{{Status|Canon}}

Pilot-issue versions of these vacuum suits were used by the [[FSS-1000 Sabre]] crews who boarded the [[Covenant corvette]] ''[[Ardent Prayer]]'' during [[Operation: UPPER CUT]]. Personnel working aboard UNSC refit stations such as ''[[Anchor 9]]'' also used similar vacuum suits.<ref>'''Halo: Reach''', campaign level ''[[Long Night of Solace (level)|Long Night of Solace]]''</ref> Marine-issue vacuum suits were used by [[Avery Junior Johnson|Sergeant Johnson]] and his squad as they neutralized the unsecured data of the {{UNSCShip|Circumference}} in orbit above [[Reach]].<ref>'''Halo: The Fall of Reach''', ''page 313''</ref> Vacuum combat suits are also used during atmospheric missions where atmospheric hazards, such as nearby [[glassing]], are present. This was seen during the [[Battle of Asźod]], where UNSC Marines assigned to the {{UNSCShip|Pillar of Autumn}} used vacuum combat suits.<ref>'''Halo: Reach''', campaign level ''[[The Pillar of Autumn (Halo: Reach level)|The Pillar of Autumn]]''</ref>

A model of vacuum suit used by UNSC Marines in the early years of the war was more clearly distinct from ground-based BDUs, featuring a green full-body suit, with olive-drab armor plates, and a helmet equipped with a [[Heads-up display|HUD]] and [[COM]] systems.<ref name="genesis">''[[Halo Wars: Genesis]]''</ref> They were used by the teams sent to clear the NAV database of the {{UNSCShip|Prophecy}} during the [[Harvest Campaign]] in [[2531]].{{Ref/Reuse|genesis}}

===Black bodysuit===

This bodysuit is a form-fitting suit of polymer body armor that has systems that mask the infrared signature of the wearer, as well as creating a comfortable environment. The suit is fully sealed, and has an oxygen reserve of 15 minutes. The helmet has encrypted communications gear and a HUD, along with thermal sensors and motion detectors. Unfortunately, the suit's general complexity leads to complications. Over prolonged periods of time the suit will become very uncomfortable to wear, and is difficult to repair in the field.<ref>'''Halo: The Fall of Reach''', ''page 79''</ref>

These suits were used by the [[SPARTAN-II program|SPARTAN-IIs]] in several missions before they got their [[MJOLNIR Powered Assault Armor/Mark IV|MJOLNIR Armor]].

The [[MJOLNIR Powered Assault Armor]] system utilized by the SPARTAN-IIs has 90 minutes of breathable atmosphere.<ref>'''Halo: The Fall of Reach''', ''page 120''</ref> The vacuum capabilities of the armor were demonstrated during the initial phase of the [[Battle of Earth]], where [[John-117]] utilized the armor effectively in vacuum combat. As well as being completely sealed, the armor can prevent the [[Spartan]] wearer from burning up in a planet's atmosphere. Later in the battle of Earth, the [[Master Chief Petty Officer|Master Chief]] fell through [[Earth]]'s atmosphere into the jungle of [[Kenya]] and survived, although he did use part of the [[Forerunner]] [[Anodyne Spirit|Dreadnought]] as a heat shield.<ref>'''[[Halo 3]]''', campaign level ''[[Arrival]]''</ref><ref>'''Halo 3''', campaign level ''[[Sierra 117]]''</ref>

The [[Covenant Empire|Covenant]] also use vacuum suits,<ref name="Reach">'''[[Halo: The Fall of Reach]]''', ''page 310''</ref>  such as the blue-and-black suits worn by [[Kig-Yar Ranger]]s. [[Sangheili Ranger]]s and other special operations units utilize special vacuum-enabled [[Combat harness|Combat Harnesses]], such as the [[Assault Harness]], [[Flight Harness]], [[Ascetic Harness]] and [[Commando Harness]].
