Marines earn their tan belt during basic training
MCMAP is a program developed by the Marine Corps that combines hand-to-hand and close quarter combat techniques. It also includes instruction in mental and physical discipline to prepare them for a combat situation.
Recruits are taught these techniques as self-defense and also to instill a combat mindset through discipline.
Through these disciplines, the recruits learn about responsibility and how they can be in control of themselves if they were ever in a combat situation and in their everyday life.
