Which rank is NOT held by the Commandant of the Air Cadet Regions?

The rank that is not held by the Commandant of the Air Cadet Regions is Flight Sergeant. In the context of the Air Cadets, the Commandant typically holds a commissioned officer rank, which in this case includes ranks such as Group Captain, Wing Commander, and Squadron Leader. These ranks are specifically designated for officer roles within the Royal Air Force and affiliated youth organizations.

Flight Sergeant, however, is a non-commissioned rank. Non-commissioned officers (NCOs) like Flight Sergeant play essential roles within the structure of the Air Cadets, but they do not have the authority and responsibilities associated with the rank of Commandant. The Commandant's position typically involves leadership and oversight at a regional level, functions that are performed by officers rather than NCOs. This distinction clearly sets Flight Sergeant apart from the ranks that are relevant for the role of Commandant in the Air Cadet Regions.
