In 2001, the Marine Corps initiated an internally designed martial arts program, called Marine Corps Martial Arts Program (MCMAP). Because of an expectation that urban and police-type [[peacekeeping]] missions would become more common in the 21st century, placing marines in even closer contact with unarmed civilians, MCMAP was implemented to provide marines with a larger and more versatile set of less-than-lethal options for controlling hostile, unarmed individuals. It is a stated aim of the program to instill and maintain the "Warrior Ethos" within marines.<ref name="Yi">Yi, Capt. Jamison, USMC. "MCMAP and the Warrior Ethos", ''Military Review'', November–December 2004.</ref> The MCMAP is an eclectic mix of different styles of martial arts melded together. MCMAP consists of punches and kicks from [[Taekwondo]] and [[Karate]], opponent weight transfer from [[Jujutsu|Jujitsu]], ground grappling involving [[joint lock]]ing techniques and [[chokehold|chokes]] from [[Brazilian jiu-jitsu]], and a mix of knife and baton/stick fighting derived from [[Arnis|Eskrima]], and elbow strikes and kick boxing from [[Muay Thai]]. Marines begin MCMAP training in boot camp, where they will earn the first of five available [[Marine Corps Martial Arts Program#Structure and belt system|belts]]. The belts begin at tan and progress to black and are worn with standard utility uniforms.<ref>{{Cite journal |title=The Few and the Proud: A Tradition of Excellence Fuels the US Marine Corps Martial Arts Program |first=Loren |last=Franck |journal=Black Belt |year=2003 |page=70 |volume=41 |issue=7}}</ref>
