An admiral is the commander of a fleet. In the navy, admiral is one of the highest ranks.

The military is full of rankings, such as captain, private, major, and corporal. Another is admiral, a ranking specific to the navy. While a captain is in charge of one ship, an admiral leads more than one ship: a bunch of ships, which are called a fleet. There are also a few different types of admirals, such as full admiral and vice admiral. Similarly, Battlestar Galactica’s Commander Adama becomes Admiral Adama as a result of leading more than one ship.
