Another public service sector job that can be hazardous but rewarding is a law enforcement career. Most police officers earn at least $45,000, depending on where they work. Detectives can earn considerably more than that. There are many positions in the law enforcement field that may not necessarily be dangerous but may afford a decent retirement as well. It takes a lot of personnel to run law enforcement agencies and a desk job could just as easily yield a nice retirement pension. Meanwhile you get to retire from most law enforcement jobs after just 20 years. Then you will enjoy pension benefits that are usually about 50% of what you earned on the job.
