A U.S. soldier serving in Afghanistan has become a media sensation after he was photographed fighting Taliban forces while stripped down to his skivvies. Army Spc. Zachary Boyd, 19, who hails from Fort Worth, Texas, said he was in his sleeping quarters at Firebase Restrepo in the Korengal Valley of Afghanistan's Kunar province when the Taliban attacked, forcing him to take up a defensive position while clad only in his helmet, protective vest, a T-shirt and his pink "I Love NY" boxer shorts, the Fort Worth Star-Telegram reported Thursday.
