In [[2552]], during the [[Fall of Reach]], the Devoted Sentries were charged with locating and recovering the numerous, powerful Forerunner artifacts scattered across the surface of [[Reach]].<ref name="WP" >[https://www.halowaypoint.com/en-us/news/canon-fodder-fighting-words '''Halo Waypoint''': ''Canon Fodder - Fighting Words'']</ref> 'Barutamee oversaw and commanded the Devoted Sentries from aboard the [[Sh'wada-pattern supercarrier|supercarrier]] ''[[Long Night of Solace]]'' during the battle.{{Ref/Reuse|universe}}

In 2552, the Fleet of Valiant Prudence, led by Supreme Commander Rho ‘Barutamee, attacked a Human planet in the [[Beta Eridani system]]. After defeating [[United Nations Space Command|UNSC]] forces, several Forerunner artifacts were uncovered. Processing them through a [[Luminary]], the fleet learnt the coordinates of another planet rich with Forerunner artifacts, and quickly moved to secure it.{{Ref/Book|Id=fb33|Halo: Fleet Battles core rulebook|Page=33}}{{Ref/Tabletop|Id=fb2|HFB|Scenario=Scenario Two: Contact}}

By [[2552#July|July 23]], the fleet had arrived at the planet, which turned out to be planet Reach, a major UNSC base. That night, the Devoted Sentries [[Battle of Visegrád|attacked]] [[Visegrád Relay]], severely disrupting UNSC communications<ref name="NA">'''Halo: Reach''', campaign level ''[[Noble Actual]]''</ref><ref name="WC" >'''Halo: Reach''', campaign level ''[[Winter Contingency]]''</ref> and attempting to find ONI data concerning the excavation of Forerunner artifacts.{{Ref/Reuse|SB}} The UNSC, believing that [[insurrection]]ists were responsible, sent Army fireteam [[3 Charlie]] to retake the relay. When 3 Charlie was all but wiped out by Covenant forces, [[SPARTAN-II program|the]] [[SPARTAN-III program|SPARTANs]] of [[NOBLE Team]] were sent to Visegrád.{{Ref/Reuse|NA}} When NOBLE reached the relay, they were ambushed by the Sentries, and a brief firefight ensued in which two Zealots were killed by [[SPARTAN-B312]] and [[Jorge-052]]. The [[Sangheili Field Marshal|Field Marshal]] who led the Sentries in the field escaped due to [[Carter-A259]] not realizing his significance.{{Ref/Reuse|WC}}

Several weeks later, one of the Sentries was present at a [[BXR Mining Corporation]] facility during the [[Battle at Szurdok Ridge]], and was killed by SPARTAN-B312.<ref name="TS">'''[[Halo: Reach]]''', campaign level ''[[Tip of the Spear]]''</ref> NOBLE would strike an even greater blow against the Sentries two days later, when [[Operation: UPPER CUT]] resulted in the death of Rho ‘Barutamee.{{Ref/Reuse|WP}}<ref name="LS">'''[[Halo: Reach]]''', campaign level ''[[Long Night of Solace (level)|Long Night of Solace]]''</ref> Despite this, the Sentries continued their mission. On [[2552#August|August 23]], the Field Marshal killed [[Catherine-B320]], the member of NOBLE who had devised UPPER CUT.<ref name="NAL">'''[[Halo: Reach]]''', campaign level ''[[New Alexandria]]''</ref>

On August 30, NOBLE recovered a fragment of the [[Smart AI]] [[Cortana]], who had been studying data from a [[Babd Catha Forerunner vessel|crashed Forerunner ship]] underneath SWORD Base. Dr. Catherine Halsey ordered NOBLE to deliver her to the {{UNSCShip|Pillar of Autumn}}.<ref name="TP">'''[[Halo: Reach]]''', campaign level ''[[The Package]]''</ref> During the [[Battle of Asźod]], just as NOBLE had completed their mission at the [[Asźod ship breaking yards]] , a {{Pattern|Ket|battlecruiser}} began moving against the ''Autumn'' while the Devoted Sentries attacked the [[Mark 2488 Onager]] providing the ''Autumn‘s'' cover. [[Emile-A239]] was quickly killed, but at the cost of two Zealots. As the Cortana fragment was transported to the ''Autumn'', SPARTAN-B312 moved to retake the Onager. After killing the Field Marshal and three Zealots, he destroyed the battlecruiser, allowing the ''Autumn'' to leave Reach with the Forerunner data.<ref name="PA">'''[[Halo: Reach]]''', campaign level ''[[The Pillar of Autumn (Halo: Reach level)|The Pillar of Autumn]]''</ref> Later that day, B312 was killed by one of the Devoted Sentries while making his final stand. However, it was too late. The failure of the Devoted Sentries to stop the ''Autumn‘s'' takeoff resulted in Humanity discovering [[Installation 04]], setting into motion a chain of events that would ultimately fracture the Covenant and cause it to collapse.<ref name="LW">'''[[Halo: Reach]]''', campaign level ''[[Lone Wolf]]''</ref>
