Title: Understanding Girls und Panzer in 3 Minutes!! This is basically a short, 3-4 minute video reminding you what Girls und Panzer is all about. It was shown in the theatres before the main movie 'Girls und Panzer der Film.' It's an okay watch and probably not a bad idea before watching 'Girls und Panzer der Film' in the comfort of your own home. That said, I think the recap video, 'Girls und Panzer Compilation: The 63rd National High School Sensha-do Games,' which is two hours, does a better job of making you remember essential scenes from the events before the movie. I recommend watching that before watchingder Film.
