The Basic School Quantico, Va.

About this Unit

The Basic School (TBS), located in Quantico, Virginia, was established in 1891 as the School of Application to provide newly commissioned Marine Corps officers with essential leadership and warfighting skills. Over the years, TBS has evolved into the cornerstone of Marine officer training, emphasizing small unit tactics, leadership, and the ethos of "every Marine a rifleman." During World War II, TBS expanded rapidly to meet the demands for trained officers, playing a critical role in preparing leaders for combat across the globe. Today, TBS continues its mission of shaping Marine officers, instilling the core values and tactical proficiency required for service in the Fleet Marine Force.
