To get in SOF you gotta be one smart dude... at least for the US, I had a 93 average and you need 85 I believe. I learned everything I needed to know before taking the tests, but they all are so hard. Gotta be in active service for about 10 years I think now, or graduate on the top of your classes and you can qualify. Now we all know the main part is the physical. DUDE! all I gotta say is "Hell Week" the worst experience you'll ever feel, see, smell, and even hear. youtube "hell week" I think they did something on it. Just remember whatever you see in videos it's 1000 times worse man.
Frostbite, Thats pretty sweet man. I've always wanted to do SWAT, it takes a lot man. Got to be on the force for 5 years minimum, thats why I never did it. Can't stand being out on the streets in my ghetto neighborhood. Best of luck bro and let me know how it goes.
