3002 Ground Supply Officer

The 3002 Ground Supply Officer leads one of the clearest sustainment communities in the Marine Corps. This is an unrestricted officer MOS accessible through standard commissioning sources. The role centers on accountability, supply systems, and readiness. Supply officers manage the material support that keeps Marines equipped and operational. If you want officer responsibility built around logistics and supply chain management rather than maneuver or maintenance, the 3002 is a strong fit.

Job Role and Responsibilities

A 3002 Ground Supply Officer leads Marines and manages the supply picture that keeps units equipped, accountable, and ready to operate. The officer handles storage, issue, inventory visibility, requisition processing, supply planning, and support integration across the unit. The role requires strong attention to detail, resource management skill, and the ability to advise commanders on supply readiness and material availability.

The supply chain and material management occupational field centers on the 3002 MOS. This is the primary designation for officers leading supply operations across the operating forces.

Ground supply officers contribute directly to MAGTF readiness by ensuring that units have the material support needed to execute their mission. The supply enterprise covers inventory management, requisition processing, supply accountability, warehouse operations, and material distribution. Without functional supply support, the ground combat element cannot sustain operations. The 3002 officer ensures that the supply system works and that the commander can trust the supply data.

The equipment and systems a 3002 officer manages include the unit’s entire property book, controlled inventory items, sensitive items, and equipment requiring special handling or security. Officers employ supply management information systems such as GCSS-MC to track inventory, process requisitions, and report supply readiness to higher headquarters. The officer works closely with the S-1 on personnel logistics, the S-3 on operational planning, and the S-4 on broader logistics coordination. The enlisted 30XX community provides the technical backbone of supply operations, while the 3002 officer leads those Marines and integrates their work into the commander’s operational plan.

Salary and Benefits

Marine officers are paid on the standard DoD officer pay scale. Base pay for early-career ground supply officers runs as follows.

Ground supply officers do not receive aviation or diving special pays. Hazardous duty pay may apply depending on specific assignments. Accession and retention bonuses vary by year and Marine Corps manning priorities.

Officers receive full TRICARE Prime health coverage with no enrollment fee, no deductible, and no copays for medical, dental, vision, mental health, prescriptions, or hospitalization. Family members are also covered under TRICARE Prime with zero out-of-pocket costs when using in-network providers. Officers receive a monthly Basic Allowance for Subsistence of $328.48 and Basic Allowance for Housing based on their duty location, pay grade, and dependency status.

All officers participate in the Blended Retirement System. After 20 years of service, officers receive a pension equal to 40 percent of their high-36 average basic pay. The government contributes 1 percent of basic pay automatically to the Thrift Savings Plan after 60 days of service, vesting at 2 years. Officers who contribute 5 percent of their own pay receive up to 4 percent in government matching contributions.

Officers earn 30 days of leave per year, accruing 2.5 days per month with a maximum carryover of 60 days. Garrison schedules follow a predictable routine with morning physical training and standard work hours. Field exercises and deployment periods reduce personal time significantly. Supply officers face heavy preparation demands during pre-deployment workup cycles, including equipment resets, supply prepositioning, and transportation coordination.

Qualifications and Eligibility

There are six main paths to a Marine officer commission. Each route has its own academic and age requirements.

PLC is the most common undergraduate route for students who want a Marine commission while staying in school. OCC is a 10-week program at Quantico for college seniors and graduates. NROTC Marine Option combines academic study with officer development on campus. The Naval Academy provides a four-year service academy path. MECEP and ECP allow enlisted Marines to earn degrees and commission as officers. OCC and MECEP candidates take the ASVAB as part of their screening process.

All candidates must be U.S. citizens. Supply is an unrestricted officer field accessible through any commissioning source. Current public sources do not show a separate aviation-style test or unusual gate for 3002. Candidates must meet standard Marine officer commissioning requirements including citizenship, age, degree, and physical fitness standards.

MOS assignment happens at The Basic School. All newly commissioned Marine officers attend TBS regardless of their intended field. Class standing at TBS, personal preference, and the needs of the Marine Corps determine who receives a supply assignment. Supply is moderately competitive. Officers who want 3002 need solid TBS performance and a clear preference ranking.

New officers enter at O-1, Second Lieutenant. The standard minimum service requirement is 8 years of active duty. Officers who do not complete their full service obligation may face financial penalties or other administrative consequences.

Work Environment

A 3002 officer’s daily setting shifts between garrison, field training, and deployment. In garrison, the day starts with physical training, followed by supply accountability work, requisition processing, inventory management, and coordination with supported units. Field training moves the officer into operational supply support, managing warehouses, coordinating material distribution, and establishing supply points in austere environments. Deployments put the officer in a forward operating environment with the expectation of providing uninterrupted supply support for the ground combat element.

The chain of command for a supply officer runs from the battalion S-4 to the regimental or MEF logistics officer to the commanding general. At the battalion level, the officer works directly with the S-1 on personnel logistics and the S-3 on operational planning. The officer-SNCO dynamic is critical in supply because the enlisted supply Marines bring years of hands-on technical experience with inventory systems and accountability procedures. A good working relationship produces a functional supply section. A poor one creates gaps in accountability and readiness.

Staff positions for 3002 officers include S-4 at the battalion level, company commander in a combat logistics battalion, supply planner at the MEF or MARFOR, and G-4 chief at the regiment or MEF level. At the MEF or MARFOR level, the officer shifts from unit-level execution to enterprise-level supply management, handling broader supply planning, resource allocation, and coordination with joint logistics partners. At Headquarters Marine Corps, senior supply officers work on supply architecture, policy development, and coordination with other services on joint supply operations.

The supply field has strong retention among officers who value clear operational support roles with strong civilian parallels. Officers who thrive in accountability, planning, and resource management tend to stay. Officers who prefer tactical field leadership or technical specialization often seek MOS changes or leave after their initial obligation. The job rewards attention to detail and systematic thinking. Good supply officers are remembered for their ability to keep the material flowing and their commanders informed.

Training and Skill Development

Pre-commissioning training varies by path. PLC candidates complete two six-week summer sessions at Quantico. OCC candidates attend a single 10-week session. NROTC students complete summer cruises and leadership labs throughout college. Naval Academy midshipmen follow a four-year integrated military and academic program.

All newly commissioned officers attend The Basic School at MCB Quantico, Virginia.

TBS covers infantry tactics, leadership, land navigation, planning, Marine Corps history, and values. Every Marine officer goes through the same curriculum regardless of their eventual MOS. Class standing at TBS matters for MOS assignment.

Officers selected for supply then complete supply-community follow-on education tied to the ground supply field. The training covers Marine Corps supply doctrine, inventory management systems, supply accountability procedures, and the logistics information systems used across the operating forces. The training ensures that 3002 officers arrive at their first billet with a working knowledge of the supply systems they will be responsible for managing.

Professional Military Education follows as officers progress. Expeditionary Warfare School is a resident Captain-level PME program at MCB Quantico. Command and Staff College serves Majors at Quantico. The School of Advanced Warfighting is a selective program for high-performing Majors. Senior officers attend the Marine Corps War College.

Additional schools and training opportunities include supply management courses, logistics certifications, and joint logistics education. Civilian education opportunities include fully funded graduate school programs and advanced degree programs through Tuition Assistance, which provides up to $4,500 per year and $250 per semester hour.

Career Progression and Advancement

The supply officer career timeline moves through a series of key developmental positions.

An O-1 or O-2 in field 30 typically serves as a supply platoon commander in a combat logistics battalion, an assistant S-4 at the battalion level, or a supply officer in a support role. The job at this rank is learning how Marine supply operations work at the ground level by running supply chains, managing inventory, and coordinating material distribution.

An O-3 usually serves as the battalion S-4, a company commander in a combat logistics battalion, or a supply planner at a MEF or MARFOR. At this rank, the officer owns the supply section and advises the commander on supply readiness and resource allocation.

An O-4 and above moves into G-4 chief, senior supply planner at a MEF or MARFOR, or staff billets at Headquarters Marine Corps and joint logistics commands. The work at this level involves supply architecture, policy development, and coordination with other services on joint supply operations.

Promotion from O-1 to O-3 is essentially time-based. O-4 and above require selection by promotion boards. Boards review fitness reports, professional military education completion, command performance, and overall record quality. Current promotion rates for supply officers at O-4 and O-5 track with the Marine Corps average.

Officers can change MOS through lateral move programs, typically after completing their first or second major assignment. Broadening assignments include recruiting duty, NROTC instructor, joint staff positions, Marine Security Guard, and fellowship programs.

Building a competitive supply officer record requires strong fitness reports, successful command performance, PME completion, and a record of sound judgment in resource management. The officers who advance are the ones who keep the supply system running and make the commander’s job easier.

Physical Demands and Medical Evaluations

Supply officers take the same PFT and CFT as all Marines. The physical demands of the job exceed the minimum standards. Supply officers may need to manage warehouse operations and coordinate material handling in the field, so physical fitness matters even though the job has an administrative component.

The mental demands of the 3002 role are significant. The work requires the ability to plan complex supply operations, manage multiple supply chains simultaneously, and make resource allocation decisions under pressure. Bad supply planning shows up fast in unit readiness and can directly affect the commander’s ability to execute the mission.

The job also requires strong attention to detail because supply accountability is a core Marine Corps value. Every piece of equipment has a dollar value and a readiness impact. The supply officer is responsible for making sure the system works and that the commander can trust the supply data.

3002 officers do not require flight physicals or dive physicals. They must pass the standard commissioning physical examination and maintain medical readiness for field deployment. Any condition that prevents an officer from working in a warehouse environment, managing material handling operations, or deploying with their unit would be disqualifying.

Deployment and Duty Stations

Supply officers deploy with their units on the MEU cycle or as part of larger task force packages. The S-4 does not stay behind when the battalion deploys. The supply section travels with the unit and sets up supply support in whatever environment the unit operates in.

Combat logistics battalion officers deploy as part of the Combat Logistics Regiment and provide direct support to maneuver units. The job during deployment involves managing supply routes, coordinating transportation assets, overseeing warehouse operations, and ensuring the maneuver units have the material they need to keep operating.

The operational tempo for 3002 officers tracks closely with their parent unit. During pre-deployment workup cycles, the supply section faces heavy preparation demands including equipment resets, supply prepositioning, and transportation coordination. During deployment, the tempo stays high because supply support never stops. Stateside periods between deployments focus on reset, individual training, and building readiness for the next cycle.

Primary duty stations for ground supply officers include Camp Pendleton, California; Camp Lejeune, North Carolina; MCB Quantico, Virginia; Marine Corps Logistics Base Albany, Georgia; Marine Corps Logistics Base Barstow, California; Marine Corps Base Hawaii; and Camp build, Okinawa. Officer duty station assignments are determined through the monitor system and the Marine Corps assignment process. Officers have fewer but larger installation options compared to enlisted Marines. Preference is considered, but the needs of the Marine Corps drive final assignments.

Risk, Safety, and Legal Considerations

The 3002 officer job carries inherent risks associated with working around heavy equipment, warehouse operations, and field supply support. Officers face physical hazards in warehouse and field environments, including heavy lifting, material handling, and the risk of equipment-related injuries. The risk profile differs from combat arms officers because the 3002 officer spends more time in supply management and less time in direct field combat, but the consequences of supply failures affect every unit that depends on material support.

Safety protocols follow the Operational Risk Management framework. Supply officers conduct ORM assessments before every supply evolution, training exercise, and deployment activity. They apply risk controls, brief their Marines on hazards, and maintain accountability for safety compliance. Warehouse safety and material handling procedures are central to the 3002 role because a single safety failure can result in injury or equipment damage.

3002 officers hold command authority under the UCMJ. Platoon commanders exercise nonjudicial punishment authority through their company commander. Company commanders have direct UCMJ authority over their Marines. Command climate surveys and equal opportunity requirements are mandatory. Relief for cause ends an officer’s command career and triggers a formal review process. The 3002 officer is also accountable for supply resource management, meaning poor oversight of equipment accountability can result in administrative or financial liability.

Impact on Family and Personal Life

The 3002 lifestyle affects families through frequent moves, deployment cycles, and the demands of a logistics management career. PCS tempo for supply officers follows the standard Marine Corps rotation schedule, with families moving every two to three years on average. Supply assignments tend to be at larger installations, which means better access to schools, healthcare, and spouse employment opportunities.

The Marine Corps provides support through MCCS programs, Military OneSource, Marine Corps Family Team Building, and spouse employment assistance programs. These resources help families manage the demands of military life. Supply officers generally have more predictable garrison schedules than combat arms officers, which can benefit family stability during non-deployment periods.

Dual-military couples in field 30 face the same co-location challenges as other Marine officers. The Marine Corps attempts to co-locate dual-military couples through the Joint Domicile program, but operational requirements often override preference. Family support during deployments falls on the at-home spouse, extended family, and unit family readiness programs.

Marine Corps Reserve

Supply capability exists across both the active component and the Marine Corps Reserve, which gives this field a better reserve story than many narrow specialties. Reserve supply units maintain readiness through monthly drill weekends, annual training, and periodic mobilizations. The exact billet mix depends on the reserve unit structure and current manning requirements.

Commissioning and Service Commitment

Reserve commissioning for the 3002 path follows the same process as active duty. PLC-R serves reserve-component candidates. NROTC students can sign reserve contracts. Active-duty officers can transfer to the reserve after completing their minimum service requirement.

The standard drill commitment consists of one weekend per month and two weeks of annual training. Supply officers may require additional training days for certifications, multi-week exercises, and pre-mobilization workups.

Pay and Benefits

An O-3 Captain in the Marine Corps Reserve earns drill pay based on the same pay table as active duty, prorated for drill periods. At the under-2-years rate of $5,534.10 monthly base pay, one drill period equals approximately $184.47, and a standard four-drill weekend totals roughly $737.88 in base pay before allowances. Annual training adds two weeks of full active-duty pay.

Reserve officers enroll in TRICARE Reserve Select, with a monthly premium of approximately $53 for individual coverage. This costs significantly less than civilian health insurance but requires premium payments that active-duty families do not face. Education benefits include Federal Tuition Assistance and GI Bill eligibility based on qualifying service.

The reserve retirement system is points-based. Twenty qualifying years are required for retirement, collected at age 60, reducible by 90 days for each 90 consecutive days of qualifying active duty. Reserve pensions are typically smaller than active-duty pensions due to fewer points accumulated per year.

Training, Promotion, and Command

Reserve 3002 officers have access to professional military education schools including Expeditionary Warfare School and Command and Staff College. Promotion timing follows reserve boards, which may differ in tempo from active-duty boards. Command billets exist at the company and battalion level within reserve supply units.

Mobilization and Civilian Careers

Mobilization frequency varies. Reserve supply officers can expect periodic Active Duty for Operational Support tours, operational support assignments, and potential deployments with typical mobilizations running 9 to 12 months.

Reserve service pairs well with civilian careers in supply chain management, inventory management, logistics coordination, operations management, and federal supply positions across DoD and other agencies. USERRA protects reserve officers from employment discrimination and guarantees reemployment rights.

Post-Service Opportunities

The 3002 skill set translates directly into supply chain management, inventory management, and logistics coordination roles in the civilian sector. Officers who have managed Marine supply operations understand inventory control, supply chain planning, resource allocation, and operational planning at a scale that most civilian supply chain roles never reach.

Common civilian career paths include supply chain management, inventory management, logistics coordination, operations management, and federal supply positions across DoD and other agencies. The combination of operational experience, leadership training, and supply chain expertise makes the 3002 background highly competitive in the logistics job market.

The GI Bill covers full in-state tuition at public universities and up to $29,920.95 per year at private institutions. Officers who served on active duty qualify for the full Post-9/11 GI Bill benefit, which includes a monthly housing allowance at the E-5 with dependents rate for the school ZIP code, plus an annual book stipend of $1,000. Many former 3002 officers pursue graduate degrees in supply chain management, business administration, or logistics to complement their military experience.

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

The ideal 3002 candidate values accountability, systematic thinking, and resource management. You should be comfortable managing complex supply operations, maintaining detailed records, and advising commanders on material readiness. The job rewards officers who are organized, detail-oriented, and able to keep multiple supply chains running simultaneously.

The job is not for candidates who want tactical field leadership or technical specialization in weapons or electronics. Supply officers manage systems and resources first. The work is essential but less visible than combat arms leadership. Candidates who want minimal administrative responsibility or who struggle with detail-oriented work will find better fits in other occupational fields.

Officers who thrive in supply value clear operational support roles with strong civilian parallels. The work builds directly into supply chain management, logistics coordination, and operations management careers. If you want a commission with a clean internal progression path and strong civilian transfer value, the 3002 is a solid fit. If you want to lead Marines in direct combat operations, consider other occupational fields.

For long-term career planning, the 3002 path leads to senior supply management positions, joint logistics staff roles, and HQMC policy billets. The civilian career transfer value is strong in supply chain management, inventory management, and operations management. If you want to grow into broader logistics leadership responsibility, this is a reliable path.
