The term 'kind of admiral' refers to two different types of naval officers. REAR Admiral is a senior naval officer rank, typically above a Commodore and below a VICE Admiral. REAR Admirals are usually in command of a squadron or a large independent ship. VICE Admiral is the second highest active rank of the navy, typically above a REAR Admiral and below an Admiral. VICE Admirals are usually in command of a fleet or a major naval base.
