Yep, looks like the guys at Check Point Charlie, and Alpha, and Bravo.
I was stationed in Berling 1989-90 and 1992-94.
The entrenching tool is West German, 50-70s issue before they went with a copy of our tri-fold shovel.
Differences in the boots: Officer boots are better quality and higher like a riding boot. Enlisted boots are shorter, about mid-to-top of calf, and lesseer quality, unlined.
You need a green nylon helmet net, by the way.
