Combatives martial arts styles

[Icelander]

In my current modern world campaign, military hardware and martial arts are one of the mainstays. This renders it somewhat impractical for me to switch over to 4e for that campaign, as the books High Tech and Martial Arts for 4e have not yet been published, while the previous edition had quite functional and enjoyable rules for guns and unarmed fighting.

As a consequence, I find myself still using the 3e Martial Art styles regularly during play. The addition of manoeuvres and secondary skills add verisimilitude and combine to make PCs specialising in the various styles distinct from each other. However, while the 3e Martial Art book covers a large variety of styles, it is all but impossible to shoehorn every form of martial art into a single sourcebook.

I know that people here overwhelmingly use 4e rules, but I suspect that there are many who still remember the rules of the previous edition and anyone who bets against GURPS players being intimately familiar with real world phenomena as it relates to gaming is looking to lose money. Therefore, I ask you, my fellow Internet geeks, if anyone has ideas on how best to represent the following styles using 3e Martial Arts rules:

Anti Terror Kampf

Brazilian Jiu-Jitsu

Combat SAMBO

Krav Maga

MCMAP

S.C.A.R.S.

Systema

I am aware that many of them could be represented by the Military Hand-to-Hand style, with perhaps a little Fairbairn system thrown in, but I am looking for a little more detail than that. 4e suggestions are welcome as well, since converting should be a breeze and I will probably do it as soon as 4e Martial Arts comes out anyway.
