Tank, sub maker tapped to guard US-Mexico border By PAUL BEDARD

Tank, sub maker tapped to guard US-Mexico border:
One of the nation's biggest defense contractors, known for building tanks and nuclear submarines, is being tasked to deploy its latest surveillance equipment along the U.S.-Mexico border in one of the first moves by the administration to add eyes in its war on illegal immigration. The Department of Homeland Security and Customs and Border Patrol said that General Dynamics has been approved to pepper the border with its 80-foot-high sensor and video system that directs the Border Patrol to illegal traffic detections.
