The U.S. state of Georgia recently hosted the massive Vigilant Guard 17 part 2 exercise (Vigilant Guard 17 part 1 was held in California & Nevada at the end of 2016):

The exercise is promoted as preparations for natural disasters, however our leaders must be expecting a massive catastrophic event because Vigilant Guard 17-2 included the United States Northern Command, U.S. Coast Guard, National Guard Bureau, Georgia Department of Defense, Georgia Emergency Management and Homeland Security Agency, South Carolina National Guard, Kentucky National Guard, Florida National Guard, Tennessee National Guard, Virgin Islands National Guard, and included preparations for a Chemical-Biological-Radiological ‘event’!
