Jon “Duffy” Dufresne is a former U.S. Army Ranger, firearms instructor, competitive shooter, tactical educator, consultant, and the founder of Kinetic Consulting. He served with 3rd Battalion, 75th Ranger Regiment, deploying multiple times and developing experience in small-unit tactics, airborne operations, breaching, field medicine, small arms, and related military disciplines. His current work integrates measurable rifle and handgun performance with close-quarters tactics, night vision, low-light operations, law-enforcement firearms-program development, and equipment testing.
After leaving the Army, Dufresne worked in executive protection and law-enforcement consulting before moving more fully into professional firearms instruction. He began teaching professionally around 2015, later taught with Sage Dynamics, and built Kinetic Consulting into a training organization serving responsible private citizens, law-enforcement officers, military personnel, and security professionals.
His work is best understood as an effort to connect measurable shooting performance with tactical application. Technical skill is developed and tested, then placed inside problems involving geometry, movement, communication, low light, uncertainty, and judgment.
Military Experience and Professional Translation
Dufresne’s Ranger Regiment background supplied extensive operational experience, but his later career has focused on translating that experience for different missions and audiences. A technique appropriate for a Ranger assault force may not fit the circumstances, authorities, resources, or responsibilities of a patrol officer, executive-protection professional, or armed citizen.
His post-military work in executive protection and law-enforcement consulting broadened that perspective. Rather than treating military experience as universally transferable doctrine, his instruction emphasizes context: who is acting, what problem must be solved, what support is available, and what consequences follow from the decision.
His time with Sage Dynamics under Aaron Cowan also forms part of his instructional lineage. That experience preceded the development of a distinct Kinetic Consulting curriculum built around mechanics, measurable standards, geometry, night vision, and mission-specific application.
Performance Shooting and Measurable Improvement
Dufresne competes in disciplines including USPSA, 2-Gun, PCSL, PRS, and night-vision matches. He uses competition as a laboratory for technical performance—not as a substitute for tactics. Time, hits, penalties, placement, and comparison expose inefficiencies that subjective impressions can hide.
This produces a practical development cycle: establish current capability, identify a deficiency, practice deliberately, retest, compare performance, and adjust training. The approach asks students to demonstrate improvement rather than merely accumulate repetitions or rely on how a drill felt.
Kinetic Consulting’s handgun and rifle mechanics courses reflect that emphasis. Reliable presentation, recoil management, manipulations, movement, and target transitions provide the foundation. Complexity is added after the shooter can perform and diagnose the underlying mechanics.
CQB and Weaponized Geometry
One of Dufresne’s most distinctive courses is Weaponized Geometry, a single-person building-tactics course centered on using structure and angles to solve dangerous problems. It is not simply a live-fire shooting class or a collection of choreographed room-entry techniques.
The curriculum treats a building as a geometric problem. Angles determine what can be seen, when exposure occurs, how information is gained, and which options remain available. Students learn concepts and techniques, then apply them with non-lethal training ammunition and force-on-force scenarios. The resistance and uncertainty reveal errors that cooperative drills cannot.
This represents a recurring theme in Dufresne’s CQB instruction: geometry before choreography. The goal is not to memorize a universal answer, but to understand visual information, exposure, timing, movement, and risk well enough to make defensible decisions as the problem changes.
Night Vision and Low-Light Operations
Night vision is a major component of Dufresne’s work. His instruction treats it as a complete operating system involving visual limitations, equipment setup, infrared and visible illumination, aiming methods, communications, movement, transitions, and decision-making—not merely wearing goggles while firing a rifle.
Night Vision CQB integrates team movement, structure geometry, deconfliction, low-light transitions, and performance under reduced information. Non-lethal training ammunition allows students to work through demanding problems without turning the course into a sequence of static drills.
Dufresne’s 2024 co-ownership of See the Night extends that involvement into the equipment and education side of the night-vision community. It also reinforces the systems approach found in his teaching: technology creates capability only when selection, setup, maintenance, and practiced skill support the mission.
Law-Enforcement Consulting
Dufresne has consulted with law-enforcement agencies seeking to modernize outdated rifle or firearms programs. That work can include evaluating existing material, supplementing instruction, testing the program against current performance needs, and helping revise curriculum.
The contribution is broader than teaching an individual class. A better institutional program can influence instructors, qualification standards, sustainment training, and generations of officers. His cross-community experience helps him distinguish useful performance principles from practices that do not match an agency’s policy, staffing, equipment, or operating environment.
Equipment Testing and Development
Dufresne also evaluates firearms and related equipment for manufacturers and develops products through Kinetic Consulting. An instructor and active competitor can expose equipment to high round counts, repeated manipulations, varied environmental conditions, and students with different body types and experience levels.
That perspective makes equipment evaluation an extension of instruction. A product should solve a real problem, integrate with the rest of the user’s system, and remain reliable under sustained use. Dufresne has emphasized candid feedback when equipment does not perform as intended, helping connect field experience with practical product refinement.
Teaching Philosophy
Dufresne’s teaching style combines direct standards with an approachable delivery. Humor can reduce unnecessary tension, but it does not replace accountability. Students are expected to perform safely, evaluate results honestly, and understand why a technique works rather than copy an instructor’s movement without context.
He also emphasizes learning how to learn. Effective students arrive prepared, ask useful questions, record meaningful observations, diagnose problems, and leave with a plan for continued practice. That focus increases the value of a class because development continues after the formal course ends.
Across firearms mechanics, CQB, force-on-force, and night vision, the consistent progression is mechanics → measurable performance → contextual application → tactical problem solving.

Professional Assessment
Jon Dufresne is an influential contemporary firearms and tactical instructor whose strongest contribution is the integration of measurable shooting skill with mission-specific application. His Ranger Regiment service provides operational depth, while his later work in protection, law-enforcement consulting, competition, instruction, and equipment development gives him a wider frame for deciding what transfers—and what does not.
Kinetic Consulting’s curriculum reflects that synthesis. Mechanics must be reliable. Performance must be observable. Equipment must support the task. Tactics must account for geometry and incomplete information. Night-vision technology must be integrated into a practiced system. Above all, the method must fit the mission and the student.
Current Work
Dufresne continues to own and lead Kinetic Consulting, teaching civilian, law-enforcement, military, and security-industry students. Current Kinetic offerings span shooting mechanics, law-enforcement training, Weaponized Geometry, night-vision instruction, equipment rentals, and related products. He also remains a co-owner of See the Night, a role he assumed in 2024.
