Stroke: a stroke occurs when there is a blocked (embolism) or ruptured (aneurysm/hemorrhage) blood vessel that supplies the brain, leading to severe and permanent damage to the tissues of the brain. A very severe stroke can cause brain death.
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.
While at the School of Infantry, Marines with a Military Occupational Specialty or MOS, in the Infantry field are trained at the Infantry Training Battalion (ITB). All other Marines receive their training in the basic infantry skills at the Marine Combat Training Battalion (MCT Bn). Going through the School of Infantry takes entry-level Marines and gives them enough training to become combat ready. In the Infantry Training Battalion, or ITB, Marines that have come out of Boot Camp are given a 59-day training course that provides teaching to Marines to learn how to deal with combat situations.
