Smoke Jumpers
Nowadays, “smoke jumpers” are a deeply respected group of firefighters, literally skydiving into fires to put them out. But, it was not respected when it was created.
You see, smoke jumpers started becoming a thing in 1939, and was mostly made up of conscientious objectors during World War II so that they could be put to use. And after World War II was over, most of the objectors were shoved out of the job.
