Most are happier having left their guns behind in the past.
One of my former employers became a peace activist following highly decorated service in Vietnam. He shot and killed a lot of people including the teenage kid who shot him and permanently ended all his dreams of becoming a professional athlete. Minus one fully functional leg.
My dad and my father-in-law both served in the military but have never been fond of guns. My dad was a nearsighted
Radar O'Reilly clerk assigned to a medical unit that didn't end up in Korea. My father-in-law was a Navy medic assigned to the Marines and used as a guinea pig assigned to atomic bomb testing.
My father-in-law was on a ship to Korea in 1953 when the armistice was signed. From there he was diverted to military units still studying atomic bomb damage in Japan. He's one of the few people I know who has witnessed a nuclear explosion up close, at the most minimal distances of survivability, and hopefully among the last.
I did a dance with the Navy. Even after they got past my asthma and crazy, they still offered me a civilian teaching job, which I declined. Which is ultimately how I met my badass wife these 30+ years.
Sometimes a guy like me gets lucky.
