Matt Larsen is a former United States Marine, United States Army Ranger and Black Belt Magazine Hall of Fame combatives instructor. He is known as "The Father of Modern Combatives", credited with the creation of the United States Army's modern combatives doctrine and the establishment of the U.S. Army Combatives School. Larsen is also a Evolutionary Psychologist specializing in Combat Psychology, and is currently the Director of Combatives at the United States Military Academy at West Point.
Larsen enlisted in the United States Marine Corps as an infantryman in 1984. He was stationed overseas in Kanagawa Prefecture, Japan with the Marine detachment at Naval Air Facility Atsugi. During this time Larsen began training in judo, Shotokan karate, and traditional boxing. He continued his training in martial arts when he was transferred to Okinawa with the 3rd Battalion 5th Marine Regiment. He trained in Shōbayashi Shōrin-ryū with Eizo Shimabukuro and continued his judo training. He also trained Sayoc Kali in the Philippines. During this time Larsen fought in the Japan Karate Association's All Japan Karate Championships, Muay Thai bouts in Thailand, and a bare-knuckle fight against the ROK Marines Taekwondo champion. He was also a member of the 3rd Marine Division's boxing team.
Upon his discharge from the Marine Corps, Larsen enlisted in the United States Army. He went on to join the 75th Ranger Regiment, where he would remain for the next 14 years. Initially assigned to 1st Ranger Battalion at Hunter Army Airfield, Larsen parachuted into Panama with the Rangers during Operation Just Cause and was also involved in Ranger operations during the Gulf War. He began to involve himself more in combat sports and served as the president of the 1st Ranger Battalion's practical shooting club. Upon his reassignment to the 2nd Ranger Battalion, he started the Battalion's practical shooting club. He soon found himself as the Non-Commissioned Officer in Charge of combatives and Close Quarters Battle (CQB) training for the battalion. He utilized his martial arts training, having attained black belts in several disciplines including Brazilian Jiu-jitsu under Romero "Jacare" Cavalcanti and Russian Sambo, and merged them into a single, effective fighting style. As the program grew more elaborate, he became the NCOIC of combatives and CQB training for the entire 75th Ranger Regiment. During his service with the Rangers, he established himself as the Army's subject matter expert on combatives. When the opportunity to shape the Army's Combatives program came, he transferred to the Ranger Training Brigade, which was charged with the development of the combatives doctrine. During this time, he refined his training methods and started to compile a comprehensive training manual.
Larsen was asked to move to the 11th Infantry Regiment to design a combatives instructor training course for their cadre. As the 11th Infantry Regiment would soon have a more rigorous training regimen, taught by the Army's subject matter expert on combatives, the proponency for combatives doctrine moved with him. His ideas were well received by the 11th Infantry Regiment and he found himself with an old warehouse that he utilized as a combatives training facility. Within a short time, the school became so successful that units from throughout the Army began sending their soldiers. Several new courses had to be developed in order to continue teaching beyond the initial course, with the idea of building programs within these units. Eventually the school was recognized by the Army as the "United States Army Combatives School". In 2002, the training manual which he had been working on since his time with the Ranger Training Brigade was published by the Army as Field Manual 3–25.150 (Combatives).
