A very good friend, who is now a DJ on a regional rock station, was a seal for 4 years during Viet Nam. The stories are unbelievable, but true. out of 100 applicants, 5 are accepted and only 1 on average finishes SEAL training. Some of the underwater explosives take up to 3 minutes of holding your breath to install. Try it. I can't see how it's humanly possible for some of the shit these very special people are able to achieve. There was a special on DSC a few years ago which we watched together. He told me they down played alot of the more nastier things like eating grubs, bark, silent killing, bloodless noiseless killing. Like I said, special men for a specail job.
