A former U.S. Navy SEAL has announced she is now a woman. Kristin Beck served as a SEAL for more than 20 years as Chris Beck, where she was known as a "consummate guy's guy." Anne Speckhard, co-author of Beck's new book, "Warrior Princess," says that Beck "really wanted to be a girl" since childhood but felt that she couldn't make the change while she was a SEAL. After retiring in 2011, Beck decided it was the "right time" to "make [her] body match [her] identity."
