  are appropriate when time is limited,detailed reconnaissance is not required,terrain is open,environmental
  conditions allow for mounted movement, and when dismounted movement cannot complete the mission
  within existing time constraints. Forceful reconnaissance and security operations do not preclude the
  judicious use of dismounted movement to reduce risk as long as the organization maintains the tempo of the
  operation.

  FOCUS
  5-15. Focus for reconnaissance and security serves as a guide to indicate the tasks associated with the type
  of reconnaissance and security operation conducted although not a set checklist. Focus does not limit the
  reconnaissance and security forces’ ability to collect on and report all information but instead allows
  commanders to prioritize tasks to accomplish, and the assets used to accomplish them. Commanders help
  refine the focus of reconnaissance and security by describing the reconnaissance objective and security
  objective.
  Reconnaissance Objective
  5-16. Reconnaissance objective is a terrain feature, geographic area, enemy force, adversary, or other
  mission or operational variable about which the commander wants to obtain additional information
  (ADP3-90). The reconnaissance objective clarifies the intent of the reconnaissance effort by stating the most
  important result of the reconnaissance effort. A reconnaissance objective focuses the Cavalry (or other
  maneuver organization) organization’s area of emphasis. Four categories form the area of emphasis—threat,
  infrastructure,terrain and weather effects,and civil considerations. The commander often assigns more than
  one category to Cavalry units even though the commander recognizes that a broad focus in multiple areas
  dilutes the Cavalry organization’s ability to collect information. Narrowing the scope of operations helps to
  focus the Cavalry organization to acquire the information to develop the situation for future operations.
