Her nick name is "mighty mouse", but her two daughters simply call her "Mom."
"Just three minutes after Hasan shot up his fellow soldiers, Munley tracked him down outside a pre-deployment facility and unloaded on him at close range.
"She fired on him twice and drew the attention toward her. He immediately spun around and charged her," said Chuck Medley, director of emergency services at Fort Hood.
"She fired a couple more rounds and fell back, continuing to fire."
Munley was hit in both legs and her wrist during the gun battle but stayed on her feet and kept firing at the charging gunman.
"She struck him a couple times in the upper torso and he went down," Medley said.
"When she rounded that corner, she made a split-second decision to put her life at risk. If she had not responded the way she had, we would have had an extremely high number of dead and injured."
Munley, a civilian cop employed by the Army, was recovering at the hospital Friday and was unavailable for comment, but she was doing well enough to take several calls from friends."
We wish her a speedy recovery - and a hefty salary increase.
Mourning the dead:
"The 13 victims of the Fort Hood massacre were flown Friday night to Dover Air Force Base, the transit point for generations of soldiers slain by foreign enemies.
Only these were victims of an enemy from within."
