Mark-II SPI Armor

The Semi-Powered Infiltration Armour, colloquially called "SPI Armour", was an armor system used by the United Nations Space Command 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 Armor 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. It features Special photo-reactive panels that mimic the surrounding textures, effectively being the UNSC equivalent to the Covenant Active Camouflage systems. It has been described as part legionnaire mail, part tactical body armour, and part chameleon by both Tom-B292 and Dr. Halsey.[1] The helmet is similar in appearance to the Halo 3 EVA permutation.

SPI Mark I

The SPI armour 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 armour, it could only take a few glancing blows before failing[2]. The armour featured full body armour with an enclosed helmet and HUD, and a supply of breathable atmosphere; though only enough for 7 minutes, compared to the MJOLNIR armour’s endurance of 90 minutes. It is also equipped with a cushioning layer of liquid nanocrystals that provided more ballistic protection than three centimetres of Kevlar diamond weave without the bulk. The featured photo-reactive panels gave the Spartans of Alpha Company active camouflage. The camouflage patterns, however, shifted irregularly and imperfectly, which made the photo-reactive panels unmatched against the Covenant Elites Camouflage technologies. This was because the SPARTAN III program probably didn't allow enough time, to get the photo-reactive panels working properly. Another concern was the budget spent in making the suits.

SPI Armour Mark II

The SPI armour Mark II was a more advanced version of the SPI Mark I, first used by the drill instructors of Beta Company and then by the Spartans of Beta Company. They had new photo-reactive coating to boost camouflaging properties. There were also numerous experimental refits to the gel ballistic layers, upgraded software suites, and other functions. Although the new photo-reactive coating could mimic a wide range of EM (Electro-Magnetic) radiation, it was still sensitive to overload, which is why it takes the suit a few moments to reset after a flash-bang or plasma hit for example[3].

It was proposed in 2537 for Alpha Company, but the request was denied because the armour was over budget. After the "successful" operation of Alpha Company, the Mark II armour was approved for mass production.

After the augmentation of Gamma Company, small adjustments were installed into the SPI Armour Mark II.

Advantages vs. MJOLNIR Armour

  1. The armour is significantly cheaper and easier to mass-produce.
  2. Includes special photo-reactive panels that act as an active camouflage for the wearer.
  3. It could be transported easily, because it is not as thick or heavy as the MJOLNIR armour.
  4. It is more flexible to move by will of the wearer.
  5. The armour requires less physical enhancements compared to the MJOLNIR armour making it more versatile to other would-be users.

Disadvantages vs. MJOLNIR Armour

  1. Has no energy shield that the SPARTAN-IIIs required, considering the amount of danger the Spartan-IIIs face.
  2. Does not give the SPARTAN-IIIs the same amount of enhanced strength, speed, and agility as the MJOLNIR does for SPARTAN-IIs.
  3. It stresses more teamwork on the Teams, to take down enemy threats.
  4. After long usage, the Semi-Powered Infiltration Armour tends to heat up and can become very uncomfortable.
  5. Since the AC plates take time to recover, after explosions such as a flash bang grenade and plasma hits, the SPARTAN-III is visible until the plates recover.
  6. Is made of a less dense alloy than MJOLNIR armour as Kelly-087 managed to dent Holly's chest plate with her fist on the planet Onyx.

Notes

  • Some screenshots released by Bungie lead to fans speculating that they would be able to use SPI armour in Halo 3. However, the armour was later determined to be Mark VI MJOLNIR Powered Assault Armor/V variant. The name and changes in appearance are purely cosmetic, however, having no impact on gameplay. This has been confirmed by Bungie.
  • For all intents and purposes, SPI armour is simply a less-powerful version of MJOLNIR armour. It was meant to give the wearer maximum protection at the minimum cost, so many of the original armour features (for example, shields) were left out.
  • The SPI armour bears a striking resemblance to Halo 3's EVA armour.
