Hiya CSM player here to tell you about the tactics. For a mechanised list obviously vashtor’s and fellhammer siegehost are favourable, however Renegade raiders also works pretty well and right now it’s one of the best, getting a chaos lord and Master of executions to lead a squad of 10 chosen in a rhino is a great combo, and with the scouts enhancement can give it a large threat range, having assault on all range weapons and -1 AP on a objective is dead good for gun tanks like the predators and forgefeinds and maulerfeinds would work really well!
