-Flame Turret (Basic Anti Inf) - short range, but good damage and splash
-Cannon Turret (Basic Anti Tank, not pictured) - similiar to GDI Turret
-Missile Turret (Basic Anti Air)
-Obelisk of Darkness - shoots air and ground targets but has no special anti inf laser like the Nod Obelisk of Light
And yes, Flame Turret is going to get rescaled, its a bit to big right now.
