A male Human named Koris Haslam commanded a commando unit that fought for the Rebel Alliance. Within the Rebellion's armed forces, he was well-regarded as a commando of considerable skill.
Haslam's missions included an operation to rescue Gebnerret Vibrion from the Imperial detention center on Selnesh. His team consisted of Melenna Seltrayne, Gowan Ch'lessan, Liak, Barsoulentinial Enkhet, Dr. Aurin Leith, and himself. He questioned the inclusion of Dr. Leith, who was against potentially killing Vibrion instead of letting him be interrogated, and even proposed a reprogrammed medical droid as a better alternative. Despite his concerns, Haslam's team successfully extracted Vibrion from Imperial custody, although he sustained minor injuries during a stormtrooper attack. As the team fled Selnesh, Haslam took control of the transport's defensive laser cannons.
