Chinese troops wore QR codes on their body armor in the massive parade
As Chinese troops
were paraded out for their country’s National Day Parade in Beijing on Tuesday, several of them wore a distinct marking on their uniforms.
Affixed on their ballistic vests were what appeared to be a Quick Response (QR) code.
US service members do not use QR codes on their uniforms but have Velcro tabs to affix distinct markings, including rank and service branch, primarily for identification purposes.
