  ⚫ Adjusting to shifts in the unit and subordinate rear boundaries.
  ⚫ Integrating new units into corps and divisions.
  8-50. Intelligence support to rear operations focuses on ensuring operational and tactical gains achieved
  during operations are not lost and the tempo of operations in close and deep areas is maintained. IPOE and
  information requirements related to sustainment operations include but are not limited to—
  ⚫ Gaining and maintaining information concerning threat activities and intentions such as—
  ▪ Threat capabilities that may impact sustainment operations.
  ▪ Bypassed forces that may impact rear operations.
  ▪ Threat capabilities that may impact freedom of maneuver for friendly forces through the AO.
  ▪ Threat long-range fires capabilities.
  ⚫ Support to security activities.
  ⚫ Support to protection activities.
  ⚫ Activities to consolidate gains.
  ⚫ Support to developing and implementing stability mechanisms.
  ⚫ Key and decisive terrain associated with rear operations.
  ⚫ Support to echelons conducting consolidating gains activities.
  ⚫ Support to protection and security operations.
  ⚫ Support to information advantage activities.
  ⚫ Information gaps in rear operations intelligence and developing collection strategies to fill the gaps.
  SETTING CONDITIONS: ENABLING OPERATIONS
  8-51. There are many important aspects of offensive and defensive operations, including enabling
  operations. An enabling operation is an operation that sets the friendly conditions required for mission
  accomplishment (FM 3-90). The nine types of enabling operations are—
  ⚫ Reconnaissance. ⚫ Countermobility.
  ⚫ Security operations. ⚫ Mobility.
  ⚫ Troop movement ⚫ Tactical deception.
  ⚫ Relief in place. ⚫ Linkup.
  ⚫ Passage of lines.
  8-52. Reconnaissance and security operations are the enabling operations most important to the intelligence
  warfighting function. In combat, seizing the initiative involves conducting reconnaissance, maintaining
  security, conducting defensive and offensive operations at the earliest possible time, forcing the enemy to
  culminate offensively, and setting the conditions to prevail.
  Reconnaissance
  8-53. Commanders normally assign reconnaissance objectives, which can be a specific geographic location,
  a specific enemy activity to be confirmed or denied, or a specific enemy unit to be located and tracked.
  Reconnaissance objectives can focus on any operational or mission variable about which the commander
  wants to obtain additional information. Therefore, every reconnaissance is different and there is no general
  list of information requirements. The following are the five types of reconnaissance operations:
  ⚫ Zone reconnaissance is a form of reconnaissance operation that involves a directed effort to
  obtain detailed information on all routes, obstacles, terrain, and enemy forces within a zone
  defined by boundaries (FM 3-90). Commanders assign a zone reconnaissance when they need
  additional information on a zone before committing other forces.
  ⚫ Area reconnaissance is a form of reconnaissance operation that focuses on obtaining detailed
  information about the terrain or enemy activity within a prescribed area (FM 3-90). This area
  may consist of a single location, such as a town, a ridgeline, a forest, an airhead, a bridge, an
  installation, or any other critical operational feature such as obstacles.
