Who provides technical assistance to military personnel in delegated control areas?

The correct choice indicates that FAA personnel provide technical assistance to military personnel in delegated control areas. This arrangement is vital because the Federal Aviation Administration plays a key role in managing and coordinating aerospace operations, which includes offering support to military operations in shared airspace.

In delegated control areas, FAA personnel are responsible for ensuring that air traffic management is seamless and that military flights operate safely alongside civilian aviation. Their expertise in airspace management, navigation, and safety protocols enhances the operational efficiency and safety of military missions.

Other roles, such as command staff, ATC operators, and military liaisons, have distinct functions that do not primarily focus on the technical assistance aspect in this context. Command staff typically refers to the leadership and command structure of military operations; ATC operators manage air traffic but do not provide the same level of specialized assistance to military units as FAA personnel do; and military liaisons facilitate communication and cooperation but may not possess the requisite technical expertise in aviation operations.
