The Syrian Democratic Forces (SDF) is a Kurdish-led coalition of U.S.-backed left-wing ethnic militias and rebel groups, and serves as the official military wing of the Autonomous Administration of North and East Syria. The SDF is allied to and supplied by the United States–led CJTF–OIR international alliance. Founded on 10 October 2015, the SDF claims that its mission is fighting to create a secular, democratic and federalized Syria. The SDF is opposed by Turkey who view the group as an extension of the Kurdistan Workers' Party (PKK), which it has designated a terrorist group.
