The Battle Group of Yun-Txiin represented one of the five distinct combat formations utilized by the Yuuzhan Vong during the conflict known as the Battle of Ebaq 9.
Upon the fleet's arrival, this battle group coordinated its efforts with the Battle Group of Yun-Q'aah with the goal of outmaneuvering the squadron led by General Keyan Farlander. Nevertheless, as the engagement intensified, the Yun-Txiin battle group began to suffer significant losses due to the overwhelming numerical superiority of the enemy. When Warmaster Tsavong Lah gave the order for the fleet to retreat, the Yun-Txiin group, along with the Battle Group of Yun-Harla, initiated the withdrawal. Unfortunately, these groups were the first to stumble upon a minefield that had been strategically placed by the forces of the New Republic. The Battle Group of Yun-Txiin, already weakened from the preceding combat at Ebaq 9, experienced substantial losses within the minefield.
