Another US study recently pointed out that Savannah, Georgia, the port through which the US Central Command would deploy to a war zone elsewhere in the world, could be paralysed by an information warfare attack on just one building, which contains the computers controlling the traffic system, communications and electric power system.

The report points out that all current US military doctrine assumes information superiority.

Information superiority will be paramount for the United States to respond to all future conflicts, military officials said.

The value of information superiority was clearly demonstrated last year in the U.S. action in Bosnia, said Gen. Richard Hawley, commander of the Air Force's Air Combat Command.

The idea is to gain information superiority — "to out-see, out-think and out-shoot them," said Francis Cevasco, U.S. deputy undersecretary of defence and director of the Defence Department's North Atlantic Treaty Organization/European affairs office.
