What it's actually like in the real Situation Room, as described by the White House:

PictureInside the Situation Room
"There was a time that the Situation Room was known not as Wolf Blitzer's evening newscast, but a nerve-center of information for the President of the United States. Created by the Kennedy Administration in 1961, the "Sit Room" serves as a conference facility, a processing center for secure communications, a hub of intelligence gathering, and a center for emergency operations. It's staffed by men and women from the Department of Homeland Security, the intelligence community, and the military, all of whom are committed to ensuring that the President of the United States is provided all the information and intelligence he needs to do his job."
