Was watching a programme on TV last night here in the UK which shows the SAS in training (with there faces blurred of course), how they deal with different scenarious etc.
It was interesting to see that when they did empty hand to hand and empty hand against a knife attack the techniques were nearly identical to that of mantis techniques that I have come across in my training so far, you could even spot the horse stance there used for take-downs :-)
Just thought it might be of interest to you all.
