I read a novel several years ago, called "The Devil's Footprint" by Victor Flynn. This novel has quite a bit of action in it, including a terrorist attack on Ft Bragg, and a combat jump by the entire 82nd Airborne Division into a giant terrorist training camp in Mexico.
Sounds great I know, but the book is kind of poorly written, with unrealistic characters, and wasn't quite as good as I had hoped.
Anyway, to get to the point, there is a vehicle mounted weapon used in this book that I have never heard of since, although I have searched the internet for it several times.
It is called (in the book) 'Dilger's Baby', and it is a single 30mm barrel removed from the GAU-8 Avenger cannon of an A-10 Thunderbolt. Fitted with a six round clip, it is mounted on dune buggies and other very light vehicles to give them anti-armor punch.
This system sounded pretty dang cool to me, but I don't know if it is real, or a figment of the author's imagination. Any ideas?
