I had never heard of this before.
I've done it for two years a while ago, it's quite interesting. Obviously, not all self-defense techniques learned there involve kicking your opponent in the groin, but as I said, it's certainly not above doing that.
It's meant for the streets, after all, not for the ring.
You learn to defend against all kinds of situations, including strangulation, knife or gun attacks, and good old-fashioned fisticuffs, of course. Note that it's a purely defensive martial art, so you don't learn how to do any of that yourself, just how to get out of it in one piece if there's no other way. Sometimes you just practice behavior in potential conflict situations that may not even require you to get physical. We even did a seminar one weekend that involved simulated kidnappings and hostage situations.
One technique I have learned there, which was also taught to me when I did some police training a few years ago, was to use open palm strikes instead of fist punches when you need to defend yourself. The idea is to reduce the likelihood of drawing blood from your opponent, which may be a safety issue, especially if you're fighting some junkie at the train station or something. It seems counter-intuitive, though, not sure if I would ever use that in such a situation - but let's hope it won't ever be necessary either way.
But yes, it was quite fun, and it does enable you to carry yourself more confidently. It's not like I'm all that concerned about my physical safety in that peaceful little town of mine, but you never know - especially because it may sometimes be necessary to step up on someone else's behalf too.
