Yep, I was with the 5th Corps Air Support Operations Center in Frankfurt 1986-90.
We supported the Air Liaison Officers (ALOs) in the 3rd AD in Frankfurt, 8th ID in Bad Kreuznach, and the 11th ACR in Fulda (as I remember it).
We never had much direct dealings with the TACPs down at the brigade level. During deployments we always co-located with the Corps artillery guys, Fire Support Element I believe.
That was a good tour.
