The automated turret is built onto a Keep or Covenant citadel, and defends it from any attackers. It is slightly expensive, but effective against infantry, vehicles, aircraft and leader units, but requires a military presence to help defend it, maybe five or six squads, or it will be overrun and destroyed.
This unit can be upgraded to become either an Anti-Infantry Turret, which uses a Plasma Mortar, an Anti-Vehicle Turret which uses a large Fuel Rod Cannon, or an Anti-Air Turret, which uses a Heavy Needler. Each of these upgrades cost 100 resources, and the actual turret can be upgraded to medium or large turrets at the temple.
- When fully upgraded, the Heavy Turret has a slight resemblance to an Elite's skull.
