Between these amorphous hacker groups and the PLA’s network professionals lies a murky middle layer whose shape, not surprisingly, is indistinct, but whose mission—information warfare (IW)—is not. In 1998 the PRC launched what may have been its first experiment with a cybermilitia: a forty-person unit in a state-owned enterprise in Datong City, Shanxi Province, which had a rich talent pool drawn from some twenty universities, institutes, and companies.48 Militias are neither official government cadres nor freelance hackers. They operate in ambiguous space, connected to one or another government office by a loose string. A twitch of a government finger tightens the string, either to restrain or direct an operation. The PLA has been actively creating IW militias since about 2002, recruiting from universities, research institutes, and commercial IT companies, especially telecom firms. Some accounts call these cadres an “active reserve,” comprising eight million network operators under direct state control.
