The deadliest buzz

In the Sunday Times today there is a review by Max Hastings of a new book about the war in Afghanistan. The book is 'Desperate Glory: At War in Helmand with Britain's 16 Air Assault Brigade' by Sam Kiley. The review starts by saying there is a one in ten chance on a British infantryman in Helmand suffering death or a life changing injury.
One in ten????
Yet Sam Kiley says in his book that almost every front line soldier he has met is loving the war. 'They are getting to play the most exhilarating and dangerous game man as ever invented - the original sport.'
Whaat? Is this true?? Is this really what men on the front line think?
Sam goes on to say that it is part of the basic male instinct , the army takes the instinct, nurtures and refines it. apparently one in three members of one unit which Kiley was attached was killed or wounded.
One in three???? What is the point? The book admits that the war is unwinnable. What are we doing to our young men and their families? The original sport? I'm sure these young men can get a buzz and adrenalin rush in other, less devastating ways.
Elsewhere in the paper today there is a heart-rending piece about a young army wife left with two small children. The article details how the wife felt when the two officers arrived at her door to tell her that her husband was dead. She says she felt that if she didn't open the door, then the news wouldn't be true. Another sad tale. The real life story that carries on - once the young men have completed their part in what Kiley calls, 'the greatest adventure on earth'. Women and children, young families left only with grief and memories. Tragic.
