She was also so immature she sounded like and spoke like a 10 year old. She was apparently extremely unhappy, wanted to go back to the States, kept a teddy bear with her, and sounded similar to the way many people remember their kid sisters sounding around the 5th or 6th grade.
It was spooky. It would almost seem she had regressed psychologically, was living in a netherworld, not really solidly in touch with reality. She spoke of people shooting prisoners waiting to be fed with complete detachment.
She had begun throwing rocks at prisoners as she was getting revenge for their pitching rocks at the troops.
At the end of the segment, she was simply close to babbling, as if she only wanted someone to know how much she wanted to get out of there, and was trapped behind barbed wire, also, just like the prisoners. Clearly it was too much pressure for her mentally.
On edit:
We're in luck if you have Real Player! CBS already has the video available online which has the segment showing the soldier in question! Go here:

I just checked to make sure it works, and it looks like the story they did tonight.
