MCT: Marine Combat Training. All non-infantry Marines, upon completion of recruit training, will undergo Marine Combat Training (MCT). MCT consists of 29 days of battle skills training that enables Marines, regardless of MOS, to operate in a combat environment.
Non-infantry Marines will attend a course called Marine Combat Training for 29 days, then proceed to the appropriate school for their Military Occupational Specialty (which vary in length). Infantry Marines attend the Infantry Training Battalion for 59 days.
