Six soldiers at a Georgia Army base are being hailed as heroes for tackling an armed assailant accused of shooting five people. Officials say Sgt. Quornelius Radford used a personal handgun to shoot five soldiers Wednesday at Fort Stewart before being tackled by other troops. Army Secretary Dan Driscoll praised the soldiers' quick actions, saying they saved lives. The wounded soldiers are stable and expected to recover. Sgt. Aaron Turner said he was helping lock down a supply warehouse on Fort Stewart after gunshots were reported in a neighboring office building. Then he saw a fellow soldier walking past, wearing a hooded sweatshirt over his uniform and holding a handgun. Instead of ducking for cover, Turner said, he approached the gunman and started talking _ asking what he was doing there, and where he was heading. When he got close enough, Turner grabbed the soldier's gun and took him to the floor, holding him until military police arrived. “Pretty much my training ended up kicking in," Turner said Thursday. "It wasn’t about my life at that point. It was about the soldiers.” The suspect was arrested and officials are investigating the motive. This incident raises concerns about safety on military bases. The FBI is assisting with the investigation.
