Matt Larsen

The Army Ranger who built the U.S. Army's modern combatives program on Gracie jiu-jitsu, a black belt under Jacaré who now directs combatives at West Point.

Biography

Matt Larsen is the Army Ranger who chose Brazilian jiu-jitsu as the starting point for the U.S. Army's modern hand-to-hand combat training. Handed the job of reviving close-quarters fighting in his Ranger battalion in 1995, he built what grew into the Modern Army Combatives Program, and he is often called its father. He holds a black belt in Brazilian jiu-jitsu from Romero "Jacaré" Cavalcanti and is the director of combatives at the U.S. Military Academy at West Point. Marines and Rangers Larsen came to the martial arts through the Marine Corps. By his own account on his gym's website, he started while serving as a young infantryman in Japan, first in Tokyo and then on Okinawa, and his travels took him to fights elsewhere in East Asia as well, in Korea, Thailand and the Philippines. A 2018 course biography lists where and in what he competed early in his career: Kodokan judo in both Tokyo and Okinawa, karate at the All Japan Karate Championship, taekwondo in Korea, kali in the Philippines, Muay Thai in Bangkok and boxing for the Marine Corps. He then left the Marines for the Army and served in the 75th Ranger Regiment for more than twelve years. Among the operations his website lists from that time are the parachute assault on the Torrijos-Tocumen airfield during the U.S. invasion of Panama and the Rangers' part in the Gulf War. West Point puts his time in uniform, across the Marines and the Rangers, at 22 years. The 1995 assignment In 1995 Larsen was a squad leader in the 2nd Battalion, 75th Ranger Regiment, when the battalion commander, Lt. Col. Stanley McChrystal, told him to bring back a hand-to-hand fighting method that would hold up in practice. A 2008 Army article treats that order as the beginning of the Modern Army Combatives Program. Larsen gathered soldiers who were already training in different martial arts off post, and together they tested how well each style worked. They also tried the Marine Corps Martial Arts Program handbook. The decision came on the advice of J. Robinson, a Vietnam-era Ranger who was head wrestling coach at the University of Minnesota: Larsen settled on the Brazilian jiu-jitsu taught by the Gracie family. Michael Robinson, a sergeant first class who was one of Larsen's early Rangers, later remembered that the first Gracie to teach the battalion was Royce Gracie. In his telling, Royce faced 30 of the battalion's soldiers one after another with no break, and only then showed them how he had done it. Robinson called that session the start of the battalion's combatives program. The written notes to a 2023 podcast interview with Larsen summarize the connection in a similar way, tying the arrival of jiu-jitsu in the Ranger Regiment to Royce Gracie's UFC success, which led to the Gracies being hired as instructors. The battalion's first test of the new training came at a Joint Readiness Training Center, where an impromptu combatives pit sprang up between the 1st and 2nd Ranger Battalions and a company from the 3rd. After roughly eight hours of matches, Robinson recalled, the 2nd Battalion had lost just three. From one battalion to the whole Army On his own account, Larsen became the NCO in charge of combatives for the 2nd Ranger Battalion and then, as the program spread, for the whole 75th Ranger Regiment, where he was also the regiment's master trainer in marksmanship and close-quarters battle. His next post was the Ranger Training Brigade at Fort Benning, Georgia, and his orders there were to take the program Army-wide. There he opened the "fight house" that became the home of the Modern Army Combatives Program, and he served as the program's NCO in charge. He also rewrote the Army's field manual on hand-to-hand fighting, FM 3-25.150 (Combatives). His version became official Army doctrine in 2002, and by his own account he revised it again in 2009. In 2010 the Army's training command described him as the program's creator and director, and said the manual was the reason he was often called its father. A further assignment took him to the 11th Infantry Regiment. There he developed a four-level course for training trainers, and the course came to carry the name United States Army Combatives School. West Point credits him with founding the school and serving as its commandant, and as director of the Army's combatives program, for more than a decade. Larsen retired from the Army in 2005, according to his website, and by mid-2008 he was running the program as a civilian. By then, an Army article reported, soldiers had to complete the training to get through initial entry training, and it was part of the Warrior Tasks, the list of skills every soldier is expected to know. What the courses taught As the Army described it in 2008, the program ran in four levels. Level I was a 40-hour, week-long introduction to about 20 basic jiu-jitsu techniques. It included a drill in which students had to close the distance and reach a clinch while an instructor threw punches at them. Level II took two weeks, covered about 50 techniques and prepared students to teach Level I. Levels III and IV lasted a month each, and Level IV was taught only at Fort Benning. In November 2009 Larsen said that more than 57,000 troops had graduated from the school: 50,374 at Level 1, 5,255 at Level 2, 1,408 at Level 3 and 564 at Level 4. Nine years later, introducing an interview with him, West Point's Modern War Institute wrote that almost anyone who had served in the Army over the previous fifteen years or more would have done the combatives training he helped create. In the same 2009 report, speaking as director of the school, Larsen described a revision of the curriculum built on lessons from Iraq and Afghanistan and on more than 900 interviews with soldiers who had fought hand to hand there. The goal was to bring advanced material, such as fighting for control of a weapon and using grappling principles on the feet inside small rooms, down to small units and basic training. Levels 1 and 2 became the basic and tactical combatives courses, and Levels 3 and 4 the basic and tactical instructor courses, with the training hours at each tier unchanged. The school, he said, would hold on to its four pillars of universal, foundational, motivational and tactical instruction. How he explained it In 2010 Larsen named two lessons behind that year's curriculum changes. The first was that "Every fight is grappling." The second was that on a battlefield no fight is truly unarmed, which is why fighting skills involving weapons were moved down into basic training. He also put hand-to-hand combat in proportion: in battle, he said, the winner is the soldier whose friend is first to arrive with a gun. The value of the training, as he saw it, lay in making better soldiers and leaders, and its real mission was to change the Army's culture so that warrior skills and attributes are valued. Soldiers take on values, he argued, from the demands training makes of them, not from memorizing slogans. To show that technique could beat size, he pointed to 1st Lt. Christine Van Fleet, the program's first female level 3 instructor, who at about 145 pounds choked out a 225-pound opponent 30 seconds into a match. He set out related ideas for West Point's Modern War Institute. In a 2017 list of five books that shaped his thinking about war, he singled out belonging to a unit as a source of effectiveness and resilience, wrote that training which leaves soldiers unready for the confusion and fear of real combat is wrong, and argued that the side able to keep its will to fight the longest is the one that wins. In December 2017 he spoke in the institute's speaker series under the title "How We Build Warriors Willing to Fight", and in a 2018 interview, according to the institute's introduction, he argued that a warrior ethos has to run through the whole Army, not only the infantry and the other combat arms. Black belt under Jacaré Larsen's own jiu-jitsu rank comes from Romero "Jacaré" Cavalcanti. The instructor biography on Cavalcanti's Alliance school website in Atlanta, as archived in 2010, lists Matt Larsen among the black belts Cavalcanti had graduated. A 2018 course biography says the same, and states that he holds black belts in several martial arts, Brazilian jiu-jitsu among them. Cavalcanti had received his own black belt from Rolls Gracie in 1982. The two men also worked together. The Alliance biography lists Cavalcanti as a consultant and instructor in hand-to-hand combat for the Army Rangers at Fort Benning, and says that Cavalcanti, working with Larsen, was chosen as main instructor by the Rangers there and by several law enforcement agencies. Beyond the Army After his military career Larsen worked as a security contractor. His website names Afghanistan and Iraq, and his West Point profile adds the Middle East and Africa, where he managed a security company in the continent's central and southern regions. By his own account he helped rework combatives instruction for the Canadian Special Operations Regiment, the U.S. Air Force and the Army's John F. Kennedy Special Warfare Center, and advised the British Army's infantry and the Royal Marine Commandos on their programs. West Point adds combatives consulting for, among others, the Kuwait Police Special Forces, the Polish Diplomatic Security Corps, and the armed forces and presidential guard of the United Arab Emirates. He also ran a gym under his own name, Matt Larsen's Combat Fitness Center, in Columbus, Georgia. The 2018 course biography credits him with the book Modern Army Combatives: Battle-Proven Techniques and Training Methods and with co-writing Sniper: American Single-Shot Warriors in Iraq and Afghanistan. According to his website, he has also served as editor of two survival and evasion titles published by Lyons Press. West Point Larsen works in West Point's Department of Physical Education as an instructor and combatives director, and the academy lists his education as an M.A. in combat psychology and a B.S. in natural science. Black Belt Magazine visited in 2022 and laid out the cadet program. As the magazine described it, the program opens with movement: running, climbing, falling, basic gymnastics and swimming under stress. It then works through boxing and ground fighting with strikes, and ends in a close-quarters class where weapons come in. Larsen told the magazine that the cadets, as future officers, will be responsible for keeping their soldiers fit and for working with the officers under them to hold the standard. He described learning as moving a skill from short-term into long-term memory, and compared it to learning letters, then words, and then putting together thoughts of one's own.
