IIRC, I was a 14B (ADA-SHORAD), back in the days of the composite Vulcan & Chaparral batteries. I did stints as a platoon leader in both systems. Being a platoon leader was the most rewarding job I had in the military.
Not that Battery Commander or Battalion S-4 were bad jobs, either.
I was only lowly enlisted, but I did love doing fre missions with the M119A1 light towed 105mm.
Only time I or the crew I was with were happy was when we were doing live fire.
(We were chastised for starting "a" brush fire. Our next four rounds put it out. Nice, clean sterile ground I may add.)
