A lot of people try to G2 a course. Honestly, whilst I was back at my original home station, the only thing I "G2'd" was the best physical training schedule to use for me specifically. I asked everyone and anyone who had gone and made it, or not, how they prepared. I sent away for a copy of the SAS Selection physical training manual (I forget the name. It was a small black book that I think is out of print now), the SFAS booklet, and the CCT/PJ Course book from Five Stars publishing. I got a good friend, who was also a "stud" physical fitness guy, to coach me on speed and distance running. Then, I spent the next three months working myself to the best shape of my life. I rucked, ran, swam and lifted weights every week. I prepared for the worst case scenario.
My idea was that if I got significantly hurt, only peak physical fitness and intestinal fortitude would see me through. I think this is the only way to "G2" the course. If you are trying to find the answers to "cheat" your way through, then, chances are that you won't make it past selection. If you do, chances are that you won't make it past the Q-Course. If you do, chances are that you won't make it past your first year in a team. New guys being fired from a team for not cutting it is not new. In fact, I just fired a guy last month from my team for the very reason. Accross the hall, another guy not only got fired, but got his SF tab taken from him. If you are trying to G2 for the wrong reasons, the "Regiment" will find a way out for you.
PS - That's the "1st SF Regiment" for those of you that don't "habla"... "comprende"?
