What is the rank of an officer that typically commands a squadron in the Royal Air Force?

The rank that typically commands a squadron in the Royal Air Force is indeed Squadron Leader. This rank is unique in its designation to the role of leading a squadron, which is a fundamental operational unit in the RAF. Squadron Leaders are responsible for the overall effectiveness, performance, and leadership of their squadrons, overseeing personnel management, training, and operational readiness.

In the structure of RAF ranks, a Squadron Leader is positioned above a Flight Lieutenant and below a Wing Commander. While a Flight Lieutenant may lead a flight (a smaller unit within a squadron), they do not carry the same level of responsibility or authority as a Squadron Leader, who is in charge of a larger operational team. Group Captains hold a higher rank than Squadron Leaders and typically take on broader command roles, such as leading a group of squadrons or managing larger operational tasks. Wing Commanders operate at a higher level, often in charge of multiple squadrons or significant segments of RAF operations.

This context clarifies why the rank of Squadron Leader is the correct answer, as it directly correlates to the command structure of a squadron.
