We need to establish a base in this area. Unfortunately, so does Nod. They have already put up Obelisks to guard the only way in. We need you to cut the power to the Obelisks before our MCV arrives. With the MCV, set up a base and eliminate the Nod forces. - Mission briefing
GDI needs to establish a base in the region and has sent an MCV to begin base construction. However, Nod also needs one in the same area and has set up Obelisks along the route the MCV is taking. GDI has sent two Commandos to deactivate the Obelisk's power supply and establish the base to eliminate the Nod forces in the area.
