The '''focus turret''' {{ZClass|510|Directed Energy Focus Weapon|DEFW}}{{Ref/Reuse|h4evg}} is a [[Forerunner]] [[directed energy weapon]] emplacement manufactured in the [[Ferrarius Assembler Vats]].{{Ref/Reuse|enc22}}

==Overview==

===Design details===

The Z-510 focus turret is a defensive weapon emplacement deployed at key strategic points in order to provide defensive and suppressive lines of fire.{{Ref/Reuse|enc22}} They are capable of being instantaneously phased to a location by [[Promethean Watcher|Watchers]], then held up by an anti-gravity mooring upon deployment and controlled by a beam sustainment governor.{{Ref/Reuse|h4evg}} Powered by a vacuum energy plate to gather power,{{Ref/Reuse|enc22}} the focus turret splays its upper and lower charging arms when it prepares to fire,{{Ref/Reuse|h4evg}} as it gathers energy into its ionization core located in its center.{{Ref/Reuse|enc22}} Bright rings then form around its muzzle, and it fires a charged particle beam—much like the [[Sentinel beam]]{{Ref/Reuse|h4evg}}—of ionized particles at its target.{{Ref/Reuse|enc22}} When destroyed, the focus turret disintegrate in a manner resembling that of [[Promethean Knight]]s.{{Ref/Game|Id=h4|H4|gameplay}}

The [[Covenant]] attempted to reverse-engineer the focus turret's technology using comparatively primitive electromagnetically guided plasma with weapons like the {{Pattern|M'tara|focus rifle}}.{{Ref/Reuse|h4evg}} Given it (and the focus rifle's) name, this is presumably the basis for the Covenant's [[focus cannon]] weaponry.

==Operational history==

During the [[Battle of Draetheus V]], [[Merg Vol]] was able to activate the turrets around the control room for [[X50]]'s primary weapon after having spent considerable resources to unlock its secrets. The turrets aided Vol in battle against [[Spartan-IV|Spartan]] [[Sarah Palmer]] alongside [[Merg Vol's Covenant|his forces]]. However, Merg Vol was ultimately defeated and killed by Palmer.{{Ref/Level|HSA|Mission 25: Battle for the Moon}} When accessing the [[Cistern]], Palmer encountered focus turrets guarding two of the three power cores she had to destroy in order to unlock the main door.{{Ref/Level|HSA|Mission 29: Infiltration of the Cistern}} Several more protected the area of the Cistern where Spartan [[Edward Davis]]' remains were being held in a [[Durance]], particularly the power cores Palmer had to destroy in order for a Pelican to extract the Durance.{{Ref/Level|HSA|Mission 30: The Source}}

In July [[2557]], [[John-117]], and later the crew of the {{UNSCShip|Infinity}}, faced several such turrets inside the [[shield world]] [[Requiem]].{{Ref/Level|H4|Infinity (Halo 4 level)|Infinity}} Later, a number of these turrets were hacked by [[Cortana]] on the ''[[Mantle's Approach]]'' during the Didact's [[New Phoenix Incident|attack on Earth]], during which time they took on a blue light, like those of the [[Aggressor Sentinel|Sentinels]] on Requiem, as opposed to the characteristic orange coloration of those under the [[Ur-Didact|Didact]]'s control. The turrets temporarily repelled waves of [[Promethean Crawler|Crawlers]] to help John-117 on his way to destroy the [[Composer]].{{Ref/Level|H4|Midnight}}

In that same month, many focus turrets were used against UNSC forces during the [[Battle of Installation 03]].{{Ref/Level|HSS|Mission 20: Serve and Protect}}{{Ref/Level|HSS|Mission 23: The Lion's Den}}

When the ''Infinity'' returned to Requiem in [[2558]], several focus turrets were again used against UNSC forces. [[Fireteam Crimson]] faced numerous turrets during their missions. At some point, the [[SPARTAN-IV Program|Spartan-IVs]] were able to turn the turrets of the location "[[Control]]" into allies to help repel members of [[Jul 'Mdama]]'s [[Jul 'Mdama's Covenant|Covenant]].{{Ref/SpOps|Episode=Expendable|Level=Glassman}} Later, when the Spartans searched for [[Catherine Halsey|Dr. Halsey]]'s signal at [[Cyclone]], the [[Librarian]] provided them support with some allied focus turrets along with Aggressor Sentinels.{{Ref/SpOps|Episode=Key|Level=The Search for Halsey}}

After [[Cortana]] took over the Promethean forces, focus turrets took on a modified design. Larger anti-vehicle turrets were encountered on [[Meridian]] by [[Fireteam Osiris]], being more heavily armed but rarer overall.{{Ref/Level|H5|Glassed}} The [[Warden Eternal]] would also use focus turrets as support in his engagements against Osiris and [[Blue Team]] on [[Genesis]].{{Ref/Level|H5|Genesis (level)|Genesis}}{{Ref/Level|H5|The Breaking}} Later, Osiris encountered more focus turrets in their mission to free Blue Team from Cortana.{{Ref/Level|H5|Guardians}} In [[Warzone]] simulations, like those on [[March on Stormbreak]], should the Warden Eternal be encountered as a Mythic boss, he may also spawn focus turrets against the two Spartan teams who are competing against each other for victory in the simulation.
