Sangheili combat harness
 Development and History
The combat harness is worn by the majority of infantry ranks from Sangheili Minor to Ultra and Zealot, with the damage each can take and the armor's shielding increasing in power with rank (with the exception of Stealth Sangheili), and comes in a variety of colors denoting said rank. The armor boosts the strength and speed of the wearer in a similar fashion to the SPARTAN's MJOLNIR powered assault armor, although to which degree is unknown. Some versions have active camouflage built in and others have flashlights, other versions have an energy dagger built into the gauntlet. Its primary emphasis, to be iconic and inflict psychological trauma, can be linked back to the martial/physical pre-eminence of the Sangheili people. This helmet has remained unchanged for eleven hundred cycles, and the thoracic cage has remained unchanged for fifty generations.

 Helmet characteristics
The helmet is largely angular, featuring a set of spikes at the rear of the helmet and a pair of cheek guards. It features a metal plate guarding the jaw.
 Shoulder pauldron characteristics
The Shoulder Pauldron is a set of overlapping plates that spike both upwards and downwards and to each side.
 Thoracic cage characteristics
The Thoracic Cage is made up of a pair of plates over each side of the chest with a gap and a pair of rectangular lights heading downwards on each side.
 Changes in design
 Halo: Combat Evolved
The armor used by the Elites in Halo: Combat Evolved has a few differences from the armor used in later games, such as some Elites have a "curled back" headpiece, different thigh armors, and smaller shoulder pieces. They also have armor with a three-pronged design. In addition, they have orange glowing sections on their arms and legs, which often give away their position. Their eye color is also the same as their armor color, for example: a Minor with blue armor will have blue eyes.
 Halo 2
In Halo 2, there are no curled headpieces and the eyes are not the same color as the armor, rather a dark purple or black color. Also, the shoulder pieces are larger than in the previous game. They also have glowing orange sections on the backs of their legs and on their arms which act as shield indicators, glowing brightly when the shield is fully charged and dimming or going out altogether depending on shield level.
 Halo 3
In Halo 3, the Elite's armor is again altered. The armor now includes even larger shoulder pieces, longer and more numerous spikes on the headpiece, and a small tube connecting to each bottom mandible guard. The tube is only included in the Halo 3 incarnation. There is also a horizontal light on the chestpiece. The large orange shield indicators are replaced by two small green lights on the Elite's back and on their chest plate, which are dull when the shield is fully charged and glow bright when the shield is depleted.
 Halo: Reach
In Halo: Reach, the combat harness is different from the earlier iterations in a number of ways. The other types are also much more varied, depending on the Elite's rank or specialty. Only the Elite Minors' armor greatly resembles the Combat Harness seen previously. Another addition to the armor is the energy dagger which emits from the wrist gauntlet.
The Sangheili HUD compass has Covenant markings instead of cardinal directions. Night vision is also purple, as opposed to the green used by Spartans. The Sangheili HUD also features a target tracking system when used with compatible (Covenant) weapons.
 Halo 4
Multiple variants of the combat harness are introduced in Halo 4. There appears to be much less armor covering the bodysuit and the forearms are protected by only the bodysuit or even completely exposed in some cases. Of the variants revealed so far, the bodysuit underneath does not cover the hands at all (except for the Ranger variant), unlike certain previous iterations where the bodysuit includes gloves.
