The Hero Who Stopped the Shooting

She is a civilian police officer, and Mary Katharine Ham provides more information:

Her name is Kimberly Munley:

Army officials say the suspect, "the lone shooter" for this tragic incident, Maj. Nidal Malik Hasan, is currently on a ventilator at a nearby civilian hospital and the police officer who gunned him down, Kimberly Munley, a civilian Fort Hood police officer, is in stable condition.

She's a civilian officer:

Munley, who had been trained in active-response tactics, rushed into the building and confronted the shooter as he was turning a corner, Cone said.

"It was an amazing and an aggressive performance by this police officer," Cone said.

Munley was only a few feet from crazed Army psychiatrist Maj. Nidal Malik Hasan when she opened fire.

Wounded in the exchange of gunfire, Munley was reported in stable condition at a local hospital...

Cone said Munley's aggressive response training taught her that "if you act aggressively to take out a shooter you will have less fatalities."

"She walked up and engaged him," he said. He praised her as "one of our most impressive young police officers."

Just like the female security officer who confronted the church shooter in Colorado Springs awhile back, this lady charged in and got the job done. No telling how many lives she saved.
