In Tiberian Dawn, the turret is Nod's ground defense structure although it is biased toward the anti-vehicle role. It may operate without power. In Renegade, two turrets and an Obelisk of Light defend Nod bases in C&C mode. The singleplayer mode also features a gigantic version, called a Shore Defense Cannon, which is guarded by SAM sites. Nod switched to the more general purpose laser turret by the Second Tiberium War.
