Which term best describes the authority to perform functions of command over subordinate forces?

The term that best describes the authority to perform functions of command over subordinate forces is "Operational Control (OPCON)." This designation is important as it encompasses the responsibility for directing operational tasks and missions assigned to subordinate units or forces. OPCON allows a commander to organize and employ commands and forces, including the ability to assign tasks and allocate resources effectively.

Operational Control is distinct in that it permits the commander to make decisions on how forces are deployed and utilized within a particular operation or mission, providing a level of authority that is crucial for achieving operational objectives. It involves coordinating actions and ensuring that units work towards the same goals, which is vital for the success of military operations.

While other terms related to military authority, such as Direct Control, Strategic Authority, and Command Authority, exist, they denote different levels or aspects of military command. For example, Command Authority may refer more broadly to the overarching authority a commander has, while Direct Control typically implies immediate oversight over specific troops. Strategic Authority usually pertains to broader, long-term goals rather than the operational focus of OPCON. Therefore, Operational Control accurately captures the essence of the authority to command subordinate forces in a functional and mission-oriented context.
