The Government Accountability Office issued a report today revealing that undercover government investigators have been able to buy sensitive military goods online, including night-vision goggles, body armor and even plane and helicopter parts.

The report also mentioned another item GAO investigators were able to buy online from sellers on eBay — infrared tabs worn on combat uniforms by U.S. troops.

“Enemies,” the report states, “could use [infrared] tabs to pose as a friendly fighter during night combat, creating confusion on the battlefield and putting troops at risk.”

The GAO’s findings match the surprising results of a recent NBC News investigation. NBC News discovered that combat uniforms and special equipment designed to protect U.S. troops in war zones are widely available for sale, potentially endangering U.S. soldiers’ lives.
