Can you people read? The man said Special Forces. As a formed jarhead myself what I did pales in comparison to what Spec Ops people do regardless of branch of service (I support SOCOM in my civilian job and I was shocked that the airforce had a Spec Op program but they do). My daughter is considering Navy EOD right now and I took her to the EOD shop on my base and they go through some hard core stuff.
Personally I would recommend NOT hiking the trail because none of that is going to prepare you for whatever Spec Ops training you are going to have.
