Flying wedge

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.

Military tactics

Antiquity

Greeks and Romans

The wedge (έμβολον, embolon in Greek; cuneus in Latin, colloquially also caput porcinum, "boar's head"), was used by both infantry and cavalry. The men deployed in a triangular or trapezoid formation with the tip leading the way. According to Arrian and Asclepiodotus, the wedge was first used by the Scythians, and then the Thracians. Philip II of Macedon adopted it from them as the main formation of his Companion cavalry and Alexander the Great faced Persian cavalry arrayed thus, as Arrian attests. The use of this formation enabled the concentration of missiles against a limited front and thus was used not only to smash into the enemy line, but to also add to the effectiveness of long range, usually hurled weapons like javelins and hand axes.
