Short Professional Bio
The late John Holschen (1958-2025) was a retired U.S. Army Special Forces veteran, weapons specialist, medic, combatives instructor, protective-security professional, firearms instructor, internationally experienced trainer, two-time National Tactical Invitational winner, and one of the more analytically sophisticated instructors in the modern defensive-training community.
Holschen served more than two decades in the U.S. Army Special Operations and Intelligence communities.
His documented military roles included service as a:
- U.S. Army Special Forces Weapons Sergeant,
- Special Forces Medic,
- instructor at the John F. Kennedy Special Warfare Center,
- Senior Hand-to-Hand Combat Instructor,
- and Master Instructor for 1st Special Forces Group.
His later operational experience included work in the Middle East and Pacific region as a:
- protective-security specialist,
- government-facility security manager,
- contractor,
- trainer,
- and operator.
After his military career, Holschen became closely associated with Greg Hamilton and InSights Training Center, where he became a senior instructor in firearms, tactics, combatives, personal defense, and instructor development.
His reputation was supported by unusually strong objective performance credentials.
Holschen was one of only two people identified by InSights as having won the National Tactical Invitational twice, and the American Tactical Shooters Association recognized him as both a:
Master Tactician
and
Master Instructor / Master Trainer.
Across nine National Tactical Invitational appearances, later biographies report that he consistently finished among the event’s top performers.
The NTI was especially relevant to Holschen’s philosophy because it evaluated substantially more than shooting.
Participants were confronted with problems involving:
- judgment,
- tactics,
- communication,
- physical skills,
- unknown contacts,
- force decisions,
- scenario recognition,
- and firearms performance.
That environment aligned closely with Holschen’s larger view of defensive preparation:
shooting is only one component of survival.
His civilian instruction integrated:
- handgun,
- rifle,
- low-light skills,
- close-quarter defense,
- edged-weapon defense,
- empty-hand combatives,
- movement,
- use of cover,
- decision-making,
- awareness,
- scenario analysis,
- and human performance.
He was also an experienced martial artist with decades of training and teaching across multiple systems.
Late in his career, Holschen moved increasingly toward cognitive science, visual processing, neuroscience, and decision-oriented firearms training.
Working with Dustin Salomon and the NURO Shooting System, he explored methods for forcing students to:
perceive
↓
identify
↓
process
↓
decide
↓
act
rather than merely respond to a known shooting command.
That work was featured directly in Primary & Secondary ModCast 371 — Integrating Visual Stimuli Into Training, where Holschen, Matt Landfair, and Dustin Salomon discussed the incorporation of visual information and cognitive processing into firearms instruction.
Holschen died unexpectedly of natural causes in September 2025.
His death was widely described by respected instructors including Tom Givens and Greg Ellifritz as a major loss to the professional training community.
His distinctive contribution was the progressive integration of:
operational experience
combatives
measured tactical performance
instructional methodology
cognitive science
into a more complete model of defensive capability.

Long-Form Professional Profile
A Complete Defensive Practitioner
John Holschen’s professional significance is difficult to capture if he is described only as:
a firearms instructor.
Firearms were one part of his work.
His larger subject was:
human performance during dangerous events.
His career combined:
- military special operations,
- medicine,
- weapons,
- martial arts,
- close combat,
- protective security,
- tactical decision-making,
- scenario evaluation,
- firearms,
- adult instruction,
- and eventually cognitive science.
That combination produced a training philosophy considerably broader than conventional marksmanship instruction.
Special Operations Background
Holschen served more than two decades within the United States Army’s Special Operations and Intelligence communities.
Public professional biographies identify him as both a:
Special Forces Weapons Sergeant
and
Special Forces Medic.
Those specialties develop different professional perspectives.
Weapons
A Special Forces weapons specialist must understand more than simply how to shoot.
The role traditionally requires expertise involving:
- weapon systems,
- employment,
- maintenance,
- instruction,
- foreign weapons,
- tactical application,
- and the ability to teach others.
Medicine
A Special Forces medical background develops another type of thinking.
Medical problems demand:
- assessment,
- prioritization,
- adaptation,
- uncertainty management,
- and decisions under time pressure.
The combination of:
weapons
and
medicine
is significant because each reinforces a problem-solving orientation rather than dependence upon one rigid technique.
Instructor Development
Holschen also taught at the John F. Kennedy Special Warfare Center.
He later served as the Senior Hand-to-Hand Combat Instructor and Master Instructor for 1st Special Forces Group.
These roles represent another professional transition:
operator
↓
experienced practitioner
↓
instructor
↓
instructor developer.
Teaching operators is different from merely possessing operational skill.
The instructor must identify:
what actually matters
and then create a method through which another person can reliably learn it.
Tacit Knowledge
Operational experts frequently possess substantial:
tacit knowledge.
They may recognize a problem almost immediately without consciously articulating every cue that produced the recognition.
That creates an instructional challenge.
Making Expertise Transferable
The instructor must convert:
intuition
into
observable principles.
The process becomes:
experience
↓
pattern recognition
↓
principle
↓
drill or exercise
↓
student experience
↓
feedback.
This became one of Holschen’s defining strengths.
Combatives
Holschen’s expertise extended deeply into:
hand-to-hand combat.
Older professional biographies document more than twenty years of martial-arts experience and significant instructional experience across systems including:
- Daito Ryu Aiki Budo,
- Shorin Ken Karate Do,
- and Shotokan Karate.
His military role further integrated combatives into operational training.
Firearm Is Not Always Available
This matters because personal defense does not always begin with:
gun already in hand.
A confrontation may begin:
- at conversational distance,
- during physical contact,
- during an attempted weapon grab,
- inside a confined space,
- or before lethal force is justified.
Continuum of Skills
A complete defensive practitioner therefore needs more than:
shooting.
The system can involve:
awareness
↓
avoidance
↓
communication
↓
positioning
↓
empty-hand skills
↓
weapon access
↓
firearms
↓
medical response.
The exact sequence varies.
The important point is that the firearm exists inside a larger defensive system.
InSights Training Center
Holschen became strongly associated with InSights Training Center, founded by Greg Hamilton.
InSights has taught private citizens, police officers, SWAT personnel, corrections personnel, security professionals, and military special-operations personnel since 1990.
Holschen became one of its most respected instructors.
Integrated Fighting System
InSights emphasized an integrated approach involving:
- mindset,
- tactics,
- strategy,
- technical skill,
- firearms,
- and combatives.
Student accounts consistently describe Holschen as unusually capable of breaking complex performance into understandable components.
Pedagogy
This is an important part of Holschen’s legacy.
Possessing expertise is one skill.
Teaching expertise is another.
Students repeatedly described him as:
- methodical,
- analytical,
- patient,
- technically demanding,
- and able to improve shooters across differing levels of existing ability.
Intensive Handgun Skills
One particularly well-documented example is the InSights Intensive Handgun Skills course.
The class emphasized:
- sight management,
- trigger control,
- accuracy,
- speed,
- economy of motion,
- long-range shooting,
- barricades,
- movement,
- moving targets,
- and performance under time pressure.
Deconstruction
Holschen described the process as effectively:
deconstructing shooting into its smallest components.
This is an important instructional principle.
Complex performance becomes easier to diagnose when separated into:
subskills.
Decomposition
The progression becomes:
complete shooting action
↓
vision
grip
presentation
trigger control
timing
movement
↓
diagnose component
↓
improve component
↓
reintegrate.
That is deliberate skill development.
Economy of Motion
His handgun curriculum emphasized:
economy of motion
and
economy of time.
The concept is not simply:
move faster.
The better objective is:
remove unnecessary movement.
Efficiency Before Speed
The relationship is:
better mechanics
↓
less wasted movement
↓
shorter execution time
↓
greater repeatability.
Speed becomes an outcome of efficiency.
National Tactical Invitational
Holschen’s performance at the National Tactical Invitational provides unusually strong external validation.
The NTI was not simply a shooting match.
It was designed to test defensive practitioners across multiple domains.
Two-Time Winner
InSights identifies Holschen and Greg Hamilton as the only:
two-time NTI winners.
Holschen was also recognized by the American Tactical Shooters Association as a:
Master Tactician
and
Master Trainer / Master Instructor.
Other professional biographies document repeated top placements over approximately nine appearances.
Why the NTI Matters
Traditional firearms competition can measure:
- accuracy,
- speed,
- movement,
- and technical execution.
The NTI added problems involving:
- tactics,
- decision-making,
- unknown contacts,
- scenario interpretation,
- physical interaction,
- and judgment.
Performance Across Domains
The question was not simply:
Can you shoot?
It was closer to:
Can you solve the problem?
That distinction strongly parallels Holschen’s later teaching philosophy.
Scenario-Based Evaluation
Scenario training exposes a different set of skills.
The participant must:
observe
↓
interpret
↓
decide
↓
act
↓
adapt.
The sequence begins before the trigger press.
Tactical Problem Solving
This is why a technically excellent shooter may still perform poorly in a scenario.
The shooting may be flawless.
The decision may be wrong.
The Complete Equation
Defensive performance can be represented as:
perception
orientation
decision
movement
communication
technical execution
=
outcome.
Holschen spent much of his career working across the complete equation.
Terrorism and Threat Analysis
Following military and overseas experience, Holschen also taught material involving terrorist tactics and emerging threats.
In the early 2000s he presented analysis of captured or publicly available terrorist training materials and discussed their implications for defensive preparation.
Operational Information → Civilian Relevance
Again, his method was not simply:
show interesting operational material.
The useful question was:
What does this mean for the person who may encounter the problem?
That requires translation.
Protective Security
Holschen later worked overseas in protective-security and government-facility security roles.
Contemporary sources describe tours in the Middle East as both:
- protective-security specialist,
- and site-security manager.
Tom Givens later described his contracting work as spanning the Middle East and Pacific Rim.
Equipment Evaluation
Operational deployment also exposed Holschen to equipment under sustained professional use.
One early example is his reporting on the EOTech holographic sight during overseas use.
His analysis emphasized actual performance:
- long daily operating periods,
- environmental exposure,
- impact,
- battery use,
- reliability,
- and zero retention.
Observation Over Fashion
His commentary is revealing because he explicitly dismissed much of the equipment discussion he encountered as:
personal preference.
Instead, he focused on:
whether the tool performed the required function.
That is a durable evaluation principle.
Requirement → Performance
The relevant chain becomes:
operational requirement
↓
equipment
↓
sustained use
↓
observed performance
↓
judgment.
Civilian Defensive Training
One of Holschen’s most significant achievements was translating highly specialized experience into training appropriate for:
ordinary citizens.
This required restraint.
Special Operations Is Not Civilian Self-Defense
Military tactics are not automatically appropriate for private citizens.
The contexts differ in:
- mission,
- legal authority,
- equipment,
- team structure,
- expected threats,
- logistics,
- and acceptable risk.
Translation, Not Replication
TacCon described Holschen’s civilian work as converting specialized skills from weapons and combatives into:
useful defensive curricula for private citizens.
That wording is important.
He was not merely giving civilians:
operator training.
He was adapting principles to their actual problem.
Context
The relevant question becomes:
What does this person need?
Not:
What did I do in Special Forces?
Civilian Problem
A private citizen’s defensive requirements may include:
- recognizing danger,
- avoiding unnecessary confrontation,
- managing unknown contacts,
- creating distance,
- accessing a concealed firearm,
- protecting family members,
- making legally defensible decisions,
- and stopping when the threat ends.
That is a different mission from offensive military operations.
Training for the Student’s Reality
The progression becomes:
operational principle
↓
identify transferable element
↓
remove mission-specific assumptions
↓
adapt to civilian context
↓
teach
↓
test.
This is professional curriculum design.
Teaching People to Think
Holschen repeatedly emphasized a larger problem:
students often want techniques when what they need is judgment.
Older National Tactical Invitational discussions involving Holschen addressed the difficulty of attracting students to classes designed to teach:
how to think
rather than merely:
how to shoot.
This theme became increasingly central later in his career.
Known Problems vs. Unknown Problems
Traditional range training usually provides the student with a known problem.
For example:
At the signal, fire two rounds.
The shooter already knows:
- a signal is coming,
- the firearm will be needed,
- the target is valid,
- shooting is expected.
The student’s main task is:
execution.
Real Events Are Different
An actual defensive event begins with uncertainty.
The person must first determine:
- Is this a threat?
- What is happening?
- Does action need to occur?
- Which action?
- Is lethal force justified?
- Has the situation changed?
The problem is therefore:
information processing before execution.
Perception
Holschen’s late-career work increasingly focused on:
perception.
Humans do not respond to reality directly.
They respond to:
what they perceive reality to be.
That distinction matters enormously in use-of-force events.
Visual Processing
The eyes collect information.
The brain must then:
- identify,
- classify,
- prioritize,
- and interpret
that information.
Only then can a useful decision occur.
The Old Range Model
Much conventional firearms training compresses this process into:
beep
↓
shoot.
That develops useful mechanics.
But it does not strongly exercise:
recognition and decision.
NURO
Late in his career, Holschen became an enthusiastic user and advocate of Dustin Salomon’s NURO Shooting System.
NURO uses programmable visual stimuli integrated with range exercises.
Instead of responding only to a conventional shot-timer beep, students may receive changing:
- colors,
- shapes,
- locations,
- and visual signals.
Perception → Decision → Action
The system allows instructors to create problems that require:
see
↓
interpret
↓
choose
↓
execute.
That adds cognitive demand before firearm manipulation.
Unknown Contact Management
In some Holschen exercises, different visual signals represented different behavioral requirements.
One stimulus might indicate:
shoot.
Another might require:
verbal management.
A combination might require:
weapon ready but not fired.
The student therefore cannot simply:
draw on the signal.
Response Inhibition
This develops another critical skill:
not shooting.
That may be just as important as rapid shooting.
Go / No-Go
The student must distinguish:
go
from
no-go
and potentially:
not yet.
That is decision training.
Cognitive Load
As complexity increases, the student must manage:
- visual information,
- firearm manipulation,
- movement,
- verbal commands,
- time pressure,
- and changing conditions.
This imposes:
cognitive load.
Automaticity
Well-developed mechanical skills reduce the cognitive resources required for basic gun handling.
That leaves more capacity for:
decision-making.
This produces a powerful relationship:
automatic technical skill
↓
lower mechanical cognitive demand
↓
more available attention
↓
better problem solving.
Neuroscience-Informed Training
Holschen’s later curriculum increasingly explored how:
- neural pathways,
- visual processing,
- reaction,
- perception,
- and movement
interact during stressful events.
This represented a substantial evolution from conventional firearms training.
Building the Brain, Not Just the Draw Stroke
Traditional firearms education often concentrates on:
motor patterns.
Holschen increasingly focused on connecting motor patterns to:
information processing.
The objective becomes:
appropriate action
rather than merely:
fast action.
Applied Defensive Handgun Skills
His later Applied Defensive Handgun Skills curriculum used NURO-based exercises to challenge students repeatedly with observed and critiqued problems.
Course descriptions emphasized:
- visual-system performance,
- tactically relevant information processing,
- movement,
- use of cover,
- verbal responses,
- firearm access,
- and realistic time constraints.
Repetition With Variation
The importance lies in combining:
repetition
with
variation.
Pure repetition can create an efficient motor program.
Variable repetition teaches:
adaptation.
Adaptive Skill
The progression becomes:
recognize pattern
↓
execute response
then:
pattern changes
↓
recognize change
↓
modify response.
That is closer to adaptive expertise.
P&S ModCast 371
Holschen’s late-career philosophy was directly documented within Primary & Secondary ModCast 371 — Integrating Visual Stimuli Into Training.
The panel consisted of:
- John Holschen
- Dustin Salomon
- Matt Landfair
and focused on effective instruction and the incorporation of visual stimuli into training.
This episode provides an especially strong connection between Holschen’s work and the Primary & Secondary knowledge network.
The Importance of Visual Stimuli
The discussion addresses a fundamental limitation in conventional firearms instruction.
If every repetition begins with:
known target + known response + auditory beep
then the student can become extremely proficient at:
that specific information-processing pathway.
But defensive encounters rarely announce themselves with a shot timer.
Training Architecture
A more complete curriculum can vary:
- stimulus,
- timing,
- location,
- required response,
- and available information.
That develops a different capability:
problem solving under uncertainty.
Instructor Development
This also changes the instructor’s job.
The instructor is no longer simply observing:
hits and time.
The instructor must evaluate:
- what the student perceived,
- what decision was made,
- whether it was appropriate,
- how quickly information was processed,
- and how technical performance interacted with judgment.
Outcome vs. Process
A student can produce:
a good hit
after making:
a bad decision.
If the instructor evaluates only the target, the training misses the error.
Training the Decision Cycle
Holschen’s later work therefore represented a progression from:
shooting instruction
toward
decision-cycle instruction.
That is a substantial conceptual shift.
Evolution Rather Than Dogma
Perhaps one of the most important characteristics of Holschen’s career was that his training continued to evolve.
He had:
- decades of military experience,
- elite instructional credentials,
- competitive tactical success,
- and longstanding professional recognition.
It would have been easy to simply continue teaching:
what had always worked.
Instead, he continued exploring new research and technology.
Expertise Should Update
The progression was:
experience
↓
expertise
↓
new evidence
↓
revision
↓
better model.
That is intellectual humility expressed through professional development.
Greg Ellifritz’s Assessment
After Holschen’s death, instructor Greg Ellifritz described him as one of the rare intellectuals in the firearms and self-defense training world.
Ellifritz specifically emphasized that Holschen remained on the cutting edge of developing innovative training methods.
That assessment is particularly meaningful because Ellifritz had followed Holschen’s work since the 1990s and later attended his classes.
Tom Givens’ Assessment
Tom Givens likewise described Holschen as a:
master trainer
and
innovator.
Givens specifically highlighted Holschen’s late-career use of modern technology to better prepare students for serious events.
Peer Recognition
This matters because professional reputation is strongest when supported by:
credible peers.
Holschen’s reputation was not based primarily on self-promotion.
It was repeatedly reinforced by experienced instructors and practitioners who:
- trained with him,
- competed with him,
- invited him to teach,
- or learned from him.
Quiet Professional
Holschen maintained a comparatively modest public presence relative to many modern training personalities.
His influence traveled strongly through:
professional networks.
This produced:
high trust
rather than necessarily:
high visibility.
Teacher of Teachers
The downstream effect can be seen in instructors who cite Holschen as:
- mentor,
- teacher,
- influence,
- or source.
That produces influence far beyond direct student count.
Multiplicative Knowledge Transfer
The pathway becomes:
John Holschen
↓
student
↓
future instructor
↓
hundreds of additional students.
That is multiplicative influence.
Institutional Knowledge
His legacy therefore exists partly in:
people.
Techniques change.
Technology changes.
Specific equipment changes.
But instructors influenced by his analytical method continue carrying forward:
- problem decomposition,
- contextual training,
- tactical judgment,
- integrated defensive skills,
- cognitive processing,
- and adaptive learning.
Professional Assessment
John Holschen was one of the more important integrative thinkers in modern defensive firearms and personal-protection training.
His significance cannot be reduced to his impressive résumé.
The larger progression is:
Special Forces operator
↓
weapons specialist / medic
↓
combatives instructor
↓
master instructor
↓
protective-security practitioner
↓
civilian defensive trainer
↓
tactical evaluator
↓
curriculum developer
↓
cognitive-performance innovator.
He repeatedly moved beyond:
What technique should the student perform?
toward:
What information must the student perceive in order to know which technique is appropriate?
That is a deeper instructional question.
His National Tactical Invitational success demonstrated his ability to perform across complex tactical problems.
His work with InSights demonstrated his ability to transfer those skills to others.
His civilian curriculum demonstrated an understanding that special-operations techniques must be adapted rather than copied.
His late work with Dustin Salomon and NURO demonstrated a continuing willingness to update firearms training through developments in cognition, visual processing, and instructional technology.
Within the Extended Primary & Secondary Network, Holschen represents the progression:
technical skill
↓
tactical integration
↓
judgment
↓
perception
↓
cognition
↓
adaptive performance.
That progression captures much of the evolution of serious defensive training over the last three decades.
Early professional firearms instruction understandably concentrated heavily on:
how to operate the gun.
More mature systems increasingly ask:
when, why, and whether the gun should be operated at all.
John Holschen spent much of his career connecting those two questions.
He died unexpectedly in September 2025, leaving behind influence carried by instructors, students, training organizations, and professional peers rather than by a large self-promotional media presence.
That may be the most appropriate description of his professional legacy:
a teacher whose influence became embedded in other teachers.
Concise Professional Description
John Holschen was a retired U.S. Army Special Forces weapons specialist and medic, master combatives and firearms instructor, two-time National Tactical Invitational winner, protective-security practitioner, InSights instructor, and defensive-training innovator whose distinctive contribution was progressively integrating technical shooting, combatives, tactics, judgment, perception, and cognitive processing into a unified model of defensive performance—ultimately helping move firearms instruction beyond predetermined shooting responses toward adaptive decision-making under uncertainty.
