Air Force Security Forces member Zachary Sizemore pleaded guilty Monday to selling military equipment online, according to the Dayton Daily News.

Sizemore pleaded guilty to one count of theft and unlawful sale of government property in the Eastern District of New York. He is scheduled to be sentenced June 29.

The bill of information shows that from July 2013 to November 2016, Sizemore sold Air Force night vision equipment in New York and elsewhere for more than $1,000. He was arrested at his home in Huber Heights, Ohio, according to a federal prosecutor and court documents filed in Dayton's U.S. District Court.

He is alleged to have sold 38 pieces of military equipment on eBay for $50,000. Most recent sales included night vision goggles and thermal monoculars, according to a complaint and affidavit written by an agent with the Defense Department’s Criminal Investigative Service, the Dayton Daily News reports.

Maximum punishment for more than $1,000 worth of government property is 10 years in prison and a $250,000 fine. Sizemore is described as a Security Forces armorer responsible for military equipment and night vision devices.
