They are held as examples at plenty of US military officer training programs, thankfully. I learned about this incident and Hugh Thompson at the USNA, where they drilled into our heads that morals, ethics, and the laws of war are absolute and it's the officer corps job to ensure they are followed to the T. I always took that to heart. Unfortunately, as in the civilian world, there are crappy people in the officer corps that don't care much (the American GIs that Mr. Thompson was up against that day, for example).
