RKD Group was a think-tank on Earth.[1]


Human-Covenant War[edit]

The group designed and developed Project HAYABUSA, a powered combat armor similar in many ways to the MJOLNIR Powered Assault Armor, though with many differences. In late 2536, they presented to the UNSC Ordnance Commission their answer to the self-contained powered armor problem by showing HAYABUSA.[1]


After the Human-Covenant War, RKD developed the Mirmillion and Legionnaire variants of the MJOLNIR [GEN2] armor.[2] They offered the LEGIONNAIRE armor for licencing to smaller companies wishing to enter the competitive realm of powered armor manufacturing.[3]



Armor attachments[edit]


  • Since RKD group's Hayabusa Armor is based on that of Ryu Hayabusa of the Ninja Gaiden series of video games, it is possible that RKD is an abbreviation of "Ninja Ryukenden", the original name of that series.
  • Post-war, the RKD group tends to name their armors after rank of the Roman Legion and classes of gladiators.
