The School of Infantry's training mission ensures "Every Marine is, first and foremost, a Rifleman". At SOI, Marines with the Military Occupational Specialty of infantry (0300 occupational field) are trained at the Infantry Training Battalion (ITB), while all non-infantry Marines are trained in basic infantry/combat skills at the Marine Combat Training Battalion (MCT Bn). SOI marks a transition in the professional training of entry-level students from basically trained Marines to combat ready Marines.
Marine Corps Base Camp Lejeune is home to more than 43,000 Marines and Sailors from around the world. These servicemen and women serve with hundreds of company-size units that compose several major commands aboard base.

Marine motor detachment, New River Barracks, 1942
In April 1941, construction was approved on an 11,000-acre (45 km2) tract in Onslow County, North Carolina. On May 1 of that year, Lt. Col. William P. T. Hill began construction on Marine Barracks New River. The first base headquarters was in a summer cottage on Montford Point, and then moved to Hadnot Point in 1942. Later that year it was renamed in honor of the 13th Commandant of the Marine Corps, John A. Lejeune.
One of the satellite facilities of Camp Lejeune served for a while as a third boot camp for the Marines, in addition to Parris Island and San Diego. That facility, Montford Point, was established after Franklin D. Roosevelt signed Executive Order 8802. Between 1942 and 1949, a brief era of segregated training for black Marines, the camp at Montford Point trained 20,000 African-Americans. After the military was ordered to fully integrate, Montford Point was renamed Camp Gilbert H. Johnson and became the home of the Marine Corps Combat Service Support Schools.
