Tech Structures
Several neutral tech structures are available on the battle fields of
Tiberian Twilight. Unlike in previous games, these structures may not be destroyed, instead they change ownership depending on which team has the larger number of forces in the vicinity of the structure. A tech structure may either be controlled by GDI, or by Nod, or by nobody. If a Nod unit moves into the vicinity of a GDI-controlled, but otherwise undefended structure, the structure will first become neutral and then fall under Nod control. Attacking a structure that is controlled by an enemy quickens the enemy's loss of control.
Two of the tech structures are defensive turrets which may fire at you if they are held by the enemy; in that case attacking them in force may be a good tactic to minimize casualties. All other structures may be captured at leisure if there are no enemy units nearby, even by a single Engineer or Raider.
