Between 39 BBY and 36 BBY, the Trade Federation sought control of the moon Alaris Prime. They faced attacks from the gundark creatures in their early landings, causing the company to send a squad of eleven Battle Droid Beta Versions to attack the gundark nest. As the attack began, Wookiee bowcaster troopers led by Chewbacca, who were the rightful colonists of Alaris Prime, arrived at the nest with the same goal of eradicating the gundarks. The battle droids finished their task and immediately turned on the Wookiees, perceiving no difference between them and the gundarks, but Chewbacca's Wookiees quickly dispatched the droids.
Battle Droid Beta Versions ambushed Attichitcuk.
The leader of the colonists, Attichitcuk, encountered seven Battle Droid Beta Versions on a scouting mission. The droids ordered the Wookiee to halt and shot him with their blaster rifles when he refused, seriously wounding him. Chewbacca mounted a rescue of Attichitcuk, first encountering three Battle Droid Beta Versions near the ford of a river. They destroyed another four on the other side and a further six on their return trip to their base.
As the Wookiees became more aggressive in their attacks on the Trade Federation, the Droid Army commander LUH-989 sent six Battle Droid Beta Versions, along with three beetle droid, to attack a camp belonging to Chewbacca, who had become leader of the colonists. Chewbacca's ally Shoran warned his advisor Qui-Gon Jinn of the attack, who told Chewbacca to prepare his defences. The beetle droids reached the camp first but were destroyed by Chewbacca's soldiers, and afterwards the Battle Droid Beta Versions made it to the camp and met the same fate.
