when the Field Artillery started using computers, some of the firing errors would shock you.
I was doing a FTX once and we got to actually call in artillery. Now, I've never had problems figuring out where I am on a map, and on previous exercises I was always able to get the round on target with only 2-3 adjustments.
Got into an arguement with out FO, who swore that our positions was five clicks from where I said we were. Needless to say, the ole E-5 got out voted by the 1st Lieutenant. And we used his grid coordinates to call for fire. As he was completing his fire mission, I had dismounted from his M-113 and stepped into an old foxhole, and was pulling on my kevlar. About the time our Lieutenant finished saying "Get your ass back on the track now Sergeant!" We heard the whistle of incoming artillery. The spotting round struck less than 40 meters from our track.
As you can imagine, the FO was back on the radio screaming "CHECK FIRE! CHECK FIRE!"
And I sat in the foxhole, grinning at the Lieutenant....
