Fury (2014) and modern characterization in a period piece.

I liked Fury, but something just didn't quite fit about it as a WWII movie and I couldn't put my finger on it. At first, I thought it might be the modern score. Then I realized the way the characters act and talk is very...2014. When the track breaks on the tank, the engineer says, "It's broke as fuck!" The dialogue of the film took me out of the WWII period piece aspect of the movie. The characters and dialogue felt like the crew was a bunch of modern men who were teleported back to WWII. Does anyone else feel this way about the movie?
