About twenty years ago, back when I was 18, I had a cousin who worked in the oilfields of West Texas. One day while working, defined herein as doing his dangerous job to earn a buck, a massive fire broke out and Mitchell got his ticket punched almost instantly. Was it a tragedy? You bet your ass it was. Was he a hero? Of course not. Had his job involved protecting the public from fires or criminals (or orbiting the planet in a high-tech tin can, for that matter) would that have made him a hero? Again, nope. What if Mitch had seen a clear escape route but still lingered in the blaze to pull two other men to safety...hero? Yes! Heroism is defined as a selfless act, so by definition a man who is doing his job, however dangerous, is not a hero...just a brave man.
