;Photoreactive panels: The outer shell of the SPI armor comprises a series of lightweight laminate plates with a photoreactive coating.<ref name="HM"/> While matte gray when inert,<ref name="g141"/> the photoreactive panels act as [[active camouflage]] when active,<ref>'''Halo: Ghosts of Onyx''', ''page 165''</ref> effectively blending the wearer with their environment.<ref name="goo14"/> The coating also renders the wearer nearly invisible to infrared and passive light-gathering systems.<ref>'''Halo: Last Light''', ''page 95'' (Google Play edition)</ref> Since the photoreactive plates take time to recover after explosions such as a [[flashbang grenade]] and [[Plasma weaponry|plasma]] hits, the wearer is visible until the plates recover.<ref name="goo113"/> With the exception of the [[Headhunters]]' suits, the SPI armor does not feature energy field-based active camouflage systems like those of the Covenant.<ref name="head212"/>

This variant has a helmet design that is similar to [[GRENADIER-class Mjolnir|Grenadier]]. [[Mark-G313]] wore this suit during [[Operation: JOVIAN WHISTLE]].

The SPI armor is referred to as "PR" twice in ''Halo: Ghosts of Onyx''.<ref>'''Halo: Ghosts of Onyx''', ''page 87'' (''"...the flaws in their Mark-I PR suits..."'')</ref><ref>'''Halo: Ghosts of Onyx''', ''page 141'' (''"...and pulled on the PR leggings."'')</ref> No context or explanation is provided for this alternate designation, although it is possible that the suit was known as "PR" (likely an acronym for "PhotoReactive") in an earlier revision of the novel's manuscript and that the presence of the two mentions in the final book is an editing oversight.
