  Army Operations Overview
  This chapter summarizes Army operations and provides guidance on their legal
  support. It addresses the shift from limited contingency operations to large-scale
  combat operations, the importance of the multidomain operations, and joint operations.
  The chapter then discusses the Army operational concept, operational framework, and
  Army echelons and units. Finally, the chapter addresses the capabilities, combat power,
  and the operations process and planning that enable the Army to support joint
  operations.
  LARGE-SCALE COMBAT OPERATIONS
  2-1. 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 operational environments, counter aggression on land during
  crisis, prevail during large-scale ground combat, and consolidate gains. The strategic roles clarify the overall
  purposes for which Army forces conduct multidomain operations on behalf of joint force commanders
  (known as JFCs) in pursuit of a stable security environment and other policy objectives that are favorable to
  the United States. The JAG Corps is manned, equipped, and trained to support a wide range of operational
  categories, including large-scale combat operations, limited contingency operations, crisis response, and
  support to security cooperation. JAG Corps personnel support Army operations during competition, crisis,
  and armed conflict. (See figure 2-1 for a depiction of the Army strategic context. See FM 3-0 for more
  information about the strategic contexts and operational categories.)

  2-2. JAG Corps personnel provide legal support during conventional and irregular warfare. Each of these
  methods of warfare involves different applications of lethal force, different rules of engagement, and different
  points of emphasis for Army forces. Legal support plays a key role in helping leaders and units navigate the
  legal challenges in any operational environment. (See FM 3-0 for more information about conventional and
  irregular warfare.)
