An active-duty soldier in the U.S. Army is under investigation for his alleged leadership role in a neo-Nazi terror group, a military official has confirmed to HuffPost.

Last month, independent journalist Nate Thayer published an article identifying 22-year-old Corwyn Storm Carver as a recent leader of the Atomwaffen Division, a violent, Charles Manson-worshipping, white supremacist group whose members and supporters were implicated in five murders in 2017.

Carver is a private first class in the 1st Armored Division, stationed at Fort Bliss in El Paso, Texas.

“I can confirm that Pfc. Carver is an active-duty Soldier stationed here at Fort Bliss,” Lt. Col. Crystal Boring, a spokeswoman for the 1st Armored Division, told HuffPost in a statement. “There is an ongoing investigation into this matter, and per Army policy, additional information cannot be released until adjudication.”

The investigation will likely look into whether Carver’s alleged membership in Atomwaffen violated Army regulations regarding extremist activity and discrimination.

News of the investigation into Carver comes after two recent HuffPostreports identified 11 other members of the military who are currently being investigated for their ties to a separate white nationalist group called Identity Evropa.

The problem of white nationalists in the armed forces is severe: A Military Times poll in 2017 found that nearly 25 percent of people in the U.S. military have encountered white nationalists within its ranks.

Extremism experts and law enforcement officials have long expressed deep concern about white nationalists in the armed services, who they say pose a dangerous threat to civilian populations in the U.S. A 2008 FBI report warned that “extremist leaders seek to recruit members with military experience in order to exploit their discipline, knowledge of firearms, explosives and tactical skills as well as [in the case of active-duty military] their access to weapons and intelligence.”

Just last year, an Atomwaffen leader named Brandon Russell, who was in the Florida National Guard, was sentenced to five years in prison after law enforcement found explosive materials at his home. (They also discovered a framed photo of Oklahoma City bomber Timothy McVeigh in Russell’s bedroom.)

Having Atomwaffen members in the military is especially alarming, said Keegan Hankes, a senior research analyst at the Southern Poverty Law Center. The Atomwaffen Division, he said, is “a cell-based radical terror group” that is “advocating for violent revolution, so it’s a tremendous concern that [Carver] would get training in warfare from the U.S. government.”
