Which book is the prot raider available to chaos? Cos it ain't in the 2013 imperial armour apocalypse, only loyalist, plus it isn't an assault vehicle. But that's pretty sweet for cheep las cannon raider, personally the Spartan takes the biscuit for an extra 50 points over standard raider you get an extra 2 las shots and capacity for another 15 mods.

Try mark of Khorne on the cultist's if any.
I don't have the vracks books,but if it is available in any of those lists then you could have it in a secondary detachment.
