The Communist Combat Formations (FCC) were a far-left armed organization in Italy that operated from 1977 to 1978 during the "Years of Lead". It was founded by Corrado Alunni in June 1977 after his departure from the Red Brigades, and the group occasionally cooperated with Prima Linea. In 1978, the FCC merged with Prima Linea to form the Armed Proletarian Squads.
