Marines on the Yard

Marine Detachment (MARDET)

Sampson Hall · Marine Detachment offices

The USNA Marine Detachment runs the Marine Corps engagement program: informing, influencing, assessing, selecting, and equipping midshipmen for commissioning as Marine officers. MARDET staff coordinate summer training (Leatherneck, MAGTF, PROTRAMID), selection, accessions, and detachment administration — nested within the Naval Academy mission to develop midshipmen morally, mentally, and physically.

Talk to MARDET if you need: selection guidance, summer training questions, or detachment-level policy.

Company Marine Mentors

Bancroft Hall · Across all 36 companies

Each of the Brigade's 36 companies has a dedicated Marine officer mentor. Mentors live and work alongside midshipmen — informing and influencing them at the individual level, preparing interested mids for Leatherneck, and supporting career conversations throughout four years at the Academy.

Talk to your mentor if you need: company-level guidance, PROTRAMID/Leatherneck prep, or an MOS conversation.

Company Officers (Marine)

Bancroft Hall · Commandant's Department

Marine officers serve as company officers within the Commandant's Department, leading midshipman companies day-to-day alongside Navy company officers. They are responsible for the professional development, accountability, and welfare of mids in their company — distinct from the mentor role, though some Marines may serve in related leadership billets.

Talk to your company officer if you need: disciplinary, administrative, or company leadership matters.

Academic Instructors

Academic buildings across the Yard

Marine officers and staff serve as instructors in academic departments — including the School of Humanities and Social Sciences, engineering, and other divisions. They teach courses, advise midshipmen academically, and model the scholar-warrior ethos.

Talk to an instructor if you need: academic mentorship in their department or perspective on teaching billets.

Athletics & Extracurricular Coaches

Fields, gyms, and club spaces across the Yard

Marines coach club sports, combatives, and other extracurricular programs. These officers build character and resilience outside the classroom — often the Marine you meet at practice is not your company mentor but still a valuable resource.

Talk to a coach if you need: athletics-related mentorship or Marine perspective through your sport or club.

Commandant's Staff & Support Billets

Commandant's Office · Various Yard locations

Additional Marines serve on the Commandant's staff, in support roles, and in specialized billets (LEAD program, ethics and leadership, etc.). They contribute to brigade-wide programs and midshipman development beyond a single company.

Talk to these Marines if you need: guidance on a specific program they run — or ask your mentor to point you to the right person.
