Which of the following ranks has command over a larger unit than a squadron but less than a wing?

The rank of Group Captain commands a larger unit than a squadron but is subordinate to a wing. In the structure of the Royal Air Force, a Group Captain is responsible for several squadrons, typically commanding a group made up of multiple squadrons that operate together toward a common goal, often aligned with specific missions or operational objectives.

Command structures are tiered for effective management and coordination, with a squadron being a smaller unit typically composed of a specific number of aircraft and personnel. The next level up from a squadron is the group, which can include multiple squadrons under its command, thereby justifying the role of a Group Captain as overseeing these larger aggregates of forces. In contrast, a Wing Commander would be in charge of a wing, which is larger than a group, and a Squadron Leader has command only over a squadron. An Air Commodore is a more senior rank than a Group Captain, commanding at a higher organizational level, which further clarifies the hierarchy.

Thus, the structure and defined hierarchy within the RAF clearly identify Group Captain as the rank that fits the description of commanding a unit larger than a squadron and smaller than a wing.
