Commandant, interesting! Great post! Thanks! Years ago, someone sent me a ziplock with assorted goodies from Iwo, if I remember correctly (it's not available now). Each one of the items had a history, and, naturally, I wished each could tell its story. And, but of course, that ziplock is properly stored now.
A few years ago, my wife and I were having dogs at Costco, and a fellow sitting near us was showing his buddy a small pill bottle with sand........from Iwo. He was lamenting no one today was even aware of that battle. He was in the 4th Marines, and you gotta know, I went over and asked if we could join them. He had a story to tell.
