Staff Sgt. James Adams, 366th Civil Engineering Squadron Explosive Ordnance Disposal craftsman, shows the word "EMPTY" that has been stamped on the Civil War round which belongs to Dianne Judd-Wade, speech-language pathologist for the Cascade Public Schools in the Mountain Home Air Force Base EOD conference room, Mountain home Air Force Base, Idaho, Oct. 25, 2013. The projectile was picked up off a Civil War battlefield by her great-grandfather more than 150 years ago and passed down through the family throughout generations.
