After re-reading this new book I returned to the author's previous ones. I recommend "Breaking the Military Covenant - Who Speaks for the Dead?" to all servicemen. It's a work of amazing depth and breadth and available free on Kindle Unlimited. Judging by the blurb on Amazon there were problems with a publisher, so you need to get this title, not the unofficial one.
Also, if you pick up BBC Scotland there's a new documentary about the Chinook crash on Wednesday at 2000. Part of a series "Disasters that shocked Scotland".
