The Supply Chain Material Management occupational field includes personnel in the areas of ground supply chain management operations, inventory management, preservation and packaging, hazardous materials storage and handling operations, fiscal accounting and purchasing, and contracting procedures pursuant to the Federal Acquisition Regulations. Duties involve administrative procedures, familiarization with state, Federal, and Department of Defense (DoD) regulations, and the use of material handling equipment in the movement and storage of materiel and equipment.

In all MOSs within the occupational field, technical skills are required regarding military and commercial specifications on materiel and equipment being procured, stored, and maintained. These skills and duties must be performed in garrison, afloat, expeditionary and combat environments. These Marines are required to have an operational understanding in executing supply chain functions and programs, some of which are unique to the service and DoD as well as provide for effective and efficient end-to-end materiel support in the area of material management. Marines assigned to the occupational field are trained to utilize data scanning, and retrieval devices; office and inventory management procedures; automated information data entry and external systems interface procedures; asset accounting functions; financial budget formulation; management and analysis; and the proper handling, storage, and disposal of hazardous material.

What is an 3002?

Ground Supply Officers are a special Staff Officer that supervises the Commanders’ Property, Plant, & Equipment (PP&E) and Operating Material & Supplies (OM&S) to ensure data accuracy, existence, and completeness (equipment accountability, visibility, and auditability). They supervise and coordinate ground supply administration and operations for supply activities, units, bases, or stations, to include operating forces and shore station organizations. Ground Supply Officers may direct the activities of a maintenance distribution or industrial type organization. They command or serve in either an operating forces service unit or a non-operating forces activity. Ground Supply Officers supervise the execution of supply chain management policies and procedures pertaining to: procurement; receipt; inventory control; repair; storage; distribution; issue; disposal; and computation and maintenance of stock positioning requirements. They provide supply support insight for operational planning requirements; supervise transportation of supplies and equipment; manage the transmittal of public funds; participate in the budget process, administer, and expend allotted funds; and make necessary recommendations to the Commanding Officer regarding supply support procedures.

What is it like being a Ground Supply Officer?

The support provided by Ground Supply Officers is required aboard every major Marine Corps installation and in units across the MAGTF. A typical first-tour assignment for a Supply Officer is as the OIC of a Supply Section within an O-5 (Lieutenant Colonel) level command at a battalion or squadron. Ground Supply Officers serve as special staff officers to the Commanding Officer, managing unit property records and supervising the procurement of all requests for supplies and services. Additionally, they serve as the fiscal officer and manage the unit’s budget.
