At that point, they must take specific actions to return forces to combat effectiveness. The aviation force commander identifies the extent, distribution, and specific types of personnel and equipment losses. He also assesses residual combat capabilities. He then must coordinate with the theater, corps, or division commander and staff concerning needed replacements. Two major elements of reconstitution are reorganization and regeneration.
Reorganization is action to shift resources within a degraded unit to increase effectiveness.
Regeneration is the rebuilding of a unit through large-scale replacement of personnel, equipment, supplies, reestablishment of the chain of command, and training.
