The resistance forces opposing the Imperial takeover of Corellia have been surprisingly successful, especially given their irregular and disorganized nature. These mostly civilian guerilla fighters are composed of freighter crews, unemployed mercenaries and patriotic citizens of all species who are all willing to fight for Corellian freedom. CorSec, the Corellian police force, has played a particularly vital role in coordinating and training the rebels.
During the invasion's first days, Corellian rebels successfully assassinated over a dozen high-ranking Imperial officers and bombed shipyards used as landing pads for the Empire's fleet. Leaders of the invasion force quickly learned to think twice before allowing “cooperative” Corellians access to Imperial bases.
