'''Assembler Sentinels''' are a type of [[Strato-Sentinel]] employed by the [[Forerunner]]s.{{Ref/Book|Enc22|Page=335}} Like the similarly-named [[Constructor]]s, Assemblers are used to build Forerunner installations and their components.{{Ref/Book|Id=Enc22|Enc22|Page=328}}

==Overview==
===Design===
With an overall design similar to that of other [[Strato-Sentinel]]s like the [[Steward Sentinel]], the Assembler Sentinel consists of a vaguely disc-shaped, ovoid body with three central luminous ocular sensor "eyes."{{Ref/Reuse|Enc22}} Some Assembler Sentinels incorporate tower-like protrusions at the edges of its upper surface,{{Ref/Comic|Id=CoL|H3CoL}} while others do not.{{Ref/Reuse|Enc22}}{{Ref/Reuse|CoL}}{{Ref/Film|Id=Origins|HLeg|Episode=Origins}} Beneath the Assembler's large body hangs several [[gravitic]] [[grappler]] appendages. Alongside these grapplers, Assemblers also feature integrated [[energy shielding]] and warship-grade [[Directed-energy weapon|directed-energy projectors]] for defense.{{Ref/Reuse|Enc22}}

===Operation===
Assembler Sentinels are predominantly designed and employed for the construction, maintenance, fabrication, transportation, and reconditioning of large superstructures.{{Ref/Reuse|Enc22}}{{Ref/Twitter|franklez|1179076414487662592|Frank O'Connor|Quote=They are deliberate variants created by the Studio4°c in partnership with us - and they are canonical and in that sense those variants could show elsewhere. They are tweaked as new designs to infer re-seeding and general array and repopulation maintenance duties. See also Iris|D=29|M=04|Y=2022}} They typically work alongside [[Retriever Sentinel]]s, utilising the resources harvested by the Retrievers for the construction of large structures such as [[Halo Array|Halo rings]].{{Ref/Reuse|foundry}} Assemblers may also be utilised to conduct finishing work on structures emerging from large construction looms.{{Ref/Reuse|Enc22}}

Although they were not initially designed for combat, they will suspend their primary duties to engage [[Flood]] forms in the event of an outbreak.{{Ref/Reuse|Enc22}}{{Ref/Book|Id=EVG|EVG|Page=167}}

==Operational history==
During the [[Forerunner-Flood war]], Assemblers were sometimes used in an offensive role against the [[Flood]], using their gravitic [[grappler]]s against the parasite in a limited offensive capacity.{{Ref/Reuse|Enc22}} Toward the war's end, Assemblers were used to construct the [[Excession]] on [[Earth]].{{Ref/Reuse|CoL}}

The [[Foundry]] of [[Installation 00]] is populated by numerous Assemblers, as well as Retrievers. While the Retrievers extract resources and minerals from the small [[moon]] held there, the Assemblers use the materials to build components of the [[Halo Array]] and to repair the Ark, if required.{{Ref/Reuse|foundry}}{{Ref/Game|HW2|Phoenix Logs|Detail=Forerunner Sentinels}} Assemblers were used alongside [[Extractor Sentinel]]s to construct [[Installation 08]].{{Ref/Book|Enc22|Page=343}}{{Ref/Book|Enc22|Page=356}}

==Production notes==
{{Main|Guardian Forest}}
The Assembler Sentinel was originally conceived for the cut ''Halo 3'' level, [[Guardian Forest]], being simply referred to as a Strato-Sentinel. One of the main objectives for the mission was to activate The Ark's sentinel defences to destroy [[Truth's fleet]], which included some Assemblers.{{Ref/Site|Id=Stokes|URL=https://rpstokes53.wixsite.com/work-of-rob-stokes/halo-3|Site=Work of Rob Stokes|Page=Halo 3|D=14|M=10|Y=2025}}
