What rank in the CAP signifies an individual as a squadron leader?

In the Civil Air Patrol (CAP), the rank of Captain signifies an individual as a squadron leader. This rank is essential within the structure of CAP, as captains typically assume command or leadership roles at the squadron level, which is the basic operational unit of the organization. A captain is responsible for overseeing the squadron's activities, ensuring adherence to CAP regulations, and leading cadet and senior members in training, missions, and events.

The other ranks mentioned serve different roles within the organization. For instance, while a Colonel usually signifies a higher position with more extensive responsibilities across multiple squadrons or a wing, a Major serves as an intermediate rank that may involve leadership roles but does not directly signify command of a squadron. A Lieutenant, meanwhile, is often a subordinate officer who may serve under a captain or other higher ranks. Therefore, the rank of Captain is specifically associated with leading a squadron, making it the correct answer.
