  Figure 11-4. Example of a delay forward of a specified line for a specified time
  11-36. The second characteristic is that the commander must specify the acceptable level of risk for the
  security force to take. Acceptable risk ranges from accepting decisive engagement in an attempt to hold
  terrain for a given time to maintaining the integrity of the delaying force. The depth of the assigned area
  available for the delay, the time needed by the higher echelon headquarters, and the delaying force’s
  subsequent missions determine the amount of acceptable risk.
  11-37. The third characteristic is that the commander must specify whether the delaying force may use the
  entire assigned area or must delay from specific BPs. A delay using the entire assigned area is preferable, but
  a delay from specific positions may be required to coordinate two or more units in the delay. To enhance
  command and control and to coordinate the battle across a broad front, commanders can assign specific BPs
  down to platoon level. Commanders may direct units to delay within their assigned area if that best supports
  the scheme of maneuver.
  Command and Control in a Delay
  11-38. Communications are essential to the success of this variation of a retrograde, and commanders build
  redundancy into the communications architecture. Digital and analog systems help ensure redundancy by
  providing a COP. This allows one command post to temporarily assume the duties of another command post
  if it is destroyed, displaced, or has suffered an enemy cyberspace or electromagnetic attack.
  11-39. While planning a delay, the main command post is normally the first command post to displace,
  leaving the tactical command post to control the delay until the reestablishment of the main command post
  in a secure location. The main command post may displace by echelon, leaving a residual command and
  control capability in the original location.
