[[Installation 09]] heightened the security protocol and immediately launched a [[Retriever Sentinel]] to cleanse the humans and the Banished present on the rings as soon as it left Installation 00. Professor Anders successfully hijacked the local network through the control tower to temporarily take control of Retriever Sentinel to disable barriers around the control room.<ref>'''[[Halo Wars 2]]''', Campaign level ''[[The Halo]]''</ref>

==Types==

*'''[[Aggressor Sentinel]]''' - The Aggressor is the most common form of Sentinel, designed for the protection of Forerunner constructs and the small-scale suppression of Flood forms.{{Ref/Reuse|p167}} There are many forms of Aggressor, though most follow the same basic layout. In the event of a severe threat, an advanced version of the Aggressor would be dispatched to assist the more common Aggressors.

*'''[[Constructor]]''' - The Constructors are specialized Sentinels, designed solely for the construction and servicing of Forerunner structures. Like Assemblers, they are not designed for combat, but they will engage the Flood if necessary.{{Ref/Reuse|p167}}

</gallery>

*'''[[Controller]]''' - These sentinels were typically used to defend valuable technology on Installation 00. Their typical weaponry is a supercharged [[sentinel pulse]] as their main weapon, with a [[Sentinel beam]] to cover their blind spot. For defensive purposes, they can create an energy shield on their forward side. This shield is significantly stronger than that of the [[Enforcer]].<ref>'''Halo Wars 2'''</ref>

*'''[[Promethean Watcher]]''' - The Watcher is a Sentinel variant used by [[Promethean Knight]]s for combat support. They can heal and augment their damaged allies and return incoming ordnance such as grenades using a gravity-displacement beam.<ref>[http://halo.xbox.com/halo4#!an-epic-universe/characters/8c164b48-05e7-4c13-a268-f60ec3a72938 '''Halo 4 Official Site''': ''CHARACTERS'']</ref>

Those used in military applications were often classified as weapon-ships, capable of being fitted with naval-scale ordnance and defensive systems."</ref> are massive [[terraforming]] machines, used to gather raw materials for large-scale Forerunner [[astroengineering]] projects such as the [[Halo Array]].{{Ref/Reuse|p167}}

*'''[[Onyx Sentinel]]''' - Onyx Sentinels both guard and make up the artificial planet of [[Onyx]]. They use a much more powerful individual energy beam than the Aggressor, and have the ability to combine and transform themselves in order to complete a specific task. Onyx Sentinels are far more formidable opponents than more widely-used "standard" variants.

*'''[[Safeguard Sentinel]]''' - Fitted with powerful sterilization beams, the Safeguard Sentinels are highly efficient at containing and cauterizing intrusions into their assigned protectorate.<ref>[https://www.halowaypoint.com/en-us/news/bounty-hunters '''Halo Waypoint''' - ''Canon Fodder: Bounty Hunters'']</ref>

*'''[[Super Sentinel]]''' - Considerably larger than Aggressors, Super Sentinels fill the same role as the [[Enforcer]]s - combating large-scale Flood outbreaks.
