I realize that in certain situations people need a leader than forcefully yells and gesticulates and physically imposes himself or herself into a situation. Probably this is most often true in situations where those being led are not performing up to their potential or things are not going their way and they need helping focusing and remaining motivated.
However, in this situation these firefighters were professionals and doing their jobs as they were trained and everything was going according to plan. Even when something went wrong somebody as a result of their training and vigilance anticipated it and sounded the alarm within a minute of disaster and narrowly avoided a tragedy for that fire department and community.
I really enjoy listening to this guy calmly trust his people to do their jobs while not micromanaging the situation and upstaging those fire officers below him. He simply sits back and does his job which is to let his people do their jobs while he essentially functions as the dignified maestro of this professional ensemble of firefighters.
