I don't know Coughlin personally, and only met his compadre Kuhlman once, but the exploits laid out in the book often came at the expense of other things. Specifically, there were primary duties that the dynamic duo of Coughlin and Kuhlman were supposed to be executing. None of them involved roaming around as their own sniper team.

The antagonist character in Officer Bob couldn't be further from the truth, but I guess that's Coughlin's perogative when he writes a book about himself. We don't get to hear about what he should have been doing, because I guess that's not sexy enough.

Not directed at you Culpeper, but Shooter is the modern Bravo-Two-Zero. Heavy on fiction, or at least half-truths.
