The events played out in Grafenwöhr (Grafenwoehr) West Germany during the summer of 1966. Grafenwöhr was a major training area for N.A.T.O. forces and located close to the Czechoslovakian border.
The story is told here in the witnesses’ own words:
“I was in the weapons platoon of a rifle company in the (U.S.) Army. The weapons platoon was made up of four armored personnel carriers, which were 13-ton, lightly armored, tracked vehicles [M113]. Three of the APC’s were 81mm mortar gun crews, and the one I was in was the fire directions center. I was a driver at the time.
