This pretty much on the mark. I'd only add that even though the military is uber hierarchical, in good unit's it can be seem fairly flat. Everyone does PT together every day and when I was in the CO would be doing pushups and running with a section every morning. It's a closer team and less bureaucratic leadership so standards are kept in check by the collective. Even though there were pay and rank differences, everyone was in it together where in the police it seems very much like you're on your own.
