Short Professional Bio
Matt Larsen is a retired U.S. Army Ranger, former U.S. Marine, combatives instructor, military training-system developer, author, combat-psychology educator, and one of the most consequential figures in modern American military combatives.
He is widely known as the:
“Father of Modern Army Combatives.”
Larsen led the research-and-development effort that evolved into the Modern Army Combatives Program (MACP), authored the Army’s 2002 field manual FM 3-25.150, Combatives, founded the United States Army Combatives School, and developed an instructor-development model designed to make combatives training sustainable throughout Army units rather than dependent upon a small number of specialists.
His influence therefore extends substantially beyond developing individual fighting techniques.
Larsen helped change the Army’s underlying model of close-combat training from:
short-term exposure to a fixed collection of techniques
toward
progressive skill development using live resistance, competition, instructor development, and unit-level training systems.
That distinction is central to understanding his contribution.
Larsen’s military career spanned approximately 22 years and included service in both the:
- United States Marine Corps,
- and United States Army.
Much of his Army career was associated with the 75th Ranger Regiment.
His operational experience included Ranger service during Operation Just Cause in Panama and the Gulf War.
By the mid-1990s, Larsen was serving in 2nd Battalion, 75th Ranger Regiment, where then-battalion commander Lt. Col. Stanley McChrystal tasked him with helping rebuild the unit’s practical hand-to-hand combat capability.
Larsen and other Rangers began evaluating martial arts and training methods according to a simple but important criterion:
Could they work against a fully resisting opponent?
That empirical approach became one of the foundational characteristics of Modern Army Combatives.
Brazilian Jiu-Jitsu became an important component, but Larsen did not simply convert Army hand-to-hand training into Brazilian Jiu-Jitsu.
The developing program incorporated useful elements from:
- Brazilian Jiu-Jitsu,
- wrestling,
- boxing,
- Muay Thai,
- judo,
- and other combat disciplines,
while continually evaluating them against military requirements.
The larger innovation was methodological.
Larsen emphasized:
live training
↓
resistance
↓
feedback
↓
adaptation
↓
progressive competence.
He subsequently carried those concepts from the Ranger Regiment into broader Army training.
At Fort Benning, Larsen helped establish what became the United States Army Combatives School.
In 2002, his work was institutionalized with publication of:
FM 3-25.150 — Combatives.
He later developed a multi-level train-the-trainer system so trained soldiers could establish and sustain combatives programs within their own units.
This created a multiplier effect:
Larsen
↓
Army Combatives School
↓
instructors
↓
unit programs
↓
soldiers
↓
future instructors.
That institutional architecture may ultimately be more important than any particular fighting technique Larsen introduced.
Modern Army Combatives became a recognized part of Army training, and Larsen’s influence extended into other military and government organizations.
His later professional work has included the development or consultation of combatives systems for American and allied military organizations and specialized government units.
Since 2017, Larsen has been associated with the United States Military Academy at West Point, serving as an instructor and course director/director in its combatives program.
His academic and professional interests have also expanded beyond physical fighting skills.
Larsen earned an M.A. in Combat Psychology from Adler University, with research interests including:
- combat psychology,
- stress,
- moral injury,
- psychomotor learning,
- warrior development,
- resilience,
- and behavioral preparation for violence.
This progression reveals the deeper theme in Larsen’s work.
He increasingly describes combatives not primarily as a collection of:
- punches,
- throws,
- takedowns,
- chokes,
- or grappling techniques,
but as a method of developing people who can continue functioning while facing:
resistance, uncertainty, aggression, fear, exhaustion, and failure.
Larsen is also a recurring contributor to Primary & Secondary.
Notable P&S discussions include:
P&S ModCast 192 — Evolutionary Combat Psychology
with Larsen participating in a discussion of combat mindset and the real-world psychological effects of violence.
P&S ModCast 411 — Airing of Grievances 2024
where Larsen joined a broader P&S professional panel.
And:
P&S ModCast 420 — Mitigating Moral Injury
in which Larsen led a discussion with Matt Landfair and Chuck Pressburg examining moral and physiological responses to critical experiences and their potential long-term effects.
Within the extended Primary & Secondary professional network, Larsen therefore represents an important bridge between:
close combat
↓
training methodology
↓
combat psychology
↓
human performance
↓
institutional culture.
A concise description of his contribution is:
Matt Larsen is the principal architect of the Modern Army Combatives movement whose most important contribution was not the creation of a particular martial art, but the development of a scalable training system built around live resistance, progressive learning, instructor development, competition, psychological preparation, and the cultivation of soldiers willing and able to continue functioning in close combat.

Long-Form Professional Profile
The Central Contribution
Matt Larsen is often described as the Father of Modern Army Combatives.
The description is appropriate, but it can also obscure what made his contribution important.
Larsen did not simply assemble a better collection of hand-to-hand fighting techniques.
His more significant achievement was helping change the training system.
The distinction is:
technique
versus
methodology.
A technique answers:
What should I do?
A methodology asks:
How do we reliably create people who can actually do it against resistance?
Larsen concentrated increasingly on the second question.
The Problem With Traditional Military Combatives
Military organizations have repeatedly attempted to teach hand-to-hand combat.
Historically, many programs followed a predictable structure:
select several techniques
↓
teach them during a short course
↓
test familiarity
↓
move to the next training requirement.
The soldier might technically have received combatives training.
But exposure is not competence.
Terminal Training
The weakness is what Larsen and the Army Combatives community later described as a type of:
terminal training.
The student learns a finite curriculum but receives no effective developmental pathway afterward.
Without:
- resistance,
- continuing practice,
- progression,
- coaching,
- competition,
- and increasingly difficult problems,
skill deteriorates.
The Alternative
Larsen’s emerging model was different.
Instead of trying to identify a handful of supposedly perfect combat techniques, the program needed to create:
fighters who could continue learning.
The model becomes:
foundation
↓
live practice
↓
resistance
↓
feedback
↓
adaptation
↓
higher-level training.
That is fundamentally different from memorizing techniques.
Marine Corps Foundation
Larsen began his military career in the United States Marine Corps.
His early military years coincided with extensive martial-arts exploration.
While stationed in Asia, he trained and competed in several combat disciplines.
This gave Larsen exposure to different answers to the same basic question:
How do humans actually fight?
More importantly, he began experiencing different ways of training people to fight.
Army Ranger
After the Marine Corps, Larsen entered the Army and ultimately joined the 75th Ranger Regiment.
He would spend a substantial portion of his Army career in the Ranger community.
His service included participation in:
Operation Just Cause
in Panama
and Ranger operations associated with the:
Gulf War.
The Ranger environment gave Larsen something different from conventional martial arts:
a military requirement.
Fighting Is Not Sport
A soldier’s problem is not winning a grappling tournament.
Nor is it winning a boxing match.
The battlefield involves:
- weapons,
- equipment,
- teammates,
- multiple opponents,
- terrain,
- fatigue,
- mission requirements,
- lethal force,
- and tactical objectives.
Therefore, no combat sport could simply be copied wholesale.
2nd Ranger Battalion
In 1995, while Larsen was a squad leader in 2nd Battalion, 75th Ranger Regiment, battalion commander Lt. Col. Stanley McChrystal tasked him with helping rebuild a practical combatives capability.
A group of Rangers began exploring different martial arts systems.
The key development was that ideas were not accepted merely because they were traditional or theoretically convincing.
They were tested.
Resistance as Quality Control
The developing group increasingly recognized that techniques had to survive:
live resistance.
This became a form of quality control.
If a technique works only while the training partner cooperates, its value is questionable.
If it repeatedly works against someone actively trying to stop it, confidence increases.
The methodology becomes:
claim
↓
resistance
↓
failure or success
↓
adaptation.
Brazilian Jiu-Jitsu
Brazilian Jiu-Jitsu became particularly influential because it provided a mature training culture based around:
full resistance.
Participants could grapple intensely while controlling the likelihood of catastrophic injury.
That characteristic was critical.
The important lesson was not:
Brazilian Jiu-Jitsu contains every answer.
It was:
live training produces honest feedback.
Royce Gracie and the Rangers
Members of the Ranger organization trained with members of the Gracie family, including Royce Gracie.
The effectiveness of their grappling methods against resisting opponents was difficult to dismiss.
BJJ consequently became an important foundation for the developing combatives system.
But it remained a foundation.
Filling the Gaps
Military fighting includes problems not addressed completely by sport grappling.
The program therefore incorporated methods from other disciplines.
These included:
- wrestling,
- boxing,
- Muay Thai,
- judo,
- and additional systems.
Each provided solutions for different ranges and problems.
Integrated Fighting
The emerging model was:
striking
clinch
takedowns
ground fighting
weapons
tactics.
The soldier needed enough integration that the boundaries between individual martial arts became less important than solving the problem.
No Sacred Technique
A major benefit of live training is that it discourages attachment to theory.
Techniques that repeatedly fail under resistance are exposed.
This creates an evolutionary process.
Technique
↓
test
↓
performance
↓
retain / modify / discard.
That framework is directly compatible with broader professional training culture.
Ranger Regiment to Army
As Rangers moved between assignments, combatives knowledge traveled with them.
Larsen eventually moved to the Ranger Training Brigade at Fort Benning.
There, his work expanded beyond one battalion or regiment.
The challenge became:
How do you scale the system across the Army?
FM 3-25.150
Larsen was tasked with rewriting Army combatives doctrine.
The result was published in 2002 as:
FM 3-25.150 — Combatives.
This represented an important institutional transition.
The program was no longer simply:
something Rangers were doing.
It had become:
Army doctrine.
Doctrine Creates Persistence
Institutionalization matters because individual instructors eventually leave.
Without documentation and structure, their knowledge may disappear.
Doctrine creates another pathway:
individual expertise
↓
written doctrine
↓
institution
↓
future practitioners.
United States Army Combatives School
Larsen subsequently established what became the:
United States Army Combatives School.
This was another critical step.
Doctrine provides information.
A school creates instructors.
Train-the-Trainer
Larsen later developed a multi-level instructor system.
This solved the scale problem.
One centralized school cannot personally train every soldier repeatedly.
Instead:
school
↓
instructors
↓
unit programs
↓
soldiers.
Those programs can then produce more experienced practitioners and future instructors.
Self-Sustaining Programs
The objective was not simply certification.
The desired outcome was:
self-sustaining combatives capability within units.
That is a sophisticated training-system objective.
The instructor is not merely taught techniques.
The instructor must learn how to:
- organize training,
- coach students,
- create progression,
- manage resistance,
- develop scenarios,
- and maintain a unit program.
Multiplication
This produces a powerful multiplier.
If Larsen directly teaches thirty soldiers, his direct influence is thirty.
If he teaches thirty instructors and each subsequently trains hundreds of soldiers, the scale changes dramatically.
This is:
instructor development as force multiplication.
Army-Wide Influence
Modern Army Combatives eventually spread throughout the Army.
Army publications describe it becoming part of initial-entry training and broader soldier-development requirements.
Its effects consequently reached a population far larger than any commercial martial-arts school could reasonably train directly.
Competition
Competition became another important component.
Competition creates:
- pressure,
- uncertainty,
- resistance,
- emotional investment,
- and an objective result.
It also exposes organizational competence.
Competition as Feedback
A useful training competition does more than identify a winner.
It reveals:
- weaknesses,
- strengths,
- bad habits,
- successful methods,
- coaching quality,
- and preparation quality.
The competition therefore becomes:
assessment.
Rules Shape Behavior
Larsen’s later writing emphasizes another sophisticated point:
competition selects for what its rules reward.
If a ruleset rewards one behavior, practitioners adapt toward that behavior.
Therefore:
rules
↓
incentives
↓
training behavior
↓
skill development.
This has implications well beyond combatives.
Training Design
Every training system implicitly rewards something.
If qualification rewards:
minimum performance,
students may train toward the minimum.
If competition rewards:
speed without tactical context,
students may optimize around speed.
Training designers therefore need to ask:
What behavior does this system actually produce?
Larsen’s work increasingly addresses this level of training design.
Warrior Ethos
Larsen has consistently argued that combatives serves a purpose beyond physical fighting skill.
One of the Army’s recurring descriptions of the program is development of the willingness to:
close with the enemy.
This is psychological.
The Willingness to Fight
A soldier can possess:
- weapons,
- fitness,
- technical knowledge,
- and equipment
but still fail if psychologically incapable of acting when violence becomes immediate.
Combatives creates a controlled environment where people experience:
- confrontation,
- aggression,
- fatigue,
- physical pressure,
- dominance,
- failure,
- and recovery.
Stress Exposure
The repeated cycle becomes:
stress
↓
action
↓
feedback
↓
adaptation
↓
confidence.
This resembles stress inoculation.
The goal is not eliminating stress.
It is improving function while stressed.
West Point
Since 2017, Larsen has worked in combatives education at the United States Military Academy at West Point.
That role provides an especially important downstream influence.
West Point trains future Army officers.
The model therefore becomes:
combatives training
↓
cadet
↓
officer
↓
unit leader
↓
organizational culture.
Officer Development
At West Point, combatives is not treated solely as physical education.
Recent Military Review research examining cadets’ perceptions of hand-to-hand combatives instruction places the activity within broader officer development.
Combatives can expose students to:
- adversity,
- immediate feedback,
- emotional regulation,
- controlled aggression,
- persistence,
- and leadership.
Combat Psychology
Larsen’s professional work has increasingly expanded into combat psychology.
He earned a:
Master of Arts in Combat Psychology from Adler University.
His research interests include:
- combat psychology,
- moral injury,
- human response to violence,
- psychomotor learning,
- and warrior development.
From Fighting to Human Behavior
This represents a logical evolution.
The early question was:
How do we teach soldiers to fight?
The deeper question becomes:
What allows a human being to function effectively during violence?
That includes physical skill.
But it also includes:
- perception,
- fear,
- decision-making,
- emotion,
- identity,
- moral framework,
- habituation,
- and stress response.
Psychomotor Learning
One of Larsen’s recurring interests involves how physical skills actually become usable.
Watching a demonstration creates information.
Information is not skill.
The progression requires:
understanding
↓
repetition
↓
feedback
↓
resistance
↓
automaticity
↓
contextual application.
This helps explain why many apparently impressive martial-arts demonstrations do not translate well into actual fighting.
Moral Injury
Larsen’s recent work on moral injury broadens the subject further.
Professionals exposed to violence may confront not merely fear or physical danger but experiences that collide with deeply held moral frameworks.
The effects may involve:
- guilt,
- shame,
- anger,
- betrayal,
- confusion,
- and identity disruption.
Understanding those reactions matters for military personnel, law enforcement, and others exposed to consequential violence.
Primary & Secondary
Larsen’s relationship with Primary & Secondary is particularly useful because his participation extends beyond an introductory combatives discussion.
He has contributed to P&S discussions involving:
- combat psychology,
- professional culture,
- moral injury,
- training,
- and human performance.
P&S ModCast 192 — Evolutionary Combat Psychology
In 2019, Larsen joined P&S for:
P&S ModCast 192 — Evolutionary Combat Psychology.
The panel examined combat mindset and real-world psychological effects.
This reflects Larsen’s transition from discussing merely:
how people fight
toward:
why people behave as they do during violence.
P&S ModCast 411
Larsen later participated in:
P&S ModCast 411 — Airing of Grievances 2024
alongside a broad panel of P&S contributors including Chuck Pressburg and John Valentine.
P&S ModCast 420 — Mitigating Moral Injury
In 2025, Larsen led:
P&S ModCast 420 — Mitigating Moral Injury
with:
- Matt Landfair,
- and Chuck Pressburg.
The discussion examined moral and physiological responses to stressful and violent experiences and their potential health effects.
This represents an important expansion of the P&S professional knowledge base.
John Valentine
Larsen’s downstream influence is also visible through instructors associated with him.
John Valentine, another member of the broader P&S professional network, has trained extensively under Larsen and is identified as a Modern Army Combatives black belt under him.
This provides a direct example of professional lineage:
Matt Larsen
↓
John Valentine
↓
military / professional instruction
↓
broader training community.
Combatives University
Larsen’s current work also includes:
Combatives University.
The concept extends his earlier training philosophy beyond a short seminar model.
Combatives University presents development as a long-term process encompassing more than grappling.
Its framework includes competencies involving:
- fighting,
- firearms,
- physical conditioning,
- trauma medicine,
- and other warrior skills.
Whether an individual follows that exact framework or not, the underlying philosophy remains consistent with Larsen’s earlier Army work:
competence requires sustained development.
Beyond Technique Collection
This is perhaps Larsen’s most important intellectual contribution.
People often approach training as collectors.
They collect:
- techniques,
- certifications,
- courses,
- equipment,
- and terminology.
Larsen’s model instead emphasizes:
capability.
The question is not:
What have you been shown?
It is:
What can you actually do?
Professional Assessment
Matt Larsen’s influence is unusually large because it occurred at the level of:
training architecture.
His contribution should not be reduced to:
bringing Brazilian Jiu-Jitsu into the Army.
That description is incomplete.
BJJ was important.
But the larger contribution was recognizing what made it effective as a learning environment:
people could train against genuine resistance.
Larsen then used that insight to help develop a broader combat-training methodology.
The sequence was:
identify failure of traditional training
↓
experiment with alternatives
↓
test them against resistance
↓
retain useful methods
↓
integrate multiple disciplines
↓
write doctrine
↓
establish school
↓
develop instructors
↓
create self-sustaining unit programs
↓
institutionalize capability.
That is a much more consequential achievement than selecting individual techniques.
It explains why Larsen’s influence persisted.
The Army did not merely inherit his personal fighting style.
It inherited a mechanism for continuing to produce fighters and instructors after Larsen himself moved on.
This is institutional knowledge transfer at scale.
His subsequent work at West Point and in combat psychology further demonstrates that his interest was never ultimately limited to martial arts.
The deeper problem is:
human performance during violence.
Combatives provides a laboratory for studying that problem.
Under resistance, students encounter:
- fear,
- fatigue,
- uncertainty,
- physical pressure,
- failure,
- dominance,
- aggression,
- and the need to continue acting.
That makes combatives simultaneously:
physical training
and
behavioral training.
Larsen’s later work concerning warrior culture and moral injury logically extends this framework.
The professional trajectory becomes:
How do people fight?
↓
How do people learn to fight?
↓
How do organizations create fighters?
↓
How does stress change behavior?
↓
How do experiences of violence affect identity and morality?
That progression makes Larsen particularly relevant to Primary & Secondary.
His work intersects:
- tactics,
- firearms,
- combatives,
- human performance,
- psychology,
- instructor development,
- institutional knowledge,
- and professional culture.
His downstream influence can also be demonstrated more clearly than that of many individual instructors.
The pathway is:
Matt Larsen
↓
75th Ranger Regiment combatives development
↓
FM 3-25.150
↓
United States Army Combatives School
↓
Army instructor cadre
↓
unit-level programs
↓
Army-wide soldiers
↓
future instructors and leaders.
And later:
Matt Larsen
↓
West Point
↓
cadets
↓
Army officers
↓
future units.
Few individual instructors have had an opportunity to influence professional training at that scale.
The strongest conceptual description is:
Matt Larsen is the principal architect of the Modern Army Combatives movement whose enduring contribution was transforming military close-combat training from short-term technique instruction into a scalable system of live resistance, progressive skill development, competition, instructor education and self-sustaining unit programs—and whose later work in combat psychology, moral injury and officer development has extended that same inquiry into the broader question of how humans and organizations prepare psychologically and physically for violence.
