1-70. The mission command approach to command and control requires active participation by personnel of all ranks and duty positions. Subordinate officers, noncommissioned officers, and Soldiers all have important roles in the exercise of mission command. During operations, subordinates are delegated authority, typically through orders and standard operating procedures, to make decisions within their commander’s intent. Commanders expect subordinates to exercise this authority to further the commander’s intent when changes in the situation render orders irrelevant, or when communications are lost with higher echelon headquarters.
