Stacy Bannerman didn't recognize her husband after he returned from his second tour in Iraq.
"The man I had married was not the man that came back from war," she says.
Bannerman's husband, a former National Guardsman, had been in combat and been diagnosed with post-traumatic stress disorder. He behaved in ways she had never expected, and one day, he tried to strangle her.
"I had been with this man for 11 years at that point, and there had never been anything like this before," Bannerman said.
