A cyber force is a military branch of a nation's armed forces that conducts military operations in cyberspace and cyberwarfare. The world's first independent cyber force was the People's Liberation Army Strategic Support Force, which was established in 2015 and also serves as China's space force. As of 2022, the world's only independent cyber forces are the PLA Strategic Support Force, the German Cyber and Information Domain Service, and the Singapore Digital and Intelligence Service.
