The mission of Officer Candidates School (OCS) is to educate and train officer candidates in Marine Corps knowledge and skills within a controlled and challenging environment in order to evaluate and screen individuals for the leadership, moral, mental, and physical qualities required for commissioning as a Marine Corps officer.
TBS: The Basic School
The purpose of TBS is to train and educate newly commissioned or appointed officers in the high standards of professional knowledge, esprit-de-corps, and leadership required to prepare them for duty as company grade officers in the operating forces, with particular emphasis on the duties, responsibilities and warfighting skills required of a rifle platoon commander.
MOS: Military Occupational Specialty
Officer Candidates have MOS options specific to officers. Officer Candidate School (OCS) and The Basic School (TBS) are also specific to officers as compared to enlisted who attend Recruit Training, also known as boot camp.
