You're making some pretty big leaps based on two and a half minutes of a 2+ hour movie. You also have to keep in mind that this is the very first trailer.... the first ones rarely have anything of substance to them. They're usually just action-packed attention-getters. Looks interesting enough. Not a movie I would traditionally watch, but in recent years I've been finding that I've really enjoyed some of the recent the WWII "inspired by true events" movies, so I'll probably check it out for that.
