What you don’t know going in is that when you come out, you will be scarred for life. Whether you were in for a week, a month, or a year—even if you come home without a scratch—you are never, ever going to be the same.When I went in, I was eighteen. I thought it was all glory and you win lots of medals. You think you’re going to be the guy. Then you find out the cost is very great. Especially when you don’t see the kids you were with when you went in. Living with it can be hell. It’s like the devil presides in you. I knew what I sighed up for, yes, and I would do it again. But the reality of war—words can’t begin to describe it.
