A Defense Manual of Commando Ju Jitsu originally published in 1943 was designed to teach Ju Jitsu techniques for self-defense that can be applied under any circumstance.

This unique manual born out of wartime is structured to easily convey multiple techniques (Locks, Breaks, Throws, Chokes, etc.) in a simple and effective manner. Accompanied with multiple photographs and sketches, this manual is an invaluable addition to any beginner or experienced martial artist.
