Palo Alto, California (CNN) -- It wasn't until five months after Army Staff Sgt. June Moss returned from the Iraq war in 2003 that her real battle began. The horrors of the war -- witnessing decapitated and burned bodies amid mass destruction -- led to post-traumatic stress disorder.
"I do notice when I'm stressing out that I start having dreams about what I saw and how I felt," says Moss, now 40 and retired from the Army. "It does come back as if to haunt you."
The percentage of women in the military has doubled in the last 30 years, with more than 350,000 serving as of 2009, according to the Department of Veterans Affairs' latest figures. With more female troops in combat, there has been an increase in PTSD diagnoses: One in five female veterans suffer from PTSD, according to the VA.
