  3-20. During the planning process, the ground maneuver commander integrates the employment of attack
  or reconnaissance unit attacks into the scheme of maneuver to ensure their responsiveness, synergy, and
  agility during actions on the objective or upon contact with the enemy. Pre-mission development of control
  measures provides a foundation for the successful integration of Army Aviation into the unit’s operations.
  Among these control measures are engagement criteria; the triggers and conditions for execution; and fire
  coordination measures (such as TRPs, engagement areas, and ACMs [such as aerial ingress and egress
  routes and ROZs]).
  3-21. Shared understanding within the combined arms team, through known standardized procedures and
  habitual training, increases the likelihood of successful employment of attack or reconnaissance units
  against enemy forces in close contact with friendly forces. However, during in extremis situations, Army
  Aviation attack or reconnaissance units may conduct hasty attacks in support of all friendly ground units
  regardless of their training level or habitual relationship, but with greater risk. The use of the standardized
  Army attack aviation call for fire ensures the minimum mission essential information is provided from the
  ground commander in contact to the attack air mission commander.
  3-22. To maintain shared understanding and prevent burdening the commander in contact during
  execution, the attack or reconnaissance unit conducting hasty and deliberate attacks against enemy forces in
  close friendly contact monitors the primary supported ground unit voice command net and uses C2
  information systems (such as Blue Force Tracker) to gain and maintain situational understanding of
  friendly forces. Use of these systems and effective pre-mission planning enables Army Aviation attack or
  reconnaissance units to rapidly execute actions on contact and mitigates the risk of fratricide.
  3-23. When conducting attacks against enemy forces in close friendly contact, targets may range from
  hundreds of meters to several thousand meters from friendly forces. The attack or reconnaissance unit uses
  terrain and the mutual protection of ground maneuver forces to vary attack headings to remain
  unpredictable and limit exposure to enemy fires. Once the engagement is complete, the attack or
  reconnaissance unit air mission commander provides the ground commander with BDA. The air mission
  commander also provides a follow-on recommendation, such as re-attack, execution of a follow-on task, or
  end-of-mission.
