1-162. Decisive, shaping, and sustaining operations lend themselves to a broad conceptual orientation. The decisive operation is the operation that directly accomplishes the mission (ADRP 3-0). It determines the outcome of a major operation, battle, or engagement. The decisive operation is the focal point around which commanders design an entire operation. Multiple subordinate units may be engaged in the same decisive operation. Decisive operations lead directly to the accomplishment of a commander’s intent. Commanders typically identify a single decisive operation, but more than one subordinate unit may play a role in a decisive operation.
