"Command & Conquer" gameplay typically requires the player to construct a base and acquire resources, in order to fund the ongoing production of various types of forces with which to assault and conquer the opponent's base. All available structures of the faction chosen by the player are constructed on-site at so-called "construction yard" - which typically begin as large-sized vehicles capable of deploying themselves into the aforementioned construction yards, called MCVs or Mobile Construction Vehicle. When a construction yard has finished building a new structure, the player can select a spot near to a preexisting structure in order to place it, where the prefabricated building will rapidly unfold in a distinctive manner.
