The National Socialist Movement (NSM) is a longstanding neo-Nazi group currently headquartered in Detroit, Michigan. Following the collapse of the rival neo-Nazi National Alliance in the early 2000s, the NSM by default became the largest neo-Nazi group in the United States, though it only has a few hundred active members. The NSM logo consists of a shield divided into four sections. Two sections have elements of the American flag, while the other two sections are red and black, the colors of the Nazi flag. In the center is a swastika, over which are the letters NSM. A slightly different version of this symbol also makes up the flag of the NSM.
