Very hard to find Target Focus Training (TFT) sourcebook by Chris Ranck Buhr and Tim Larkin—a practical self-defense manual focused on injury mechanics, anatomical targets, and simple high-leverage movements for real-world personal protection. Clear, direct instruction emphasizes natural body movement, situational awareness, and drilling key strikes without complex choreography. Useful for martial arts students, security professionals, and anyone building a home study library in combatives and personal safety. Great companion to TFT video courses.
