Aggressor Sentinel: Difference between revisions

'''Z-1500 Automated Systems Drones''' ('''Z-1500 ASD'''),<ref name="h4evg">'''[[Halo 4: The Essential Visual Guide]]''', ''page 133''</ref> more commonly known as '''Aggressor Sentinels''',<ref name="EVG">'''[[Halo: The Essential Visual Guide]]''', ''page 167''</ref> are [[Forerunner]] automatons programmed to act as security and maintenance drones, suppress small-scale [[Flood]] outbreaks, and protect Forerunner installations. As the basic type of the fairly inclusive [[Sentinel]] class, Aggressors are generally referred to simply as '''Sentinels'''.{{Ref/Reuse|EVG}}

Aggressor Sentinels have two arm-like appendages, with two fine manipulators at the end of each arm. Their central head rests above a curved undercarriage generally housing an offensive [[Sentinel beam|sterlization beam]]. Their powerful beam weapons and defensive energy shields make them very effective in combat against intruders or foreign objects that present themselves as threats. Aggressor Sentinels are also equipped with a small [[reconstitution emitter]], which uses lasers to repair damaged [[Forerunner]] constructs in conjunction with [[Constructor]]s and for self-repair should the Aggressors be damaged in combat.{{Ref/Reuse|encyclopedia}} Aggressors are propelled by both an anti-gravity unit located on the undercarriage and small, exotic form of [[impulse drive]] which enables them to travel at high speeds.{{Ref/Reuse|h4evg}} They are also capable of tapping into their installation's [[teleportation grid]].{{Ref/Reuse|h4evg}}

Aggressor Sentinels are the first automated defense systems to assist a in a given situation and generate a proper response protocol, deploying to an area of interest via [[Sentinel launcher|wall-mounted launchers]].{{Ref/Reuse|SI}}{{Ref/Reuse|HINF}} While Aggressors are strong enough to handle small-scale battles, they are more of a supplement rather than a reliable combat system. The Aggressors' weapons systems are limited and not as powerful as some of the other Forerunner weapons employed against the Flood.{{Ref/Reuse|SI}}{{Ref/Reuse|QZ}} Because of their limited ancilla, they are only individually able to handle situations on a basic scale, which makes them vulnerable to strategic Flood attacks.{{Ref/Reuse|Enc22p326}} Their limited intelligence means they are often unable to perform evasive maneuvers when facing imminent attack and are usually destroyed.{{Ref/Reuse|SI}}{{Ref/Reuse|QZ}}{{Ref/Reuse|HINF}} In overwhelming numbers, Aggressors are capable of impressive coordination and are more than capable of handling a situation for a certain time until more permanent measures can be applied.{{Ref/Reuse|Enc22p326}}
