My dad was 4-F--almost legally blind--but was a war correspondent. First wave, Omaha Beach, D-Day, through the breakout.
Four of my mother's brothers served in the Army. One went to the Aleutians. Never talked about it, but later took his own life. The other three fought in Europe. At least one, and as I recall, two, were in on the liberation of concentration camps in Germany.
My dad's brothers were too old to serve, I think. Dad was the youngest of nine kids and I never knew most of his family. Long, sad story.
