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.
Initial training consists of Marine Recruit Training, and the School of Infantry which is the standard training where EVERY Marine learns to be a rifleman. Recently, changes in recruiting have enabled young recruits with little experience to attend the RECON Indoctrination Program (RIP).
