Looks like they took Ramadi, driving out a determined ISIS defense force. That takes some doing, a built up area is just one solid mass of firing points and good cover. When the defenders stick to their guns, advancing into a built up area is very tough. So the Iraqi's did it, which says their Army is in better shape than this spring when ISIS drove them out of Ramadi.
The Iraqi's are giving some of the credit to effective close air support from USAF. Certainly a few 750 pound smart bombs in the right places can make a lotta difference.
