One of my grandfathers was in the Great War. With the Royal West Kents, I believe. There's a photograph of him in his uniform sitting with my grandmother on a cliff-top overlooking the sea. I know nothing of what he did or went through. He died before I was born- stupidly young- of a botched operation on his sinuses.
My other grandfather was training with the RAF when the war ended.
My father was with a Royal Naval bomb disposal unit in WWII. Now that was brave.
My mother was a driver on the home front.
My Uncle Dick, a captain with the Royal West Kents, was killed in 1943, on the Adriatic coast- and is buried at the Sangro River war cemetery.
