Armiger

A group of armigers including (left to right) a Soldier, Officer and Sniper.

Armigers are a sub-classification of Sentinel designed and employed by the Forerunners for use in planetary warfare. Unlike typical Sentinel designs, primarily renowned for their use of flight, armigers are bipedal combat platforms specialising in tactical infantry engagements within enemy constructs and on planetary surfaces. Armigers were particularly heavily used by the Forerunners in their campaigns against ancient humanity and later, their genocidal war against the Flood.

Armiger units may be colloquially referred to as "Promethean Soldiers" or similar; this is in reference to their deployments alongside Warrior-Servant and Promethean forces (particularly the latter) and not as an indication that they are of a similar origin to the Composed essences of the Promethean Knights. Similarly, the Soldier is simply one variant of armiger, albeit the most common (see here for details on armiger variants). Inversely, Knights consist of Composed essences driving an armiger body.

Design details

Armigers are primarily constructed by the Ferrarius Assembler Vats, and average a total height of around 2.5 metres (8.2 ft) and weigh on average around 180 kilograms (400 lb). They are primarily constructed of an alloy composed of various metals and machine-cells. The smartmatter structure is capable of interfacing with the armiger's artificial neural framework, which allows the controlling ancilla to repair damage and change their form at will, Despite outward visual similarities, armigers are a classification of Sentinel and thus do not house a composed mind in the same matter as that of their Promethean cousins. During their earlier deployments, armiger ancillae demonstrated considerable autonomy, though later units were limited due to their vulnerability to the logic plague used by the Flood. Their chassis' are capable of housing the artificial intelligence of a Monitor; such as in the case of 343 Guilty Spark.

Due to their bipedal robotic design, they bear a similar posture and frame as a human; even down to the orientation of their plated musculature. Despite this resemblance, armigers distinctly display the design aesthetics of the Forerunners. The design of the armigers displays unconventional angles, angular apertures, and floating items of dress. Though their bodies are thin and lithe, the armigers are heavily armored across their entire body. The face of an armiger is composed of symmetrical plates—made of the same alloy as their body—and noticeable "eyes" that glow the same color as other lights found in breaches in and around their armor. Henry Lamb suspected that a rigid hard light composition holds the components of an armiger together. Armigers are quick and agile, and have the capability to easily avoid incoming weapons fire.

For locomotion, armigers use two bipedal legs powered by what Usze 'Taham likened to pistons and servomotors. They are additionally capable of using Slipspace translocation to rapidly traverse the battlefield.

They are capable of communicating, and can let out a variety of calls and sounds, such as roars, hisses, and ear-splitting death cries. A certain deafening noise used by armigers indicates the presence of hostiles nearby to other armigers in the area. The vocalization of an armiger was considered by Henry Lamb to be comparable to those of a human. Armigers later encountered by Fireteam Osiris and within UNSC War Games simulations vocalised in a synthesised voice, though were fully capable of speaking (and even taunting) in human languages.

Armaments

Armigers are armed with an assortment of weapons. Some use energy staves that have a geometrical blade of hard light at the end. These staves are capable of blocking projectile fire from weapons. Armigers also arm themselves with powerful, marksman-like energy rifles that fire hard light-like ammunition. An armiger is able to "call" any weapon into its hand by having various pieces of its arm form into the weapon itself.

In a combat situation, armigers may even extend to picking up and using the discarded weaponry of their enemies. This includes martial weaponry such as the Sangheili energy sword, or even using firearms and vehicles such as the MA5D assault rifle or M12B Warthog (among others).

Variants

A common ability for armigers is the ability to transfigure their form to repair damage or even adjust their visage for aesthetic purposes. They were employed by various factions and lobby groups within the Ecumene, with more recent UNSC training simulations manifesting some of these variations (albeit in a largely speculative framework).

The most common kind of armiger was the Soldier; a general-purpose automaton designed for engaging enemies in numbers with high speed. Sub-types of the Soldier employed in War Games simulations include;

• Hydra Soldier
• Soldier Bandit
• Soldier Commando
• Soldier Enforcer
• Soldier Guard
• Soldier Operative
• Soldier Specialist

The other major forms of armiger encountered include the Sniper and Officer.

Role and responsibilities

"I think he's saying that these Forerunner machines are defensive drones that supported Forerunner warriors. Now they guard this place."

— Doctor Luther Mann, translating for Drifts Randomly upon sighting armigers on Installation 00

Armigers were used by the Forerunners for the purposes of planetary warfare, storming enemy strongholds, and boarding and raiding enemy warships. They specialise in tactical infantry engagements, and were typically deployed in support of Forerunner warriors from Builder Security and the Warrior-Servants. During the later portions of the Forerunner-Flood War, the remaining armigers were tasked with the protection of valuable Forerunner sites.

Armigers are intelligent enough to use the environment and their surroundings to their advantage, such as knocking a giant tree down a mountain or setting a giant rockslide in motion to trample opponents.

Operational history

Prehistory

Armigers were first utilized by the Didact's Warrior-Servants during the human-Forerunner wars, from approximately 107,445 to 106,445 BCE. The constructs proved incredibly useful in boarding actions against prehistoric human warships, particularly when attempting to infiltrate the confined spaces of human vessels.
