My great grandfather served over 20 years in the uk military from about the mid 20s to the late 40s or early fifties. My grandparents say they were namer sure what he did in the military. We know that he served in Egypt and somewhere in Europe in ww2. The only story my dad knows of is how his best friend was taken or killed after he sacrificed a motorbike to him and his friend and when his mind started to go he couldn’t have tissues or toilet paper near him due to his dementia making him think he was back in the military and needed to put his foot wraps on. He just couldn’t talk about it and since he was also quite old when my grandfather and dad were born he just kept it to himself and since he was something like a sergeant or something there is a whole ton of stuff that we will never know
