Battle of Colla IV (Clone Wars)

The Battle of Colla IV was a battle late in the Clone Wars, when the Galactic Republic launched an invasion of Colla IV, homeworld of the Colicoids who provided the CIS with droidekas and tri-fighters. During the battle, four platoons of clone troopers advancing on a shielded factory were attacked by a single Scorpenek annihilator droid, which destoryed their only cover, killing three of the platoons. One known survivor of the engagement was Stec, an ARC trooper.
