For anyone interested in knowing how to prepare you mind and body for elite military selection, this is the book.  Here’s a description from their website.

For the past 10 years, we have trained people for the toughest SOF selection courses in the world. We’ve trained candidates for courses in every branch of the U.S. military, as well as five other countries, including British SAS selection.

Our clients have a 90% success rate which means 9 out 10 people make it through. (BUD/S and SFAS have drop-out rates ranging from 60-90%, FYI.)

In the book, we give a detailed look at our SOF training system – from big-picture principles to practical exercises and programming guidelines.
