- "May I present our first Elite Squad. Top soldiers from across the galaxy."
An Elite Squad of the Galactic Empire's armed forces was led by Clone Commander CT-9904, and was composed of new recruits assembled by Vice Admiral Rampart. The squad consisted of Elite Squad Troopers ES-01, ES-02, ES-03, and ES-04.
In the wake of Clone Force 99's refusal to kill Saw Gerrera's rebels and subsequent defection from Imperial service, the newly-anointed Governor Wilhuff Tarkin deployed CT-9904's Elite Squad to finish the mission, determined to see if Rampart's enlisted soldiers could succeed where the fugitive clones failed. The troopers successfully ambushed Gerrera's camp on Onderon, killing several insurgents.
However, Gerrera had already left the camp by the time of the squad's arrival. CT-9904 ordered the troopers to execute the prisoners, but ES-01 refused to comply with a command to kill unarmed civilians, and was consequently killed by the commander. The squad's remaining members obeyed CT-9904, executing the prisoners while the clone watched. Despite the loss of ES-01 and the failure to locate Gerrera, Tarkin and Rampart considered the mission a successful field test.
