For the first time, women are joining the U.S. military's elite commando units. They're still not allowed to serve in front-line combat units, but they can go into secured compounds in Afghanistan and help villagers after raids. Their role is critical: They're providing help for Afghan women, and searching them for weapons - something male soldiers struggle to do. The training is rigorous, and the troops are determined. "It's being sort of acknowledged that women can operate at this level," Army Staff Sgt. Danielle Bayer said.
