==GEN1 overview==
===Design details===
JFO is a Mjolnir variant that improves artillery request communication/coordination by Spartans across the Army, Navy, and Marine Corps. Spartans employing JFO are also fielded with systems and programs to protect them.{{Ref/Reuse|EVG}}

===Development history===
JFO was developed by [[Beweglichkeitsrüstungsysteme]] at the [[Special Warfare Center Essen]].{{Ref/Reuse|EVG}} It was considered an "ill-favored" entry into MJOLNIR development, but the JFO helmets were ultimately one of its most successful entries.{{Ref/Reuse|HI}} As late as [[2560]], the GEN1 JFO could still be requisitioned by [[Spartan Operations|Spartans]], upgraded to be roughly equivalent to GEN3.{{Ref/Site|Id=CFParallel|URL=https://www.halowaypoint.com/en-us/news/parallel-threads|Site=Halo Waypoint|Page=Canon Fodder - Parallel Threads|D=25|M=6|Y=2021}}

===Usage===
It was often fielded by single Spartans in reconnaissance, infiltration, and artillery targeting scenarios behind enemy lines.{{Ref/Reuse|EVG}} In [[2553]], the JFO helmet was worn by [[SPARTAN-III program|SPARTAN-III]] [[Owen-B096]] as part of his mission with [[Outpost Discovery]].{{Ref/Comic|Halo: Lone Wolf}}{{Ref/Generic|[[Halo: Outpost Discovery]]}}

==In-game information==
===''Halo: Reach'' - GEN1===
{{Quote|Designed and tested at Beweglichrüstungsysteme this helmet is fully compatible with all armor systems.}}
The JFO helmet appears in the armory upon reaching the rank of {{Rank/HR|wo|link=yes}}, but is not unlocked until {{Rank/HR|ltcol|link=yes}}.{{Ref/Reuse|HR}}

The helmet features a large visor, shaped like a shield or a fattened "T", and has two small air intakes on the cheek areas. Overall, the helmet provides significant armor coverage, protecting the majority of the head while maintaining a large field of vision.

In-game, the HUL-I is available only for the JFO helmet. The shoulder pieces are semi-circular arches that jut outwards from the shoulders. They also feature black, two-pronged protrusions that point parallel to the arm, and away from the hands.
