- Level 11 in the Scientific Fighting Congress (SFC*) Unarmed program (equivalent to 2nd degree black belt)
- Level 11 in SFC Knife
- Level 10 in SFC Pacific Archipelago Combatives (PAC), which includes a lot of Kali and Silat and fighting with two weapons in hand
- 4th degree black belt in tactical ninjutsu (which focuses mainly on taijutsu, Filipino martial arts, Silat, and JKD)
I've also done some training with JKD instructor Tim Tackett, and I draw most of my JKD drills and techniques from his teachings.
* Hock has decided to rename his SFC program to "Force Necessary". This is largely because he is tired of the overuse of the word "combatives" (even though he was the one who drove the word to popularity in the first place). I prefer the SFC name...for the "science". :-)
