The Communications Officer, or Com Officer is a supplementary astronaut rank aboard the Habitat. The Com Officer is in charge of the maintenance and use of communications systems on the Habitat, both alpha and beta, whether they be CAPCOM, AUXCOM, telephone, cameras or other technologies. Generally, the Com Officer will be given CAPCOM or AUXCOM shifts more than any other astronaut. The Com Officer should have an understanding of how the systems work in the beta reality, such as the IEST. Of course, the Com Officer is subordinate to the Habitat Commander. The Com Officer is a specialized astronaut position that does not necessarily need to be given, as the maintenance of communications systems can be done by the Engineer.
