Query: Dirty little secrets....

You won't care you know.... There's nothing in this book that qualifies as a 'dirty little secret'. "Dirty Secrets" are supposed to be titillating, shocking or at least something you can't find out by watching the History Channel for an evening. This book would have been better off titled "Boring Things About the World's Military" or "I Wrote a Book of Facts! Aren't You Impressed Yet?"
