I would't necessarily characterize it as "maverick" approach, but there is a historical rationale for the different culture. In the old days of wood ships and steel men, the Naval Officer was sent off to sea with only broad instructions. Communications were scarce, and voyages were long. The Naval Officer had to improvise, adapt to changed circumstances, and exercise independent judgment. In contrast, the Army was more tightly controlled, and less autonomous. The Air Force culture is passed down from the Army. (And yes, before we start a history debate, there were smaller Army units that operated independently in the West. There are exceptions to every rule, but the general explanation made sense to me). When I started the journey, Air Force was my first choice, but they wouldn't have me. I went Navy and never looked back. You really can't go wrong with either.
