Sweeping advance and WBB

Sweeping Advance removes the unit, and no special rule can save them. Period. WBB does not have a statement (such as that in ATSKNF) saying that it disregards Sweeping Advance. SO no, WBB does not work against Sweeping Advance, and yes, all the models in the unit, to include damaged (downed) models are removed. Sorry, but that's just the way it works since 4th ed and that's the way it works in 5th ed.
