Ras was a member of Ion Team, serving as a clone commando within the ranks of the 22nd Air Combat Wing during the era of the Clone Wars.
During the year 19 BBY, Ras participated in the Battle of Murkhana, fighting alongside the Jedi General Roan Shryne. In collaboration with his fellow soldiers Captain Climber, Trace, and another commando, Ras played a role in disrupting Commander Salvo's attempts to execute Order 66. This action resulted in the rescue of Jedi Shryne, Bol Chatak, and her Padawan Olee Starstone from certain death. Subsequently, Ras and the remaining members of his squad were captured and brought before Darth Vader, who proceeded to kill him, and another commando.
