0861 Fire Support Marine

You are moving with a rifle company through broken terrain when the lead element makes contact. The commander looks at you. You are the only fires expert in that formation, and the whole battery is waiting on a call for fire. You locate the target, transmit the grid, and talk the rounds onto it. That is the 0861 Fire Support Marine. You are the link between what the maneuver unit sees and what the artillery can do about it.

If you want the artillery field but want your daily identity to be about observation, coordination, and operating close to the fight, this is the role that delivers it.

Job Role and Responsibilities

The 0861 Fire Support Marine provides forward observation, liaison, and fire-support coordination to Marine ground maneuver units. You identify and locate targets, process calls for fire, coordinate the employment of artillery, mortars, naval gunfire, and close air support, and advise ground commanders on available fire-support assets and how to use them effectively in their battle plan.

Daily Tasks

In garrison, you work within the battery headquarters or a fire-support coordination element. Time goes into training on call-for-fire procedures, map and terrain analysis, digital targeting systems, and fire-support planning. You rehearse target grids, run through clearance-of-fires procedures, and train on the radio protocols that connect you to fire-direction centers, supported unit headquarters, and adjacent fires elements.

In the field, you move with the supported maneuver unit. That might be a rifle company, a weapons company, or a battalion headquarters. You carry your own radio, your laser range-finding optics, and a communications plan that keeps you tied into the fires net regardless of what terrain you cross. At observation posts, you record target reference points, build range cards, and identify avenues of enemy approach that would put threats inside your battery’s effective range. When contact happens, you have seconds to get a call for fire out. The faster and more accurately you transmit, the better the chance that the first adjustment brings rounds onto the target.

For Marines who earn Joint Terminal Attack Controller (JTAC) certification, the mission expands to include controlling close air support. JTAC-qualified 0861 Marines direct fighter aircraft and attack helicopters onto targets, a responsibility that requires a separate certification and continuous currency maintenance.

Specific Roles

Mission Contribution

An artillery battery with no observer is a powerful weapon with no eyes. The 0861 Marine is those eyes. Positioned with a rifle company, you give the maneuver commander a direct line to every indirect fire asset available: artillery batteries, mortar sections, naval surface fire support, and close air support if you are JTAC-qualified. Without you, the commander has to rely on visual sighting and improvised calls. With you, the unit brings precision indirect fire onto targets that small arms cannot reach, at ranges that change the tactical equation.

The quality of that connection depends entirely on your skill. An inaccurate grid or a slow transmission means rounds arrive late or land in the wrong place. Precise, rapid calls for fire mean the supported unit gets the fires it needs in the window it has.

Technology and Equipment

Fire support Marines carry and operate a range of targeting and communication tools:

• Vector 21 and similar laser range-finding binoculars for precise target location
• Digital Automated Communications Terminal (DACT) and AFATDS-connected tablets for digital call-for-fire submission
• Encrypted tactical radios for voice communication with fire-support networks
• Handheld laser designators and target location systems in JTAC-qualified billets
• Digital mapping systems for fire-support plan development and target reference point management

Salary and Benefits

Financial Benefits

Pay is determined by rank and years of service. You enter at E-1 and advance through the enlisted pay scale as you build proficiency and take on leadership roles.

Source: DFAS 2026 pay tables. Figures reflect the 2026 pay raise.

Additional pay and allowances include:

• Basic Allowance for Subsistence (BAS): $476.95 per month for enlisted Marines (2026 rate)
• Basic Allowance for Housing (BAH): varies by duty station, pay grade, and dependency status
• Special duty or imminent danger pay during eligible deployments

Additional Benefits

Active-duty Marines receive TRICARE Prime at no cost, covering medical, dental, vision, mental health, and prescriptions. Dependents enrolled under your plan pay no enrollment fee.

Education benefits include Tuition Assistance (up to $4,500 per year) while on active duty and the Post-9/11 GI Bill after separation. The GI Bill covers full in-state tuition at public schools and up to $29,920.95 per academic year at private institutions (2025-2026 cap), plus a monthly housing allowance and up to $1,000 per year in book stipends.

Retirement under the Blended Retirement System (BRS) provides a pension at 20 years equal to 40 percent of your average highest 36 months of basic pay, plus government-matched Thrift Savings Plan contributions beginning in year three of service.

Work-Life Balance

Marines earn 30 days of paid leave per year, accruing 2.5 days per month with a 60-day maximum carryover. Marines attached to infantry and maneuver units follow those units’ tempo. That can be more demanding than battery garrison schedules during training exercises and pre-deployment workups. 0861 Marines operate where the supported unit operates, and that unit is not always on a predictable garrison schedule.

Fire support Marines attached to infantry units often experience more field time per year than battery-internal 0811 or 0844 Marines. Infantry battalions train continuously and in the field frequently. As the fires representative embedded with that unit, you train with them. That means more time away from home station between deployments, not less. JTAC-qualified Marines may have additional currency training requirements that add further time commitments.

Plan leave carefully and use the windows between major training events. The 60-day carryover cap is a real issue for Marines with high operational tempo. Unused leave above the cap is forfeited at the fiscal year boundary, so tracking your balance and coordinating leave requests with your chain of command matters.

Qualifications and Eligibility

Basic Qualifications

The 0861 MOS requires communication skill, spatial awareness, and coordination ability in addition to the standard combat-arms baseline. ASVAB requirements reflect the communication-heavy and technically demanding nature of the role.

The GT 100 minimum reflects the coordination, communications, and analytical demands of fire-support work. Marines who want this MOS should take the ASVAB seriously and specifically prepare for the verbal and arithmetic components that drive the GT composite. The PiCAT is an option for first-time testers before going to MEPS.

Application Process

Enlisting into 0861 follows the standard Marine path:

1. Contact a Marine Corps recruiter and express interest in the 08 Field Artillery field and fire-support track
2. Take the ASVAB or PiCAT to confirm GT 100 or higher
3. Complete the MEPS physical examination
4. Select an available 0861 contract if scores and Marine Corps needs align
5. Ship to Boot Camp at MCRD Parris Island or MCRD San Diego

Selection Criteria and Competitiveness

0861 contracts are fewer than basic cannoneer slots. The GT 100 threshold and the fire-support coordination emphasis mean Marines who score higher and demonstrate communication skills are stronger candidates. Prior team leadership experience, athletics, or emergency response work can help frame your candidacy, but the ASVAB threshold is the practical gate.

Upon Accession into Service

You enter at E-1 (Private). The standard enlistment obligation is four years active duty. Confirm your specific contract length with your recruiter before signing.

Work Environment

Setting and Schedule

0861 Marines work in two distinct environments. In garrison, they work in battery headquarters or fire-support coordination elements on planning, training, and communications drills. In the field, they detach from the battery and attach to maneuver units, operating from observation posts, at combat outposts, or within infantry formation command posts.

The field assignment tempo follows the supported unit. During exercises and operations, you move when they move, stop when they stop, and stay on the radio when they are in contact. Night operations are regular. Infantry units do not pause at dark, and fire-support Marines attached to them do not either.

Leadership and Communication

A single 0861 Marine advising a rifle company commander during a training exercise represents the fires community to that commander. There is no team around you to share the visibility. Communication quality, target priority judgment, and procedural confidence are on display from early in the career. That individual accountability suits Marines who are comfortable operating independently while still working within a larger fires coordination system.

Performance feedback follows Marine Corps standards: proficiency and conduct marks for E-4 and below, counseling and FITREPs for E-5 and above.

Team Dynamics and Autonomy

The role involves both tight teamwork (coordinating across multiple fire-support nets simultaneously) and significant individual initiative (being the sole fires expert within a maneuver unit). More experienced 0861 Marines receive greater autonomy in planning and mission execution because the supported unit’s commander is relying on their independent judgment. Junior Marines build that credibility through demonstrated proficiency in calls for fire and fire-support planning.

Job Satisfaction and Retention

Marines who want variety, tactical complexity, and close integration with maneuver forces consistently report this MOS as engaging. You see more of the combined-arms environment than any battery-internal role does. Retention among experienced 0861 Marines is generally positive because the skill set builds value over time and the work remains challenging as you advance through the ranks.

Training and Skill Development

Initial Training

The fire-support track at Fort Sill focuses on the complete coordination cycle: target observation, call-for-fire transmission, adjustment of fire, and end-of-mission reporting. You also learn how to advise maneuver commanders on available fires, read terrain for observation post siting, and coordinate between multiple fire-support systems that are firing simultaneously. The course is communication-intensive by design because the job is communication-intensive by requirement.

Advanced Training

Experienced 0861 Marines have access to several development paths:

• Joint Terminal Attack Controller (JTAC) certification for qualified Marines, enabling them to control close air support and significantly expanding their career value
• Advanced Fire Support Course for senior NCOs moving into fire-support team lead roles
• Joint Fire Support Executive Course (JFSEC) for Marines assigned to joint headquarters billets
• Reconnaissance observation training alongside scout and recon communities
• Marine Corps Institute (MCI) distance-education courses in leadership, communications, and operations at no cost to active-duty Marines
• Sergeant’s Course and SNCO professional military education for career advancement

JTAC certification is one of the most valuable qualifications available in the 08 field. It requires dedicated training, a formal certification process, and continuous currency requirements. The qualification significantly expands both your value to the force and your post-service career options. If JTAC is something you want, be direct about that with your chain of command early in your career.

Career Progression and Advancement

Career Path

Role Flexibility and Transfers

0861 Marines can apply for lateral moves into 0844 Fire Control or 0842 Radar through the LATMOVE program if they want to shift within the 08 field. The skills built in fire-support coordination also provide a foundation for moves into intelligence, reconnaissance, and joint fires communities with the right additional training and command endorsement. The key window for requesting a LATMOVE is at reenlistment, before the next contract is locked. Moves are not guaranteed but become more achievable with a strong FITREP record and a command recommendation.

Performance Evaluation

E-4 and below receive proficiency and conduct marks from their chain of command. These marks contribute to the composite score used in promotion consideration. E-5 and above receive FITREPs that are evaluated by promotion boards at competitive grades.

Fire support Marines are assessed on proficiency in call-for-fire procedures, JTAC currency where applicable, effectiveness as a fires advisor to supported unit commanders, and quality of leadership within the fire support team. Marines who demonstrate both technical fires proficiency and strong peer relationships with supported infantry leadership are the most competitive candidates for promotion at the NCO and SNCO levels. The fire support role is visible to commanders outside the artillery community, and strong performance with supported units generates FITREP comments that stand out during promotion board review.

Physical Demands and Medical Evaluations

Physical Requirements

0861 Marines attached to maneuver units move with those units on foot. That means extended foot patrols, movement to observation posts on difficult terrain, and sustained operations in all weather conditions carrying your own equipment. The physical demands are closer to infantry standards than to battery garrison work. Marines in this MOS should maintain fitness at the high end of the Marine Corps standard, because attached assignments are physically demanding and your credibility with the infantry unit you are supporting depends partly on your ability to keep up.

Marines must pass the PFT and CFT twice per year.

PFT and CFT Standards (2026)

Verify current standards at marines.mil before making any service decisions.

Medical Evaluations

Marines complete a full physical at MEPS before accession. Periodic preventive medical exams continue throughout service. 0861 Marines attached to maneuver units share that unit’s occupational exposure profile, which includes noise from artillery and close air support fires. Hearing protection is required at observation posts and during fire missions. JTAC-qualified Marines may face additional medical screening requirements for specific joint assignments.

Deployment and Duty Stations

Deployment Details

0861 Marines deploy as part of artillery units and fire-support coordination elements. They can serve with Marine Expeditionary Units, infantry battalions, and regimental combat teams. MEU deployments typically last seven to nine months. Fire-support Marines often deploy attached to infantry battalions, which means following that battalion’s schedule and operational tempo rather than the battery’s.

JTAC-qualified 0861 Marines are in high demand for joint and special operations environments. Selected Marines with the certification can find themselves attached to task forces where fire-support coordination skills are the primary requirement.

Location Flexibility

Active-duty 0861 Marines serve at artillery and infantry units at the following installations:

ANGLICO (Air Naval Gunfire Liaison Company) units at Camp Lejeune and Camp Pendleton also use 0861 Marines in specialized liaison roles with other service branches and allied forces. JTAC-qualified fire support Marines are particularly sought after for ANGLICO billets.

Family Life and Quality of Living

The duty-station quality-of-life picture for 0861 Marines tracks with the larger artillery field. Camp Pendleton offers San Diego access and a strong military community. Camp Lejeune sits near Jacksonville, North Carolina, a city shaped heavily by military presence. Twentynine Palms is the most austere posting, with a sparse civilian economy and desert climate. Families at any of these locations benefit from MCCS programs, the unit FRO network, and the Military OneSource system.

Risk, Safety, and Legal Considerations

Job Hazards

0861 Marines positioned with forward maneuver elements operate in the same risk environment as the infantry units around them. Observation post duty, foot patrols in contested terrain, and coordination during active fire missions all carry physical risk. The closer you are to the forward edge of the battle, the more exposure you share with the units you support.

Errors in call-for-fire procedures carry serious consequences. A wrong grid, a wrong description of effects, or a failed clearance-of-fires check can put rounds on the wrong position. Fire support Marines are trained to prevent these errors through a systematic call-for-fire sequence, and that training is reinforced at every exercise because the consequences of skipping steps are irreversible.

Safety Protocols

Clearance-of-fires procedures are the central safety mechanism in fire-support work. Every call for fire includes a mandatory verification sequence that confirms rounds will not land on friendly positions, civilian infrastructure, or restricted areas. These procedures are trained to standard at the schoolhouse and enforced at every live-fire exercise. Senior fire-support leaders supervise all missions during training to build habits that hold under operational stress.

JTAC-qualified Marines working with aircraft have additional safety requirements tied to airspace deconfliction and weapons release authority.

Security and Legal Requirements

Fire support Marines typically need Secret clearance eligibility to access fire-support planning systems and classified radio nets. JTAC-qualified Marines working in joint assignments may require higher clearance levels for specific tasks. Discuss your background thoroughly with your recruiter early in the process if clearance eligibility is a concern.

UCMJ obligations apply throughout service.

Impact on Family and Personal Life

Family Considerations

0861 Marines attached to infantry units follow those units’ operational tempo, which is typically more demanding than battery garrison schedules. Deployments are regular, and the frequency of field training with maneuver units means time away from home is higher than in many support roles. Over a four-year enlistment, a significant portion of that time is away from home station.

The Marine Corps supports families through Military OneSource, MCFTB, and MCCS programs at every major installation. The Family Readiness Officer at each unit is the primary support contact for families before and during deployments.

Relocation

Active-duty 0861 Marines move every two to three years on PCS orders. Relocation support includes BAH, household goods transportation assistance, and advance pay options. Preferred assignments can be requested but are not guaranteed.

Marine Corps Reserve

Component Availability

The 0861 MOS is available in the Marine Corps Reserve within artillery units and fire-support coordination elements of Marine Forces Reserve.

Drill Schedule and Training Commitment

Standard reserve commitment is one weekend per month plus two weeks per year. Fire support Marines need regular practice on call-for-fire procedures and coordination with fires elements to maintain proficiency. Reserve units with live-fire training opportunities and working relationships with nearby maneuver units provide better training value for 0861 Marines than units that only run classroom training. Before choosing a unit, ask about the frequency of live-fire exercises and whether the unit conducts field training with supported maneuver elements.

Part-Time Pay

An E-4 Corporal with two years of service earns $3,303.00 per month on active duty. Reserve drill pay is 1/30th of monthly basic pay per drill period. A standard drill weekend of four periods produces approximately $440 before taxes.

Benefits Differences

Deployment and Mobilization

Reserve 0861 Marines are subject to mobilization under Title 10 orders. JTAC-qualified reserve Marines are in high demand during mobilizations, which can affect how frequently those individuals are called up. During mobilization, pay and benefits match active-duty standards.

Civilian Career Integration

Fire-support coordination experience translates into civilian roles in emergency management, interagency coordination, and operations management. JTAC-certified Marines have direct credentials for defense contractor positions supporting air-ground integration programs. USERRA protects your civilian job rights during mobilizations.

Post-Service Opportunities

Transition to Civilian Life

0861 builds communication, coordination, target analysis, and high-stakes decision-making skills. These qualities transfer into civilian emergency management, law enforcement, defense contracting, and intelligence roles. The Transition Readiness Program (TRP) helps you frame fire-support experience for civilian employers who may not know what a call for fire is.

The Post-9/11 GI Bill is often the most important financial resource in this transition. Marines who combine fire-support background with a degree in criminal justice, emergency management, or a technical field position themselves for strong civilian outcomes. JTAC certification and a Secret clearance extend those options significantly into defense and government roles.

Civilian Career Prospects

Salary data from the U.S. Bureau of Labor Statistics Occupational Outlook Handbook.

JTAC certification and a Secret clearance are competitive qualifications for defense contractor, intelligence support, and joint operations roles, even without a degree. A degree through the GI Bill raises the ceiling on what those qualifications can command in compensation.

Is This a Good Job for You? The Right (and Wrong) Fit

Ideal Candidate Profile

You are a strong candidate for 0861 if you want the artillery field but are drawn to communication, coordination, and working alongside other units rather than staying battery-internal. The right person for this MOS is a clear and calm communicator, performs accurately when multiple fires nets are active simultaneously, and understands that the job is to serve the supported unit’s needs. Physical fitness matters here at a level closer to infantry than to battery garrison work.

Potential Challenges

0861 is the wrong choice if you want the gun line or the FDC’s computational identity. If you want the physical artillery role, the 0811 Field Artillery Cannoneer is the right fit. If you want the technical computation side, the 0844 Field Artillery Fire Control Marine is the match.

Teaching infantry leaders how fires work is part of the job. You will regularly work alongside units that do not fully understand the fire-support process. That requires patience and the confidence to explain your expertise without being dismissive. Marines who struggle with that kind of peer advisory role tend to find the attached environment frustrating.

Career and Lifestyle Alignment

0861 is a strong long-term path for Marines who want broad fires experience, a path to JTAC certification, and post-service credentials that translate into defense, law enforcement, and emergency management careers. You see more of the combined-arms environment than any battery-internal role does, and that breadth has value both in service and after.
