US Military Struggles to Weed Out Members With Far-Right Ties Agence France-Presse WASHINGTON - The arrest of a U.S. soldier with far-right sympathies who is suspected of plotting an attack on American soil to spark "chaos" has highlighted a challenge for the Pentagon: purging its ranks of extremists. Jarrett Smith, a private in the U.S. Army based at Fort Riley in Kansas, was arrested and charged in federal court with one count of distributing information related to explosives after offering a detailed explanation to an undercover FBI agent. Smith also expressed interest in targeting members of the leftist group Antifa and heading to Ukraine to fight with a far-right paramilitary group, the FBI says. But he is hardly the first U.S. soldier to reveal far-right or ultra-nationalist leanings -- and some fear the U.S. military is being used as a training ground by extremist groups. .
