Diversion Attack Force Doctrine

In August 1943 Combined Fleet issued a memorandum abolishing the Advance Force and moved all the battleships and cruisers previously assigned to the Main Force and Advance Force, together with their screen, to the Diversion Attack Force (Yugeki Butai), as the old terminolgy was "not suited to the style of present operations"; i.e. carrier mobile or strike force operations. On January 1, 1944 Commander Second Fleet (Admiral Kurita) issued Diveresion Attack Force Doctrine.
