3-92. Reconstitution operations are extraordinary actions that commanders plan and implement to restore attrited units’ combat effectiveness commensurate with the mission requirements and available resources. Reconstitution restores combat power to the levels necessary to maintain endurance and continue operations. Reconstitution is not a sustainment operation although sustainment plays an integral part, and all sustainment functions are executed during reconstitution. Human resources, medical, supply, and maintenance personnel work closely with maneuver forces to rebuild combat power.
