Allows a Commander to store more ore
The ore silo was a cylindrical open-topped structure that was designed to keep superheated excess raw ore for later processing and manufacturing of units. The ore was collected via pipes to the nearest ore refinery, where the raw material was processed, as well as War factory structures, where the smelted ore was utilized.
In the Tiberium Universe, it formed a basis for the Tiberium silo. In Red Alert Universe however, due to advances in processing and storage technology, silos were no longer needed to store excess ore in the Third World War.
