TACON (tactical control) is a command authority that is made available for tasking and is used for movements or maneuvers within the operational area necessary to accomplish missions or tasks assigned. TACON is inherent in ________.

TACON, or tactical control, is inherently linked to operational control. This connection arises from the distinct definition of these command authorities and how they function within the military hierarchy. TACON provides the ability to direct forces to accomplish specific missions or tasks and encompasses authority over movements and maneuvering of those forces within a designated operational area.

Operational control is a broader command authority that encompasses various subordinate levels of command, including TACON. It allows commanders to exercise authority and control indirectly and is essential for effectively managing resources and conducting operations in a dynamic environment. By utilizing TACON under the umbrella of operational control, commanders can maintain situational awareness and exercise tactical flexibility to adapt to changing circumstances on the battlefield.

Other command types like Strategic Command, Direct Command, and Joint Operations refer to different levels or scopes of command authority, which do not inherently include tactical control in the same way that operational control does. Therefore, the link between TACON and operational control is the key reason why this answer is accurate.
