  figure5-2.) A reconnaissance handover lineis a designated phase lineon the ground where reconnaissance
  responsibility transitions from one element to another (FM 3-98). The reconnaissance handover line ensures
  control and chain ofcustody from the initial force to the force assuming responsibility and control.
  Figure 5-2. Reconnaissance handover, example
  5-55. Reconnaissance handover prevents gaps or seams to emerge that the enemy can exploit. Once
  handover is complete,the reconnaissance force transferring control either passes to the rear through the main
  body assuming responsibility for the reconnaissance objective as a rearward passage of lines or continues
  further into the zone to continue the reconnaissance mission. Reconnaissance handover assures that
  information requirements are transferred between units to maintain initiative,tempo,and to ease transitions.
  Well-plannedand executed reconnaissance handover eases transitions in plans,phases,and priorities of effort
  and mitigates information gaps between units.
  RECONNAISSANCE-PULL VERSES RECONNAISSANCE-PUSH
  5-56. Reconnaissance-pullis reconnaissance that determines which routes are suitable for maneuver,where
  the enemy is strong and weak,and where gaps exist,thus pulling the main body toward and along the path
  of least resistance. This facilitates the commander’s initiative and agility (FM 3-90-2). In reconnaissance-pull
  (see figure 5-3 on page 5-14), the commander uses the products of the IPB process in an interactive and
  repetitive way. The commander obtains combat information from available reconnaissance assets to
  determine a preferred COAfor the tactical situation presented by the mission variables of METT-TC.
