Law enforcement trainer John Chappy Chapman published a guest post on November 9, 2026, describing lessons from training several thousand students nationwide. He estimated that roughly one fifth of students who already shoot well lose either gun handling or, more often, decision making when asked to issue commands or move to a better position while holding a subject at gunpoint.

Chapman now designs courses from the mission backward so that marksmanship, verbal commands, movement, and subject control are trained as layered skills that remain available when attention must go to whether force is appropriate. He applied the same standard to equipment, arguing that gear such as Blue Force Gear pouches and the MARCO marking light dispenser should work without pulling focus from communication, movement, or changing conditions. Chapman, who has more than 34 years in operational and training roles and directs the Task Force 70 Foundation, said instructors, students, and companies must test assumptions under realistic conditions.
