We are a Navy family and my son was the commanding officer of a DDG. I had 17 years as a liaison officer with the Naval Academy. I thought the movie did a great job of capturing the operational life aboard. The tempo, the constant challenges, the pressure, etc. My only minor criticism was that I thought the sailors we a couple of years older than I would have expected. My family members who fought in WWII were just 18 when they deployed.
