Quote from : Post-Deployment Wisdom For Those Expecting A Returning Service Member Book

There are two things a combat deployment offers which all of us strongly desire. The first, being purpose. Every morning we woke up and knew why we were there. It is immediate and unavoidable. Although, it is extreme and unpleasant, there is a comfort in that purpose. The second, is simplicity. We have one goal. There are relatively simple rules on how to accomplish it, and we understand that just about everything will go wrong. Pretty simple.
