Those who serve in our military go through rigorous training and elite forces must reach even more difficult standards. Perhaps the most famous and most demanding training belongs to the U.S. Navy SEALS. Candidates are tested physically and mentally in many different ways over many months but perhaps the most intense crucible is Hell Week.

In this edition of "Veterans Chronicles" author Scott McEwen joins us to discuss his new book, "Hell Week and Beyond: The Making of a Navy SEAL." McEwen takes us moment-by-moment through six excruciating days that expose the candidates who truly excel and never quit and those who don't quite measure up. From fighting through pain and sleep deprivation to hypothermia and sickness, McEwen explains why SEAL candidates go through Hell Week and how it creates a lasting brotherhood among those who endure.
