The ultimate supercommandos - the ARC (Advanced Recon Commando) troopers are clones who were personally trained by Jango Fett. Only a select number of ARC troopers were bred and trained before Jango's untimely demise at the Battle of Geonosis. Activated shortly after the start of the Clone Wars - ARC troopers are used for only the most dangerous missions in which a substantial amount of independent thought and iniative is required.
They are equipped with highly advanced clone trooper armor and formidable heavy weaponry. Whether they are fighting on their own or at the side of the Jedi - the ARC troopers are a symbol of the Republic's military superiority over the droid armies of the Confederacy.
