My grandpa (mom's side) (he's still alive btw, if that matters) was in the army during 1973 pinochet's dictatorship. According to him, he was a suboficial mayor or alferez rank during his time there; he told me he had to scold Pinochet various times during his time in Santiago. My grandpa was born in valdivia if you ask. He never wanted to be in the army, but rather in the air forces because that was his dream, to be a pilot; he never managed to get listed into the air forces because he lacked the funds to do so. My grandpa comes from a family of farmers, so you get the idea. (snca trivia: My booru and wiki username is from a jet fighter called "Northrop F-5" which is my grandpa's favorite jet).
My great-grandfather (dad's side) was in the navy, just like my grandpa from my mom's side; he was also serving during 1973 Pinochet's dictatorship, though he never met my grandpa personally. I don't know much about him, though. I wish I could have asked him during his time there, but he passed away months ago, sadly.
Most of my family members (just males, though) are serving or have served in the army, navy, or air forces, so they are into politics a lot.
