All political opinion aside, all views of "wrong and right" aside, this is a cracking account of young men in real combat, an account of the Royal Anglians tour of Afghanistan.
And because of that, it is obviously very pro British, pro NATO coalition, and glorifies the conflict to some extent.
But go past all that and hear the stories of these kids under fire, watching their mates get blown up, killing another human being for the first time (or hundredth time) getting bombed by their own allies and to what extremes they go to to help a comrade, and you might get a glimpse as to why so many of these troops come home and struggle to fit back in with our "normal" life.
