What organizational entity is responsible for administrative control of all members assigned to a unit?

The organizational entity responsible for the administrative control of all members assigned to a unit is the squadron section. This is because the squadron section serves as the foundational unit within the military structure, focusing on managing personnel, resources, and day-to-day operations. It ensures that all members are properly accounted for, trained, and supported in their roles.

The squadron is typically tasked with overseeing the administrative functions that include personnel administration, discipline, assignments, and unit readiness, making it the primary group that handles matters related to personnel administration for its assigned members. In this context, its direct oversight enables effective communication and management within the unit, which is essential for operational effectiveness.

Major commands, field operating agencies, and independent groups, while they play significant roles in broader operational structures, do not have the same direct responsibility for administrative control over individual members within a unit that a squadron section possesses. Each of these entities may oversee multiple squadrons or units, but their scope is generally more strategic than the squadron's direct management of personnel.
