  Army Sustainment Operations
  This chapter introduces Army sustainment operations, presenting the four elements of the
  sustainment warfighting function and examining the foundational principles underpinning
  sustainment. Moreover, it offers insights into Army operations and the challenges pertaining to
  sustainment that emerge within the competition continuum, a dynamic spectrum encompassing
  phases from peaceful competition to potential armed conflict. The chapter delves into Army
  sustainment forces operations and contributions within the strategic environment. The chapter
  culminates by delineating the provisions for sustaining multidomain operations, outlining the
  scope of authority and duties delegated to combatant commanders and explaining the requisites
  for Title 10 sustainment alongside the diverse responsibilities assumed by various executive
  agents.
  SECTION I – OVERVIEW OF ARMY SUSTAINMENT
  1-1. For the Army, sustainment is the provision of logistics, financial management, personnel services, and
  health service support necessary to maintain operations until successful mission completion (ADP 4-0).
  Sustainment is accomplished through the integration and synchronization of national and global resources
  and ensures Army forces are physically available and properly equipped, at the right place and time, to
  support the combatant commander (CCDR). The sustainment warfighting function leverages joint,
  interagency, intergovernmental, multinational, and other available capabilities to provide sustainment
  support to the force.
  1-2. Sustainment improves force readiness and maintains Army forces by manning them with trained Soldiers
  and leaders; funding them with required resources; equipping them with materiel (individual and unit);
  maintaining Soldier and Family readiness; and enabling Army forces to conduct operations. Army
  sustainment is based on and enabled by an integrated process (people, systems, materiel, health service
  support [HSS], and other support), inextricably linking sustainment to operations. Sustainment operations
  focus on building an operationally ready Army, delivering it to the CCDR as part of the joint force, and
  sustaining its combat power across the depth of the operational area.
  SUSTAINMENT WARFIGHTING FUNCTION
  1-3. The sustainment warfighting function is the related tasks and systems that provide support and services
  to enable freedom of action, extend operational reach, and prolong endurance (ADP 3-0). A collection of
  select primary related tasks that are embedded in the sustainment warfighting function are described in
  chapter 2. Systems consist of personnel, networks, information systems, processes and procedures, and
  facilities and equipment that enable sustainment commanders to support operations. The sustainment
  warfighting function consists of four elements: logistics, financial management, personnel services, and HSS,
  each of which must be integrated and synchronized across all warfighting functions to ensure the appropriate
  level of support. For additional information see ADP 3-0, ADP 4-0, and FM 3-0.
  LOGISTICS
  1-4. The elements of logistics are maintenance, transportation, supply, field services, distribution, operational
  contract support (OCS), and general engineering. Appendix A, Quartermaster Operations, describes supply,
  field services, and liquid logistics. Appendix B, Transportation Operations, describes the transportation
  elements of logistics. Appendix C, Ordnance Operations, describes the maintenance element of logistics and
  discusses ammunition and explosive ordnance disposal (EOD).
  FINANCIAL MANAGEMENT
  1-5. Financial management provides support to the Army and its unified action partners through the execution
  of the two core competencies of finance operations and resource management. Finance operations consists
