I found these videos of the current training for nuclear terrorist attack going on in Indiana's Camp Atterbury as part of the Vibrant Response exercises. It is a little interesting that they chose to show the part of the exercise where they have to deny people help, food or water. I guess denying help is an important part of U.S. disaster preparedness training. These exercises train the response to Northcom's "annual big exercise that will replicate a detonated nuclear weapon in a major metropolitan city." It may just be military jargon, but the Lt. Col. interviewed talks of "launching operations against the city," perhaps just an odd choice of words.
