ZRIntel Insight Magazine
The people behind the perspective.
The ZRIntel Insight Panel is made up of contributing voices whose work reflects different layers of the firearms performance ecosystem. Instruction, equipment, measurement, and operational experience are not separate conversations. They shape the same outcome from different angles.
These are not the only voices on ZRIntel. They represent a working core. New perspectives are always welcome, especially from those operating on the line, at the bench, or inside the system.

Senior instructor at the Federal Law Enforcement Training Center, former senior instructor at SIG Sauer Academy, a retired Green Beret, Kyle is also the author of multiple books on everyday carry and professional firearms training. His work focuses on building sustainable skill through structured progression, bridging the gap between range performance and real-world application.
Drawing on 25 years in federal law enforcement, including roles as a Secret Service Regional Training Program Manager and Academy instructor, Steve examines the gap between what qualification documents and what operational readiness actually requires. His work challenges agencies to move beyond pass/fail records toward evidence of current performance.
A former Delta Force operator, Dale brings direct experience from high-stakes operational environments. His perspective emphasizes mindset, adaptability, and performance beyond static marksmanship.
As both a range executive and instructor, Mike brings direct exposure to large volumes of shooters. His perspective reflects what actually happens during qualifications, including recurring patterns, inconsistencies, and real-world constraints.

Founder and Chief Instructor of Firearms Safety First, LLC, Doc served 17 years as a U.S. Navy Hospital Corpsman, much of it serving alongside Marines. His work centers on judgment-based decision-making, human performance under pressure, and the difference between teaching someone to perform a skill and preparing them to decide when, why, or whether to use it, drawing on his own RIRR (Recognize, Interrupt, Reset, Recover) framework for restoring performance under stress.
