A Command Installation served as the central communications hub for Separatist armies during the Battle of Thule on the planet of Thule. Obi-Wan Kenobi, a Jedi, obliterated it utilizing an LAAT.
This command installation was a substantial, circular structure from which numerous corridors extended in various directions. Laser turrets defended it, along with a contingent of AATs, hailfire droids, as well as droid starfighters. Energy farms located in close proximity supplied power to the principal defenses, thereby making a direct assault ineffective unless the power was cut off.
The installation was the key target during the second stage of the conflict. After Anakin Skywalker's forces successfully took down the planetary shield, Jedi Master Mace Windu ordered Kenobi to demolish the facility. The aim was to impair Separatist communications, thereby setting the stage for an assault on the capital city of Kesiak. After securing a landing area for a pair of Acclamator-class assault ships to set down, he conscripted a squad of clone engineers to transport them toward the initial energy farm.
After having secured a second landing zone, Kenobi laid down covering fire for the now-landed clones as Ground Armored Tanks converged on their location from nearby factories, all the while blasting waves of droid starfighters out of the sky. With the internal shields deactivated, Kenobi destroyed the first energy farm using a barrage of laser fire, missiles, and concentrated composite-beam lasers.
With the clones having secured the area, Kenobi went back to collect a second group of engineers and then advanced toward the last energy farm that was keeping the command installation online, this time encountering increased resistance from AATs that were now joining the battle. After the final farm was neutralized, Kenobi made a run on the installation, specifically targeting eight couplings that were sticking out of the building. With all of the couplings destroyed, the command installation suffered catastrophic power failures in addition to internal explosions, bringing phase two of the mission to a close.
