Confidence is Key

U.S. Marine Corps Staff Sgt. Esmeralda Tumashev, a Senior Drill Instructor with Bravo Company, 1st Recruit Training Battalion, talks about the Confidence Course on Marine Corps Recruit Depot Parris Island, S.C.
The purpose of the Confidence Course is to get recruits out of their comfort zone, and establish a mindset to help them overcome obstacles in recruit training and in the Marine Corps.
