  Sustainment
  Sustainment operations provide support and services to ensure freedom of action,
  extend operational reach, and prolong endurance. Brigade combat team (BCT)
  sustainment organizations synchronize and execute sustainment operations in support
  of the BCT under all conditions to allow the BCT to seize, retain, and exploit the
  initiative. BCT subordinate units and sustainment staffs anticipate future needs to
  retain freedom of movement and action at the end of extended and contested lines of
  operation. The brigade support battalion (BSB) commander is the BCT’s senior
  logistician. The BSB commander is responsible for sustainment synchronization and
  execution across the BCT’s area of operations. This chapter describes sustainment
  operations in support of the BCT, specifically the functions, command and staff roles
  and responsibilities, and unit relationships throughout high tempo and decentralized
  operations.
  SECTION I – FUNDAMENTALS OF SUSTAINMENT
  9-1. Sustainmentis the provision of logistics, financial management, personnel services, and health service
  support necessary to maintain operations until successful mission completion (ADP 4-0). Sustainment within
  the BCT is a brigade wide responsibility; commanders at all levels and the various staffs, as trusted Army
  professional and stewards of the Army Profession, have a role to ensure sustainment support is ethically,
  effectively, and efficiently planned, understood, and executed. Sustainment must be coordinated and
  synchronized to facilitate the operational pace and support the commander’s priorities before, during, and
  after operations. Staffs and planners must fully integrate sustainment throughout the operations process. (See
  ADP 4-0 and FM 4-0 for additional information.)
  SUSTAINMENT WARFIGHTING FUNCTION
  9-2. The sustainment warfighting function is the related tasks and systems that provide support and services
  to ensure freedom of action, extend operational reach, and to 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 necessary
  to maintain operations until mission accomplishment. The sustainment warfighting function consists of four
  major elements: logistics, financial management, personnel services, and health service support.
  Paragraphs9-3 through 9-6 discuss the functional elements found in each of the sustainment elements
  applicable to the BCT.
  LOGISTICS
  9-3. Logisticsis planning and executing the movement and support of forces. It includes those aspects of
  military operations that deal with: design and development, acquisition, storage, movement, distribution,
  maintenance, evacuation, and disposition of materiel, acquisition or construction, maintenance, operation,
  and disposition of facilities, and acquisition or furnishing of services (ADP 4-0). The elements of logistics
  make up the distinct function of logistics. The elements of logistics (see FM 4-0)within the BCT includes—
  (cid:122) Maintenance. (See ATP 4-33.)
  (cid:122) Transportation. (See FM 4-01.)
  (cid:122) Supply. (See FM 4-40.)
