Anti-Dalek Force

The , often abbreviated to just ADF, was a military and scientific organisation authorised by the United Planets to find ways of defeating the Daleks. The precise time period and area of space in which they operated was unknown, but it included at least the solar system during a period where humans had colonies well beyond Earth.

Two of its primary agents were its leader, Space Major Joel Shaw and the android, Mark Seven. (DWA: Terry Nation's Dalek Annuals 1976 - 1979)
