Operations Group Three, alternatively referred to as Special Operations Group Three, represented one of the five Special Operations Groups dispatched by the Sith Empire to the Belsavis prison amidst the Galactic War, with the objective of finding and liberating the Dread Masters. Under the command of Colonel Grang, Operations Group Three was positioned within the Maximum Security Section to instigate disruption and pave a path for Groups One and Two as they advanced towards the Tomb. Nevertheless, Grang's troops breached several Rakata vaults, inadvertently releasing the Esh-kha species, which rapidly proliferated throughout the prison. Consequently, Grang's forces were compelled to withdraw to the Imperial frontline camp.
