Prototype Mobius suit

Mobius Suit
The Mobius Suit is a personal powered suit that somewhat resembles a space suit. It was designed by Dr. Ignatio Mobius for use in handling Tiberium for experimentation. Dr. Mobius’s daughter Sydney has since added additional armour and other assault type weaponry to the suit in an effort to transform the suit into an actual combat weapon. Both Sydney and Ignatio use the suit, though they are the only people in the world who know how to operate it.

Concept artwork of GDI Zone Troopers in Tiberium Wars Suggest that they may be using advanced versions of the mobius suit, although this is currently only speculation.
