Primary & Secondary — Chad Halvorson:
https://primaryandsecondary.com/author/chad-halvorson-us/
Short Professional Bio
Chad Halvorson is a veteran law-enforcement officer, firearms instructor, active-shooter instructor, former tactical-team member, academy adjunct instructor, published firearms-training writer, and Primary & Secondary contributor whose professional work has emphasized patrol-level capability, practical firearms training, active-threat response, interdisciplinary emergency response, and continuing professional education.
According to his Primary & Secondary professional biography, Halvorson was sworn in as a police officer in 1994.
His law-enforcement experience has included work as a:
- patrol officer,
- deputy sheriff,
- tactical-team member,
- arson investigator,
- narcotics investigator,
- firearms instructor,
- active-shooter instructor,
- Tactical Response instructor,
- and adjunct instructor at regional law-enforcement academies.
Halvorson’s tactical-team experience included serving for several years as a point man on the entry element of a Special Operations tactical team, with less-lethal responsibilities as a secondary assignment.
His instructional experience has included:
- law-enforcement firearms,
- patrol-carbine deployment,
- active-shooter response,
- tactical-team tactics,
- use-of-force judgment,
- scenario-based training,
- concealed-weapons instruction for citizens,
- and academy-level Tactical Response training for patrol officers.
A particularly important part of Halvorson’s professional work involved helping area law-enforcement agencies integrate active-shooter response with Fire and EMS personnel.
That work reflects an important evolution in active-threat response.
The problem is not solved merely when police confront the threat.
The larger public-safety objective is:
stop the threat
↓
reach the injured
↓
begin treatment
↓
move casualties
↓
coordinate continuing response.
This requires police, fire, and emergency medical personnel to understand one another’s capabilities, limitations, terminology, and operating requirements.
Halvorson’s experience therefore sits at an important intersection:
patrol
tactics
firearms
active-threat response
emergency medicine integration
instruction.
He has also maintained a strong emphasis on continuing professional development outside institutional minimums.
His four-part Primary & Secondary account of Sentinel Concepts Practical Urban Carbine illustrates this particularly well.
Rather than treating an after-action review as a simple course recommendation, Halvorson documented:
- instructional methodology,
- equipment,
- shooting problems,
- optics,
- positional shooting,
- low-light work,
- student learning,
- note taking,
- performance standards,
- and lessons that could be carried into future practice.
His writing repeatedly emphasizes that training should produce:
learning
rather than merely:
round count.
That distinction is central to his professional contribution.
Halvorson’s work represents the experienced patrol officer who continues deliberately expanding his frame of reference and then transfers useful lessons to:
- other officers,
- instructors,
- students,
- agencies,
- and the broader professional community.

Long-Form Professional Profile
Patrol as the Foundation
Chad Halvorson’s professional identity begins with patrol.
Primary & Secondary’s biography describes him as a:
“patrol officer at heart.”
That description is significant.
Patrol is where many separate law-enforcement disciplines converge.
The patrol officer may be required to transition rapidly between:
- routine public interaction,
- investigation,
- crisis intervention,
- emergency driving,
- medical response,
- arrest,
- firearms,
- tactics,
- and use-of-force decision-making.
The officer cannot specialize in only one of these areas.
The Generalist Problem
Specialized units can concentrate on narrow missions.
Patrol cannot.
The patrol officer must maintain:
broad competence across many disciplines.
That makes patrol one of the most demanding environments for practical training design.
Training must account for the reality that officers have:
- finite time,
- finite ammunition,
- finite agency resources,
- competing training requirements,
- and widely varying levels of experience.
The important question therefore becomes:
What skills provide the greatest practical return?
That question appears repeatedly in Halvorson’s professional development and writing.
Rural Law Enforcement
Halvorson’s career included many years working in rural environments as both a deputy sheriff and police officer.
Rural law enforcement creates its own operational requirements.
Resources may be:
- farther away,
- fewer in number,
- slower to arrive,
- or unavailable altogether.
This can increase the importance of individual officer capability.
Self-Sufficiency
The rural officer may need greater ability to:
recognize
↓
decide
↓
act
↓
stabilize
before specialized resources arrive.
That reality reinforces the value of broad professional competence.
Tactical-Team Experience
Halvorson also spent several years assigned to a Special Operations tactical team.
His P&S biography identifies him specifically as a point man on the entry team, with less-lethal responsibilities as an additional assignment.
That experience provided exposure to a more specialized tactical environment.
But its greatest value for the broader professional community may be what could subsequently be transferred back to patrol.
Tactical Knowledge to Patrol
Specialized tactical units can develop:
- movement,
- communication,
- weapon handling,
- problem-solving,
- and team-coordination skills
at a level patrol officers may have fewer opportunities to practice.
However, tactical-team methods cannot simply be copied wholesale into patrol.
The mission is different.
Translation
The important process is:
specialized experience
↓
identify transferable principles
↓
adapt to patrol resources
↓
teach patrol officers.
This is more useful than attempting to turn every patrol officer into a tactical-team operator.
Investigation
Halvorson’s assignments also included:
- arson investigation,
- and narcotics investigation.
These assignments add another dimension to his professional frame of reference.
Investigation requires a different cognitive mode than immediate tactical response.
The investigator must:
- collect information,
- evaluate competing explanations,
- recognize inconsistencies,
- document evidence,
- and avoid premature conclusions.
This reinforces a broader professional theme:
observe before assuming.
Instructor Development
Halvorson became a certified law-enforcement instructor in his state.
His certifications included:
- firearms instruction,
- active-shooter instruction,
- and Tactical Response.
He also worked as an adjunct instructor at regional law-enforcement academies.
This represents an important transition:
practitioner
↓
instructor.
The two roles are related but not identical.
Knowing vs Teaching
Being capable of performing a task does not automatically mean someone can teach it.
Instruction requires the ability to:
- explain,
- demonstrate,
- diagnose,
- correct,
- structure practice,
- evaluate performance,
- and communicate why the skill matters.
The instructor therefore needs another layer of professional development.
Patrol-Carbine Deployment
Halvorson’s instructional work included patrol-carbine deployment.
The term “deployment” is important.
Teaching someone to shoot a carbine is only one component.
Operational deployment also involves questions such as:
- when the rifle should be accessed,
- how it is carried,
- how it interfaces with other equipment,
- how officers move with it,
- how it is used around other personnel,
- and how its capabilities affect tactical decisions.
The weapon exists inside an operational system.
Firearms Training as Problem Solving
Halvorson’s four-part Primary & Secondary series covering Sentinel Concepts Practical Urban Carbine provides especially useful insight into his training philosophy.
One of his strongest observations was that the course was not simply:
a shooting class.
It was a:
problem-solving class.
That distinction is fundamental.
Shooting vs Solving
A shooting exercise asks:
Can you perform this shooting task?
A tactical problem asks:
Can you recognize what the problem requires and select an appropriate solution?
The second demands more than mechanical skill.
It requires:
- observation,
- judgment,
- adaptation,
- and decision-making.
Round Count Is Not Learning
Halvorson’s AAR specifically addressed students who were concerned about the relatively slow pace and limited ammunition expenditure.
His conclusion was essentially that:
round count does not equal training value.
He reported firing fewer than three magazines during one training day while still finding the instruction highly productive.
This illustrates an important training principle.
Activity ≠ Learning
A student can fire:
500 rounds
and learn relatively little.
Another student can fire:
60 rounds
while receiving:
- observation,
- correction,
- explanation,
- dry practice,
- measurement,
- and reflection
and make substantial improvement.
Therefore:
activity
should not be confused with
learning.
Performance-Based Training
Halvorson noted that range time was based on performance rather than predetermined ammunition expenditure.
This changes the objective.
Instead of:
complete X number of repetitions
the objective becomes:
demonstrate the required result.
That creates accountability.
Dry Practice
He also emphasized that some skills were initially practiced dry.
This reinforces another useful principle:
ammunition is not required for every useful repetition.
Dry work can isolate:
- movement,
- position,
- manipulation,
- visual processing,
- and technique
without recoil or ammunition expenditure.
Observation as Training
Halvorson’s writing also demonstrates that he did not regard waiting for another shooter as wasted time.
He used the opportunity to:
watch other students.
This is an important adult-learning concept.
Every student creates another example.
The observer can see:
- different body types,
- different equipment,
- different mistakes,
- different corrections,
- and different solutions.
One Student’s Correction Teaches Everyone
The process becomes:
student performs
↓
instructor diagnoses
↓
instructor corrects
↓
entire class observes
↓
everyone gains another reference point.
This makes observation part of training.
Note Taking
One of Halvorson’s strongest recommendations was extremely simple:
take notes.
He specifically expressed surprise that relatively few students were doing so.
This reflects a larger issue in professional education.
Memory Is Imperfect
Training environments generate enormous amounts of information.
Without documentation:
instruction
↓
short-term memory
↓
new information
↓
interference
↓
forgotten detail.
A notebook creates external memory.
Notes Extend Training
The process becomes:
class
↓
notes
↓
review
↓
practice
↓
retention.
This extends the value of the course long after the student leaves.
After-Action Reviews as Knowledge Transfer
Halvorson’s P&S Practical Urban Carbine series was intentionally detailed.
He explained that his AARs were less focused on traditional military problems-and-corrections formatting and more focused on:
lessons learned.
His goal was to give readers enough information that they could also extract useful lessons from his experience.
That makes the AAR a form of:
knowledge transfer.
Student → Writer → Reader
The pathway becomes:
instructor
↓
Halvorson as student
↓
experience
↓
written analysis
↓
P&S reader
↓
future training decision or practice.
One seat in a class can therefore influence far more than one student.
Steve Fisher / Sentinel Concepts
Halvorson’s four-part series documents training with Steve Fisher and Sentinel Concepts.
His assessment emphasized Fisher’s practical and evidence-oriented instructional approach.
Halvorson specifically valued instruction supported by:
- experience,
- research,
- validation,
- and practical application.
This is an important epistemic standard.
Why?
The mature student should ask:
Why is this being taught?
The instructor should have a better answer than:
because I said so.
Useful instruction should connect technique with:
reason.
Multiple Solutions
Halvorson also praised an instructional approach that presented multiple ways of solving problems rather than insisting on a single universal method.
That is especially important in tactical instruction.
People differ.
Problems differ.
Equipment differs.
Contexts differ.
Principle Over Dogma
The mature approach becomes:
understand the principle
↓
understand available methods
↓
select the method appropriate to the situation.
This is superior to technique worship.
Pat Rogers and EAG Tactical
Halvorson’s professional training also intersected the Pat Rogers / EAG Tactical lineage.
His S.W.A.T. Magazine article on the EAG Tactical Shoot House/Combat Lifesaver Course documented training combining tactical problem-solving with lifesaving medical capability.
This combination is particularly relevant to his later active-threat work.
Winning the Fight Is Not the End
An active violent event does not end simply because the threat stops.
People may still be:
- bleeding,
- trapped,
- disoriented,
- or dying.
Therefore:
tactical success
must transition into
medical response.
Tactical Medicine
Halvorson’s exposure to integrated tactical and lifesaving training reinforced a broader professional requirement:
people who go in harm’s way may need to keep someone alive afterward.
That principle increasingly influenced modern law-enforcement training.
Active-Shooter Instruction
Halvorson became certified as an active-shooter instructor and taught active-shooter response and tactics.
This is particularly important in the context of patrol.
Modern active-shooter doctrine increasingly recognizes that patrol officers may need to act before specialized teams arrive.
Time Matters
In an ongoing active-threat event:
delay
can have direct consequences.
Therefore the patrol officer needs sufficient:
- firearms competence,
- tactical understanding,
- decision-making ability,
- communication,
- and confidence
to respond with available resources.
Police + Fire + EMS
Halvorson’s work helping law-enforcement agencies integrate active-shooter response with Fire and EMS is one of the most significant aspects of his professional biography.
Historically, these disciplines sometimes trained separately.
But a mass-casualty attack creates one shared problem.
Different Missions, Shared Objective
Police focus on:
threat control.
Fire/EMS focus on:
casualty treatment and evacuation.
The objectives must eventually converge.
Integrated Response
The operational sequence becomes:
threat
↓
law-enforcement intervention
↓
risk reduction
↓
medical access
↓
treatment
↓
evacuation.
If the disciplines do not understand one another, unnecessary delay can occur.
Interoperability
This makes integrated training a form of:
interoperability.
Interoperability is not merely compatible radios.
It means different organizations can work effectively toward a shared objective.
Common Mental Model
Effective joint response requires a shared mental model.
Participants need to understand:
- terminology,
- priorities,
- movement,
- acceptable risk,
- communication,
- and expected actions.
Training builds that shared model before the emergency occurs.
Scenario-Based Training
Halvorson’s instructional experience also included:
use-of-force judgment and scenarios.
This represents another important progression beyond marksmanship.
Can Shoot vs Should Shoot
Traditional firearms training often measures:
Can the officer hit the target?
Scenario training introduces another question:
Should the officer shoot at all?
That is fundamentally different.
Decision Training
The officer must:
observe
↓
interpret
↓
decide
↓
act
↓
reassess.
This better reflects real-world use-of-force problems.
Primary & Secondary Contributor
Halvorson’s four P&S articles make him a direct contributor to the site’s early professional knowledge base.
The P&S author archive continues to identify him as the author of four articles.
All four form a detailed examination of the Sentinel Concepts Practical Urban Carbine course.
The series is valuable because it documents more than equipment or drills.
It documents:
how a professional student learns.
Learning How to Learn
That may be the most interesting aspect of Halvorson’s writing.
He pays attention not only to:
what Steve Fisher taught
but also:
how the course was structured
and
why the learning occurred.
That includes:
- pace,
- observation,
- dry practice,
- notes,
- feedback,
- repetition,
- performance standards,
- and discussion.
This is instructor-level analysis.
Professional Assessment
Chad Halvorson’s contribution to the Extended Primary & Secondary Network is best understood through the concept of the:
professional patrol generalist who deliberately develops specialist knowledge and returns it to the generalist environment.
His career begins with patrol.
From there it expands through:
patrol
↓
tactical-team experience
↓
investigations
↓
firearms instruction
↓
active-shooter instruction
↓
academy instruction
↓
outside professional training
↓
Fire/EMS integration
↓
written knowledge transfer.
This creates a particularly useful type of professional.
Halvorson is not defined by one narrow specialty.
Instead, his value comes from connecting specialties back to the patrol mission.
Tactical-team knowledge becomes relevant to patrol response.
Firearms knowledge becomes relevant to patrol-carbine deployment.
Medical knowledge becomes relevant to active-threat response.
Scenario training connects shooting ability with judgment.
Outside training challenges institutional assumptions.
Detailed after-action reviews distribute lessons beyond the original classroom.
His writing also demonstrates a mature distinction between:
training activity
and
learning.
More rounds do not automatically create more skill.
Faster pacing does not automatically create better instruction.
Watching another student can be productive.
Dry practice can be productive.
Taking notes can be productive.
Reflection can be productive.
The relevant question is:
Did learning occur?
That perspective is especially valuable for law-enforcement agencies, where training resources are always limited.
Halvorson’s active-threat integration work adds another important dimension.
A modern critical incident does not respect organizational boundaries.
Police, fire, and EMS must eventually solve the same problem together.
His work helping those disciplines integrate active-shooter response reflects an understanding that capability exists not only at the individual level but also at the:
system level.
The resulting professional model is:
individual competence
↓
team competence
↓
interagency coordination
↓
community capability.
Within Primary & Secondary, Halvorson’s contribution also illustrates how a professional network multiplies training.
One officer attends a course.
He documents it carefully.
Thousands of readers can examine his observations.
Other instructors compare those lessons with their own experience.
Useful ideas continue moving.
That is:
training
↓
reflection
↓
documentation
↓
distribution
↓
professional discussion
↓
institutional knowledge.
The strongest concise description is:
Chad Halvorson is a veteran law-enforcement officer, firearms and active-shooter instructor, former tactical-team member, academy adjunct instructor and Primary & Secondary contributor whose distinctive professional contribution lies in connecting practical patrol experience with specialized tactical training, scenario-based decision-making, active-threat response, Fire/EMS interoperability and deliberate knowledge transfer—emphasizing that meaningful training should develop problem-solving capability rather than simply generate activity or round count.
