7-129. A movement to contact mission requires the commander not to have contact with the enemy main body. However, the commander may still know the location of at least some enemy reserve and follow-on forces. If the corps or division commander has enough information and intelligence to target enemy uncommitted forces, reserves, or sustaining activities, the commander normally designates forces, such as long-range artillery systems, attack helicopters, extended-range UASs, and fixed-wing aircraft to engage known enemy elements regardless of their locations within the AO. At all times the forward security element and the main body perform information collection. Reconnaissance is largely force oriented and not as detailed as a typical zone reconnaissance that gathers detailed information on both the enemy and terrain. The terrain reconnaissance tasks are minimized to only those necessary to facilitate mobility of the force.
