There is some chat over on a couple of forums that SOF guys hang out on that states her passing SFAS was ordered to happen. I know I've read multiple statements saying she was a 21 day non select who failed key portions of SFAS.

When I went to SFAS out of around 250-260 people 56 finished and 52 were selected. One kid who finished was a physical stud, but they thought he was too young so they told him to come back in a couple of years.

I know for me coming from a Cav unit all the ruck marching was murder on my feet. The infantry guys in general seemed to do pretty well. No matter who you were team week was a MFer.
