I often wonder which Spec Operators are the baddest of the bad.
Army Rangers have more skills then the basic infantry grunt.
Army Special Forces and Delta are even more highly trained with more skills.
Marine Force Recon have similar skills.
Air Force ground controllers go through much of the same training.
CIA combat operatives ... well who knows?
They all have jump wings as far as I know. I could be out of date on that.
However, only SEAL's can wear the Trident that comes with being the first called for high risk missions. Unlike the other SpecOps guys, every SEAL is trained to perform the same duties. It's just a matter of pay grade.
I saw an interview of a member of the French Foreign Legion. One thing he mentioned having served with various allied special forces was that they were pretty much all the same.
I have also read that the most highly trained of all American special forces are the Air Force Para-Rescue.
On their mission two weeks ago, they lost their team leader to a suicide bomber. On the flight back, one of the team members began reciting the last part of the Seal Code.
It was quite compelling.
