CNN incorrectly reported on October 14, 2004, that the US offensive assault on Fallujah had begun and broadcast a report from a young Marine outside Fallujah, 1st Lt. Lyle Gilbert, who announced that "troops have crossed the line of departure." Hours later, CNN reported their Pentagon reporters had determined that the assault had not, in fact, begun. The "Los Angeles Times" reported on December 1, 2004, that, according to several unnamed Pentagon officials, the Marine's announcement was a feint—part of an elaborate "psychological operation" (PSYOP) to determine the Fallujah rebels' reactions if they believed attack was imminent.
