Korbein Schultz was an army intelligence analyst with the First Battalion of the 506th Infantry Regiment at Fort Campbell, Leventis said. He was arrested earlier Thursday.
"He traded our national defense information for cash," Leventis said. He received $42,000 over 14 payments, he said.
The indictment charges Schultz with six counts, including conspiracy to unlawfully communicate defense information, unlawful export of defense articles to China and bribery of a public official, Leventis said.
