Understanding Functionality Under Weapons-based Violence
FUNCTIONAL UNDER PRESSURE
Understanding Functionality Under Weapons-based Violence
When Violence Erupts, Everything Changes
When violence erupts, plans fall apart, techniques break down, and perfect training quickly collides with imperfect reality. Functional Under Pressure challenges conventional thinking and reveals how truly functional performance is built—not for ideal conditions, but for the chaos, uncertainty, and relentless pressure of real conflict. If you’ve ever wondered why skill doesn’t always survive stress, this book will change the way you think about training forever.
Training is full of certainty. Real violence is not.
For decades, martial artists, military personnel, and law enforcement professionals have searched for better techniques, better drills, and better equipment, believing that success comes from doing more or doing it harder. Yet when the pressure is real, even highly skilled people often discover that what worked perfectly in training suddenly begins to fall apart.
Functional Under Pressure asks a different question. Instead of asking what to do, it asks why performance succeeds—or fails—when time disappears, stress takes over, and the environment refuses to cooperate. Drawing from decades of research, teaching, and experience, Tom Sotis challenges many of the assumptions that have shaped modern training and introduces a practical framework for building skills that survive contact with reality.
This is not another book of techniques. It is a book about functionality—how people perceive, decide, adapt, and perform when everything is on the line. Whether you’re a coach, instructor, competitor, military professional, law enforcement officer, or serious student, Functional Under Pressure will fundamentally change the way you evaluate training, measure progress, and prepare for the unpredictable.
