When I was stationed in Berlin, Germany, those things were everywhere. They were not afraid of you. A few MP sedans were crashed due to those pigs.
There is a forest outside of Berlin called the Grunewald. We would do a bit of training out there and those critters would come wandering into our tents. We wanted to shoot them, but the Germans would go crazy. The only thing that make them wander off was a chainsaw.
2 soldiers were seriousy injured when pigs fell into their foxhole that was covered by a shelter half. Beat the crap outta those guys.
Germans called them "Grunnie Pigs". I hated the things, but I woulda liked to eat one
