Which command authority involves organizing and employing commands and forces?

The correct answer is indeed the designation referring to OPCON, or Operational Control. This command authority involves the ability to organize and employ commands and forces for missions. An entity with OPCON can direct and manage the operations and movements of forces to achieve specific objectives, allowing for significant flexibility in how assets are used in the operational space.

OPCON enables commanders to allocate resources, execute operational plans, and synchronize the efforts of different units under their command to accomplish the mission effectively. This level of control is essential for ensuring that various elements can work together seamlessly and respond dynamically to changing operational conditions.

In contrast, the other command authorities serve different roles: ADCON, or Administrative Control, focuses on the administrative and support functions necessary to maintain units but does not grant operational tasking. TACTCON, or Tactical Control, is more limited in scope, generally allowing for control over tactical operations within a specific area without the broader organizational influence that OPCON provides. ADMINCON also pertains to administrative tasks and does not involve the authority to organize or engage forces operationally.
