I've had several friends over the years who were Special Forces, SEALs, or Marine Recon. (In fact, my friend Phil -- Marine Recon -- has a cameo in the movie "Heartbreak Ridge"; he's the Marine coming out of the shower as Mario Van Peebles starts playing "Bionic Marine".)
Anyway, they unanimously agreed that their Special Operations training was the hardest thing that they have ever done -- and that the first ones to wash out of the training were almost the always the ones who had come swaggering in with the "I wanna be a Green Beret/SEAL/Recon Marine because I'm a real bad
."
I've never been dumb enough to want to go Special Operations.
There's always been other stuff to do.
