Marine Officer Candidates earn their commissions after graduating from college and completing a program such as Platoon Leaders Class or Officer Candidate Course. They then attend The Basic School, followed by specialized training that prepares them for their Military Occupational Specialty (MOS). Officers serve in the operating forces, leading Marines in their primary MOS. After their first tour, they serve in non-MOS-related positions such as recruiting duty. Officers also attend career-level schools like Expeditionary Warfare School and may seek advanced degrees.
Promotions are based on time in rank, successful performance in assignments, and appropriate education. During active service, officers and their families have access to a wide range of personal and professional resources such as healthcare, travel, advanced education, and financial benefits. Above all, they are part of the Marine Corps family, and this camaraderie, as well as their leadership training and experience leading Marines, lasts a lifetime.
