Praying is an excellent thing. But if you would like to do more for the young men and women in Iraq and Afghanistan, go to Michael Moore's web page. He has a whole listing of organizations that are set up to help service people and their families.
Most of these people went into the service to get money for college, or extra money to pay the bills, or training in a specific field.
When I was a kid, someone put a sign up sheet on the school bulletin board asking for radios to send to soldiers in Vietnam. I had a little transistor I never used, so I signed up. As I as doing so, a passing classmate punched me in the eye. She played goalie on the hockey team, so it was a good punch.
Most of those kids were draftees, who didn't have any real choice, except jail.
