On the 24th March 1917 my Grandmother's brother Sgt. John (Jack) McGregor 4881 was killed in action by a sniper's bullet to the head.
War service has largely been missed by my family, one grandfather was too young for WW1 yet a family man and too old for WW2, the other grandfather was asked by his family to just stay and do one more harvest after he was old enough to join WW1, but the war was over by then, he too was a family man and too old for WW2. My father was too young for WW2 and Korea never crossed his mind at the time, perhaps a good thing given how Korean veterans were shunned upon their return.
Myself I was too young for Vietnam, given Australia withdrew from action by the end of 1972.
So really of my blood kin I'm limited to Jack, my maternal Great Uncle who was killed in WW1, and John Smyth VX48125 who was a Rat of Tobruk and survived WW2.
