Whne I was stationed at Baumholder, GE several of the firing points where off post. I remember sitting our behind the BOQ's drinking beer and watching the rounds come in from south of the post and asplody in the impact area on the MTA.
(we could also watch them shoot teh various Tank Tables on range 35.)
We had two former battery commanders serving as OIC's of the Golf course. One after his FDC computed weather data at like 3am and they didn't shoot until 3pm. Rounds impacted off post in a farmers field.
The other had his one of his FO's announce over the radio "DID NOT OBSERVE, REPEAT". While Range 4 (100m Rifle Range) was screaming (in a very panicky voice) on the Range Control freq "CEASE FIRE, CEASE FIRE, THIS IS RANGE 4, I HAVE ROUNDS IMPACTING ON MY RANGE, CEASE FIRE!!!! CEASE FIRE!!!!" That was bad math on computing the charge. I remember CID joking that "They forget to carry to the one."
And yep this was back in late '80's early '90's. We had German Civilians that worked the ranges. (Target setup, maintenance, etc.)
