Jordan Duncan, 29, pleaded guilty in North Carolina in June to aiding in the manufacture of a firearm.
Duncan and four other men, including two other ex-Marines, were arrested in 2020 in connection with what authorities described as a neo-Nazi plot to sow chaos by targeting the power grid.
« We have now brought to justice all five of the defendants involved in a self-described ‘modern day SS,’ who conspired, prepared, and trained to attack America’s power grid in the name of violent white supremacist ideology, » Attorney General Merrick Garland said in a statement.
FBI Director Christopher Wray said the group was « inspired by racially motivated violent extremism. »
« If the defendants had been able to carry out an attack it could have caused suffering to thousands of American citizens, » Wray said.
The other four defendants were previously sentenced to prison terms between 21 months and 10 years.
According to court documents, two members of the group were active on « Iron March, » a neo-Nazi online forum, until it was closed in 2017. They also recruited the other three people involved.
The group accumulated firearms and produced a video of live-fire training in the desert near Boise, Idaho, that ended with the phrase « Come home white man » as the final frame.
Components of the power grid in the northwestern United States were listed as potential targets in handwritten notes found in the possession of one of the conspirators.
