Kaal held a position within the Sword Squadron of the 77th Air Wing. In the Battle of Kelrodo-Ai, which took place as part of the Western Reaches Operation during the Reconquest of the Rim, Kaal acted as the commander for Scimitar Flight. During the first effort to get into the shaft that descended to the hypermatter annihilator, he and the other members of Scimitar Flight were killed by a group of creatures.
