Hope someone can help me out, recently I keep hearing that the cannon on the Vanquisher is twin linked if the coaxial storm bolter hits the target first. Saw this first on a battle report online and then keep seeing it pop up. I have looked through the codex, the latest FAQ , and three Imperial Armour books, Imperial Armour Vol 1 Second Edition, and Siege of Vraks I and III, but can't find any actual rule to support this. Does anyone know where the rule is? Or is this just wishful thinking that has caught on?
