THE D-SERIES MARINE DIVISION |
First outlined in March 1941, the D-100 series table of organization formed the basis of the Marine divisional structure of the early war period. The D-series table of organization was modified in January 1942, and again in its final configuration on 1 July 1942. Divisions organized under T/O D-100 fought in the Solomon Islands campaigns. The First and Second and Third Marine divisions all utilized the D-100 table of organization early in their wartime careers.
