PORTLAND, Ore. - With the end of the Iraq war, many soldiers are asking themselves the same question.
Some soldiers are looking for work, or just trying to figure out how to deal with life after war.
Oregon National Guard Captain Daniel Faust knows all about the challenges of returning from war to a normal civilian life.
Faust served as an engineer soldier in Afghanistan, where he says his unit helped build roads and a school.
He returned to Oregon a few days ago and hopes to find work in the next 3 to 6 months.
He said he was told the National Guard was cutting back and couldn't afford to keep him active in Afghanistan. Faust says he wanted to stay because nothing will measure up to his service.
"Where else in the job market can you go and know that you are going to change people's lives every day? By being there, by doing something," said Faust. "You're going to change that person's life. You're going to improve it from what it was yesterday."
Faust says his favorite picture from Afghanistan shows a little girl, not more than 5 or 6 years old, carrying water bottles he gave to her father.
Clean water that was very hard to come by where they lived.
"I made a difference in that person's life," said Faust. "There's no way to explain how much of an impact you can make except for the picture of that little girl."
