Point defense gauntlets, also known as Jackal shield units, or an energy pavise are arm-held energy shields mainly used by the Kig-Yar serving in the Covenant for protection from enemy fire or close- to mid-range explosions. The point defense gauntlet was developed by the Covenant after they reverse-engineered Forerunner technology. The shields are approximately 1.22 meters (4 ft) in diameter.
