A Fleet Admiral is a high-ranking officer in the naval forces, typically the highest possible rank in a navy. This title is often reserved for wartime leaders and is equivalent to a five-star general in the army. Fleet Admirals command large naval fleets and are responsible for strategic planning and operations at sea. The rank of Fleet Admiral is rare and has been held by notable figures such as William D. Leahy, Ernest King, and Chester W. Nimitz in the United States Navy. This position requires extensive experience and leadership skills, as it involves overseeing multiple ships and coordinating complex military missions.
