Both Nod and GDI share these same structures

Construction Yard

The Construction Yard is where all life begins. It allows the player to build other structures, so defending it should be a top priority of any succesfull commander. In some missions, the player starts with an MCV, which can be deployed into a Construction Yard. In other missions, the Construction Yard is already placed.

Tiberium Refinery

The Refinery converts Harvester loads of Tiberium into credits for the player. It also stores a certian amount of Tiberium. Once a Refinery is full, silos must be created in order to store excess Tiberium. If there is no available storage capacity at a Refinery or silos, excess Tiberium is lost.

Electromagnetic Pulse (EMP) Cannon

The EMP Cannon can fire a high powered blast of Electromagnetic energy that renders any mechanised vehicles inoperative for a short period. Any vehicle or structure caught in the blast is disabled until the effect wears off.
