  combat power capabilities that support the JFC’s requirements. Tasks that the field armies may perform to
  support this function include—
  * Provide and coordinate sustainment support to assigned U.S. forces.
  * Anticipate requirements and develop plans for the employment of Army forces in limited
  contingency operations, crisis response operations, major operations, and campaigns.
  * Support other government agencies as directed by the combatant commander.
  * Provide sustainment and other directed support to multinational forces as required by the
  combatant commander.
  * Manage airspace.
  * Coordinate air and missile defense requirements.
  * Conduct area security operations.
  * Integrate cyberspace electromagnetic activities and space support into operations.
  * Command and control military deception efforts within the land area of operations.
  * Synchronize cross-domain ISR and information collection throughout the operational area.
  * Manage the electromagnetic spectrum in the operational area.
  * Protect Army, joint, and multinational networks.
  * Prepare to execute CWMD tasks.
  Assume Directed Army, Joint, and Multinational Authorities and Responsibilities
  3-133. During the course of operations to shape the operational area, the theater army or a JFC may grant
  the field army commander with additional authorities or responsibilities to facilitate operations. This is
  especially common during the transition to armed conflict. Although the exact requirements depend on the
  circumstances, key tasks that field armies may perform to support this function include—
  * Serve as the joint force land component command.
  * Serve as the multinational headquarters.
  * Assume additional directed Army authorities and responsibilities.
  * Assume additional directed joint authorities and responsibilities.
  * Assume military governance authorities and responsibilities.
  Shape an Assigned Operational Area
  3-134. During competition, field armies conduct operations to shape AOs. Although the field army’s
  emphasis is on deterring armed conflict and facilitating the rapid transition from competition to large-scale
  ground combat against peer threats, the field army may also execute operations that achieve competition
  objectives when properly resourced by the theater army or JFC. Key tasks that field armies may perform to
  support this function include—
  * Plan and prepare for large-scale combat operations.
  * Refine and conduct detailed planning for major operations to achieve competition objectives.
  * Refine and direct intelligence preparation of the battlefield.
  * Execute operations to achieve competition objectives.
  * Plan and execute flexible deterrent options and flexible response options.
  * Rehearse the transition from competition to large-scale ground combat.
  * Execute command and control over multiple corps-sized formations and other attached forces.
  Integrate Unified Action Capabilities to Support Unified Land Operations
  3-135. During conflict, Army forces in an AO must integrate unified action partners to achieve objectives
  effectively. This requires Army forces to both support unified action partners while also leveraging their
  capabilities to enhance unified land operations. Moreover, they must also prepare to synchronize partner
  capabilities to prevail in armed conflict, if necessary.
