Rebel Rock was the codename given to a sniper in the resistance movement on Cilpar in 4 ABY.
During the battle to liberate the planet from Imperial occupation, Elscol Loro and Wedge Antilles were being pursued in their landspeeder by a pair of TIE fighters. As the enemy fighters came dangerously close to hitting them with their laser cannons, Elscol wove the landspeeder between a rock formation, and as they passed through the far side one fighter was destroyed by a shot from a high-powered rifle.
