An '''anti-vehicle barrier''' is a wall of plasma energy used to stop [[:category:Vehicles|vehicles]] and [[:Category:Weapons|weapons]]. The [[Covenant Empire|Covenant]] barrier can be easily penetrated by other objects, including enemy infantry.

== Background ==
The barrier functions similarly to a large [[shield door]], and bears a resemblance to the [[Deployable Cover]] [[equipment]]. It was first seen in use during the [[Harvest campaign]],<ref>'''[[Halo Wars]]''', campaign level, ''[[Relic Approach]]''</ref> and several variants later used in [[2552]] during the [[Battle of Mombasa]] and on the [[Tsavo highway (location)|Tsavo Highway]] to prevent [[United Nations Space Command|UNSC]] forces from reaching [[Voi]].<ref name="tsavo">'''[[Halo 3]]''', campaign level, ''[[Tsavo Highway]]''</ref> The barriers seen in Mombasa were apparently a more advanced iteration of the technology, featuring a fully protected power source and not allowing enemy infantry to pass through.<ref>'''[[Halo 3: ODST]]''', campaign level, ''[[Mombasa Streets]]''</ref> The power sources of the barriers are sometimes protected by additional sets of [[roadblock]]s.{{Ref/Reuse|tsavo}}

In [[2558#October|October 2558]], during the [[Battle of Nuusra]], [[Jul 'Mdama's Covenant]] deployed two of these barriers to block access through old ruins. Unlike the barriers encountered in [[Voi]] and on [[Harvest]], infantry forces could not pass through these to reach the power source. [[Fireteam Osiris]] was able to take down the first one by heading through a side passage in a nearby, where a small opening gave them a shot on the shield generator. In the second case, Osiris was able to break through a cracked wall below the shield's location and come up behind it to take out the shield generator.<ref>'''[[Halo 5: Guardians]]''', campaign level ''[[Enemy Lines]]''</ref>

On [[Genesis]], the Covenant deployed several of these to protect one of the gravitational cores Osiris had to destroy to free [[Blue Team]]'s [[Cryptum]]. Unlike the other barriers, these were vulnerable to weapons fire, particularly from a [[HRUNTING/YGGDRASIL Mark IX Mantis|Mantis]], taking down the shields and allowing Osiris to destroy the gravitational core and continue on with their mission.<ref>'''[[Halo 5: Guardians]]''', campaign level ''[[Guardians]]''</ref>

==Trivia==
*It is only effective in halting vehicles and projectiles; a soldier on foot can traverse it harmlessly.
*It can be taken down by explosions near the shield generator on the side opposite the generator.
*In ''[[Halo 3]]'', the shield barrier can sometimes be destroyed from the outside by explosives. The shield is not scripted to block the splash damage of explosives, therefore the generator is vulnerable. This can be especially helpful on higher difficulties, as the player can destroy the shield from a distance without having to engage multiple [[Jiralhanae|Brutes]] in close quarters. It may also be destroyed by ramming the generation point hard enough with a vehicle; it is possible that minor splash damage occurs upon the crash, thus destroying the barrier.
