Short Professional Bio
Ken J. Good is a former U.S. Naval Special Warfare operator, longtime military and law-enforcement instructor, low-light tactics pioneer, training-system developer, former Director of the SureFire Institute, co-founder of Strategos International, and founder of Progressive Combat Solutions.
Good served with SEAL Team One after graduating as Honor Graduate of BUD/S Class 105.
His Naval Special Warfare experience encompassed:
- small-unit tactics,
- small arms,
- demolitions,
- communications,
- airborne operations,
- maritime operations,
- intelligence gathering,
- survival,
- and unconventional warfare.
He subsequently spent nearly a decade as Director of Security Forces Training at U.S. Navy Fleet Training Center San Diego, placing him in the important role of translating operational knowledge into repeatable training for other professionals.
Good became especially influential through his work on low-light tactics.
As Director and one of the formative instructors of the SureFire Institute, Good helped develop, test, codify, and teach methods for using handheld and weapon-mounted illumination during armed encounters.
His contribution was larger than developing individual flashlight techniques.
Good approached reduced-light operations as an integrated system involving:
tools + tactics + training + human decision-making.
In his 2001 paper “Let There Be Light: Low-Light Tools, Tactics, and Training,” Good argued that equipment, tactics, and training must be treated as a connected whole.
That systems-oriented approach became an important part of the emerging professional doctrine surrounding tactical illumination.
Good and fellow instructor Dave Maynard are associated with the development and refinement of several influential low-light methods, including the modern Neck Index technique.
Their work helped shift the professional understanding of tactical illumination away from:
flashlight = device used to see in darkness
toward:
illumination = information-management and tactical-control capability.
Good later co-founded Strategos International in 2002, focusing heavily on military and law-enforcement training and reduced-light operations.
He subsequently established Progressive Combat Solutions, where his training continued to integrate:
- firearms,
- tactics,
- decision-making,
- behavioral response,
- human performance,
- and conflict management.
The United States Air Force documented Good training Security Forces personnel in 2014 and described his instruction as combining weapons and tactics with the OODA — Observe, Orient, Decide, Act — decision-making framework.
This reflects the broader evolution of Good’s professional work.
His focus expanded from:
how to use a weapon or flashlight
toward:
how humans perceive information, make decisions, and act during rapidly evolving conflict.
Within the extended Primary & Secondary professional network, Good represents an important earlier generation of professional instructors whose work helped create much of the conceptual foundation later instructors inherited.
His contribution can be summarized as:
operational experience → experimentation → force-on-force testing → doctrine → instructor development → professional adoption.

Long-Form Professional Profile
An Earlier Generation of the Modern Training Community
Ken Good occupies an important position in the development of the modern professional firearms-training community.
Much of what is now considered ordinary tactical-light doctrine was considerably less developed when Good began working on the problem.
Today, professional users routinely discuss:
- handheld versus weapon-mounted illumination,
- searching versus shooting,
- light discipline,
- intermittent illumination,
- identification,
- spill,
- beam characteristics,
- photonic barriers,
- light placement,
- searching techniques,
- and the relationship between illumination and tactics.
Those concepts did not emerge fully formed.
They developed through decades of experimentation by practitioners.
Good was one of the important people involved in that development.
Naval Special Warfare
Good’s professional foundation came through Naval Special Warfare.
He served as an operator with SEAL Team One.
Professional biographies identify him as the Honor Graduate of:
BUD/S Class 105.
His military experience included training and operational preparation involving:
- small arms,
- demolitions,
- small-unit tactics,
- communications,
- long-range patrol,
- airborne operations,
- maritime operations,
- unconventional warfare,
- intelligence gathering,
- and survival.
This provided a broad tactical frame of reference.
Instructor Development
Good subsequently became deeply involved in training.
He served for nearly a decade as:
Director of Security Forces Training
at:
U.S. Navy Fleet Training Center San Diego.
This represents an important transition.
The operational practitioner asks:
Can I perform the task?
The institutional instructor asks:
Can I reliably teach other people to perform the task?
Those are different problems.
From Performance to Curriculum
A good practitioner may perform largely through experience and intuition.
An instructor must identify:
- what matters,
- why it matters,
- how it should be taught,
- what errors are common,
- how performance should be evaluated,
- and how training progresses.
This requires turning:
experience
into
curriculum.
That transition would characterize much of Good’s later career.
The Low-Light Problem
Reduced-light operations create a fundamental information problem.
A firearm may provide the capability to use force.
But before force can be applied appropriately, the user must perceive and understand the environment.
Darkness degrades information.
The professional must answer:
What am I seeing?
Who is that?
What are they holding?
Where are other people?
Where can I move?
What is behind the potential threat?
Illumination therefore becomes part of the decision-making process.
SureFire Institute
Good became one of the central figures in the SureFire Institute, eventually serving as its director.
The institute was an important development because it treated tactical illumination as a subject worthy of dedicated professional study.
The question was no longer simply:
Which flashlight should I buy?
It became:
How should light actually be employed during an armed encounter?
Tools, Tactics and Training
Good articulated his approach particularly clearly in his 2001 article:
“Let There Be Light: Low-Light Tools, Tactics, and Training.”
He argued that:
tools
tactics
and
training
must be considered as an integrated whole.
This is a systems approach.
Equipment Changes Behavior
A tool affects tactics.
Tactics affect training.
Training exposes equipment limitations.
The cycle becomes:
equipment
↓
employment
↓
training
↓
observed problem
↓
equipment or tactical refinement.
Separating those elements can create contradictions.
Flashlight as Information Tool
One of the important conceptual shifts produced by this generation of instructors was understanding that a tactical flashlight is fundamentally an:
information tool.
The purpose is not merely illumination.
The purpose is to obtain enough information to make a better decision.
Detect → Locate → Identify → Decide
The sequence becomes:
detect
↓
locate
↓
identify
↓
evaluate
↓
decide
↓
act.
This directly connects illumination with decision-making.
Light Control
Good became particularly associated with the concept of:
light control.
Light provides information.
But light can also reveal information to an opponent.
The user therefore must consider:
- when to illuminate,
- where to illuminate,
- how long to illuminate,
- when to move,
- and what information the light may provide to another person.
This transforms illumination from a binary concept:
light on / light off
into a tactical problem.
Force-on-Force
Good’s doctrine was heavily informed by simulation and force-on-force training.
This is particularly important.
Many flashlight techniques look effective when demonstrated on an empty range.
The real test is:
What happens when another human is actively trying to defeat you?
Resistance as Quality Control
Force-on-force provides feedback.
Technique
↓
opponent
↓
stress
↓
unexpected response
↓
success / failure
↓
refinement.
This is similar to the methodology underlying other mature performance disciplines.
Tens of Thousands of Simulated Encounters
Good’s later discussions referenced the enormous number of simulated gunfights conducted during the SureFire Institute and Strategos years.
That volume matters because repeated simulation allows instructors to observe patterns.
One incident may be anecdotal.
Thousands of scenarios can reveal recurring tendencies.
Pattern Recognition
The instructor begins asking:
- Which techniques repeatedly succeed?
- Which repeatedly fail?
- What mistakes appear under stress?
- What equipment creates problems?
- What behaviors emerge regardless of what students were told?
This is where simulation becomes a form of professional research.
Neck Index
Good and fellow SureFire Institute instructor Dave Maynard became particularly associated with the refinement of the Neck Index flashlight technique for compact tactical lights.
The technique positions the handheld light near the jaw/neck area.
The larger importance is not the technique itself.
It demonstrates the iterative process through which equipment changes training.
As compact tactical lights became practical, older flashlight methods designed around large police flashlights could be reconsidered.
Technology → Technique
The pathway becomes:
new equipment
↓
new possibilities
↓
experimentation
↓
force-on-force
↓
refined technique.
This is professional adaptation.
Influence on Later Trainers
The persistence of Good’s work is visible in later training culture.
When Thyrm developed its SwitchBack flashlight-retention system, Chris Costa explicitly referenced original flashlight techniques developed by:
Ken Good and Dave Maynard
and explained that the product was intended to remain compatible with those techniques while adding newer capabilities.
That is downstream influence.
Doctrine Becomes Product Requirement
The progression is:
Good / Maynard techniques
↓
professional adoption
↓
later instructor experience
↓
equipment requirement
↓
new product.
A training concept developed years earlier can therefore influence the design criteria of later equipment.
Strategos International
In 2002, Good co-founded Strategos International.
The organization focused on military and law-enforcement training with particular expertise in reduced-light operations.
This extended Good’s influence beyond the SureFire Institute.
Team Tactics
Good’s instruction was not limited to individual flashlight employment.
His courses addressed broader tactical problems including:
- team tactics,
- searching,
- use of cover,
- angles,
- shields,
- firearms,
- and decision-making.
A former NYPD Emergency Service Unit member later described Good’s five-day team-tactics course as having lessons that remained useful throughout his nine years in the tactical unit.
This is a useful measure of instructional durability.
Training That Survives the Class
The real value of instruction is not what appears impressive during the course.
It is:
what the student still uses years later.
That is a much more demanding standard.
Progressive Combat Solutions
Good later founded and developed:
Progressive Combat Solutions.
His work increasingly incorporated decision-making and human behavior alongside technical weapons skills.
This represents a logical evolution.
From Technique to Decision
The early question may be:
How do I use the flashlight?
The deeper question becomes:
When should I use it?
Then:
What information am I trying to obtain?
Then:
How will that information affect my decision?
This moves training progressively upward from mechanics toward cognition.
OODA
Good’s later instruction has made extensive use of the:
OODA Loop
— Observe, Orient, Decide, Act —
originally associated with U.S. Air Force Colonel John Boyd.
The model provides a useful framework for understanding rapidly evolving conflict.
Observe
The person gathers information.
In a low-light environment, illumination directly affects this stage.
Orient
The information is interpreted through:
- experience,
- training,
- expectations,
- context,
- and perception.
Decide
The person selects a course of action.
Act
The decision becomes behavior.
But the environment changes as soon as action occurs.
The loop begins again.
Illumination and OODA
This creates an important connection between Good’s early and later work.
His low-light doctrine concerned:
obtaining and controlling visual information.
His later decision-making work concerned:
processing information into action.
The relationship is therefore:
illumination
↓
observation
↓
orientation
↓
decision
↓
action.
These are not separate subjects.
U.S. Air Force Security Forces
In 2014, the United States Air Force documented Good and Progressive Combat Solutions training more than forty Security Forces personnel drawn from:
- Air Mobility Command,
- Air Combat Command,
- and Air Force Space Command.
The training involved weapons and tactics principles applicable to hostile situations.
Air Force reporting specifically described Good as a:
former U.S. Navy SEAL
and identified the OODA decision-making process as part of the training framework.
This is strong independent evidence of his continued institutional influence decades after his early Naval Special Warfare service.
Institutional Potential
The Air Force reported that the training was being examined with the goal of potentially implementing concepts more broadly within Air Mobility Command.
Again, Good’s work was operating beyond individual commercial students.
The audience included professional organizations considering institutional application.
Active-Shooter Training
Good’s later professional training has also addressed active-shooter response.
This represents another evolution of the same basic problem:
rapidly interpret incomplete information and act under extreme time pressure.
The tactics differ.
The cognitive problem remains similar.
Gladius
Good also became involved in tactical-light product development.
He collaborated with Mike Noell of BlackHawk on the Night-Ops Gladius tactical illumination tool.
Contemporary firearms-industry coverage specifically identified the Gladius as the product of collaboration between Good and Noell.
Practitioner → Product Development
This is another important influence pathway.
Good’s low-light experience created knowledge about what illumination tools needed to accomplish.
That knowledge could then inform equipment development.
The pathway becomes:
operational experience
↓
training
↓
observed equipment limitations
↓
design requirements
↓
product development.
Product and Doctrine
This demonstrates why Good’s tools-tactics-training framework is useful.
Equipment and doctrine evolve together.
A new light creates tactical possibilities.
Training identifies shortcomings.
Those shortcomings inform the next generation of equipment.
Human Performance
Good’s later professional work increasingly focuses on human performance.
This is another logical progression.
The most advanced equipment cannot compensate completely for:
- poor perception,
- bad judgment,
- cognitive overload,
- panic,
- or inadequate training.
The ultimate system is the human being using the equipment.
The Human Is the System
The conceptual hierarchy becomes:
equipment
supports
technique
which supports
tactics
which supports
decision-making
which depends upon
human performance.
Good’s career progressively moved upward through this hierarchy.
Professional Conflict Resolution
His current work through Progressive Combat Solutions increasingly frames the problem as:
professional conflict resolution.
This broadens the focus beyond armed encounters.
The objective becomes understanding how trained professionals manage escalating conflict across a spectrum.
Not every problem requires force.
Not every use of force requires a firearm.
The professional must recognize what problem actually exists.
Primary & Secondary Context
Ken Good belongs in the extended Primary & Secondary network because his work forms part of the professional lineage underlying modern discussions of:
- low-light tactics,
- weapon lights,
- handheld illumination,
- decision-making,
- force-on-force,
- tactical training,
- human performance,
- and professional conflict management.
Many contemporary instructors entered a field in which these concepts were already established.
Good was working on them while the doctrine was still being built.
Institutional Memory
This makes his inclusion especially useful.
Professional communities frequently suffer from:
generational amnesia.
A concept becomes common.
The original reasoning is forgotten.
Later practitioners may assume the technique has always existed.
Documenting people such as Good restores the lineage.
Lineage
The conceptual progression includes:
early tactical illumination
↓
SureFire Institute
↓
Ken Good / Dave Maynard
↓
force-on-force testing
↓
codified low-light doctrine
↓
Strategos
↓
later instructors
↓
modern professional low-light training.
Professional Assessment
Ken Good’s most important contribution is his role in helping transform tactical illumination from an equipment topic into a tactical discipline.
Before mature low-light doctrine, the flashlight could easily be treated as merely an accessory.
Good’s work emphasized that illumination changes:
- perception,
- tactics,
- positioning,
- decision-making,
- and opponent behavior.
Therefore, the flashlight cannot be considered independently from the person using it.
His 2001 tools-tactics-training framework captures this particularly well.
The system is:
tool
↓
technique
↓
tactics
↓
information
↓
decision
↓
action.
Good also recognized the importance of testing ideas through force-on-force.
This provided a mechanism for separating:
techniques that look plausible
from
techniques that survive resistance.
That methodological contribution may be as important as any specific flashlight position associated with his name.
His work also demonstrates substantial downstream influence.
Good and Dave Maynard’s early techniques remained sufficiently influential that decades later modern trainers and equipment designers continued referencing them when developing new tactical-light products.
Good’s later career expanded the same intellectual approach into:
- team tactics,
- OODA-based decision-making,
- active-shooter response,
- weapons handling,
- human performance,
- and professional conflict resolution.
The trajectory is therefore:
Naval Special Warfare operator
↓
military instructor
↓
SureFire Institute
↓
low-light doctrine
↓
force-on-force research
↓
Strategos
↓
product development
↓
Progressive Combat Solutions
↓
decision-making and human performance.
Within the extended P&S network, Good should therefore be understood as an important upstream contributor.
Much of the modern professional firearms community discusses low-light tactics after the discipline matured.
Good helped mature it.
The strongest conceptual description is:
Ken J. Good is a former SEAL Team One operator, military and law-enforcement instructor, former SureFire Institute director and low-light training pioneer whose enduring contribution was helping transform tactical illumination from flashlight technique into an integrated professional discipline connecting equipment, light control, force-on-force testing, tactics, perception and decision-making—and whose later work expanded those principles into team tactics, OODA-based cognition, human performance and professional conflict resolution.
