* These final Marine casualty figures were compiled from records furnished by Statistics Unit, Personnel Accounting Section, Records Branch, Personnel Department, HQMC. Figures for the Peleliu Operation were certified and released on 1 June 1950; those for Iwo Jima in August 1952. Naval casualties were taken from NavMed P-5021, The History of the Medical Department of the Navy in World War II (Washington: Government Printing Office, 1953). The key to the abbreviations used at the head of columns in the table follows: KIA, Killed in Action; DOW, Died of Wounds; WIA, Wounded in Action; MIAPD, Missing in Action, Presumed Dead. Because of the casualty reporting method used during World War II, a substantial number of DOW figures are also included in the WIA column.
