text: The Defense
  Figure 8-1. Example detachment left in contact
  8-46. When a DLIC is used, commanders create an additional security force behind the existing main
  defensive positions to assist the withdrawal process. They can create an additional force from the
  withdrawing unit or from an assisting unit. The DLIC can conduct a delay for this additional security force
  and then join it, or the DLIC can conduct a battle handover and then conduct a rearward passage of lines. In
  either case, the additional security force becomes the rear guard.
  Civil Considerations
  8-47. Units’ defensive concepts of operations address how the preparation and conduct of the defense will
  influence the civilian population in their assigned areas. This includes the conduct of noncombatant
  evacuation operations for U.S. civilians and other authorized groups. Commanders have legal obligations to
  civilian populations in their assigned areas. Ideally, the local nation government will have the capability to
  conduct the six primary stability tasks. Defending units conduct only those minimum-essential stability tasks
  required by the mission variables and expend only the minimum-essential resources to meet their legal and
  ethical responsibilities to civilians during the execution of a defense.
  MOVEMENT AND MANEUVER
  8-48. Defending units intend to defeat an enemy force’s attack by overwhelming it with direct and indirect
  fires before it conducts its final assault on friendly defensive positions. As an enemy force’s attack fails, it
  attempts to withdraw or transition to a defense in the face of friendly counterattacks. If enemy forces succeed
  in overrunning a key defensive position, the defending force counterattacks to overwhelm enemy forces
  before they can either organize a defense or exploit their initial success.
  Exploit the Advantages of Terrain
  8-49. Units exploit the advantages of occupying the terrain where the battle will occur. The defending force
  engages the attacker from locations that give the defending force an advantage. These locations include
