Divisions sit beneath squadrons or flotillas and split a large formation into smaller groups. Battleship Division Two, made up of four R-class ships, is the example here. An eight-battleship squadron can divide into two groups of four, while a destroyer flotilla of roughly twenty-five ships needs a different partition. Division size depends on the parent formation rather than a single fleet-wide rule.
