During the war, Northwestern trained 49,725 military personnel through eleven training programs. The existing NROTC program proved to be a boon to the university as the War Department and Navy used Northwestern facilities to train 36,124 sailors over the course of the war, leading Northwestern to be called the "Annapolis of the Midwest." The programs included the Navy V-7 Naval Reserve Midshipman's School, V-5 Naval Aviation Preparatory Program, V-1 Accredited College Program, H-V(P) Medical and Dental Program, the V-12 Navy College Training Program, and training schools for cooks, bakers, and radio operators. The scale and importance of these programs led the Navy to cordon off the Lunt Building, Swift Hall, and Shanley Pavilion as well as taking over the dormitories and fraternities on the north campus. The Technological Institute housed training programs for the Radio School and V-12 Unit. The Army also established a signal corps training school on the Evanston campus and a civil affairs training school on the Chicago campus.
