Improvised Warfare In Iraq Leaves Lasting Effects

Army Sgt. Maj. Todd Burnett spent about three years in Iraq hunting for improvised explosive devices, also knows as IEDs.

"I can remember going out and one week I got blown up three times," Burnett says. He says back then, it wasn't whether you were going to get blown up, it was just a matter of when you were going to get blown up.
