When he was in Vietnam, Isaac Oxereok's small build made him ideal for tunnel-ratting: running with a pistol and a flashlight into underground passages built by the Viet Cong. In 1967 he finished his tour with the Army and returned home to Wales, Alaska. Oxereok knew he wasn't quite right, but there wasn't anyone around to tell him how to get help.

"Post-traumatic syndrome?" he said. "I went through that I guess, mostly on my own. Some wounds never really show. So inside was kind of messed up."

Myla Haider took a roundabout route to becoming an agent in the Army's Criminal Investigation Command, or CID. Wars kept interrupting her training.

"My commander wanted to take me to Iraq as the intelligence analyst for the battalion, so I gave up my seat in CID school," Haider says.

She speaks in a steady, "just the facts ma'am" tone. Once a cop always a cop, the 37-year-old says.

Dora Hernandez gave a decade of her life to the U.S. Navy and the Army National Guard, but some of the dangers surprised her.

"The worst thing for me is that you don't have to worry about the enemy, you have to worry about your own soldiers," she says.

Sitting in a circle, a group of women nod in agreement. All are veterans, most have spent time in Iraq and Afghanistan, but they're also survivors of another war. According to the Pentagon's own research, more than 1 in 4 women who join the military will be sexually assaulted during their careers.

America has been debating the role of women in combat since 1779.

That's when the Continental Congress first awarded a military disability pension to Mary Corbin after she manned a cannon in the Revolutionary War at the battle of Fort Washington in New York. Corbin got only half the pension male soldiers received, but she asked for — and received — the full ration of rum.

Today, as the Pentagon decides how to remove the combat exclusion, women still have trouble getting fully recognized for what they've achieved at war.

In a series of reports this week, NPR's Quil Lawrence looks at some of the most pressing challenges facing America's nearly 2 million female veterans. Like men, they often need assistance in finding jobs, dealing with PTSD and reintegrating into their families. And all too often, women say their military experience included sexual harassment or sexual assault.

U.S. Army Spc. Tyler Jeffries spent most of last year in Afghanistan, on dusty, hot patrols in the villages outside Kandahar. Last fall, on Oct. 6, his tour ended three months early.

"I was clearing an area and I had the metal detector. Then we had word that there was two guys coming toward our position," Jeffries recalled later that month.

At a suicide prevention center in upstate New York, America's troops and veterans are calling in for help.

And that help is needed more than ever. This past year witnessed a terrible death toll from suicide. For the first time in a decade of war, more active-duty troops have taken their own lives this year than have died fighting in Afghanistan.
