MJOLNIR Armor

The MJOLNIR Powered Assault Armor is a breed of fiercely padded and armored exoskeletons made specifically for Spartans, super-powered soldiers of the UNSC from the Halo games. It is most famously used by John-117, also known as Master Chief, as he dons a suit of olive MJOLNIR armor throughout all four games.

Features
The armor is nearly indestructible, as it is made out of heavy titanium alloy plating to deflect any shot ammunition or dampen any explosions. It is also heat resident, allows the user to roam in the vacuum of space and has a visor that displays a HUD (Heads-Up-Display), which has a motion tracking radar. The alloys contain recharging over-shields to even further the suit's protection and weighs 1,000 pounds in all.

Despite this, a Spartan's enhanced physical condition allows them to jump much higher than a normal human even with the suit's large mass. The MJOLNIR's reactive circuits are linked up to Spartan's brain so they don't execute moves to quickly or too slowly, and forces them to plan a head so they don't make any mistakes on the battlefield.

Trivia

 * MJOLNIR is named after Mjolnir, a large hammer wielded by Thor from Norse mythology.
