The United States military's ban on transgender service members faces a challenge, and her name is Kristin Beck. Beck is an author and activist who served 20 years as a Navy SEAL on 13 deployments and was once a member of the elite SEAL Team 6. She is also transgender. Beck comes out publicly as transgender in her new memoir, Warrior Princess: A U.S. Navy SEAL's Journey to Coming out Transgender, which hit stores June 1. The book describes Beck's life as Chris, a Christian boy who grew up on a farm in the middle of nowhere and became a Navy SEAL. It describes someone who everyone viewed as "a hero, a warrior, a man" but who knew deep down she was transgender.
