This book explores how Ukraine's traditional Hopak dance conceals centuries of combat knowledge within its movements. Through real accounts from soldiers, civilians, and cultural practitioners, it reveals how these disguised fighting techniques are being revived and adapted for modern warfare and self-defense, showing how cultural traditions can become vital tools for survival when a nation's existence is threatened. The chapters trace Hopak's transformation from folk art to battlefield resource, examining how its kicks, spins, and footwork translate to practical combat skills, how breathing patterns from dance help manage stress under fire, and why this living tradition continues evolving in shelters, military units, and diaspora communities. More than a martial arts study, this work documents how a people's cultural heritage becomes armor when conventional defenses fail, preserving identity while preparing for whatever challenges lie ahead..
