America's biggest military base is a tight-knit community. In the aftermath of mass murder by an army psychiatrist, many feel the horror and trauma of war has invaded their homes. Paul Harris reports from Fort Hood, Texas
Private Marquest Smith thought the first sounds of gunfire sounded like popcorn being cooked. It was only when people started to scream that he realised what was going on.

As bullets flew he then got up and shepherded people in and out of the building while the bodies piled up. He thought it was a dream. War was something that happened overseas, not in a military base that seems more like a small city than an armed camp. He described his thoughts to the Observer. "I thought: 'Are you serious? Is this really happening?'"
