(coexisting on another dimensional plane)
The Terran raider was a type of small craft used by the Terran Rebellion, in the mirror universe, against the Klingon-Cardassian Alliance. The ships were equipped with warp drive and armed with at least one phaser.
Most of the rebellion's raiders were destroyed during the battle to capture Terok Nor, but Julian Bashir and Jadzia 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 ISS Defiant. Bashir's raider returned to join the Battle of Terok Nor, and helped cause serious damage to the Regent's flagship. (DS9: "Shattered Mirror")
