The photo of them eating their rations in the grass reminded of a boss I had. He did a couple tours in Vietnam as a field medic.
We were talking about some nice parks and campgrounds in our area. I asked him: “hey Jack, that sounds like a nice place - have any interest in being out in the woods and camping?”
His deadpan reply was: I spent two years “camping” in Vietnam. I have no interest to go camping again.
I was never in combat but I was in the Marine Infantry. When someone mentions going to the beach I say “I’ve seen a beach before”. No interest in going to the beach.
