I remember my father talking about the first Black replacements assigned to his battery in Korea in 1952, and how his first sergeant felt it necessary to beat the crap out of them so that they would "know their place". That was two - or maybe three - generations ago. I expect that the people who will have problems with this will be a very small number of senior enlisted people (sergeants), as well as those who have trouble with anyone who isn't exactly like them. Ten years from now, we will all wonder...what was the big deal all about?
