Which control is always retained by the service component commander?

The correct choice is that administrative control is always retained by the service component commander. This type of control refers to the authority over subordinate organizations, personnel management, and resource allocation within the service component. The service component commander is responsible for overseeing administrative tasks such as personnel assignments, training, logistics, and resource management, which are essential for maintaining an effective and efficient organization.

In the context of military operations, administrative control is distinct from operational or combat control. Operational control involves directing forces to accomplish specific missions, usually delegated to commanders in the field. Combat control is a more specific subset focused on the direct engagement and maneuvering of forces during combat situations. Strategic control deals with broader, higher-level planning and resource allocation across multiple commands, which may involve coordinating with joint forces. However, the service component commander maintains administrative control to ensure that the unit remains capable and prepared for operations, regardless of other control structures in place for operational effectiveness.
