This is my rifle, this is my gun. This one's for fighting, this one's for fun. Quote from "Full Metal Jacket."
"If you would have peace, be prepared for war."
Quote from Appius Claudius,
Rome
Actually I learned that one from my platoon Sergeant, when I was a little slow in referring to my rifle (properly) as a "weapon" not a "gun".
It's interesting how well you can learn the proper reference when chanting that ditty while running in a large circle with your weapon held over your head for an extended period of time.
Still never call "weapons" "guns", and it's been thirty years.
