'''PIONEER-class Mjolnir''' is a variant of the [[MJOLNIR Powered Assault Armor (GEN2)|MJOLNIR Powered Assault Armor [GEN2]]] manufactured by [[Acheron Security]].<ref name="Halo 4">'''[[Halo 4]]''' ''- Armory description''</ref> 

==Overview==
===Specifications===
The PIONEER helmet features passive, redundant environmental scanners whose the sensor fidelity and high-bandwidth storage capacity make it ideal for detailed environment scans used in [[War Games]] and intelligence analysis scene reconstructions.<ref name="H5 Armory">'''[[Halo 5: Guardians]]''' ''- Armory description''</ref> The helmet also has a duel-locked rebreather (YV-65) leveraged in hostile environments. It also features a twin-plated visual sensor for increased range of spectrum. The suit also has PNR-S7 split-convex pauldrons.<ref name="H4EVG"/>

===Development history===
As a result of the [[UEG]]'s pioneer initiative in order to claim new territories for colonization, [[Acheron Security]] set aside a budget and design team specifically for such endeavors, and within months Pioneer was presented. The suit was eventually put into full production and tested at the [[Acheron Trauma Sim]].<ref name="H4EVG"/>

It is intended primarily for reconnaissance operations in unknown or hostile environments,<ref name="h4guide"/> and was constructed to endure the rigors of a potentially hostile, alien environment, and to optimize overall performance through inhibitor mitigation.<ref name="h4guide">[[Halo 4 Interactive Guide#Armor Types|'''Halo 4 Interactive Guide''' ''- Armor Types: Pioneer'']]</ref> It also pairs advanced environmental sensors with Acheron's latest threat detection systems.<ref name="H5 Armory"/>

===Usage===
Pioneer-class armor is equipped by [[Spartan]]s providing protection to [[ONI]] expeditionary groups.<ref name="h4guide"/> 

The armor's first, and most notable, usage was during the first highly-classified exploration efforts of [[Installation 03]] by [[Ivanoff Station]]'s research deployments.<ref name="H4EVG"/><ref name="Halo 4"/> Since then the Pioneer variant has been used in assisting in the security and protection of over two dozen field teams and science detachments.<ref name="H4EVG"/> Pioneer suits have also been used to protect science teams on colonies and even to protect planetary engineering rigs.<ref name="H4EVG"/>
