I was with A 6/10 FA.
FADACS HO!
Yes. I was a 13E FDC and in the fall of 76 I became a 13E Recon Sgt and got to do my forward observing off of a M-60A2 tank. My battery was short one 2LT FO, so I got to spend 2 years attached to a tank company as its FO. I got to go to the field with my artillery battalion AND with the tank battalion I was attached to.
