A soldier stationed at Fort Riley has been charged with sending bomb making instructions over social media.   Jarrett William Smith, 24, is charged with one count of distributing information related to explosives and weapons of mass destruction.

Smith was transferred to Fort Riley in July.  According to an FBI affidavit, Smith said on Facebook he was interested in traveling to Ukraine to fight with a paramilitary group the Azov Batallion. 

During a chat,  Smith offered to teach other Facebook users to make cell phone explosive devices "in the style of Afghans".  The affidavit said Smith told investigators he was looking for "radicals" like himself.  He reportedly talked about killing members of Antifa and destroying nearby cell towers or a local news station.  

The affidavit said Smith told an undercover investigator how to make a car bomb last month.  He was arrested Saturday. 

First Infantry Public Affairs Director Lt. Col. Terence Kelley said, "These allegations violate our Army Values so we take them very seriously."

Smith entered the Army from Conway, South Carolina. 

If convicted, Smith could face up to 20 years in federal prison and a fine of up to $250,000
