(It's hardly an inexcusable retcon (much less so than the design overhaul of the Dawn), given how they were already established on Anchor 9.) |

'''Energy barriers''', sometimes referred to as '''energy fields''', are a type of visible energy field used to separate a pressurized environment from the vacuum of space.<ref>'''[[Halo: Contact Harvest]]''', ''page 98''</ref><ref>'''Halo: Contact Harvest''', ''page 309''</ref> Energy barriers are useful because they allow solid matter through, but not gases, such as [[oxygen]] and neon. However, before matter passes through, the pressure on both sides must be equalized, to minimize the risk of explosive decompression. | '''Energy barriers''', sometimes referred to as '''energy fields''', are a type of visible energy field used to separate a pressurized environment from the vacuum of space.<ref>'''[[Halo: Contact Harvest]]''', ''page 98''</ref><ref>'''Halo: Contact Harvest''', ''page 309''</ref> Energy barriers are useful because they allow solid matter through, but not gases, such as [[oxygen]] and neon.

The Covenant use energy barriers as hangar doors, in [[airlock]]s and for [[boarding|boarding parties]] to board enemy ships. Energy barriers are present on [[Covenant boarding craft]], on the end of the craft's penetration tip.<ref>'''[[Halo 2]]''', level ''[[Cairo Station (level)|Cairo Station]]''</ref> Energy barriers are also used as exterior doors in [[hangar bay]]s on Covenant starships.<ref>'''[[Halo: Combat Evolved]]''', campaign level, ''[[The Truth and Reconciliation]]''</ref> The barriers can also be configured to block all vehicles or personnel or allow them to pass through when required.<ref>'''[[Halo: Reach]]''', campaign level, ''[[Long Night of Solace (level)|Long Night of Solace]]''</ref> | The Covenant use energy barriers as hangar doors, in [[airlock]]s and for [[boarding|boarding parties]] to board enemy ships.

By [[2552]], | By [[2552]], the UNSC had also begun to employ energy barrier technology in their space installations and ships in a fashion similar to the Covenant. Examples of human energy barriers include the [[UNSC Sabre engineering facility|Sabre engineering facility]] on the [[Refit station|orbital dockyard]] ''[[Anchor 9]]'',<ref>'''[[Halo: Reach]]''', multiplayer map, ''[[Anchor 9 (level)|Anchor 9]]''</ref> and the windows of the {{Class|Charon|light frigate}} {{UNSCShip|Forward Unto Dawn}}.<ref>'''[[Halo 4]]''', campaign level ''[[Dawn (level)|Dawn]]''</ref> As the most advanced warship in the [[UNSC Navy|Fleet]], the hangar bays of the {{UNSCShip|Infinity}} are also equipped with energy barriers.<ref>'''[[Spartan Ops]]''': [[S1/Exodus|S1E10 ''Exodus'']]</ref> | ||
