From the Soldier side: I just came across a blog that I put on my list. If you want to see and read about somebody how has really big balls, check out http://ward57.blogspot.com/
I was a Combat Engineer many years ago. We built stuff and blew things up. We got to work with explosives from time to time. I loved it. It was too scary for some. I recall in my Engineer course, on the day we were actually going to go blow holes in the ground....most of the students were a little shy. Our first charge was only 2 pounds.....prep the charge, cut the time fuse, put the cap in the charge, tape it up, pull the igniter...walk away. Boom!
After the first blast, about half the students developed a great respect for explosives. When we went to set the next several charges in the hole, fewer and fewer students walked down range with us. By the time we set the last charge of the day, there was one other student, the instructor and me. Everyone else seemed to be a little shy. It is not at all like TV and the movies. You don't have time to run. Det cord "burns" at 27,000 feet per second. Most explosives "burn" around that speed...it's not really burning, it's exploding...can you run that fast? An M-16 bullet goes a little over 3,000 feet per second.
Now...keeping that in mind...think of an Airmen, Soldier, Sailor or Marine dealing with a bomb or mine that some other asshole has put out in the field. Now, you have to go make it safe. I learned 20 ways to booby trap a mine...so bad I couldn't even disarm it if I had to.
Write this down. Anybody who works in EOD for a living has the biggest balls in the world. You will have a hard time finding anybody with more guts.
