9-68. Commanders should use tactical mission tasks or other doctrinally approved tasks contained in combined arms field manuals or mission training plans in mission statements. These tasks have specific military definitions that differ from standard dictionary definitions. A tactical mission task is a specific activity performed by a unit while executing a form of tactical operation or form of maneuver. It may be expressed as either an action by a friendly force or effects on an enemy force (ADRP 1-03). FM 3-90-1 describes each tactical task. FM 3-07 provides a list of primary stability tasks which military forces must be prepared to execute. Commanders and planners should carefully choose the task that best describes the commander’s intent and planning guidance.
