A flying wedge (also called flying V or wedge formation, or simply wedge) is a configuration created from a body moving forward in a triangular formation. Its primary variant is the svinfylking. This V-shaped arrangement began as a successful military strategy in ancient times when infantry units would move forward in wedge formations to smash through an enemy's lines. This principle was later used by Medieval European armies, as well as modern armed forces, which have adapted the V-shaped wedge for armored assault.
In modern times the effectiveness of flying wedge means it is still employed by civilian police services for riot control. It has also been used in some sports, although the use of wedges is banned due to the danger it poses to defenders.
