RN warrant officers and ratings can be qualified in either Minewarfare (MW) or Clearance Diving (D).  RN officers can be qualified in both Minewarfare and Clearance Diving (MCDOs) although some are qualified exclusively in Minewarfare (MWOs).  Officers serving in certain appointments also undertake the Advanced Minewarfare (AMW) course.
