Excellent Christian movie!
I was surprised to see a Christian movie with such action: very realistic war scenes with tanks, machine guns, aircraft and seemingly shot in Iraq! The symptoms and impact of PTSD were realistically depicted. I now understand why some ex-soldiers do not want to talk about their war experiences.
I thought the chaplain was a bit weak on Bible and theology though: he couldn't answer very basic questions on the problem of evil ("why does bad things happen when there is an almighty and good God"). No wonder he struggled with his own faith for a while. Thankfully the basic Biblical answers to this question was given, albeit by another character.
All in all, an excellent movie from many perspectives, including good acting, realistic nail-biting action, PTSD, relationships, romance, Christian faith, apologetics, the Iraq war etc. Highly recommended, also to non-Christians.
