Marines attending the Marine Corps Instructor of Water Survival (MCIWS) Course on Marine Corps Recruit Depot Parris Island, S.C. endured various events together during the five-week training course before graduating June 25, 2021. The course is designed to teach and train Marines through events such as casualty rescues, distance swims, practical application and underwater endurance exercises designed to reduce fear, raise self-confidence, and develop Marines with the ability to survive in any situation in the water. 



Aboard the depot, the role of a MCIWS is to train recruits in basic swim qualification and develop their confidence in the water.
