    Two of the ocean minesweepers and minesweeping ships, assigned to this command [Agile and Bulwark (MSO 425)] assigned to this command. Small and compact, they have the dangerous mission of searching for enemy mines, locating them by electronic and magnetic means, and destroying enemy mines after they have been located
