Different from the film - A must-have

I recommend the book to anyone who wants to experience a more "intimate" by Chris Kyle and his family against its deployments in Iraq.
This means a more technical narrative, raw, hard, but more real, deeper and therefore more touching than is the film finally the best of both Hollywood standards.

4/5 stars because the translator is a fan of past simple.
So be prepared to live the adventures with unique twists
"When we arrived [...] we were surprised when we repliâmes".
This breaks the rhythm and the intensity down a bit of the story.

- Some interesting passages like the end of his contract with the Navy, or the discoveries in the field of arms French, German and Chinese for arming the "rebels" as he calls them do not appear in the film. Only Russia is cited. This raises at As questions in the minds of C.Kyle as and extent of its deployment. In the film he crosses the trials as an untouchable superhero that never arises questions.
- There are also better detailed the training phases, admission to the body of SEALs, life at camp (not unlike the film Jarhead), compared with the military hierarchy, the point of view of ground troops (the limit of indoctrination matter).
- We are faced with failures in certain deployed on the border of the comic. This gives an interesting aspect of the effectiveness of information and mission preparations.
- We do not find the "villains" are the red thread of the film: the butcher and the sniper medal of the Games. 1 is not mentioned. C.Kyle said he never faced the second. His shot record is at 1900m. Clint Eastwood has seen fit to put in the scene end 3600m. Why? It's almost a shame to have done too. Especially since C.Kyle always seems to keep modesty and distance to his actions on the field.
