Sentinel: Difference between revisions

[[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>

*'''[[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.

*'''[[Assembler Sentinel]]''' - Assemblers are presumably used to build and maintain Forerunner installations and technology, like the similarly named Constructors. Though they are not designed for combat, they will suspend their primary duties and engage Flood forms in the event of an outbreak.{{Ref/Reuse|p167}}

*'''[[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}}

*'''[[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>

*'''[[Council sentinel|Council]]''' - A special variant of Sentinel was used aboard the Forerunner [[Capital]] for security purposes. They possessed black armor, matching the black-and-red armor of [[Ecumene Council]] security personnel.<ref>'''Halo: Cryptum''', ''page 294''</ref>

*'''[[Enforcer]]''' - The Enforcers are equipped with a variety of offensive and defensive measures, including [[pulse beam]]s, [[Forerunner missile launcher|missiles]], a last-resort [[Sentinel beam]], and three frontal [[energy shielding|energy shield]]s.{{Ref/Reuse|p167}} They are designed to handle major Flood outbreaks, but are also capable of defending their Installation from other external threats.
