Aberdeen testing center aims to improve armored vehicles

As Army Col. John Rooney pointed out features on five armored vehicles being tested at Aberdeen Proving Ground, an experimental cannon fired in the distance with a thunderous boom.

Rooney points in one direction where several miles away a submarine was being tested, “and that’s all I can tell you about that,” he said. He points in another direction where a series of hills tests the drivetrain of all military vehicles.
