breeching the doors to get in, the demolitions, explosives, mechanical breaching, being able to get into anywhere, fight your way up multilevels, down multilevels and clear a building and get out. so when i heard that, there was no doubt in my military mind it was s.e.a.l. team six. >> it's hand picked from other s.e.a.l. teams. you get into the s.e.a.l.s first and they select other people for s.e.a.l. team six? >> exactly right. i was with s.e.a.l. team two and i put in my application for s.e.a.l. team six. you go in front of a review board and they evaluate you, and then you go to six, but you're not there to stay. you go through a green team. it's a selection course. you go through a green team and when you make it through that, which is more highly intensified training, then you get to become a s.e.a.l. team six member. >> how tough is the training?
