Paccian commandos comprised a commando squad commanded by Bureaucrat Uingali foar Marocsaa. Their activities occurred in 18 BBY amidst the Sunrise incident. This unit infiltrated the Hammer, eliminating all Kiljis and vassals present, including Tildnis. Subsequently, they seized control of the Kilji war cruiser and successfully extracted data from the vessel.
The initial, though implicit, reference to the Paccian commandos appeared in the 2021 novel titled Thrawn Ascendancy: Lesser Evil. This book serves as the concluding installment of the Star Wars: The Ascendancy Trilogy, authored by Timothy Zahn.
