Don't think this book is only for servicemen and women. Sure, there are stories of actual combat experience in Iraq. But Mark uses his and his fellow soldiers' experiences as teaching moments on what it means to be a Christian and how to apply the teachings of Christ. And not just in combat but in our everyday lives as well. We all have our challenges, although not necessarily as harsh and demanding as combat, but everyday challenges can come up against our beliefs, our faith. Whether deployed to a combat area, or deployed to our jobs, school, or anywhere else where we come up against "life", this book will teach you how to meet those challenges while maintaining your faith.
As a note, I know Mark very well and I know his background and family. And I can tell you that they don't just preach the gospel, they live it every day and every hour of every day. Mark did not come home from Iraq with a new faith in Christ, he was raised with it, took it with him, then returned with his faith intact.
