The following news release is from Entergy:
Buchanan – Entergy will be conducting security training drills at the Indian Point Energy Center during parts of the day and evening today and Wednesday, using simulated weaponry that sounds like actual gunfire.
During the drills persons near the site may hear the sound of simulated gunfire as participants carry out simulated attack scenarios. Entergy will be using a technical innovation for the exercise known as “MILES” gear, or Multiple Integrated Laser Engagement Systems.
They use laser “bullets” and vests with laser-detection equipment, and duplicate the effects, including the sound, of live ammunition. MILES gear is used for military and counter-terrorism training across the country to be as realistic as possible without using real bullets
