  DISPLACEMENT CRITERIA
  5-23. Displacement criteria define triggers for planned withdrawals, passage of lines, or reconnaissance
  handovers (battle handover for security operations) between units. As with engagement,disengagement,and
  bypass criteria, the conditions and parameters set in displacement criteria integrate the BCT commander’s
  intent with tactical feasibility. Conditions and parameters are event-driven, time-driven, or enemy-driven.
  Displacement criteria conditions and parameters are key rehearsal events due to the criticality of identifying
  the triggers to anticipate during the BCT’s mission. An example of event-driven conditions and parameters
  are associated priority intelligence requirements being met, enemy contact not expected in the area, and
  observed named area of interest (NAI) or avenue of approach denied to the enemy. Time-driven conditions
  and parameters ensure the time triggers are met (for example, latest time information is of value). An
  observation post compromised by threat or local civilian contact is a threat-driven condition. Failure to dictate
  conditions and parameters of displacement,nested within the higher scheme of maneuver,results in mission
  failure.
  COMBINED ARMS, AIR-GROUND RECONNAISSANCE AND
  SECURITY
  5-24. The commander uses information and intelligence from combined arms, air-ground reconnaissance
  (and when available air and ground surveillance and military intelligence assets internal and external to the
  BCT) and security to reduce uncertainty and facilitate rapid decision-making. Reconnaissance collects
  information so the commander can understand the situation, visualize the battlefield, and shape decisions.
  Security protectsthe force,provide reaction time,and maneuver space to enable decisions and prudent use
  of combat power. The commander uses air-ground reconnaissance and securityto answer priority intelligence
  requirements to fill information gaps,mitigate risk,prioritize tasks,and allocate resources. Lastly,air-ground
  reconnaissance and security create advantageous conditions for future operations that seize, retain, and
  exploit the initiative.
  5-25. Army attack reconnaissance aircraft,both manned and unmanned,provide direct fire,observation,and
  rapid movement during reconnaissance and security and counterreconnaissance. Army attack reconnaissance
  units conduct Army aviation attacks to destroy high-value targets (HVTs)andHPTswithin a target area of
  interest (TAI). Army aviation attack reconnaissance aircraft can provide additional observation to assist
  reconnaissance and security forces, specifically the Cavalry squadron in maintaining contact. Utility and
  cargo helicopters support reconnaissance and security operations through air movements,(including casualty
  evacuation and emergency resupply operations) depending on the enemy’s air defense threat.
  Note.The same general planning considerations that apply to air assaults apply to air movements.
  (SeeFM 3-99 for additional information.)
  5-26. Air-ground operations require detailed planning of synchronized timelines,aviation task and purpose,
  and airspace management (see ATP 3-04.1). Shared graphics ensure common operational language,reduce
  fratricide risk,reduce the chance of an accidental compromise of a ground unit,and increase the effectiveness
  of mixing collection sources. Development of detailed mission statements for the supporting aviation is
  essential for aviation commanders and staffs to employ the right platforms and munitions. Understanding the
  threat and the commander’s intent and desired effects drives the aviation units’ task organization of air
  elements and selection of weapon systems. Aircraft fuel consumption rates, forward arming and refueling,
  and fighter management can limit aircraft availability.
  RECONNAISSANCE AND SECURITY FORCE SUSTAINMENT
  5-27. Sustainment for reconnaissance and security forces requires deliberate planning. Logistics units
  supporting reconnaissance and security operations must contend with long lines of communication,dispersed
  forces, poor trafficability, and contested terrain. Planners must consider protection requirements to protect
  sustainment units against bypassed enemy forces and the effects of extended lines of communications.
  Reconnaissance and security force sustainment must be rehearsed and wargamed.
