  12-25. The levels of detail and aggressiveness combine to give the commander four combinations of tempo
  to choose from. The four combinations of reconnaissance tempo are—
  * Rapid and forceful.
   Limited information requirements.
   Mission timeline emphasizes prompt collection.
   Overt movement is acceptable.
   Direct and indirect fires will not hinder or may enhance collection efforts.
  * Rapid and stealthy.
   Limited information requirements.
   Mission timeline emphasizes prompt collection.
   Covert movement is required.
   Direct and indirect fire contact will hinder collection efforts and movement and maneuver.
  * Deliberate and forceful.
   Extensive information requirements.
   Mission timeline allows comprehensive collection.
   Overt movement is acceptable.
   Direct and indirect fires will not hinder or may enhance collection efforts.
  * Deliberate and stealthy.
   Mission timeline allows detailed collection.
   Extensive information requirements.
   Covert movement is required.
   Direct and indirect fire contact will hinder collection efforts and movement and maneuver.
  12-26. It is less important that commanders use the specific terms (rapid or deliberate, forceful or stealthy)
  to communicate an organization's reconnaissance tempo. Instead, commanders should strive to provide
  guidance within each area of tempo to assist subordinate units in understanding how the reconnaissance effort
  is nested within the supported organization’s operating tempo. Generally speaking, commanders should
  inform the reconnaissance force how much information pertaining to the enemy and terrain they need to
  gather, how quickly that information must be gathered, and how aggressively to pursue that information.
  Engagement and Disengagement Criteria
  12-27. Engagement criteria are protocols that specify those circumstances for initiating engagement
  with an enemy force. Commanders must clearly define the size or type of enemy force they want their
  subordinate elements to engage or avoid. The commander ensures that subordinate leaders understand this to
  avoid becoming decisively engaged which prevents the unit from continuing reconnaissance operations.
  Commanders use bypass criteria to direct bypassing or handing off certain sizes or types of units to maintain
  the tempo of the operation based upon subsequent planned operations and guidance from higher. Bypass
  criteria are measures established by higher echelon headquarters that specify the conditions and size
  under which enemy units and contact may be avoided. Reconnaissance assets direct and rehearse
  handover of enemy targets between friendly units as required when specified enemy formations are bypassed.
  12-28. Disengagement criteria are protocols that specify those circumstances where a friendly force
  must break contact with direct fire and observed indirect fire to avoid becoming decisively engaged or
  to preserve friendly combat power. Just like engagement criteria, it is critical for the commander to clearly
  state when the subordinate elements must break contact with direct fire with enemy forces to prevent
  becoming decisively engaged and more importantly retain freedom of maneuver.
  CHARACTERISTICS OF RECONNAISSANCE ASSETS
  12-29. Every unit has a requirement to report information about the terrain, weather, civilian activities, and
  friendly and enemy dispositions. Troops in close combat and reconnaissance patrols of maneuver units at all
  echelons collect information on enemy units with which they are in contact. In echelon support areas, reserve
