'''Vacuum Suits''' are used by both the [[UNSC]]<ref name="Reach"/> and the [[Covenant Empire|Covenant]]<ref name="Reach">'''[[Halo: The Fall of Reach]]''', ''page 310''</ref> for [[extra-vehicular activity]] in outer space, intended to protect the wearer from the effects of vacuum and prevent asphyxiation. They also provide protection from dust and other particles which could damage the user and their equipment. Vacuum suits are completely sealed, and come with an extra supply of [[oxygen]], or whatever other gas the user breathes.

== UNSC ==

The [[UNSC]] utilizes several types of vacuum suits. 

The suits worn by members of the [[UNSC Marine Corps]] have a green 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> These suits were used by [[Avery Junior Johnson|Sergeant Johnson]] and his squad as they neutralized the unsecured data of the [[UNSC Circumference|UNSC Corvette ''Circumference'']] in orbit above [[Reach]].<ref>'''Halo: The Fall of Reach''', ''page 313''</ref> They were also used by the teams sent to clear the NAV database of the {{UNSCShip|Prophecy}} during the [[Harvest Campaign]] in [[2531]].<ref name="genesis"/>

Bulky, black vacuum suits with a compartmentalized design and [[Sealant foam|self-sealing foam]] injectors were used by [[Staff Sergeant]]s [[Avery Junior Johnson|Johnson]] and [[Nolan Byrne|Byrne]] during humanity's very [[Skirmish on Minor Transgression|first combat encounter]] with the Covenant.

One type of vacuum suit worn by UNSC personnel appears virtually identical to the universal BDUs worn by the [[UNSC Army Battle Dress Uniform|UNSC Army]] and [[UNSC Marine Corps Battle Dress Uniform|Marine Corps]], but features a fully enclosed helmet and is fully sealed against vacuum. These suits were used by the [[YSS-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 use vacuum suits.<ref>'''[[Halo: Reach]]''', campaign level, ''[[Long Night of Solace (level)|Long Night of Solace]]''</ref>

=== Black body suit ===
{{Main|Black body suit}}
This body suit 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 [[Heads-Up Display|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|MJOLNIR Armor]].

=== SPI Armor ===
The [[Semi-Powered Infiltration Armor]] utilized by the [[Spartan-III]]s has [[List of "seven" references in Halo|seven]] minutes of breathable atmosphere.<ref>'''[[Halo: Ghosts of Onyx]]''', ''page ??''</ref> 

=== MJOLNIR Armor ===
The [[MJOLNIR Powered Assault Armor]] system utilized by the [[SPARTAN-II Program|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]], Spartan-117 fell through the [[Earth]]’s atmosphere into the jungle of [[Kenya]], and survived, although he did use a part of the [[Forerunner Dreadnought]] as a heat shield.<ref>'''[[Halo 3]]''', campaign level, ''[[Arrival (Level)|Arrival]]''</ref><ref>'''Halo 3''', campaign level, ''[[Sierra 117 (Level)|Sierra 117]]''</ref>

=== ODST armor ===
The most common version of the [[ODST battle armor|suit of combat armor]] worn by the [[Orbital Drop Shock Trooper]]s is fully vacuum-sealed and includes oxygen reserves for 15 minutes. However, not all of the armor's variants are vacuum-protected, as some variants have leave the neck and fingers exposed.

== Covenant ==
[[Covenant Empire|The Covenant]] also use vacuum suits, 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 [[Sangheili Combat Harness|Combat Harnesses]], such as the [[Assault Harness]], [[Flight Harness]], [[Ascetic Harness |Ascetic Harness]] and [[Commando Harness]].
