Mustang in Iraq: Pity the Pakis: "TCNs. Third Country Nationals. First country is, or at least should be, Iraq. Second country is either the United States of America, Brittan, or another member of the coalition that is also a member of the economic first world. Third Country has a double meaning within the acronym TCN. Not only are these people from a 3rd country in this conflict, they are from the third world. Point or purpose? They are also treated third rate."
