In the latest paperback rulebook (page 161) a disc of Tzeentch's troop type is war beast (W.
However (page 104), a character riding a mount with 1 wound counts as riding a cavalry mount . Furthermore (page 84), if a character is riding a WB the model uses cavalry rules .
Does anybody know OFFICIALLY which troop type a disc rider is, and most importantly which units it can join or benefit by "Look out sir!"?
