Most military personal have little or nothing to do with combat or saving lives. They make an indirect contribution by doing their support jobs. The military defends our liberty more than our lives.

Cops essentially never saves lives. They either prevent crime just by being there and doing their job, or investigate the crime after the fact.

Firefighters save lives, and most are VERY well compensated at least in my neck of the woods. They get a lot of time off too...

On any given day, an airline pilot's job performance saves more lives than any other profession. Reference CA 5191. No other profession can account for that much carnage, unless a strike-fighter pilot accidentally bombs a mosque on Friday night (that would actually be considered collateral damage, ie the cost of doing business).
