Volunteer firemen do. Should be more of them and less of the professionals who seem to retire terribly early, claim disability at a torrential pace, and receive amazing benefits from the engagement... while doing a lot of sleeping around the firehouse.
Definite exception..:oP
Point is I don't know why a select group "deserves" a pension for work they are already paid well for. That's how you end up with 200K a year lifeguards who retire early with lavish retirement packages and then try to defend them what challenged... I might however not argue against the military...
