14-1. Planning and preparation accomplish nothing if the command does not execute effectively. Execution is putting a plan into action by applying combat power to accomplish the mission (ADRP 5-0). In execution, commanders, supported by their staffs, focus their efforts on translating decisions into actions. Inherent in execution is deciding whether to execute planned actions, such as changing phases or executing a branch plan. Execution also includes adjusting the plan based on changes in the situation and an assessment of the operation’s progress. (See ADRP 5-0 for fundamentals of execution).
