A division operated as part of the Imperial Army belonging to the Galactic Empire after the Proclamation of the New Order at the start of the Imperial Era. This division was commanded by the Imperial officer Colonel Barokki, who, in the opinion of Emperor Palpatine, was not performing well. Palpatine summoned Barokki, who gave his report in the presence of his enforcer, the Dark Lord of the Sith Darth Vader; however, Vader Force choked him due to his unit's poor results. Palpatine told Vader to release him eventually, and then thanked Barokki for the report, stating his hope for improvement in the division's performance in the coming weeks.
Darth Vader was later targeted in unsuccessful assassination attempts, which embroiled Colonel Barokki. After meditated, Vader recalled Barokki's meeting with Palpatine, and subsequently discussed the conspiracy within the Imperial Officer Corps with the Emperor. Palpatine and Vader assembled members of the officer corps, and Vader randomly chose five officers, Barokki among them, and killed them as a cautionary measure to the Imperial Military.
