Navy Secretary Ray Mabus said the Navy will conduct random blood-alcohol tests on its sailors in the United States starting next month, a sign of how concerned the service's leaders have become about the effects alcohol abuse is having on the force. The tests are part of Mabus' 21st Century Sailor and Marine Initiative, an expansive program intended to improve the well-being of sailors and Marines after more than a decade at war.
