Missile silo
From Command and Conquer Wiki
During the Great World War II, the Soviets commissioned the Dark Horseman project to create nuclear weapons. To house these weapons, they made missile silos. In an attempt to hide these silos from prying eyes, the Soviets painted all silos a dark green to blend into the grass and foliage. Following the war, all silos were decommissioned.
The missile silo was not forgotten. Since Nod used Nuclear weaponry, it needed a place to house "the goods". Nod then designed its Temple of Nod to have a missile silo be part of the structure.
During the Second Tiberium War. It was a structure that was mostly underground with only the bay doors above the surface. The facility constructed and launched Multi-missiles and, if a Tiberium Waste Facility had collected enough Tiberium veins, a chemical missile.
By the time of the Third Tiberium War, a missile silo was reintegrated into the Temple of Nod.
