The Helghast infantry form the backbone of the Helghan war machine during the Invasion of Vekta. The troopers are trained to perform both airborne or mechanized operations, and are feared for their shock combat techniques. They often operate in squads, pinning and flanking their targets to deliver the killing blow. During the Invasion of Helghan, these soldiers are classified as Assault Infantry, even though they are essentially identical to their earlier Third Army counterparts.
Specialists are mixed in with the regular Helghast infantry. They are fairly uncommon, with only several or so appearing throughout each mission. They are identical in appearance to regular Helghast infantry, however they can be distinguished by their lighter color uniforms, which are light grey instead of dark brown.
Specialists have better quality body armor than regular infantry, and can survive about a dozen rounds from the M82 Assault Rifle before falling, compared to only 3 or 4 rounds for regular infantry. They are usually equipped with special weaponry.
Among these units, it's possible to recognize the following specialists:
Sergeant: Armed with a grenade/flare launcher pistol.
Comm Operator: Used for keeping contact with their forward CP and other squads; usually equipped with a light pistol.
Weapon Specialists: Usually equipped with heavy weapons, triple rocket launchers or light machine guns are the most common.
Every infantryman wears a dark gray fatigue uniform, designed to shield the wearer from the harsh weather conditions on Helghan, it is a multilayer carbon fiber fabric, chemically treated to protect the wearer from extreme temperatures, waterproof and difficult to burn with acid or fire and is useful protection against shrapnel and debris. Gloves and boots are made with similar materials, but are reinforced to allow the use of ropes during airborne assault. The body armor follows the same philosophy of the fatigue uniform, but is obviously made with more resistant and heavy materials, and is designed to be easy to repair on the field, using spare parts.
The armor itself is effective only against light caliber rounds and shrapnel, and provide a good shielding against acid and fire, but against anything else the infantryman must rely on cover and teamwork and support to survive. The rebreather is a standard issue for any Helghan, but the one given to military personnel is quite more advanced, and provide protection against smoke and chemical attacks, and so do the special goggles, which also shield the wearer against intense lights.
