How's life being in the US army?

Well, he has joined the Army and must serve in whatever capacity that the Army needs him. I will be going to Iraq myself and I am not worried. You have to remember that the media only reports deaths and losses, they are not reporting the good things that are happening over there. Also, the statistics are actually very low. Don't worry and just support him and be there for him. He'll be back before you know it!
