Storm was an infrequent specialist combat role for Sangheili serving in the Covenant, acting as shock-troopers for the original Empire. Storm have become the usual military backbone of the Covenant remnant factions.
Storm are specialized shock-troopers that can serve in assault roles, marksmen roles, and scouts. Sangheili Storm often lead lower-ranking Unggoy and Kig-Yar on the battlefield while reporting to higher-ranking Sangheili Commanders or Zealots. Following the Great Schism many Storm-class Sangheili joined the Swords of Sanghelios, while others joined Jul 'Mdama's Covenant or became mercenaries. While Storm troops served as specialized shock units under the original Covenant, post-war Storm troops would serve a more generalised infantry role similar to Sangheili Minors.
Like Rangers and Zealots, Storm-class Sangheili have their own internal ranking structure. Sangheili Storm clad in blue harnesses are the equivalent of Minors. Storm units in red harnesses are analogous to Majors. Ultras may be equipped with white-and-red harnesses. Sangheili Storm with command status wear golden harnesses, making them similar to Field Masters. Green-armored Sangheili Storm may be Sangheili who temporarily allied with Arbiter Thel 'Vadam when the Great Schism started but left him afterwards due to ideological differences.
The Sangheili Storm often wear the Storm harness, Lodam Armory's first fully in-house armor system. The harness is simple, sleek, and efficient. The helmet covers the full span of the face, while the harness proper has form-fitting greaves. Unlike the more thoroughly protective combat harness, the non-standard Storm armor salvaged by remnant factions, such as Jul 'Mdama's Covenant, tends to leave its wearer's arms exposed. However, the full set of the Storm harness is used by the Swords of Sanghelios which has an all-encompassing body glove similar to the combat harness. The Storm harness is most often issued in blue, though green, red, white, and gold versions also exist. The Sangheili Storm affiliated with the Swords of Sanghelios have crimson harnesses with ivory accents.
Sangheili Storm within Jul 'Mdama's Covenant were often armed with Type-55 storm rifles and Type-51 carbines, while using Type-33 Needlers or Type-25 plasma pistols as sidearms. Occasionally they wielded explosive weaponry like the Type-33 fuel rod gun or Type-50 concussion rifle. They were occasionally seen using Type-1 energy swords. Sangheili Storm on Requiem sometimes used Forerunner Z-110 boltshots. By October 2558, Many Sangheili Storm began to make use of Type-54D plasma pistols, Type-56D Needlers, and Type-57B carbines, as well as Type-58 fuel rod cannons and Type-53 Plasma Casters. In War Games simulations aboard the UNSC Infinity Sangheili Storm are sometimes equipped with Type-27 beam rifles and Z-180 Scattershots.
Sangheili Storm typically carry only storm rifles and Covenant carbines and very rarely wield energy swords throughout the campaigns. Their shields are weaker and they are more likely to make mistakes in combat than the higher ranking Sangheili, especially on lower difficulties.
