Welcome to Gaia! ::

The description for our guild should be changed to as follows:
The primary arm of the Combine occupation forces on Earth is the humanoid Combine Overwatch. Referred to by Doctor Breen as the "Trans-human arm of the sector seventeen overwatch," they are humans who have been captured, brainwashed, and modified into "trans-human" or "post-human" cybernetic creatures. They are the most frequently encountered foes faced by Gordon Freeman in his fight against the Combine.
The Overwatch system itself provides insight into the policies dictating tactics used by humanoid Combine forces. They treat whole cities as a single organism, with insurrection as an infection and their role as that of white blood cells. They frequently use terms like "contain," "sterilize," "clamp," "amputate," "parasitics," (for headcrabs) and "necrotics" (zombies). When a squad is reduced to a single trooper, he can be heard crying "Outbreak, outbreak, outbreak!"
Civil Protection personnel are humans who join the Combine of their own free will in return for privileges and basic amenities like adequate food and living accommodations and sex. Also known as CPs and Metro Cops, they are charged with keeping the local populace in line via intimidation and physical force. Interrogation, questioning, inspections, random beatings, and even outright murder are sanctioned as a means of policing their respective jurisdictions. Civil Protection personnel also patrol the canals outside city limits looking to apprehend escapees. Unlike Combine soldiers, they do not appear to be biologically enhanced, though they wear masks containing vocoders which alter the sound of their voice. The harsh, metallic character of their speech is used as a means of psychological intimidation, making their vocal utterances sound inhuman.

Combine soldiers are male humans conscripted from the general population which have undergone extensive psycho-biomechanical "enhancement." Several sources have revealed that these modifications include memory replacement and extensive surgery throughout the body to implant various mechanical devices. The cybernetic conversion procedure is performed at Nova Prospekt and the Citadel. Dr. Kleiner has described Combine soldiers as "post-human." The men with the modifications could be wounded and as a result are having the wounded parts replaced rather than recruit a new soldier due to political events on Earth.
Despite the extensive surgical modification, they nonetheless retain some semblance of humanity. When injured they grunt in pain, and can be heard shouting expletives in the heat of battle. They communicate via radio, but unlike Civil Protection officers, are not directly addressed by the Overwatch. The Overwatch announcement system can be heard 'motivating' soldiers with the possible threat of 'off-world assignment' should they fail to complete mission objectives. Such could be indicative of a small amount of independent thought if threats are used to keep the rank and file in line.
