I must say, Che never looked better, than in that picture.
I was still a few years from the Army when I was reading about his death, but I already had a lot of respect for our GIs fighting in Vietnam and our Green Berets working all over in different countries, and especially Latin America, which I already had an impression of, as their primary work area outside of Vietnam itself.
All I needed was a few clues and I had a pretty good idea of our level of American participation.
