One more interesting tactics is usually called Attack in Oblique order. It is extremely efficient while assaulting buildings and means that your team attacks only one flank totally refusing another or you concentrate the vast part of your team to a single flank.
This strategy gives you an opportunity to use force imbalance in conditions when opposite team can’t make quick reposition of its forces from flank to flank and the vast part of the opposite team’s forces becomes useless, because it have no hand in the game. In this case if you breakthrough the flank, you can easily capture the central point.
