AIUO (Atsinan Intelligence and Undercover Operations) units are prepared to be sent abroad. They have all the licenses and appearance of normal citizens of Atsina. They watch for spys in Atsina, or when sent abroad, attempt to learn the location of military secrets, or locations of things that can be used by the military. They also track people who are suspected of being Spy's. You may find them loitering around Military Bases, appearing to be normal citizens. They watch for people who continue to look at the Base, possibly trying to find secrets about it, and they then question the person. If the person is a spy, they are executed.
Countries that have AIUO in them (This information is kept locked up with other very secret, government documents): NONE
