Note (Back) — CHAPTER 4
Reading edition
The increased allotment of black troops entering the corps and the commandant's call for replacing all white noncommissioned officers with blacks as quickly as they could be sufficiently trained caused problems for the black combat units. The 51st Defense Battalion in particular suffered many vicissitudes in its training and deployment. The 51st was the first black unit in the Marine Corps, a doubtful advantage considering the frequent reorganization and rapid troop turnover that proved its lot. At first the reception and training of all black inductees fell to the battalion, but in March 1943 a separate Headquarters Company, Recruit Depot Battalion, was organized at Montford Point.[4-28] Its cadre was drawn from the 51st, as were the noncommissioned officers and key personnel of the newly organized ammunition and depot companies and the black security detachments organized at Montford Point and assigned to the Naval Ammunition Depot, McAlester, Oklahoma, and the Philadelphia Depot of Supplies.
