Hi Frank,
You mentioned Hanau in the other thread, so I think this might be the base you're thinking of (left column, bottom paragraph, mentions artillery too):

From the sound of it, "Fliegerhorst Kaserne" has been adopted by the US forces as name for the installation, which would be a perfect fit for your description. (And prove my above post wrong at the same time
Here is a link to the USAAF chronology for December 1944:
USAAF Chronology:
Hanau is mentioned as 8th Air Force target:
"378 B-24s are sent to hit the Hanau (270) and Aschaffenburg (69)
marshalling yards; 17 hit the secondary, Gelnhausen and 8 hit a last resort
target, the marshalling yard at Friedburg; 3 B-24s are lost and 45 damaged;
11 airmen are KIA and 20 MIA. Escorting are 193 P-47s and P-51s; 1 P-47 is
damaged beyond repair."
I hope that is of some use to you, though the participating units unfortunately are not mentioned here.
Regards,
Henning (HoHun)
