A group warship is a type of naval vessel that is composed of multiple ships, usually from the same country or organization. The term 'FLEET' is used to refer to a group of warships, and it is derived from the Latin word 'flota, ' which means 'a number of ships.' A FLEET is typically commanded by an admiral or other high-ranking naval officer, and it is used for a variety of purposes, such as patrolling, defending, and attacking.
