Thousands of members of the armed forces including members of the Indiana National Guard are participating in mass disaster training in Jennings County.

Exercise Vibrant Response is in full effect at the Muscatatuck training camp and Camp Atterbury in Johnson County.

More than 5,000 members of the military and civilians from across the country are taking part in the two-week, large-scale disaster response exercise. The scenario is a nuclear terrorist attack in Columbus, Ohio—and the backdrop is as close to the real thing as it gets.

About 200 medical mannequins and 300 live role players are part of the exercise– helping to train those involved.
