The mission of the Recruit Depot and the Western Recruiting Region is to exercise operational control of enlisted recruiting operations in the 8th, 9th, and 12th Marine Corps Recruiting Districts; to provide reception, processing, and recruit training for enlisted personnel following initial entry into the United States Marine Corps; and to produce a basically trained United States Marine embodied with the fighting spirit, core values and esprit de corps which have ensured our Corps' success for over 240 years.
The unique relationship between the Marine Corps Recruit Depot and San Diego is the result of almost 150 years of mutual support, assistance and growth. This relationship is reflected in the history of the Marine Corps in San Diego, the Depot as a post of the Corps, and the heritage of San Diego itself.
The Depot's primary function is to take quality young men and women from the western two-thirds of the United States and transform them through the foundations of rigorous basic training, our shared legacy, and a commitment to our Core Values, preparing them to win our Nation's battles in service to the country.
The Depot is also home to Drill Instructor School which teaches Sergeants, Staff Sergeants and Gunnery Sergeants what it takes to make Basic Marines; and Recruiters School which teaches noncommissioned officers and Staff NCO's how to find America's best and brightest and bring them into our ranks.
