In fortifications, a form of angled breastworks shaped like a V with its point facing the approach of the enemy
A fortification with two parapets or low walls whose faces unite to form a salient angle towards the enemy. That is, they form a point that juts out past the rest of the defensive line of works.
(Fr.) - a detached fortification with two faces forming a salient angle, often built as an outer work to cover an advanced position. The work was open at the rear. A redan was a common form of all military eras. When bisected by a traverse down its center (along the capital line), it was called a flêche, or "arrow." When connected to adjacent strong points by curtain walls, it served as a caponière.
Redan (a French word for "projection", "salient") is a term related to fortifications. It is a work in a V-shaped salient angle toward an expected attack. It can be made from earthworks or other material.
