There's no way around it: battle sequences are tough to film.
First, just capturing the mere scale of the battles is a challenge in and of itself, but then you have to get all the technical aspects and military minutiae down. And that's just the tip of the iceberg. When all the hours of footage are shot, filmmakers still have to go to the cutting room and turn them into the adrenaline-pumping scenes that we all love.
Making a military movie is no easy task -- and even with all of the attention to detail, research, and expert storytelling that goes into them, they're not without their faults. And, as evidenced in the photos below, some of them are glaring.
