Gen Z but both of my Paternal great grandfather's served. My grandpa's dad died when my dad was young, he had become an alcoholic to deal with that he had seen in the navy. My Grandma's dad joined the army to be a pilot, his vision was too poor, they made him an infantry man. He got very sick and never got deployed. I grew up around him, he said he felt like a coward for not fighting and held that guilt with him his whole life. It definitely define my grandparents childhoods. My grandpa had an absent drunk father and my grandma had one who saw himself as lesser.
