Info and Specs:

The Communications Center will give you an overhead view of the battlefield when fully powered. Many buildings like your communications center can be enhanced by adding upgrades to one of the available pods.

The GDI barracks are used to train all types of soldiers, from light infantry to medics and engineers. However, nothing can train and advance your troops' abilities better than battlefield experience.

Armed with a rapid fire vulcan cannon, the Vulcan Cannon Guard Tower is ideal for defending your base from enemy troops.

Another kind of a GDI guard towers is the Rocket-Propelled Grenade Launcher. It is used best against tanks and armor.

This SAM Guard Tower automatically launches long-ranging missiles at enmy aircrafts. Slower moving or hovering aircraft will fare the worst against this defensive structure.

This Firestorm building is the utimate defense.  It generates a huge force field that keeps unfriendly units (and some weapons) out of your base.  Westwood has not decided how this structure will work (and be destroyed) in detail.

Info and Specs:

The Hand of NOD, if you don't remember from the first C&C game, trains NOD infantry.  It's like a NOD barracks.

This building is just like the Gap Generator in Red Alert.  It hides buildings and units around it within a certain radius.   However, your enemies' units would be able to see the cloaked buildings if they are close enough

This building is back form the original C&C and of course it's better.  It will have the usual nuke, but only better.  There will be other special weapons availible be I'm unsure at this moment.

This laser fence will keep enemy units from going into your base.  It's like GDI's concrete wall but this is more advanced, and it requires more power.  Any infantry or lightly armoured unit will be gone almost in a instant if they think they are tough enough to go though this fence.  Tanks might survive, but it won't do much good after.

This building is known as the Obelisk or the Obelisk of Light.  It will direct a red penatrating laser at any unfriendly units that comes to range.  It usually takes out men in one shot, and mechinary in 2 to 4 shots.   It's now improved to attack air units also.

If you have played C&C: Tiberian Dawn ot Red Alert, you'll recognize this structure.  Simply, all it does is it protects your base from air attacks by firing missles at the helicopters/planes.  It's most vonluable when it's opened and poped-up.

Info and Specs:

Well, here's another interesting structure.  It's found in most of the bridges that will be in the TS Game.  When a bridge is shot down, a player will be able to fix it by sending an engineer into this little house.
