Mjolnir Powered Assault Armor/JFO Variant

The MJOLNIR/JFO is a variant of the MJOLNIR Powered Assault Armor. It was designed and tested at Beweglichkeitsrüstungsysteme in Essen, Germany.

The JFO shoulder piece is available as an armor permutation in Halo: Reach for 1000 cR, and the helmet can be purchased for 60,000 cR. The JFO helmet appears in the armory upon reaching the rank of Warrant Officer, but is locked until Lt. Colonel.

Trivia

 * JFO stands for Joint Fires Observer, a United States military designation for troops who coordinate fire support from land-based artillery and naval gun formations, as well as close air support.
 * The visor of the JFO helmet somewhat resembles the faceplate of the armored Marvel superhero Iron Man.
