text: Preface
  FM 4-0, Sustainment Operations augments ADP 4-0, the Army’s principal doctrine on providing sustainment
  in support of operations. It describes how Army sustainment forces, as part of the joint team, provide support
  to Army and other forces with an emphasis on support to operations. This manual serves as a companion
  manual to FM 3-0. FM 4-0 describes how the Army as part of a joint team is sustained during operations.
  The principal audience for FM 4-0 is all members of the profession of arms. Commanders and staffs of Army
  headquarters serving as a joint task force or multinational headquarters should also refer to applicable joint
  or multinational doctrine concerning the range of military operations and joint or multinational forces.
  Trainers and educators throughout the Army will also use this publication.
  Commanders, staffs, and subordinates must ensure that their decisions and actions comply with applicable
  United States, international, and in some cases host-nation laws and regulations. Commanders at all levels
  will ensure that their Soldiers operate in accordance with the law of armed conflict and the rules of
  engagement. (See FM 6-27/MCTP 11-10C.)
