Providing forces with the right fuel, in the right place, and at the right time involves determining peacetime and wartime requirements, contracting and allocating product, arranging for bulk storage, moving products forward to and within the theater, ensuring quality control, issuing and accounting for the fuel, and maintaining distribution equipment and facilities. Providing bulk petroleum support to joint operations requires the Services to develop complementary tactical distribution systems and the Defense Logistics Agency (DLA) to provide common products to the combatant commands (CCMDs) and Services. The nature of joint bulk petroleum support will vary depending on the commercial development of the theater, and whether force employment is single-Service, joint, or multinational. However, the Department of Defense (DOD) goal is a single-fuel concept (SFC). An SFC has benefits; one fuel is considerably easier to manage than multiple fuels, allowing the functions of fuel storage, transportation, and distribution to be tailored for maximum efficiency.
