2-124. Army operational planning requires the complete definition of the mission, expression of the commander’s intent, completion of the commander and staff estimates, and development of a concept of operations. These form the basis of a plan or order and set the conditions for a successful battle. The initial plan establishes the commander’s intent, the concept of operations, and the initial tasks for subordinate units. It allows the greatest possible operational and tactical freedom for subordinate leaders. It is flexible enough to permit leaders to seize opportunities consistent with the commander’s intent, thus facilitating quick and accurate decision making during combat operations. The plan not only affects the current operation, but it also sets the stage for future operations. (See ADRP 5-0 for doctrine on the operations process.)
