Combatives martial arts styles

[Lord Carnifex]

Luther's version of Old-Style Brazilian Juijutsu ought to work well... perhaps a more modern grappling/groundfighting style incorporating Juijutsu elements might look like:

Combative Juijutsu
Primary skills: Wrestling
Secondary skills: Judo, Brawling
Maneuvers: Arm lock, Choke Hold, Ground Fighting (Wrestling), Ground Fighting (Brawling), Head Lock, Leg Grapple.

[note:] I make wrestling the primary skill here, because the style emphasises going to the ground with your opponent (which I see as GURPS Wrestling skill) rather than throwing your opponent to the ground while you remain upright (which I see as being more the province of GURPS Judo Skill).

It's not a stand alone art... you'd probably want to train it in conjunction with Muay Thai, Kali (GURPS 3e Escrima), or Jun Fan (GURPS 3e Jeet Kune Do) or some form of upright military hand-to-hand.

The thing to remember is that while Gracie Juijutsu is a very effective, very efficient style for groundfighting, it does not particularily emphasise upright fighting or speedy resoultion. A juijutsu fighter will usually be looking to take an opponent to the ground and force him to submit through manuvering and endurance. In a modern battlefield or street-fighting situation, there's often not much opportunity for one-on-one fighting, and going to the ground is not always a good idea.
