An armored brigade belonging to the Grand Army of the Republic fought alongside the 501st Legion throughout the Clone Wars. This brigade was composed of a minimum of twenty-nine All Terrain Tactical Enforcers and saw action in the Battle of Bothawui; there, they were positioned on the Fervse'dra asteroid belt and executed a flanking maneuver against the Separatist Alliance fleet commanded by General Grievous. As Grievous and his fleet proceeded through the asteroid field toward Anakin Skywalker and his forces, maximizing the power of their forward deflector shields to accomplish this, the tanks were able to successfully engage the Separatist ships from their rear.
