From the dark alleyways and desolate rooftops of Baghdad to an empty studio apartment in Clarksville, Tenn., former Special Forces soldier Dave Williams finds himself on the front lines of a new war. Unlike the war in Iraq, Dave's only weapons are his fingers and the laptop on the floor in front of his mattress.

In this dark room he sits, his experience his ammunition, and he types.

Dave's new mission is to find fakes, frauds and wannabes trolling the Internet trying to talk about something they know nothing about — The U.S. Army Special Forces.

For many of the Army's former elite, the story is the same. They have returned from honorable service in combat only to be slighted by lesser soldiers and even civilians pretending to know something about special operations. On Internet sites such as YouTube and Facebook, the former Green Berets correct erroneous comments with precision and secrecy.
