[Source] A Dug rail gun was a Dug artillery piece that served in Malastare's armed forces during the Clone Wars. They were used at the Battle of Malastare, where they bombarded the Separatist Droid Army, notably as anti-air cover for BTL-B Y-wing starfighters against Vulture droids as they moved to the drop point for the Electro-proton bomb, which neutralized the opposing force. In the aftermath, the rail guns were again used in an attempt to kill the Zillo Beast which was awakened by the detonation of the bomb during the battle. Unfortunately, every single rail gun was destroyed.
