I always wondered how they made Matt Damon seem like such a badass, I met him for a while when I was bouncing at sundance a couple years ago. He's roughly the size of my ten year old. He's tiny.
He bumped me and I turned around and looked at him (without realizing who he was) and he just said : "you scare me" and started backing up.
I wish I would have lectured him on concealed carry and civilian handgun owners since he's an anti but then some stupid chicks started going all crazy and I had to protect him from the wild 13 year olds, most of which were bigger than he was.
The special forces guys I've met were very quiet, very subtle. Only a couple will tell you stories, one of them just retired from the special forces management at bragg. My favorite story was when he almost shot down an A10 with a telephone pole during training exercises and when he bet some grenadian army guys they couldn't hit a satelite dish from a long distance with a grenade launcher and they did, wiping out comms for a few days.
Most of them you'd never know though...
