Ground Military Occupational Specialties (MOS) cover a wide variety of roles, including Infantry Officers, Combat Engineers and Intelligence Officers. If you are assigned a Ground MOS, you will train at an MOS school to develop your particular expertise.

Programs last from 6 weeks to 24 months, depending on the level of technical proficiency. Most officers report to a designated Marine Corps MOS school, though some, such as Military Police Officers, attend a specialized school with their counterparts in other military branches.
