Suicide killed more American troops last year than combat in Afghanistan, and that is likely to be the case again this year.

According to the Pentagon, there were at least 349 confirmed suicides in 2012, compared with 310 U.S. combat deaths in Afghanistan in the same period.

Howard Lincoln of White Mountain, Alaska, doesn't always hear it when people knock on his door. He's 82 and he still has a little shrapnel in his jaw from a mortar shell that nearly killed him in the Korean War 60 years ago.

"We heard it whistling, but I was the third one in line running toward the bunker," he recalls.

Wounds to his face, arm and hip laid him up in a Tokyo hospital for quite a while. But he recovered, came home to Alaska in 1955 and says he never applied for Veterans Administration (now the Department of Veterans Affairs) benefits.

Alaskan Clyde Iyatunguk grew up hearing stories about the U.S. Army colonel, Marvin 'Muktuk' Marston, who helped his father trade his spear for a rifle, to protect his homeland during World War II.

Marston is a household name with Native Alaskans. The nickname comes from an Eskimo eating contest — muktuk is whale skin and blubber, eaten raw.

After the Japanese reached the Aleutian Islands in 1942, Marston traveled by dogsled across Alaska looking for volunteers who knew how to fight and survive in the Arctic terrain.

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.
