glacis (dict)

GlacisA glacis ( or ) in military engineering is an artificial slope of earth in the front of works, so constructed as to keep an assailant under the fire of the defenders to the last possible moment. On the natural ground level, troops attacking any high work would be sheltered from its fire when close up to it; the ground therefore is raised to form a glacis, which is swept by the fire of the parapet. More generally, the term is used to denote any slope, natural or artificial, which fulfils the above requirements. See also: fortification, siege. The glacis plate is the front hull armor of a tank or other armored fighting vehicle. It is usually the thickest and strongest armor on the vehicle, and often well sloped to increase the possibility of deflecting antitank fire.
