There was a thread on here years ago where a tube artillery outfit at Ft. Hood somehow got 180 degrees out on the azimuth during a night fire exercise.
More than one projo landed in some guy’s back 40 a few miles off post but I don’t think anything was damaged.
(Other than some folk’s careers).
I wisht I had a nickel for every time the Massachusetts National Guard at Otis shelled the Cape Cod canal due to an azimuth error. They don’t fire artillery there anymore. I spent 16 weeks in Sill, and the folks around the base used to complain about the thunder. Where I live now is a few miles from (Fort) Devens, and when the Army did artillery drills there, you hear and feel it for miles.
