Basic Overview The Marine OCS program (or Officer Candidate School) allows a man or woman in college pursuing an undergraduate degree to graduate after school with not only a diploma but also as an officer in the military. OCS involves several weeks over three summers of intensive military and officer training. During the school year, the candidate must attend mandatory training at a camp for three days, usually Friday to Sunday, once a month. In addition to the skills one learns during training, the candidate also gets paid during this period.
