|American Combat Judo was
named by Bernard Cosneck originally for the Coast Guard during WWII and
was specifically designed as a self-defense/offensive method for
military personnel. Focusing on rapid disposal of attackers,
Combat Judo, unlike Law Enforcement techniques, does not attempt to
control the attacker. The Israeli Defense Forces' Krav Maga
system, which breaks down combat material to pragmatic actions, is
probably closest to Combat Judo.
Combat Judo revives the more dangerous Jujitsu techniques that formed the basis for sport Judo. It seeks to quickly defeat the opponent, allowing the option to finish with more drastic techniques, enabling the defender to focus on the next attacker. Unlike sport Judo, no rules apply.
Cosneck, Fairbairn, and Applegate were the first Westerners to define the military aspect of Kano’s original Judo system (which borrowed heavily from Jujitsu) and use Combat Judo. Several Allied Forces used the term, but Cosneck was one of the first to define it in his 1944 book, "Combat Judo." Ernie Cates, a 1950s Combat Judo instructor and Marine Judo champion, used a similar format, calling it "Judo with an attitude.”
Combat Judo survives in a number of styles that incorporate Judo’s original Atemi Waza with the more lethal aspects of Jujitsu. Instructors in Krav Maga and Fort Bragg’s Delta Force have refined and specialize in the "Kill or Be Killed” aspects of Combat Judo. Sadly, Special Forces Rangers now focus on Gracie Jujitsu, ending up grappling with single opponents while “number two” kicks in their skull.
British Officer Fairbairn also taught a form of Combat Jujitsu that he’d learned in China and which was similar to older Jujitsu styles from Kano’s Judo in which Atmei Waza was prominent, to the OSS. He described this in his 1942 book, "Get Tough."
Some Jujitsu instructors emphasize wrist manipulations, actions which provide examples of Jujitsu's principles in body mechanics but have little pragmatic use in fast moving, reactive combat. Essentially they are a training tool for understanding basics, hence more suited as control holds for law enforcement personnel. Throws such Kubi Nage (Goshi Guruma), O Soto Gari, Harai Goshi, and Seoi Nage are useful in Combat Judo, but only when coupled with finishing techniques.
Combat Judo minimizes time required to learn more complicated contest Judo techniques such as Uchi Mata or Tai Otoshi, which offer opponents opportunity to hang on and drag one to the ground. For example, contest-practical Maki Komi gets attacker and defender to the ground without disabling the attacker.
Most Kansetsu and Osaekomi Waza are impractical in Combat Judo
because they rely on control and submission rather than disposal of an
opponent. In hand-to-hand combat, “number two” is always close
by to kick you in the head! Learning to escape from ground holds
is critical, since many fights end up there if you do not dispose of
your opponent quickly (the real objective of Combat Judo) while
Combat Judo has improved since WWII, with styles such as Krav Maga
far more pragmatic than what was taught in the old days. Krav Maga
has undergone many changes since its development. Krav Maga’s
philosophy basically is to eliminate the superfluous and use the
simplest effective techniques for combat conditions, much like Combat
Different styles, such as Spetsnaz doing Sambo or Israeli Defense Forces doing Krav Maga, can be just as effective as one's own Combat Judo style. Martial artists should have sufficient humility to accept that other styles and techniques actually may be more effective than their own.
"The Complete Kano Jiu-Jitsu," 1935 edition, shows basics
that we use today. Books and videos however are no substitute for
being on the mat with a knowledgeable instructor.
Mastery of a few techniques is better than familiarization with many.
A throw such as Kubi Nage is most effective to break through a boxer's
aggression, allowing for powerful elbow strikes after the opponent has
panicked and hugged and pulled you to the ground.
