An article entitled "Stress Found in Returning Soldiers" includes the following information: "A desperate woman wearing a black robe and her young son walked up to Alan Lewis, a United States soldier who was working security. The boy had just picked up an unexploded piece of ordnance, which blew up, badly burning his face and hands . . . Weeks later, Lewis would lose parts of both his legs after a land mine exploded under the Humvee he was driving. But his most horrible experience, Lewis said, was the sight of the boy and his mother."9 The article also found that of 6,200 members of four United States combat infantry units deployed in Iraq and Afghanistan, about 75% "reported encountering injured or ill women or children who they were unable to help." It was noted that "before the Sept. 11 terrorist attacks, an estimated 8% of Americans suffered from the [post traumatic stress] disorder."
