Update (Alpha Legion Land Raider)

Weaken Resolve with Divine Pronouncement on non-fearless units

I have a chat with a going to be guard player yesterday. While he listen to how Ahriman can turn a Ctan deceiver into a spawn, he told me that he will use a 9 men primaris pysker to counter the Ahriman or any psychic attack (something to reduce the sorcerer's leadership to 2) I really don't know anything about guard's rules... but need you guys to help me out here... does that particular psychic attack affects units embark in a transport?
