Marine and Sgt. Dean Bennett survived several combat tours in Afghanistan and returned with PTSD and a traumatic brain injury. Sgt. Bennett shared with CBS 6’s Brendan King how fireworks used to impact him. “When I first came back [from combat], definitely the explosions, the crackling, the popping. It used to get my heart rate up my anxiety up a little bit,” he recalled. He described hearing fireworks easily taking him back to the terrifying war zone.
