I was an ALO at Ft Hood decades ago. Our building had no elevator. Like you, I can’t remember many that did. Hospitals, maybe. And I was Air Force, where we paid lip service to physical fitness! I do remember mandatory running at Ft Hood...wonder if they still do that!
The Air Force got into running around 2003, and fitness is a much bigger part of the culture than it used to be.
I can get you a definitive answer about Ft Hood in a few months when my son gets there. He's a TACP officer, so he will probably be in your old unit. (They renamed the career field a few tears ago.)
