battalion commander's scheme of maneuver — fire support coordination measures, target lists, triggers, priority of fires, and JFO employment — and brief it during the battalion OPORD.
• 02Write three to four Sgt FitReps per cycle under MCO 1610.7 that the reporting senior can defend at the battalion FitRep review.
• 03Manage the JFO qualification pipeline for the battalion's fire support Marines — school slots, qualification boards, recertification timelines — and deliver the JFO readiness report to the FSC.
• 04Coordinate with the artillery battery FDC, the JTAC, the mortar platoon, and adjacent unit FSCs on target deconfliction, coordination measures, and boundary management — the battalion fire support chief who operates in isolation produces dangerous fires plans.
• 05Mentor two to three FIST chiefs into Career Course graduates and SSgt-board-ready candidates with JFO qualification and fire support planning depth.
• 06Brief the battalion commander and the FSC honestly on fire support readiness, FIST proficiency, JFO qualification status, and the second-order effects of operations tempo on fire support Marine proficiency.

• —MCWP 3-16 — Fire Support Coordination in the Ground Combat Element (the primary USMC fire support reference at the battalion level — fire support planning, coordination measures, FIST employment, and the FSC's role).
• —JP 3-09 — Joint Fire Support (joint fire support doctrine — JFO procedures, naval gunfire, CAS integration, and joint fires coordination at echelon).
• —JP 3-09.3 — Close Air Support (CAS procedures at the battalion level — Type 1/2/3 control, JTAC/JFO relationships, and CAS integration into the battalion fight).
• —NAVMC 3500.44 — Marine Corps Artillery T&R Manual (battalion fire support collective standards you build training against).
• —MCO 1610.7 — Performance Evaluation System (FitRep policy for the FIST 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 battalion expects the senior fire support SNCO to be a senior instructor.
• —All battalion FIST chiefs JFO-qualified or on a tracked timeline to qualification — the fire support chief who cannot report JFO status to the FSC has not done his job.
• —Battalion fire support plan integrated and coordinated with adjacent units and the regiment FSC before every major exercise.
• —FitRep relative value above battalion average — one weak cycle on the SSgt-to-GySgt board moves the timeline by years.

• —Building a battalion fire support plan without coordinating with the regiment FSC on boundary coordination measures. The battalion fire support plan that conflicts with the adjacent battalion's plan produces fratricide at the boundary — and the fire support chief who did not coordinate owns the gap.
• —Writing a FitRep as a wish list instead of an evaluation. The reporting senior who defends an inflated FIST chief at the battalion FitRep board remembers the SSgt who wrote it.
• —Allowing the JFO qualification pipeline to stagnate because "school slots are limited." The fire support chief who does not fight for JFO school slots is accepting a battalion fire support capability that cannot integrate joint fires — and the battalion commander does not know until the CAS stack is overhead and nobody can talk to it.
• —Treating the FIST chiefs as interchangeable. Each FIST chief has different strengths — some are better at CAS integration, some at danger-close fires, some at naval gunfire — the fire support chief who does not know his bench cannot make the right assignment.
• —Hiding a fire support readiness gap from the FSC before the exercise. The FSC finds out from the battalion commander when the company that needed fires could not get them because the FIST was not prepared.

The good SSgt 0861 is the battalion fire support chief the FSC walks out of the operations order brief and trusts that every FIST is manned, JFO-qualified, embedded with the right company, and ready to integrate fires into the maneuver scheme without coordination measure violations. His FIST chiefs are Career Course-ready with joint fires depth, and the regiment FSC knows his name before the battalion commander introduces him.

You are the regimental fire support chief or the senior fire support SNCO at the regimental or MEF level. Every fire support plan that integrates fires into maneuver, every FIST that calls for fire without killing friendlies, and every JFO-qualified Marine who provides CAS terminal guidance traces back to the standard you set and the Marines you developed.

You serve as the regimental fire support chief — the senior enlisted fire support Marine at the regiment — or the senior fire support SNCO at the MEF fires section, managing the fire support architecture across the regiment's battalions and advising the regimental fire support coordinator on fires integration, coordination measures, and fire support planning at echelon. You write three to five SSgt FitReps per cycle that feed the GySgt board, brief the regimental commander on fire support readiness and fires integration at every BUB, and manage the JFO qualification program across the regiment. You coordinate with the division fires section, the wing DASC (Direct Air Support Center) on CAS allocation, the naval gunfire liaison on ship-to-shore fires, and adjacent regiment FSCs on boundary coordination. You mentor two or three SSgts toward Career Course graduation and GySgt-board readiness, set the fire support training standard across the regiment, and carry the honest read on which FIST chiefs are ready for battalion fire support chief billets.

• 01Brief the regimental commander on fire support readiness, JFO qualification status, fires integration quality, and known fire support risks at every BUB — before the commander has to ask.
• 02Write three to five SSgt FitReps per cycle under MCO 1610.7 that the regimental FitRep board can defend — clean attribute rationale, defensible relative value.
• 03Manage the JFO qualification program across the regiment — school slots, qualification boards, recertification timelines, and the JFO readiness posture the regiment needs for the next deployment or exercise.
• 04Coordinate with the division fires section, the wing DASC, the naval gunfire liaison, and adjacent regiment FSCs on fires integration at echelon — the regimental fire support chief who only looks down at his battalions and not up and across produces a fire support architecture with dangerous gaps.
• 05Mentor 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 support SME the MMPB needs at the MEF fires section.
• 06Brief the regimental SgtMaj and the commander honestly on fire support morale, FIST proficiency, retention, and the second-order effects of operations tempo on fire support Marine readiness.

• —MCWP 3-16 — Fire Support Coordination in the Ground Combat Element (the primary USMC fire support reference at the regimental level; you own the fire support standard across the regiment).
• —JP 3-09 — Joint Fire Support (joint fire support doctrine at echelon; you coordinate with joint fires assets and you teach your FIST chiefs to operate within the joint fires architecture).
• —JP 3-09.3 — Close Air Support (CAS integration at the regimental level; you coordinate with the wing DASC on CAS allocation and employment).
• —NAVMC 3500.44 — Marine Corps Artillery T&R Manual (regimental-level fire support standards; the regimental commander evaluates the fire support proficiency against this).
• —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 regimental level.
• —Regimental JFO qualification rate at or above the MEF standard — the regimental fire support chief who cannot put a JFO-qualified FIST chief in every rifle company is accepting a fires integration gap the regimental commander should know about.
• —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 fire support formation watches the senior SNCO's scores.

• —Allowing the fire support training standard to vary across battalions without regimental-level standardization. The battalion whose fire support training is weak produces a FIST team that makes coordination measure errors at the boundary with the battalion whose training is strong — and the fratricide happens at the seam the regimental fire support chief should have strengthened.
• —Confusing being tight with the regimental commander with being aligned with the regimental commander. The regiment needs you to push back on a fires plan that overpromises what the FISTs can deliver — in his office, with the door closed.
• —Carrying a battalion-preference bias into the regimental fire support chief billet. The regimental fire support chief who invests disproportionately in the battalion he came from produces a regiment where the other battalions know it and the fire support quality reflects it.
• —Allowing the CAS integration skills to atrophy because CAS is "the JTAC's job." The fire support chief who cannot coordinate with the DASC, brief CAS allocation, and manage JFO employment at the regimental level is missing half the fires available to the regiment.
• —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 0861 is the regimental fire support chief the FSC can brief a regiment-level fires plan to on Monday and trust that every battalion has JFO-qualified FIST chiefs, the coordination measures are coordinated across boundaries, and the fire support architecture will deliver fires without fratricide. His SSgts are Career Course-ready with joint fires depth, his Marines re-enlist because of the training standard and the credibility of the fire support program, and the MEF fires SNCO is already mentioning his name for the MSgt or 1stSgt slate before the board convenes.

You are the standard-bearer for fire support. Every FIST that integrated fires without killing friendlies, every JFO who provided CAS terminal guidance under fire, and every fire support plan that survived contact traces back to a standard you set and a Marine you developed.

As 1stSgt you run the fire support battery or the fires headquarters element — 80 to 150 Marines, the battery office, the FIST chiefs and fire support section leaders, the training calendar, and the boundary between what the battery commander needs and what the formation can deliver in fire support integration. As MSgt you are the senior fire support SME at the regiment, division, or MEF fires section — fire support integration chief, JFO program manager, or the senior enlisted who shapes the next generation of 0861 GySgts and fire support chiefs. As SgtMaj you advise the battalion or regimental commander on every enlisted decision in the fire support community and you set the standard for how fire support Marines are developed, employed, and retained across an entire echelon. As MGySgt you are the occupational pinnacle of the fire support field — the Marine the HQMC fires community calls when the 0861 MOS structure, the fire support T&R program, or the JFO qualification doctrine needs an enlisted practitioner's voice. You write fewer FitReps but the ones you write determine the next fire support chief, 1stSgt, and MSgt slates.

• 01Run a 1stSgt's call that handles accountability, sick call, discipline, family readiness, training calendar, and fire support readiness status in 30 minutes flat — without the battery gunny running to fill the gaps.
• 02Build a fire support battery or headquarters quarterly training schedule with the commander and the operations officer that builds FIST proficiency, JFO qualification rates, and joint fires integration depth without burning the fire support Marines out on a tempo that produces coordination 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 support SME the MMPB needs at the MEF fires section or HQMC fires community.
• 04Walk the fire support teams during a live-fire evaluation or major exercise and identify the CFF errors, the coordination measure failures, and the JFO employment gaps before the evaluators do.
• 05Brief the battalion or regimental commander and the BSgtMaj on fire support morale, FIST proficiency, JFO qualification posture, and the second-order effects of fire support 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 support Marines; the FIST chief who understands maneuver is the one who understands why fire support coordination is not negotiable).
• —MCWP 3-16 — Fire Support Coordination in the Ground Combat Element (the primary USMC fire support reference you have operated within your entire career; you are the practitioner the doctrine team calls when the revision cycle starts).
• —JP 3-09 — Joint Fire Support; JP 3-09.3 — Close Air Support (the joint doctrine you applied and taught across your career).
• —MCO 1610.7 — Performance Evaluation System (you are the rater or reviewing officer on the FitReps that determine the next 0861 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.
• —Formation JFO qualification rate and fire support proficiency at or above the MEF 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 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 fire support training culture that accepts coordination measure violations as "training opportunities" instead of near-misses. A coordination measure violation during training is a fratricide during operations — the 1stSgt who allows the culture accepts the risk.
• —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 support Marines are still watching how you carry it.

The good 1stSgt / SgtMaj 0861 is the senior Marine every fire 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 fire support plan held together under fire and every call for fire landed where it was supposed to. The commander trusts him with the worst news at 0200; the Marines trust him to fight for the JFO school slots, 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 support T&R program or the JFO qualification doctrine needs rewriting — and the FIST chiefs across the MEF quote him at fire support training without realizing they are doing it.
