The Atomwaffen Division (AWD) was a neo-Nazi terrorist group formed in the United States by members of the Iron March forum in 2013. Eventually, the group was found to have Canadian members and ran at least one training camp in Québec.

AWD, like other Iron March network groups, promoted the domestic terror methods detailed in Siege as a means of achieving national socialism, an approach that included advocating for widespread violence, including the endorsement of murder and sometimes rape. Before disbanding in 2020, AWD members were responsible for several murders, including the parents of one member’s partner, two of their own members, and Jewish student Blaze Bernstein. The AWD remains highly regarded in accelerationist neo-Nazi movements for the notoriety of the murders members committed and for the group’s propaganda.

Despite attempts by those influenced by the Atomwaffen to resurrect it, the Atomwaffen division is not known to operate today under its original name. However, original AWD members have started similar groups under different names and continued to operate overlapping organizations since the AWD’s official disbandment.
