No way - I cannot agree with the argument that we should EXPECT massive over-embellishment in 'non-fiction' books just to make a good story. The occasional white-lie or half-truth may be acceptable for continuity/protection of the innocent but to invent 250 dead Iraqis is taking it a bit far, if that is what is inferred. Authors should tell the truth, accepting that life isn't quite as action-packed as a hollywood movie, or label the book 'fiction'!
However, and in my humble opinion, the accounts of B20 are full of tragedy, courage and triumph over adversity; even without the alledged elaboration, they would have been best-sellers.
At the final count however, I tend to agree with the sentiments already expressed that the 'Hereford Book Club' episode (including de Billiere) has, by and large, served only to tarnish the reputation of The Regiment and its silent majority. The only recourse for them and the MOD is to stay well clear of the issue.
The public, of course, are desparate for SF stories/info. But the less that is known, the better because the aura of mystique is what keeps the chaps 'special'. They certainly scare the pants off me!
