What's up with the military?

So, my brother Dimitri got a call last Sunday telling him he was going back to Iraq. The problem is, is that they said he had to leave last Wednesday. Really, really?? So, he's leaving his family, friends, girlfriend, etc. and they give him less than 3 days to say goodbye, pack, put everything together. Don't get me wrong, I think what were doing in Iraq is good. But, common, give a guy more than a short 3 days notice before he goes to Iraq for over 6 months. I think that's pretty darn ridiculous!
