I was damned good with a map thank you very much!
Now, property accountability.....
Our battalion had batteries at Hahn, Spangdahlem, and Bitburg AB's. My first two years were with C Battery at Hahn, my last two were at Battalion HQ at Spangdahlem. I was in the S-4 section for much of that.
I knew most of our area of operations like the back of my hand by the end of my third year, to include the "alternate supply points", i.e. gasthauses and backereis. I was sought after during evaluations...by the evaluators looking for the best places to visit.
