Battle of Colla IV (Clone Wars)

Late in the Clone Wars, a battle took place on the Colicoid spawnworld of Colla IV when the Galactic Republic launched a strike on the Colicoid Creation Nest, a corporation that manufactured battle droids for the Confederacy of Independent Systems. While Republic assault ships shelled the planet's surface, four platoons of clone troopers infiltrated the Colicoids' shielded factory. There, they were attacked by a Scorpenek annihilator droid that took out three platoons within minutes. After the surviving members had fled from Colla IV, ARC trooper Sergeant Stec reported on the failed mission to his superiors and brought back information on the first-ever encounter with the annihilator droid. Meanwhile, expecting the return of the Republic forces, the Colicoids brought the droids to the front lines to support the Separatists' war effort.
