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.
All Marine recruits start their training at the Marine Corps Recruit Depot (MCRD). This is where America's young men and women are transformed into Marines. Some believe that Marines are forged in a furnace of shared hardship and tough training.
