  • Improvisation. Sustainment leaders must be able to improvise operational and tactical actions to
  meet a changing operational environment (OE).

  SECTION II – OVERVIEW OF ARMY OPERATIONS
  1-11. The Army’s primary mission is to organize, train, and equip its forces to conduct prompt and sustained
  land combat to defeat enemy ground forces and seize, occupy, and defend land areas. It supports four strategic
  roles for the joint force. Army forces shape OEs, counter aggression during crisis, prevail during large-scale
  ground combat, and consolidate gains. The Army fulfills its strategic roles by providing forces for joint
  campaigns that enable integrated deterrence of adversaries outside of conflict and the defeat of enemies
  during conflict or war. Sustainment supports the Army in achieving its primary mission through the provision
  of logistics, financial management, personnel services, and HSS. The integration and synchronization of each
  element of the sustainment warfighting function is essential in enabling freedom of action, extending
  operational reach, and prolonging endurance. The integration and synchronization of the sustainment
  warfighting function with the other warfighting functions is key to success during operations.
  1-12. Multidomain operations are the combined arms employment of joint and Army capabilities to create
  and exploit relative advantages to achieve objectives, defeat enemy forces, and consolidate gains on behalf
  of joint force commanders (FM 3-0). Multidomain operations span the competition continuum and are the
  Army’s contribution to joint campaigns. Sustainment supports the Army’s execution of multidomain
  operations through the provision of task-organized sustainment capabilities that support maneuver forces at
  echelon. Task-organized sustainment capabilities conduct sustainment operations across all domains to
  support and sustain large-scale combat operations. Below the threshold of armed conflict, multidomain
  operations are how Army forces accrue relative advantages and demonstrate readiness for conflict, deterring
  adversaries while assuring allies and partners. During conflict, multidomain operations are how Army forces
  close with and destroy the enemy, defeat enemy formations, seize critical terrain, and control populations
  and resources to deliver sustainable political outcomes (FM 3-0).
