Yeah, couldn't remember any, that's why I figured you'd need to ally it in. Bringing friends with strengths you don't have is a time honored Chaos tactic that started with the words 'Traitor Guard'
There's not even an Ally Matrix to worry about anymore in 8th, additional detachments can now deliver truly weird things.
Yeah I figured, however even looking at Traitor Guard doesn't solve the problem, as they don't have any snipers either. Nothing is present in Chaos Marines, Deathguard, Thousand Sons, Daemons, Traitorguard or FW chaos overall.
If I could find any, I would bring them in a heartbeat.
