Anthropologists in war zones

I was most interested in the article from the New York Times about the anthropologists that are working in the war zones with the US military. I found it rather ironic that they need to bring in specific anthropologists to do this work. Would it not work just as well to properly educate the soldiers that are going over there? If so, and they could have soldiers that are sensitive to the surroundings and cultural life of the people they are surrounded by, then maybe the soldiers wouldn't be looked at as bad as they are now. Instead, they have to send over people to help the soldiers "communicate" with the civilians?
