The '''MJOLNIR Powered Assault Armor/J variant''', colloquially known as '''JFO''' or '''Joint Fires Observer''', is a variant of the [[MJOLNIR Powered Assault Armor]] manufactured by [[Beweglichkeitsrüstungsysteme]].{{Ref/Reuse|EVG}}{{Ref/Game|Id=HR|HR|Armor permutations (Halo: Reach)|Armory|Detail=JFO Helmet - Description|Quote=Beweglichrüstungsysteme was home to many projects attached to the MJOLNIR program.}}{{Ref/Book|Id=Enc11|Enc11|Page=94}}

==GEN1 overview==
===Design details===
The JFO design was engineered with the goal of allowing lone [[Spartan Operations|Spartans]] to have improved communication when deep behind enemy lines, allowing them to better conduct cross-branch artillery request communication/coordination by Spartans across the Army, Navy, and Marine Corps. Spartans fielding the JFO suit are typically deployed with regular firearms and equipment, though are usually also outfitted with the latest targeting hardware in systems such as the [[H-165 target locator]] or its [[H-295 target designator|successor]]. Target designators are [[Smart-linking|smart-linked]] to the suit's onboard technology suite, allowing the user to make quick and decisive air strikes in the field.{{Ref/Reuse|Enc11}}{{Ref/Reuse|EVG}}

The helmet is compatible with the [[UA attachments#Type O5|Type O5]] up-armour module and [[Model 990101-1 FLAMINGO]] hardened uplink.

===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===
JFO 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.
