	Barracks
		Cost: Low Armor: Medium Power: Low	Your infantry are trained here and this structure also allows you to build guard towers and watch towers

	GDI Power Plant
		Cost: Low/Medium Armor: Low/Medium (Provides Power)	These structures provide electricity to your base. If there is not enough power for all the structures in your base, they will slowly take damage and units and strucures would build more slowly. Also, you will lose power to many things like communication center and most base defenses. You can cut off power to certain ctructures when they are not needed.

	Power Plant Upgrades
		Cost: Low Armor: NA (Provides Power)	The GDI power plants have extra modules which can be added for a higher power output. However, it is still best to build lots of power plants, each with only one module. This is because if a power plant with three modules is destroyed, you will lose a lot of power, but if only one module is lost, it's not as bad.

	Communications Center
		Cost: Medium? Armor: Medium? Power Medium?	The GDI Communications Center provides a radar map and can also be upgraded with the two different modules described below.

	Threat Evaluation System
		Cost: Low? Armor: NA Power Medium?	This upgrade module for the Communications Center makes your base defense systems work more efficiently, by all concentrating their firing on the biggest enemy threat.
	SAT Uplink
		Cost: Medium? Armor: NA Power None?	The Satellite Uplink module for the Communications Center allows you to view the whole map, without first exploring it.
	Upgrade Center
		Cost: High? Armor: Medium? Power Low?	This building allows you to build the two upgrade modules below, the Ion Cannon Uplink and Hunter Seeker Control.
	Ion Cannon Uplink
		Cost: High Armor: NA Power High?	This upgrade module for the Upgrade Center allows you to use the devestating Ion Cannon. This fires a concentrated beam of chraged ions towards the enemy, destroying everything in seconds, but only affecting a narrow area. It is free once the module has been built, but can only be used after a certain time interval. I am a bit confused about this module because in PC Gamer, they said the buailing above was the Ion Cannon Control. Maybe you need the uplink and the control?

	Seeker Control
		Cost: Medium Armor: NA Power Medium?	This upgrade module for the Upgrade Center allows you to build Hunter Seeker Droids, which you can read about in the GDI Infantry Units section.
	Tech Center
		Cost: High? Armor: Medium? Power Medium?	The technology center allows you to build more advanced units and structures.
	Orca Pad
		Cost: Medium/High Armor: Medium Power: Medium	These are needed to build Orca helicopters. They can land on these to re-arm and be repaired, although you don't need one for each helicopter. It is best to have as many as possible to speed up reloading. Carryalls and Orca Transports do not require landing pads as they do not need reloading.

	Component Guard Tower
		Cost: Low/Medium Armor: Heavy Power: High?	These can have either SAM launchers (for attacking air units), Vulcan Cannons (for attacking infantry) or RPG launchers (for attacking land units) fitted.
	SAM Upgrade
		Cost: Low Armor: NA Power High?	This upgrade for the Component Guard Tower is equipped with Surface-to-Air missiles, to defend your base from Nod Banshees and Helicopters.
	Vulcan Cannon Upgrade
		Cost: Low Armor: NA Power High?	The Vulcan Cannon upgrade for the Component Guard Tower is best used for killing infantry.
	RPG Launcher Upgrade
		Cost: Low Armor: NA Power High?	This upgrade for the Component Guard Tower is a Rocket-Proppelled-Grenade launcher, excellent for destroying attacking armored vehicles.
	Transport Bay
		Cost: Medium? Armor: Low? Power Low?	The transport bay is where huge drop ships drop off extra units which I think, you can order, if you have a lot of money but not many units.
	Firestorm Defense
		Cost: High Armor: Heavy Power: Very High	This shield surrounds your base, protecting it from the enemy and preventing air or ground attacks. It only works for a short time before overloading, so only turn it on during an attack. This structure is the generator for the firestorm defense. To function, you also need to build emitters, as described below.
	Firestorm Defense Emitters
		Cost: Medium Armor: Heavy Power: Very High	These 'wall sections' are the emitters for the firestorm defense. I'm not sure if you need to build them in a wall surrounding your base, or just a few in the center. However you use them, they can only be damaged by missiles and shells, which only do 2% of their normal damage.
