so at the risk of asking a stupid question i was wondering if someone could explain to me how the new alleys rule works in 6th ed? the reason i ask is i have been told that i do not suport my death wing army well so while i have been looking through my own codex for an answer to this question i am at this point wondering if it would be possible and at the same time useful/ a good idea to include a sqd of leman russ battel tanks to my army inorder to give them some rolling back up?
