I don't know if I should upvote you because they actually act like this or downvote because you reminded me of having to deal with it, even as a civilian.

My grandfather was in a WWI German prison camp as a child (his father was British and all British subjects in the UK were put in prison camps when the war broke out). It was largely autonomous, and when POWs started arriving, the enlisted acted as indentured servants to the officers.

Yes, WWI not WWII. I'm old.
