I remember our M109A1, 155mm, battery going to a tank range at Graf to practice direct fire. I was a 13E, fire direction center, and was there in our M577 FDC track. I also recall many hours doing nuke fire mission calculations AND being trained to assemble those rounds.

My timeframe was 1966-70, including service as the commander of out two-vehicle armored assault *scissors bridge* section- which had more firepower than the rest of out tank battalion put together. Our MOS was 11-E[ducated]!
