The shooting happened so fast that is sounded like an automatic weapon, one soldier testified.
Some said they didn't realize they were wounded until they saw their own blood. And others told how they tried to play dead, hoping the gunman would pass them by.
The testimony came Thursday at Fort Hood, Texas, during the military's 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.
Spc. Keara Bono testified she was reading a book in the Fort Hood building, moving through the paperwork and medical tests to deploy to Iraq. Suddenly, she said, she was wounded in the head.
"At that moment, all I smelled was blood because my face was covered with it," she testified Thursday afternoon.
Spc. Jonathn Pagel said he suddenly felt a burning in his chest. "I put my hand up there and realized I was bleeding," he said.
It was hard to track how long the shooting lasted. "It seems like an eternity," he said.
And he said the shots kept coming. "It was pretty rapid, to me it sounded almost like a fully auto," he said.
By midafternoon Thursday, only the second full day of testimony, the prosecution had questioned 16 of its witnesses.
