The Obelisk of Light is an advanced Nod base defense structure used during the First and Second Tiberium War. It is an example of military applications of LASER technology.
The Obelisk of Light has been used by Nod for decades. The Obelisk is designed to eliminate any form of ground opposition with great ease using an extremely powerful laser beam. Due to the large quantities of power already required to keep a single Obelisk of Light online, anti-air capabilities were not included in the final product.
