Professional Biography

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 background encompassed small-unit tactics, small arms, demolitions, communications, airborne and maritime operations, intelligence gathering, survival, and unconventional warfare.

He later spent nearly a decade as Director of Security Forces Training at U.S. Navy Fleet Training Center San Diego. That position required translating operational knowledge into structured curriculum that other professionals could understand, practice, evaluate, and apply.

SureFire Institute and Low-Light Doctrine

Good became especially influential through his work on reduced-light operations. As Director and one of the formative instructors of the SureFire Institute, he helped develop, test, codify, and teach methods for employing handheld and weapon-mounted illumination during armed encounters.

His contribution extended beyond individual flashlight positions. Good treated reduced-light work as an integrated system connecting tools, tactics, training, perception, movement, information control, and human decision-making.

His 2001 paper, “Let There Be Light: Low-Light Tools, Tactics, and Training,” clearly presented that systems approach. Equipment affects tactics; tactics determine training requirements; training exposes equipment and procedural limitations; and those observations drive further refinement.

Illumination as Information Management

Good helped advance the professional understanding of a tactical light as an information tool rather than merely a device used to see in darkness. Illumination supports detection, location, identification, evaluation, decision-making, and action.

Light also creates risk because it can reveal information to another person. The user must consider when and where to illuminate, how long the light should remain active, when movement is appropriate, what the beam reveals, and what information the light may provide to an opponent.

This emphasis on light control helped move tactical illumination from an equipment topic into a professional discipline involving positioning, perception, identification, opponent behavior, and judgment.

Force-on-Force Testing

Good’s low-light doctrine was heavily informed by simulation and force-on-force training. Techniques that appear convincing on an empty range may fail when another person actively resists, moves unpredictably, exploits light, or creates stress and uncertainty.

Repeated scenarios provided a means of quality control. Instructors could observe which techniques survived resistance, which errors repeatedly appeared under stress, how equipment affected behavior, and where training needed revision. Good’s later discussions referenced tens of thousands of simulated encounters conducted during the SureFire Institute and Strategos years.

This methodology may be as important as any individual flashlight technique associated with his name. It established a process of experimentation, resistance, observation, and refinement rather than relying solely on plausibility or authority.

Neck Index and Tactical-Light Technique

Good and fellow SureFire Institute instructor Dave Maynard became associated with the development and refinement of the modern Neck Index technique for compact handheld lights. The method positions the light near the jaw and neck while allowing the user to direct illumination with head and upper-body movement.

Its broader significance is the adaptive process behind it. Compact tactical lights created possibilities that differed from methods developed around large police flashlights. New equipment was evaluated through experimentation and force-on-force work, producing revised technique.

The durability of this influence is visible in later equipment development. When Thyrm developed the SwitchBack flashlight-retention system, Chris Costa publicly referenced original techniques developed by Good and Maynard as part of the professional lineage informing the product.

Strategos International

Good co-founded Strategos International in 2002. The organization extended his work in military and law-enforcement training, reduced-light operations, team tactics, searching, use of cover, angles, ballistic shields, firearms, and decision-making.

This expanded the low-light problem from individual flashlight employment into coordinated tactics. The standard for useful instruction became what trained professionals could still apply under pressure and years after the course, rather than what appeared impressive during a demonstration.

Progressive Combat Solutions

Good later established Progressive Combat Solutions. His training increasingly integrated firearms and tactics with perception, orientation, behavioral response, human performance, and professional conflict management.

This represents a logical progression in his career. The initial mechanical question—how to use a weapon or flashlight—leads to higher-order questions: When should it be used? What information is needed? How will that information be interpreted? What response fits the problem actually present?

OODA and Decision-Making

Good’s later instruction has made extensive use of the OODA framework—Observe, Orient, Decide, Act—associated with U.S. Air Force Colonel John Boyd. The model provides a useful way to understand rapidly changing conflict.

Good’s earlier and later work connect directly. Tactical illumination helps obtain and control visual information during observation. Training and experience shape orientation. The resulting interpretation supports a decision, which becomes action and changes the environment.

In 2014, the U.S. Air Force documented Good and Progressive Combat Solutions training Security Forces personnel from multiple major commands. Air Force reporting identified his Naval Special Warfare background and described the OODA decision-making process as part of the weapons-and-tactics instruction.

Product Development

Good also contributed to tactical-light product development. He collaborated with Mike Noell of BlackHawk on the Night-Ops Gladius tactical illumination tool. Contemporary industry reporting identified the product as a joint development informed by Good’s low-light background.

This work reflects the tools-tactics-training relationship central to his doctrine. Operational and instructional experience identifies equipment limitations; those limitations become design requirements; new equipment creates additional tactical possibilities; and training tests the resulting product.

Primary & Secondary Connection

Good is included 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, force-on-force training, team tactics, decision-making, and human performance.

Many contemporary practitioners entered a field in which these concepts were already established. Good was working on them while the discipline was still being developed, tested, and codified. Documenting that lineage helps preserve the reasoning behind techniques that later generations may otherwise treat as having always existed.

Professional Significance

Ken Good’s most important contribution is helping transform tactical illumination from a collection of flashlight techniques into an integrated professional discipline connecting equipment, light control, force-on-force testing, tactics, perception, and decision-making.

His career progressed from Naval Special Warfare operator to institutional instructor, SureFire Institute director, low-light doctrine developer, Strategos co-founder, product-development collaborator, and founder of Progressive Combat Solutions. His later work expanded the same systems-oriented approach into team tactics, OODA-based cognition, human performance, and professional conflict resolution.
