  ARMY OPERATIONS
  2-51. 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 on land during crisis, prevail during
  large-scale combat, and consolidate gains. The Army fulfills its strategic roles by providing forces for joint
  campaigns that enable the integrated deterrence of adversaries outside of conflict and the defeat of enemies
  during conflict or war.
  2-52. Army forces achieve objectives through the conduct of operations. An operation is a sequence of
  tactical actions with a common purpose or unifying theme (JP 1, Volume 1). Operations vary in many ways.
  They occur in all types of physical environments, including urban, subterranean, desert, jungle, mountain,
  maritime, and arctic. Operations vary in scale of forces involved and duration. Operations change various
  conditions in the human, information, and physical dimensions of an OE and how these dimensions
  interrelate.
  2-53. The complex environment in which operations occur demands leaders who understand both the science
  and art of operations. Understanding the science of operations—such as combat power ratios, weapons
  ranges, and movement tables—assists leaders in improving synchronization and reducing risk. However,
  there is no way to eliminate uncertainty, and leaders must exercise operational art to make decisions and
  assume risk. Intangible factors, such as the impact of leadership on morale, using shock effect to defeat enemy
  forces, and supportive populations, are fundamentally human factors that can overcome physical
  disadvantages and often decide the outcomes of an operation.
  2-54. Army forces must be prepared for the most demanding and dangerous types of operations. Army forces
  contribute to conventional deterrence through their demonstrated capability, capacity, and will to wage war
  on land in any environment against any opponent. Credible combat forces with lethal capabilities make the
  other instruments of national power more potent, and they assist in deterring the enemy’s escalation of
  violence during other types of operations. (See FM 3-0 for doctrine on Army operations.)
  2-55. Effective and flexible intelligence support assists the Army with the challenges and complexity
  associated with a broad variety of and significant differences between the types of Army operations and the
  OE factors that affect those operations. Army commanders, staffs, and the intelligence warfighting function
  must leverage the intelligence enterprise and fight for intelligence to grapple with these issues. While
  intelligence is complex and threats, especially peer threats, can counter at least some of the intelligence
  capabilities and collection assets, Army commanders and staffs can overcome these issues. Every Army
  echelon can mitigate these challenges through the commander owning the intelligence effort, effective staff
  integration, and creative and adaptive information collection to overcome existing information collection
  gaps. Together, these aspects of fighting for intelligence ensure success, whether the operation is a large-
  scale combat operation, foreign humanitarian operation, counterinsurgency, foreign internal defense, or a
  noncombatant evacuation.
  MULTIDOMAIN OPERATIONS
  2-56. Multidomain operations is 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). Employing Army and joint capabilities makes use of all available
  combat power from each domain to accomplish missions at the least cost. Multidomain operations are the
  Army’s contribution to joint campaigns, spanning the competition continuum. Below the threshold of armed
  conflict, multidomain operations are how Army forces accrue advantages and demonstrate readiness for
  conflict, deterring adversaries while assuring allies and partners. During conflict, they 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.
