Unggoy combat harness
From Halopedia, the Halo wiki
The Unggoy combat harness is a type of body armor and environmental suit issued to the Covenant's Unggoy warriors. It provides basic protection from hostile fire and the elements and is also equipped with a breathing apparatus for the Unggoy.
The gas is stored in extremely cold tanks inside the suit, and is provided to the user through a breathing mask that covers over half of the alien's head. The backpack attached to a Grunt's back contains a methane tank. Attached to every Grunt's wrist is a readout (measured in Covenant units) of the amount of methane left in the Grunt's pack. When the tank gets low, a resupply of methane must be found quickly or the Grunt will suffocate. The suit also displays the color of the Grunt's rank. The breathing mask of the Unggoy also makes speech difficult for them, as it muffles their words.
In addition to its life support role, it is equipped with armor. This armor can withstand limited amounts of fire, especially from energy weapons. The M6D magnum is capable of easily cracking through the armor and is considered by some to be the standard weapon for such actions. The armor piercing rounds of the MA5 series are also potent weapons against the harness. As well as defending against projectiles and plasma, it prevents a limited amount of fall damage to its user, like its Sangheili counterpart. Despite this, most variants are vastly inferior to the other types of armor adorned and used by the Covenant, no doubt due to the costs required to produce the suits for the extremely large population of Unggoy soldiers. Some variants are also equipped with helmets, active camouflage, a methane-filled breathing apparatus, methane fueled thrusters, and even energy shielding.
Note: Most of the labels in the following list are descriptive rather than official.
Point tank: This variant of harness is used by Unggoy of nearly all ranks and roles. Notable ranks and roles to use this harness are Unggoy Minor, Unggoy Major, Unggoy Ultra, Unggoy Heavy, and Special Operations Unggoy.
Imperial harness: The harness used by Imperials in Jul 'Mdama's Covenant was also issued to some troops during the Human-Covenant War, and is more resilient than the Unggoy Storm version. The helmet is a heavy armor faceplate which protects the whole face. The methane tank resembles Balahoan octopoda. The harnesses have been seen in orange, red, green, silver, and blue.
Slim-stock tank: The Heavies of Jul 'Mdama's Covenant wear a helmet with full-face protective rebreathers, enhanced optical sensors with optics articulators, and ultra-dense battle harnesses that has a slim-stock tank with analog eye sockets of Unggoy predators. The harness is issued in orange, blue, silver, green, and magenta. The combat harness also allows for the Heavies to use the methane tank as a makeshift thruster pack, allowing for easy access in various terrains.
Wide-stack methane supply harness: The Unggoy Ranger harness has a wide-stack methane supply tank with an EVA thruster pack on it, this allows the user to freely navigate low-to-zero gravity environments. The helmet has a twin-filter rebreather so the wearer does not suffocate in the harsh environments.
There are two versions of the Unggoy ranger suit, both of which cover the entire Unggoy body and have hock-mitigators on the feet. The version with a more smooth surface is designed to withstand extreme temperatures, low-to-zero gravity, and other rigors found in the vacuum of space. The second version has more layers.
Unggoy Storm harness: In a effort to increase field of view, the Unggoy Storm helmet includes a nose-placed rebreather somewhat resembling the diving apparatuses used on the Unggoy homeworld of Balaho. The harness has a pressurized methane tank, with a filter actuator to help keep the tank working.
The harness is issued in orange, blue, violet, green, yellow, and red. The harness also allows for the Unggoy to use the methane tank as a makeshift thruster pack, allowing for easy access in various terrains.
Deacon outfit: Deacons wear tunics mixed with the harness point tank harness.
Artifact retrieval harness: Unggoy attached to artifact retrieval groups are given a harness with two tubes on their back. Heretic Unggoy in Sesa 'Refumee's heretic faction wore these when they rebelled against the Covenant.
Plasma-ignited methane tank harness: This harness is specially made for Suicide Unggoy.
