Testifying Wednesday afternoon, Spc. Amber Barr described how she and her buddies ran for their lives when the shooting began.
"I saw there was blood. I smelled sulfur in the air and I realized it was not a drill," she said.
"It was absolute chaos," she continued. "People just trying to shield themselves from the gunshots."
Barr said she and others managed to get outside and she helped half-carry, half-drag a friend to a nearby pick-up truck which took them and others to the Fort Hood hospital. It was only then, when she tried to sit down, she realized she herself had been shot in the lower back, she said.
Spc. Matthew Cooke told the hearing he was shot four times but was so charged up on adrenaline he didn't realize he had been wounded. He still carries bullet fragments in his body.
The military is holding an evidentiary hearing into the case of Maj. Nidal Hasan, who is accused of the Fort Hood shootings last November that left 13 people dead and dozens wounded.
