EVA-class Mjolnir
From Halopedia, the Halo wiki
EVA Armor is the new SPI Armor of Halo 3. The EVA stands for Extra Vehicular Activity. It has been describes as space-suit like, and looks especially cool in a bad-ass Neil armstrong way. One small step for man.... The armor is fully customizable and appears to be completely cosmetic. But, as the article says, one variant of the EVA armour is the CQB, or Close-Quarters Battle, armour.
