Military Police: Town Patrol (1955)
https://www.youtube.com/watch?v=w_-UbRxlxCk
The 28-minute short shows two MPs as they patrol Agusta, Georgia. And it looks like someone spliced scenes from an entertaining-enough police procedural to make a dull educational film.
The MPs instruct one soldier on bus routes and pay close attention to try and spot soldier's shoes. But in between all that they come across a soldier who was beaten up and mugged.
In fact, the line "You better call the station and get an ambulance" is spoken with much less severity and gravity than the following dressing down of a poorly dressed soldier. "Okay, now you look like a soldier, you weren't doing yourself or the army any favors looking like that".
In fact, the film spends roughly the same amount of time around buses and bus stops as it does showing the MP's tracking down a soldier who's gone AWOL, attacked a blind man, and has started robbing art supply stores.
