One of my cousins was an Arty Btry commander, and he saw some of his own men attacked at a nearby village.
Perhaps Calley was guilty of "lining up women and children" as you mention in the FR mail; but how many US military were attacked as they offered food to women and children. Maybe Calley erred on the side of caution, but I'm not quite sure why you brought him into this debate.
Don't need to read too much, since I saw enough to last me a lifetime.
I am sure you would never fail to report such things up the chain of command.
