The m/12 Integrated Combat Helmet forms a part of the Grade III armor system.
The helmet provides NBC protection, limited duration life-support, adjustable helmet size and configuration with fully adaptable suspension and padding. Also has an on-board computer and short-range radio, along with an ability to interface with its user's occipital implant and any external electronics.
The radio unit has three PTTs for the built-in radio and two connection ports for external devices on either side of the helmet. The antenna of the built-in radio is housed in the structure of the helmet, and the side prongs contain microphones.
The nano-glass visor retracts and disassembles into a reservoir when not in use, has variable exterior reflectivity and opacity, and can be used as a psychological warfare tool if needed (also known as Eyes). By default outside of combat the visor is set to reflective semi-transparent gold, while in combat it turns to outwardly opaque matte black.
The detachable face shield/life support unit comes equipped with a voice projector and air regulator, while the NBC suite and exhaust ports are housed in the prongs. The air feed port also allows connection to a separate rebreather unit or life support pack.
The main structure of the helmet is divided into four main sections: the ballistic foreplate, the sides and prongs, the back plates and the cowl.
The plate constitutes the chief protective part of the system, made from light-weight ceramics, polymers and fibers in a layered structure. The plate forms the form of the helmet with the second part of the structure: the sides.
The sides contain the active ear protection and headset, as well as the prongs. The prongs contain part of the distributed computer as well as intakes for the life support unit. These intakes either take in outside air and filter it, or air from an attached reservoir (the connecting hoses are usually secured in a sleeve on the nape of the cowl). Alongside the air conduits, there's a hydration tube on the left prong, allowing quick hydration from a pack-mounted bladder (again the tube from the external reservoir is housed in a sleeve), and a radio cable connector on the right prong (again, the cord is in a sleeve).
The back plates of the helmet extend when removing the system, allowing quick doffing of the helmet. Also when donning the system, the plates form part of the suspension and secure the helmet tightly on the combatant's head. The lower plate also holds part of the cowl and the occipital interface port.
The cowl is a fabric mesh that is secure against normal cutting actions and is self-healing in the event of structural breach. The fabric partly constricts around the user's neck when worn, but not so much as to cause discomfort. The cowl can bond with any thermal glove or soldier-enhancing nano-carbon suit to provide an air-tight seal.
The helmet can be used with or without the face plate, though the unit does not restrict user performance in situations where its use is not necessary. The outer shell is coated in an adaptable camouflage film, usually depicting the same pattern and color scheme as the worn combat suit or armor, though additional fabric helmet covers can be used.
The sides are mounted with ARC-rails for additional equipment and the front has an integrated scope mount for sighting units not built-in in the helmet.
The system is rated for 2h operation in vacuum, 24h operation in mildly caustic environments and indefinite operation in non-hostile non-terrestrial atmospheres, granted an outside air reservoir is used.
The A1 version extended the main structural plate for improved balance and having an extended and reallocated battery unit.
It was about time my troops needed something that would set them far to the future.
I'm trying to be as original as I can, but some features just have to be there.
Inspirations are pretty clear: Halo marines, Mass Effect and a few others that might be at the back of my mind...
