  DISENGAGE
  B-24. Disengage is a tactical mission task in which a unit breaks contact with an enemy to conduct
  another mission or to avoid becoming decisively engaged. It involves moving to a location where enemy
  forces cannot engage the friendly force with either direct fires or observed indirect fires. Disengaging from
  enemy forces while displacing from one position to the next is a difficult procedure. Figure B-12 depicts the
  disengage tactical mission task.
  B-25. A disengagement plan includes—
  * The maneuver concept of operations for tactical elements
  after disengagement, along with the movement routes for
  each subordinate unit.
  * Fires to suppress enemy forces and cover the unit’s
  movement.
  * Screening smoke to conceal the unit’s movement, as part
  of a military deception operation, or to cover passage
  points.

  * Contact and passage points if moving through friendly
  lines.
  * The time disengagement starts.
  * The earliest time that functional and multifunctional support and sustainment elements move.
  B-26. The senior headquarters conducts operations to support the disengaging forces and relieve pressure on
  units in contact with enemy forces. For example, if a division is conducting a delay, the division commander
  uses attached aviation assets to help a BCT disengage from close operations. Simultaneously, the division
  uses its long-range artillery, rocket, and electromagnetic warfare systems to destroy or disrupt enemy follow-
  on echelons to prevent them from interfering with the disengagement. The intent is to create conditions that
  allow the unit to disengage while avoiding decisive combat.
  B-27. To facilitate disengagement, units suppress the enemy force in contact by bombarding the enemy force
  with large volumes of both direct and indirect fires provided by forces other than the disengaging unit. In
  open terrain, a unit generally moves its short-range systems first. In close terrain, a unit generally moves its
  long-range systems first to support by fire positions. The time involved to move a system to its next position
  also affects when that system moves. Small-unit leaders usually direct this movement because of the limited
  range of combat net radios and the fact that the tactical situation varies across a unit’s front. This process is
  repeated as necessary. Once disengagement starts, units must complete it rapidly. A commander can employ
  supporting units or reserves to protect the disengaging unit’s flanks and assist in freeing any closely engaged
  elements. The unit then moves to its next position using the appropriate movement techniques.
  B-28. If enemy combat systems have not closed within direct fire range of the friendly disengaging unit, all
  its elements may be able to move simultaneously under the cover of massed fires and smoke. Speed of
  execution and continued coordination are essential to the success of this task.
  DISRUPT
  B-29. Disrupt is a tactical mission task in which a unit upsets an
  enemy’s formation or tempo and causes the enemy force to attack
  prematurely or in a piecemeal fashion. Units disrupt an enemy force
  by integrating direct and indirect fires, terrain, and obstacles. This
  increases an enemy force’s vulnerability to friendly fires. It may
  temporarily knock a unit out of a battle. Disruption is not an end; it is
  the means to an end. The center arrow points toward the targeted enemy
  unit. Figure B-13 depicts the disrupt tactical mission task.
  B-30. The maneuver force attempting to disrupt an enemy force must
  attack the defending enemy force with enough combat power to achieve Figure B-13. Disrupt task
  the desired results with one mass attack or sustain the attack until it
  achieves the desired results. It may involve attacking the enemy force while it is still in its assembly areas or
