For the third time in our century, the Navy and Coast Guard arc cooperating in an interdiction effort at sea. During Prohibition, the Coast Guard attempted to stifle the efforts of the "rum-runners." To help out, the Navy loaned the Coast Guard more than a score of destroyers from its large fleet of idle warships. During the Vietnam war, Coast Guard cutters and patrol boats played a major role in the Navy's Operation Market Time off the South Vietnamese coast, an apparently successful effort to frustrate enemy shipments of munitions to the Vietcong.
