1390 Expeditionary Fuels Officer

The 1390 Expeditionary Fuels Officer is the Marine Corps technical authority on bulk fuel operations and expeditionary fuel systems. You solve fuel support problems that generalist officers and senior SNCOs cannot address alone. This is a warrant officer path built for experienced enlisted Marines who want to stay embedded in the expeditionary fuels community while stepping into officer-level technical leadership. If you have spent years managing bulk fuel receipt, storage, transfer, and dispensing in austere conditions, this role turns that hands-on expertise into a career-long technical specialty. If you need to improve your GT score before applying, structured ASVAB preparation can help you reach the required threshold.

Job Role and Responsibilities

A 1390 Expeditionary Fuels Officer manages bulk fuel operations, fuel support planning, and fuel system readiness for Marine logistics units. You oversee fuel system operations, coordinate fuel distribution, manage fuel quality and environmental compliance, and advise commanders on fuel requirements and expeditionary fuel infrastructure. This role exists to preserve deep technical expertise in bulk fuel systems that the Corps cannot afford to lose to the generalist officer rotation cycle.

The 1390 operates at the intersection of fuel operations, logistics planning, and technical advisory work. At the CWO2 and CWO3 levels, you are on the ground supervising fuel system operations, managing fuel bladders and storage tanks, coordinating fuel distribution convoys, and ensuring that fuel quality and environmental standards are maintained. At CWO4 and above, you transition to program management at the regiment, MEF, or force level, where you set fuels policy, develop training standards, and coordinate with Defense Logistics Agency and joint fuels authorities.

This role differs from the enlisted 1391 Expeditionary Fuels Technician who operates individual fuel systems. The 1390 manages the entire fuels program. It also differs from the commissioned logistics officer who plans broader supply operations. The 1390 is the technical advisor who ensures the fuel systems those operations depend on are operational, compliant, and capable of supporting the MAGTF.

MOS Designations

Mission Contribution

The 1390 Expeditionary Fuels Officer is essential to Marine Air-Ground Task Force sustainment. Every Marine vehicle, aircraft, and generator requires fuel. Without a technical expert who understands fuel system capabilities, storage requirements, environmental compliance, and distribution logistics, commanders cannot accurately plan operations or assess fuel support readiness. The 1390 bridges the gap between enlisted fuels technicians who execute the work and commissioned officers who plan logistics missions.

Technology, Equipment, and Systems

The 1390 manages expeditionary fuel systems including collapsible fuel storage tanks, fuel bladders, fuel distribution pumps, hose and coupling systems, fuel quality testing equipment, and environmental containment systems. Diagnostic tools include fuel quality analysis kits, electronic fuel inventory management systems, and environmental compliance tracking software. The 1390 also works with Defense Logistics Agency Energy and joint fuels authorities on fuel supply chain management and expeditionary fuel infrastructure planning.

Salary and Benefits

Warrant officer base pay is determined by years of service and pay grade. Marine warrant officers enter from the enlisted ranks with significant time in service, so their pay reflects total years of service rather than time as a warrant officer.

Pay figures are from the 2026 DFAS warrant officer basic pay tables. Actual compensation is significantly higher when allowances are included.

Additional Benefits

Warrant officers receive Basic Allowance for Housing at officer rates, which varies by duty location and dependency status. Basic Allowance for Subsistence for officers is $328.48 per month in 2026. Healthcare is provided through TRICARE Prime with no enrollment fee, deductible, or copay for the service member. Family members are enrolled under the sponsor TRICARE Prime plan with no enrollment fee and zero copay for in-network care.

The Blended Retirement System applies to warrant officers. After 20 years of total service, retirement pay equals 40 percent of the high-36 average basic pay. The Thrift Savings Plan includes automatic 1 percent government contributions plus matching up to 4 percent of basic pay when the member contributes 5 percent. Continuation pay is available between 8 and 12 years of service.

The Post-9/11 GI Bill provides up to 36 months of education benefits with full in-state tuition at public schools or up to $29,920.95 per year at private institutions. Warrant officers with six years of service can transfer unused GI Bill benefits to dependents with a four-year additional service obligation.

Work-Life Balance

Warrant officers earn 2.5 days of leave per month, totaling 30 days per year, with up to 60 days carryover. In garrison, the schedule follows a standard workday with occasional evening and weekend requirements for fuel system inspections and environmental compliance reviews. During field exercises and deployments, the tempo increases significantly with continuous fuel operations, convoy coordination, and 24-hour fuel support requirements.

The warrant officer lifestyle offers more technical focus and less staff grind than commissioned officer billets. You are not rotating through generalist staff assignments. You stay in your technical lane, which means more predictable career progression and deeper subject matter expertise. Compared to senior SNCOs, warrant officers have more autonomy in technical decision-making and less direct personnel administration burden.

Qualifications and Eligibility

Marine Corps warrant officers are selected exclusively from the enlisted ranks. There is no civilian-to-warrant or street-to-seat path in the Marine Corps. The 1390 Expeditionary Fuels Officer path is designed for Marines who have already built substantial credibility in the expeditionary fuels community.

Appointment Path

The primary feeder MOS for 1390 is 1391 Expeditionary Fuels Technician. The baseline requirement is typically Staff Sergeant (E-6) or above, though specific requirements vary by MARADMIN and MOS proponent guidance. Candidates must demonstrate hands-on competence with expeditionary fuel systems, bulk fuel operations, and environmental compliance procedures.

Selection Board Process

Warrant officer selection is announced annually via MARADMIN. The board cycle typically opens in the fall with package deadlines in the winter or early spring. Marines should begin preparing at least six months before the deadline.

A competitive application package includes command endorsements through the chain of command to the first general officer, current and historical fitness reports, evidence of PME completion, civilian education transcripts, awards and decorations, and a personal statement addressing expeditionary fuels experience and warrant officer motivation. For 1390, endorsements typically come from the combat logistics regiment commanding officer and the MEF logistics director.

The board evaluates candidates on technical expertise in expeditionary fuels, leadership potential, physical readiness, and career trajectory. Demonstrated competence in bulk fuel operations and environmental compliance is the primary differentiator. Marines who have served as fuels chiefs, fuel system supervisors, or fuels training NCOs should document those assignments clearly.

Test Requirements

Candidates must meet the aptitude standards established by the MOS proponent. The General Technical (GT) line score is the primary metric for warrant officer candidates. A competitive GT score demonstrates the cognitive ability required for technical analysis, fuel systems troubleshooting, and advisory-level communication. Marines seeking to improve their GT score should study the verbal expression, arithmetic reasoning, and mathematics knowledge subtests of the ASVAB. Resources like the ASVAB study guide can help improve line scores before board submission.

Upon Appointment

Newly selected warrant officers enter at W-1 (Warrant Officer 1). The Minimum Service Requirement upon appointment is typically four years of active duty service as a warrant officer. W-1 holders receive a warrant of appointment. Upon promotion to CW2, they receive a commission.

Work Environment

Setting and Schedule

The 1390 Expeditionary Fuels Officer works at fuel farms, bulk fuel storage facilities, field fuel points, and staff offices. In garrison, the schedule follows a standard workday with fuel system inspections, environmental compliance reviews, and administrative requirements. During field exercises, the 1390 operates from forward fuel sites where fuel distribution and quality control are constant demands. Deployments place the 1390 in austere environments where expeditionary fuel system establishment is critical to mission success.

Position in the Unit

The 1390 serves as a technical advisor within combat logistics regiments, MEF-level logistics staffs, and Marine Forces logistics commands. Warrant officers are not in the traditional command chain. Instead, they advise commanders on fuel capability, distribution logistics, and environmental compliance. The relationship with the commander is advisory and technical. The 1390 works closely with senior SNCOs who manage day-to-day fuel operations, and with commissioned logistics officers who plan supply missions.

The warrant officer-SNCO-officer dynamic works because each role has a distinct lane. The SNCO runs the fuel system floor. The 1390 manages the fuels program and advises on technical policy. The commissioned logistics officer plans the supply mission and commands the unit. This structure prevents overlap and ensures fuels expertise is preserved at the staff level.

Technical vs. Staff Roles

At W-1 and CW2, the 1390 spends most of the time on hands-on technical work. You are inspecting fuel systems, reviewing quality control records, training fuels personnel, and troubleshooting fuel distribution issues. At CW3, the role shifts toward section leadership and program management. You manage fuels programs independently and mentor junior warrant officers and senior enlisted Marines. At CW4 and CW5, the role becomes predominantly staff advisory. You set policy, develop training standards, and coordinate with Defense Logistics Agency and joint fuels authorities.

Job Satisfaction and Retention

Warrant officers in the 1390 community report high job satisfaction due to sustained technical focus and reduced bureaucracy compared to commissioned officer career paths. The role allows experienced fuels Marines to stay in their field instead of rotating into unrelated staff assignments. Retention is strong because the Corps values deep fuels expertise and provides clear progression from technical specialist to senior technical advisor. Common reasons for staying include technical depth, advisory authority, and the ability to shape fuels policy at higher echelons.

Training and Skill Development

Warrant Officer Basic Course

All newly appointed Marine warrant officers attend the Warrant Officer Basic Course at Marine Corps Base Quantico, Virginia. WOBC covers MOS-specific technical training, leadership development, and Marine Corps organization at the officer level.

WOBC differs from enlisted MOS school in its officer-level focus on leadership, advisory skills, and staff processes. It differs from The Basic School for commissioned officers in its technical depth and single-track specialization model.

Warrant Officer Career Course

The Warrant Officer Career Course is typically attended as a CW2 or CW3. It covers advanced technical skills in expeditionary fuels management, logistics leadership, and staff advisory techniques. The course is conducted at the appropriate Marine Corps training command and runs for several weeks.

Warrant Officer Intermediate Level Education

Intermediate level education is attended as a CW3 or CW4. It is available in resident, non-resident, and blended formats. The curriculum broadens the warrant officer beyond the technical lane and develops joint and MAGTF-level advisory skills. This education level prepares the 1390 for regiment and MEF-level staff billets.

Warrant Officer Senior Service Education

Senior service education is attended as a senior CW4 or CW5. It covers strategic-level technical advisory skills, force-level planning, and senior leadership competencies. This education prepares the 1390 for CWO5-level billets as the senior technical advisor for fuels at the force or Marine Forces level.

Additional Schools and Training

The Marine Corps funds additional training through COOL (Credentialing Opportunities On-Line) for 1390 warrant officers. Relevant credentials include petroleum logistics management certifications, environmental compliance certifications, hazardous materials management credentials, and supply chain management certifications. Tuition Assistance provides up to $4,500 per year for civilian degree completion programs. The 1390 may also attend specialized courses in fuel quality testing, environmental remediation, and joint fuels logistics.

Career Progression and Advancement

Rank Progression

Promotion System

Promotion from W-1 to W-2 is time-based after completion of WOBC. Promotions to CW3, CW4, and CW5 are board-selected through the Marine Corps warrant officer promotion board system. Marine warrant officers receive fitness reports using the same reporting system as commissioned officers. Competitive fitness reports, completed PME, civilian education, and documented technical achievements drive board selection.

Promotion to CW5 is highly competitive due to the limited number of senior warrant billets. A CW5 1390 serves as the senior technical advisor for fuels at the force or Marine Forces level. The role involves force-wide fuels policy, fuel system oversight, and strategic-level technical guidance that shapes how the entire Corps manages its bulk fuel operations and expeditionary fuel infrastructure.

Building a Competitive Record

A competitive 1390 record includes strong fitness reports that document fuels program management results, completed PME at each career stage, civilian education in logistics management or environmental science, deployment experience in fuels support roles, and evidence of technical innovation or process improvement in fuel operations. Marines should seek assignments that demonstrate increasing scope of fuels program responsibility, from company-level fuels officer to regiment-level technical lead to MEF-level advisor.

Physical Demands and Medical Evaluations

Warrant officers must meet the same physical fitness standards as all Marines. The 1390 does not require a flight physical or specialized medical evaluation beyond standard Marine Corps requirements. However, the job involves working around bulk fuel systems, conducting field inspections in austere environments, and managing fuel distribution operations, which demands baseline physical readiness.

PFT and CFT Standards

The following standards apply to the youngest age group (17-20). All Marines must maintain a minimum passing score on both the PFT and CFT.

Deployment and Duty Stations

Deployment Details

Expeditionary fuels warrant officers deploy with their units as part of Marine expeditionary units or larger Marine Air-Ground Task Forces. The standard MEU deployment runs approximately seven months, during which the 1390 manages bulk fuel operations in expeditionary conditions.

Expeditionary fuels work requires establishing and operating fuel systems in austere environments. You are managing fuel bladders, storage tanks, and dispensing equipment that support ground vehicles, aircraft, and generators. The fuel is heavy, the environmental risks are real, and the expectation is that the warrant officer can maintain fuel quality and safety standards even when conditions are challenging.

Deployments to CENTCOM, INDOPACOM, and EUCOM are the most common. In these theaters, 1390s coordinate with joint fuels partners and manage fuel supply chains that support combat operations, training exercises, and theater security cooperation activities.

Duty Station Options

Primary duty stations for 1390 Expeditionary Fuels Officers include Camp Pendleton, California; Camp Lejeune, North Carolina; Marine Corps Base Quantico, Virginia; and Marine Corps Logistics Base Albany, Georgia. Overseas assignments include Camp Kinser in Okinawa, Japan, and Marine Corps Base Hawaii.

Warrant officer duty station assignments are determined through the Marine Corps Manpower Management Office Allocation process, which balances unit vacancies, individual preferences, and career development requirements. The 1390 community has duty station options concentrated at installations with significant logistics missions. The technical nature of the role can provide more stability at a given installation compared to commissioned officers who rotate more frequently.

Risk, Safety, and Legal Considerations

Job Hazards

The 1390 Expeditionary Fuels Officer faces hazards associated with bulk fuel operations, including fire and explosion risks, hazardous vapor exposure, fuel spill contamination, and heavy equipment operation near fuel systems. Field environments add risks from unimproved terrain, limited lighting, and austere fuel handling conditions. While the 1390 is not in the direct fire line like infantry Marines, deployment to combat zones exposes the role to indirect fire, improvised explosive devices targeting fuel infrastructure, and other combat hazards.

Safety Protocols

The 1390 employs Operational Risk Management frameworks for all fuel operations and environmental compliance activities. Pre-operation fuel system inspections, spill prevention protocols, and hazardous materials handling procedures are standard practice. The 1390 conducts safety inspections of fuel systems and ensures that fuels personnel maintain current qualifications and training certifications. During deployments, the 1390 integrates force protection measures into fuel operations planning.

Authority and Responsibility

The 1390 holds technical authority over fuel operations and environmental compliance within the assigned unit. This includes the authority to halt fuel operations that are unsafe, to direct corrective environmental actions, and to recommend fuel system disposition decisions. The 1390 is subject to the Uniform Code of Military Justice as a commissioned officer (CW2 and above) or warrant holder (W-1). Technical failures or safety violations in this MOS can result in environmental contamination, mission degradation, or personnel injury, with consequences ranging from administrative action to UCMJ proceedings depending on severity and negligence.

Impact on Family and Personal Life

Family Considerations

The 1390 Expeditionary Fuels Officer career involves the same PCS moves and deployment separations as other Marine officer careers. However, warrant officers typically experience fewer PCS moves than commissioned officers because they remain in their technical specialty rather than rotating through diverse staff and command billets. This provides more stability for families in terms of school continuity, spouse employment, and community connections.

Marine Corps Community Services, Military OneSource, and Marine Corps Family Team Building provide support programs for families during deployments and relocations. Spouse employment assistance programs help military spouses find portable careers or remote work opportunities.

Dual-Military and Family Planning

The Marine Corps handles dual-military warrant officer couples through the Joint Domicile program, which attempts to co-locate married service members at the same duty station. Warrant officer couples face the same challenges as any dual-military family, including coordinated deployment schedules and childcare during field exercises.

Warrant officers generally have more predictable assignment cycles than commissioned officers, which helps with family planning. Deployments follow the unit MEU rotation schedule, which provides advance notice for family preparation. Extended field exercises are typically announced months in advance through the unit training calendar.

Marine Corps Reserve

Component Availability

The 1390 Expeditionary Fuels Officer MOS is available in the Marine Corps Reserve. Reserve fuels units are organized within Marine Forces Reserve and support the same MAGTF structure as active component units. Reserve 1390 billets exist in combat logistics regiments and logistics support companies within the Selected Marine Corps Reserve.

Appointment Paths

Reserve warrant officer appointment for 1390 follows the same MARADMIN board process as active duty. Enlisted Reserve Marines in feeder MOS (1391) can apply through their reserve unit chain of command. Active-duty warrant officers who transfer to the Marine Corps Reserve retain their warrant grade and continue their career progression within the reserve component.

Drill and Training Commitment

The standard reserve commitment is one weekend per month (drill) plus two weeks per year (Annual Training). For 1390 Reserve warrant officers, additional training days may be required for fuel system certifications, environmental compliance qualifications, and readiness inspections. The technical nature of the role demands currency with fuel systems and environmental procedures, which may require additional inactive duty training periods beyond the standard schedule.

Part-Time Pay

A Reserve W-2 or CW3 earns base pay proportional to drill periods completed. Each drill period equals one-thirtieth of the monthly base pay rate. A typical drill weekend includes four drill periods.

Annual Training pay equals 14 days of active-duty base pay plus full BAH and BAS for the training period.

Benefits Differences

Reserve warrant officers are eligible for Tricare Reserve Select, which requires monthly premiums significantly lower than civilian health insurance. As of 2026, individual premiums are approximately $50 per month and family premiums approximately $230 per month. Coverage is comparable to TRICARE Prime with network provider requirements.

Federal Tuition Assistance is available for reserve members at up to $4,500 per year. GI Bill eligibility accrues based on active-duty service periods, including Annual Training and mobilizations. The reserve retirement system is points-based. A good year requires 50 or more retirement points. Retirement pay begins at age 60 (reducible by 90 days for each 90 consecutive days of qualifying active duty) and is calculated at 2.5 percent per equivalent year of service times the high-36 average base pay.

Career Progression

Reserve warrant officers can progress to CW4 and CW5, though the number of senior reserve billets is limited. Promotion timing may differ from active duty due to fewer available positions and the part-time nature of reserve service. Reserve warrant officers are eligible for career-level courses, intermediate education, and senior service education through blended and non-resident formats.

Deployment and Mobilization

Reserve 1390 warrant officers may be mobilized for combat deployments, active-duty operational support tours, or emergency response missions. Mobilization length typically ranges from 6 to 12 months. Reserve fuels units have been mobilized for contingency operations, humanitarian assistance missions, and homeland defense support.

Civilian Career Integration

The 1390 Reserve warrant officer role pairs well with civilian careers in petroleum logistics, fuel distribution, and environmental compliance. Many reserve 1390s work for oil companies, fuel distribution firms, or environmental consulting agencies during the week and bring that civilian expertise to their reserve drill weekends. Reserve service enhances civilian career prospects by demonstrating sustained technical leadership and the ability to manage complex fuel operations under demanding conditions.

USERRA protections guarantee reemployment rights for reserve members returning from military duty. Employer Support of the Guard and Reserve provides resources for both service members and civilian employers.

Active vs. Reserve Comparison

Post-Service Opportunities

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

Ideal Candidate Profile

The 1390 Expeditionary Fuels Officer is a strong fit for Marines who have spent years in the expeditionary fuels community and want to deepen their technical expertise rather than broaden into generalist roles. You should have a genuine interest in bulk fuel systems, environmental compliance, and technical problem-solving. Successful 1390s are detail-oriented, comfortable advising senior leaders, and able to communicate complex technical information clearly to non-technical audiences.

Potential Challenges

The warrant officer path is not ideal for Marines who want command authority. Warrant officers are technical advisors, not unit commanders. If you want to lead troops in a traditional command role, the commissioned officer path through MECEP or LDO programs may be a better fit. Promotion to CW5 is highly competitive with very limited billets. The small peer community means fewer lateral career options if you want to change specialties mid-career.

Career and Lifestyle Alignment

The 1390 aligns well with long-term career goals for Marines who want to serve 20 to 30 years and reach the senior technical advisor level. It also works for Marines who plan to transition after their initial warrant obligation, since the civilian career transfer value is strong in petroleum logistics and environmental compliance. Compared to staying enlisted as a senior SNCO, the warrant path offers more autonomy and advisory authority. Compared to commissioning, it offers deeper technical focus and less staff rotation.
