Ok, a Skaven Warlord is mounted on a Bonebreaker. Bonebreaker is on 40x40mm base.
If I put him in a clan rat unit. The bonebreaker perfectly displaces 4 clan rats.
So based on this. Assuming the clan rat unit stays above 5 models.
The warlord cannot be targetted by normal shooting attacks.
and against template weapons he should get Look Out Sir.
I've been over the rule book, I just pulled up the FAQ's and did a search, but could not find anything countering the above, BUT when I look on the various forums. I see people saying "nothing in the skaven army can give a bone breaker Look Out Sir"
Where is this from? I must be blind or something, I cannot find where in either the rulebook or a FAQ where this is denied.
