'''PIONEER-class Mjolnir''' is a variant of the [[MJOLNIR Powered Assault Armor (GEN2)|MJOLNIR Powered Assault Armor [GEN2]]] manufactured by [[Acheron Security]].{{Ref/Game|Id=H4|H4|Armor permutations (Halo 4)|Spartan Armor Customization|Detail=PIONEER Description}}

==Overview==
===Design details===
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/Game|Id=H5|H5G|Armor permutations (Halo 5: Guardians)|Armor Permutations|Detail=PIONEER - Helmet Description|Quote=The sensor fidelity and high-bandwidth storage capacity in the PIONEER helmet makes it ideal for detailed environment scans used in War Games and intelligence analysis scene reconstructions.}} The helmet also has a dual-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/Reuse|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/Reuse|H4EVG}}

It is intended primarily for reconnaissance operations in unknown or hostile environments,{{Ref/Reuse|h4guide}} and was constructed to endure the rigors of a potentially hostile, alien environment, and to optimize overall performance through inhibitor mitigation.{{Ref/Site|Id=h4guide|URL=http://www.halowaypoint.com/en-us/intel/inteldetail/47d93a8b-6d8f-4f4b-8d98-e3b6d10d8192/pioneer|Site=Halo Waypoint|Page=Halo 4 Interactive Guide - Armor Types: Pioneer|D=23|M=4|Y=2013|LocalArchive=Halo 4 Interactive Guide#Armor Types}} It also pairs advanced environmental sensors with Acheron's latest threat detection systems.{{Ref/Reuse|H5}} The early prototype of the suit{{Ref/Site|Id=CFAO|D=01|M=6|Y=2020|URL=https://www.halowaypoint.com/en-us/news/armor-online|Site=Halo Waypoint|Page=Canon Fodder - Armor Online}} later recieved additional testing and upgrades at [[ANVIL Station]] following its initial usage on Installation 03.{{Ref/Game|Id=H3MCCDesc|MCC|''[[Halo 3]]'' [[Armor customization (Halo 3)|customisation]] menu}} The suit went into a full production run following its ANVIL testing.{{Ref/Reuse|CFAO}}

===Usage===
Pioneer-class armor is equipped by [[Spartan]]s providing protection to [[ONI]] expeditionary groups.{{Ref/Reuse|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/Reuse|H4EVG}}{{Ref/Reuse|H4}} 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/Reuse|H4EVG}} Pioneer suits have also been used to protect science teams on colonies and even to protect planetary engineering rigs.{{Ref/Reuse|H4EVG}}
