ARGONAUT-class Mjolnir

ARGONAUT-class Mjolnir is a variant of the MJOLNIR [GEN2] armor.

Development history
Once the helmet clears the UNSC Ordnance Committee's approval loops, this armor will be able to accept next-generation Block 10 Interface Controller hardware.

Usage
Rarely seen outside of ONI, ARGONAUT users must undergo an extensive synchronization process to "train" the suit's move-by-wire reflex enhancers.

Halo 5: Guardians
Argonaut was first introduced as an armor set in Halo 5: Guardians. The suit is not a fully-original design, and employs several Halo 4 armor pieces including the EVA shoulders, Ricochet forearms and Recruit legs. The Argonaut set has two alternate skin designs; Idmon and Nestor.

Trivia

 * The armor is named after the Argonauts, a band of heroes and sailors aboard the Argo in Greek mythology.
 * The armor's skins are named after Idmon, an Argonaut seer, and Nestor, an Argonaut and the King of Pylos.
