A chaptered story told on many blogs starts here and continues here:

Chapter 11

Chapter Twelve: Great Americans
We have a great team assembled at my FOB, which could be considered unusual. My commander didn’t get to hand-pick his team, whether the members that came from our parent unit or the various attachments, some of which came from within our brigade and others from Reserve units or even other branches. The guys here take their jobs seriously and many take the initiative to find ways to support the mission despite an occasional lack of support or other challenge that may keep us from using “conventional” means to get the job done.
I am excited to have had the opportunity to serve in this position. I have grown professionally because of it. More than I thought I would, which is an unexpected surprise. I am a lucky man in this respect.
I would like to thank the folks working here at FOB X with me. These are truly great Americans. I look at all these troops and am amazed, not only at the tremendous effort they put forth under crazy conditions sometimes, but also because these are people that could be doing anything but putting their lives on the line for Iraqis. And yet, here they are, volunteers each and every one, working hard, sweating, laughing, crying, sometimes bleeding for something that is beyond day-to-day comprehension, something that transcends the individual and actually makes a difference in our world. I am privileged and honored to serve with such selfless and open-hearted people.
The irony is not lost on me either, how we are ready to kill those that would threaten us but we are dedicated to making life better for normal Iraqis who just want a taste of what many Americans take for granted: freedom.
