(→Gameplay: Shield recharge speed from Halo 3 was not the 4.25/1.75 seconds as previously written, current map files for campaign and multiplayer show the values of 5/2 seconds respectively for stun time and recharge time.) |

[[Human]]s have used energy shield technology for a relatively brief amount of time. The earliest known example is the "[[Bubble Shield|bubble shield]]", a protective device developed and deployed by the [[Office of Naval Intelligence]]'s [[Beta-5 Division]],<ref name="Manual">'''Halo: Reach''' manual</ref> which has been in service since at least [[2544]].<ref name="Package">'''Halo: Legends:''' ''The Package''</ref> The Beta-5 Division also utilizes the "[[drop shield]]", a similar device which, despite being less resilient than the bubble shield, is capable of regenerating organic tissue through unknown means. | [[Human]]s have used energy shield technology for a relatively brief amount of time.

Near the end of the [[Human-Covenant War]], ONI scientists successfully reverse-engineered the technology used in [[Kig-yar point defense gauntlet]]s, leading to the technology's incorporation into the [[MJOLNIR Powered Assault Armor/Mark V|Mark V MJOLNIR Powered Assault Armor]] and all later iterations of the series. Energy shielding technology had previously been tested with the [[MJOLNIR Powered Assault Armor/Mark IV(G)|Grenadier variant]] of the [[MJOLNIR Powered Assault Armor/Mark IV]],<ref>'''Halo: Reach''', ''The Armory''</ref> though these tests were not successful.<ref>'''[[Dr. Halsey's personal journal]]'''</ref> The UNSC also reverse-engineered an [[armor lock|"armor lock" plug-in module]] from functionally identical Covenant technology. In conjunction with the MJOLNIR armor's lock-down system, this device emits an impervious shield barrier that can deflect all small arms fire and can shed attached plasma grenades. The [[SPARTAN-III Program|SPARTAN-III]] [[Headhunters]] wear an advanced version of the standard-issue [[Semi-Powered Infiltration armor]] which features energy shields that are similar to those of MJOLNIR, though the shields share power with the suit's [[active camouflage]] module.<ref>'''Halo: Evolutions - Essential Tales of the Halo Universe''', ''Headhunters''</ref> | Near the end of the [[Human-Covenant War]], ONI scientists successfully reverse-engineered the technology used in [[Kig-yar point defense gauntlet]]s, leading to the technology's incorporation into the [[MJOLNIR Powered Assault Armor/Mark V|Mark V MJOLNIR Powered Assault Armor]] and all later iterations of the series.

While projectile weaponry is generally ineffective against Covenant starship shielding, [[directed energy weapon]]ry can disable shields with relative ease, in much the same manner as Sangheili energy shields. Another way to disable the shipboard energy shields is through the use of a large-scale electromagnetic pulse.<ref>'''[[Halo: The Fall of Reach]]''', page 153</ref> | While projectile weaponry is generally ineffective against Covenant starship shielding, [[directed energy weapon]]ry can disable shields with relative ease, in much the same manner as Sangheili energy shields.

The Covenant also use energy shields as [[hangar bay]] doors. These devices prevent the evacuation of atmosphere from the hangar bay and deny unwanted entry and exit. They can be phased in such a manner that atmosphere remains in the hangar bay while single ships can enter the vessel. | The Covenant also use energy shields as [[hangar bay]] doors.

The Covenant make extensive use of stationary energy shield devices. One of the most common is the energy barrier, which is used to cordon off restricted areas and to deny enemy movement within invaded cities.<ref>'''Halo 3: ODST''', campaign levels ''[[Mombasa Streets]]'', ''[[Tayari Plaza]]'', and''[[Kizingo Boulevard]]''</ref> This technology can also be used to form [[anti-vehicle barrier]]s; though vehicles and projectiles are repelled by these barriers, human and Covenant soldiers can pass through them on foot.<ref>'''Halo 3''', campaign level ''[[Tsavo Highway]]''</ref><ref>'''Halo Wars''', campaign level ''[[Relic Approach]]''</ref> [[Stationary shield generator|Smaller-scale barriers]], including [[Deployable Cover|man-portable ones]], are often used to provide cover during firefights. | The Covenant make extensive use of stationary energy shield devices.

Some lighter versions have only frontal shielding, while [[Shade#Anti-air Shade|anti-aircraft models]] have multi-directional shielding. | Some [[Shade]] turrets are equipped with energy shielding.
