The 4th Marine Division

[Sidebar (page 4):]The 4th Marine DivisionDepartment of Defense Photo (USMC) A707113Shoulder patch of the 4th Marine Division: a gold “4” on scarlet background, official colors of the U.S. Marine Corps. This emblem was designed by John Fabion, in the division’s Public Affairs Office before the Marshall campaign, and his commanding officer was astonished to find that the layout of the runways on the Japanese airstrip on Roi were “an exact replica.”Thisdivision was formed as the result of the organization and redesignation of several other units. The 23d Marines began as infantry detached from the 3d Division in February 1943, the same month that an artillery battalion of the 12th Marines became the genesis of the 14th Marines and engineer elements of the 19th Marines formed the nucleus of the 20th Marines. In March the 24th Marines was organized, and then in May it was split in two to supply the men for the 25th Marines.This war-time shuffling provided the major building blocks for a new division. The units were originally separated, however, with the 24th Marines and a variety of reinforcing units (engineer, artillery, medical, motor transport, special weapons, tanks, etc.) at Camp Pendleton in California. The rest of the units were at Camp Lejeune, North Carolina. This East Coast echelon moved to Pendleton by train and transit of the Panama Canal in July and August. When all the units were finally together, the 4th Marine Division was formally activated on 14 August 1943.After intensive training, it shipped out on 13 January 1944, and in 13 short months made four major assault landings: Roi-Namur, Saipan, Tinian, and Iwo Jima, suffering more than 17,000 casualties. It was awarded two Presidential Unit Citations and a Navy Unit Commendation, and then deactivated 28 November 1945. In February 1966, however, it was reactivated as the lead division in the Marine Corps Reserve, and major units later served with distinction in the Persian Gulf.
