"When we hunt, we kill!
No one is safe!
Nothing is sacred!
We are Blackwatch!
We are the last line of defense!
We will burn our own to hold the red line,
it is the last line to ever hold!"

Blackwatch Special Forces, officially designated under 1st Biological Warfare Command, is the black ops military force of the United States responsible for the containment of biohazard/viral outbreaks.They were previously deployed at Hope, Idaho to contain the viral outbreak caused by the Redlight virus, and later to New York City in order to combat the Blacklight virus.

Officially, Blackwatch does not exist - it is a black operations unit that is given free reign when it comes to containing viral outbreaks. The organization has access to vast stockpiles of military arsenal and experimental technologies, in addition to controlling the most refined information control technologies, vital to preserving the ignorance of the American public. However, following the initial Manhattan outbreak, they became publicly known, though the extent of their unethical operations remains a well-kept secret.

Furthermore, they have full authority over American military forces and local police when it comes to biological warfare - they can request any information and any amount of military forces to serve under their command, as exemplified by their use of Marines on Manhattan Island.
Each member of the organization is single-mindedly dedicated to its goal and fully believes that it justifies the means, no matter how distasteful they are. As such, Blackwatch soldiers will execute infected humans without hesitation, use area of effect weapons in urban areas and deploy heavy armor and gunships in crowded areas just to destroy a single Runner.

They will also not hesitate to firebomb city blocks just to suppress the infection, regardless of other military and civilian presence. Some members have even been noted as possessing a cruel and sadistic glee while doing so. This approach earns them the ire of any jointly deployed military forces, who usually consider them gung-ho, barbarians, bloodthirsty psychopaths, and even Nazis.

In the year following the initial outbreak in Manhattan and during the second outbreak, Blackwatch has descended into even further amoral actions and methods, performing such activities as kidnapping innocent civilians for Gentek's experiments, many of which consisted of simply locking them in rooms with particularly vicious forms of Infected and watching them get torn apart. Additionally, Blackwatch showed clear disregard for the lives of regular military personnel once more, frequently sending United States Marines on downright suicidal missions in the form of pointless patrols.
