Was looking through my unabridged Audio Editions catalogue. Found this: Shooter: The Autobiography of the Top-Ranked Marine Sniper. Author: Gunnery Sgt. Jack Coughlin, USMC, et al. Reader: Dick Hill. Uabridged cassettes $29.95 also in CD and MP3-CD. More info: www.audioeditions.com
It's not my cup of tea, but thought I would pass it on.
