Initially intended to replace the Crimson Empire's Shock Troopers as the primary enforcers of Darth Trayus's rule, it was instead decided to make the Sith Vanguard under Trayus's direct command elite individuals independent from the Crimson Empire's army, retaining their initial purpose. While technically not part of the Crimson Empire's armed forces, the Sith Vanguard often acted alongside the Corps and army, both on and away from the battlefront. Sith Vanguard soldiers quickly became feared individuals within the Crimson Empire's ranks, and had their loyalty to Trayus not been unquestionable, it would have been safe to suspect possible treason down the line.
