C6-series battle droid

The C6-series battle droid was an advanced model of battle droid manufactured by Baktoid Combat Automata and Freedom's Grace Machineworks. The design was mass-produced by the Union of Independent Republics - the Confederacy's chief ally in the Alpha quadrant - to bolster their infantry forces in preparation for a planned invasion of Mirial. Several months before the Fleet Week Ambush, the UNSC Marine Raiders infiltrated a UIR droid factory on Hecate II, recovering a significant amount of intelligence on the droids' technical specifications and combat capabilities.
C6s were capable of wielding most conventional infantry weapons. Most of those in service during the One Year War were armed with VK-78 assault rifles, VKG-12 shotguns, or VKU-81 light machine guns.
