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. 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

. It is generally believed that the Germanic tribes were more successful with this tactic than the Celts. It was used to force the Roman forces to split and was later applied specifically to the weakest units. Due to the high discipline this formation required and the relatively high probability of failure, it is assumed that the front lines were filled with the best and most heavily armoured warriors of the Germanic sibbs who had to break the Roman front line. Here the individual warrior tried to gain fame and glory in the battle. The most distinguished princes and their acolytes stood at the head of the ''Keil''. However, this was also the most dangerous point, whence the need to be heavily armoured. But an army leader who survived a lost battle often forfeited his life (usually suicide). Warriors who had fled were hanged or slain. According to the Roman historian

with forty warriors in the first line and 1,600 men strong. In this formation, the wingmen are at most risk. It was therefore well possible that the wing marched with some caution and held back a bit, so that the center stormed further and looked like a wedge. The outer ranks of the rear on the other hand swelled slightly. The goal was to hit hard at the same time and to drive a 40 yard wide hole into the enemy line, according to the German historian Hans Delbrück. According to

s to the sides. The triangular formation was used to overwhelm an enemy with a frontal assault. Family groups and tribes were placed side-by-side in units to maintain its cohesion in battle. The tactic was a formidable assault strategy against defenders in line or column, however, attackers faced annihilation in the event of retreat because the wedge became an ill-defined mob if its forward momentum collapsed."Quodque præcipuum fortitudinis incitamentum est, non casus, nec fortuita conglobatio turmam aut cuneum facit, sed familiæ et propinquitates" - ''Tacit.

formations when defenders would link their shields together to form an all-but impenetrable barrier. Armored, heavily armed infantry could use their momentum in wedge formation to drive open small sections in the shield wall. This would break up the shield wall exposing the defenders to flank attacks.

, then a final rank of 14 picked men to hold the formation together. Sir Charles Oman refers to an unpublished manual of 1480 by Philip of Seldeneck which describes the formation, calling it the ''Spitz''. He gives examples of various formations varying from 200 men to 1000. The formation of 1000 men places seven men in the first rank, with each rank increasing by two men back to the eighth rank with 21. The remaining men are in a column 20 men wide behind the point. The banner would be carried in the seventh rank. The use of the cavalry wedge in 13th Century Castile is described in the

s in the third chapter of his '' Praecepta Militaria''. There, he relates that the wedge must be formed by 354 cataphracts and 150 horse archers to a total number of 504 men. The row of the first line comprised 20 horsemen, the second 24, the third 28, down to the 12th line, which consisted of 64 men. If such a number of men is not available, he proposes that the wedge be formed by 304 cataphracts and 80 horse archers, or a total of 384 men, the first line comprising 10 men. In his next chapter (''Ordinance on Cavalry Deployment''), he ordains that the wedge must be accompanied by two cavalry units, which will guard its flanks. A wedge whose ranks are not complete in the middle is shaped as an Λ instead of a Δ and is called a hollow wedge, or in Greek κοιλέμβολον, ''koilembolon''.
