Mine is WW2. I have read over 1000 books on the topic and have done WW2 tours. Would like to get to Stalingrad (Volgograd) some day.
One of the great ironies of my life was that my dad served in the British Merchant navy during the war and was on Arctic Convoys and we had an ashtray at home made out of a shell which hit his ship and didn't explode but I never once spoke to him about it before he died :(
