Thanks for posting this.
The Army News ran a story for the 75th year observance, 3 years ago in 2016.
Former OGR Forum poster, David Vergun, wrote a nice piece from the Army's perspective and used a couple of my father's photos (you can read the captions if you click on "show caption"). He was stationed there soon after the attack to both help in protecting the area (no one knew if there would be additional attacks) and for training.
