HELLCAT-class Mjolnir

The MJOLNIR Powered Assault Armor/Hellcat is a variant of the MJOLNIR Powered Assault Armor [GEN2]. Designed using artifacts from humanity's prehistoric interstellar empire, HELLCAT closely resembles the armor worn by human soldiers during the human-Forerunner wars.

Halo 5: Guardians
Helmet: Tests with Spartan-II veterans show near-perfect synchronization with HELLCAT armor, but compatible Spartan-IV operators require an acclimatization period and tweaks to their augmentation maintenance before deployment.

Armor: Built of knowledge stolen from enigmatic ruins on a dead world and materials stripped from the vault of a shattered starship, the HELLCAT is both utterly alien and strangely familiar.
