Wall (Tiberium Wars)
Walls are a passive defensive barrier used by both the GDI and Nod in Tiberium Wars. Unlike previous games in the Tiberium series, walls cannot be built by players. A Scrin variation of the structure exists in the game but is left unused.
The concrete wall has seen service as a defensive barricade for almost a century. Simple and reasonably priced concrete was the main static defense for many bases since the First Tiberium War. They are vulnerable to explosive and cannon based attack, but their thickness barred C4 from effective use against them.
