My dad landed at Iwo Jima, Green Beach on D-Day. 5th Marine Division; Pioneer. Stayed until the end. He left us in 1999.
I sure miss him.
Once when I was visiting him, the movie Sands of Iwo Jima came on and we watched it together. He thought it was a realistic depiction of combat (of course he had not been on Iwo Jima himself).
