In military tactics, a flanking maneuver, or flanking manoeuvre (also called a flank attack), is an attack on the sides of an opposing force. If a flanking maneuver succeeds, the opposing force would be surrounded from two or more directions, which significantly reduces the maneuverability of the outflanked force and its ability to defend itself. A psychological advantage may also be present, as flank forces usually do not expect to be attacked.
A larger-scaled tactical flanking is called a strategic flanking, where the targets of the flanking could be as large as divisions or even entire armies.
