Defendo vs. Defendo vs. Defendo
Just noticed there are three separate martial arts called Defendo developed by completely different people.
There's Defendo created by William E. Fairbairn and Eric Anthony Sykes. It's actual name is Defendu but many (most?) of its practitioners call it Defendo. It's a close quarter combatives system taught to soldiers during World War II that emphasized lethal force. From what I read, it's got the most confirmed casualties of any close quarter system -- probably just because World War II had a lot of casualties in the first place.
Then there's Defendo created by Bill Underwood. This system came from an earlier system called Combato. Likewise, this was taught during World War II -- but to law enforcement instead and emphasized compliance instead of lethal force. Apparently, this was the first actual system called Defendo since Fairbairn really called his system Defendu.
Finally, there's Defendo created by W.H. Wolfe. This one is actually Modern Defendo and is slightly based on Defendu, but is really quite different.
Defendo (a.k.a., Defendu) was created by a Brit. Defendo (a.k.a., Combato) was created by another Brit who emigrated to Canada. Defendo (a.k.a., Modern Defendo) was created by a Canadian.
So, does anyone here practice Defendo? If so, what are your feelings about the other forms of Defendo?
