These turrets, armed with a pair of lasers, are hidden in underground armoured compartments and deployed when the situation calls for it. Three of these turrets are linked to a single hub, and each turret is capable of self repair as long as the hub remains intact. They are weak against infantry but effective against vehicles. They are also unable to target aircraft. Even though the three turrets can be destroyed, but as long as the hub is intact, they slowly rebuild before redeploying.
