An operation order (OPORD) is a clearly defined order that precisely and concisely describes the mission, commander's intent, and concept of how to accomplish the mission. It is used by military units to communicate their plans and intentions to subordinate units and personnel. OPORDs are typically issued in writing, but can also be given verbally in fast-paced or time-sensitive situations.
