6-184. The actual reconnaissance begins at the designated transition point and ends with a follow-on transition to tactical movement away from the reconnaissance objective. Leaders mark the follow-on transition point with a control measure similar to the first transition point, using a linkup point, rendezvous point, a LOA, or a phase line. During this phase, leaders execute one of the three forms of reconnaissance (area, zone, or route). These forms of reconnaissance are distinguished by the scope of the reconnaissance objective. The forms of reconnaissance patrols Infantry units conduct are area, zone, and route. (See figure 6-15.)
6-185. To plan for a reconnaissance, use the reverse-planning process. The leader first determines the reconnaissance objective, an information requirement corresponding to the terrain or enemy in a specific area, route, or zone; it may be designated by a control measure such as named areas of interest, checkpoints, objective, route, phase lines, or boundaries. Once the leader has clarified the reconnaissance objective, he determines the observation plan enabling the patrol to obtain the information required. After determining the observation plan, the leader determines the tactical movement necessary to position the patrol to achieve his observation plan.
