Book excerpt: Modern Ninjutsu: A Definitive Guide to the Tactics, Concepts & Spirit of Unconventional Combat Arts is a path guide to realistic training and mind-set development for combat situations wherever they may occur. J. Alaric Justice is a military combat veteran and former anti-terrorist, as well as a former law enforcement defensive tactics instructor and crisis negotiator. Perhaps most important to this work, he has survived many violent street encounters, fights, and attempted crimes in gang-infested areas. Speaking as someone who has been exposed to violence and opponent force in myriad forms, he offers a unique view to practitioners of any system of how to handle crisis situations and maintain realism in their training for generations to come.
