Who holds authority over forces such as individuals, units, and detachments for a specific service?

The authority over forces such as individuals, units, and detachments for a specific service lies with the Service Component Commander. This role is crucial because the Service Component Commander is responsible for the overall readiness and operational effectiveness of the forces assigned under their command. Their primary duties include ensuring that the forces are adequately equipped, trained, and prepared for missions, as well as managing personnel and resources effectively.

This authority encompasses the ability to direct operations, make staffing decisions, and allocate resources in alignment with the strategic objectives of their specific branch of the military. This position also acts as a critical link between the service and unified commands, ensuring that the service's capabilities are integrated appropriately within joint operations.

Other positions, while they hold significant roles in military operations, do not have the direct authority over individual service members and units in the same manner as a Service Component Commander. Regional Commanders may oversee broader geographical areas, and Joint Task Force Leaders manage specific operations that draw from multiple services, but they do not have the same level of authority over individual service component units. Operational Staff Officers often support with planning and execution but do not hold command authority over forces.
