Semi-Powered Infiltration armor: Difference between revisions

I've moved the Headhunters cover art to the end of the gallery. Although it is officially endorsed, it is fan art nonetheless.

The '''Semi-Powered Infiltration Armor''', (abbreviated '''SPI armor'''), is an experimental [[armor]] system used by the [[United Nations Space Command]]. It was developed for use by the [[SPARTAN-III program|SPARTAN-IIIs]].

==Description==
==Overview==
Though more advanced than the [[Orbital Drop Shock Trooper]]s' [[ODST armor|ballistic body armor]], it is far less advanced and less powerful than the [[MJOLNIR Powered Assault Armor]] used by the [[SPARTAN-II Program|SPARTAN-IIs]]. Its main benefit is that it is drastically cheaper to produce than the MJOLNIR armor. The SPI armor was designed with an emphasis on stealth rather than on raw power. It features [[Photoreactive panel|special photo-reactive panels]] that mimic the surrounding textures, effectively being the UNSC equivalent to the [[Covenant Empire|Covenant's]] [[Active Camouflage|active camouflage]] systems. It has been described as part "legionnaire mail, part tactical body armor, and part chameleon" by both [[Tom-B292]] and [[Catherine Elizabeth Halsey|Dr. Catherine Halsey]].<ref>'''Halo: Ghosts of Onyx''', ''page 16''</ref>

==SPI Armor Mark I==
==Versions==
===Mark I===
The SPI Armor Mark I was used by the SPARTAN-IIIs of [[SPARTAN-III Alpha Company|Alpha Company]]. It featured hardened plates and photo-reactive panels. Though advanced compared to standard UNSC infantry armor, it could only take a few glancing blows before failing.<ref>'''Halo: Ghosts of Onyx''', ''page 14''</ref> It featured full body armor with an enclosed helmet and [[heads-up display]], and a supply of breathable atmosphere; though only enough for [[List of "seven" references in Halo|seven]] minutes, compared to the MJOLNIR armor’s oxygen supply of ninety minutes. It was also equipped with a cushioning layer of liquid nanocrystals that provided more ballistic protection than three centimeters of [[wikipedia:Kevlar|Kevlar]] diamond weave, without the bulk. The featured photo-reactive panels gave the SPARTANs of Alpha Company a rough equivalent to active camouflage. The camouflage patterns, however, shifted irregularly and imperfectly, which made the photo-reactive panels inferior compared to the Covenant's active camouflage technologies.

==SPI Armor Mark II==
===Mark II===
The SPI Armor Mark II was a more advanced version of the SPI Mark I, first used by the drill instructors of [[SPARTAN-III Beta Company|Beta Company]], and then by the SPARTANs of Beta Company. They had new photo-reactive coating to boost their camouflaging properties. There were also numerous experimental refits to the ballistic gel layers, upgraded software suites, and other functions. Although the new photo-reactive coating could mimic a wide range of electromagnetic radiation, it was still sensitive to overload, so the wearer would still be vulnerable for several seconds after a flashbang or [[plasma]] hit while the panels reset.<ref>'''Halo: Ghosts of Onyx''', ''page 113''</ref>

*It has no [[energy shielding]] system, unlike the SPARTAN-IIs' MJOLNIR Mark V and Mark VI models, making the user far more vulnerable to enemy fire and a major contributor to the high fatality rate of the SPARTAN-III's. However, the SPARTAN-III [[Headhunters]] are known to be equipped with energy shields for their armor, due to their elite nature and value. However, power must be drawn from the energy shields to recharge the suit's active camouflage module, and current information indicates only the Headhunters are equipped with shields.

*Since the photo-reactive plates take time to recover after explosions such as a [[flashbang grenade]] and plasma hits, the SPARTAN-III is visible until the plates recover. With the exception of the Headhunters' suits, the SPI armor does not feature true active camouflage systems.
