Me too Sarge, I was a 13E, class of March '76.
Served with a 175mm Battery in Germany before they switched the tubes to 8". 105mm Battery at Fort Lewis and a 155mm SP Battery back in Germany. Even got to pull a lanyard once or twice :-)
Remeber the FADAC, LOL?
Charts and darts and Freddie. I switched MOS to 13B for E-7. Chief of Smoke was the best job! Loved the Hip Shoot and coordinated HE under Illum.
