In the mirror universe, the Terran raider was a type of small craft used by the Terran Rebellion against the Klingon-Cardassian Alliance. Most of the rebellion's raiders were destroyed during the battle to capture Terok Nor, but Julian Bashir and Jadzia Dax took one of the remaining ships and managed to delay an incoming Alliance fleet long enough to allow the other rebels to complete construction of a new warship, the Defiant. Bashir's raider returned to join the Battle of Terok Nor, and helped cause serious damage to the Regent's flagship.
The Terran raider appeared visually identical to the Federation-built Peregrine-class courier. It was armed with at least one phaser. (DS9: "Shattered Mirror")
