Defense Agencies and DoD Field Activities
Title 10 U.S.C. provides that: "Whenever the Secretary of Defense determines such action would be more effective, economical, or efficient, the Secretary may provide for the performance of a supply or service activity that is common to more than one military department by a single agency of the Department of Defense." Although Defense Agencies and DoD Field Activities perform similar support functions, in general, DoD Field Activities are smaller and serve a more limited portion of the Department than Defense Agencies. The ability to combine common services and supplies has proven beneficial in reducing redundancy among the military departments and conserving scarce resources through centralized management.
