The Crisis Response Unit was a military unit of the Galactic Republic that operated in the years of the Cold War. These elite soldiers of the Republic Military were stationed on the prison world of Belsavis where they were charged with combating any uprising from the prisoners. In that time, they were under the command of Ellis Ruger who was responsible for keeping the prisoners in line. During the Galactic War, Imperial forces freed prisoners from Republic Prison Block South, fighting through the Crisis Response Unit.
