Covenant automated plasma turret
The automated plasma turret is a Covenant weapon emplacement that is often used to defend prefabricated bases and other strutures. There are at least two models of the turret, the larger of which has three further variations.
 Heavy model
This model features a large, semi-circular base, in the middle of which is an anti-gravity platform like that of the Shade series. The turret, which is built around a Class-2 directed energy cannon, rests on the field emitted by this platform. Three variations of this turret exist, each of which is successively larger and more durable and has more powerful weaponry. In addition to the standard plasma cannon, each iteration of the turret can be outfitted with a fuel rod cannon for increased effectiveness against ground vehicles, a plasma mortar for combating infantry, or a heavy needle cannon for engaging aircraft.
 Light model
This model is considerably lighter than the former, being stabilized by a large tripod; as with the former model, the turret rest on an anti-gravity field emitted from the base. This turret relies on motion tracking devices to function and track targets. Despite its smaller frame, this turret is equipped with a heavy plasma cannon; this weapon is powerful enough to penetrate a UNSC bubble shield.[note 1]
- ^ Though the ability of the turret's plasma cannon is likely due to gameplay mechanics, the article assumes that this ability is indicative of the weapon's power.
