Project SLEIPNIR

Project SLEIPNIR is a cutting-edge program administrated by the United Nations Space Command. It concerns the creation and use of unique combat dropships tailored specifically for use by Spartans. FOEHAMMER-class Mjolnir is a forward-looking Mjolnir design being evaluated for use with the project. The armor's helmet features an ultra-wideband vehicle cyberlink which induces total body paralysis to allow for better pilot synchronization.

Trivia
In Norse mythology, Sleipnir is the eight-legged horse of  Odin.
