Sustainment Warfighting Function
Definition/Scope: (FM 3-0) The sustainment warfighting function is the related tasks and systems that provide support and services to ensure freedom of action, extend operational reach, and prolong endurance. The endurance of Army forces is primarily a function of their sustainment. Sustainment determines the depth and duration of Army operations. It is essential to retaining and exploiting the initiative. Sustainment provides the support for logistics, personnel services, and health service (excluding force health protection, which is a component of the protection warfighting function) necessary to maintain operations until mission accomplishment. Internment, resettlement, and detainee operations fall under the sustainment warfighting function and include elements of all three major subfunctions. FM 4-0 describes the sustainment warfighting function, and FM 4-02 discusses the Army Health System.
