PLOT
An in-depth look at the armaments used in the second Iraqi war. Some are familiar--such as the B-2 Stealth Bomber--while others are profiled on camera for the very first time. Experts like Michael O'Hanlon, a senior official at the Brookings Institution, and USAF Sergeant Jay Perkins offer insights into U.S. tactics and the devices that make it possible, including the state-of-the-art defensive equipment that will protect troops from biological and chemical attack.
