packbot

We hadn't even been aware that the US military was already using these there (we'd heard about their use in Afghanistan), but iRobot, the company behind the Roomba RoboVac, says that the first PackBot has been destroyed in action in Iraq. They also reveal that there are somewhere between 50 and 100 of the robots on the ground in both Iraq and Afghanistan that are being used for stuff like reconaissance and the finding and disposing of explosives. If you don't count any of those Predator unmanned surveillance drones that have been downed, could this be the first robotic casualty of war?

From titanium to aluminum to carbon fiber?
