Combat 18 is a British neo-Nazi organization formed in 1992 with the numbers in its name corresponding to the initials of Adolf Hitler. It was created by Charlie Sargent and shares an ideological connection to Blood and Honour, a white power music network and political movement formed in 1987. Combat 18 engages in harassment and attacks targeting immigrants, left-wing individuals, and other factions. It operates through small autonomous cells and has experienced leadership changes and legal issues but continues neo-Nazi activities in the UK today.
