A friend of mine is a retired seal, hes older now but still an animal, you just talk to this guy and know he was elite, he doesn't brag about it or anything like that but we went hunting and I watched him climb in and out of a tree stand {20ft up} with no ladder, just a short rope he wrapped around the girth of the tree and scooted himself up, he cleared that 20ft faster than I can climb a staircase!!! Also as far as snipers go this guy is the best I have ever seen, on video or in real life, shots that defy logic your brain can comprehend..
He will do something like, one time we were hunting and we came to a muddy hill, I am like "wtf, this is going to suck", and he, with his rifle still infront of him at the ready slides down that hill on his heels with out loosing balance at the bottom, and hardly made a sound doing it, it took me all of 3 minutes to get down and I almost fell 5 times, well he will do something like that and I say "jeezus, you have to be someones here" and he says, "nah' you have to see what the kids are doing now, my day is gone, if we were hard as nailz these new guys are hard as a hammer" .. So I can't imagine how good the new seals are because if he is outdated and I promise you can't think of any one worse to go to war against that this guy, he holds his breath for 4 minutes, he can hide in your bath tub and kill you when you go to get in, lol...
