A Spartan-III in Mark-II SPI Armor.

The Semi-Powered Infiltration Armor, or SPI Armor, is an experimental armor system used by the United Nations Space Command. It was developed for the SPARTAN-IIIs.

Description

Though more advanced than the Orbital Drop Shock Troopers' ballistic body armor, it is far less advanced and less powerful than the MJOLNIR Powered Assault Armor used by the 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 special photo-reactive panels that mimic the surrounding textures, effectively being the UNSC equivalent to the Covenant's active camoflauge systems. It has been described as part "legionnaire mail, part tactical body armor, and part chameleon" by both Tom-B292 and Dr. Catherine Halsey.

SPI Armor Mark I

The SPI Armor Mark I was used by the Spartan-IIIs of 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.

SPI II armor

The SPI Armor Mark II was a more advanced version of the Mark I SPI, first used by drill instructors Company Beta, and then by the Spartans of Beta Company. They had photoreactive new coating to increase its camouflage properties. There were also numerous experimental reinstall the layers of ballistic gel, updating software packages, and other functions. Although the photo-reactive new coating could mimic a wide range of electromagnetic radiation, remained sensitive to overloading, so users will remain vulnerable for several seconds after you hit a flashbang or plasma panels, while the recovery.

It was proposed in 2537 for Alpha Company, but the request was denied because the armor was over budget. After pyrrhic victory Alpha Company in Operation: Prometheus, the Mark II armor SPI was approved for mass production. After increasing the company Gamma, minor adjustments were installed in the SPI Armor Mark II.

Ventajas

1. La armadura es mucho más barato y más fácil de producir en masa que la armadura Mjolnir.
2. Incluye reactivos paneles foto- que actúan como un camuflaje activo para el usuario.
3. Es más fácil de transportar, ya que no es tan voluminosa o tan fuerte como la armadura Mjolnir.
4. La armadura tiene un sistema de enfriamiento eficaz y es significativamente más difícil de detectar, incluso con escáneres térmicos. Este sistema puede fallar durante períodos prolongados de uso, sin embargo.
5. usuarios SPI armadura no necesita un técnico para ayudarles a ponerse la armadura.
6. La armadura requiere el aumento de menos físico en comparación con la armadura MJLONIR, lo que permite a los usuarios, además de SPARTAN-IIIs para operar armadura.

Disadvantages

1. You do not have the energy shield system, unlike-II 'MJOLNIR Mark V and Mark VI SPARTAN models, making the user more vulnerable to enemy fire and a major contributor to the high mortality rate of SPARTAN-III. However, the SPARTAN-III headhunters are known to be equipped with energy shields for armor, due to its nature and value of elite. However, power must be extracted from energy shields to recharge module Camoflauge active demand, and current information indicates only the headhunters are equipped with shields.
2. Does not force improved SPARTAN-IIIS, speed or agility, as the MJOLNIR does for its users.
3. Since the reactive-picture boards time to recover after the explosions, like a flashbang grenade and hits the plasma, the SPARTAN-III is visible until the plates to recover. With the exception of headhunters' suits, not real armor SPI Camoflauge systems active.
4. It is made of a less dense alloy MJOLNIR armor: Holly Kelly-087-G003's dented plate chest with his fist in his first encounter with the SPARTAN-IIIs.
5. The SPI armor is not waterproof or airtight, unlike the Mjolnir armor.
6. The SPI armor can not be used for long periods of time without the cooling system fails.
7. The SPI armor has an air supply for only seven minutes, while the MJOLNIR has a supply of air for ninety minutes.
8. It lacks the ability to support on board an artificial intelligence construct, unlike the Mark V, Mark VI, and Black models in the Mjolnir armor.

Trivialidades

• Algunas capturas de pantalla en libertad por Bungie llevó a los fans especulaban que sería capaz de usar la armadura SPI en Halo 3. Sin embargo, la armadura se reveló más tarde a ser la variante EVA MJOLNIR.
• El casco de seguridad en Halo: Reach tiene un parecido notable a la armadura SPI.
