All hail the Deimos Vindicator Destroyer.....
This is one sexy looking Vindicator that all Marine Chapters can take, including Chaos Marines.

This could well be the vehicle that helps Chaos Space Marines to deal with Imperial Knights. With three Strength 9 AP1 twin linked Ordnance shots at 48" range it is more than capable of inflicting some damage!

At this rate my Castigators are going to look more like Iron Warriors rather than the Chosen of Slaanesh....that said, we are descended from the Imperial Fists so all's good ;-)
Until next time....may Our Lady grant you her number.
