A bomb dog investigates the camera during a routine patrol of a compound, Sept. 7, near Forward Operating Base Ramrod in the Maywand District. Increasingly, insurgents are using homemade explosives -- which can be as simple as buried plastic jugs packed with a deadly mix of fertilizer and fuel, and contain little metal. The keen nose of a trained dog can find the bombs that a metal detector cannot.
