Two of my uncles were on the ground in the Battle of the Bulge. One of them, I learned to never ask him about it again after asking the first time. Dad was in the Pacific at Okinawa. He did not detail any battles. That stuff was really nasty and war IS hell.
My good friend just finished an OLLI class on the 77th ID which served in ww1 and ww2. His dad was 1st Sgt of a medical clearing unit so was close to the front. He served in the Pacific Leyte and Luzon before Okinawa. (Hacksaw Ridge). We spent 25 % if the class on Okinawa. Brutal. Eastern Front brutal.
