A U.S. Army soldier in Texas with a top security clearance has been charged with handing over sensitive information about the military’s main battle tank in exchange for Russian citizenship.

Taylor Adam Lee, 22, was arrested Wednesday on charges of attempted transmission of national defense information to a foreign adversary and attempted export of controlled technical data without a license.

“This arrest is an alarming reminder of the serious threat facing our U.S. Army,” said Brigadier General Sean F. Stinchon, the commanding general of Army Counterintelligence Command.

Several documents contained technical data that Lee wasn’t authorized to provide, prosecutors said. 

Other documents on the SD card were marked as Controlled Unclassified Information (CUI), and featured banner warnings and dissemination controls. During the meeting, Lee allegedly said that the information on the SD card was sensitive and likely classified.

Lee also discussed obtaining and providing a specific piece of hardware inside the M1A2 Abrams tank to the Russian government, authorities said. On July 31, he delivered what appeared to be the hardware to a storage unit in El Paso.

He then sent a message to the individual he believed to be a representative of the Russian government stating: “Mission accomplished.”

“Today’s arrest is a message to anyone thinking about betraying the U.S. – especially service members who have sworn to protect our homeland,” said Assistant Director Roman Rozhavsky of the FBI’s Counterintelligence Division. “The FBI and our partners will do everything in our power to protect Americans and safeguard classified information.”

Lee’s arrest came on the same day that a soldier shot five other soldiers in Fort Stewart, Georgia. Sgt. Quornelius Radford, 28, shot five soldiers in the 2nd Armored Brigade Combat Team (ABCT) area of the installation, authorities said. 

All the soldiers were treated on-site and then transported to Winn Army Community Hospital, according to Fort Stewart officials. Radford, who has been apprehended, serves as an automated logistics sergeant assigned to the ABCT.
