User:Subtank/Semi-Powered Infiltration Armour

The Semi-Powered Infiltration Armor, colloquially called "SPI Armour", was an armour system used by the UNSC that was developed for the Spartan-IIIs. Though more advanced than the ODST Ballistic Body Suits, it was far less advanced, and less powerful than the MJOLNIR Armour used by the Spartan-IIs. Its main benefit was that it was drastically cheaper to produce than the MJOLNIR armour. This armour was designed with an emphasis on stealth rather than raw power in which it sports special photo-reactive panels that mimic the surrounding textures, effectively being the UNSC equivalent to the Covenant Active Camouflage systems.
