5-29. Task-organizing is the act of designing a force, support staff, or sustainment package of specific size and composition to meet a unique task or mission. Characteristics to examine when task-organizing the force include, but are not limited to, the mission, training, experience, unit capabilities, sustainability, the operational environment, and the enemy threat. Task-organizing includes allocating assets to subordinate commanders and establishing their command and support relationships. This occurs within tailored force packages as commanders organize subordinate units for specific missions and employ doctrinal command and support relationships. As task-organizing continues, commanders reorganize units for subsequent missions. The ability of Army forces to task-organize gives them extraordinary agility. It lets commanders configure their units to best use available resources. It also allows Army forces to match unit capabilities to tasks. The ability of sustainment forces to tailor and task-organize ensures commanders have freedom of action to change with mission requirements.
