ABERDEEN PROVING GROUND, MD - AUGUST 24: A Category I (L) and Category II Mine Resistant, Ambush Protected vehicle (MRAP) drive through an off-road course during a demonstration at Aberdeen Proving Ground on Friday, August 24, 2007 in Aberdeen, Maryland. According to the Department of Defense, the MRAP vehicle's v-shaped hull and raised chassis has proven to protect troops from improvised explosive devices (IEDs), small-arms and mines. Siting problems with delivery, the Pentagon said it will fall short of its goal of sending 3,500 MRAP vehicles to Iraq by the end of the year. (Photo by Chip Somodevilla/Getty Images)
