During the time of the Clone Wars, the Galactic Republic operated a strategic base located on Iceberg Three, which was a comet found within the Calamari system. Approximately in the year 21 BBY, this location transformed into a fierce battlefield as a result of an assault by Confederate forces, commanded by General Grievous, against a Republic task force led by Jedi General Plo Koon. Spanner and Joker, who were clone troopers, also participated in the conflict.
