I've contacted someone at the school to verify that they use the text and will try to find out in what context it is being used (don't count on a response as to the latter as I'm not sure if that would be considered classified).
Please keep in mind that this is a "Special Forces" school and that very few people in the military actually attend them. I can tell you that the book is not here at my office even though we might be using something like it if the Gov't really thought it was useful in identifying the "enemy".
I hope I haven't given the impression that I'm right wing or militaristic. I just know that the folks that I have worked for and with (with few exceptions) and known throughout my life are decent people that would not be accepting of anything that is this blatantly racist. The idea that we all go around calling them by racist names is ludicrous. Just like thinking that the liberals among us are commie, pinko, etc. etc.
