5-61. Route reconnaissance is a directed effort to obtain detailed information of a specified route and all terrain from which the enemy could influence movement along that route (ADRP 3-90). That route may be a cross country mobility corridor. Route reconnaissance provides new or updated information on route conditions, such as obstacles and bridge classifications, and enemy, adversary, and civilian activity along the route. Commanders normally assign this mission when wanting to use a specific route for friendly movement.
