New Secret Weapon?

Does the U.S. government have a new weapon that is a military leap forward akin to the introduction of the tank and the airplane in the last century? Bob Woodward said so much on 60 Minutes last Sunday, telling us the weapon was a yet unknown key to the improved security situation in Iraq, but he refused to elaborate. We still don't know enough to evaluate Woodward's extraordinary claim, but today's Los Angeles Times provides a better description of what he was alluding to in the interview.  At least part of the secret is a car battery-sized device attached to a predator drone used to identify and target individuals even while indoors:

But officials said the previously unacknowledged devices have become a powerful part of the American arsenal, allowing the tracking of human targets even when they are inside buildings or otherwise hidden from Predator surveillance cameras. Equally important, officials said, the systems have significantly speeded up decisions on when to strike. The technology gives remote pilots a means beyond images from the Predator's lens of confirming a target's identity and precise location.
