Editing Hua Yuan Exterminators (section)

====Infantry Companies====
These companies form the backbone of any Exterminator regiment, no matter how specialized. Every infantryman in an Exterminator unit is considered the best of what the Hive has to offer, but even in the Exterminators the infantry are considered the best of the best.  These guardsmen are highly mobile, the physical fitness standards required to remain in an Exterminator regiment after conscription are one of the leading causes of Guardsmen washing out and being transferred to a Line Infantry unit, or in more severe cases Penal units, if not executed outright.

A standard Infantry Company is composed of at least five platoons, with typically no more than ten. These platoons will fall under the supervision of a Chief Sergeant that monitors and coordinates the squads within their platoon. The platoon sergeants then report to the company commander, typically a Captain, the Major Chief Sergeant, and the attached Commissar. The Major Chief Sergeant and the Captain manage their company, coordinate with other supporting companies, and report to the command or HQ element. However the role of the Commissar is to dispense judicial punishment amongst the ranks, and maintain good order and discipline when the platoon sergeants fail to do so, which usually occurs when a Guardsman succumbs to Xenon, or Nid-Dust and is deemed unfit for service. 

At the squad level a squad, or fireteam in a combat environment, revolves around the squad leader, typically a Staff Sergeant but no lower than a Sergeant (unless they die, in which case the highest ranking member of the squad will assume the position; this is typically the easiest way to receive a promotion). A squad usually has around six or seven Guardsmen, within the squad will be a variety a specialists, who train their battle buddies in their particular skill set should they die in the field so as not to cripple the team upon their death. Standard specialists within the squad consist of the medic, Voxman, designated breacher and point-man (the guardsman that performs the entrance breach in a Flash and Clear, and the first guardsman into the breached area; in more cramped situations a single guardsman can perform both roles), and the Hunter, or Xenon-boy. The hunter performs a crucial role in the squad, simultaneously a great honor and a great mark of shame upon the squad. The hunter is the designated Xenon user. While almost all Exterminators have used the malicious drug at least once, the hunter is the member of the squad that has used the drug the longest, and has thus built up a certain resistance to the most debilitating of its ill effects, but has likewise developed a crippling addiction to the vile substance. Hunters often spiral into insanity with prolonged use, viewing their squad mates with suspicion and eventually with violent fear, battle brothers slowly becoming Genestealer infiltrators in their clouded minds. Nevertheless, these Guardsmen play a vital role in routing out Genestealer infestations and preventing ambushes from stealthier bioforms, Exterminators bounding after their Xenon-boys like hunters after bloodhounds.
