Ok. Heres the thing, was your grandfather in Battery "A"? If so, with Battery " B" the only battery section being assigned to a division then the only unit he belonged to was the Corps. Level Artillery the 997th. He has no affiliation to the 69th Division only those of Battery "B". He'd have been back in his unit attending to whatever was asked of him from his battery commander or his commanding officer.

You see during WWII An Artillery Battalion was comprised like this:

Battalion Headquarters
"A" Battery
"B" Battery
"C" Battery
"D" Battery

Now there is a potential for an "E" Battery I have seen them but, its not that common, your probably real safe with just the four batteries.

So if only "B" Battery was assigned everyone else was up at Corp. level doing whatever it was they were assigned to do on an everyday basis. Also whe he arrrived he arrived witht he 997th FA Bn. and was assigned to whatever Corps. he was assigned too.

Each battery didn't have a motorpool, they'd of had a battalion motorpool.
