Public awareness of the US military's information operations is low, but it's growing - thanks to some operational clumsiness.
Late last year, it emerged that the Pentagon had paid a private company, the Lincoln Group, to plant hundreds of stories in Iraqi newspapers. The stories - all supportive of US policy - were written by military personnel and then placed in Iraqi publications.
And websites that appeared to be information sites on the politics of Africa and the Balkans were found to be run by the Pentagon.
But the true extent of the Pentagon's information operations, how they work, who they're aimed at, and at what point they turn from informing the public to influencing populations, is far from clear.
