SAS Survival Secrets

I found this vids by chance, there are total 93 vids on SAS Survival Secrets by Bear Grylls. He is the guy behind the Discovery Channel "MAN vs WILD". No doubt it is all about military survival skills but I think it might be helpful to learn something from it. Here is a series of Episode 1/7 part 1/6. Follow this link if you are interested in the whole series.
