At least in the military, it's commonplace for the entranceway to the offices/working spaces of any unit to have a board with the official photos of the entire chop chain, from the President on down to the unit commanding officer.
And in basic training or the initial parts of officer training, one of the things people can be inspected on is having the names of everyone on that chain memorized. Not because that's something most military people routinely do, just to drive the point home of lawful orders and civilian control.
